 What are the advantages of microwave vacuum drying equipment compared with conventional vacuum drying?

Conventional vacuum drying is to transfer heat from the outside to the material heat according to the principle of heat conduction. Heat is always transferred from the outside to the inside to heat the material. The transfer speed is slow and the heating time is long.And there is inevitably a temperature gradient in the material, so the heating material is not uniform, resulting in local overheating of the material.

Different from traditional heating methods, microwave heating is a kind of heating method that relies on the absorption of microwave energy by an object to convert it into heat energy, so as to raise the temperature of the whole body at the same time.It has a strong penetrating ability. Through the high-frequency reciprocating motion of dipole molecules inside the heated body, internal friction heat is generated to increase the temperature of the heated material. Without any heat conduction process, the material can be heated internally and externally at the same time.The heating speed is fast and uniform, only a fraction or a few tenths of the energy consumption of traditional heating method can achieve the heating purpose.Its heating efficiency is 2〜10 times higher than conventional vacuum drying equipment.

Chinese medicinal materials sterilization why use Microwave Equipment?

Traditional Chinese medicinal materials refer to the famous and excellent genuine medicinal materials with Chinese characteristics that are traditionally recognized by people and come from specific production areas.In recent years, Chinese herbal medicine is also an important export commodity to earn foreign exchange.

Chinese medicinal materials sterilization why use Microwave Equipment?

The quality of Chinese medicinal materials depends on the drying and sterilization, so drying and sterilization is an important factor affecting the quality of Chinese medicinal materials.

The Chinese herbs microwave decocting machine is more natural drying, but for its own, natural drying cannot be sterilized, secondly killing the bacteria of Chinese medicinal materials is very important, so in the selection of Chinese medicinal materials drying and sterilizing equipment, most of the Chinese medicinal materials businesses will choose to use microwave Chinese medicinal materials insecticidal equipment for drying and sterilizing.

At present, the common drying methods of Chinese medicinal materials are as follows:

1.Drying method

One of the most common drying methods for most medicinal materials is drying.Choosing sunny, windy weather air to bask in, thin spread medicinal materials on the ground, use daylight illumination.

At the same time, attention should be paid to the timely turnover, ensure the uniform exposure of sunlight.Night air humidity is large, the need to put away the medicinal materials well to prevent the return of moisture.

2.Air-dried method

This method is often used in rainy weather, or for medicinal materials containing volatile oil and easy to run oil, discoloration of medicinal materials, such as jujube seed, cypress seed, anemone, bitter almond, codonopsis pilosula, asparagus officinalis, and so on.These medicinal materials should not be exposed to the sun, but in the sun is not too strong place or ventilated shade stand drying.

3.Oven drying

Drying room is not restricted by the weather, can achieve the effect of insect repellent.However, it needs to be operated by professionals who are familiar with the drying technology. Attention should be paid to building the drying room according to the technical requirements and standards of the specification.It needs to control the drying temperature and time according to different properties of medicinal materials.

4.Far infrared heating and drying method

Its drying principle is to transform electrical energy into far-infrared radiation, which is absorbed by the molecules of the medicine, producing resonance, causing the vibration and rotation of molecules and atoms, and causing the object to become hot. Through thermal diffusion, evaporation and chemical changes, the purpose of drying is finally achieved.

5.Microwave drying equipment

This is a new technology rapidly developed in the 1960s. Microwave insecticidal equipment for Chinese medicinal materials uses induction heating and medium heating to make water and fat in Chinese medicinal materials absorb microwave energy in different degrees and convert it into heat so as to achieve the purpose of drying.

Microwave drying insecticidal machine can kill microorganisms and mold, and has disinfection effect, so that the medicinal materials reach the hygienic standard, in line with GMP certification, and can prevent the medicinal materials in the storage process of mildew and insects.

Microwave drying and sterilization equipment for Chinese medicinal materials has two major functions:

Flashdrying:The first is to use the basic principle of microwave. Polar water molecules and fats in Chinese medicinal materials and processed products can absorb microwave energy at different levels.In the alternating current electric field, the change of electric field time makes polar molecules produce rotational vibration, which causes the mutual friction between molecules and generates heat, thus achieving the purpose of drying and sterilization.

Because microwaves can penetrate deep into the raw material, the drying time is usually between 1/10 and 1/100 of that of hot air.Therefore, the loss of volatile substances and aromatic components in traditional Chinese medicine is less.It is characterized by fast speed, short time, symmetrical heating, good product quality and high thermal efficiency.

Sterilizing effect:Microwave sterilization is not affected by the environmental pollution of fuel waste gas emissions, can eliminate microbial strains and molds, with disinfection and sterilization function, but also can prevent mold and insects.

It’s a physical method of sterilizing that eliminates bacteria, molds and insect eggs, as well as bacteria that harm the body, such as viral infections, without adding chemical preservatives.In the process of eliminating harmful microorganisms, it will not be toxic to the residual materials or radioactive substances pollution, health and safety non-toxic.It will not change the color, taste and nutritional value of the material.

Characteristics of microwave insecticidal equipment for Chinese medicinal materials:

1.High degree of drying, short time, fast speed.

2.Good drying quality, low temperature sterilization, maintain the internal quality and color of medicinal materials.

3.The drying effect is uniform and thorough.

4.The structure of drying equipment should be simple, parts simple standardization, easy to operate, easy to use control system, easy to maintain.

5.Energy efficient.Microwaves act directly on the material, so there is no additional heat loss.

Through the above comparison, we can see why Chinese medicinal materials need microwave equipment for sterilization.Microwave insecticidal machine for Chinese medicinal materials uses microwave low-temperature insecticidal and bactericidal technology, which can kill larvae, adult worm and bacteria at a lower temperature.

Microwave deworming process does not harm the effective ingredients of Chinese medicinal materials, and can achieve the required sterilization and deworming effect at low temperature and in a short time with conventional thermal and chemical deworming.

Increasing the storage period of Chinese medicinal materials has obvious effect on improving product quality.Microwave drying has become one of the most important drying methods for Chinese medicinal materials due to its advantages of fast drying speed, symmetrical drying, good product quality, selective heating and drying, high thermal efficiency and sensitive reaction.

The advantage and principle of chain plate Microwave Wood Drying Equipment

Since the reform and opening up,China’s wood drying industry has been rapid development, has become a perfect industrial system.Especially in recent years, with the gradual increase of China’s wood consumption, the wood drying market is more prosperous, which brings a good opportunity for the rapid development of China’s wood drying industry.

The advantage and principle of chain plate Microwave Wood Drying Equipment

The Microwave hot air dehydrating drying machine LD1504 has the following advantages:

1.Chain plate microwave wood drying equipment has fast drying speed.

When Chain plate microwave wood dryer drying wood,because heat is not coming from the outside of wood,friction between water molecules and wood directly generate heat inside the wood, it also known as volume heating.

This volumetric heating causes the heat transfer of the dried wood to occur almost simultaneously along the entire thickness, and the time required for heat transfer is independent of the thickness of the wood.

The moisture inside the wood quickly vaporizes, creating outward diffusion pressure, and at the same time, there is heat loss and water evaporation on the wood surface.In fact, the internal temperature of wood is higher than the surface temperature, so the microwave drying temperature gradient and moisture content gradient direction is the same, greatly accelerating the movement of water speed.

2.Chain plate microwave wood drying machine has good drying quality.

Due to increased permeability during wood drying in the chain plate microwave wood drying production line,During the drying process, the heating is uniform, and the water in the wood is discharged from the inside out at the same time, so that the expansion and contraction coefficient of the wood are basically the same.The defect such as deform, craze that can avoid lumber to appear in drying process to the largest extent so, and dry even.

3.Microwave wood drying equipment can maintain the original color of wood.

The higher the temperature, the longer the action time, the higher the moisture content, the faster the wood discoloration.Compared with conventional drying, the microwave drying cycle of wood should be shortened by tens to hundreds of times.In addition, each heating process from low temperature to high temperature,the duration of stay at high temperature is shorter.So the chain plate microwave wood drying equipment almost does not change the original color of wood.

4.Chain plate microwave wood drying equipment can directly dry wood semi-finished products.

The biggest characteristic of wood microwave drying equipment is that it can dry semi-finished products of wood products.Microwave drying molding wood directly, no deformation, no cracking, no damage to the wood, and occupies a small area of the site, with a certain degree of insecticidal function.

Main methods of modern drying technology:

1.Air pre-drying technology utilizing natural energy, solar drying technology, and drying technology combining solar energy and other drying technologies;

2.Surplus hot water drying technology of power plant and boiler exhaust drying technology using waste energy;

3.Waste combustion drying technology;

4.Intelligent drying technology, that is to use the intelligent control technology of wood drying to achieve intelligent and efficient drying of different wood;

5.Efficient combination of different drying methods;

6.Wood pretreatment and drying technology enhances wood moisture conductivity through modern biological technology, mechanical technology and chemical treatment technology.Finally it can improve wood drying performance.

Principles of chain plate microwave wood drying equipment produced by Leader Microwave Equipment Company:

The principle of chain plate microwave wood drying equipment for wood drying using wet wood as the dielectric, water molecule polarization in wood is caused by the action of microwave electromagnetic field.Meanwhile, due to the frequent alternations of electromagnetic fields, water molecules frequently swing at high speed and generate heat by friction, thus heating the dry wood.

As a kind of special heat conduction way,microwave technology converts electromagnetic energy into heat energy.It not only has a wide range of uses in food heating, insecticidal sterilization, dry preservation and other aspects,but also develops to the application of catalytic chemical reaction and microwave treatment of new materials.A variety of microwave agricultural and sideline products, leisure food sterilization equipment also mushroomed.

With the continuous in-depth development and improvement of microwave drying technology in wood processing,it will make the wood processing more safe, energy-saving, efficient and environmental protection, so as to drive the economic growth of China’s wood industry and promote the rapid development of environment-friendly society.

Why use Microwave Resin Drying Equipment drying resin powder?

Drying technology has been widely used in food, biology, metallurgy, chemical industry and other aspects, involving all aspects of national economy, affecting all aspects of national life.Therefore, the development of better drying technology is the key to break through the shortage of existing drying technology.Microwave resin dryer has many unique advantages.

Why use Microwave Resin Drying Equipment drying resin powder?

Drying principles of microwave resin drying equipment:

The microwave drying technology of microwave resin powder drying equipment has a unique heating mechanism which is different from conventional drying.It is mainly manifested in the difference of migration potential and its gradient direction.

In traditional heat drying,a heat source transfers heat from the outside to the inside of the resin,evaporating the water.The initial impetus for energy transfer is the temperature gradient. Water is transferred from the inner layer of the resin to the surface layer to the hot wind in the form of steam,which needs to overcome the resistance of the air film.In the conventional drying process, the diffusion direction of steam is opposite to the temperature gradient, which  blocked diffusion and reduced heat transfer efficiency.

In the heating process of the Microwave resin drying machine produced by  Leader Microwave Equipment Company,the absorption of heat energy and dehydration process of dried resin powder are not completely determined by the thermal conductivity properties of the drying medium and itself.So the thermal resistance is negligible.

The dielectric loss factor of a substance is proportional to its absorbing property, that is to say, a substance with a large loss factor can better absorb microwave energy in the microwave field.From the macro point of view, microwave is preferred to heat the material with large dielectric loss factor, while the material with small dielectric loss factor is slow to be heated, that is to say, microwave has the characteristic of selective heating.

Since the dielectric loss factor of water is much higher than that of common minerals or materials, microwave can selectively heat water, rather than the whole resin powder, so the microwave radiation has unique advantages in water removal during the drying process.

As a new drying method, microwave heating has the characteristics of selective dielectric heating, high dehydration efficiency and energy saving:

1.Compared with conventional drying method, microwave drying equipment can dry resin powder quickly and efficiently.

In the drying process of resin powder microwave drying equipment,all the water in the powder, namely the inner layer and the surface layer, is selectively heated by microwave at the same time. When the water is heated, it will instantly vaporize, while the inner layer and the surface layer of the gas film and air of the powder will produce a huge pressure difference, forming a huge driving force, so that the water will quickly transfer from the powder to the air.

Microwave drying resin powder equipment heating does not need any heat conduction process, directly through the microwave in the resin powder dielectric loss to transfer energy to molecules or atoms, this unique in situ energy transfer mode is different from the traditional heat transfer mode, is conducive to improve the chemical diffusion process and chemical reaction rate.

2.Microwave tunnel type Tenebrio molitor drying and puffing equipment has uniform drying temperature,consistent with the inside and outside.In the drying process of microwave drying equipment, the temperature gradient and heat transfer direction inside the resin powder are the same as that in the water vapor transfer direction, so it is characterized by internal and surface heating, high thermal energy utilization and energy saving.

3.The adhesion, hardness, impact resistance and flexibility of the resin products treated by microwave resin drying equipment have been improved significantly.

4.Microwave resin drying equipment has no pollution in the production process and protects the environment.

Microwave heating and drying process without waste water, waste gas, etc.It is a great improvement to the traditional drying process, further popularization of microwave resin drying equipment, kraft paper bag microwave drying equipment and other microwave equipment can improve environmental damage, which has good social benefits.

Microwave drying technology has unique heating and heat transfer mechanism, and has obvious advantages compared with conventional drying technology: selective heating, high dehydration efficiency, low energy consumption and improving the performance of resin powder.

Microwave drying technology shows many advantages, making it become a highly efficient, energy-saving, economic new technology in the field of drying, which is bound to play an increasingly important role in the material, metallurgy, chemical, food and other industrial production.

Present situation and prospect of Microwave Dryer

Dried fruits, dehydrated vegetables, dried fruits, etc. that we often eat in our daily life are all dehydrated through drying.Microwave drying machines can remove moisture, so that bacteria, yeast and mold can not grow, ultimately conducive to food preservation.The fruit is then dried or dehydrated to make it lighter and smaller.

Present situation and prospect of Microwave Dryer

There are many ways to dry food. The traditional way is to dry it in the sun.But this way of drying, depending on the weather.Drying time is too long, later preservation is also easy to live insects, can not guarantee the color and nutrition of food.Food integrity may also be damaged during transportation.

Microwave drying is a new drying method.During drying, microwaves can be converted into heat energy by acting directly on dielectric molecules.Due to its penetrating properties, microwave can heat the medium inside and outside at the same time without heat conduction, so the heating speed is very fast, and the drying speed can be shortened hundreds of times for the food with water content of less than 30%.

Advantages of microwave drying equipment:

1.Drying quickly

Hot air circulation oven is completely different from traditional drying method.It is the process by which the dried material itself becomes a heating element without heat conduction.Therefore, even the materials with poor thermal conductivity can reach the drying temperature in a very short time.

2.Uniform drying

No matter how the shape of each part of the object, microwave drying can make the object at the same time uniform penetration of electromagnetic waves and generate heat energy.So the drying uniformity is good, will not appear outside the coke endogenous phenomenon.

3.Energy conservation and efficient

Since substances containing water tend to heat up by absorbing microwaves, there is little loss except for transmission.Therefore, high thermal efficiency and energy saving.It can save more than 1/3 energy than infrared drying.

4.Anti-mildew, sterilization,keep fresh

Microwave drying has thermal and biological effects, and can sterilize and prevent mildew at lower temperature.As the drying speed is fast and the time is short, it can maintain the activity of the material to the maximum extent and preserve the vitamin, original color and nutrition in the food.

5.Advancedtechnology

Immediate drying and termination can be achieved by controlling microwave power.The programmable automatic control of drying process and drying process specification can be carried out by using man-machine interface and PLC.

6.Safe and innocuous

Because microwave energy is controlled in the drying room made of metal and waveguide tube, so microwave leakage is very rare, no radiation hazards and harmful gas emissions, no waste heat and dust pollution, neither food pollution, nor pollution of the environment.

The drying process involves almost all sectors of the national economy and is widely used in production and life.The purpose of drying is to remove water or solvents from certain raw materials, intermediate and finished products for processing, use, transportation and storage.

With the development of science and technology, such as biological products, new materials (multiphase composite materials, nanomaterials, intelligent materials and biomedical materials, etc.), advanced ceramics, new advanced food and new pharmaceutical products, the traditional drying technology and dryer are not always adapted to the actual production needs.

Microwave drying technology and microwave dryer have been widely used in light industry, chemical material industry, food and agricultural products processing industry and other industries and showed significant advantages.Microwave drying is undoubtedly a new technology to meet the requirements of new products.

Dehydration principle of LD1503 fruit and vegetable continuous vacuum microwave dehydrator:

In the vacuum environment, the boiling point of water in the raw material of fruits and vegetables decreases with the increase of the vacuum degree, The water molecules are converted from liquid boiling into water vapor and actively overflow from the raw materials of fruits and vegetables, and are extracted from the outside by the vacuum pump to achieve the purpose of drying.

Microwave heating is an extremely high-frequency electromagnetic oscillation that acts on the material molecules with electrodes, causing the molecular arrangement to change dramatically, resulting in a fierce “friction”-like effect. Make the object hot. This process converts the electromagnetic field energy of the microwave into thermal energy. Water molecules are polar molecules that strongly absorb microwaves. When the fruit and vegetable materials containing moisture are subjected to microwave radiation of sufficient field strength, the water molecules absorb the microwaves and quickly evaporate, the fruits and vegetables are quickly dried.
