Microwave dried vegetables
There are many kinds of vegetables in the market, many of which are dried and sterilized. The microwave drying and sterilizing machine of vegetables produced by the Leader Microwave Equipment Company has unique use in drying vegetables. Microwave drying process can not only save energy, but also can effectively improve the quality of products, with energy saving, environmental protection, health and other prominent features, in line with the concept of green, environmental protection, energy saving development.
Advantages of microwave drying equipment for vegetables：
1.Low drying temperature
The production process of microwave drying technology is 30%-50% lower than that of traditional drying technology.
2.The quality is good
The vegetables produced by vegetables microwave drying equipment are of good color and stable quality.
3.Short drying time, strong fragrance
The process of microwave dehydrating and drying vegetables, use microwave vegetables drying machine takes less time than the traditional way, and the vegetables they produce are fragrant strongly.
4.Uniform heating and drying
Because water molecules absorb microwaves best, the part with the highest water content absorbs more microwave power than the part with the lowest water content. This is the characteristic of selective heating, which can be used to achieve uniform heating and uniform drying.
5.Energy conservation and efficient
Microwave is directly on the material, so there is no additional heat loss, the vegetable microwave drying equipment the box of the air and the corresponding containers will not heat. So the thermal efficiency is very high, the production environment is also significantly improved, compared with far infrared heating can save 30% of electricity.
6.Easy to control, advanced technology
Compared with the conventional method, the vegetable microwave drying equipment can use instantly after start machine. No thermal inertia, flexible operation, easy to learn. Microwave power is adjustable. In microwave heating, drying. No waste water, no waste gas, is a safe and harmless high-tech. Improve product quality and bring economic benefits.

Disadvantages of traditional drying equipment：
1.Low output and high energy consumption
Compared with the microwave drying machine for vegetables, the yield of the traditional dryer is not high, and the average drying power consumption is high. The material cannot be dried, the moisture exceeds the control index, and the drying effect of the product is not good.
2.Low production efficiency and short service life
The gas purification system of traditional dryer drying operation is prone to condensation, wet bottom and other phenomena, not only affecting production, but also shortening the service life of the equipment, increasing maintenance costs.
3.Severe air leakage, heat exchange difficult
In the drying process of traditional dryer, the power of flue gas flow is formed by the negative pressure gradient of induced draft fan. Due to the counterflow drying system feed inlet and exhaust air outlet, outlet and hot air inlet are respectively in the same position, causing serious air leakage, the system can not form a stable negative pressure, induced draft fan can not form a stable negative pressure power, this situation makes it difficult for hot air from the heating system to enter the dryer to maximize heat exchange.
Working principle of vegetable microwave drying equipment：
The pure hot air generated by the hot air stove in the vegetable dryer, the temperature of which is 50-160 can be controlled, heating drying and ventilation drying were used simultaneously. Strengthen the reasonable adjustment of hot air ventilation, turn over the multi-layer drying box, dry layer by layer, make full use of hot air, dry and dehydrate quickly and high efficiently operation.

At present, microwave drying equipment has been widely used, the use of vegetable microwave drying equipment, food microwave drying equipment, Chinese medicinal materials microwave drying equipment and other equipment are praised by the majority of users. In the society of continuous progress today, microwave drying equipment will usher in an unprecedented opportunity for development, not only benefits the vast number of consumers, but also has played a great role in promoting the cause of energy conservation and emission reduction, I believe that the microwave industry will be more brilliant in the future!
