Rose tea is a kind of reprocessed tea in China, which is made of tea and rose flowers scenting. The semi-open roses have the best quality. Rose tea sweet aroma, strong aroma, taste sweet.
Rose tea
China’s main production areas are guangdong, fujian, zhejiang, shandong and other provinces, guangdong mainly produces rose black tea, fujian mainly produces rose green tea, zhejiang mainly produces rose jiuqu red plum, shandong mainly produces rose scented tea.
Microwave Blanching of Rose Tea
Microwave blanching equipment for rose can inhibit its fermentation, destroy and passivate oxidase activity in fresh leaves through high temperature or other methods, inhibit tea polyphenols in fresh leaves, prevent discoloration in drying process, and maintain its inherent green color. At the same time, reduce the moisture in the leaves, make the leaves soft, facilitate further processing, and promote the formation of product aroma.
Mr. Sun of pingyin has planted dozens of mu of roses with large quantity. The traditional hot air infrared blanching method is difficult to control the temperature, resulting in low quality and low added value of the dried roses. So Mr. Sun plans to introduce an advanced microwave de-enzyming production line and bring samples to the factory for inspection.
Microwave blanching equipment
Using 18kw tunneled microwave equipment, the 2kg material was tiled 3cm thick in the conveyor belt. The power of the microwave was 65% and 18HZ was transmitted. The material was heated to 80℃ for 7 minutes, weight surplus was 1642g, weight loss was 358g, weight loss rate was 17.9%.
Take the material 2kg, thickness 2cm, microwave high power 100%, transmission 14HZ, 9.5min, infrared temperature rise to 75℃, residual weight 1336g, weight loss 33%;
Electricity can replace the way of burning coal and wood, no noise, no smoke, no dust, and microwave has a strong bactericidal effect, rose safety and sanitation. 4~60kw equipment is provided for customers, and the production per hour is 20~400kg, which is simple to operate and easy to maintain. The de-enzyming yield is 20~400kg per hour. Adopt advanced manufacturing technology and PLC control, make it become intelligent high-tech equipment. General electricians can master the daily maintenance and repair of equipment after short training.
Microwave de-enzyming equipment adopts the special technology of microwave, using the thermal effect and biological effect of microwave at low temperature (60-80 degrees Celsius), to rapidly passivate the oxidase activity, so that the material components are not destroyed by high temperature, fast and efficient. Due to its fast de-enzyming speed, high efficiency, good effect, while de-enzyming, also can remove about 10% of the water, and the de-enzyming effect is much better than the traditional de-enzyming effect.
