1. Fast heating speed: microwave directly heats the inside and outside of tea and flowers at the same time, without preheating, and can be processed after starting up. In traditional production, there is a preheating process that affects the heating speed.
2. Uniform heating: microwave cleaning and drying is to evenly irradiate the electromagnetic wave generated by the magnetron on the tea and flowers, heating inside and outside at the same time, without coke leaf, coke edge, slag, etc., and the product quality is good; Because the surface temperature of tea is not too high, the chlorophyll changes less, the color is green and resistant to storage, the flavor loss is less, and the drying is even.
3. Great sterilization and mellowing effect: microwave treatment can obtain excellent insecticidal effect. When the water content in tea and flowers is less than 12%, it is conducive to enhancing the insecticidal effect, so that the mold in them is no longer alive, thus playing the role of mold prevention.
4. Cell wall breaking effect: Microwave drying and green removing treatment of tea has cell wall breaking effect, improving the yield of effective analysis.
5. Improve working efficiency: The microwave tea drying and bleaching machine adopts automatic feeding and unloading. The operator only needs to press the button to monitor the equipment operation and check the degree of green removal of flowers. It only takes 1-2 people to complete the green removal and drying.
6. Environmentally friendly and pollution-free equipment: microwave disinfection and drying, sterilization and aging, and this machine does not cause environmental high temperature, smoke and noise. It is an ideal pollution-free, "energy conservation and emission reduction" environmental protection equipment in the tea industry at this stage.
The microwave drying and deashing machine for tea thoroughly kills insects and germs through microwave deashing and drying. The product is bright in color, and its chlorogenic acid content is 25% higher than that of ordinary drying. It can be used for drying and extracting oil from roses, fixing and drying honeysuckle, and making all kinds of tea, roses, dandelion, honeysuckle, mint, etc.

The drying temperature of tea is generally controlled at 80 °~130 °. The articles in the vertical multi-layer drying box are dried by layer by layer circulation dehydration, and the wet air is discharged directly from the top layer. The contact time between the wet air and the articles is very short (5 seconds~12 seconds). At the same time, open the observation hole of each layer to discharge moisture layer by layer at any time, so as to completely avoid the "retting" caused by the long contact time between the wet air and the articles.
The drying oven is less of a four layer structure, which is rotated and dried layer by layer.
The traditional hot air dryer is more effective than the microwave tea drying sterilization machine: the heating process of the general hot air dryer is external heating, external drying, and internal heat transfer. The direction of water diffusion and transfer is opposite to its direction, affecting water evaporation. However, microwave heating is internal heating, and the heating speed is fast. Therefore, during the drying process of microwave tea drying and sterilization equipment, the moisture transfer speed of the inner layer is fast, and the drying speed is faster than that of hot air drying. It has the advantages of large drying rate, energy conservation and environmental protection, high production efficiency, dry symmetry, clean production, easy to realize automatic control and improve product quality. Therefore, more and more attention has been paid in various fields of drying.
