Material to be dried→Special lower hopper→Conveyor belt→Microwave suppressor→Microwave heating drying oven→Dehumidification system→Temperature control system→Microwave suppressor→Outlet hopper finished product Why use Chinese medicine dry machine? Microwave drying equipment Features:
1. Selective heating. Since the water molecules absorb the microwave well, the portion with a high water content absorbs more microwave power than the portion with a lower water content. This is the characteristic of selective heating, which can achieve the purpose of uniform heating and uniform sterilization.
2, energy efficient. The microwave directly acts on the material, so there is no additional heat loss, the air in the furnace and the corresponding container will not heat, so the thermal efficiency is extremely high, the production environment is also obviously improved, and the electricity can be saved by 30% compared with the far infrared heating. .
3. Short time and high efficiency. Microwave heating sterilization is a process in which the object to be heated itself becomes a heating element and does not require heat conduction. The microwave penetrates the inside and outside of the object from all sides and at the same time enables the object to be uniformly heated and sterilized in a short time, which greatly shortens the drying sterilization time and thus improves the yield.
4, easy to control, advanced technology. Compared with the conventional method, the device is ready to use; without thermal inertia, the operation is flexible and convenient; the microwave power is adjustable, and the transmission speed is adjustable. In microwave heating and drying sterilization, there is no waste water, waste gas and waste residue, which is a safe and harmless high-tech.
5, the sterilization effect is good. Practice has proved that the use of microwave sterilization generally kills E. coli at 70 ° C, the total number of bacteria is greatly reduced at 80 ~ 90 ° C, the time is only 2 to 8 minutes. Fast, short time, so retain the nutrients and traditional flavor of the food.
6. Extend the shelf life. Microwave sterilized materials can extend the shelf life of half a year, which has a significant effect on improving product quality and extending storage cycle.
