Tea microwave dryer can kill, dry and sterilize all kinds of tea, and can be dried at low temperature.
Destroy the nutrients in tea. The advantages of microwave tea green-killing drying equipment are as follows:
1. Tea leaf microwave drying machine heates rapidly and evenly.
Microwave heating is different from traditional heating method. It does not need heat conduction process. It makes the heated material itself become a heater. Therefore, even the material with poor heat conductivity can reach the heating temperature in a very short time. Regardless of the shape of each part of the object, it makes the surface of the material infiltrate the electromagnetic wave at the same time to generate heat energy, which is not limited by the shape of the object, so the heating is more uniform and the phenomenon of endogenous external focus does not occur.
2. Energy saving and high efficiency of tea microwave dryer.
Because the substance containing water is very easy to absorb microwave and heat, there is almost no other loss except a small amount of transmission loss.Compared with far infrared heating, microwave heating can save more than one third of energy.
3.A kind of tea microwave dryer has anti-mildew and sterilization, and does not destroy the nutrient components of materials.Microwave heating has thermodynamic and biological effects, so it can kill molds and bacteria at lower temperature. Traditional heating method has a long heating time, resulting in a greater loss of nutrients, while microwave heating is rapid, which can maximize the preservation of the activity of materials and nutrients in food.
4. Tea leaf microwave drying machine has advanced technology and can be continuously produced.
Heating or termination can be achieved by controlling microwave power. PLC man-machine interface can be used for programmable automation control of heating process specification. It has perfect transmission system, which can ensure continuous production and save labor.
5. Tea dried by microwave dryer is safe and harmless.
Microwave is controlled to work in the heating room made of metal. Microwave leakage is effectively suppressed. There are no radiation hazards and harmful gas emissions, no waste heat and dust pollution, no physical pollution and no environmental pollution.
