Chinese medicine Pieces drying method

Chinese medicine Pieces in the production generally need to be dried and then stored, otherwise the quality. The dry way is mainly natural and mechanical two types.
One, naturally dry
Natural dry is to cut the good drink set in the sun drying or cool and ventilated place dry. Drying method and dry method do not need special equipment, such as cement floor, plaque, mat, bamboo pad, etc. can be applied. With the advantages of economic convenience, low cost. But this law covers a large area, susceptible to climate, Pieces are not too health.
Second, mechanical drying
Mechanical drying is the use of drying equipment, the slices for drying. Its advantages are not affected by the climate, than the natural dry health, and can shorten the drying time.
1. Flap dryer
How it works: The cut pieces are fed into the drying room via the feeding conveyor. Indoor for a number of flaps or mesh belt conveyor belt. Up and down the multi-storey, by the sprocket drive, drug flat on the flap, from the front end to the end, and then into the lower, was several reciprocating drive. Unloading along the outlet.

2. Hot air circulation dryer
Working principle: the Pieces into the network disk, layered placed in the drying rack, by the track into the box. After the air is heated, the fan acts in the box to complete the heat exchange, so as to achieve the drying effect. After the pieces were dried, the drying rack was pulled out and the dried pieces were collected. This way simple structure, flexible operation, suitable for multi-species production.

3. Far infrared radiation drying technology: energy conversion to far infrared radiation energy, the molecules of the dry body absorbs after the resonance, causing the molecules, atoms of vibration and rotation, resulting in the body heat, so that the water into the gas diffusion to achieve drying effect. It is characterized by fast drying speed, with a high bactericidal, insecticidal and ovulation ability.

4. Solar and heaters drying technology Solar energy is a huge clean low-density energy, suitable for low temperature drying. Its characteristics are: saving energy, reduce environmental pollution, drying quality, to avoid the dust and insects and natural pollution of the drug after the dry variegated and black hair phenomenon, improve the appearance of quality.
