Introduction to leech：

  Leeches grow and reproduce in inland freshwater waters, and dried leeches can be used as medicine after infusion. In recent years, it has been newly discovered that leech preparations have special effects in anti-cancer. Due to the abuse of pesticides and fertilizers in recent years, and the environmental pollution caused by the "three wastes" of industry and agriculture, wild natural resources have declined sharply. With the in-depth development of the medicinal value of leeches, its market demand potential is huge.

Leech processing steps:

  Pick up the leeches, the leeches are a good product, and then put the cleaned leeches in a container, and pour high-level liquor to submerge the leeches. Seal the leeches for about half an hour. At this time, the leeches are already drunk. Take them out and wash them with water and place them on a gauze net. Leave them in the air in a ventilated place for about 45 hours to dry. Note: Drying and draining should be evenly spread and should not be stacked together. The second step is to evenly put the drained leeches on the material pan screen, load them into the material cart, and prepare for drying.

Leech drying process：

  Set the parameters required for drying leeches on the operation panel of the air energy dryer. The specific parameters are set as follows: the temperature is set to 45°C, the relative humidity of the drying is set to 10%, the drying time is 6 hours, and the drying + dehumidification mode. The temperature is set at 50°C, the drying relative humidity is set at 10%, the drying time is 4 hours, and the drying + dehumidification mode. The temperature is set at 60°C, the drying relative humidity is set at 10%, the drying time is 4 hours, and the drying + dehumidification mode. The temperature is set at 65°C, the drying relative humidity is set at 10%, the drying time is 3 hours, and the drying + dehumidification mode. The temperature is set at 60°C, the drying relative humidity is set at 10%, the drying time is 1 hour, and the drying + dehumidification mode. The drying of leeches generally takes 17-18 hours. After drying, the quality of the finished product is inspected.

Precautions:
The processed leeches should be naturally flat, slightly raised on the back, flat abdomen, brittle and easy to break, and the cross-section is glued and shiny.

Recommendation of leech dryer/drying machine

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation

  Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.

  Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
