Selection of equipment commonly used in drying Chinese medicinal materials at present

Artificial drying mainly refers to the drying of harvested Chinese medicinal materials by machine cleaning, slicing, and putting them into drying equipment. Artificial drying generally takes place in relatively closed environment, with less pollution and controllable drying quality. The commonly used drying equipment for Chinese medicinal materials includes microwave oven, heat pump drying equipment, continuous mesh belt drying equipment, microwave drying equipment, etc. The heat pump drying equipment is mainly composed of heat source system and drying room. Heat pump mainly works by compressor, which converts normal temperature and pressure air into high temperature gas, which is conveyed by fan to drying room to heat material. Heat pump drying room is usually equipped with temperature display system, which can accurately control the temperature, moisture removal intensity, heating time and so on in the drying room. As long as you master the drying process skillfully, you can achieve one person and multi-machine operation. The output of heat pump drying equipment varies from 20 kg to 1000 kg, depending on the type and size of drying materials. Heat pump drying equipment is suitable for drying all materials below 75 C, especially for small batches of medicinal materials and insect materials.

Continuous mesh belt drying equipment has the advantages of small floor area, large output, low drying cost and labor saving. Continuous mesh belt dryer can use coal-fired furnace, natural gas furnace, oil-fired furnace, steam furnace, heat pump and other heat sources. The multi-layer structure is adopted in the continuous mesh belt drying equipment box. The transmission shaft drives the mesh belt and the material layer on it to complete the material feeding, transporting, turning and discharging. The mesh belt drying equipment can realize mass drying of various kinds of mosaic, whole herb, rhizome and seed Chinese medicinal materials, with high efficiency, short drying cycle and intact nutrient retention. Microwave drying equipment is mainly used for killing mosaic herbs and drying, sterilization and insecticide of various Chinese herbal pieces. The water content of Chinese Herbal Pieces processed by microwave drying equipment can be reduced to 3% or even lower, and the fragrance is stronger than that of ordinary dried products. It can be directly drinkable and has a good taste. Microwave equipment can also be used for drying and sterilizing bottled medicinal liquids such as pharmaceutical raw liquids, Chinese and Western medicines, nutritional oral liquid, etc.

At present Chinese medicinal materials drying commonly used equipment selection scheme, provide a variety of forms of drying equipment selection scheme and quotation. This article is from the microwave dryer () network.
