A kind of drying equipment for Chinese herbal medicine
Technical field
The utility model relates to a kind of drying equipment for Chinese herbal medicine, belongs to the medicinal herbs processing machine technical field.
Background technology
The Chinese medicine that monkshood etc. are adopted rear difficult preservation generally adopts coal heating, drying or electrical heating oven dry.There is following problem in the Chinese medicine oven dry techniques such as present monkshood: (1) high temperature causes active ingredient loss in the medicinal material; (2) the high temperature drying process such as coal heating cause medicinal material contaminated or produce, the accumulation harmful substance; (3) consume of the high temperature drying energy is large, and the techniques such as coal heating are more serious to ambient influnence.This technique is dried than energy-conservation more than 50% with electric energy; Changing the unfriendly type production technology of present environment is process for cleanly preparing, for production safety medicine, raising enterprise profit, development low-carbon economy are made contributions.
There are some hidden danger in these techniques: (1) high temperature causes active ingredient loss in the medicinal material; (2) the high temperature drying process such as coal heating cause medicinal material contaminated or produce, the accumulation harmful substance; (3) consume of the high temperature drying energy is large, and the techniques such as coal heating are more serious to ambient influnence.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of drying equipment for Chinese herbal medicine for the deficiencies in the prior art.
A kind of drying equipment for Chinese herbal medicine comprises predryer, hothouse, hot air chamber, Yu Wen recycling chamber, solar thermal collector, heat pump, and wherein predryer is connected with hothouse, between predryer and the hothouse blower fan is set; Sun wall heat collector will be sent into hothouse by hot air chamber through the air of preheating, add thermal material after, air is sent into predryer through blower fan, finally by Yu Wen recycling chamber by heat pump with heat recovery.
Described drying equipment for Chinese herbal medicine, the indoor heat pump condenser (14) that arranges of described remaining temperature recycling, heat pump condenser (14) is transported to heat pump condenser (8) by pipeline (13) with the indoor heat recovery of remaining temperature recycling, and heat pump condenser (8) is arranged in the hot air chamber.
This drying equipment for Chinese herbal medicine adopts heat pump and heliotechnics, and to be lower than 75 ℃ Chinese medicines such as temperature oven dry monkshood, (1) can guarantee that the quality of medicinal material is not subjected to temperatures involved; (2) compare with electric energy heating, energy-conservationly surpass 50%, reduce production costs; (3) process for cleanly preparing is preserved the ecological environment.
Description of drawings
Fig. 1 is the structural representation of the utility model drying equipment for Chinese herbal medicine.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
With reference to figure 1, drying equipment for Chinese herbal medicine comprises predryer 1, hothouse 3, hot air chamber 6, Yu Wen recycling chamber 15, solar thermal collector (being connected with hot blast import 10 among Fig. 1), heat pump (being connected with pipeline among Fig. 1 7), wherein predryer 1 is connected with hothouse 2, between predryer 1 and the hothouse 2 blower fan 2 is set; Sun wall heat collector will be sent into hothouse by hot air chamber 6 through the air of preheating, add thermal material after, air is sent into predryer 1 through blower fan 2, finally by Yu Wen recycling chamber 15 preheating is recycled.To be lower than 75 ℃ Chinese medicines such as temperature oven dry monkshood, can guarantee that the quality of medicinal material is not subjected to temperatures involved; Compare with electric energy heating, energy-conservationly surpass 50%, reduce production costs; Process for cleanly preparing is preserved the ecological environment.
Air is connected with hot air chamber 6 by a Fans 9 behind the sun wall heat collector heat temperature raising when fine, by hot air chamber 6 hot blast is introduced hothouse 3, and the material bed thermal material that adds that hot blast passes on the storage car 4 makes water evaporates; Damp-heat air is introduced predryers 1 by another centrifugal blower 2, pass from bottom to top in the predryer 1 behind the dry bed of material, tail gas is sent into the heating of sun wall heat collector by blower fan again by return air circulation pipe 11, consists of the closed cycle of heat collector and dry kiln; Along with the hothouse temperature raises, the reflux airflow water capacity increases (hot air chamber 6 interior temperature, the humidity sensors 5 of arranging, air themperature and humidity that monitoring enters hothouse 3), at this moment open the heat collector air inlet and introduce fresh air, after heating, send into hothouse 3, hothouse 3 interior humid air discharged to outdoor, are done the open circuit circulation through dehumidification tube 12.When needing auxiliary thermal source work at cloudy day or night, only need close sun wall heat collector air-supply passage, and unlatching heat pump air delivery duct gets final product.The inlet and outlet mouth of system all is equipped with choke valve, can suitably regulate aperture, the control ventilation.
The Yu Wen recycling chamber 15 interior heat pump condensers 14 that arrange, heat pump condenser 14 is transported to heat pump condenser 8 by pipeline 13 with the heat recovery in the remaining temperature recycling chamber 15, and heat pump condenser 8 is arranged in the hot air chamber 6, takes full advantage of heat energy.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
