A kind of drying equipment of eat/medicinal/feed insect
Technical field:
The invention belongs to the dry field of insect, be specifically related to a kind of drying equipment of eat/medicinal/feed insect.
Background technology:
Insect accounts for 60% of the whole animal kingdom, is a huge resources bank.Insect has broad application prospects in the new industry in the fields such as agricultural, biological medicine, food and health products, feed industry and fine chemistry industry.Insect is rich in protein and various active material, has abundant nutrition.But the water content of living insects is very high, generally exceed more than 70%.One of important process operation that so insect dry is insect to be utilized.Too high bake out temperature can cause the sex change of insect protein and active material, is unfavorable for later use.But at present vacuum freeze drying is conducive to keep the activity of insect protein and active material, but its exist equipment investment cost and subsequent treatment cost high, and the shortcoming such as length consuming time, is unfavorable for commercial applications.
Summary of the invention:
The object of the invention is to research and develop one can carry out rapid draing to insect, and prevents the drying equipment of the eat/medicinal/feed insect of the oxidized sex change of active material of insect, and its simple structure, easily manufactures, and is convenient to industrial applications.
The drying equipment of eat/medicinal/feed insect of the present invention, it is characterized in that, comprise heat preservation and dryness casing, silica gel drier, filter and air heater, on the sidewall of described heat preservation and dryness casing, be provided with carbon dioxide pipe, heat preservation and dryness bottom half is stretched in its one end, one end is stretched out outside casing and is connected with carbon dioxide valve in addition, the top of heat preservation and dryness casing has exhaust outlet, bottom has air inlet, exhaust outlet is connected with hot blast escape pipe, on hot blast escape pipe, be equipped with one-way air pressurizing valve, on the hot blast escape pipe between one-way air pressurizing valve and exhaust outlet, be also equipped with carbon dioxide air outlet valve, other one end and the silica gel drier of hot blast escape pipe, filter, air heater and hot blast air inlet pipe are and are linked in sequence, hot blast air inlet pipe is connected with air inlet again, in hot blast air inlet pipe, be equipped with one-way air pressurizing valve, in heat preservation and dryness casing, be also provided with some layers of pallet, the bottom of pallet is mesh-like, on heat preservation and dryness casing, be also provided with dodge gate, in heat preservation and dryness casing, be also provided with the thermostat of measuring and regulating heat preservation and dryness box house temperature, this thermostat is also connected with air heater electricity, to control air heater opening and closing.
Preferably, above every layer of pallet, be also provided with uviol lamp, for the article in pallet are carried out disinfection.
Preferably, be also provided with mass air flow sensor in the exhaust ports of heat preservation and dryness casing, for measuring the carbon dioxide flow of heat preservation and dryness box house.
Preferably, be also provided with hot blast air dispersing hood at the air inlet place of heat preservation and dryness casing, force hot blast to disperse to enter drying box.
Of the present invention edible/drying equipment of medicinal/feed insect, using the carbon dioxide of lower temperature (40-60 degree Celsius) as mobile drying medium, the insect in drying equipment is carried out to rapid draing, and prevents the oxidized sex change of active material of insect.This simple in equipment, easily manufactures, and is convenient to industrial applications.

Embodiment 1:
As depicted in figs. 1 and 2, the drying equipment of the eat/medicinal/feed insect of the present embodiment, comprise the heat preservation and dryness casing C with thermal-insulation heat-resistant cotton, silica gel drier H, filter I and air heater J, on the sidewall of described heat preservation and dryness casing C, be provided with carbon dioxide pipe B, heat preservation and dryness bottom half is stretched in its one end, one end is stretched out outside casing and is connected with carbon dioxide valve A in addition, the top of heat preservation and dryness casing has exhaust outlet, exhaust ports is provided with mass air flow sensor P, bottom has air inlet, exhaust outlet is connected with hot blast escape pipe E, on hot blast escape pipe, be equipped with one-way air pressurizing valve G, hot blast escape pipe between one-way air pressurizing valve G and exhaust outlet is also equipped with carbon dioxide air outlet valve F, other one end of hot blast escape pipe and silica gel drier H, filter I(prevents that the silica gel in silica gel drier from coming off, enter air heater J), air heater J and hot blast air inlet pipe L are and are linked in sequence, hot blast air inlet pipe is connected with air inlet again, air inlet place is also provided with hot blast air dispersing hood M, in hot blast air inlet pipe, be equipped with one-way air pressurizing valve K, in heat preservation and dryness casing, be also provided with and be 5 layers of stainless steel pallet D that stack up and down, the bottom of stainless steel pallet is mesh-like, be 20 order stainless (steel) wires, above every layer of pallet, be also provided with uviol lamp O, on heat preservation and dryness casing, be provided with dodge gate Q, in heat preservation and dryness casing, be also provided with the thermostat N that measures and regulate the internal temperature of heat preservation and dryness casing, this thermostat is also connected with air heater J electricity, to control air heater opening and closing.
The drying equipment of eat/medicinal/feed insect of the present invention is to use like this, to be dried Cordyceps sinensis as example: Cordyceps sinensis dry needs is laid in stainless steel pallet D, open dodge gate Q, successively stainless steel pallet is put in heat preservation and dryness casing C, close dodge gate Q, open uviol lamp O and carry out sterilization.Open carbon dioxide valve A and carbon dioxide air outlet valve F, carbon dioxide slowly enters from carbon dioxide pipe B; Because carbon dioxide is heavier than air, air will be discharged from carbon dioxide air outlet valve F, when the gas of discharging until carbon dioxide air outlet valve F can make limewash become muddy, closing carbon dioxide intake valve A, now in heat preservation and dryness casing, be full of carbon dioxide, closing carbon dioxide air outlet valve F, opening one-way air pressurizing valve K/G(forces carbon dioxide to circulate clockwise), make carbon dioxide in heat preservation and dryness casing around heat preservation and dryness casing, silica gel drier H, filter I, air heater J circulates clockwise; Regulate the pressure of air pressurized valve K/G, make carbon dioxide flow meter P stable, the airflow volume that preferably makes circulation per minute is box volume 1/10 or 1/20.Set 40~60 degrees Celsius of thermostat N target temperatures, air heater J opens, and in heat preservation and dryness casing, carbon dioxide starts to heat up, and arrives after target temperature, and thermostat N controls air heater J power supply and automatically closes; Carbon dioxide after heating is after heat preservation and dryness casing contacts with object to be dried, and the humidification of being lowered the temperature, then enters hot blast escape pipe E, by unidirectional pressurizing valve G, enter silica gel drier H, then by filter I, heater J, by unidirectional pressurizing valve K, hot blast air inlet pipe L, sees through hot blast air dispersing hood M, reenters heat preservation and dryness casing, object is dried, until Cordyceps sinensis bone dry.
