Abstract
The present invention relates to an equipment for drying green material at low temp. and its processing method. Said equipment comprises electric heater, heat-conducting oil, heat transferring work medium, cylinder, circulating tube and temp. control tube. Its drying process includes the steps: loosing green material, tying small bunch, closing end, placing the end-closed small bunch of green material into the electric heater which is preheated to 50 deg.C, evacuating cylinder, dewatering and stoving.
Description
Technical field:
The present invention relates to a kind of process, particularly a kind of equipment of low temperature drying green material and processing method thereof.
Background technology:
At present, the oven dry of green materials such as green grass and green vegetables has many kinds, as natural oven dry, hyperthermia drying etc.Naturally oven dry needs the plenty of time, is not easy to production operation, the general degree more than 100 ℃ of hyperthermia drying, and it is yellow to cause green vegetables, green grass to do, and destroys nutritional labeling.Taked a kind of cryogenic freezing furnace drying method in recent years abroad, guaranteed primary colors, the original flavor of green material, not oxidation, the nutrition of not running off.But this kind apparatus expensive yields poorly, and the scope of application is little, can't solve the oven dry problem of aquaculture greenfeed in enormous quantities at all, has only by the time just can dry, store after the maturations such as green grass, corn stalk.Like this, can't solve clover grass (cutting every year three times), corn stalk is dried storage in high vegetative growth phase.Utilize this method to carry out the green material oven dry, cause green material oxidation flavescence again, lignin increases hardening, can't do pig, chicken, the edible feed of fish, even make feed for ox, sheep, horse, nutrition is also run off seriously, more can't solve green material is become flour, become pig, chicken feed.Even pulverize, because oxidation flavescence hardening can't be used as pig, chicken, fish meal.Cross the burring drying plant, can only dry semiarid, employing be the oven dry of the high-power hot blast of heat boiler stream, power consumption is big, can not move, the scope of application is little, poor quality, the cost height, the equipment price height influences its development speed.
The content of invention:
The objective of the invention is to propose a kind of vacuum heat superconducting tech equipment and come the low temperature drying green material, make green material have more nutrition, dry run is short, the easier processing of equipment.
Technical scheme of the present invention comprises:
This drying plant includes electric heater, conduction oil, heating agent working medium, tank body and circulation pipe, temperature controller is characterized in that described electric heater is contained in the cavity that is marked with conduction oil, the cavity covering is equipped with heating agent working medium and is sealed shape and places the tank body outer bottom, and is communicated with heating agent working medium circulation pipe; Be equiped with exhaust tube with holes and heating agent working medium circulation pipe in the tank body, its exhaust tube links to each other with the outer vavuum pump of jar, is provided with temperature controller in the bottom of tank body, and the bottom also is provided with the haul track in tank body, and whole tank body is cavity-like, is provided with the folding end socket at the two ends of tank body.
This stoving process is: with the loose wisp of beating of green material, put into the electric heater of 50 ℃ of preheatings then through end socket.The state of vacuumizing in the jar is carried out green material dehydration, oven dry, and about 2 hours, again by the discharging of other end end socket, going round and beginning again began to carry out green material oven dry operation.
The present invention has embodied the characteristics of green material chance air oxidation, has adopted vacuum technique; At with the high problem of boiler hot-air seasoning power consumption, adopted heat superconducting tech, low temperature drying under vacuum condition; Can only factory dry problem at past equipment, adopt miniature movable type equipment, the field can be dried, and has remedied the large equipment deficiency.This equipment can keep primary colors, original flavor, the former nutritional labeling of green material, can reach zero moisture, does not stick with paste not burntly, is difficult for catching fire, and convenient processing is processed into flour as pig, chicken, fish meal to green grass, straw, can drop to safe moisture and store.This new equipment is owing to adopt hot superconduction cryogenic vacuum negative pressure oven dry, energy consumption greatly, thus reduced energy consumption.Owing to cancelled original boiler, air-heater, air-cooler, heat exchanger, mechanical conveyor, reduced the drying plant cost significantly.
This equipment can be dried the green material of 70-60% high-moisture, and green materials such as the green grass in any growth period, green vegetables, sapphire rice straw and various straw kind, careless class, seedling class can be dried zero moisture, and water content can full-automatic computer control.
This equipment formula that can fix also can be made movable type.
The feeding intake how many visual device size of this technical process and deciding, for ease of oven dry, before the green material oven dry, break into very loose bundle shape, utilize the economize on electricity rapid heater, preheating conduction oil, conduction oil heat superconducting fluid again, and heating agent working medium flash heat transfer reaches the requirement temperature to entire equipment, green material is heated to about 50 degrees centigrade, and 2 hours then through the end socket discharging.The inner cell spiracle of green grass is opened, be drawn out of externally rapidly, under cryogenic conditions, utilize vavuum pump to extract dehydration out, reached not oxidation of green material under cryogenic vacuum, rapidly the purpose of oven dry.
Description of drawings:
Accompanying drawing 1 of the present invention is the device structure schematic diagram;
Accompanying drawing 2 of the present invention is the A-A cutaway view of device structure schematic diagram.
The specific embodiment:
Equipment of the present invention is the pot type structure, also can make other shape, but configuration state is constant, electric heater 1 can be provided with a plurality of in the jar bottom, be contained in the heat conduction oil groove 2, the outer enclosure of oil groove has both heating agent working medium 3 of superconducting fluid, this heating agent working medium 3 is pipe in circulation pipe 4 and jar, jar interlayer cavity communicates, tank body 6 is placed on the bearing 7, tank body inner bag and bottom are provided with material track 8, conduction oil slot cavity body 9 can be established two, and whole cavity and tank body seat are on a seat board 10, and vavuum pump 11 communicates with exhaust tube 12 with holes, the two ends of tank body are provided with folding end socket 13, be used for input and output material, be divided into two supplies rooms 14 in the whole tank body, outside tank body, also be provided with switch board 15 and control power supply, and vavuum pump, temperature controller 16 etc.
