Abstract
The invention belongs to the field of agriculture and agricultural product deep processing and discloses a method for drying granular materials through a heat pump. The method relates to an industrial application. The method consists of a heat pump drying and dehumidifying unit 1, a drying chamber 2, a low-speed multi-layer stacked type material spreading and conveying belt mechanism 3, slant material guide plates 4, tooth-shaped material mixers 5 and a rotary wind-isolation distributor 6. According to the method, a drying method of continuous feeding and continuous discharging is adopted, so that drying processes for to-be-dried materials of the same batch in the drying chamber are identical, and the consistency of the moisture content of finished products of dry granular agricultural products is guaranteed.
Description
Technical field
The invention belongs to agricultural and field of deep processing of farm products, disclose a kind of method of the heat pump drying granular material that relates to industrialization purposes.
Background technology
In Processing Farm Produce, heat pump techniques is used in drying of wood field both at home and abroad.Heat pump is also for the dry materials of food processing industry, but mainly lays particular emphasis on aquatic products, fowl poultry kind product (protein, fat more) and greengrocery product (high-moisture percentage) is dry.Heat pump drying unit is all to take wind as moisture transmitting medium when dried material at present, in service intermittent mode, the material to be dried of same batch is sent into hothouse simultaneously, discharging simultaneously after dry end.Because heat pump drying unit operating temperature is lower, cause drying time longer, therefore material to be dried hangs or fixedly hold state in fixing in hothouse.Be dried and by air inlet, be blown into hothouse with wind, after moisture absorption, from air outlet, leave hothouse, the wind of air inlet is drier, and the wind of air outlet is moister, causes same batch of finished product inconsistent apart from air inlet distance, and the inconsistent phenomenon of moisture content.External processing method is that inlet and outlet is switched in turn, and finished product water ratio uniformity makes moderate progress, but from air port apart from difference, finished product moisture content or different.
Summary of the invention
The present invention by heat pump drying dehumidifying unit 1, hothouse 2, low speed laminated multi-layer formula material pave belt conveyor mechanism 3, oblique stock guide 4, tusk feed mixer 5, rotaryly every wind distributing device 6, form.
The object of the invention is for solving heat pump drying device dried particles shape agricultural product finished product moisture content non-uniformity problem.
The object of the invention is to reach by following measure: heat pump drying dehumidifying unit 1 is for being dried the circulated air after moisture absorption.Rotary every wind distributing device 6 for material to be dried being sent into continuously to hothouse 2, being cut off contacting of hothouse gas and outdoor air, and material to be dried be distributed to low speed laminated multi-layer formula material equably pave in belt conveyor mechanism 3.Low speed laminated multi-layer formula material paves belt conveyor mechanism 3 for launching material to be dried, increases material to be dried surface area, to improve the evaporation capacity of moisture, and mobile material to be dried.The bounce-back jumping phenomena producing while being fallen to lower floor by upper strata for the material that prevents from paving in belt conveyor mechanism 3 at low speed laminated multi-layer formula material, is provided with oblique stock guide 4.For increase the material order change frequency of arranging in dry run, at low speed laminated multi-layer formula material belt conveyor mechanism 3 upper surfaces that pave, be provided with the tusk feed mixers 5 of many group mutual dislocation, increase moist material and translated into surperficial number of times by bottom.
Accompanying drawing explanation

The specific embodiment
Material to be dried is rotary enters hothouse 2 continuously every wind distributing device 6, and material to be dried is distributed to low speed laminated multi-layer formula material equably paves in belt conveyor mechanism 3.By heat pump drying dehumidifying unit 1 dry wind out, be parallel to the low speed laminated multi-layer formula material belt conveyor mechanism 3 that paves and blow over material to be dried surface, after moisture absorption, leave hothouse, enter heat pump drying dehumidifying unit 1, heat pump drying dehumidifying unit 1 is removed after the moisture in circulated air, drier wind is recycled.Material to be dried paves the ground floor of belt conveyor mechanism 3 after dry a period of time at low speed laminated multi-layer formula material, superficial layer has lost moisture content, is moved and drops into the second layer, and the material order of arranging changes, moist material has been translated into surface, falls after drying the 3rd layer again; After repeatedly upset is dried, the moisture content of material reaches product requirement by outfeed belt conveyor output hothouse.Oblique stock guide 4 has suppressed the bounce-back jumping phenomena producing when material that low speed laminated multi-layer formula material paves in belt conveyor mechanism 3 is fallen to lower floor by upper strata, reduced the loss of material in dry run, and reduced low speed laminated multi-layer formula material belt conveyor mechanism 3 appearance and sizes that pave, dwindled the overall dimensions of hothouse.For increase the material order change frequency of arranging in dry run, at low speed laminated multi-layer formula material belt conveyor mechanism 3 upper surfaces that pave, be provided with the tusk feed mixers 5 of many group mutual dislocation, making moist material in dry run, translate into surperficial number of times increases, the evaporation capacity that has improved moisture, has reduced drying time.
In the present invention, owing to having adopted the dry working method of continuous feed and continuous discharge, it is identical making the dry run experiencing in hothouse with batch material to be dried, has guaranteed dried particles shape agricultural product finished product moisture content uniformity.
