Description

Dual system agricultural product drying dehumidifying two effect devices
Technical field
The utility model relates to processing of farm products field, especially dual system agricultural product drying dehumidifying two effect devices.
Background technology
Heat pump dryer is to utilize contrary Carnot's principle, absorbs the heat of baking room outer air and transfers in baking room, and the temperature that realizes baking room improves, and coordinates corresponding equipment to realize the dry of material.In the course of work, evaporator with heat pump absorbs the heat in outside air, or the waste heat of exhaust in recovery dry run, through compressor work, by energy carrying (transfer), to baking room, the hot-air in baking room is heated through iterative cycles, absorb the moisture in material, and the process of process hot air dehumidifying or condensed water outlet, the moisture in material is discharged, finally realize the continuous drying of material.
According to hydrofuge mode difference, can be divided into two types, hot-air seasoning type and dehumidifying drying type.
Hot-air seasoning type, its operation principle is: heat pump cryogenic vaporizer absorbs the heat of baking room outer air and transfers in baking room, air heat in baking room is heated up, the hot air circulate material of flowing through, absorb the moisture in material, the hot-air of high humidity is discharged outside baking room via wet-emitting blower, finally realizes the continuous drying of material.
Its advantage is: 1, can absorb baking room outside air heat, programming rate is fast, and can heat up and maintain higher bake out temperature, and rate of drying is fast; 2, in drying course, bake out temperature, humidity are separately controlled, and temperature is controlled and realized by the start/stop of compressor of dryer, and humidity is controlled and realized by wet-emitting blower start and stop, can realize humiture and accurately control.But its shortcoming is that, in hydrofuge process, humid air can be taken away heat, from the external world, introduce new wind also needs consumption of calorie and brings new humidity load into simultaneously, so be subject to the impact of environment temperature and humidity larger, environment temperature is lower, humidity is higher, and thermal loss is larger.
Dehumidifying drying type, its operation principle is: heat pump cryogenic vaporizer is down to the air themperature of flowing through below dew-point temperature, makes air separate out moisture (condensed water is discharged outside baking room by drainpipe), absolute humidity reduction; Recycling heat pump condenser adds hot-air, improves air themperature, reduces relative humidity, produces the dry air of high temperature low humidity, and the dry air material web of flowing through is walked moisture and again got back to evaporimeter, forms drying cycles.Through after drying cycles repeatedly, complete dry materials operation.
Its advantage is: drying medium (air) seals completely at drying course, and condensate water discharge process thermal loss is few, need to from the external world, not introduce new wind, is subject to the impact of environment temperature very little.But its shortcoming is: 1, in dehumidification by condensation process, need to lower the temperature and make hydrogenesis discharge, can consumption of calorie, programming rate is slow, finally can reach and holding temperature lower; 2, when drying medium (air) relative humidity is very low, dehumidification rate is very low, and most of cold is used for the cooling of drying medium, rather than for dehumidifying, does not even have hydrogenesis to separate out; 3, in drying course, bake out temperature, humidity realize by the start/stop of compressor of dryer, are difficult to realize humiture and accurately control.
