Referring to Fig.1~Fig. 4, this is the embodiments of the present invention a1, specifically:

A kind of air heat source and thermal pump betel nut drying system, including drying room 1 and heat pump machine 2, the heat pump machine are interior equipped with cold Matchmaker's compressor 21, the cold medium compressor is equipped with refrigerant inlet 211 and refrigerant exit 212, between refrigerant exit and refrigerant inlet It is connected in turn: condenser 22, fluid reservoir 23, filter 24, expansion valve 25, evaporator 26, gas-liquid separator 27, the refrigerant Compressor, fluid reservoir, filter, expansion valve, evaporator and gas-liquid separator are each provided at the left side of the drying room, the condensation Device is located at the right side of the drying room, and the evaporator is equipped with sucking blower 261, and sucking blower is inhaled by the rotation of fan blade Enter the air around heat pump machine, so that outside air is drawn into the right on the evaporator.The gas-liquid separator is equipped with liquid Refluxing opening 271, liquid reflux mouth are equipped with liquid return tube 272, gas-liquid separator and the fluid reservoir and are returned by the liquid Flow tube is connected to, so that being recycled in the refrigerant not gasified sufficiently that evaporator comes out.

The right side inner wall of the drying room is equipped with conveying gas blower 3, and the wind direction of supplying gas of conveying gas blower is directed toward a left side for drying room Side, the middle part of the drying room are equipped with rack 4 with multi-layer structure, and the rack is horizontal positioned, and neatly tiling is put on rack It is equipped with betel nut to be dried.Vapor can be evaporated when being oven-dried due to betel nut, in order to avoid rack gets rusty, the rack is not by Rust Steel material is made, and the heat that the condenser is distributed is blowed to the rack by the conveying gas blower.

Referring to Fig. 3 and Fig. 4, it is additionally provided with vertical partition 5 in the heat pump machine, the partition is located at the right side of the evaporator Side, partition have a hollow cavity, and the bottom of partition is equipped with drain port 51, and the lower section of drain port is equipped with collecting box, on the partition It is additionally provided with the ventilation hole 52 of multiple matrix distributions, is equipped with vertical water collection sheet 53 in the hollow cavity.Since refrigerant flows through institute Endothermic gasification when stating evaporator, therefore the temperature near evaporator is lower than environment temperature, when the sucking blower will dry After indoor damp-heat air is drawn into the evaporator from left to right, the law level energy in damp-heat air is absorbed by refrigerant；By It is in the right side of evaporator in partition, therefore the temperature of partition is lower than environment temperature, the vapor in the damp-heat air is logical It is intercepted after crossing the ventilation hole of partition by the water collection sheet, vapor condenses into droplet on water collection sheet, and the droplet is in gravity Effect collect down and be flowed into the collecting box from the drain port of partition.

Using the above structure, the utility model has the beneficial effects that the utility model dries betel nut using heat pump machine, Liquidation exothermic reaction dries betel nut when heat pump machine mainly flows through condenser by the refrigerant of high-temperature gasification, and heat pump machine can inhale It receives the law level energy of damp-heat air in drying room and indoor Water vapor condensation collection will be dried, therefore the drying efficiency of heat pump machine It is higher than traditional stoving process, and the utility model does not need ventilation setting and can coagulate to indoor vapor is dried Knot is collected, avoid as ventilation and caused by energy loss, saved a large amount of social resources.

In order to accurately control the indoor temperature of drying, thermal switch 6, thermal switch are equipped in the drying room It is electrically connected with the cold medium compressor, the drying room is externally provided with thermoregulator 61, and the thermoregulator can be set The temperature sensor value of thermal switch, user can according to actual demand by the thermoregulator come set temperature sense The temperature sensor value of inductive switch, when the temperature sensor value of thermal switch is more than preset value, the cold medium compressor is short It taps into standby mode, the sucking blower continues to work at this time；When the temperature sensor value of thermal switch is lower than default When value, the cold medium compressor enters working condition.

Referring to Fig. 2, working principle of the utility model is: the cold medium compressor in the heat pump machine will come in from refrigerant inlet The gaseous coolant of Room-temperature low-pressure be compressed into the gaseous coolant of high temperature and pressure, the gaseous coolant of the high temperature and pressure is from refrigerant exit Outflow, liquidation exothermic reaction becomes the liquid refrigerants of normal temperature high voltage, institute when the gaseous coolant of the high temperature and pressure flows through the condenser Heat of the condenser by cooling medium liquefaction heat release when is stated to be dispersed into drying room；The liquid refrigerants of the normal temperature high voltage passes through fluid reservoir After filter, initially enter the expansion valve, due to expansion valve can change throttling section or chock length reach control it is cold The flow of matchmaker, therefore the liquid refrigerants of the normal temperature high voltage flows through the liquid refrigerants that can become low-temp low-pressure after the expansion valve, The law level energy of damp-heat air in drying room is absorbed when the liquid refrigerants of the low-temp low-pressure flows through the evaporator and is steamed Hair, after the effect of evaporator, the liquid refrigerants of the low-temp low-pressure can become the gaseous coolant of Room-temperature low-pressure, described damp and hot Vapor in air condenses into droplet on the water collection sheet and is flowed into the collecting box, what fraction did not gasified sufficiently Liquid refrigerants can be recovered in the fluid reservoir by the gas-liquid separator, and the gaseous coolant of the Room-temperature low-pressure is again into from described Refrigerant inlet enters in cold medium compressor, constantly repeats the above process, and reaches preset value until drying indoor temperature.

The process flow that betel nut is dried in the utility model:

1, fresh betel nut is neatly tiled and is placed on the rack of drying room, betel nut water content at this time is higher, needs The temperature of drying room is stepped up near 70 DEG C, the preliminary drying stage of betel nut maintains daily 20~24 hours, continue 1~ 2 days；

2, it in order to guarantee that betel nut drying rate is uniform, needs to screen betel nut, sub-elects big fruit and fruitlet, by big fruit It is placed on the bottom of rack；

3, the temperature of drying room is stepped up near 70 DEG C, the secondary drying stage of betel nut continues 20~24 hours；

4, the temperature of drying room is down between 50~55 DEG C, the final drying stage of betel nut continues two days, so that drying The weight of betel nut afterwards is equivalent to the 25~30% of the weight of fresh betel nut.

The better embodiment of the utility model is illustrated above, but the utility model be not limited to it is described Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention Type or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
