Abstract

The utility model discloses a defrosting free type fruit and vegetable pre-cooling and storing fresh-keeping device. Based on the common dual circulations of cooling and storing, a water circulation system is added, which comprises a cold water storage tank, a water pump, a mixed heat exchanger, a water holding groove, etc. and an evaporator is arranged in the cold water of the cold water storage tank. When a refrigerating unit works, the temperature of the cold water in the cold water storage tank can be lowered; when the water pump works, the low temperature cold water in the cold water storage tank is transferred to the mixed heat exchanger to perform water vapour and heat transmission with the reversely flowing air, thus realizing the temperature reduction and humidification of the air. When an air blower (synchronizing with the water pump) works, the low temperature wet air can be evenly transferred to a refrigerating room to perform temperature reduction and humidification for the fruits and vegetables in the refrigerating room. The utility model can create the synchronization of refrigeration and humidification, quicken the temperature reduction speed of the pre-cooling, and lower the installed capacity. The defrosting work can be relieved, the storage ambient temperature and relative humidity are kept steady, thus being favorable for the improvement of the storage service life and storage quality, and being appropriate for the requirements of pre-cooling of fruits and vegetables in the fruit and vegetable production area of our country and the long-term storage of fruits and vegetables.

Description

The precooling of the white type fruits and vegetables of a kind of release, preservation and freshness facility
Affiliated technical field
The utility model relates to a kind of fruits and vegetables precooling, preservation and freshness facility, can exempt freezer defrosting operation, realizes that refrigeration and humidification are synchronous, improves the stability of storage environment.
Background technology
Behind the fruit and vegetable picking, as fresh and alive organism, the fluctuating range of fast precooling, the temperature that reduces cold storage environment and relative humidity is to prolong the fruit vegetables storing life-span, improves the important means of fruits and vegetables marketing quality; But present common refrigeration, air conditioned storage are as the most frequently used cold storage mode, all need its cold storage environment is carried out regular humidification, its evaporimeter is regularly defrosted, so that cause the fluctuation of envionmental humidity and reserve temperature, influence the shelf-life and the storage quality of fruits and vegetables; If defrost operation is improper, causes freezer to heat up and too highly also can produce irremediable loss the storage fruits and vegetables.
Summary of the invention
In order to overcome the deficiency that common freezer and controlled atmosphere storage need regular humidification, regularly defrost, the utility model provides a kind of fruits and vegetables precooling, preservation and freshness facility of exempting frost, this precooling, preservation and freshness facility not only can realize exempting white operation, and can realize that refrigeration and humidification are synchronous, improve the pre-cold-peace of fruits and vegetables and recovered the speed of steady temperature, and reduced the storage drying loss of fruits and vegetables.
The technical scheme that its technical problem that solves the utility model adopts is: on the basis of common refrigeration two circulations (cold-producing medium circulation and cold air circulation), increase by a cover water circulation system, comprise equipment such as cold-storage water tank, water pump, mixed heat exchanger, water receiving tank, and evaporimeter is placed the cold water of cold-storage water tank.Can reduce the cold water temperature in the cold-storage water tank during refrigeration unit work; Low-temperature cold water in the cold-storage water tank can be delivered in the mixed heat exchanger during pump working, be carried out aqueous vapor and heat transmission, realize the decreasing temperature and increasing humidity of air with the air of reverse flow; The low temperature humid air evenly can be delivered in the refrigerator during blower fan (synchronous) work, the fruits and vegetables in the refrigerator are carried out cooling moisture-retaining with pump working.Owing to be that the low temperature humid air flows at fruit and vegetable surfaces, not only can reduce the respiration of fruits and vegetables fast, and the transpiration of fruits and vegetables is also had fine inhibitory action, be fit to very much the pre-cold-peace Long-term Storage of fruits and vegetables.After increasing water circulation system, evaporimeter is placed in the cold-storage water tank, does not have the defrosting problem, simplified control helps the stable of temperature and relative humidity between Keep cool.
The beneficial effects of the utility model are: can exempt freezer defrosting operation, realize that refrigeration and humidification are synchronous, improve the stability of storage environment, simplify the operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a fundamental diagram of the present utility model.
1. refrigeration unit among the figure, 2. evaporimeter, 3. cold-storage water tank, 4. water pump, 5. water supply pipeline, 6. water-locator, 7. water receiving tank, 8. water return pipeline, 9. mixed heat exchanger, 10. filler, 11. air intake vents, 12. blower fans, 13. air outlets, 14. refrigerators.
The specific embodiment
In Fig. 1, refrigeration unit 1 and evaporimeter 2 have been formed the cold-producing medium circulation, refrigeration unit 1 work changes cold-producing medium into the low-temp low-pressure liquid condition and delivers in the evaporimeter 2, liquid refrigerant is endothermic gasification in evaporimeter 2, and then enter refrigeration unit 1, realize the purpose of cold-storage water tank 3 inner cold waters cooling.
Low-temperature cold water in the cold-storage water tank 3 is delivered to above the filler 10 through water pump 4, watering pipeline 5, water-locator 6, evenly flows down from filler 10 internal voids then, collects at last in the water leg 7, again in water return pipeline 8 flow back into cold-storage water tank 3.
Air in the refrigerator 14 is sucked by the air intake vent 11 of blower fan 12 from mixed heat exchanger 9 rear sides, internal void through filler 10 upwards flows again, heat, wet (matter) exchange take place with top-down cold water, realize decreasing temperature and increasing humidity, blow in the refrigerator 14 by air outlet 13 at last, the fruits and vegetables in the refrigerator 14 are carried out cooling moisture-retaining.
