Description
Technical field
The utility model relates to a kind of fruits and vegetables differential pressure precooling storehouse, relates to a kind of differential precooling of fruits and vegetables storehouse with high humidity function specifically.
Background technology
Fruits and vegetables precooling mode mainly contains vacuum pre-cooling, differential pressure precooling, forced ventilation precooling, cold water precooling and ice precooling.Vacuum pre-cooling only is applicable to the leaf vegetables precooling, is not suitable for fruit vegetables such as tomato, cucumber etc., more is not suitable for the fruit precooling; Its precooling speed is very fast; Just can reach the precooling target temperature in general 30 minutes, but need supporting heat room, percentage of water loss is about 3% behind the vegetable precooling.The cold water precooling is suitable for the root vegetable precooling, like vegetables such as carrot, radish, potato, corns, but both precoolings, can also reach the purpose of cleaning, but it is few to be suitable for vegetable species, especially is inappropriate for the leaf vegetables precooling.The ice precooling is only applicable to flower vegetables such as broccoli and cauliflower.And differential pressure precooling and the nearly all vegetables of forced ventilation precooling and fruit can precoolings, but forced ventilation precooling cooling velocity is slow, inhomogeneous, and the general precooling time needed more than 24 hours, and percentage of water loss reaches 4% after the fruits and vegetables precooling, has had a strong impact on the quality of fruits and vegetables; The precooling of suitable various vegetables of pressure reduction ventilation precooling and fruit; Fast 2～10 times of cooling velocities than forced ventilation precooling; The general precooling time that only needs 2～6 hours, precooling is even, but its percentage of water loss still reaches about 2%; Influence outward appearance after the precooling of leaf vegetables, and operating technology is had relatively high expectations during the fruits and vegetables precooling.
The utility model content
For overcoming above-mentioned defective, that the utility model aims to provide is a kind of both easy to operate, precooling efficient is higher, simultaneously the extremely low differential pressure precooling storehouse of fruits and vegetables percentage of water loss after precooling.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of fruits and vegetables differential pressure precooling storehouse comprises the storehouse body; Top in the body of said storehouse is provided with air-cooler, and the said air-cooler compressor bank external with being arranged on the storehouse is connected pipeline through cold-producing medium and is connected, and also is provided with a pressure reduction ventilation unit in the body of said storehouse; Said pressure reduction ventilation unit comprises static pressure casing and blower fan; The place ahead of said static pressure casing is provided with air outlet, and the side of said static pressure casing is provided with air inlet, and said blower fan places the air opening end of static pressure casing; Also be provided with atomizing humidifier in the said static pressure casing, the below of said static pressure casing is provided with drip pan.
Also be provided with the porous wet film in the said pressure reduction ventilation unit, said porous wet film places between blower fan and the atomizing humidifier.
Also be provided with water level controller in the said drip pan.
Adopted the fruits and vegetables differential pressure precooling storehouse of the utility model; Owing on traditional basis, fruits and vegetables precooling storehouse, increased the pressure reduction ventilation unit; The water smoke that produces through the atomizing humidifier on the pressure reduction ventilation unit mixes formation high humidity Cryogenic air with the Cryogenic air that air-cooler produces; Relative humidity in the precooling storehouse is improved greatly, cause being cooled the serious problem of fruits and vegetables drying loss dehydration in the conventional fruits and vegetables precooling process thereby thoroughly solved, the fruits and vegetables percentage of water loss can be reduced to below 1%; Outward appearance, quality and the freshness of fruits and vegetables have been guaranteed, for fruits and vegetables place of production precooling freshness retaining provides basic equipment guarantee.Simultaneously; Circulation high humidity Cryogenic air attaches the part heat that in evaporation process, also can take away fruits and vegetables at the moisture film of fruit and vegetable surfaces when directly cooling off fruits and vegetables, make whole precooling process more efficient; Obviously improved the precooling effect of fruits and vegetables, precooling speed is 2～10 times of common precooling storehouse.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-storehouse body, the 2-air-cooler, the 3-compressor bank, the 4-cold-producing medium connects pipeline, 5-pressure reduction ventilation unit, 6-static pressure casing, 7-blower fan, 8-air outlet, 9-air inlet, 10-atomizing humidifier, 11-drip pan, 12-porous wet film, 13-water level controller.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of fruits and vegetables pressure reduction freezer, comprise storehouse body 1; Top in the said storehouse body 1 is provided with air-cooler 2; Said air-cooler 2 compressor bank 3 outer with being arranged on storehouse body 1 is connected pipeline 4 through cold-producing medium and is connected, and the cooperation through compressor bank 3 and air-cooler 2 produces Cryogenic air, can carry out precooling to storehouse body 1 interior fruits and vegetables; In sum, with existing fruits and vegetables precooling storehouse basically identical.
The innovative point in the fruits and vegetables differential pressure precooling storehouse of the utility model mainly is also to be provided with in the said storehouse body 1 a pressure reduction ventilation unit 5; Said pressure reduction ventilation unit 5 comprises static pressure casing 6 and blower fan 7; The place ahead of said static pressure casing 6 is provided with air outlet 8, and the side of said static pressure casing 6 is provided with air inlet 9, and said blower fan 7 places air outlet 8 ends of static pressure casing 6; Also be provided with atomizing humidifier 10 in the said static pressure casing 6, the below of said static pressure casing 6 is provided with drip pan 11.Water smoke through 10 generations of the atomizing humidifier in the pressure reduction ventilation unit 5; Be mixed in the Cryogenic air of air-cooler 2 generations, form a kind of high humidity Cryogenic air, in fruits and vegetables precooling storehouse, create the environment of a highly humid air circulation; Relative humidity in the fruits and vegetables differential pressure precooling storehouse is improved greatly; Cause being cooled the serious problem of fruits and vegetables drying loss dehydration in the cooling procedure of conventional fruits and vegetables precooling storehouse thereby thoroughly solved, simultaneously, circulation high humidity Cryogenic air is when directly cooling off fruits and vegetables; Attach the part heat that in evaporation process, also can take away fruits and vegetables at the moisture film of fruit and vegetable surfaces, make whole precooling process more efficient.
