Abstract
A method for preservation of fresh food such as fresh fish by slight freeze features that an internal circulating cold air blaster in sealed insulating warehouse is used to reduce the central temp of fresh food in said warehouse to -1 - -3 deg.C, which can not damage the cells of fresh food and prolongate fresh-keeping period to more than 20 days. The method is suitable for fishing vessel and the storage and transportation of fresh food.
Description
The present invention relates to air-cooled light freezing fresh-keeping method and equipment, especially fishery products preservation method on the fishing boat and preservation by partial equipment.
Present fishing boat (referring to the medium and small ship about 10 days duty cycles), generally the fishery products preservation method of Cai Yonging is to spread ice method (0 ℃) and water-ice method (1 ℃) " to spread the ice method " and be after cleaning the good fish of reason and tiling, and sprinkles one deck and ices.Spread ice and require evenly, layer fish layer ice.Its consumption ice amount is very big, and ice and fish weight ratio are 1.5～2: 1, and freshness date is shorter, is generally about 10 days." water-ice method " is to put into ice in water, fishery products put into again, and bubble is in frozen water.Freshness date has only 3～4 days, and oppresses swelling, spoiled, fish body desquamation scratch.There was the people on the basis of water-ice method, to test afterwards.In the fresh-keeping storehouse of cryosel, seawater and fishery products is housed, be provided with cooling coil and circulating pump.Circulating pump dissolves the cryosel in the fresh-keeping storehouse, and water temperature is-1 ℃ in the storehouse.When water temperature rises, just start refrigeration machine, allow cooling coil absorb heat in the fish storehouse, make the fishery products cooling, this preservation method only can make freshness date reach 4～5 days, and fishery products become salty, and the scratch phenomenon is more serious.
The present invention is exactly freshness date in using at above-mentioned preservation method and the preservation by partial equipment ropy shortcoming of fishery products after short, fresh-keeping, and proposes a kind of air-cooled light freezing fresh-keeping method and equipment.
The invention provides a kind of air-cooled light freezing fresh-keeping method, comprising:, it is characterized in that with compressor 2 refrigeration:
A: air-cooler is installed in the fresh-keeping storehouse of sealing;
B: the cold air conduction pattern is to circulate in the fresh-keeping storehouse of sealing;
C: the fresh goods central temperature is controlled at-1 ℃～-3 ℃.
The present invention also provides a kind of air-cooled preservation by partial equipment, comprising: compressor, condenser, valve sets, (sealing insulation) fresh-keeping storehouse, evaporimeter, connect successively by pipeline between each parts, and it is characterized in that: the evaporimeter in the fresh-keeping storehouse adopts air-cooler.
Air-cooled preservation by partial of the present invention is achieved in that air-cooler is in the fresh-keeping storehouse of sealing insulation, circularly cooling in forcing, circulation cold air evenly drops to-1 ℃～-3 ℃ to the fresh goods temperature, when this temperature, the cell of fresh goods (fish) can not be damaged by frost because of the existence of juice, can not occur dewatering when dark frozen fish goods melts, fish body collapsing, fish surface drying Huang, the phenomenon of eating mouth feel difference.Also bacterial reproduction is very fast unlike spreading ice method (0 ℃), and fresh keeping time is short.
Advantage of the present invention is: cooling rate is fast, and the temperature field is even.The fishery products freshness date was more than 20 day.Fish body not damaged, eating mouth feel is good, and can make one times of fishing boat operation on the sea time lengthening, and the oil consumption that is used to come and go can be saved half, and the refrigerating fresh-keeping expense is starkly lower than other light freezing fresh-keeping methods.The present invention also can be widely used in various ships, air transport, land and other fresh-keeping warehousing.
Now in conjunction with the accompanying drawings the present invention is described in detail.
Fig. 1 is the process chart of air-cooled light freezing fresh-keeping method of the present invention and equipment
Equipment of the present invention is gone out pipe (8) and seals (insulation) fresh-keeping storehouse (9) with seawater inlet pipe (7), seawater to form by air-cooler (1), compressor (2), condenser (3), liquid storing barrel (4), valve control group (5), pipeline (6), cooling, and air-cooler is installed in the fresh-keeping storehouse (9).Air sealing and circulating in the fresh-keeping storehouse of air-cooler forced seal, so humidity does not change in the storehouse, can not make the dried Huang of fishery products in the storehouse.Air-cooled rapider and even than the calandria refrigeration.As long as wall and lower curtate have certain interval, will make the fishery products uniform decrease in temperature.
Fig. 2 .3 is the mounting vertical plane and the floor map of the air-cooled preservation by partial apparatus embodiments of fishing boat provided by the invention.Its equipment comprises: air-cooler (1), compressor (2), condenser (3), liquid storing barrel (4), valve control group (5), pipeline (6), cooling go out pipe (8), fresh-keeping storehouse (9), electric control panel (10), generating set (11) with seawater inlet pipe (7), seawater.
