Abstract
The invention discloses a liquid state fluid cryogenic quick-freezing farm product process, which takes fresh farm products as raw materials and prepares quick-frozen products of the fresh farm products by the steps of primary selection, pretreatment, cleaning, finish machining, vacuum packaging and liquid state freezing. The process in the invention has the advantages of convenient operation, energy conservation, high production efficiency, and safety and sanitation.
Description
Technical field:
The present invention relates generally to a kind of liquid state fluid cryogenic quick-freezing farm product process.
Background technology:
At present, domestic cryogenic quick-freezing to agricultural product all is to adopt air-cooled quick freezing, the unsuitable quick-frozen bulk of air-cooled quick-frozen footpath agricultural product, and also air-cooled quick freezing makes the dehydration of agricultural product surface portion and cause the mouthfeel of agricultural product and nutrition to cause disappearance.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art, the liquid state fluid cryogenic quick-freezing farm product process of a kind of production efficiency height, energy savings to be provided.
The present invention is achieved by the following technical solutions:
A kind of liquid state fluid cryogenic quick-freezing farm product process is characterized in that: with fresh agricultural product is raw material, carries out according to the following steps successively:
A. primary election: reject bad agricultural product and the impurity of quality;
B. preliminary treatment: the agricultural product of primary election are removed the peel as required shelling;
C. clean: with pretreated agricultural product, water cleans up;
D. fine finishining: the agricultural product that will clean drain, and cut as required or put in order;
E. vacuum-packed: with the agricultural product after the fine finishining, Package size as required carries out vacuum packaging;
F. liquid freezing: the agricultural product bag that vacuum packet is installed places the freezing liquid quick-frozen 15min-35min that circulates, and described chilled liquid temperature is at-35 ℃--and 60 ℃.
Described a kind of liquid state fluid cryogenic quick-freezing farm product process is characterized in that: described freezing liquid is one or more the compositional liquor in ethanol, propane diols and the glycerine.
Described a kind of liquid state fluid cryogenic quick-freezing farm product process is characterized in that: described agricultural product are edible fungi, water bamboo shoot class, fiddlehead class, beans, corn class, Chinese chestnut class, meat poultry or fish and shrimp agricultural product.
Liquid state fluid cryogenic quick-freezing is that agricultural product use nontoxic, harmless, free from corrosion cold (carrier)-cold flow liquid recycle stream moving in airtight system, carries out quick frozen product under lower temperature (35 ℃--60 ℃).
Liquid state fluid cryogenic quick-freezing in developed country such as American-European-Japanese now just towards more low temperature (being lower than-60 ℃) automaticity is higher, the equipment freezing liquid of automatic feed/discharge and the two-way reverse flow of material, and corresponding freezing liquid is used safely in food directions such as higher plant of freezing value and agricultural product and studies.Liquid state fluid cryogenic quick-freezing is as a fresh-keeping freezing importance, to bulk footpath freshness high request below-35 ℃, snap frozen freshness height, health, safety are saved the advantage that this aspect has other freezing methods to be difficult to substitute that is frozen into more.
Advantage of the present invention is:
1, the cryogenic quick-freezing time fast, fresh-keeping good, the space is little, under cryogenic conditions, the freezing liquid that in airtight system, circulates (cold carrier), it is minimum that cold consumption is dropped to, avoid the required production line length of Flow of Goods and Materials, the space is big, the problem that the device fabrication expense is big.And under very big temperature difference motive force (when normal agricultural product temperature is 15 ℃, the temperature difference reaches 50 ℃-70 ℃) make the quick-frozen time shorter, speed is faster, avoided freezing slowly cavityization or bulk footpath agricultural product (material) core and be difficult to deep colling and it formed stab out cell membrane than megacryst and cause cell liquid to run off and produce the disorganize structure, color and luster, mouthfeel change or problems such as nutritional deficiency.
2, good freezing liquid has low viscosity, and low adhesive force has good flowability at low temperatures, and, have nontoxic, harmless, do not have corrosion and edible characteristics, easily obtain at home and cheap, more economical in the use, safer, much cleaner.
3, make full use of in intrasystem cold and the heat system frost-free and do not freeze, casing and case lid do not freeze and freeze, and improve usefulness to greatest extent, save the energy, and energy consumption is low, and for the little agricultural product of sheet type or volume that rub, the energy that is consumed is half of air-cooled quick-frozen.But the agricultural product (diameter is greater than 500mm) in quick-frozen bulk footpath.Vacuum-packed laggard scanning frequency is frozen, and is much cleaner, do not make the agricultural product dehydration.
Description of drawings:
Fig. 1 is a flow chart of the present invention.
The specific embodiment:
Embodiment 1
The bad mushroom of quality is removed in screening, rejects the impurity of mushroom root, cleans up with clear water, places on the screen cloth to drain, and obtains mushroom product 60kg, is divided into each packing 1kg, vacuum packaging.The product bag that vacuum packet is installed places-30 ℃ of freezing liquid quick-frozen 20min that circulate, and obtains the good mushroom product of quick-frozen.
Embodiment 2
Remove the bad fresh and alive lobster of quality; Slough the shrimp shell and keep peeled shrimp, clean up, place on the screen cloth to drain, get lobster tail product 300kg, be divided into each packing 2kg, vacuum packaging with clear water.The product bag that vacuum packet is installed places-45 ℃ of freezing liquid device quick-frozen 25min that circulate, and obtains the good lobster tail product of quick-frozen.
Embodiment 3
The bad fresh bamboo shoots of quality is removed in screening; Slough crust, clean up, place on the screen cloth to drain, cut into the shape that needs, get bamboo shoots product 360kg, be divided into each packing 2kg, vacuum packaging with clear water.The product bag that vacuum packet is installed places-55 ℃ of freezing liquid device quick-frozen 25min that circulate, and obtains the good bamboo shoots product of quick-frozen.
