Description
Technical field
The present invention relates to quick-freezing plant, specifically a kind of quick-freezing plant of aquatic products.
Background technology
Aquatic products freezing refers to suppress the active numerous with attached microbial of aquatic products autolysis enzyme using cryogenic conditions
Grow, and slow down the chemical reaction velocities such as its lipid oxidation, nonenzymatic browning, be allowed to that in storage period the low of fine quality can be kept
Temperature fresh-keeping method.Aquatic products freezing generally comprises cold storing and fresh-keeping and freezes fresh-keeping two classes method, is mainly wherein freezing fresh-keeping method
Aquatic products are carried out by freezing equipment quick-frozen.It is larger to there is iuntercellular ice crystal growing amount in present aquatic products freezing, intracellular
Analysed excessively outside moisture, juice loss is more when causing to thaw, the problem of making the elasticity reduction of aquatic products, taste bad.
Prior art such as Authorization Notice No. is CN104823008B Chinese invention patent, discloses a kind of feature continuous
Quick-freezing plant, is integrally in contact in which can make cold airflow exhaustive with being frozen the surface of thing, easily passes through maximum ice knot as early as possible
Crystalline substance generation band, defined temperature can be reached in a short time by being frozen the central part of thing, and the continuous quick-freezing plant of feature possesses
Collecting is frozen thing（Q）Refrigerating chamber（2）, in the refrigerating chamber（2）Central portion arranged, by refrigerating chamber with separating wall-like（2）Point
Area freezes subregion into the 1st（2a）With the 2nd freezing subregion（2b）Leng but use Re Jiao Change devices（1）, subregion is freezed across the 1st（2a）With
Leng but uses Re Jiao Change devices（1）For the 1st Air Blast fan arranged in face of shape（5）, and across the 2nd freezing subregion（2b）Used with cooling
Re Jiao Change devices（1）For the 2nd Air Blast fan arranged in face of shape（6）.The device, which can make to be frozen thing, to be cooled uniformly, but device inwall
Freeze serious, energy waste is easily caused, while being frozen the icing conditions on thing surface than more serious.
The content of the invention
It is an object of the invention to provide one kind aquatic products chilling rate can be made fast, iuntercellular ice crystal is few, be cooled uniform,
Device inwall is difficult the quick-freezing plant of the aquatic products of icing.
The present invention is directed to the problem of being mentioned in background technology, and the technical scheme taken is：A kind of quick-freezing plant of aquatic products,
The blowing fan that shape is arranged is faced including heat exchanger for cooling and with heat exchanger for cooling；Heat exchanger for cooling is with partition wall
Shape is arranged, and refrigerating chamber is divided into the first freezing subregion and the second freezing subregion, and the another side of the first freezing subregion sets first to send
Wind fan, the another side of the second freezing subregion sets the second Air Blast fan, and the first Air Blast fan and the second Air Blast fan are and wind
Fan control unit connection；Cold air is circulated by returning to stream in refrigerating chamber；Stacked in refrigerating chamber and be frozen thing.Cooling heat
Exchanger is for the refrigerant pipe or multiple radiating fins and refrigerant flow path with snake shape or ladder-shaped or with cold air
With the bulk shape of perforation.Return to the width of stream：Refrigerating chamber width is 1:10~15.It is frozen the stacking of thing and is highly less than and send
1.0 ~ 1.2 times of wind fan height.Be frozen thing stacks 1.0 ~ 1.2 times that width is less than Air Blast fan height.Present invention dress
Put middle cold air can comprehensive contact be frozen thing, temperature drop quickly, breaks through zone of maximum ice crystal formation in the short time, cold
The core for freezing thing reaches the temperature of setting in a short time；Inside cell tissue concentration solute and food tissue, colloid with
And the time that various composition contacts with each other is short, the injury of concentration drops to very low, and few, juice loss during defrosting is analysed outside ICW
Few, the mouthfeel of aquatic products is Fresh ＆ Tender in Texture flexible close to fresh goods after defrosting.
Preferably, the inwall of refrigerating chamber 2 has ice-covering-proof coating, composition and its parts by weight are：60 ~ 100 parts of glass powder, α-
1 ~ 5 part of 5 ~ 6 parts of cyanoacrylate, 20 ~ 40 parts of polytetrafluoroethylene (PTFE) and tributyl 2-acetylcitrate.Coating spraying method is will be by
The compounding substances mixed are formulated as coating material, spraying conditions are：Oxygen flow 350 ~ 400 L/min, C3H8Flow 28 ~
34L/min, 0.35 ~ 0.42MPa of spray pressure, 90 ~ 110mm of spray distance.After spraying, coating layer thickness is 18 ~ 24 μm, wherein 6
~ 10 μm are small bulge-structure, and the surface of small bulge-structure is micro nano structure.Above-mentioned coating has persistent low temperature, resisted
The advantages of ageing properties are high and ice-covering-proof.According to bionic principle, the surface with small bulge-structure can have hates well
It is aqueous（Such as the surface of lotus leaf）, make surface that there is waterproof and self-cleaning function, from the current study, micro nano structure tool
Have the advantages that most of materials are incomparable, the inner surface of refrigerating chamber is designed as to the painting of the small bulge-structure with certain size
Layer, the characteristics of due in its structure so that the surface area of coating is very big, when water droplet is sprawled on the surface, in order to reduce
Surface tension, water droplet will shrink as spherical automatically, in addition, small bulge-structure can also cause water droplet can not in surface aggregation and
Stop so that water is not adsorbed on the surface, while a-cyanoacrylate and tributyl 2-acetylcitrate to a certain extent can
Ice is enough effectively reduced in freezing chamber surface covering phenomenon, is used in conjunction with above-mentioned small salient point structure, without obvious ice
Attachment phenomenon.
Compared with prior art, the advantage of the invention is that：In apparatus of the present invention cold air can comprehensive contact be frozen
Thing, temperature drop quickly, breaks through zone of maximum ice crystal formation in the short time, the core for being frozen thing reaches in a short time
The temperature of setting；The time that concentration solute and food tissue, colloid and various composition contact with each other inside cell tissue is short, dense
The injury of contracting drops to very low, analyses few outside ICW, juice loss is few during defrosting, and the mouthfeel of aquatic products is close to fresh after defrosting
Product, it is Fresh ＆ Tender in Texture flexible；Freezing chamber internal surface has the coating with micro nano structure, can effectively reduce freezing chamber surface
Icing phenomenon, reduces the waste of the energy.
