Specific embodiment
It is right as follows in conjunction with drawings and embodiments to keep the purpose, technical solution and effect of the application clearer, clear
The application is further described.
The application provides a kind of defrosting plate, can be used for the chilled food that thaws, and can be applied to family, dining room, food processing factory
Deng, can defrosting chilled food rapidly and efficiently, and can guarantee the quality of food.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the structural schematic diagram of the application defrosting plate first embodiment, and Fig. 2 is solved in Fig. 1
Freeze plate along the diagrammatic cross-section in the direction AA.In this embodiment, defrosting plate 101 is metal plate, and cavity is formed with inside it
102, gas/liquid is sealed in cavity 102, wherein the phase transition temperature of the gas/liquid is minus 20 degrees to 10 degree above freezing.
Specifically, when the food of freezing is placed on defrosting plate 101, the gas/liquid in defrosting plate 101 is undergone phase transition
(gas pre-cooling, which becomes liquid or liquid pre-cooling, becomes solid) release heat makes it for the food on heating defrosting plate 101
It thaws；Defrosting plate 101 selects the preferable metal plate of thermal conductivity, can accelerate hot transmitting, improves defrosting efficiency.Pass through this side
Formula can either accelerate thawing rate, shorten thawing time, and heating temperature is not high, does not influence the quality of food；Structure is simple,
Can repetitive cycling use, it is safer, healthy, environmentally friendly.
In one embodiment, it is filled with gas refrigerant, such as freon, 1 in the cavity 102 of defrosting plate 101,1,1,
One of 2- tetrafluoroethane (R134a), iso-butane (R600a), pentafluoroethane (R125) etc..These gases are in certain pressure
Under, it is gas under room temperature, can be undergone phase transition within the scope of -20~10 DEG C, become liquid；Heat is discharged in phase transition process,
Play the role of heating to thaw.The pressure of gas is 0~20MPa in cavity 102, it is therefore preferable to 0~2MPa, such as 0.5MPa,
1.0MPa, 1.5MPa, 2.0MPa, 5MPa, 10MPa, 20MPa etc..Before phase change, the pressure of gas is bigger, then gas content is got over
More, the heat that pre-cooling discharges when undergoing phase transition is more, and the thawing speed of food is faster；But pressure is bigger, to defrosting plate 101
Material require it is higher.It therefore, can be according to the material of defrosting plate 101, application environment, filling gas type etc., adaptability choosing
Select the pressure value of relatively optimization.Selection in the cavity 102 of defrosting plate 101 filling gas, can mitigate defrosting plate 101 weight,
It is easy to carry.
In another embodiment, it is filled with liquid refrigerant in the cavity 102 of defrosting plate 101, such as: polyvinyl alcohol, boron
The mixture of sand and water, one of sodium-chloride water solution.Liquid refrigerant is fillable in cavity 102, can also contain
Loaded on being laid in after container bag in cavity 102.The phase transition temperature of the liquid is equally within the scope of -20~10 DEG C.Liquid is selected to store
Cryogen can enhance the thermal capacity of defrosting plate 101, improve thawing rate, and make it to be suitable for the temperature difference compared with subenvironment defrosting.And
Opposing gas refrigerant, simply, conveniently, the risk of leakage is smaller for packaging method.
In one embodiment, defrosting plate 101 selects the higher metal plate of thermal coefficient, such as: aluminium alloy plate, copper alloy
One of plate, silver alloy plate, albronze plate.Aluminium alloy plate is selected, not only thermally conductive fast, quality is also light；And select copper alloy
Plate, silver alloy plate, in addition to the thermally conductive fast, light weight the advantages that other than, additionally it is possible to play the role of sterilization, guarantee food quality.
Please continue to refer to Fig. 1 and Fig. 3, Fig. 3 be in Fig. 1 defrosting plate along the diagrammatic cross-section in the direction BB.Preferably
In, the inside of defrosting plate 101 has partition 103, and cavity 102 can be divided into multiple small cavitys.In this way can
It prevents gas/liquid from gathering, promotes thermal cycle.Defrosting plate 101 can also be divided into multiple spaces, filling is different in different spaces
Gas/liquid；So that defrosting plate 101 has multiple " functional areas ", the food under selective defrosting different temperatures.In other realities
It applies in mode, can also directly be laid with multiple pipelines, gas/liquid is directly filled in pipeline.
Referring to Fig. 4, Fig. 4 is the structural schematic diagram of the application defrosting plate second embodiment.In this embodiment, it solves
The surface for freezing plate 401 has multiple grooves and/or protrusion 402.By setting groove and/or protrusion 402, can effectively increase
The surface area of defrosting plate 401, to effectively increase its endotherm area；Groove 402, which can also store to thaw, is formed by water, makes
Defrosting plate uses more convenient.
Referring to Fig. 5, Fig. 5 is the structural schematic diagram of the application defrosting plate third embodiment.In this embodiment, it selects
The cavity of defrosting plate 501 is sealed with sealing element 502, sealing element 502 can be metal, rubber etc..Sealing element 502 can only be set
It sets in one end of defrosting plate 501, can also be all arranged with both ends.Select split type sealing element 502, the gas being convenient for changing in cavity
Defrosting plate is recycled for multiple times in body/liquid.In other embodiments, defrosting plate is integrated calendering formation, aerobic loading
After body/liquid, direct calendering formation sealing, in this way, sealing effect is good for choosing, should not reveal, but because being integrally formed,
The gas/liquid in cavity cannot be flexibly replaced after obtaining product.
In one embodiment, defrosting plate be square, one of rectangle, circle, ellipse, naturally it is also possible to be
Other arbitrary shapes may be provided for component hung etc..
The application provides a kind of defrosting plate, and phase transition temperature is sealed in the defrosting plate as minus 20 degrees to 10 degree of gas above freezing
Body/liquid, when the food of freezing is placed on the defrosting plate, the gas/liquid in defrosting plate undergoes phase transition (gas pre-cooling change
Become solid for liquid or liquid pre-cooling) heat is discharged, for the food on heating defrosting plate, make its defrosting；Defrosting plate choosing
With the preferable metal plate of thermal conductivity, hot transmitting can be accelerated, improve defrosting efficiency.In this way, can either accelerate to thaw
Speed shortens thawing time, and heating temperature is not high, does not influence the quality of food；Structure is simple, can repetitive cycling use,
It is safer, healthy, environmentally friendly.
The foregoing is merely presently filed embodiments, are not intended to limit the scope of the patents of the application, all to utilize this
Equivalent structure or equivalent flow shift made by application specification and accompanying drawing content, it is relevant to be applied directly or indirectly in other
Technical field similarly includes in the scope of patent protection of the application.
