Specific embodiment
Existing object (herein by taking meat as an example) thawing mode mainly include the following types:
(1) refrigeration is thawed.Frozen meat is placed in refrigerating chamber and is slowly thawed, very little is lost to the delicate flavour of frozen meat in this way, still
It needs to take a long time, about at one day or more.
(2) air thawing method.Frozen meat is packaged or be put into crisper with preservative film and is placed in desktop, delicate flavour loss is little, but
It is analogous to refrigeration to thaw, still can take a long time.
(3) hot water thaws.Frozen meat is impregnated in the hot water, so that the surface of frozen meat is brought rapidly up and thaws, but is thawed
Usually still there is ice cube in the centre of meat afterwards, so that defrosting uniformity is poor.In addition, the microbial growth journey during hot water defrosting
It is very fearful to spend, and water can become cloudy in course of defrosting, and a large number of nutrients is dissolved in water, so that the delicious degree of meat,
Mouthfeel can all be deteriorated.
(4) cold water thaws.Frozen meat is immersed in cold water, it is slightly better compared with hot water thaws, but in soaking process
In, cold water can also dissolve nitrogen substance and vitamin in meat, lead to microbial reproduction, and it is only slightly slower than hot water, and thaw
Time also can be very long.
(5) defreezing by microwave oven.Frozen meat is placed in micro-wave oven and is thawed, frozen meat thaws from outside to inside, and defreezing by microwave oven is bad
Estimated weight and thawing time often bake part meat.
(6) radio frequency thaws: the existing radio frequency defrosting scheme based on bipolar plates capacitor and plate aerial, although certain
Frozen meat defreezing can be completed in degree, but uses parallel-plate structure, be not easy to the realization of the thawing apparatus of miniaturization, and need
Adaptation matches come the energy transmission for realizing power source to parallel capacitance plate, at high cost, and the high voltage between parallel capacitance plate,
It is unfavorable for the application of commercialization.
There is different limitations in above-mentioned several defrosting schemes, as thawing time is long, defrosting uniformity is poor, uncomfortable
The defrosting of mass is answered to operate etc., in this regard, the present invention provides a kind of unipolar plate thawing apparatus 10 and thawing equipment 20, on solving
Problem is stated, thawing time, the uniformity for ensuring to thaw and unfreezing quality are substantially shortened.Below in conjunction in the embodiment of the present invention
