Technical field
The present invention relates to a kind of low drying loss quick-freezing plants, and the method for freezing based on the device.
Background technology
With the quickening of social life rhythm, quick-frozen food becomes one of food industry with fastest developing speed in the world today.
In recent years, volume of trade is every year with 10% ~ 30% speed increase.Data shows that year consumption freezes per capita for developed country at present
Food is generally at 20 kilograms or more, and with 30% speed increase.Quick-frozen food has become food with fastest developing speed in the world today
One of product.Quick-frozen food total output in the world's is more than 60,000,000 tons at present, 3500 kinds or so of kind, China's food industry also therewith into
Polynary, high speed a developing stage is entered, reduce production cost and new product is developed into each frozen food factory
The Critical policies that family dominates the market.
In fact, each food can all generate different degrees of drying loss in freezing process.The presence of drying loss, not only lowers
Yield rate in food product refrigeration process, and seriously affected the color and luster and quality of food, there are substandard products.
In general, freeze that wind speed is higher, and food drying loss is more serious, meanwhile, drying loss also has relationship, freeze-off time with freeze-off time
Longer, drying loss is more serious.However, freeze also have direct relationship between wind speed and freeze-off time, it is higher to freeze wind speed, when freezing
Between it is shorter.Which results in existing quick-freezing plants to be difficult to make progress in terms of reducing drying loss：If freezing speed is low, freeze
The knot time is long, can not avoid drying loss, and low output；If freezing speed is fast, the big problem of food drying loss is equally existed, and waste
Resource.

Air supply velocity is 20-30m/s.
As a further improvement on the present invention：The rack upper edge freezing channel is equipped with more than two for installing partition board
Installation site；
Alternatively, the partition board is connect with housing slide, the glide direction is consistent with freezing channel trend, is additionally provided with for by partition board
The fixing device being fixed on the rack.
Method of freezing based on above-mentioned low drying loss quick-freezing plant：The installation site of partition board is adjusted first；Then pass through biography
Send device that article to be frozen is made to pass through the first freezing section and the second freezing section successively：When by the first freezing section, cold wind will wait for cold
Freeze article surface to freeze, locks the moisture inside article；When by the second freezing section, cold wind is by article fully charge to be frozen.
Compared with the existing technology, the present invention has the positive effect that：（1）It is cold that refrigerating process is divided into low wind speed by the present invention
Freeze and high wind speed freezes two stages, the freezing of article surface is realized in the low wind speed stage, thus by moisture lock inside article,
Into high wind speed freezing stage again by entire article all freeze, not only reduce it is quick-frozen during drying loss, improve food
Quality, and quick-frozen efficiency is improved, save resource；（2）It is cooled down by the way of blowing simultaneously up and down, is further contracted
Short cooling time, and the proportioning of air output up and down can be adjusted according to article situation；（3）Using interior circulative metabolism, reduce
The burden of aerial cooler；（4）Can be according to article to be frozen the case where, realizes that the first stage is cold by adjusting partition position
Freeze the adjustment of time, using flexible is applied widely.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the schematic cross-section of the present invention.
Specific implementation mode
The technical solution that the invention will now be described in detail with reference to the accompanying drawings：
Such as Fig. 1 and 2, a kind of low drying loss quick-freezing plant, including rack.Attemperator 4 is installed to surround freezing in the rack
Channel, attemperator 4 refer to a kind of building enclosure for separating environment between freezing zone environment and food processing, generally use poly- ammonia
Ester foaming battenboard can effectively block the cold of freezing zone to be lost in.
Device further includes the transmission device 1 for transmitting article to be frozen along the freezing channel, and the transmission device 1 is excellent
It is selected as transmission belt, can also be other machinery device, be such as transmitted using transmission chain, article to be frozen is lifted on transmission chain
It is upper, etc..
The rack upper top is equipped with several aerial coolers 2 along direction of transfer arrangement, and each aerial cooler 2 connects respectively
