Abstract
The utility model discloses a tunnel quick-freezing device capable of recovering nitrogen. The tunnel quick-freezing device capable of recovering the nitrogen comprises a tunnel cold chamber, a conveying belt, a liquid nitrogen storage tank and a nitrogen recovering container. The conveying belt passes through the interior of the cold chamber, the liquid nitrogen storage tank is communicated to the upper portion of the cold chamber, the nitrogen recovering container is communicated to the cold chamber, and a first fan is arranged on a communication path of the nitrogen recovering container and the cold chamber. The nitrogen recovering container is arranged on the outer side of the cold chamber, recovered nitrogen can be generated to be liquid nitrogen through a nitrogen generating machine, reuse is achieved, consumption of the liquid nitrogen is reduced, and production cost is controlled.
Description
Technical field
The utility model relates to a kind of tunnel type quick refrigerating unit, relates in particular to a kind of tunnel type quick refrigerating unit of the nitrogen that can be recycled.
Background technology
With liquid nitrogen as the quick-freezing plant of cold-producing medium mainly by three kinds of impregnated, fountain and cold air circulatings, these several modes almost are suitable for freezing the little food of all volumes.Simultaneously, the liquid nitrogen flash freezer mode also has following characteristics: nontoxic, can prevent the oxidation of food, and the fragrant effect of protecting is arranged; Freezing speed is fast, and rate of temperature fall can arrive .50 ℃/minute, and the quick-frozen time is 3.18 minutes; Food contacts fully with liquid nitrogen, and heat transmission resistance is little; The drying loss of frozen food is little.But the cost of liquid nitrogen is high, should not freeze cheap food.And the quick-freezing plant of prior art lacks the retracting device to nitrogen, and ordinary circumstance is, after liquid nitrogen vaporization is nitrogen, directly with nitrogen discharge in atmosphere.This mode more is unfavorable for the production control cost, has caused waste.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of tunnel type quick refrigerating unit of recyclable nitrogen, and the nitrogen after the recovery can be made liquid nitrogen again, reuses, and has reduced the consumption of liquid nitrogen, has controlled production cost.
The technical scheme that the utility model provides is:
A kind of tunnel type quick refrigerating unit of recyclable nitrogen comprises:
The tunnel type cold house;
Conveyer belt, its inside by described cold house is passed through;
Liquid nitrogen storage tank, it is communicated to the top of described cold house; And
The nitrogen recycling container, it is communicated to described cold house, and the communication path in described nitrogen recycling container and described cold house is provided with one first fan.
Preferably, the tunnel type quick refrigerating unit of described recyclable nitrogen also comprises:
A plurality of the second fans are arranged on the top of described cold house;
The rear side that the position is positioned at a plurality of the first fans that is communicated with of described liquid nitrogen storage tank and described cold house;
The front side that the position is positioned at described a plurality of the second fans that is communicated with of described nitrogen recycling container and described cold house.
Preferably, the tunnel type quick refrigerating unit of described recyclable nitrogen also comprises:
Spray equipment, it is arranged on the inside of described cold house, is communicated with described liquid nitrogen storage tank.
Preferably, the tunnel type quick refrigerating unit of described recyclable nitrogen also comprises:

The utility model in the arranged outside of cold house the nitrogen recycling container, the nitrogen after the recovery can be made liquid nitrogen by nitrogen making machine again, reuses, and has reduced the consumption of liquid nitrogen, has controlled production cost.
Description of drawings
Fig. 1 is the structural representation of the tunnel type quick refrigerating unit of recyclable nitrogen described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As scheme shown in the l, the utility model provides a kind of tunnel type quick refrigerating unit of recyclable nitrogen, comprising: tunnel type cold house 5; Conveyer belt 4, its inside by described cold house is passed through; Liquid nitrogen storage tank 3, it is communicated to the top of described cold house; And nitrogen recycling container 6, it is communicated to described cold house, and the communication path in described nitrogen recycling container and described cold house is provided with one first fan 7.
The inwall of one tunnel type casing is coated with heat-insulating material, has just formed the tunnel type cold house at box house.The both sides of cold house have entrance and exit, and conveyer belt is passed through by the inside of cold house, and food to be processed is fed through inside, cold house.
" front side " described in the utility model and " rear side " are for for the direct of travel of food, and the food first zone of process is the front side, after the food through the zone be rear side.
Liquid nitrogen is sprayed into inner to the cold house by spray equipment, with Food Contact, heat exchange occurs; Become nitrogen behind the liquid nitrogen vaporization, a plurality of the second fans 2 are set in the front side of spray nozzle device, help forward side flow of nitrogen, again the food that newly enters is carried out precooling, can take full advantage of cold like this.
Nitrogen recycling container 6 is communicated to the cold house by a nitrogen recycling passage 1, this nitrogen recycling passage is positioned at the front end of cold house, and the first fan 7 is set in the nitrogen recycling passage, with to nitrogen gas generation suction, nitrogen is flowed out from this nitrogen recycling passage, and can not leak from the entrance and exit position of cold house.
The tunnel type quick refrigerating unit of described recyclable nitrogen also comprises: a plurality of the second fans are arranged on the top of described cold house; The rear side that the position is positioned at a plurality of the first fans that is communicated with of described liquid nitrogen storage tank and described cold house; The front side that the position is positioned at described a plurality of the second fans that is communicated with of described nitrogen recycling container and described cold house.
The tunnel type quick refrigerating unit of described recyclable nitrogen also comprises: spray equipment, it is arranged on the inside of described cold house, is communicated with described liquid nitrogen storage tank.
The tunnel type quick refrigerating unit of described recyclable nitrogen also comprises: nitrogen making machine, it is communicated with described nitrogen recycling container.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
