Abstract
The utility model discloses a liquid nitrogen immersion freezer, which comprises a liquid nitrogen storage tank and a liquid nitrogen trough, an outlet tube on the liquid nitrogen storage tank is extended into the liquid nitrogen trough, a nozzle is arranged on the end of the tube, and a spillover drain tube is also connected on the tube. The structure of the liquid nitrogen immersion freezer is reasonable, the liquid nitrogen immersion freezer can quickly freeze crisp coating outside crisp icecream, and has a good freezing effect, and the liquid nitrogen immersion freezer can be widely applied to the freezing of the crisp icecream.
Description
Technical field
The utility model relates to and a kind of food is carried out quick freezing device, particularly a kind of liquid nitrogen dipping freezing plant.
Background technology
At present, in the icecream production industry, in crackling manufacture of ice cream process, at first get ice cream through freezing machine, by the loading hopper on the filling machine ice cream regularly is poured on the stainless steel mould and is shaped, again mould is placed the freezing and inserted link of low temperature brine ice, then with the ice cream demoulding, be sent to chocolate by conveyer belt, finish the coating operation in the pulp groove, cold wind freezing method through routine after taking out freezes it, this method makes the crackling coating surface produce phenomenons such as fusion and surface checking easily, influenced the attractive in appearance of crackling ice cream surface, and crackling can not come off the embracing tightly of the ice cream in it easily, at above-mentioned shortcoming, be necessary to make improvements.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, can be fast to the outer liquid nitrogen that the crackling coating is freezed and freezing efficiency the is good dipping freezing plant of crackling ice cream.
The technical scheme that its technical problem that solves the utility model adopts is:
Liquid nitrogen dipping freezing plant comprises liquid nitrogen tank, liquid nitrogen tank, and introduction pipe stretches in the liquid nitrogen tank on the described liquid nitrogen tank, is positioned at pipe end and is provided with shower nozzle, also is connected with the overflow evacuated tube on pipeline.
In the utility model, described pipeline comprises the liquid nitrogen carrier pipe and is sleeved on its outer insulating tube.
The beneficial effects of the utility model are: during use, valve on the opening conduits, liquid nitrogen in the liquid nitrogen tank is drawn, and the shower nozzle of process pipe end is injected to liquid nitrogen in the liquid nitrogen tank, to scribble outer field ice creams such as chocolate, pulp clamps and puts into to liquid nitrogen tank by manipulator, make coating quick freezing in liquid nitrogen tank, because this moment, the temperature of coating can be significantly less than the ice-cream temperature of internal layer in moment, because of expanding with heat and contract with cold, chocolate, pulp crackling layer will tightly wrap the ice cream of the inside, effectively avoids coming off of coating; In addition, because the temperature of liquid nitrogen freezing is extremely low, thereby the hardness of crackling is higher, and appearance is very smooth and smooth, is not easy to produce phenomenons such as fusion and surface checking, has guaranteed good looking appearance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model structural representation in use.
The specific embodiment
With reference to Fig. 1, Fig. 2, liquid nitrogen dipping freezing plant comprises liquid nitrogen tank 1, liquid nitrogen tank 2, and introduction pipe 3 stretches in the liquid nitrogen tank 2 on the described liquid nitrogen tank 1, is positioned at pipeline 3 ends and is provided with shower nozzle 4, also is connected with overflow evacuated tube 5 on pipeline 3.
Wherein, described pipeline 3 comprises liquid nitrogen carrier pipe 31 and is sleeved on its outer insulating tube 32.During use, valve on the opening conduits 3, liquid nitrogen in the liquid nitrogen tank 1 is drawn, and liquid nitrogen is injected in the liquid nitrogen tank 2 through the shower nozzle 4 of piping 3 ends, to scribble outer field ice creams 7 such as chocolate, pulp clamps and puts into to liquid nitrogen tank 2 by manipulator 6, make coating quick freezing in liquid nitrogen tank 2, because this moment, the temperature of coating can be significantly less than the ice-cream temperature of internal layer in moment, because of expanding with heat and contract with cold, chocolate, pulp crackling layer will tightly wrap the ice cream of the inside, effectively avoids coming off of coating; In addition, because the temperature of liquid nitrogen freezing is extremely low, thereby the hardness of crackling is higher, and appearance is very smooth and smooth, is not easy to produce phenomenons such as fusion and surface checking, has guaranteed good looking appearance.
The utility model is rational in infrastructure, can freeze the outer crackling coating of crackling ice cream fast and freezing efficiency good, be a kind of liquid nitrogen dipping freezing plant that is widely used in the crackling ice cream is carried out freezing processing.
