Embodiment 1

[0031] Such as figure 1 and figure 2 As shown, a high-efficiency low-temperature quick-freezing machine includes an externally placed thermal insulation storage body 1, and the thermal insulation storage body 1 is assembled with polyurethane sandwich double-sided stainless steel plates. The main part of the heat exchange system 3 is installed in the heat preservation storehouse body 1, and the heat exchange system 3 includes an air supply device 31 for providing strong cold air in a vertical downward direction and a refrigeration device 32 for absorbing hot air in the heat preservation storehouse body 1. The device 32 is mainly arranged directly below the air supply device 31, and a quick-freezing chamber is formed in the thermal insulation storehouse body 1 between the two; Based on the conveying mesh belt 21 for conveying frozen products and the power source for driving the conveying mesh belt 21, the thermal insulation storage body 1 has a feed inlet and a discharge port ...

Embodiment 2

[0042] A quick-freezing process for shrimp products, using the quick-freezing machine described in Example 1, the whole process is carried out in a thawing chamber, and the temperature of the thawing chamber is controlled at 20°C, specifically comprising the following steps:

[0043] S1, defrosting raw shrimp;

[0044] Thaw the purchased frozen raw shrimp, specifically soak the raw shrimp in a thawing tank with a cold water temperature of 15°C, and thaw for at least 8 hours to reduce the contact between the shrimp body and oxygen in the air, control the temperature, and weaken the molecular heat Exercise, thereby reducing the efficiency of oxidation, choose the evening time, and reasonably allocate the time in the processing cycle. After thawing, the quality and sanitation inspection of the shrimp body is carried out, and the unqualified shrimp body is discarded.

[0045] S2, cleaning and sorting;

[0046] Arrange manpower to lay the shrimp body on the conveyor belt connecte...

Abstract

The invention discloses an efficient low-temperature instant freezer, and a shrimp product instant freezing processing technology applying the same, and relates to the technical field of instant freezing technologies. The problems that in the prior art, the instant freezing processing time is long, thus electric energy consumption is more, frozen products are bonded with one another, the loss is generated and thus the production cost is enlarged are solved. The efficient low-temperature instant freezer is characterized in that the efficient low-temperature instant freezer comprises a conveyingdevice for conveying the frozen products, and the conveying device comprises a conveying net belt penetrating through an instant freezing chamber; the instant freezer further comprises a heat exchanging system, and the heat exchanging system comprises an air supplying device for blowing cold air to the frozen products, and a refrigerating device for absorbing heat; the instant freezing chamber for allowing the conveying net belt to penetrate is formed between the air supplying device and the refrigerating device; and the refrigerating device comprises a containing box with an opening, and a solution which is placed in the containing box and is in a supersaturated state, the solubility of a solute in the solution is increased along with rising of the temperature, and the purpose of reducing of the freezing processing duration for the frozen products is achieved.

Description

technical field [0001] The invention relates to the technical field of quick-freezing technology, in particular to a high-efficiency low-temperature quick-freezing machine and a quick-freezing processing technology for shrimp products using the same. Background technique [0002] At present, the equipment commonly used for quick freezing of food is quick-freezing machine, which is a kind of high-efficiency freezing equipment that can freeze a large amount of frozen products in a short time. It can effectively and economically freeze a variety of frozen products placed inside the quick freezer, such as various shapes of meat, fish, shrimp, meatballs, vegetables, prepared foods, dairy products, etc. Quick-freezers can generally be divided into push-type quick-freezers, reciprocating quick-freezers, plate quick-freezers, fluidized quick-freezers, tunnel quick-freezers, spiral quick-freezers, lifting quick-freezers, etc. [0003] For the processing of Penaeus prawns, polyphenol...
