Description

Technical Field

[0001] The utility model relates to the technical field of food quick-freezing equipment, in particular to an accelerating cooling device for flavored shrimps. Background Art

[0002] As a kind of food, shrimps are rich in nutrition, delicious in taste, soft in meat and easy to digest, and have a wide consumer group. We can eat shrimps in restaurants or cook them at home by ourselves. However, the processing and cooking process is cumbersome, which discourages a large number of enthusiasts. In order to enable more people to eat delicious shrimps, we clean and cook the shrimps to make flavored shrimps, and then quick-freeze them into prefabricated foods, which are not only convenient for storage and transportation, but also convenient for consumption, bringing good news to food lovers.

[0003] To ensure the food hygiene of flavored shrimps, it is necessary to quickly complete the cooling and temperature reduction through quick-freezing to prevent bacteria from breeding during the intermediate process due to slow temperature reduction. Moreover, quick-freezing and cooling can also avoid nutrient loss and ensure the delicious taste of shrimps. When cooling and quick-freezing flavored shrimps through a liquid nitrogen cooler, the specific operation is to place the flavored shrimps on a plate and transport them into the liquid nitrogen cooler through the cooling conveyor line of the liquid nitrogen cooler. Liquid nitrogen is filled in the liquid nitrogen cooler for temperature reduction, and synchronous transportation and cooling and quick-freezing are carried out. The cold energy inside the liquid nitrogen cooler is easily lost from the front conveying inlet. Although there is a curtain at the inlet, the curtain is relatively short and energy loss cannot be avoided. Instead of letting the cold energy be lost without reason, it is better to make full use of it to pre-cool the flavored shrimps and accelerate the overall cooling process. Therefore, an accelerating cooling device for flavored shrimps is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides an accelerating cooling device for flavored shrimps, which is used to achieve the purpose of reducing cold energy loss of the liquid nitrogen cooler and accelerating the cooling of flavored shrimps.

[0006] An accelerating cooling device for flavored shrimps includes a plate placing conveyor installed at the front end of a liquid nitrogen cooler. The height of the conveyor belt surface of the plate placing conveyor is not less than the height of the conveyor belt surface of the cooling conveyor of the liquid nitrogen cooler. A pre-cooling cover is arranged on the cooling conveyor to cover the entire conveyor belt surface of the cooling conveyor. One end of the pre-cooling cover far away from the plate placing conveyor is movably hinged to the liquid nitrogen cooler;

[0007] Sealing strips I are installed on the lower edges of both sides of the pre-cooling cover. A sealing strip II is installed between the edge of one end of the pre-cooling cover far away from the plate placing conveyor and the liquid nitrogen cooler. A heat preservation layer is pasted on the inner wall of the pre-cooling cover.

[0008] Preferably, the width of the swing conveyor is matched with the width of the cooling conveyor, and the swing conveyor is fixed to the front end of the liquid nitrogen cooler by a buckle lock.

[0009] Preferably, flip handles are fixed on both sides of the pre-cooling cover.
