Embodiment Construction

[0021] The invention is a quick-freezing device, which is mainly used for quick-freezing of fish goods on fishing boats.

[0022] When the fishery goods are manually loaded into the fish pan (9), the fish pan (9) is placed in the evaporating plate (1), and the cooling of the evaporating plate (1) and the blowing of the axial flow fan (8) are combined to realize the fishy goods. quick freezing.

[0023] During the refrigerant evaporation process of the refrigeration system, the refrigerant enters the finned tube (3) to evaporate through the liquid supply connection pipe (2), and when the refrigerant passes through the mixed flow tube (4), the refrigerants with different evaporation states are mixed together Evaporate again, and then evaporate again through the mixed flow tube (4). After the evaporation process is repeated several times, the refrigerant returns to vapor from the vapor return connection pipe (5), thereby realizing a cycle.

[0024] The mixed-flow pipe (4) connec...

Abstract

The invention discloses a set of quick-freezing equipment which is mainly applied to quickly freezing fish goods on fishing boats and particularly relates to a mixed-flow shelf freezer for boats. According to the mixed-flow shelf freezer for boats, because a mixed-flow tube is connected with a finned tube of an evaporation plate, refrigerant can flow in a mixed mode in the evaporation process of the finned tube of the evaporation plate, refrigerant which is nonuniform or incomplete in evaporation can be evaporated again after the mixed flow, and thus the effect of uniform and complete evaporation is achieved. According to the purpose of the mixed-flow shelf freezer for boats, the connection mode of a finned tube of an evaporation plate in an existing shelf freezer is replaced, so that the refrigerant can be evaporated in the finned tube more completely and uniformly, and the evaporation process is not affected by the length of the evaporation loop. The mixed-flow shelf freezer for boats is applicable to both a fishing boat refrigeration system and a refrigeration system on land.

Description

Technical field [0001] The invention relates to a device, in particular to a marine mixed-flow shelf freezer. Background technique [0002] The fish caught by offshore or ocean-going fishing vessels need to be kept fresh. Fishing products that are kept fresh by cold storage are usually quick-frozen through the shelf freezer in the quick-freezing cabin, and then stored in the cold storage cabin when the central temperature of the fish body reaches the required level. [0003] Shelf freezers are used for quick freezing of fishery goods. After the fish is caught on the deck, the fish is manually loaded into the fish tray and placed on the shelf of the shelf freezer to freeze. [0004] At present, the shelf freezers used in the market all use aluminum alloy evaporation plates as shelves. There are 2 finned tubes under each evaporating plate, and multiple evaporating plates form a set of shelves, and the finned tubes of each set of shelves are connected to form a set of evapor...
