Novel tunnel liquid ammonia instant freezer

Abstract

A novel tunnel liquid ammonia instant freezer is characterized by being composed of a liquid ammonia storage tank, a refrigerating compressor, a liquid ammonia delivery pipe, an instant freezer body,a freezing chamber, an evaporator, a first freezing conveying belt, a second freezing conveying belt, a conveying belt, an ice glaze chamber, an ice water tank, a solid ice chamber, an instant freezersupport and an instant freezer feeding port. The liquid ammonia storage tank is of a bilayer structure with an inner container and an outer container, liquid ammonia is stored in the inner container,diameter of the liquid ammonia delivery pipe is 10cm, and the refrigerating compressor delivers liquid ammonia to the freezing chamber of the instant freezer body and the evaporator of the solid icechamber through the liquid ammonia delivery pipe to refrigerate the freezing chamber and the solid ice chamber; the instant freezer body is composed of the freezing chamber, the ice glaze chamber andthe solid ice chamber, the first freezing conveying belt is positioned above the freezing chamber, the second freezing conveying belt is positioned in the middle of the freezing chamber, and the conveying belt is positioned below the freezing chamber; the ice glaze chamber is positioned at the rear end of the freezing chamber, the solid ice chamber is positioned at the rear end of the ice glaze chamber, the instant freezer body is made of square steel, and the instant freezer feeding port is positioned above the freezing chamber.

Description

technical field [0001] The invention relates to a quick-freezing machine, in particular to a novel tunnel liquid ammonia quick-freezing machine. Background technique [0002] As far as the applicant knows, the lobster tails are manually deheaded, rinsed, sterilized, then frozen, ice-coated, ice-fixed, etc., and then sent to a cold storage for sale after packaging. The freezing, icing, and ice-fixing of aquatic products such as shrimp tails are generally carried out in tunnel liquid ammonia quick-freezers. Due to the defect in the design of the current tunnel liquid ammonia quick-freezing machine (the conveyor belt in the freezing chamber is short), in order to ensure the freezing effect, the conveying speed must be reduced. When freezing aquatic products, it takes a long time to freeze, the conveying speed of the conveyor belt is slow, and the production efficiency is low. . There has been no good solution to the above problems. Contents of the invention [0003] Aiming...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the defects in the design of the current tunnel quick-freezing machine (short conveyor belt in the freezing chamber), long freezing time, slow conveying speed of the conveyor belt, and low production efficiency when freezing aquatic products such as shrimp tails, a new type of tunnel liquid ammonia is proposed.
