Quick-freezing device

Abstract

A quick-freezing device comprises a main barrel unit, a first isolation unit connected to the upstream side and a second isolation unit connected to the downstream side. The main barrel unit comprisesa body defining a freezing chamber, an upstream gate which is arranged on an upstream opening in a manner of being opened and closed, a downstream gate which is arranged on a downstream openingin a manner of being opened and closed and a conveying module arranged in the freezing chamber. The first isolation unit comprises a first barrel body defining a first isolation chamber and an inlet gate which is arranged at an inletin a manner of being opened and closed. The second isolation unit comprises a second barrel body defining a second isolation chamber and an outlet gate arranged at an outletin a manner of being opened and closed. When the conveying module conveys objects to be frozen, through cooperation of opening and closing of the inlet gate, the first gate, the second gate and the outlet gate, a freezing medium is prevented from escaping.

Description

technical field [0001] The invention relates to a freezing device, in particular to a quick-freezing device. Background technique [0002] refer to figure 1 , is an existing freezing equipment 1, comprising a conveyer belt 11 capable of transporting objects to be frozen 10 along a conveying direction, and a conveyer belt 11 arranged on the conveyer belt 11, and surrounding a freezing chamber 120 for accommodating refrigerated medium 12 of the casing. The casing 12 has an inlet 121 communicating with the freezing chamber 120 , and the object 10 to be frozen will enter the freezing chamber 120 through the inlet 121 when being transported on the conveyor belt 11 . The freezing chamber 120 is filled with a freezing medium used to reduce the temperature of the object 10 to be frozen. In the freezing chamber 120, the object 10 to be frozen will exchange heat with the freezing medium to cool down. [0003] Because whether the freezing medium can be retained in the freezing chamb...

AI Technical Summary

Problems solved by technology

[0003] Because whether the freezing medium can be retained in the freezing chamber 120 is related to the freezing performance of the freezing equipment 1, and if the freezing medium escapes from the freezing chamber 120 to the normal temperature and pressure of the outside, it cannot Reuse for freezing

However, in the process of the conveyor belt 11 continuously transporting the object 10 to be frozen, the freezing medium will inevitably escape through the inlet 121, thus causing the loss of the freezing medium, which not only affects the freezing performance and is difficult to maintain, but also frequently replenishes the freezing medium. Increased costs and material costs
