Dry ice freezing treating and conveying line

Abstract

The invention discloses a dry ice freezing treating and conveying line. The dry ice freezing treating and conveying line comprises a spiral rotating body and a rotating driving body and further comprises a material feeding port and a dry ice feeding port, wherein the rotating driving body is used for driving the spiral rotating body to rotate; one end of the spiral rotating body is determined as a spiral rotating start end according to the rotating direction of the spiral rotating body, and the other end of the spiral rotating body is a spiral rotating tail end; the material feeding port and the dry ice feeding port can supply a plurality of materials and a plurality of dry ice to enter the spiral rotating body through the spiral rotation start end and to be mixed; and a dry ice screening device is further arranged on the spiral rotating body and can screen the dry ice so as to enable the dry ice to be always located on the spiral rotating body and be unable to be synchronously conveyed to the spiral rotating tail end in the rotating process of the spiral rotating body. According to the dry ice freezing treatment conveying line, dry ice freezing treating and conveying of the materials can be completed integrally in the rotating process of the spiral rotating body, in addition, the dry ice and the materials can be fully attached so that dry ice freezing treatment can be rapid and thorough without dead angles, the structure is reasonable, and convenience and high efficiency can be realized.

Description

【Technical field】 [0001] The invention relates to a processing line, in particular to a dry ice freezing processing conveying line. 【Background technique】 [0002] In some fields, freezing treatment is required. For example, in the field of aquatic products, it is necessary to transport aquatic products long-distance after freezing treatment, so as to achieve the effect of preserving quality and freshness. At present, the commonly used method is to place the items that need to be frozen in ice cubes or in a cold storage. Although this can reduce the items to a lower temperature, it is affected by the temperature of the ice cubes themselves. It is difficult to lower the temperature of the items to a lower temperature, and the cooling effect is not obvious. The cooling process takes too long. It is difficult to improve the freezing processing speed, and the texture, freshness and taste of the items are affected because the items cannot be cooled quickly. Secondly, the way of ...

At present, the commonly used method is to place the items that need to be frozen in ice cubes or in a cold storage. Although this can reduce the items to a lower temperature, it is affected by the temperature of the ice cubes themselves. It is difficult to lower the temperature of the items to a lower temperature, and the cooling effect is not obvious. The cooling process takes too long. It is difficult to improve the freezing processing speed, and the texture, freshness and taste of the items are affected because the items cannot be cooled quickly. ;Secondly, the way of cooling treatment with ice cubes makes the freezing treatment area often accumulate water, polluting the treatment process, and the way of cooling treatment in cold storage has disadvantages such as high cost and waste of energy

[0003] At present, dry ice freezing is used in many fields for freezing treatment, such as covering the surface of the material to be frozen with dry ice, or placing dry ice on the bottom layer or surroundings of the material to be frozen, but in the process of application, we found that the above The simple dry ice freezing method cannot achieve the ideal and expected effect. The material that is attached to the dry ice has been frozen by dry ice, but the part that is not attached to the dry ice cannot achieve a good cooling effect.
