Industrial small ice rapid manufacturing system with continuous circulation method {SYSTEM FOR RAPIDLY MAKING CONTINUOUS-CIRCULATING SMALL-SIZED ICE FOR INDUSTRY}

The present invention relates to an industrial small-scale ice rapid manufacturing system, and in detail, when a plurality of ice molds for manufacturing small-scale ice are filled with water by a transfer tray chain and then rotated, they are immersed in an ethanol tank and frozen to prepare ice. An industrial type of continuous circulation system that allows small ice to be manufactured in a short time by applying hot air in a state where the ice mold is inverted with the transfer tray chain, and the ice is dropped from the mold, discharged along the discharge chute, and then re-filled with water for continuous circulation. It relates to a small ice rapid manufacturing system.

In general, ice is used for various purposes in a variety of industries such as aquatic products, poultry processing and freshness maintenance, food processing, and chemical factories. In particular, aquatic products and poultry can be processed and maintained freshly by supplying ice just before packaging when shipping products. And prevent corruption.

As described above, ice is widely used in various industrial fields. Industrial ice makers produce a large amount of ice, crush it with an industrial ice maker, and temporarily store it in an ice storage bin, which is an industrial large-capacity storage unit, and then supply secondary ice to each supplier that needs ice. Is done.

These industrial ice makers put sterilized water into a large rectangular ice cube at a constant capacity, and immerse the large ice cube in a cooling solution at 9 ° C to freeze the water in the ice cube.

Then, in the large ice cube, the water starts to freeze from the edge, and when it freezes to some extent, it is taken out, and after washing, ice is crushed with an ice machine and then packed.

However, such a large industrial ice maker and a commercial ice maker have to be installed, requiring expensive equipment, and having a large installation area, which increases the investment cost.

On the other hand, as an ice-making method, there are disclosed an air freezing method, a contact freezing method, a immersion freezing method, a liquefied gas freezing method, and a low temperature osmotic dehydration freezing method.

As an example of such an ice-making method, there is disclosed an ice machine for manufacturing ice cubes, which is Korean Utility Model Registration No. 20-0280249.

As shown in FIG. 1, the ice maker for manufacturing ice cubes is composed of an ice maker 11 at the top and an ice storage chamber 12 at the bottom, and the refrigeration unit 2 is a conventional refrigeration cycle. The components of the refrigeration cycle, such as a compressor, a condenser, and a receiver, are mounted on the refrigeration device 2, and among the components of the refrigeration cycle, heat is supplied from a low temperature low pressure atomized refrigerant from an expansion valve. The ice-making unit 3, which replaces the components of the evaporator that cools around by the action, is configured to be installed in the ice-making chamber 11 of the ice-maker body 1.

However, such a conventional ice maker for producing ice has a problem in that mass production is impossible due to a relatively slow ice production speed.
