Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention mainly relates to large frozen blocks of beverages such as juices, coffee, and soups, and foods containing solutes such as butter and margarine, which are stored in a frozen state in drums. The present invention relates to a thawing tank device for granular frozen material that can be used to thaw, dissolve, and liquefy granular frozen material that has been made into small particles by crushing it with a crusher or the like.

(Prior art) Conventionally, this type of liquefaction of frozen granules has been carried out by recycling means to return the liquefied solution in a tank to the frozen granules in the same tank to facilitate melting, and by rotating a stirring blade within the tank. (see European Patent Application Publication No. 207899), and a type in which a heating pipe is installed outside the tank (Japanese Patent Laid-Open Publication No. 207899).
61-58544) is known.

(Problems to be solved by the invention) Depressing, youth, coffee, soup, butter,
Foods containing solutes such as margarine are susceptible to deterioration of the solutes and solvents by high-temperature heating processing or long-term heating processing. Therefore, it is desirable to devise ways to avoid high-temperature heating and long-term heating as much as possible.

The former technique described in the above conventional technology requires a relatively long thawing time because it does not have a means to heat the tank from the outside, and the stirring blade that rotates inside the tank is not configured to stir the entire inside of the tank. I don't like it.

Similarly, in the latter case, the pot body is easily affected by outside air in the area between the heating pipes.
This results in alternating locations of high temperature and low temperature locations on the wall surface of the pot body, which is undesirable because the solute burns on the same wall surface in the form of spiral stripes.

An object of the present invention is to provide a new thawing tank device for granular frozen bodies that is designed to shorten the thawing time and prevent solute from sticking.
