[Effect]

The present invention provides a cutting unit that uses an electric cutting tool such as a chainsaw, an electric circular saw, or an electric band saw, which receives a cylindrical frozen food block frozen in a large drum on a cutting table and divides it into a plurality of pieces; A table lifter that receives the ring-shaped divided body and transports it to the next process, a crusher that crushes the ring-shaped divided body received from the table lifter onto the input table into small particles, and a crusher that receives the frozen granules from the crusher and liquefies it by heating. A thawing machine is constructed in which a thawing tank device and a thawing tank device are installed in a continuous arrangement, and the thawing machine converts a frozen food block of the size of a large drum into sliced pieces, and the sliced pieces are turned into frozen granules. It is characterized by sequentially carrying out the process of liquefying the frozen granules, so it is possible to use frozen foods containing solutes such as juices, coffee, soups, etc. that are packed in large 200-liter drums, butter, margarine, etc. It can be liquefied in a short time of a few minutes after being placed on the cutting table, and the cumbersome work of changing the orientation of the drum to suit the natural environment, which is required in conventional natural thawing methods, can be done to suit the weather. This eliminates the need to adjust the schedule, and also eliminates the need to worry about the contents changing in quality due to abnormally high temperatures caused by convection.

〔Effect of the invention〕

The present invention is as described above, and it goes without saying that it is highly effective in fully achieving the intended purpose, but in particular, as described above, it is possible to liquefy one block in minutes. Not only does it have tremendous added value such as process improvement and cost improvement, but also, for example,
If the round-slicing process is omitted and a block the size of a large drum can be directly crushed by a crusher, the diameter of the rotating drum will naturally be increased and the number of expensive teeth will be increased geometrically. However, since the thawing machine used in the present invention is configured to cut a large drum-sized frozen food block into rounds and then crush it, the crusher has a rotating drum with a small diameter. Cheap ones are sufficient and have the advantage of being easy to carry out in terms of cost.Also, it is possible to consider a semi-manual method of cutting the block into rounds with a hand saw and then crushing it with a crusher; This method requires a lot of effort, is not suitable for the current situation, and is less practical than the method of the present invention.
