Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an antifreeze solution and a rapid freezing device for rapidly freezing agricultural and marine products and processed foods.

Conventional technology In recent years, agricultural and marine products and processed foods have been processed as frozen foods.
In many cases, it is sold after being pretreated and quickly frozen, and then kept in a refrigerator at a temperature of -18°C or less.

In a freezer that performs quick freezing, a cooler with a normal refrigeration cycle is installed inside the refrigerator, and the inside of the refrigerator is cooled to about -40'C while forcing convection with a fan.

Problems to be Solved by the Invention However, since the freezer freezes the frozen items while supplying cold air using a fan convection method, it takes a long time (approximately 24 hours) to freeze the items, and the freshness of the items deteriorates. There are drawbacks such as easy loss of energy, increased power consumption, increased equipment costs due to the need for a large space in the freezer, and high freezing processing costs.

In order to solve these problems, the present invention aims to provide an antifreeze solution and a quick freezing device that can freeze agricultural and marine products and processed foods in large quantities in a short period of time and at low cost. It is.

A foolproof way to solve problems Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

Reverse engraving 10.1 with attached reverse engraving 10.10'
A net conveyor 12 is formed by fixing a pushing plate 11 at the front and rear endless chains 7, 7 of the net conveyor 12.
' are fitted into the chain guides 4, 4' of the freezing tank 2, and are placed around the chain wheels 6 of each rotating shaft 5 to cause the net conveyor 12 to circulate from inside the freezing tank 2 via the lower part of the freezing tank 2, The third rotating shaft 5c and the prime mover 13 installed in the machine frame 1 are interlocked, and the stirring blade 14 is pivotally supported on the inner surface of the freezing tank 2 to interlock with the prime mover 15. A suction pipe 17 extending from the oil cleaner pump 16 and a circulation inflow pipe 18 are connected to each other at a position closer to the side, and an antifreeze solution for quick freezing mainly composed of ethyl alcohol and distilled water is stored in the freezing tank 2 and frozen. A cooler 19 is installed inside the tank 2 and connected to an external refrigeration mechanism, or a circulation pipe for circulating the quick freezing antifreeze in the refrigeration tank 2 to an external refrigeration system is connected to the refrigeration tank 2. This is to constitute the rapid freezing device 20. Note that 21 in the figure indicates a chute.

Actions and Effects The antifreeze solution for quick freezing of the present invention contains ethyl alcohol and distilled water as main components. Ethyl alcohol is used as a raw material for the synthesis of solvents, fuels, and chemicals, and as an alcoholic beverage. Its melting point is -114°C. Antifreeze, which is harmless to the human body, can be obtained by mixing ethyl alcohol with distilled water. It is possible. The silicone powder acts as a stabilizer, polypurine glycol as a preservative, sodium malate as a sweetener, fatty acid ester as a surfactant, glycine as an aminoacetic acid, and phytic acid as an anti-discoloration agent. Yes, this antifreeze is 13 times
It is possible to directly freeze packages of agricultural and marine products and processed foods by immersing them inside the container when cooled to below 0°C.As an example, the weight ratio of each component is shown in the table below. Become.

The quick freezing device 20 for freezing agricultural and marine products and processed foods using the quick freezing antifreeze having the above structure has a freezing tank 2 built inside the machine frame 1 as shown in the drawing, and the lower part of the tank is opened from inside the tank. The antifreeze solution for quick freezing stored in the freezing tank 2 is kept at -30°C or below by using a cooler 19 or by circulating it to an external freezing device. After cooling, the net conveyor 12 is transferred using the prime mover 13 in the machine frame 1.
is rotated as shown by the arrow in FIG. The antifreeze liquid is immersed into the antifreeze solution. The items to be frozen are frozen while passing through the antifreeze liquid that has been cooled to below -300C, and as the net conveyor 12 ascends on the right side of the freezing tank 2 and moves to the base plate 3', the items to be frozen are placed inside the antifreeze liquid. When the net conveyor 12 is turned downward at the position of the second rotating shaft 5b at the side end, the frozen products are sequentially discharged into the chute 21, and the frozen products that have been frozen are sequentially discharged into the chute 21. The product should be stored directly in the refrigerator. A stirring blade 14 is provided in the freezing tank 2 to stir the antifreeze to a uniform temperature and circulate the antifreeze to the oil cleaner pump 16 to remove oil that flows into the antifreeze while the net conveyor 12 is rotating. It is possible to prevent products to be frozen from being contaminated with oil, and it is possible to freeze a large amount of products in a short period of time without requiring a large space compared to conventional blow freezing using a freezer. It has the remarkable effects mentioned above, such as saving electricity and other expenses, and since it uses antifreeze, the freshness of fresh foods can be dramatically improved compared to conventional methods. be.
