The inside of the large-diameters pipe (20) has a second space created for loading liquid or gas (12). The small-diameter pipe(10) is installed at the center of the large-diameter pipe (20). Part of the large-diameter pipe(20) has an input pipeline (30B) functioning to transport liquids into the second space for containing liquid or gas (12). Part of the large-diameter pipe (20) has an outlet pipe (40A) functioning to transport liquids into the second space for containing liquid or gas (12).

Description
STRUCTURE OF A REFRIGERANT PIPE FOR FREEZING LIQUIDS
Branch of Science Related to the Invention
Engineering in the parts involving the structure of a refrigerant pipe for freezing liquids
Background of Related Arts or Sciences
In reference to making liquids gelatinous, particularly beer as in previous inventions, the method of accelerating the lowering of the temperature in the refrigerator and waiting for 20-50 minutes until beer becomes gelatinous and is consumed has disadvantages from taking a long time and wasting time in addition to wasting energy and refrigerators cannot be carried offsite.
The structure of the refrigerant pipe for freezing liquids in this invention has a parallel pipe structure and uses gas to transfer coldness via the pipe to the liquid in order to change the liquid’s state into a solid or gelatinous substance in 3-10 seconds by using principles of air conditioning systems and gas from evaporator pipes to create convenience, ease of use and portability.
Description and Purpose of the Invention
The refrigerant pipe for freezing liquids is composed of a small-diameter pipe. The interior of the small-diameter pipe has the first space for containing liquid or gas. The large- diameter pipe’s interior has the second space for containing liquid or gas. The small-diameter pipe is installed in the center of the large-diameter pipe. One part of the large-diameter pipe has an inlet pipe functioning to transport liquids into the second space for containing liquid or gas. One part of the large-diameter pipe has a outlet pipe functioning to transport liquids from the second space for containing liquid or gas. One part of the small-diameter pipe has an inlet pipe functioning to transport gas into the first space for containing liquid or gas. One part of the small-diameter pipe has an outlet pipe functioning to transport gas from the first space for containing liquid or gas. The liquid will come into contact with the small-diameter pipe which has gas making the small-diameter pipe cold. The liquid will come into contact with the small-diameter pipe and abruptly change states from a liquid to a solid or a gelatinous substance. The solid or gelatinous substance will exit via the outlet pipe in 3-10 seconds.
The purpose of this invention is to have a structure for a refrigerant pipe for freezing liquids with a parallel pipe structure that uses gas to transfer coldness via pipes to liquids in order to change the state of the liquid into a solid or gelatinous substance abruptly in 3-10 minutes.
