TECHNICAL FIELD

[0001] The utility model relates to agar crushing technical field, concretely to low temperature crushing equipment. BACKGROUND

[0002] Agar, also known as agar-agar, is a gelatin product made of algae genus and genus Gracilaria, which is the most commonly used solidifying agent for microbial culture medium, and is also used for canned meat, fish and poultry, cosmetics, pharmaceuticals and dental treatment. It has a wide range of applications in food industry, pharmaceutical industry, daily chemical industry, biological engineering and many other fields. During the extraction of agar, it needs to be crushed at low temperature by using a crushing device.

[0003] Defects: The existing low-temperature crushing device can only be crushed once, and it is difficult to ensure the crushing quality. The temperature of the raw materials gradually rises during crushing, causing a small amount of raw materials to melt, which causes the crushed agar to stick together.

[0004] In order to solve the above-mentioned defects, the prior art (Chinese patent with application number 202121457974.4 and application date of June 29, 2021) discloses a low-temperature crushing device for extracting agar. By setting the crushing motor, crushing roller and material receiving inclined plate, the agar raw materials can be preliminarily crushed and extruded, reducing the burden of subsequent crushing operation and improving the crushing effect of agar. By extruding between the crushing shaft and the steel grid, the crushing quality of agar can be ensured. By setting the liquid nitrogen tank and the conduit, the temperature of the agar raw materials in the crushing box and the crushing cylinder can be reduced, avoiding the adhesion of the crushed agar powder during the crushing process, which causes the production quality to not meet the use requirements.

[0005] The prior art drives the crushing knife to rotate by the crushing motor, which can crush the agar. At the same time, by extruding between the crushing shaft and the steel grid, the crushing quality of agar can be ensured. However, since the position of the crushing knife is fixed and cannot be adjusted, the agar located above the crushing cylinder cannot be fully crushed, resulting in poor crushing effect.

[0006] Therefore, we propose a low-temperature crushing device that can effectively solve the above problems. SUMMARY
