Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulverizing devices, in particular to a low-temperature pulverizing device for extracting agar. Background Art
[0002] Agar is a natural polysaccharide extracted from a specific type of seaweed. Due to its excellent gel-forming ability and stability, it is widely used in various industries, including food, medicine, and cosmetics. In the food industry, agar is used as a thickener, stabilizer, and coagulant in products such as jellies, puddings, and candies, providing a unique taste and texture. Agar is also used as a base material for microbial culture media, supporting the growth of various bacteria and fungi. Because it is non-toxic, odorless, and has good biocompatibility, agar is also used in the pharmaceutical field to prepare capsules and tablets. Agar extraction typically involves washing the algae, boiling, cooling, filtering, and drying.
[0003] Currently, the main method for preparing agar is the acid-base method. Although the acid-base method is effective for extracting agar, it has many problems: large amounts of acid and alkali are used, large amounts of water are consumed for cleaning, a heavy environmental burden is imposed, and the production cycle is long. More importantly, under high temperature conditions, acids and alkalis can easily destroy the molecular structure of agar, leading to the loss of colloid and reduced yield. These problems not only increase production costs but also place a heavy burden on the environment. Compared with the traditional acid-base method, the oxidation method for extracting agar greatly reduces production costs and environmental pollution, making the production of agar greener and more sustainable. In addition, agar extracted by the oxidation method shows excellent performance in the paraffin double embedding method, which broadens the application range of seaweed and agar, increases the utilization value of both, and thus promotes the development of the seaweed industry.
[0004] Currently, the low-temperature pulverization equipment available on the market is often only capable of a single pulverization process. This not only makes it difficult to ensure the fineness requirements of the final product after oxidation processing, but also as the pulverization time increases, the material temperature gradually rises, which may cause some agar to melt and stick to each other, seriously affecting the quality of the finished product after oxidation processing. For example, in the food industry, agar with uneven particle size may affect the taste and texture of the product; in the pharmaceutical field, uneven particle size may affect the release rate and stability of the drug. In addition, the increase in material temperature can also trigger a series of adverse reactions, such as the breakage or cross-linking of agar molecular chains, reducing its gel strength and solubility. High temperature may also promote oxidation reactions, resulting in darkening of color and the generation of off-flavors, further affecting the sensory quality of the product. Utility Model Content

The partition 8 separates the cooling pipe 7 into a cold chamber and a hot chamber. The cold chamber and the hot chamber are connected through the water hole. A pumping assembly and a refrigerator 14 are connected to the water tank 9. The pumping assembly is connected to the cooling pipe 7. A temperature display 15 is installed on the side of the water tank 9 away from the mounting frame 4. The temperature display 15 can monitor and display the temperature in the water tank 9 in real time. A filter 16 is fixedly connected to the bottom of the mounting frame 4. A suction device 17 is installed at the bottom of the mounting frame 4. The bottom of the suction device 17 is fixedly connected to a suction pipe 18. The top of the suction device 17 is fixedly connected to a discharge pipe 19. The suction pipe 18 passes through the outer wall of the mounting frame 4, and the discharge pipe 19 is connected to the blanking rack 2.
[0022] like Figure 2-Figure 4 As shown, the pumping assembly includes a first water pump 10, a water inlet pipe 11, a second water pump 12 and a water outlet pipe 13.
