Description

Technical Field

[0001] The invention belongs to the technical field of silk protein extraction, and in particular relates to a device for extracting silk protein. Background Art

[0002] Development and utilization of silk protein in the field of cosmetics: Since silk protein is very similar to human skin keratin protein, the two have excellent affinity; due to the special chemical structure of silk protein molecules, silk protein has good hygroscopicity and moisture dissipation properties, can adapt to changes in the surrounding environment, play a natural role in humidity regulation, improve human skin nutrition, prevent skin wrinkles, enhance skin cell vitality and elasticity, promote cell metabolism and maintain normal physiological state of the skin; silk protein also has the function of absorbing ultraviolet rays and preventing solar radiation from damaging human skin, so silk protein and protein hydrolyzate - silk peptide (silk polypeptide) can be used as excellent additives for beauty cosmetics.

[0003] A Chinese patent specification with publication number CN205241579U discloses a silk protein extraction device, including an extraction tank, a heating device, and a stirring device in the extraction tank, the stirring device including a stirring rod rotating along the inner wall of the extraction tank and a motor driving the stirring rod to rotate. The unshredded silk cocoons are directly thrown into the extraction tank, the extraction tank is filled with an aqueous solution, and then the extraction tank is heated by the heating device. In this process, the stirring rod is driven to rotate by the motor, so that the stirring rod extending into the water surface can drive the aqueous solution to rotate, and at the same time, the silk cocoons are detached from the silk during the stirring process, so that the silk is wound around the stirring rod; the silk that has passed the degumming process does not need to be filtered during the hydrolysis process, avoiding the time spent on filtering the colloid in the later process, which is conducive to improving production efficiency.

[0004] However, this device for extracting silk protein has some shortcomings. First, after the silk is wound around the stirring rod, it cannot be automatically unwound. It needs to be manually unwound, which is cumbersome and difficult to operate. Second, the thermal inertia of the heating device is large, and it is not easy to control the heating temperature. Therefore, optimization and improvement are needed. Summary of the invention
