3 results about "Antheraea pernyi" patented technology

The invention provides an antheraea pernyi fresh-keeping method which comprises the following steps: S1, dividing a first group and a second group with different freezing response characteristics according to development biological characteristics of antheraea pernyi; the freezing response characteristic is represented by at least one parameter of tissue moisture content, methylene blue penetration depth and body wall elasticity modulus; s2, differential preprocessing is applied to the first group and the second group, so that the difference of the first group and the second group on any characterization parameter does not exceed a preset threshold value; s3, combining the two groups of tussah and freezing; in the first cooling stage, cooling from 0-1 DEG C to-10 DEG C at the speed of 0.8-1.2 DEG C / min; in the second cooling stage, cooling is conducted from-10 DEG C to-30 DEG C at the speed of 0.45-0.55 DEG C / min; in the third cooling stage, cooling from-30 DEG C to-45 DEG C at the speed of 1.8-2 DEG C / min; and S4, after freezing is completed, vacuum packaging is performed, and storage is performed at minus 45-minus 40 DEG C. According to the fresh-keeping method for the tussah, the integrity of a cell structure is maintained, juice loss is reduced, and abnormal release of endogenous enzyme is inhibited, so that nutritional ingredients are better reserved in the long-term freezing storage process, and the sensory characteristics of compact meat, uniform color and luster and no peculiar smell are maintained.

This utility model relates to an automatic unwinding device for live tussah silkworm pupae, including an unwinding liquid tank. A drive motor is installed at one end of the unwinding liquid tank, and the output shaft of the drive motor extends into the device housing and connects to a roller. Multiple first leakage holes are opened on the surface of one end of the roller, and multiple cocoon-filling grids are opened on the surface of the roller. Fresh tussah silkworm cocoons are loaded into the cocoon-filling grids on the surface of the roller. This utility model has the ability to operate stably in low temperature and normal pressure environments, can automatically achieve constant temperature control, and can automatically rotate to allow fresh tussah silkworm cocoons to enter and exit the low temperature alkaline unwinding liquid, thereby ensuring that the pupae inside the cocoons can obtain sufficient oxygen supply. Its heating has a temperature control function, which can effectively ensure the unwinding effect of the alkaline solution. In addition, it is more flexible and mobile, improving production efficiency and reducing resource waste while having lower requirements for working environment conditions.
