Device and method for silkworm cocoon vacuum penetration treatment

Abstract

The invention discloses a device and a method for silkworm cocoon vacuum penetration treatment. A vacuum tank consists of a cylindrical tank body (4) at the upper part and a conical tank body (5) at the lower part; an upper end cover (6) is arranged at the top of the vacuum tank; a lower end cover (7) is arranged at the bottom of the vacuum tank; a vacuumizing port (10) and a jet orifice (11) are formed on the wall of the vacuum tank; the vacuum tank further comprises a pressure meter (12); and a pressure sensor of the pressure meter (12) is arranged inside the cavity of the vacuum tank. By making full use of negative pressure of the vacuum tank, a cocoon cavity can absorb adequate water and a silkworm cocoon is relatively heavy and crude, so that the silkworm cocoon vacuum penetration treatment device is applicable to automatic silk reeling; the silkworm cocoon vacuum penetration treatment device is quick in penetration and high in efficiency, and the efficiency is 2 / 3 higher than the efficiency of a circulating steam cocoon cooking method; a cocoon cooking worker can easily operate and master the silkworm cocoon vacuum penetration treatment device and can finish the vacuum penetration without walking back and forth for observing; the labor is saved, and the labor intensity of working staff is reduced; and energy is saved, consumption is lowered and benefits are increased.

Description

technical field [0001] The invention relates to a cocoon vacuum infiltration treatment device and method. Background technique [0002] At present, the method of cocoon cooking in silk reeling factories is to use a circulating train box type or a disc cocoon cooking machine, that is, manually dig out the dried cocoons with a scoop, pour them into the cages arranged on the cocoon cooking machine and cover them, and drive them through the rotation of the motor. The chain of the cocoon cage runs in a cycle, passing through the high-temperature penetration part, the low-temperature penetration part, the cocoon cooking chamber, the reclaimed water part, the adjustment part and the exit part in the sealed box of the cocoon cooking machine in sequence, and the cocoon cage automatically opens the cooked cocoon at the cocoon connection point Fall into the Cocoon Bucket. The whole cocoon cooking process relies on a large amount of steam to heat the cocoons. This traditional method ha...

AI Technical Summary

Problems solved by technology

[0003] 1. It is more suitable for the original vertical silk reeling, but not suitable for automatic silk reeling machines;

[0004] 2. The output of cocoon cooking is low and the time is long. Because there are 120 cocoon cages in the circulation type cocoon cooking, it takes 5 minutes to turn around for a week, and each cocoon cage holds 0.08kg, so the cocoon cooking output is only 100kg / hour;

[0006] 4. Silkworm cocoons are boiled in six parts, resulting in a dissolution rate of more than 5% of sericin, which increases consumption;

[0007] 5. One person needs to dig cocoons, one person needs to cook the cocoons to adjust the air pressure and water temperature, and one person needs to pick up the cocoons, and the labor intensity of the workers is high, the efficiency is low, and the production cost is virtually increased.
