Embodiment 1

[0014] Such as figure 1 As shown, a cocoon evacuation steaming device described in this embodiment includes an outer barrel body 1 and an inner barrel body 2. The upper end of the outer barrel body 1 is an opening structure, and a sealing end cover 3 is arranged at the opening structure. The sealing end cover 3 and the outer barrel 1 are in a sealed state after they are closed, an inner barrel 2 is arranged inside the outer barrel 1, and there is a gap between the inner barrel 2 and the outer barrel 1, and the barrel wall of the inner barrel 2 There are a number of air holes in a uniform array, and a steam pipe 4 is arranged on the inner plate in the gap between the inner barrel body 2 and the outer barrel body 1, and the inlet pipe 5 and the air outlet pipe 6 of the steam pipe 4 pass through the outer barrel body 1. The bottom of 1 is provided with vacuum tube 7, is provided with vacuum pump 8 on vacuum tube 7, is provided with pressure gauge 9 on the vacuum tube 7 between va...

Embodiment 2

[0017] This example describes a method of using the equipment in Example 1 to evacuate cocoons and touch steam them. Put the cocoons into the mesh bag and place them inside the inner barrel, then close the sealing end cover to make the seal between the sealing end cover and the outer barrel body, and then Use a vacuum pump to evacuate the inside of the barrel, the evacuation pressure is 0.7MPa, then use the steam pipe to heat the inside of the barrel to 105°C, keep heating at 105°C for 7 minutes, then stop heating and let it cool down naturally for 7 minutes Finally, the material is discharged, and the cocoons taken out are left to stand for 24 hours under natural conditions in the room before entering the subsequent silkworm making process.

[0018] The silkworm making process is as follows: add the steamed cocoons into water, raise the temperature to 45°C, keep it warm for 1 minute, then raise the temperature to 100°C, keep it warm for 2 minutes, then lower the temperature to...

Embodiment 3

[0020] The difference between this example and Example 2 is that the silkworm production process is as follows: add the steamed cocoons into water, heat up to 45°C, keep warm for 2 minutes, then heat up to 99°C, keep warm for 3 minutes, then cool down to 70°C, keep warm 1min, and then put the cocoons into cold water, so that the temperature of the cocoons is lowered to below 20°C, and the silkworm making process is completed.

Abstract

The invention relates to the technical field of silkworm cocoon processing, in particular to a silkworm cocoon evacuation direct steaming device. The device comprises an outer barrel body and an innerbarrel body, a sealing end cover is arranged at an opening structure, the inner barrel body is arranged inside the outer barrel body, a plurality of vent holes are formed in the barrel wall of the inner barrel body in an uniform array, a steam pipe is arranged in the gap between the inner barrel body and the outer barrel body, and an evacuation tube is arranged at the bottom of the outer barrel body. The silkworm cocoon evacuation direct steaming method using the above device places silkworm cocoons into a net bag, then places the silkworm cocoons inside the inner barrel body, uses an evacuation pump to evacuate the inside of the outer barrel body, and conducts heating by the steam pipe, the taken silkworm cocoons are allowed to stand, and a follow-up silkworm production process is entered. The silkworm cocoon evacuation direct steaming device and the silkworm cocoon evacuation direct steaming method using the device can effectively improve the purity and yield of a silk yarn producedthrough the silkworm cocoons by a reasonable device structure design and a process design, and simultaneously make the level of the silk yarn reach 5A.

Description

technical field [0001] The invention relates to the technical field of silkworm cocoon processing, in particular to a cocoon vacuum touch steaming device and a silk cocoon vacuum touch steaming method using the equipment. Background technique [0002] In the prior art, it is difficult to fully cook the inner and outer silk in the silkworm making process due to the relatively large thickness of the cocoon and the uneven thickness of the cocoon, which affects the spinning effect and Finished product quality. Contents of the invention [0003] The object of the present invention is to provide a silkworm cocoon vacuum touch steaming device and a silkworm cocoon vacuum touch steaming method using the equipment, which can effectively improve the clarity of white factory silk. [0004] In order to achieve the above purpose, a silkworm cocoon evacuation and steaming device designed by the present invention includes an outer barrel body and an inner barrel body. The upper end of t...
