A kind of cocoon cooking device and cocoon cooking method

Abstract

The invention discloses a cocoon cooking device and a cocoon cooking method, and relates to the technical field of textile reeling. The cocoon cooking device of the present invention includes a cocoon cooking bucket and a vacuum exhauster, the vacuum suction machine is arranged outside the cocoon cooking bucket and communicated with the cocoon cooking bucket; The cocoon hopper and the cocoon feeding channel, the cocoon feeding hopper is set on the outer top wall of the cocoon cooking barrel, the cocoon feeding channel is set inside the cocoon cooking barrel; The cocoon passage and the cocoon entry passage are provided with a cocoon separation passage. The cocoon separation passage has an inlet and an outlet. The cocoon cooking method of the present invention is based on the above cocoon cooking device. In the present invention, silkworm cocoons are automatically placed in layers, realizing the integration of layering and cocoon cooking, and improving the efficiency of cocoon cooking; by balancing water temperature and negative pressure penetration, the phenomena of sheet ripeness, superficial ripeness and spot ripeness are avoided, and the quality of raw silk is guaranteed.

Description

technical field [0001] The invention relates to the technical field of textile reeling, in particular to a cocoon cooking device and a cocoon cooking method. Background technique [0002] Silkworm cocoons are the raw material for silk making. The process of peeling silkworm cocoons into raw silk is called silk making. The silk making process often includes cocoon drying, cocoon peeling, cocoon selection, cocoon cooking, silk reeling, reshaking, and finishing. Dry cocoons cannot directly peel off cocoon threads in sequence. Due to the unique way of silkworms spinning cocoons, the cocoon threads are arranged in an "S" shape and an "8" shape, forming many overlapping points, and the cocoon layer is formed from the outer There is a difference in sericin content in the cocoons, which makes part of the cocoon silk more heavily glued and difficult to dissociate. After the silkworm cocoons are dried and stored, the sericin of the cocoon layer is glued more firmly, and the adhesive ...

AI Technical Summary

Problems solved by technology

This method of cocoon cooking has many disadvantages. First, all procedures are done manually, resulting in low efficiency of cocoon cooking. Second, it is extremely easy to cause uneven heating, resulting in flakiness (cooking difference between cocoons) Third, the water absorption capacity and water penetration ability of silkworm cocoons are different, resulting in the phenomenon of superficial cooking (cooked outside the cocoon layer and raw inside) and spotted cooking (uneven cooking of different parts of the cocoon grains)
