Cocoon cooking water absorption adjusting device in vacuum state and control technology thereof

Abstract

The invention discloses a cocoon cooking water absorption adjusting device in a vacuum state and a control technology thereof. The device comprises a vacuum water absorption adjusting device and an electric control cabinet control device in control connection with the vacuum water absorption adjusting device, and the vacuum water absorption adjusting device comprises a temperature probe, a water tank, a pipeline, a main tank, an auxiliary tank and electric control equipment composed of a one-way valve, a water pump, a vacuum pump and a plurality of electromagnetic valves; the electric controlcabinet control device comprises an electric control cabinet body, a PLC main board is arranged in the electric control cabinet body, a PLC text displaying screen, an automatic running switch and an automatic / manual change-over switch are arranged on the electric control cabinet body; the control technology comprises the steps that vacuumizing is conducted, and high-temperature water is sucked; vacuumizing is conducted, and low-temperature water is sucked; vacuumizing is conducted, and normal-temperature water is sucked; vacuumizing is conducted, and the normal-temperature water is continuously sucked; air releasing and re-pressing are conducted, and silkworm cocoon water absorption adjusting temperature reducing protection is completed; the device is in a closed cocoon cooking container,water absorption adjusting for cocoons is completed in the vacuum state, and the control technology can make the cocoons uniformly absorb water and reduce the generation rate of shriveled cocoons.

Description

technical field [0001] The invention relates to the fields of cocoon cooking technology and the like, specifically, a device for cocoon cooking to adjust water absorption in a vacuum state and a control process thereof. Background technique [0002] Cocoon cooking is an important production process of silk reeling. Cocoon cooking is to make the cocoon cocoon layer sericin properly swell and dissolve through the water medium under a certain temperature or pressure state, so as to weaken the adhesive force between the cocoon threads, and the cocoon threads can be dissociated in turn. process. The degree of ripeness of boiled cocoons affects the smoothness of silk reeling, which in turn affects the quality of raw silk, raw material cocoon consumption, and the completion level of output. [0003] The cocoon cooking process includes three processes: infiltration, cooking, and adjustment and protection. At present, the external vacuum infiltration + stainless steel long cage coco...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to design a device for cooking cocoons in a vacuum state to adjust water absorption and its control process. The device can solve the shortcomings of the prior art such as uneven water absorption, easy generation of cocoons, poor cleaning performance, and large water consumption. , in the closed cocoon cooking container, using vacuum technology, the cocoons can adjust the water absorption in a vacuum state, reduce the production rate of cocoons, can produce raw silk with high cleanliness, and reduce water consumption. In the device The control process realized on the basis of can make the cocoons absorb water evenly and reduce the production rate of shriveled cocoons
