Cocoon cooking device and process capable of enabling cocoon cavity not to contain water

Abstract

The invention discloses a cocoon cooking device and a cocoon cooking process capable of enabling a cocoon cavity not to contain water. The device comprises a main tank, a plurality of system pipelines, a plurality of electromagnetic valves, an auxiliary tank, a vacuum pump, a steam inlet and a liquid water inlet, wherein the steam inlet and the liquid water inlet are formed in the system pipelines. The cocoon cooking process comprises the following steps of permeating, cooking, adjusting and protecting, wherein a separate cocoon cavity dewatering step is added between the permeating step and the cooking step, so that cocoon cavity dewatering and cooking are separated into two separate steps, and the cocoon cavity is subjected to dewatering in the cocoon cavity dewatering step in a manner that the main tank for cocoon cooking is subjected to vacuumizing depressurization; the temperature is kept constant during the vacuum depressurization dewatering of the cocoon cavity of a silkworm cocoon. The condition that the cocoon cavity is completely free of liquid water can be reached, and the technical problems that steam heat cannot be uniformly conducted, a cocoon layer of the silkworm cocoon is heated unevenly, and the like are avoided.

Description

technical field [0001] The invention relates to a cocoon cooking device and process. [0002] Background technique [0003] The existing cocoon cooking equipment is equipped with "vacuum osmosis machine + stainless steel circulating cocoon cooking machine" as standard configuration. The cocoon absorbs water in the cocoon cavity in the vacuum osmosis machine, and then the cocoons are sprayed and boiled in the water spouting part and cooking part of the circulating cocoon cooking machine. Cooking process. [0004] At present, the cocoon cooking process has a cooking step. The main function of this step is to spit out water from the cocoon cavity and cook the cocoon layer. Due to the structural limitations of the current circulating cocoon cooking machine, the water spit out of the cocoon and the cooking of the cocoon layer are simultaneously completed in this step. There are obvious defects; the water spit process of the cocoon is to use the temperature difference between th...

AI Technical Summary

Problems solved by technology

[0009] The present invention overcomes the deficiencies of the prior art, provides a cocoon cooking device and process without water in the cocoon cavity, and solves the problems in the prior art that water spouting from the cocoon cavity and cocoon cooking are carried out at the same time, and the drainage of the cocoon cavity is insufficient during cocoon cooking. , Uneven cooking and other problems
