Reciprocating stirring device for drying silkworm cocoons

Abstract

The invention provides a reciprocating stirring device for drying silkworm cocoons and belongs to the technical field of drying equipment. The reciprocating stirring device for drying the silkworm cocoons comprises a top plate, a left vertical plate, a right vertical plate, a bottom plate and a drying box; the left vertical plate is welded to the lower left of the top plate, and the right verticalplate is welded to the lower right of the top plate; a rotating shaft penetrates the top plate, and an external thread is arranged on the middle shaft segment of the rotating shaft; and the bottom ofthe left vertical plate is fixedly connected to the upper left of the bottom plate, and a left slide rail is welded to the inner side of the left vertical plate. According to the reciprocating stirring device for drying the silkworm cocoons, a driving motor is started to rotate forwards, the rotating shaft is controlled to rotate, a connecting sleeve screwed to the threaded segment on the rotating shaft drives the driving box to move downwards, the drying range of the silkworm cocoons is increased, meanwhile, stirring blades are used for stirring the silkworm cocoons, evaporation of water inthe silkworm cocoons is accelerated, and the drying efficiency is improved; and when the rotating shaft and the connecting sleeve are about to be unscrewed, the driving motor is started and rotates reversely, the drying box is made to move upwards, and the silkworm cocoons can be repeatedly and thoroughly dried.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a reciprocating stirring device for cocoon drying. Background technique [0002] The drying of silkworm cocoons is the process of using heat energy to kill live silkworm chrysalis in the cocoon cavity of fresh cocoons during the silk making process, and remove appropriate amount of water, and dry the fresh cocoons into dry cocoons, commonly known as cocoon drying. The purpose of drying is to prevent the live pupae from turning into moths during the cocoon storage period, the parasitic fly eggs left by the silkworm body from maggots and pupae from rotting to damage the cocoon layer, and at the same time make the cocoon layer properly change the soluble properties of the outer sericin after heat treatment. Enhance cocoon boil resistance, protect cocoon unwinding, and facilitate silk reeling and storage. In the drying process of silkworm cocoons, a reasonable drying method...

AI Technical Summary

Problems solved by technology

In the drying process of silkworm cocoons, a reasonable drying method should be adopted according to the characteristics of silkworm cocoons to avoid excessive denaturation of sericin, achieve suitable drying and uniformity, and preserve the quality of cocoons. In the prior art, high-temperature drying is used when drying silkworm cocoons However, this kind of method will cause problems such as uneven heating of the participants, large gap between cocoon temperature and ambient temperature after drying, resulting in moisture regain, sudden cooling and discoloration, etc., so there is an urgent need for a drying device that can make cocoons evenly heated to meet current needs.
