Description
Technical Field
The invention relates to the field of raw silk production, in particular to silkworm cocoon pretreatment equipment. The invention also designs a silkworm cocoon pretreatment process.
Background
The silkworm cocoon generally refers to a silkworm cocoon, i.e. a capsule-shaped protective layer in the pupal stage of the silkworm, which contains a pupal body, and the protective layer comprises a cocoon shell, a pupal lining and the like. Sericin in the silkworm cocoon is a globular protein, is generated in the middle silk gland of a silkworm body, irregularly coats the surface of fibroin entering a middle silk gland cavity from the rear silk gland in a scaly manner, and is stored in the gland cavity, and accounts for about 25% of the total weight of the cocoon silk. Sericin has a protective effect on silk fibroin, but too much sericin affects the luster and hand feeling of silk and also affects the bleaching effect of silk, resulting in uneven dyeing, so that the sericin on the silk must be removed. The existing silk degumming method mainly comprises the following steps: boiling in water bath to remove colloid, removing colloid with sodium carbonate, removing colloid with neutral soap, removing colloid at high temperature and high pressure, and removing colloid with enzyme. However, the existing silkworm cocoon pretreatment equipment cannot distinguish and sort the silkworm cocoons with different degumming degrees, so that the silkworm cocoons with different degumming degrees flow into the next processing procedure together, which can cause the quality levels of finished products made of the silkworm cocoons with different degumming degrees to be uneven.
Chinese patent CN86204267 discloses a pretreatment device before silk reeling for producing silk, which comprises an intermittent silk cocoon metering feeder, a silk cocoon cooking pot, a conveying belt obliquely arranged in the pot, and a cocoon beating device. The walls of the pot are arranged parallel to the edges of the conveyor belt and are spaced apart from the transverse bars on the conveyor belt at equal distances by a gap, which transverse bars are made as brushes. The conveyor belt may be provided with a stepwise movement which allows the friction between the cocoons and the walls of the cocoon cooking pot and the brushes on the conveyor belt to be increased when the cocoons are immersed in the cocoon cooking pot. Thus, the processes of boiling the silkworm cocoons and finding the silk heads on the silkworm cocoons can be completed simultaneously.
