Description

A silkworm cocoon drying device

technical field

The utility model relates to the field of silk processing equipment, in particular to a cocoon drying device.

Background technique

Silkworms include mulberry silkworm, tussah silkworm, castor silkworm, cassava silkworm, willow silkworm and celestial silkworm. The thread drawn from a single silkworm cocoon is called cocoon silk. It is made of two single fibers bonded by sericin. When reeling, the cocoon silk of several silkworm cocoons is pulled out and bonded into silk strips by sericin, which is collectively called silk. Silk without sericin is called refined silk. Mulberry silk is the most used silk, followed by tussah silk, and other silks have not formed resources due to their limited quantity. Silk is light and slender, with good luster, comfortable to wear, smooth and plump hand feeling, poor thermal conductivity, moisture absorption and breathability.

In the process of silk making, heat energy is used to kill the living silkworm chrysalis in the cocoon cavity of the fresh cocoon, remove appropriate amount of water, and dry the fresh cocoon into a dry cocoon, 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. During the drying process of silkworm cocoons, reasonable temperature, humidity and wind speed should be adopted according to the characteristics of silkworm cocoons, so as to avoid excessive denaturation of sericin, achieve suitable and uniform drying, and preserve cocoon quality.

Utility model content

The purpose of the utility model is to provide a silkworm cocoon drying device, in order to dry the silkworm cocoons uniformly and without affecting the unwinding of the silkworm cocoons.

In order to solve the technical problems described in the background technology, the utility model adopts the following technical solutions:

A silkworm cocoon drying device, comprising a preheating chamber, a drying oven and a cooling chamber, a heating layer is arranged inside the preheating chamber, a runner is arranged in the center of the preheating chamber to drive the cocoons; A rotating shaft is arranged at the axis position, and one end of the rotating shaft is connected to a motor that drives it to rotate through a bearing; rotating blades are arranged on the outside of the rotating shaft; an air inlet connected to a fan is arranged at the bottom of the drying box, and an air inlet is connected to the top of the fan. One side is connected to an air outlet at the bottom of the drying box through an air duct; the bottom of the drying box is connected to one end of the feeding pipe through a feeding valve, and the other end of the feeding pipe is connected to a cooling chamber; one end of the cooling chamber is connected to a cooling fan.

Further, a feeding device is provided on the top of the preheating chamber, and silkworm cocoons enter from the top of the preheating chamber.

Further, the same position of the heating layer and the shell of the preheating chamber is provided with a discharge port for cocoon discharge, and a discharge valve that can be toggled to discharge is provided at the discharge port, and the preheating chamber One end is connected to the drying box through the discharge port. After the cocoons are decomposed by the residual heat, the discharge valve is opened, and the cocoons are brought into the drying box as the runner rotates.

Further, the drying box is inclined downward at an angle, which is convenient for the silkworm cocoons to be transferred to the cooling room after being dried.

Further, the air inlet and the air outlet are covered with screens to prevent silkworm cocoons from entering the air duct and fan.

Further, the air duct is provided with a heating device to heat the air to perform circulating air-heat drying on the drying box.

The beneficial effects of the utility model are:

1), drying evenly, the three processes reduce the waste of silkworm cocoons;

2) Save energy and use thermal cycle for drying.
