Abstract

The invention discloses a layered cocoon cooking method, relating to the technical field of cocoon processing. The layered cocoon cooking method comprises the steps of (A) soaking, namely putting cocoons into purified water of 40-50 DEG C, soaking for 3-5 minutes and fully moistening the cocoons; (B) cooking, namely putting the cocoons on a layered cocoon cooking device, putting the layered cocoon cooking device with the cocoons into a cocoon cooking pot containing the purified water for cooking, further cooking for 5-8 minutes after the purified water in the pot reaches a boiling state, and fully defibering the cocoons; and (C) cooling, taking out the cocoons cooked in the step (B) and the layered cocoon cooking device, putting the cocoons and the layered cocoon cooking device into a container containing the purified water at 50-60 DEG C for 3-5 minutes, cooling the cocoons, and further swelling and properly dissolving cocoon layer sericin. Compared with the prior art, the layered cocoon cooking method has the advantage that the problem of uneven cocoon defibering when the cocoons are cooked can be solved.

Description

technical field

[0001] The invention relates to the technical field of silkworm cocoon processing, in particular to a layered cocoon cooking method. Background technique

[0002] Cocoon cooking is a key process in the silk making process. The quality of cocoon cooking not only directly affects reeling and unwinding, but also affects various indicators related to raw silk quality, such as deviation, cleanliness, cleanliness, and raw silk cohesion. ; Due to limited production conditions, many silk reeling factories cannot use cocoon cooking equipment with high automation procedures. Because silkworm cocoons are affected by the physical properties of silkworms and the cocooning environment, as well as the influence of storage and transportation, the quality of silkworm cocoons is uneven and the size is uneven when they enter the silk reeling factory. Therefore, the time and temperature requirements for cocoon cooking are different. Moreover, during the heating process of the c...

Examples

Embodiment 1

[0016] A layered cocoon cooking method using a method such as figure 1 and figure 2 The layered cocoon cooking device shown includes a support column 1 with a limit block 2 at the bottom. The support column 1 is sequentially set with a plurality of cocoon trays above the limit block 2. The cocoon tray is provided with The disk surface 3, and the surrounding edge 4 vertically extending downwards from the edge of the disk surface 3, the disk surface 3 and the surrounding edge 4 are all provided with a plurality of through holes 5; the height of the surrounding edge 4 is greater than or equal to the height of the limit block 2, and the supporting column 1 is fitted with a handle 6 at the top;

[0017] This layered cooking cocoon method comprises the following steps:

[0018] A. Soaking: Soak the cocoons in pure water at 40°C for 3 minutes to fully moisten the cocoons;

[0019] B. Cooking: place the silkworm cocoons on the layered cocoon cooking device, and place the silkworm ...

Embodiment 2

[0022] A layered cocoon cooking method, using the same layered cocoon cooking device as in Example 1;

[0023] This layered cooking cocoon method comprises the following steps:

[0024] A. Soaking: Soak the cocoons in pure water at 50°C for 5 minutes to fully moisten the cocoons;

[0025] B. Cooking: place the silkworm cocoons on the layered cocoon cooking device, and place the silkworm cocoons on the disk surface 3 of the cocoon tray at different positions according to the thickness and size of the silkworm cocoons, and place the thicker and larger ones At the bottom layer, the thinner and smaller cocoons are placed on the top layer, and the number of cocoons placed on each layer is evenly spaced, and then the layered cocoon cooking device with silk cocoons is placed in a cocoon cooking pot filled with pure water for cooking. After the pure water in the pot reaches boiling state, continue to cook for 8 minutes to fully dissolve the cocoons;

[0026] C. Cooling down: take ou...
