Description
Technical Field
The invention relates to the technical field of silkworm cocoon processing, in particular to a cocoon cooking method for silkworm cocoons.
Background
Cocoon cooking is a key process in the silk making process. The cocoon cooking quality can directly influence reeling folding and reelability, and can also influence various indexes related to raw silk quality, such as deviation, cleanness, cleanliness, raw silk cohesion and the like. Of course, cocoon cooking also affects the average fineness of raw silk. The reason for the influence is generally analyzed from the perspective of improving the cocoon reelability in cocoon cooking, and the cocoon reelability after cocoon cooking is considered to be good, the inner layer thread drop is reduced, the utilization rate of the inner layer cocoon silk is improved, and the average fineness of raw silk is reduced. The process is characterized in that sericin on the periphery of cocoon filaments is properly swelled and dissolved by the action of water and heat (sometimes chemical additives are added). Cocoon cooking weakens the adhesive force among cocoon filaments, is beneficial to reeling silk and is an important process in the silk making process.
However, in the existing cocoon cooking process, cocoon cooking is easy to be over-cooked, sericin is excessively lost, and reeling folding is increased, so that the subsequent reeling process cannot be smoothly carried out.

Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is in no way intended to limit the invention.
A cocoon cooking method of silkworm cocoons comprises the following steps:
s1, cocoon selection: classifying the fresh cocoons in grades, removing inferior cocoons and rotten cocoons, and gathering the intact fresh cocoons for subsequent treatment;
s2, immersion treatment: soaking fresh cocoon in purified water of 40-60 deg.C for 30 min;
s3, infiltration treatment: taking out the soaked silkworm cocoon, putting the silkworm cocoon into a penetration device, and performing reduced pressure penetration in a vacuum environment at 50 ℃;
s4, performing catalytic distillation: placing the infiltrated silkworm cocoon into a vacuum cylinder, vacuumizing, introducing high-temperature steam into the vacuum cylinder, and sealing the silkworm cocoon for heat preservation for 15-20 min;
s5, cocoon cooking treatment: placing the silkworm cocoons subjected to the touch steaming treatment into a cocoon cooking machine for cooking, dripping a reeler into the cocoon cooking machine at the flow rate of 30 drops per minute in the cooking process, and keeping the temperature at 90-95 ℃;
s6, cocoon outlet: and taking out the cocoons subjected to cocoon cooking treatment, cooling to room temperature, and then sending to a silk reeling workshop.
As an example of the present invention, a,
in step S2, purified water is first heated to 40-60 ℃, and then fresh cocoons are layered and soaked in purified water for 30 min.
As an example of the present invention, a,
in step S3, cocoons are placed in the penetration device and sealed closed, and then the inner chamber of the penetration device is vacuumed and then warmed to 50 ℃.
As an example of the present invention, a,
in step S4, the thin-head cocoons in middle and late autumn adopt the technological parameters of 100 ℃ and 20min of contact steaming;
for spring cocoons, the technological parameters of contact steaming at 105 ℃ for 20min are adopted.
As an example of the present invention, a,
in step S5, after the cocoon cooking is completed, the cocoon cooking machine is acted by the ultrasonic generator, and the cocoon is discharged after 5min of action.
The working principle and the beneficial effects of the technical scheme are as follows: the cocoon cooking is a process of cooking the silkworm cocoons produced by spinning the silkworms. Cocoon cooking is a process in a silk cocoon spinning process, and is one of the most important pre-processes for silk reeling.
Because the silkworm cocoons are difficult to achieve the purposes of uniform cooking and effective production due to the difference of factors such as variety, growth environment, cleanliness, storage treatment and the like, the difference of the silkworm cocoons is reduced and the cooking penetration uniformity of the silkworm cocoons is improved by adopting a method for increasing a cocoon cooking pretreatment process. The common cocoon cooking pretreatment methods generally comprise cocoon selection, dipping treatment, permeation treatment and touch steaming treatment. The pretreatment process for boiling cocoon can well improve the quality of the obtained raw silk, improve the yield and the quality of reeling silk and maximize the effective utilization of the raw material cocoon. Wherein the touch steaming treatment is mainly used for improving the cleanliness of raw material cocoons and reducing silk reeling failures after cocoon cooking. The method of wet-heat pretreatment of dry cocoons in saturated steam before boiling is called a touch steaming treatment. Steam is mainly used for processing the cocoon layer in the steam contact treatment, and steam molecules are small and can easily permeate to all parts of the cocoon layer, so that the cocoon layer can permeate more uniformly, the hydrophilicity of the cocoon layer is improved, the water absorption capacity and difference of glued and unglued cocoon layers can be reduced, and the phenomenon that sericin is excessively dissolved and lost due to the fact that a large amount of water is absorbed by unglued areas is avoided.
The invention provides a cocoon cooking method for silkworm cocoons, which has the advantages of less sericin loss and small reeling fold, can ensure the subsequent reeling process to be smoothly carried out, and improves the utilization rate of the silkworm cocoons.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
