Description
Technical field
The invention belongs to the cocoon cooking technical field of Bombyx bombycis, be specifically related to the cocoon cooking process under a kind of high altitude environment.
Background technology
Silkworm district is originated at height, especially in Yunnan Province, the main producing region of Bombyx bombycis and filature main production area sea level on the average are between 1800～2200 meters, affected by Plateau Characteristic weather, fall behind sericulture technology restriction, Bombyx bombycis index has following deficiency compared with other provinces: gum content is on the low side, cleaning, cleaning the poorest, class is hung higher, is difficult to produce high-grade raw silk.
Summary of the invention
It is an object of the invention to provide the cocoon cooking process under a kind of high altitude environment, he can preferably solve, and high to originate in the Bombyx bombycis gum content that silkworm district exists on the low side, and cleaning, cleaning are the poorest, and class is hung higher, is difficult to produce high-grade raw silk,
The appropriate technical solution taked of technical problem solving the present invention is: cocoon cooking process is mainly made up of the operations such as cocoon, cocoon cooking, filature of selecting silkworm, steam, when 1. selecting silkworm, control the ratio of soup cocoon less than ten thousand/；When 2. steaming cocoon, when Cocoon layer ratio is at 48%～49%, steam cocoon pressure 0.06 ± 0.01MPa, when Cocoon layer ratio is higher than 49%, steam cocoon pressure 0.08 ± 0.01MPa, when Cocoon layer ratio is less than 48%, steam cocoon pressure 0.04MPa ± 0.01；3. during cocoon cooking, infiltration water temperature controls at 30 ± 5 DEG C, auxiliary agent uses aliphatic ester derivatives, surfactant and the silk impregnating agent of mineral oil mixture composition, cocoon cooking is joined temperature and is comprehensively rested in: Suo Lixu efficiency ＞ 70%, reelability percentage ＞ 50%, running rate ＞ 90%, sericin degumming loss percentage is 4～5%；4., during filature, beating soup temperature is 88 ± 2 DEG C.
The described steaming time 60～90 minutes when steaming cocoon, vexed cocoon time 9～11 minutes.
Silk impregnating agent used by cocoon cooking is the EKL 101 universal silk impregnating agent of longitude and latitude that Hangzhou quintessence Chemical Co., Ltd. produces, and adds cocoon weight 2.2～the glacial acetic acid of 2.5% in the export department of cocoon cooking machine.
The method have the benefit that: by the process above optimization of the present invention, Bombyx bombycis raw silk product all can reach class 5 A, 6A, meets the peak demand of industry quality standard, thoroughly solves the problem that the high altitude localitiess such as Yunnan can not produce high-grade raw silk；And the raw silk product using tradition cocoons-boiling method to obtain, can only achieve grade 3A under optimum.
