Its apparatus is composed of the container with exploding membrane on the cover and drier.
Description
Technical field
The sericin removal method and the equipment thereof of a kind of silkworm cocoon of the present invention, belong to silkworm cocoon under the high-temperature water vapor effect of certain pressure, the step-down suddenly after the breakaway of silk surface of its silk gum makes silkworm cocoon become the expanded silk flosssilk wadding that breaks away from silk gum, a kind of method that silk gum and expanded silk flosssilk wadding are separated again; This method mainly is to carry out in closed container.
Background technology
The known method that silk gum in the silkworm cocoon is separated with silk is that silkworm cocoon is put into the hot water immersion that contains sodium carbonate and NaOH and stirred certain hour, and silk gum is dissolved in the above-mentioned solution, pulls silk out and, dewaters and drying the formation silk flosssilk wadding through cleaning.The shortcoming of this method is: because silk gum is difficult to separate from the aqueous solution that contains sodium carbonate and NaOH, as separating, its expense is very high, most of producer drains it, and this waste liquid environmental pollution that contains silk gum is very serious, therefore, government pays close attention to and is limited this process very much; And silk gum is a kind of globulin, is the base stock that is worth very high serine; Another shortcoming of this process is, prepared silk flosssilk wadding bulkiness is poor, and the silk flosssilk wadding goods of producing with its not only do not have bulk performance, and is difficult to recover after compacting.
Summary of the invention
The sericin removal method that the objective of the invention is to overcome the shortcoming of above-mentioned prior art and a kind of silkworm cocoon is provided, the bulk performance of the silk flosssilk wadding that makes in this way is good; Regain the very high silk gum of practical value easily, avoid pollution simultaneously to a great extent environment.Another object of the present invention is to provide a kind of equipment of implementing said method, makes the program of implementing in the said method process simple, and the device therefor kind is few.
Purpose of the present invention can realize by following measure: a kind of sericin removal method of silkworm cocoon, it is characterized in that making silkworm cocoon also expanded by the rotating closed container sericin removal that rupture disk is housed, its condition is: the saturated vapor pressure in the closed container is 0.4-0.6Mpa; Closed container rotated 8-12 minute with 5-10 rev/min; Rupture disk broke when the pressure in the closed container rose to 0.75-0.8MPa; The expanded silk flosssilk wadding that contains silk gum makes silk gum separate with expanded silk flosssilk wadding with a certain amount of water by the rotating closed container that rupture disk is housed, its condition is: the saturated vapor pressure in the closed container is 0.2-0.4Mpa, closed container rotated 8-12 minute with 5-10 rev/min, will contain the expanded silk flosssilk wadding dehydration of the silk gum aqueous solution; Expanded silk flosssilk wadding dredged wash, and dehydration, drying; The aqueous solution that will contain silk gum filters, concentrates, dry.
The employed equipment of sericin removal method of the above-mentioned silkworm cocoon of the invention process, comprise and dredge cleaning device and dewater unit, it is characterized in that rotating closed container in addition, which is provided with the explosion flap of band rupture disk and two semiaxis that are bearing in the symmetric arrangement on the bearing block, one of them semiaxis passes through sprocket wheel, motor on chain and the frame links, and the intermediate throughholes of another semiaxis communicates with the closed container inner chamber by swivel joint.
The inventive method compared with prior art has following advantage: because the coefficient of expansion of silk in the silkworm cocoon and silk gum is different, and at high temperature, mutual collision between higher pressure and the silkworm cocoon reduces the affinity between silk gum and the silk greatly, and facilitates silk gum breakaway on silk; Suddenly reduce to zero after its pressure rises to 0.75-0.8Mpa, the volume of silk increases suddenly, causes silk gum and silk to break away from fully; The silk flosssilk wadding after expanding and mixture and a certain proportion of hydration of silk gum are in the same place, and the result who operates under the high temperature elevated pressures and the condition of colliding has mutually quickened the dissolution velocity of silk gum in water once more, impels separating fast of silk gum and silk flosssilk wadding.Can extract with the inventive method and to account for silkworm cocoon 15---18% silk gum, this is to be worth very high product, is the base stock of making serine; Do not add any chemical substance owing to the inventive method again, so do not produce the discarded object of any contaminated environment in all processes of the inventive method, therefore second advantage comparing with known method is to have avoided environmental pollution; The 3rd advantage is by in a flash expanded at silkworm cocoon, since the unexpected expansion of silk volume silk vertically on produce many cracks as shown in Figures 2 and 3, therefore increased the volume under the silk flosssilk wadding nature, because the air that holds in its volume increases, the silk flosssilk wadding that therefore also shows after expanded is soft and flexible again.
Implementing device therefor of the present invention compared with prior art has following advantage, and device therefor is simple in structure, and device category is few.From abovementioned technology as seen, its silkworm cocoon come unstuck and expanded capital equipment be an explosion flap that the band rupture disk is housed can rotating closed container, and this closed container can finish the sericin removal and the expanded operation of silk, can finish the separation circuit of silk and silk gum again.
Description of drawings
The accompanying drawing drawing is described as follows:
