Problems solved by technology

The disadvantage of this method is: because sericin is difficult to separate from the aqueous solution containing sodium carbonate and sodium hydroxide, if it is to be separated, the cost is very high, most producers will discharge it, and this silk-containing The waste liquid of glue pollutes the environment very seriously, so the government pays close attention to and restricts this process method; and sericin is a kind of globulin, which is the basic raw material of serine with high value; another of this process method The disadvantage is that the prepared silk cotton has poor bulkiness, and the silk cotton products produced by it not only have no bulkiness, but also are difficult to restore after compaction.

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with embodiment (accompanying drawing):

[0014] see figure 1 and Figure 4 , open the blasting hole cover 3 on the airtight container 4, put 2.5 kg of silkworm cocoon shells into the airtight container, close the blasting door, and send air to the airtight container through the steam pipeline and the rotary joint installed on one of the hollow rotating half shafts of the airtight container. The inner cavity delivers 0.4-0.6MPa saturated water vapor and maintains the above pressure. Start the motor 10 that is fixed on the frame 9, then by the chain 8, the sprocket wheel 7 that is respectively contained on the other semi-axis of the airtight container and the sprocket wheel 7 on the motor makes the airtight container rotate 8-12 at a speed of 5-10 revolutions per minute. Minutes, the cocoon shells are subjected to high temperature and high pressure water vapor in the airtight container and ...

Abstract

A process for removing sericin from silkworm cocoons includes such steps as adding silkworm cocoons into a rotary container, sealing the container, high-temp. and high-pressure treating for a certain, time to strip sericin from silk, suddenly releasing pressure to make the cocoon become puffed silk floss separated from silk and sericin, separating sericin from silk, and dewatering each of them. Its apparatus is composed of the container with exploding membrane on the cover and drier.

Description

technical field [0001] The invention discloses a silkworm cocoon shell desericin method and its equipment, which belong to the silkworm cocoon shell under the action of high-temperature water vapor at a certain pressure, and the sericin is peeled off from the silk surface and then the pressure is suddenly lowered so that the silkworm cocoon shell becomes detached from the sericin Expanded silk cotton, and then a method of separating sericin from expanded silk cotton; this method is mainly carried out in a closed container. Background technique [0002] The known method of separating the sericin in the cocoon shell from the silk is to soak the cocoon shell in hot water containing sodium carbonate and sodium hydroxide and stir for a certain period of time to dissolve the sericin into the above solution, remove the silk and After washing, dehydration and drying, silk wool is formed. The disadvantage of this method is: because sericin is difficult to separa...
