Abstract
The invention discloses a pretreatment method for fresh cocoons, comprising the following steps: the fresh cocoons purchased from a cocoon station are fed into a conveyer belt before moths flying out; the conveyer belt brings the cocoons to the temperature of minus 2-minus 4 DEG C; after 0.15-0.75 hour, the cocoons are brought to the temperature of minus 5-minus 18 DEG C by the conveyer belt; after 2-48 hours, the cocoons are brought to the temperature of 0-4 DEG C by the conveyer belt; after 0.15-0.75 hour, the cocoons are brought to the normal temperature by the conveyer belt for 2-30 hours of natural balance; and then normal hot air drying or superheated steam drying is carried out. The invention adopts a dynamic freeze pretreatment and the pretreatment can be carried out continuously; after the fresh cocoons are pretreated, silkworm pupa can be killed, limited cocoon drying time can be relieved, in particular, the reliability percentage is enhanced, and the rushing-upon frequency per 10000m can be reduced; and damage of inner cocoon layers caused by the fact that immature cocoons are activated by heating in the cocoon drying process can be reduced.
Description
Technical field
The present invention relates to the cocoon drying pretreatment technology, especially relate to a kind of preprocess method of bright cocoon.
Background technology
Though China is maximum in the world production of silk silk fabric and exported country, cocoon yield accounts for more than 75% of world production amount, and in fact China has that silk cocoon more than 30% is poor because of reelability percentage, myriametre is hung rough height and can not be used for filature.On the other hand, the filature enterprise of China particularly the filature enterprise ubiquity of east the problem of raw material cocoon deficiency.Therefore, if by suitable technology, the reelability percentage of raising silk cocoon, reduction myriametre are hung rough, not only can alleviate the gap problem of raw material cocoon, and for improving raw silk quality important effect are arranged also.At present, in order to improve the silkworm cocoon reelability rate, some local employing fresh cocoon reelings are arranged, but the shelf-life of bright cocoon is very short, is unfavorable for long-term filature; Also have by after the long-term freezing processing,, directly carry out filature, but need big freezer without cocoon drying.In addition, also can't reduce myriametre and hang rough number of times.
Summary of the invention
Low in order to overcome the reelability percentage that has silk cocoon now, myriametre is hung the high problem of rough number of times.The object of the present invention is to provide the pretreated method of a kind of bright cocoon, kill silkworm chrysalis, improve the silkworm cocoon reelability rate, reduce the silk cocoon myriametre and hang rough by bright cocoon being carried out the dynamic freezing preliminary treatment of short time, reaching.
The technical solution adopted for the present invention to solve the technical problems is that the step of this method is as follows:
1) the bright cocoon that the cocoon station is purchased, before not going out moth, after changing over to it in conveyer belt, by conveyer belt bright cocoon is brought in-2 ℃～-4 ℃ the environment temperature, 0.15 after～0.75 hour, enter by conveyer belt in-5 ℃～-18 ℃ the environment temperature, after handling in 2～48 hours, utilize conveyer belt silk cocoon to be brought in 0～4 ℃ the environment temperature, 0.15 after～0.75 hour, utilize conveyer belt to bring silk cocoon into normal temperature, after 2～30 hours natural equilibrium, enter normal heated-air drying or superheat steam drying technology.
2) in this aquatic foods cocoon preprocessing process, silk cocoon is in the dynamic process, is the bright cocoon preprocess method of continous mode.
That is to say that the present invention is bright cocoon by after low temperature-more low temperature-normal temperature is handled, and carries out normal drying.
Because bright cocoon contains large quantity of moisture, through after freezing, water build-ups ice, and it is big that volume becomes, reduced the deadlocked power between silk, particularly internal layer cocoon layer, because of its moisture content is big, decrease will be more obvious, thereby the internal layer thread that falls is reduced, thereby improve reelability percentage, reduce myriametre and hang rough.
The beneficial effect that the present invention has is:
1) utilizes dynamic freezing pretreatment technology, bright cocoon pre-treatment can be finished at short notice, and preliminary treatment can be carried out continuously.
2) after bright cocoon carries out preliminary treatment, except killing silkworm chrysalis.Outside the problem that the alleviation cocoon drying is pressed for time, especially also have the raising reelability percentage, reduce the silk cocoon myriametre and hang rough effect.
3) can reduce in the cocoon drying process, immature cocoon is destroyed the internal layer cocoon layer because of heating makes its movable aggravation.
