Abstract
The invention relates to a preservation method for a precious raw hide, which includes the steps of scraping oil on the raw hide after butchering, drying the raw hide, filling the raw hide into a multi-layer coextruded film vacuum bag, welding a one-way extraction valve made of PE (polyethylene) materials on the vacuum bag, vacuumizing the vacuum bag with a vacuum pump so that the vacuum degree reaches -80Kpa, and performing normal-temperature preservation in dark place, wherein the width of the vacuum bag is 40cm, and the length of the vacuum bag is 10-20cm longer than that of the raw hide. The method is capable of preserving the precious raw hide for half a year without obvious change on quality of the raw hide. The method has the advantages of simple equipment, low cost, reusability of the vacuum bag, no energy consumption and no pollution, and is worth of popularization and application.
Description
Technical field
The present invention is the preservation of a kind of method for preserving of rawhide, particularly precious rawhide.
Background technology
There is not the fur of tanning to be commonly called as rawhide; Rawhide is easy to go bad because of containing a large amount of greases and albumen, can not long preservation, and particularly precious rawhide such as fur, fox skin etc.; Economic value is higher; Rawhide after butchering such as untimely tanning be easy to cause depilation, tarnish even problem such as rot, thereby the economic value of rawhide is reduced even lose, and causes economic loss.
Rawhide is only our operable fur through after the tanning, is commonly called as bark.The tannery of fur and tanning quality are very big to the price influence of bark.The tanning of rawhide is technology and all very strong technology of technical requirements; The tanning of precious rawhide is many to be born by external major company; Domestic general plant does not possess the technology and the condition of the precious rawhide of tanning, they just will pass through simply dealt rawhide directly sell can the tanning rawhide company.Often influence the quality of rawhide from slaughtering the rawhide sale, thereby influence the final price of rawhide because of overlong time.
Traditional rawhide storage method is with the rawhide frizing after butchering, dries back antiseptic preservation or freezing.Anti fouling composition can exert an influence to the gloss of rawhide during antiseptic preservation; The freezing power consumption is bigger, and long-time preservation also can influence the gloss of rawhide because of oxidation.
Summary of the invention
Purport of the present invention is the deficiency that overcomes prior art, and a kind of method of simple, the practical and effective precious rawhide of preservation is provided.
The present invention adopts PP TYPE as vacuum bag, and welding PE material list uses heat sealing machine to seal to extraction valve, the precious animal hides of the method for preserving preservation that vacuum pump vacuumizes.
PP TYPE is made up of resins such as PA, EVOH and PE, EVA, adopts symmetry or non-symmetrical unitized construction, the packing of the high grain of the most suitable oxygen barrier, protection against the tide and requirement of strength, food, chemical, medical product.
Of the present invention specifically is to realize according to following steps:
A: vacuum bag is selected the wide multi-layer co-extruded membrane material of 40cm for use, and PP TYPE is cut into the long tubular of length greater than rawhide length 10-20cm, and an end seals with heat sealing machine.
B: the unidirectional extraction valve of welding PE material in the vacuum bag appropriate location.
C: the rawhide of the appropriate amount of packing into, seal the other end with heat sealing machine.
D: use vacuum pump that it is vacuumized, degree of vacuum is reached-80KPa.
E: the PP TYPE vacuum bag can repeated usage, only need cut off fraction next time when using and seal and get final product.
The present invention and commercially available difference of taking in the collecting bag of clothing are that material has adopted PP TYPE and two ends all to adopt heat seal, rather than install and seal slide fastener, have so promptly reduced cost, have improved the reliability that guarantees degree of vacuum in the bag again; Be that with the vacuum-packed difference of using on the food PP TYPE vacuum bag can repeated use can grasp with the size of bag flexibly.
The present invention confirms through reality: a 40cm is wide, and the long vacuum bag of 1m can be placed 20 furs.Lucifuge normal temperature is preserved half a year under initial depression-80KPa, degree of vacuum decline 20KPa, no significant difference before rawhide quality and the preservation.Vacuum bag repeated use 7 times does not break, gas leak phenomenon.
Claims (5)
1. the method for preserving of precious rawhide before the tanning is characterized in that rawhide is carried out frizing, adopts the PP TYPE vacuum bag packages in the processing after drying, and unidirectional extraction valve is installed in the appropriate location, and vacuum pump vacuumizes preservation.
2. according to the method for claim 1, vacuum bag is selected multi-layer co-extruded membrane material for use.
3. according to the method for claim 2, the vacuum bag two ends all adopt heat sealing machine to seal.
4. according to the method for claim 1, weld the unidirectional extraction valve of PE material in the vacuum bag appropriate location.
5. according to the method for claim 1, use vacuum pump that it is vacuumized, degree of vacuum is reached-80KPa.
