Method of preserving the skins of sea animals

 

(57) Abstract:

The method refers to the fur industry and can be used in primary treatment of skins of sea animals for conservation in the process of harvesting the fields. Skins of sea animals subjected to poddelka vrastil, Tuzlukova in the capacity of compounds, including sodium chloride and antiseptic, with intermediate aging. As an antiseptic drug use "FG". Tuzlukova carried out in two stages, with antiseptic - drug "PF" in the first stage of Tuzlukova used in the form of 30-33% aqueous solution in the amount of 3-4 g/l After 24-36 h in the second stage of Tuzlukova add composition containing drugs "Gamma", "Eval" and isopropyl alcohol. For podsolka vrastil use of 1.5-2.0% aqueous solution at the flow rate of 100-120 ml on the skin containing the drug, "PF", and sodium chloride. The aging is carried out for 15-20 days. The technical result is to improve the quality of the preserved skins. 3 C.p. f-crystals, 2 tab.

The invention relates to the fur industry and can be used in primary treatment of skins of sea animals (marine mammals) in the process of harvesting the fields and prepare it for storage.

And apart Gamma - 3-5, the sodium chloride - 15-25, surfactant and 1.5 - 2.5. (RF patent N 2142512, MKI C 14 C 1/00, 1/02, bull. N 34, 10.12.99).

This method may not provide the required quality of preserving the skins of marine mammals during long-term storage and does not protect against the occurrence of various defects on the leather, including a blemish redness", because the method involves the processing of hides and skins of mink, which has a different structure of the leather and fur.

There is a method of preservation of fur raw materials by canning in a wooden or plastic barrels in an aqueous solution containing 1% sulfuric acid and 4-5% of sodium chloride, after which the barrel is closed and transported to a fur factory, where they are stored until processing of skins (Izyumov D. B., Radkevich D. P. improving the conservation of leather and fur and fur raw materials for meat processing plants. - An overview. - M.: Createimagedata, 1983, - 54 C.).

There is also known a method macromolecule preserving the skins of marine mammals by treatment with dry sodium chloride: straightened and laid vrastil skin fill a crystalline sodium chloride in the amount of 30-50% by weight of the skins. Placed in a pile on aging for 7-8 days. For unilinearity sodium, wrap (aging), stacking with additional application of dry sodium chloride. Canned 8 h (Belyakova Century. And. and other Technology furs and fur sheepskin. - M: Light and food industry, 1984, - S. 56-59).

Closest to the proposed method of primary processing of hides and skins of marine mammals to the technical essence and the achieved effect is a well-known method of preserving raw materials by Tuzlukova in the tank water, comprising (g/l): sodium chloride - 260, antiseptic (crematoria sodium) - 1-2 for 16-24 h at W 2.5 to 4 and a temperature of 10-20oC, Tuzlukova spend with reinforcement. Next, the raw material is unloaded and is aging 2 hours. Then spend Padalko dry sodium chloride.

To prevent macrosolen raw materials during long-term storage such vices as redness, salt spots, sodium chloride is added sodium carbonate, paradichlorbenzene, zinc chloride, hydrosulfite and sodium hydrosulphate, potassium phosphate, boric acid, naphthalene, potassium alum, kerosene (Fears And. P. and other Chemistry and technology of leather and fur. - M.: Legprombytizdat, 1985, - S. 27-30 - prototype).

It should be noted that Tuzlukova spend as subsequent poddelkoi and the known ways of preserving the skins of sea animals is the presence of conserved raw materials significant areas of the leather, plagued by the "redness" and "teclast hairline".

These defects adversely affect the quality of both raw materials and fur semi-finished product produced from this raw material. It is characterized by friability and low strength of the leather, teclast hairline.

The main problem to address with the inventive method of preserving the skins of sea animals, is to improve the quality of the skins after canning.

This object is achieved by the proposed method of preserving the skins of sea animals. The essence of the proposed method consists in the aggregate of the following essential characteristics sufficient to achieve the technical result: in the way of preserving the skins of sea animals by podsolka vrastil and Tuzlukova in the capacity of compounds, including sodium chloride and antiseptic with intermediate aging as an antiseptic, drug use "FG" on the basis of sodium formiate, Padalko vrastil conduct of 1.5-2.0% solution of the drug "PF" at the rate of 100-120 ml on the skin, Tuzlukova carried out in two stages - the first stage of the drug "PF" is used in the form of 30-33%aqueous solution of 3-tziklicheskih terpenes General formula C10H16O, "Eval" on the basis of anion active and non-ionic surfactants and isopropyl alcohol with the following content of components, g/l: drug Gamma 0.3 to 0.5, the drug "Eval" of 0.3-0.5, isopropyl alcohol of 0.5-0.7, the water to liters, and the aging is carried out for 15-20 days.

Considering the whole set of essential features, the inventive method of preserving the skins of marine mammals corresponds to the condition of novelty.

Comparative analysis of the proposed technical solutions to the prototype (see table. 1) shows that the proposed method differs from the known. These differences constitute the distinctive features of the proposed method: as an antiseptic drug use "FG" on the basis of sodium formiate, Padalko vrastil conduct of 1.5-2.0% solution of the drug "PF" at the rate of 100-120 ml on the skin, Tuzlukova carried out in two stages - the first stage of the drug "PF" is used in the form of 30-33% aqueous solution in the amount of 3-4 g/l, after 24-36 h in the second stage adds the composition containing the drug Gamma-based oxygen-containing cyclic terpenes General formula C10H16O, "Eval" on the basis of anion active and non-ionic surfactants and from saprophilous alcohol of 0.5-0.7, water to liters, and the aging is carried out for 15-20 days.

Drugs "PF", "Gamma", "Eval" issued by the industry on the basis of the technical conditions, respectively,

THE 238100-12/01-00302474-1998 "Drugs"Gamma",

THE 2484-173-05744685-99 "Eval".

The present invention may be found to comply with the condition of "inventive step", so as not detected known technical solutions that have the signs consistent with its hallmarks.

The mentioned set of features in comparison with the prototype achieves the claimed technical result.

The inventive method are optimal, since the output of the lower limit of the claimed technical result is not achieved, and the upper limit is economically disadvantageous.

Data supporting the achievement of the claimed technical result is shown in table. 2.

On standardized indicators skins fully comply with the requirements of GOST.

The processing of hides and skins of sea animals in accordance with the inventive method is as follows: after degreasing skins of sea animals skins applied by brush 1,5-2% aqueous solution of the drug, "PF" at the rate of 100-120 ml on the skin, and then sprinkled with chloride of sodium 500-600 g on the skin. At first the skin put the following botermans side up and the process is repeated. The skins are placed in a pile height of 1 m Then spend hides skins in the stack within 15-20 days. Next skins from a pile coiled Koshevoy cloth out and loaded into the container (wooden barrels), where they conduct Tuzlukova in two stages. In the first stage, the skins are treated within 24-36 h composition containing, g/l: drug, "PF" - 3-4, sodium chloride - 200-250, water (sea) to liters, and then in the second stage, add a composition containing, g/l: drug Gamma - 0.3 to 0.5, the drug "Eval" - 0.3 to 0.5, isopropyl alcohol - 0,5-0,7, water (sea) to liters. The barrel is closed and sent to the company.

Raw material is stored in barrels for up to 10 months at a temperature of 2-20oC.

Specific examples of the proposed method of preserving the skins of marine mammals are given in table. 1 (examples 1-3).

The proposed method of preserving the skins of marine mammals was tested under field conditions. The test results are positive.

The proposed method of preserving the skins of marine mammals can significantly improve the quality of the preserved skins:

- dramatically reduce crime kr is cunosti redness 3 times;

- reduce teclast hair 3 times.

Based on the above we can conclude: the proposed technical solution is new and meets the condition of "inventive step, because of the known prior art has identified effects distinctive essential features of the claimed result. The use of the proposed structure provides this technical result, which indicates compliance of this invention, the condition of "industrial applicability".
