The invention relates to agriculture, livestock, such as sheep, namely the allocation of wool fat, lanolin from the wool of sheep.
In the composition of the grease washed from sheep's wool contains wool fat, which is the product of secretion of sheep. Purified wool fat called lanolin.
The chemical composition of lanolin is complex, depends on the breed of sheep and conditions of their cultivation, method of producing wool fat.
Known methods for producing lanolin provide for the washing of wool with the use of aqueous solutions of surface-active substances. The formation of waste water, in which wool grease and organic impurities of grease are in the form of an emulsion stabilized by surface-active substance used for washing wool. Subsequent extraction of wool fat from such wastewater organic solvents it is clogged as organic impurities of wool grease, and surface-active substances used for cleaning. This fat for lanolin should be subjected to intensive cleaning, which is associated with additional costs and loss of product (patent Switzerland No. 507183, 1972).
A known method of extraction of lanolin from the wool fat, including deodorization, bleaching of wool grease and oxidation of impurities by b is botirovna air through the molten fat (RF patent No. 1833412, BI No. 29, 1993).
Also known is a method of obtaining wool fat, including sequential irrigation fur of a polar and non-polar solvents sequential irrigation in the direction of increasing their hydrophobicity (RF patent No. 2083647).
It is known that the composition of the grease washed from sheep's wool contains wool fat, which is the raw material for the production of lanolin, and surface-active organic compounds, resulting in high emulsifying ability of the grease. Wool fat has a very small polarity (ε=1,9-2,3). Therefore, it is highly soluble in non-polar, is not miscible with water, solvents such as hydrocarbon, with a low dielectric constant.
Related fat organic substances contained in the complex "suint"are devilry character, i.e. dissolve well in polar solvents with a high dielectric constant, and non-polar - low dielectric constant.
The application for processing wool polar solvents leads to a tone that dissolves the whole complex of suint, i.e. fat and associated organic matter.
Lanolin, derived in the process of refining wool grease, must meet the stringent requirements of the medical and cosmetic industry.
The presence of SOS the Ave of grease, surface-active substances and their transition into miscella wool fat results in the refining process to the formation of complex emulsifiers, which complicate the process, reducing its hydrodynamic conditions and creating on the border of the reacting phases of the intermediate layer. Due to this blockage of the finished product impurities intermediate layer, and due to the emulsification increased loss of lanolin with neutralizing solution. Components of the intermediate layer, getting in lanolin, increase its melting point and give it a dark color. To obtain lanolin light tones with indices satisfying the requirements of farmacopea, miscella wool fat containing impurities intermediate fractions, requires more intensive treatment that involves additional cost and reduces yield.
The disadvantage of all known methods is that they do not provide high-quality wool fat and that the solvents are removed from the hair the whole complex of suint, i.e. fat and associated organic matter defiling nature, which degrades the quality of fat and hinders its further processing in order to obtain lanolin.
There is also known a method of extraction of wool grease from the wool of sheep, namely, that the wool taken from sheep, washed with a special detergent solution, and then using the separating method or flotation retrieves sherstkyi-lanolin (Primary processing of wool. M., "Light industry", 1981, pp.272-281).
The disadvantage of this method is the high consumption of water, detergents and energy, loss of quality lanolin because of its pollution and exposure to chemicals.
In the process of conducting a patent search was not detected inventions that could be taken over the analogue and the prototype of the invention.
Extraction of fat directly from your hair cleaning solutions and oxidants provides a cleaner product and technologically easier.
The task of the invention is the extraction of wool fat, namely, lanolin, through the use of mechanical and thermal effects on the fleece taken from sheep.
In use of the present invention there is an opportunity to highlight wool fat, lanolin from the wool of sheep without pollutants and without the use of complex impact of cleaning chemical compounds on wool fat, lanolin and to pass to the factory primary processing more pure wool, which will increase its price.
The above technical result is achieved in that in the method of obtaining wool fat, lanolin, including removing the wool grease from the wool taken from the animal's coat - fleece fix on a special coil base fibers to the outside, is placed inside the mouth of ovci, which serves the air, heated to 90°and rotating the coil with a fleece with a speed of 900 rpm, creating a centrifugal force, through which the heated particles of fat fly with wool fibers and are placed on the inner surface of the casing installation, and then accumulated on the inner wall of the casing installation wool fat, lanolin harvested by scraping or Oceania.
The speed of rotation provides the centrifugal force, which is not exceeded acceptable seal coat ≈ 500 kg/m3.
The result is that for implementing the method proposed device containing a rotating coil with the axis of rotation that is installed in the housing unit for adsorption is carried wool fat, lanolin, drain tube, actuator for rotation of the coil, a source of heated air (e.g., heater)providing heated fleece coat.
The drawing shows a General diagram of a device for the extraction of lanolin from the wool of sheep.
The extraction device wool fat includes a housing 1, a rotating coil 2 with fleece 3, the discharge tube 4, the actuator 5 for rotation of the coil 2 and the source of heated air 6.
Removing the wool fat, lanolin is as follows.
Captured using a cutting machine with sheep fleece is fixed on the coil 2 so that the base of the ox is con wool (fleece) 3 were directed from the axis of the coil 2 to the outside. Then put the coil 2 with wool inside the chamber 1, is combined with drive shaft 5. The coil 2 source of heated air 6 delivers heated to a temperature of 90°the air enters the actuator 5, and the reel 2 rotates at a speed of 900 rpm, the particle wool fat, lanolin under the action of centrifugal acceleration deposited on the wall of the body 1, where the accumulation of wool fat, lanolin scraped or drained through the drain pipe 4.
The study of the proposed method of allocation wool fat, lanolin were obtained from the experimental data, which showed that the frequency of rotation of the coil 2 is set to 900 rpm, the temperature of the air supplied to highlight wool fat - up to 90°C. These parameters depends on the duration of grooming, retention fleece, ambient temperature, saturation of grease in the fleece and extent of contamination rune.
A specific example of performing the method of obtaining wool fat, lanolin from the wool of sheep
Captured with animal fleece is fixed on the coil with the axis of rotation of the base fibers out and placed inside the chamber. Inside the chamber to deliver air, heated to 90°C.
