The invention relates to the light industry and may be used in the processing feather down raw materials.

Feather down the mixture, which is used as filler, such as pillows, necessary to treat for disinfection and destruction of smell. Technological process of processing feather down raw material depends on the type of raw material.

On feather down factories for cleaning feather down raw materials are imported or domestic washing substances, as well as for pre-treatment use ozone is a strong oxidant that helps stop the activity of complex organic matters of protein nature.

There is a method chamber disinfection with ozone, in accordance with which things are placed in a sealed chamber, fill the chamber with ozone, circulate ozone-air mixture, after disinfection are degassing chamber, things being unloaded while disinfected things stand in the chamber with ozone concentration of 2 g/m from two to six hours at boot camera 10 m 3 from 40 to 120 kg (see RF patent №2279897 "Method chamber disinfection with ozone", IPC A61L 2/20, publ. 20.07.2006 year).

The disadvantage of this method is the insufficient quality of the final product.

Also known way of handling feather down raw materials (see RF patent №2446830 "Way of handling feather down raw materials", IPC A61L 9/15, D01B 3/00, publ. 10.04.2012), which feather down raw material is placed in a sealed chamber, fill the chamber with ozone, after ozonation spend ventilation chambers, feather down raw materials unloading. Raw materials in a sealed chamber is placed in a vertical position on a stationary racks located at height of 45 cm from the floor level, ozone generators have at the entrance and exit the camera at a height of 2,5 m from the floor level, the ozonation process takes place at a temperature 15-35 C, air humidity from 45 to 80% and ozone concentration in the chamber of 5.8 mg/l for 60 min at boot camera raw material weighing from 3500 up to 7200 kg After the process of ozonization of outdoor exercise of supply and exhaust ventilation for 60 minutes, after which produce pre-dedusting of raw materials, primary sorting, washing with detergents at the temperature of the water 42 degrees C, followed by multiple rinsing, pressing, coating raw materials wax, drying, cooling, final dust removal and sorting.

The disadvantage of this method is also insufficient quality of the final materials.

A prototype of the invention taken processing method feather down the raw material used at the enterprise "Seraphim factory of feather down products" (see http : //www.spo007.ru), consisting in 2-fold repetition of the process of washing raw materials with use of the certain temperature water with addition of powders on the base of surface-active substances (SAS).

The disadvantages of this method are the insufficient quality of the final product, high consumption of spent resources.

The technical result of the invention is to increase the quality of the final product, the increase in output feather down semi-finished product, saving resources.

To do this before washing is pre soaking raw materials, washing of raw materials includes two washing for 10 minutes at a water temperature 35-42 degrees Celsius in the dependence on raw materials with intermediate rinsing, rinsing after washing is carried out in 6 cycles 6 minutes in a large volume of water, the first rinsing water temperature 30-35 C, subsequent to 7 C, after the two last rinse water enters the recirculation tank for later soaking raw materials, in the penultimate rinse raw materials processed vocoderion drug, drying pure raw materials is carried out at a temperature of 120 degrees C for 30 minutes at pressure 2 bar, then dried raw material is cooled and dust should be removed from within 10 minutes

This improves the quality of the final product and to increase the proportion of output, to save electricity.

Below is a schematic representation of the cleaning process feather down raw materials.

The stated method of processing feather down raw materials is as follows. Pre happens soaking feather down raw materials, water is taken from the recirculating tank in which it is supplied from two last rinse. Washing of raw materials includes two washing for 10 minutes at a water temperature 35-42°C depending on the type of raw materials to intermediate rinsing. Washing is done with the addition of 1 kg of raw 3.5 g detergent production Pulcra Germany - Foryl FKN. After washing raw material is subjected to repeated rinsing (6 cycles 6 minutes) in a large volume of water. When you first rinse water temperature 30-35 C°, further - 7 degrees C. After the two last rinse water enters the recirculation tank for later soaking raw materials. In the penultimate rinse raw materials processed vocoderion drug Nicwax (for 1 kg of raw materials - 1 g "wax"). After rinsing the raw material is released. The humidity of the raw material after wringing is 40%. Wet pure raw materials is supplied by pipeline to the bunker drive and a portion goes into the drying chamber. Drying takes place at a temperature of 120 degrees C for 30 minutes at pressure 2 bar. All the water used in washing feather down raw material is discharged through vibrating screens. Dried raw material is fed into the drum for cooling and dust proof. The process lasts for 10 minutes, resulting sorted pile. Chilled raw materials are unloaded in net bags.

The results of the tests are presented in tables 1-3, prove the feasibility pre-soaking. It allows to prepare the raw materials to the supply of detergents, reduce surface tension and thus more economical use of consumables, namely to reduce the use of detergents with 4 g to 3.5 g on 1 kg of raw materials, and reduce energy consumption for heating water to rinse (2-6 cycles).

Plum of water last two rinse come to the recirculation tank. Water is re-used for further soaking subsequent batches of raw materials. The temperature of water after the last two rinse is 10-15 C, which allows to avoid additional heating water for soaking and to save electricity. Water recirculation tank is used on homogeneous raw materials, changing raw materials only in accordance with established procedure: "goose-duck-chicken". Energy conservation, waste minimization and saving water and detergents are mutually supportive elements of the technology.

In the penultimate rinse raw materials processed vocoderion drug Nicwax (for 1 kg of raw materials - 1 g "wax"), which reproduces the effect of secret, secreted by a gland birds. This allows to keep the natural stylus properties (thermal conductivity, elasticity, water-repellent properties), prevents the growth of microorganisms.

Table 8 presents data according to the index of elasticity 8 feather down semi-finished FP from the use of the drug Nicwax.

The survey results in table 8 show the feasibility of refining of raw materials vocoderion drug Nicwax, which improves elasticity feather down semi - one of the most important indicators of quality.

After all rinse cycles raw material is released. The humidity of the raw material after wringing is 40%. Wet pure raw materials is supplied by pipeline to the storage hopper and a portion goes into the drying chamber. Drying in the drying chamber is made at a temperature of 120 degrees C for 30 minutes at pressure 2 bar.

All the water used in washing feather down raw material is discharged through vibrating screens. The advantage of this setup is applied on a purely mechanical principles of water treatment without use of chemical reagents. A multi-stage water purification using shale shakers allows to filter out the feather and feather down the pile that is environmentally friendly use of this technology. Filtered on the shale shakers feather and feather down the pile are recycling, which can significantly reduce waste and increase the output feather down semi-finished up to 100%.

Dried raw material is fed into the drum for cooling and dust proof. The process lasts for 10 minutes, resulting sorted pile. Cooled to a temperature of 18-20 degree Celsius C raw materials are unloaded in net bags.

The result of this technology of deep industrial processing is perfectly clean feather down raw materials with permissible humidity 10% to 12%, which corresponds to the requirements of GOST P 30332-95. Products feather down. General specifications.

This sequence of industrial processing feather down raw materials allows to increase the quality of the final product due to the fact that completely eliminate residual detergent, pollution, microbial semination, as evidenced by the value of the oxygen index, completely removed smell, are naturally stylus properties (thermal conductivity, elasticity, water-repellent properties), provided hypoallergenic materials. Sterility of raw materials is achieved by a set of optimal parameters of processing: water temperature and the number of rinses, the concentration of detergents, carrying out of finishing materials vocoderion drug Nicwax.

This method is also environmentally friendly, as it does not use such chemicals like formaldehyde and chloramine, saves resources spent. How accessible and easy to use.

Method for processing feather down raw material is two-fold repetition of the process of washing raw materials, subsequent rinsing, processing vocoderion product, the pressing and drying, differs in that the pre is soaking raw materials, washing of raw materials includes two washing for 10 minutes at a water temperature 35-42 degrees Celsius in the dependence on raw materials with intermediate rinsing, rinsing after washing is carried out in 6 cycles 6 minutes in a large volume of water, the first rinsing water temperature 30-35 C, when the next 7 C, in the penultimate rinse raw materials processed vocoderion drug, after the two last rinse water enters the recirculation tank for later soaking, drying pure raw materials is carried out at the temperature of 120 C for 30 minutes at pressure 2 bar, then dried raw material is cooled and dust should be removed from for 10 minutes, all used in the processing of water is diverted through the shale shakers.
