Abstract

The invention relates to the production of gelatin alebs gleja, najma gelatine for food industry or for photographic production eaulzii. The purpose of the invention is to utilize waste large capacity carcass lines industry - treadmill - for growth source of quality raw material for extraction gelatin and glue, at lower need chemical agents, energy and technology science for production and simplified ·· production technology *. This purpose is glejevlas, ktevú doors crushed by hydropods, harvests blood · iaýsh emptied by the other “participation, macerated” in the environment, it will be liming.

Description

The object of the invention is a glue, a collagen material adapted for the production of gelatin and glue.

Hitherto used collagen materials for the production of gelatin and glue, such as glue and esein, predominantly and bones and bones hevddzlehe cattle and pigs. Teehnelegleký peatup carving of the material for the production of gelatine and glue and tyohte raw material is quite tedious and laborious. The pre-prepared keat and the skins and during the digestion must be limed with a calcium hydrexide slice for 5 to 14 weeks. Separate teohneleglokeu eperaceu in the production of klaganeal material from the keati is a rather peat peatup extraction · fat pemeoeu resolves or leaks of steam · The raw material and the baking of the cuts must sweep through the science a lot for the purpose of leaching, respectively. washout unwanted ebaahev. The production of collagen material and waste is characterized by a high consumption of water, calcium hydrexide or other chemical agents and a large range of calcium and other undesirable waste wastes. The disposal of wastewater requires large quantities of chemicals for neutrallzal.

For continuous production, it is usually necessary to store up to three times the raw material and the ternum corresponding to the extensive storage and handling of the heaters and equipment. A considerable number of technological epereas in the production has an adverse effect on the quality of the material from the used raw materials and its price is relatively high.

The above-mentioned drawbacks are substantially eliminated by the sizing according to the invention, characterized in that it consists of crushed feet of poultry, free of blood and other extractable components, macerated in an acidic environment, e.g. in a 2 to 4% hydrochloric acid solution; also lime, e.g. 1 to 3% calcium hydrexide solution.

The size of poultry footwear is relatively laone and quicker than the raw materials used so far. Its production is faster and less prone. No need to extract fat from the feet. It is not necessary to calcify the raw material during the production. A substantial portion of the physico-chemical pre-sieves are faster and more efficient in production. By eliminating the need for the above mentioned technological epereas, the number of necessary washings has also been reduced, thus reducing the water consumption by 10 to 50 liters. The production requires less chemical boats. The volume of waste water and the treatment and cleaning costs will be reduced. The specific energy consumption will be reduced for the preparation of the raw material for the production and for the self-production of the collagen material. The production of glaze from poultry feet can be mechanized and automated. aj kentinualizovat. It will allow the highly efficient utilization of edpade raw material from large-scale lines for slaughtering poultry, previously used for the production of micro-bone meal or for direct feed. The gelatin of poultry feet and thus the gelatin produced therefrom have, on average, a relatively higher and more uniform quality than that produced under the same conditions from the raw materials used hitherto.

The Gisjsvine according to the invention can be produced, for example, as follows:

Example 1.

The feet are continuously crushed in a shredder located below the suspension conveyor of the poultry processing line at the point of unhooking from the stirrups of the suspension conveyor and automatically transported by a pneumatic conveyor to the storage tank. The crushed feet are washed 5 times with clean water at a weight ratio of feet: 1: 3, so as to shed blood and other washable undesirable admixtures. After washing, a and maoerize in an acidic environment, preferably e.g. 2-4% diluted hydrochloric acid for about 6 to 10 hours, at a ratio of 1: 2 foot to maceration reagent, until complete demineralization of the bones. Then the macerating agent is pumped off and its residues washed away by washing with pure water in a ratio of feet: water 1: 3, a total of 3 to 4 times or continuously to 3.0 to 4.0 pH of the feedstock.

Glue for the production of high-quality photographic gelatine can be produced, for example, as follows:

Example 2.

Proceed as aa as in example 1, except that after washing with pure water to 3.0 to 3.0

The pH of the glue is lime, preferably 1 to 3 with a calcium hydroxide solution for 5 to 15 days, then washed with clean water and acidified, preferably with dilute hydrochloric acid to 3.0 to 4.0 pH, and finally freed by rinsing with diet water with salt and acid residues up to 4.5 to 6.0 pH.

Claims (1)

OBJECT OF THE INVENTION An oil characterized in that it consists of crushed feet of poultry, free of blood and other washable components, macerated in an acidic medium, in a 2 to 4% solution of hydrogen chloride, possibly also lime, with a 1 to 3% solution of calcium hydroxide.
