Straw
Straw - dry stems of plants, as a rule, exempt from the leaves, flowers and seeds. Straw for transportation, storage and further use is pressed by special machines in rolls or bales. By sustenance it’s considerably inferior to the hay. Straw contains almost no vitamins, she poor proteins (2 - 4%), fats (1 - 2%) mineral salts. Only indigestible fiber (32 - 40%) is many in the straw, which significantly reduces the value of straw as fodder culture. Therefore, the straw is almost a waste of agricultural production (crop production). Since in the production of one ton of grain is formed from 1.5 tons (barley) to 2.4 tons (corn) straw, the total quantity of waste in the straw form in the country becomes huge. So in the south regions of Russia: Krasnodar territory, the Rostov region annually are produce up to 3 million tons of unclaimed straw. As a rule, it disposed directly in the field (in the best case are incorporated, in the worst - burn). Straw has a lot of use cases, however, it is of interest to us as a fuel. Straw usually has a relatively low relative moisture (usually - not more than 25%) and a high combustion heat: wheat straw - 17 ... 18 MG/kg, rape straw - 16 ... 17 MG/kg, corn - about 18 MG/kg. However, straw has a relatively low density, so its transportation over large distances can be profitable only in pressed form. Fortunately, straw is well granulated and briquetted well. In pressed form it can be submitted in boilers automatic systems, therefore, is a high-quality and convenient local fuel with a relatively low price. For this reason, straw using as a raw material for the production of fuel pellets and briquettes is profitable and promising business.
But straw use isn't limited to it. Use of the Unit of drying-crushing of series АS-4 at straw processing in granules (pellets) leads to almost full sterilization of straw. Besides, absorbing properties of straw considerably increase in such kind. If to use such granules as a laying at cultivation of young growth of a bird, risks of diseases of baby birds essentially decrease, death rate decreases. Hence, profitableness of business increases. The given properties of the straw granules received with use of Unit AS-4, do by their best kind of a laying at cultivation of young growth of a bird.
We already make the equipment of two factories on manufacture of granules of straw. The first is in Vodjanoye of the Shpoljansky region Cherkassk area of Ukraine (more in detail), the second – in v. Borodichi of the Zelvensky region Grodno area of Belarus.
On page "Video" it is possible to watch a film about manufacture of granules from straw on the equipment made by us.
