In a world, constantly decreasing oil, coal and other fossil fuel reserves, people began to look for alternatives which could replace the fuel and reduce the rising fuel prices by its features.
One of these alternatives is straw pellets.
The production of straw pellets is the most preferred method for hay incineration. Using straw pellets, their delivery to the small capacity boiler furnace can be completely automated.
Pellet production allows to compact the raw material, i.e. compacting hay from 150 to 250 kg/m³ to 600 kg/m³, thus increasing the amount of energy per unit volume, reducing the necessary storage areas and transportation costs.
Straw is an annually renewable source of energy and for this reason they only become more attractive to consumers. The amount of additives is directly dependent on the raw materials used in the collection methods. Using the company’s own straw collection technique, we collect straw just after harvesting, e.g. we try to ensure that straw used for the raw materials would be in great condition, not damaged by rot and other harmful microorganisms. We are working with modern technology which allows to cut straw productively, we also collect only clean straw without any impurities.
We transport straw pressed into rectangular bales to the production base by special transport platforms. Using this technique we can ensure the continuity of the production process, while straw bales are delivered to the warehouse without intermediate storage in open spaces.
Straw bales are stored in the company’s production units’ equipped shelters. Existing conditions alow the pressed straw to keep the required humidity ensuring conditions. Straw is usually delivered into pallets production in bundles. Granulation process requires that the moisture content of the straw would be not more than 15 %. Processed and shredded raw material is primarily transported to the shredder by the transporter. The raw material which has been shredded in the shredder and mill, is delivered to deposition cyclones, storage hopper and falls through the dispenser into the baler chamber.
Straw mass which has been shredded in the granulation device, is compacted under the sway of high-pressure method in high-temperature, using only natural water i.e. water steam for bonding. On the other side of the die cylinders, pressed straw pellets are being cut in order to obtain the desired length of the pellets. High-quality pellets are being separated and the remaining part and dust are returned to production.
