Straw pellet machine
Straw pellet machine introduction
Straw pellet machine also called straw pellet mill, is a kind of biomass pellet fuel forming machine using corn straw, cotton straw, soybean straw, rice straw, wheat straw, wood chaff, wood flour, wood chips, rice husks, peanut husks, peanuts and other agricultural waste as raw materials. The pellets made from straw pellet machines can be used in fireplaces, boilers, gasifiers, biomass power plants. The straw pellet machine is divided into flat die straw pellet machine and ring die straw pellet machine.
How to make straw pellet?
When you want to pelletize, the first step is to dry the straw until the moisture is around 15%. The wetter of the straw, it will affect the final quality of the straw pellets. You can make use of the dryer so that you can get the ideal moisture quickly. Or you can dry it naturally if you get enough sunshine.
The second step you have to do is to crush the straw. The straw in its original form is not suitable for direct processing with an straw pellet machine. When you grind it down to a small powder with the crusher, and the straw size is below 5mm, the granulation rate and the straw pellets quality are much better.
The final step you have to get your straw pellet mill or straw pellet production line ready. The method of producing straw pellets is similar to the existing method of producing pellet feed, in which straw is added from inside the equipment ring die and extruded from the ring die by a press roller to form pellets.
First of all, the granule pressing and forming process, the pressure reaches 50-100MPa, the raw materials under high pressure deformation, heating, the temperature can reach 100-120 ℃, the motor drive needs to consume a lot of electrical energy; secondly, the moisture content of raw materials is required in 12% or so, in order to achieve this moisture content, many raw materials have to be dried before they can be used for granulation; secondly, the hot granules need to be cooled before they can be packed.
With the principle of circular motion, the template and rollers are made of high quality alloy steel with special treatment, the spindle and the flat die are driven by the friction, the material is pasteurized at high temperature between the rollers and the template, the protein solidification and denaturation, the particles made by the granule machine are discharged from the die hole under the squeeze of the rollers, the particles are sent out of the machine by the dumping disk, the length of the particles can be adjusted through the cut, it is the preferred model of the breeding farm and professional farmers to reduce breeding costs and improve economic efficiency.
