Straw pellets are prepared by adding straw from inside the ring die of a pellet machine and extruding the straw from the ring die by a press roll to form strip pellets. The cellulose and lignin contained in the straw and other materials (lignin increases the softening and bonding force when the temperature reaches a specific value, and makes the cellulose molecular group misplace, deform and extend under a specific pressure, and the adjacent biomass pellets in the interior are connected to each other, recombined and pressed), pressing the straw into pellets.

The role of straw pellets:

1. Used as heating system fuel

Straw pellets are an environmentally friendly clean energy source with high calorific value, high density, low moisture content, long burning time and easy storage and transportation. Its combustion results in zero emissions of carbon dioxide and sulfur dioxide, and the ash after combustion can also be used as a mineral fertilizer for plant grow1.

2. Use as bedding for animals

The soft straw pellets have the characteristics of hygroscopicity, accelerating purification, reducing cost, reducing dust pellets in the air and controlling ammonia odor. When used as animal bedding, only the soiled parts need to be replaced every day, and the bedding can also be used as fertilizer in farms1.

3. Used as pellet feed for livestock

Feed pellets have high hardness, smooth surface and sufficient internal maturity, thus promoting the digestion and absorption of nutrients, and common pathogenic microorganisms and parasites can be killed, feeding animals is convenient and clean, and can obtain higher profits compared with mixed powdered feed      

Straw pellets require several pieces of equipment, depending on several factors:

1.Raw material status. Different raw material moisture content and characteristics in the particle production will use different process flow, matching equipment is also different

2. output requirements. Higher production requirements may require larger units or a combination of units

3. the degree of automation, environmental protection requirements. Environmental requirements also affect the configuration of the device, such as whether a dust removal device is required

The simplest production line only needs a pellet machine + a conveyor.

Complex production lines require crusher + crusher + dryer + screening machine + granulator + cooler + packaging machine + silo + conveyor + dust removal equipment. Each kind of equipment, according to the output can be bought a combination of multiple use.

For small or preliminary users, we can easily choose a simpler device combination

So the amount and type of equipment needed to make pellets from straw depends on your specific needs, raw material characteristics and expected yield. You can go to our website granule production line section to see, you can also consult us directly.
