Pea Straw Pelletizer

Brief Introduction

Pea stalks have a higher protein content than most grass straws, but the material is fine and brittle, producing a lot of dust. Ordinary pelleting equipment is prone to dust overflow, loose pellets, and powder shedding. Pea stalk pellet mills are specifically optimized for the legume fiber characteristics of pea stalks, processing harvested pea stalks into compact feed or fuel pellets. Pea stalk pellet mills are suitable for pea planting cooperatives, forage processing plants, and cattle and sheep ranches, utilizing field pea stalks locally and solving the problems of poor storage and easy mold growth. The equipment can be connected to a complete set of auxiliary equipment for crushing, dust removal, and cooling, establishing a complete pea stalk pellet production line, transforming field by-products into commercial pellet products, meeting the dual needs of livestock feed supply and biomass energy production.

Working Principle

After being crushed, dust-removed, and with the required moisture content, the pea stalk material is fed into the pelletizing chamber of the pea stalk pelletizer. The power unit drives the pressure roller to operate continuously, creating a high-pressure extrusion environment between the pressure roller and the ring die. Under the extrusion friction, the pea stalk heats up, and the internal fibers and polysaccharides soften. No external adhesive is needed; the material itself binds and forms the pellets. The material is continuously pressed into the ring die hole and extruded outward. The machine cutter cuts the strip-shaped material into standard-sized pea stalk pellets. The finished pellets are discharged from the outlet and, after cooling and solidification, can be directly bagged and stored.

Suitable Raw Materials

Core raw material: Pea stalks

Compatible raw materials: Broad bean stalks, chickpea stalks, various legume vines, alfalfa, miscellaneous forage grasses, wheat straw, and other agricultural and forestry biomass.

Material requirements: Raw materials must be pre-crushed and screened to remove soil and impurities. Moisture content should be controlled at 11-16%. Impurities must be thoroughly filtered to reduce wear on the ring die rollers of the pea stalk pellet mill.

Application Areas

1. Grass-fed livestock farming: Pea straw pellet mills process forage pellets for use as roughage in cattle, sheep, and deer, improving palatability and reducing feed spoilage due to mold.

2. Commercialized forage pellet processing: Pea straw is recycled in major bean-producing areas, processed into finished forage pellets, and sold externally, expanding revenue from agricultural product processing.

3. Biomass clean energy: Pea straw pellet mills produce fuel pellets for use in heating boilers and drying equipment, serving as environmentally friendly renewable fuel.

4. On-farm processing: Large-scale cattle and sheep farms are equipped with pea straw pellet mills to process pellets on-site, reducing the cost of purchasing forage.

5. Organic fertilizer and cultivation substrate: Pea straw pellets are used as fermentation substrate to produce organic fertilizer and seedling substrate, achieving the recycling of straw back to the field.

Details

1. HUIXIN Gearbox: Heavy-duty HUIXIN gearbox provides adaptive torque to cope with variable resistance of flexible pea straw fiber and pod fragments.

2. Rotating bracket: This reinforced design dampens vibration caused by inconsistent, low-density straw feed.

3. Reducer: Precision matched reducer maintains stable power transmission while processing flexible, easily tangled pea straw strands.

4. 304 Stainless Steel Dust Cover: 304 stainless steel construction offers great resistance against abrasion and mild corrosion by grass ash and coarse fiber dust.

5. Internal lifting knife: Built-in internal lifting knife cuts tangled straw clumps and prevents fiber bridging in the pelletizing cavity.

6. Adjustable blades: Adjustable blades calibrate feed thickness to suit the lightweight, branching fibrous characteristics of dried pea straw.

Unique Advantages

1. Machine assembly: Custom ring die and roller clearance optimized for delicate legume straw, reducing fiber winding and feed blockage.

2. HUIXIN gearbox: Tuned HUIXIN gearbox with good anti-fluctuation performance, running more stably under unstable pea straw feeding than ordinary gearboxes.

3. Stainless dust cover: This one-piece dust cover is constructed from 304 stainless steel as an alternative to painted carbon steel. It delivers reliable resistance against abrasion and weak acid corrosion for extended service in harsh working environments.

4. Bottom feeding reducer: Improved under-feed reducer prevents pea straw fiber from arching and clogging the feed inlet.

5. Cooling system: Gentle circulating air cooling reduces pellet fragility and lowers breakage and powder rate of lightweight pea straw pellets.
