Straw Residue Pulp Belt Press Dehydrators

Straw Residue Pulp Belt Dewatering Machine Equipment Introduction

Characteristics of Straw Residue Pulp:

The fiber length of straw residue (such as crushed wheat, corn, and rice straw) is mostly between 1-5mm, with a fluffy texture and strong toughness. The initial moisture content of fresh straw residue is as high as 85% -95%. If not treated, it is prone to mold growth and odor generation.

Rich in cellulose, hemicellulose, and lignin, as well as small amounts of nitrogen, phosphorus, potassium, and organic matter, it has the basic conditions for conversion into energy, fertilizer, or materials, and the fiber structure is stable with strong degradation resistance.

In traditional processing, straw residue is often burned or randomly piled up, which not only pollutes the air and occupies land, but also may cause fires. But after scientific processing (such as belt dewatering to a moisture content of 55% -70%), it can achieve “turning waste into treasure” and meet the needs of green circular economy.

Advantages of belt press dewatering machine:

Straw residue fibers, thick and long, contain impurities like broken leaves and roots. The belt dewatering machine uses a wide filter belt with a large-pore design to prevent fiber entanglement and equipment blockage. Operators can adjust the filter belt’s speed to match the straw residue’s fluffiness, ensuring smooth feeding.

The belt dewatering machine supports 24-hour continuous operation and maintains straw residue moisture content between 55% and 70% through multi-roll graded pressing (pre-pressing roller + high-pressure roller). After dewatering, the machine compresses straw residue volume by 40%–60%, significantly reducing its weight. This saves warehouse storage space and lowers logistics and secondary processing costs.

The mechanical extrusion dewatering process, gentle and free of high temperatures or intense crushing, preserves the fiber structure of straw residue. The dewatered residue suits applications like organic fertilizers, biogas production, biomass fuels, eco-friendly boards, pulp products, and sewage purification.

For large-scale straw residue processing, the belt press dewatering machine enables continuous feeding and discharging without intermittent shutdowns, aligning with batch production rhythms. Operators can adjust the filter belt’s speed, squeezing roller pressure, and tension to control the moisture content of dewatered straw residue, preventing fiber breakage from excessive squeezing.

Dehydration Principle Of Straw Residue Pulp Belt Dewatering Machine

Transport materials with a moisture content of 80% -90% to the hopper of the dewatering machine through a conveyor, and evenly spread the materials on the filter belt through a spiral feeder. The filter belt moves with the operation of the equipment, and the limit plate scrapes the material layer flat. At the same time, control the thickness of the material to make it completely uniform and consistent;

Then, two fully tensioned circular filter belts are clamped between the material layer, driven by the driving roller. The material is continuously and repeatedly squeezed through the pre press dehydration zone, low-pressure zone, and three sets of pressure roller high-pressure zone to remove a large amount of moisture.

Adjust the extrusion pressure and feeding speed according to different material characteristics to meet customers’ requirements for material moisture.
