Double spiral cutting and conditioning machine consists of two interlaced spiral shafts, combined with high-speed rotating cutters, to push, stir, break up and homogenize the materials. It is particularly suitable for materials containing fibers, high viscosity, many impurities or high moisture content. Double spiral cutting and conditioning machine usually uses spiral blades to achieve cutting, stirring, mixing or conditioning of the supply. The counter-rotating shear force and propulsion force of the spiral blades can efficiently handle viscous, block or powder supplies.

Working principle of double spiral cutting conditioning machine

The working principle of double spiral cutting and conditioning machine is based on the rotation of spiral blades. The specific working process is as follows:

The material enters the equipment from the feed port, and the double spiral shaft pushes the material forward while turning and stirring

The rotating blade cuts the long fibers, weeds, plastics, packaging bags and other foreign objects in the material into small pieces

The conditioned material is uniform, entangled, and suitable for dehydration or fermentation

Finally, it is output from the discharge port to the next processing equipment (such as solid-liquid separator, fermentation bin, etc.).

Structure of double spiral cutting and conditioning machine machine

Double spiral cutting and conditioning machine is usually composed of a casing, a double spiral shaft, a cutting tool, a drive device, a feed port and a discharge port. The double spiral shaft is equipped with spiral blades and cutting tools. The spiral blades are used to push the material forward, and the cutting tool cuts the material. Its core structure is a double spiral shaft design, which realizes the transportation, mixing and cutting of materials through the rotation of spiral blades, and has the characteristics of high efficiency, uniformity and adjustability.

Double Spiral Cutting And Conditioning Machine Benefits

Material handling during processing, especially in continuous systems such as extrusion, presents many challenges. Double spiral cutting and conditioning machines are designed to address many of these issues, ensuring smoother, more efficient material flow and preparation.

Addressing feed rate and flow inconsistency

Raw materials, especially powders and blends with varying particle sizes or moisture content, can have inconsistent flow properties, resulting in uneven feeding. Double spiral cutting and conditioning machines use the positive conveying action of intermeshing twin screws to ensure a more stable and controlled feed rate.

Addressing poor mixing and poor uniformity

Inadequate mixing can lead to inconsistent moisture content, temperature and ingredient distribution, which directly affects the quality and characteristics of the final product. The intermeshing action of the double spiral cutting and conditioning machine ensures that the solid and liquid components are evenly mixed before entering the equipment.

Handling sticky or difficult materials

Some raw materials can stick to the screw and barrel in a single screw system, causing blockages and reducing conveying efficiency.

Double spiral cutting and conditioning machine’s positive conveying, centerless shaft design, and self-cleaning capabilities minimize material buildup on the screw and barrel.

Dealing with Bridging and Blockage Issues

Powdered and granular materials can sometimes form bridges or blockages at the inlet or within the conveying section of a single screw system, interrupting material flow. Double spiral cutting and conditioning machine mechanically moves material forward, reducing reliance on gravity flow and minimizing issues caused by bridging or rat-holing in the hopper.

Difference between Double spiral cutting and conditioning machine and Single Screw

Shear Force	Higher	Lower
Self Cleaning	Better	Less Effective
Complexity and Cost	Higher	Lower
Typical Applications	Demanding Complex Materials	Less Demanding Materials

Applications of double spiral cutting and conditioning machine

Double spiral cutting and conditioning machine is widely used in the following production:

Animal Feed: Preparation of raw materials for pelleting or extrusion into animal feed, pet food and aquafeed. The conditioning process improves the quality, digestibility and water stability of the pellets.

Food: Pre-treatment of materials for the production of breakfast cereals, snacks, pasta and textured vegetable proteins. The pre-treatment process affects the texture, expansion and cooking characteristics of the final product.

Other Industrial Applications: Double spiral cutting and conditioning machine may be used in other industries that require thorough mixing and pre-treatment of materials before further processing.

Double spiral cutting and conditioning machine is a critical piece of equipment that utilizes the action of intermeshing twin screws to mix the raw materials before they enter the twin screw extruder for processing, ultimately affecting the quality and characteristics of the final product.
