Wuxi Hasen Import and Export Co., Ltd  |  www.immyhitech.com

Running a profitable grain milling, animal feed, or food processing operation demands more than a single capable machine. It demands a full suite of equipment that works in concert — each unit precisely matched to the production stage it serves, and each capable of meeting the throughput, quality, and reliability standards that modern processing lines require. Wuxi Hasen Import and Export Co., Ltd, a China-based machinery manufacturer with over 30 years of experience in grain, oil, and feed equipment, offers exactly that: a cohesive lineup of processing machines engineered for demanding industrial environments and backed by full project integration capability.

This article profiles six of Wuxi Hasen's core equipment offerings — the Double Door Open Hammer Mill, SLHY Screw Mixer, STZW Micro Control Feed, SFJH Planar Rotary Grading Sifter, Dust Vibration Cleaner, and SCY Cylindric Sifter — each a specialist in its role, each integral to a complete and efficient processing line.

1. Double Door Open Hammer Mill — High-Efficiency Size Reduction

The Double Door Open Hammer Mill is engineered for intensive granular material crushing in grain and feed processing environments. Its defining structural feature — the double-door opening design — revolutionizes maintenance access. Both sides of the crushing chamber open fully, allowing operators to reach the hammer blades, screen plates, and rotor assembly without disassembling the machine or working in confined, awkward positions.

This design addresses one of the most persistent pain points in conventional hammer mill operation: downtime during screen changes and hammer replacement. In a high-throughput feed mill where the crusher is a production bottleneck, every minute of maintenance downtime carries a direct cost. The double-door configuration reduces screen change time dramatically, keeping the line running.

Beyond maintenance efficiency, the machine delivers:

• High crushing throughput suitable for corn, wheat, sorghum, rice husk, and other granular feed and grain materials.

• Uniform particle size output governed by interchangeable screen plates, allowing operators to dial in the grind specification for each batch or product formulation.

• Robust rotor and hammer construction for continuous-duty operation in around-the-clock feed mill environments.

• Low vibration operation through dynamically balanced rotor design, extending bearing life and reducing structural fatigue on the installation frame.

2. SLHY Screw Mixer — Precision Blending for Feed and Food Formulations

Mixing is the stage where a feed or food formulation either comes together or falls short. Inadequate mixing homogeneity means nutrient variation across a batch — a problem that directly impacts animal performance in feed applications, and product consistency in food manufacturing. The SLHY Screw Mixer is designed to eliminate that risk through its twin-screw horizontal mixing technology, which achieves exceptionally uniform blending of dry ingredients across a wide range of particle sizes and bulk densities.

The SLHY series is purpose-built for feed mills, flour processors, and food ingredient manufacturers who require consistent, repeatable batch quality. Key operational characteristics include:

• Short mixing cycles that support high-throughput batch production without sacrificing blend uniformity — critical in facilities where mixer capacity limits line output.

• Gentle screw action that minimizes particle degradation during mixing, preserving the particle size distribution achieved upstream by the hammer mill or roller mill.

• Easy discharge and cleanout design, reducing cross-contamination risk when switching between formulations or ingredient batches.

• Wide compatibility with premixes, concentrates, vitamins, trace minerals, and liquid micro-additions such as oil or molasses, making the SLHY a versatile blending platform across product types.

3. STZW Micro Control Feed — Intelligent, Precise Material Metering

In any automated processing line, the ability to deliver precise, consistent quantities of material to downstream equipment is foundational to production stability and recipe accuracy. The STZW Micro Control Feed unit provides exactly this capability — a precision material metering and feeding solution designed for integration into continuous processing lines where controlled, repeatable material flow rates are critical.

The STZW series serves multiple roles within a processing facility:

• Controlled ingredient dosing for automated batching systems, ensuring each formulation cycle receives the correct quantity of each ingredient within tight tolerance.

• Consistent feed rate control to downstream mixers, presses, or extruders, preventing surge loading that causes downstream equipment to underperform or trip on overload protection.

• Micro-ingredient addition support, where small quantities of high-value additives must be metered accurately to maintain formulation compliance.

• Integration with plant control systems through standard interfaces, supporting the move toward intelligent, automated, and digitally monitored processing facilities that Hasen actively supports through its intelligent plant solution portfolio.

4. SFJH Planar Rotary Grading Sifter — Multi-Fraction Particle Classification

Size classification is as important as size reduction in grain and feed processing. The SFJH Planar Rotary Grading Sifter performs multi-layer, multi-fraction classification of granular and powdered materials — separating the product stream into distinct size fractions simultaneously through its stacked sieve deck configuration and planar rotary motion.

Unlike linear vibrating sifters, the planar rotary motion of the SFJH creates an even, gentle material flow across the full sieve surface, maximizing sieve utilization and minimizing blind spots. This results in:

• Higher sieving efficiency and accuracy, with clean separation between fractions and minimal misplaced material in over- or under-size streams.

• Multiple simultaneous outputs from a single machine, reducing the number of classification units required in a processing line and simplifying material flow routing.

• Smooth, low-vibration operation that is gentle on friable materials where particle integrity must be maintained through the classification stage.

• Wide applicability across grain, feed pellets, flour, starch, and granulated food ingredients — making the SFJH a versatile classification platform for multi-product facilities.

5. Dust Vibration Cleaner — Raw Material Pre-Cleaning and Quality Assurance

Material quality at the intake stage determines product quality at the output stage. The Dust Vibration Cleaner is designed to remove surface dust, fine impurities, and lightweight foreign materials from incoming granular raw materials before they enter the primary processing flow. By intercepting contamination at the earliest possible stage, the machine protects downstream equipment from accelerated wear and ensures that the milling, mixing, and classification stages work with the cleanest possible input material.

In grain intake operations — where incoming corn, wheat, soybeans, or rice may carry harvest and transport debris — the Dust Vibration Cleaner provides:

• Efficient vibrating screen separation of dust, chaff, and fine impurities from the bulk grain stream, reducing the burden on downstream dust collection systems.

• Removal of lightweight impurities through aspiration channels integrated into the cleaner design, achieving cleaner output without wet washing or chemical treatment.

• High throughput capacity suitable for raw material intake operations where the cleaner must process material as fast as it arrives from trucks, silos, or conveyors.

• Simple maintenance and screen replacement, minimizing downtime at the critical intake stage of the production line.

6. SCY Cylindric Sifter — Continuous Screening for Process Flow Applications

The SCY Cylindric Sifter brings a different sieving geometry to the processing line — the rotating cylinder (trommel) design — which is particularly well suited to continuous-flow screening applications where material must be classified without interruption and with minimal operator intervention. The cylindrical screen rotates steadily, advancing material along its length while allowing undersized particles to pass through the screen mesh and retaining oversized material for discharge at the far end.

The SCY series is widely used in grain, feed, food, and chemical processing for:

• Pre-screening of incoming raw materials to remove oversized lumps or foreign objects before hammer milling or roller milling, protecting these high-value machines from damage.

• Post-process screening of granulated or pelleted products to separate fines from on-specification pellets, improving finished product uniformity and grade.

• Continuous-duty classification in automated processing lines where stopping the sifter for cleaning or maintenance is operationally unacceptable.

• Low maintenance operation — the rotating cylinder design is mechanically simple, with few wear parts and easy access for screen replacement.
