Herm Machinery's latest dedicated double-shaft paddle mixer has many advantages. These feed mixers are very gentle on the product, have low energy consumption, high capacity, low space requirements, and flexible filling. It can be equipped with multiple atomizing nozzles for liquid addition, which is convenient for maintenance. Herm Machinery's newest double-shaft paddle mixer consists of paddles on double shafts mounted in a "W" shaped trough. The specific speed of the shaft, combined with the overlapping motion and paddle design, facilitates fast fluidization and ensures excellent particle transport.
The SLHS mixer can be optionally equipped with multiple liquid spraying systems for the addition of fats, syrups, enzymes, or nutritional liquids. Its easy-cleaning design and reliable performance make it a top choice for modern feed plants.
Each batch completes in 1.5–2 minutes (filling: 20–30s, mixing: 40–60s, discharging: 10–20s), greatly increasing productivity.
✅ 2. Uniform Mixing, Stable Performance
The mechanical fluidization principle ensures homogeneous mixing without layering or segregation. Coefficient of variation (CV) ≤ 5%.
✅ 3. Gentle Processing, Material-Friendly
Low shear during mixing makes it suitable for fragile, lightweight, or fibrous materials, preserving structural integrity.
✅ 4. Energy Saving, Low Operating Costs
Energy consumption is reduced by over 15% compared to conventional mixers, with fewer wear parts and lower maintenance.
✅ 5. Easy Cleaning and Maintenance
Equipped with side inspection doors and observation windows, allowing easy cleaning and quick batch changeover with no residue.
✅ 6. Flexible Liquid Addition
An optional multi-point liquid spraying system ensures even distribution, avoiding clumping and improving liquid absorption efficiency.
✅ 7. Compact Structure, Small Footprint
Ideal for flexible layout in both new and retrofit projects. Easy installation and user-friendly operation.
✅ 8. Reliable Scale-Up to Production
The SLHS Double-Shaft Paddle Mixer features two symmetrically arranged paddle shafts rotating in opposite directions within a “W”-shaped mixing chamber. One shaft pushes the material counterclockwise along the wall, while the other performs a lateral throwing motion. At the intersection of these two flows, a temporary “Zero Gravity Zone” forms. In this zone, materials are suspended in midair, undergoing rapid tumbling, shearing, and diffusion, resulting in a comprehensive, high-speed, and uniform mixing process. Regardless of the material’s shape, particle size, or density, it can be uniformly mixed in a very short time.
The SLHS Series Double Shaft Paddle Mixer is renowned for its efficient, uniform, and gentle mixing capabilities, making it highly versatile across various industries. With flexible configuration options and excellent adaptability, it performs exceptionally well in the following application scenarios:
✅ Feed Industry
