1. Overview
The Double Paddle Feed Mixer (also known as a dual-shaft paddle blender) is a core mixing device in feed production lines, engineered with a horizontal U-type tank and dual shafts equipped with full-length pitched paddles. Its unique mechanical design drives materials to move in three dimensions—radial, circumferential, and axial—achieving complete, homogeneous mixing in just 30–120 seconds.
With a mixing uniformity (CV value) of ≤5%, it eliminates material segregation regardless of ingredient density, shape, or size. Beyond feed production, it is widely used in food, chemical, fertilizer, and seasoning industries, making it a versatile solution for high-precision batch mixing.
2. Core Value: Why It’s Indispensable in Feed Production
Uniform mixing of feed ingredients directly determines nutritional consistency and animal growth efficiency. The double paddle mixer solves key pain points of traditional mixers, delivering three critical values:
2.1 Ensure Nutritional Uniformity
Feed often requires blending base materials (corn, soybean meal) with micro-additives (vitamins, minerals). The mixer’s three-dimensional mixing action ensures additives are evenly dispersed (CV ≤5%), avoiding selective feeding by animals and preventing nutritional imbalance (e.g., vitamin deficiency in chicks).
2.2 Boost Production Efficiency
With a mixing cycle of only 30–120 seconds per batch, it is 2–3 times faster than single-shaft mixers. This high speed matches the throughput of small-to-large feed production lines (100kg–3000kg per batch), reducing overall production time.
2.3 Reduce Waste & Lower Costs
The full-bottom discharge design minimizes material residue (≤0.5%), reducing raw material waste. Additionally, it consumes 40% less energy than conventional mixers, cutting long-term operational costs for feed factories.
3. Working Principle: Three-Dimensional Mixing for Uniformity
The mixer’s efficiency stems from its advanced dual-shaft paddle structure, which creates a “convection-diffusion-shear” mixing effect:
- Paddle Rotation: Two parallel shafts with pitched paddles rotate at high speed, lifting materials from the U-type tank bottom to the top.
- Three-Dimensional Movement: Paddles push materials radially (between shafts), circumferentially (along the tank wall), and axially (along the shaft length), breaking up agglomerates and ensuring no mixing dead zones.
- Uniform Blending: Within 30–120 seconds, ingredients of different densities (e.g., heavy mineral powder and light bran) are fully integrated, with uniformity reaching CV ≤5%.
- Optional Liquid Addition: Custom atomizing nozzles spray molasses, oil, or liquid additives during mixing, which adhere evenly to powder particles without clumping.
4. Core Features & Advantages
4.1 High Uniformity & Efficiency
- Rapid Mixing: 30–120 seconds per batch, far faster than ribbon mixers (which require 2–5 minutes).
- Consistent Quality: CV ≤5% mixing uniformity, meeting national feed industry standards for micro-additive blending.
4.2 Waste-Reducing & Eco-Friendly Design
- Full-Bottom Discharge: Adopts manual, motor-driven, or pneumatic discharge (three options), emptying materials quickly with minimal residue.
- Dust-Free Operation: Equipped with an air return duct that captures floating powder, preventing leakage and protecting the workshop environment.
4.3 Energy-Saving & Versatile
- Low Power Consumption: Saves 40% energy compared to single-shaft or vertical mixers (e.g., 3kW power for 100kg batches).
- Multi-Industry Adaptation: Suitable for feed, food (seasoning blending), chemical (powdered reagents), and fertilizer (compound fertilizer mixing) industries.
4.4 Flexible & Customizable
- Liquid Addition Option: Install atomizing nozzles to add molasses, oils, or liquid nutrients—critical for high-energy feed or palatability enhancement.
- Multiple Discharge Modes: Choose manual operation (small batches), motor-driven (medium batches), or pneumatic discharge (large-scale automated lines) based on production needs.
5. Application Scenarios
5.1 Feed Industry (Core Use Case)
- Complete Feed Mixing: Blend corn, soybean meal, wheat bran, and premixes for poultry (chicken, duck), livestock (pig, cattle), and aquatic (fish, shrimp) feed.
- Additive Integration: Uniformly mix micro-additives (vitamins, probiotics) or medicaments to avoid local concentration (which may harm animals).
- Liquid- Solid Blending: Add oil or molasses to improve pellet binding and palatability.
5.2 Other Industries
- Food/Seasoning: Mix flour, spices, and additives for snack production or condiment blends.
- Chemical/Mining: Blend powdered chemicals, mineral additives, or construction materials (e.g., dry mortar).
