Food additives are typically used in small quantities, have high value, and require extremely high mixing uniformity. Furthermore, they are related to food safety. Therefore, food additive powder mixing machine have very specific requirements.
1. High Mixing Uniformity: Additives usually constitute only a few percent or even a few thousandths of the finished product. They must be highly uniformly mixed with carriers (such as starch, dextrin) or other ingredients to ensure consistent additive content in every batch of the final product.
2. No Cross-Contamination: The equipment must be easy to clean thoroughly to avoid cross-contamination between different batches. This is especially important for allergens or different types of additives.
3. Compliance with Hygiene Standards: Parts in contact with materials must be made of food-grade stainless steel (such as 304 or 316L), with smooth surfaces and no dead corners. Rounded corners should be used for easy disassembly and cleaning.
4. Low Residue: Excellent design should ensure extremely low material residue inside the machine after unloading, guaranteeing batch accuracy and avoiding waste.
5. Gentle Mixing: For certain brittle, crystalline, or shear-sensitive additives, gentle mixing is required to avoid damaging the particle shape.
6. Good Sealing: Prevents dust leakage, protects the working environment, and prevents external contaminants from entering.
1. MR Series Ribbon Mixer
Working principle: Comprised of mixing barrel , spiral ribbon and driven parts. The spiral ribbon is made of two layers. That is, the inner ribbon makes the material move outwards, while the external ribbon makes the material move inwards which forms a good circulation of material. Ribbon moves so circumferentially that the mixer could achieve fine mixing efficiency in a very short time.

Advantages: High mixing efficiency and good uniformity. Can handle materials with slight viscosity or large differences in specific gravity.
2. MR Series Square Conel Mixer
Advantages: Inner wall of the hopper is slippery easy to clean and has no dead angles. The mixer machine can blend in fully closed state and make dust-free environment for production complying with GMP requirements. Blending uniformity reaches up to 99% and the loading capacity quotient reaches between 50% and 80%.

Applications: Additive mixing processes in modern food and pharmaceutical industries where hygiene and automation requirements are high.
3. MR Series Horizontal Plough Mixer
Working principle: Plough or inclind blade is set on shaft, when the mixer machine is running,special structure leads the material to be continuously mixed. With radial and longitudinal movement simultaneously,dead corner is avoided and thus high accurancy mixing is achieved.
