All stainless steel · Easy to operate · Easy to clean

1. Project Background

In the United States, producers of nutrition powders, protein blends, bakery premixes and instant drink powders are increasingly focused on very practical requirements for powder mixers:
consistent mixing, easy cleaning, audit-ready design, and simple operation.

The customer’s existing small mixers had exposed several typical issues in daily production:

• Inconsistent batch-to-batch homogeneity, especially for vitamins and trace elements;

• Dead corners inside the mixer, difficult disassembly, and long cleaning time for each recipe change;

• Non-unified materials in contact parts, with some non-stainless components often flagged during customer and third-party audits.

The customer therefore decided to add a dedicated food-grade powder mixer, with clear expectations:

About 300 kg/h capacity, all stainless steel, easy to operate, and quick to clean, suitable for multi-formula, small-batch, high-changeover production.

2. Customer Profile & Application

This US customer mainly produces:

• Nutrition and supplement powders (protein powders, vitamin-mineral blends, etc.);

• Bakery premixes (cake mix, pancake mix, soft bread premixes, etc.);

• Certain functional drink powders and compound seasoning blends.

Typical application needs:

• Small batch sizes but frequent recipe changes every day;

• Clear targets for mixing uniformity, aiming to reduce out-of-spec batches;

• A production environment following strict food hygiene rules, with high requirements on equipment material and cleanability.

3. Our Solution (Configuration & Features)

Considering the customer’s floor space, existing process and daily output plan, we supplied:

A 300 kg/h all-stainless-steel, food-grade powder mixer
designed for medium/small capacity and multi-formula production.

(1) Mixing Capacity & Internal Design

• Planned handling capacity of approx. 300 kg/h, matching the customer’s current order structure;

• High-efficiency mixing element that combines powder tumbling and gentle shear to achieve good homogeneity in a short time;

• Smooth internal wall and rounded transitions on the cylinder and end covers to minimize powder retention and build-up.

(2) All Stainless Steel, Food-Grade Construction

• All product-contact parts are made from 304 stainless steel, with polished surfaces that meet food-contact requirements;

• External surfaces are easy to wipe for daily hygiene and visually present well during audits;

• Sealing and joints are optimized for powder applications, keeping dust escape during operation to a low level.

(3) Easy Operation & Fast Cleaning

• The control panel retains only the essential functions: start, stop, discharge and emergency stop – clear and intuitive, with short operator training time;

• Inspection ports and an openable top cover make it easy to access the mixing chamber for visual inspection and cleaning;

• The discharge outlet and key parts are designed for quick removal, supporting both dry and wet cleaning procedures depending on the plant SOP, which significantly shortens cleaning and changeover time.

5. Initial Customer Feedback

After installation, commissioning and a period of trial production, the US customer shared very positive feedback:

• Improved mixing uniformity
  Test data for the same formula across different batches became more consistent, and the distribution of micro-ingredients is more uniform, reducing rework and scrap.

• Significantly higher cleaning efficiency
  The simple disassembly route and minimal dead zones inside the mixer cut cleaning time notably, allowing more recipe changeovers per day and better flexibility for multi-SKU production.

• Easier audits and customer visits
  The all-stainless-steel structure and good weld/polish quality create a much better impression during brand customer and third-party audits, reducing “equipment-related” remarks.

6. Conclusion

This 300 kg/h all-stainless-steel, food-grade powder mixer exported to the USA was designed around the customer’s real pain points:

stable mixing, easy cleaning, easy operation, and audit-friendly design.

In actual use, it helps the customer to:

• Improve batch stability and formulation consistency across powder products;

• Reduce labor and time cost for both operation and cleaning;

• Build a solid equipment foundation for new product development and stricter customer/third-party audits.

For other North American manufacturers in nutrition powders, bakery premixes and seasoning blends, this type of medium-capacity, all-stainless, easy-clean powder mixer is a practical step up from basic mixing to a standardized, food-grade powder mixing process.
