300 kg/h all-stainless steel mixing, easy operation and cleaning

1. Project Background

In the US, manufacturers of nutritional supplements, bakery premixes, instant beverages and seasoning blends are placing more and more emphasis on three things when it comes to powder mixers:
stable mixing quality, fast cleaning, and food safety compliance.

Many small and mid-sized plants still rely on basic tanks or simple legacy mixers, which often leads to:

• Batch-to-batch variation in homogeneity, especially for micro-ingredients;

• Dead corners, exposed bolts and hard-to-reach areas that are time-consuming to clean and hard to validate;

• Mixed materials in contact parts, which complicate customer audits and third-party certifications.

This US customer wanted to add a dedicated powder mixer as an upgrade to their existing line, focusing on:

Real 300 kg/h working capacity, full stainless-steel food-grade design, and very simple operation and cleaning.

2. Customer Profile & Application

The customer is a US-based producer mainly engaged in:

• Nutritional powders and protein blends;

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

• Functional drink powders and compound seasoning blends.

Typical working conditions and needs:

• Multiple batches per shift, each batch not very large but changeovers are frequent;

• Frequent recipe changes, requiring quick product switchovers and shorter cleaning times;

• A new mixer that can meet FDA expectations for food-contact materials and hygienic design, and withstand customer audits.

3. Our Solution (Configuration & Key Features)

Based on the customer’s capacity, layout and process requirements, we supplied:

A 300 kg/h all-stainless steel, food-grade powder mixer
with simple operation and easy-clean design.

(1) Mixing Capacity & Internal Design

• Designed handling capacity of approx. 300 kg/h, suitable for nutrition powders, premixes and seasoning blends;

• High-efficiency agitator design that combines tumbling and gentle shear to achieve uniform mixing;

• Smooth internal transitions and radiused corners to minimize dead zones and product build-up.

(2) Full Stainless-Steel, Food-Grade Construction

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

• External surfaces are easy to wipe down for daily hygiene;

• Sealing and covers are designed to keep powder escape low, helping maintain a clean production environment.

(3) Easy Operation & Quick Cleaning

• Intuitive control panel with basic and clear functions: start, stop, discharge, emergency stop, etc., making it easy for operators to learn and use;

• Access hatches, lids and discharge outlets are designed for easy opening, allowing quick access to the mixing chamber for inspection and cleaning;

• Supports either wet or dry cleaning procedures (depending on plant SOP), significantly shortening changeover times between products.

5. Initial Customer Feedback

After installation, commissioning and trial production at the US facility, the customer reported:

• More consistent mixing quality
  Batch test results are more tightly grouped, and micro-ingredients are more evenly distributed, improving final product consistency.

• Lower training and operation difficulty
  Production operators quickly learned how to use the mixer, and shift changes require only simple handover for continuous operation.

• Faster cleaning and recipe changeover
  The straightforward internal structure and easy access points significantly reduce cleaning time, allowing more product SKUs to be run in a single day.

6. Conclusion

This 300 kg/h all-stainless steel, food-grade powder mixer exported to the USA is tightly aligned with the customer’s core requirements:
uniform mixing, easy cleaning, audit-ready design, and simple operation.

In actual use, it helps the customer:

• Stabilize product quality and formulation consistency;

• Reduce labor and time costs for operation and cleaning;

• Provide robust hardware support for customer audits and third-party certifications.

For other North American manufacturers of nutrition powders, 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 mixing solution.
