Food-grade 304 stainless steel system for clean, automated powder conveying

Recently, a set of JB-3 dust-free feeding station with vacuum conveyor made of 304 stainless steel produced by our company has been fully debugged, packaged and shipped to Indonesia.
This dust-free conveying system offers a capacity range of 800–2000 kg/h. Made from food-grade 304 stainless steel, it features a simple structure and user-friendly design. The customer connects it to the existing mixer to complete dust-free, automated raw material conveying.

1. Market Background

In Indonesia, the food, spice, seasoning, premix and additive industries rely heavily on powder and granule ingredients. Traditional manual bag dumping and feeding methods often lead to:

• Heavy dust during bag opening and feeding, poor workshop cleanliness and high cleaning effort;

• Operators exposed to dust over long periods, causing occupational health and safety concerns;

• High manual labor intensity for lifting, carrying and feeding into mixers, with limited efficiency and higher risk of error;

• Product loss and recipe deviations caused by open, free-fall feeding.

As companies pay more attention to GMP, food hygiene, worker safety and plant automation, many are now shifting from open manual feeding to sealed dust-free feeding and automatic conveying solutions.

2. Customer Profile & Application

The Indonesian customer is a food-processing plant mainly engaged in:

• Grinding and blending spices, seasonings and marinade powders;

• Producing bakery and instant-food premixes;

• Handling functional food additives and base powders.

Existing process: operators manually open bags → dump powders directly into mixer inlets → mix → discharge and pack.
Key pain points:

• Significant dust emission during bag dumping, requiring frequent cleaning;

• Multiple mixers at different locations, making manual feeding time-consuming and labor-intensive;

• Upcoming hygiene and customer audits require better dust control and cleaner production.

The customer therefore needed a system to centralize bag dumping and feed powders dust-free and automaticallyinto the existing mixer, without a full rebuild of the current production line.

3. Our Solution (Configuration & Key Specifications)

Based on the customer’s layout and process, we supplied a complete set of:

JB-3 Dust-Free Feeding Station + Vacuum Conveyor (Food-Grade 304 Stainless Steel)

• Model: JB-3 dust-free feeding station with vacuum conveying system

• Material: All product-contact parts are made of 304 stainless steel, suitable for food applications;

• Capacity: approx. 800–2000 kg/h (depending on material and conveying distance);

• Key features:

  • Dust-free feeding: bag opening and dumping are carried out inside a sealed chamber, with dust collected by a filtration system;

  • Vacuum conveying: powders are transferred from the feeding station to the existing mixer through a closed pipeline using negative pressure;

  • Simple structure: modules are easy to dismantle and clean, ideal for frequent product changeovers;

  • Easy integration: designed to connect directly to the customer’s existing mixer without major plant modification.

Key Technical Data (Excerpt)

All equipment was fully tested in-house, including vacuum conveying performance and simulated feeding, then protected and packaged according to export standards before shipping to Indonesia.

4. Expected Benefits for the Customer

Considering the customer’s production rhythm and management goals, the JB-3 dust-free feeding station with vacuum conveyor is expected to deliver:

• Significantly reduced dust and a cleaner workshop
  Bag dumping and feeding are now enclosed in a sealed chamber, with dust captured by the filtration system instead of dispersing into the plant.

• Lower operator workload and improved safety
  Operators work at floor level for bag opening and feeding, while the vacuum system automatically conveys material to the mixer, reducing lifting, climbing and injury risks.

• More stable and controllable dosing and conveying
  Compared to manual feeding, vacuum conveying offers more stable throughput and better control over actual feed quantities, helping minimize product loss and formulation deviations.

• Better readiness for audits and certification
  The dust-free and closed conveying solution supports future hygiene, food safety and customer audits, enhancing the plant’s overall image and compliance level.

5. Conclusion

This JB-3 dust-free feeding station with 304 stainless steel vacuum conveyor, exported to Indonesia, enables the customer to upgrade from manual open feeding to dust-free automated conveying without changing the core mixing process:

• Capacity range of 800–2000 kg/h meets current demands and allows for moderate growth;

• Food-grade 304 stainless steel and a simple, low-residue design make daily cleaning and maintenance easier;

• Closed vacuum conveying reduces dust, lowers labor intensity and supports higher levels of automation and standardization.

For other Southeast Asian food, spice, seasoning and additive plants handling powdered ingredients, this type of “dust-free feeding station + vacuum conveying + existing mixer integration” is a practical and scalable option to improve dust control, workplace safety and production efficiency.
