Powder sieving in industrial baking: reduce foreign contaminants and cleaning time by 50%.

In the industrial baking sector, managing powdered ingredients (flour, sugar, yeast) is a major challenge.

The presence of foreign bodies from bags, food hygiene constraints, and the physical strain of handling can impact product quality, productivity, and operator safety.

This customer case illustrates how the installation of an industrial sieve for food powders, such as the Safetip® C-Flex, in an ingredient receiving line makes it possible to secure raw materials as soon as they are introduced into the process. This bag dumping solution with integrated sieving helps to improve food safety, reduce cleaning time, and optimize workstation ergonomics in industrial bakeries.

The client is an industrial bakery specializing in the production of frozen bread and pastries, supplying supermarkets and catering networks.

Production relies on the daily use of large quantities of flour, sugar, yeast, and other powdered ingredients.

These raw materials are received in bags and then dumped into the production process. During this step, packaging fragments (paper, fibers, plastics) can sometimes enter the ingredients, creating a risk to product quality and food safety.

The objectives of this project were as follows:

1. Ensure food safety by removing any foreign bodies from the bags through the installation of an industrial sieving system capable of capturing contaminants from ingredient bags before they enter the process.
2. Reduce cleaning time between batches (product type or origin changes) with a solution that enables quick equipment disassembly.
3. Improve working conditions for operators (less lifting, less effort, better ergonomics) by minimizing repeated handling of ingredient bags to reduce physical strain.

To address these challenges, a Safetip® C-flex was installed in the ingredient receiving area. This bag dumping sieve allows food powders to be filtered directly as they are introduced into the process.

Powder sieving with a 3 mm mesh:

The machine is equipped with a 3 mm mesh sieve to prevent the introduction of small debris from bags and effectively retain:

• pieces of paper from bags,
• fibers or plastic packaging,
• small debris or contaminants.

The system thus ensures effective sieving of food powders before entering production.
 

Adjustable vibrating motor according to powder type:

The vibrating motor can be adjusted depending on the type of powder:

• gentle vibration for free-flowing powders like flour,
• stronger vibration for denser materials like sugar.

This adjustment optimizes throughput, flow, and the efficiency of industrial sieving.
 

An ergonomic workstation for bag dumping:

To improve working conditions, the solution integrates several ergonomic features:

• adjustable deposit table with height adjustment,
• spring-assisted door to facilitate bag handling.

Operators can thus empty bags with less physical effort and maintain better working posture.
 

Safety and dust management (ATEX and dust extraction):

To ensure a safe production environment, the solution can be equipped with:

• an ATEX-compliant version for areas at risk of dust explosions,
• a dust extraction system to prevent airborne emissions.

This helps maintain a cleaner and safer working environment.
 

Quick cleaning and simplified maintenance:

In the food industry, ease of cleaning is essential. The machine is designed to simplify maintenance and hygiene operations:

• quickly removable sieve,
• accessible hopper,
• compatible with high-pressure washing.

The installation of our Safetip C-flex sieving solution provided several benefits.
 

Reduction of foreign bodies in ingredients:

Upstream sieving almost completely eliminated packaging fragments in the powders.
Result: better product quality and fewer defects in production.

Enhanced compliance with food safety standards:

Contaminant control improves:

• food safety,
• compliance with food industry standards,
• success in quality and hygiene audits.

Up to 50% time savings on cleaning:

Thanks to the removable design and accessible components: cleaning and product changeover times were reduced by 40 to 50%. This directly improves production line availability.

Improved working conditions for operators:

The ergonomic workstation allows for:

• reduced handling,
• less physical fatigue,
• lower risk of injuries from lifting bags.
