In the food industry, production lines must handle an increasingly wide variety of products. More references, multiple formats, seasonal recipes, shorter production runs, and specific customer requirements: manufacturers are expected to produce more variants, more often, while maintaining the same level of quality and control.
In this context, industrial cleaning in food production has become a key challenge, particularly during recipe changeovers. This applies both to full production lines and to dosing equipment, with one clear objective: maintaining a high level of hygiene while limiting downtime. Yet this step is still often underestimated. It has a direct impact on line availability, product losses, food safety, and overall productivity.
Between product emptying, cleaning, dismantling, adjustments, and restart, each transition can generate significant downtime. With pasty, viscous, or heterogeneous products, recipe changeovers can become even more sensitive: product residues inside the circuit, longer purging phases, reinforced cleaning, and dosing stabilization during restart.
At Celtech, we believe that a high-performance dosing machine should not only be efficient during production. It should also allow manufacturers to move quickly, cleanly, and efficiently from one recipe to the next.
1. Recipe Changeovers Are Becoming More Frequent
Food production lines now manufacture a wider range of references, often with shorter production volumes. This evolution requires manufacturers to carry out product changeovers much more regularly than before.
On a dosing line, this often involves:
- product emptying phases;
- cleaning operations;
- partial dismantling;
- parameter adjustments;
- quality checks before restarting.
The more frequent these changeovers become, the greater their impact on OEE. The time spent between two recipes can quickly represent a significant share of the line’s total operating time.
In some production areas, the issue is therefore not only production speed. It is also the time lost between two production runs.
2. The Risks of Poorly Controlled Recipe Changeovers
A poorly optimized recipe changeover can quickly become a source of industrial losses.
Risk of Cross-Contamination:
When a line processes several recipes, especially with allergens or different compositions, cleaning becomes critical. A retention area, a circuit that is difficult to empty, or a component that is hard to access can compromise food safety.
Extended Downtime:
Equipment that is complex to dismantle or difficult to clean increases intervention time. The line remains stopped for longer, which directly reduces available production capacity.
Raw Material Losses:
Purging and emptying phases can generate significant product losses. This issue becomes even more sensitive with costly, thick, sticky preparations or products containing particulates.
Unstable Restart:
After a recipe changeover, some lines require several adjustments before returning to regular dosing. This can lead to weight variations, filling defects, or additional stops.
3. Equipment Designed to Simplify Cleaning Operations
Reducing the impact of a recipe changeover does not depend solely on internal procedures. Equipment design plays a decisive role.
At Celtech, we develop dosing solutions designed for the current realities of food manufacturers: multiple recipes, frequent cleaning, shorter production runs, and faster restarts.
Our equipment is designed to facilitate production transitions through several key principles.
An Architecture Designed for Faster Cleaning:
Our dosing machines integrate easy access, quickly removable components, accessible surfaces, and no retention areas.
This design enables operators to intervene more easily between two production runs. It also helps reduce cleaning time and secure hygiene operations, supporting more efficient cleaning of food production lines.
Better Control of Product Losses:
During a recipe changeover, every residual volume can generate product loss. The design of the circuits and dosing technologies helps limit the volumes remaining inside the equipment.
The objective is simple: facilitate emptying, secure cleaning, and reduce losses between two production runs.
Simpler Settings for Faster Restart:
After cleaning, the line must quickly return to stable operation. Simple and accessible settings help reduce the time needed to restart.
This flexibility becomes essential in production environments where frequent changeovers are becoming the norm.
4. Recipe Changeover as a Performance Lever
For a long time, industrial performance was mainly associated with the maximum speed of equipment. Today, this view is no longer sufficient.
A line may be fast during production, but lose a great deal of time between two recipes. In that case, the real performance of the equipment also depends on the transition phases.
An optimized recipe changeover helps to:
- increase actual productive time;
- reduce downtime;
- limit product losses;
- improve production flexibility;
- secure cleaning operations;
- maintain consistent quality despite product diversity.
Performance therefore no longer depends solely on dosing speed. It also depends on the equipment’s ability to support the real rhythm of production.
5. The Celtech Approach: Produce, Clean, Restart
At Celtech, we design dosing machines capable of meeting the constraints of today’s food production environments.
Our solutions are developed to ensure regular dosing, simplify cleaning operations, reduce downtime, and facilitate product changeovers.
This approach is particularly important for manufacturers working with varied recipes, different textures, or complex preparations: sauces, pasty products, recipes with particulates, deli salads, ready meals, or heterogeneous products.
By facilitating transitions between production runs, our equipment enables manufacturers to gain flexibility without compromising hygiene, quality, or dosing stability.
In a context where production diversification continues to accelerate, cleaning and recipe changeovers have become central challenges for food manufacturers.
Reducing transition times, securing cleaning operations, and quickly returning to stable production are now key competitiveness factors.
Dosing equipment should no longer be efficient only during production. It should also enable lines to restart quickly, cleanly, and efficiently between each recipe.
