How Leading Sauce Manufacturers Build Agile Production Lines?

Many food manufacturers discover too late that flexibility cannot simply be “added” to an existing production line. It must be engineered from the very beginning. Historically, filling equipment was designed around a single objective: maximum throughput. The assumption was simple. Produce one product or two. Use two or three bottles. Run for several days. Repeat.

That philosophy made perfect sense twenty years ago. Today, however, it no longer reflects reality.

Sauce manufacturers can produce:

• 150 g squeeze bottles
• 250 g glass jars
• 500 g PET bottles
• Organic recipes
• Vegan formulations
• Chunky sauces
• Smooth emulsions
• Premium products
• Retail formats

all on the same production line. The objective has therefore changed. Instead of maximizing production speed, manufacturers increasingly seek to maximize productive time.

1- Fast Changeovers

Every minute spent changing products is a minute when the factory generates no revenue. This makes changeover time one of the most expensive “hidden costs” in manufacturing. Yet many plants still accept long changeovers as unavoidable.

The most efficient manufacturers think differently.

Instead of asking:

“How long does a changeover take?”

they ask:

“Why does it take this long?”

The answer often reveals opportunities for improvement.

Typical causes include:

• manual mechanical adjustments
• multiple tools
• operator-dependent settings
• lengthy cleaning sequences
• manual documentation
• repeated quality checks

Modern filling systems reduce these delays through:

• servo-controlled adjustments
• automatic positioning
• stored production recipes
• digital parameter recall
• quick-release components
• tool-less format changes

The result is not only shorter changeovers but also greater repeatability. Operators spend less time adjusting equipment and more time producing saleable products.

Applying SMED Principles to Sauce Manufacturing

One of the most effective methodologies for reducing changeover time is SMED (Single-Minute Exchange of Dies), originally developed by Shigeo Shingo for the automotive industry.

Although conceived for stamping presses, the principles translate remarkably well to food manufacturing.

SMED encourages manufacturers to:

• separate internal and external activities
• prepare the next product before production stops
• standardize adjustments
• eliminate unnecessary movements
• simplify operator tasks

For a sauce producer, this might involve:

• Preparing bottles before the current batch finishes.
• Pre-loading recipes into the HMI.
• Organising caps and labels in advance.
• Using colour-coded change parts.
• Reducing operator intervention.

Each improvement may save only a few minutes. Across hundreds of changeovers each year, however, the cumulative gain becomes substantial.

2- Multi-Viscosity Filling

Few food categories exhibit as much viscosity variation as sauces.

Consider the difference between:

• Soy sauce
• Mayonnaise
• Pesto
• Honey mustard
• Tomato ketchup
• Hummus
• Chunky salsa

Each behaves differently inside the filling system. Some products flow freely. Others contain herbs, seeds or vegetable pieces.Some foam easily. Others trap air. Some become significantly thicker as temperature changes.

Designing one filling system capable of handling a lot of type of sauces requires much more than increasing pump power.

It requires:

• stable product flow
• accurate metering
• gentle handling
• consistent pressure control
• minimal shear
• repeatable dosing

The wider the viscosity range, the greater the engineering challenge.

Product Behaviour Matters More Than Product Name

Manufacturers often classify products by commercial category. Engineers classify them by behaviour. Two products may both be labelled “barbecue sauce.” One may behave like ketchup. The other may resemble a chunky marinade.

Similarly, two mayonnaise recipes may exhibit completely different rheological properties because of oil content, stabilisers or temperature.

Successful flexible production lines therefore adapt to product behaviour rather than product category.

3- Multi-Format Packaging

Consumers increasingly expect packaging options that match different occasions. A single recipe may be marketed in:

• 250 g squeeze bottle
• 450 g PET bottle
• 500 g glass bottle
• 1 L family bottle
• 5 L foodservice container
• Export packaging
• Retail packaging
• Promotional packaging

Each format introduces new challenges.

• Bottle height
• Bottle diameter
• Neck diameter
• Closure type
• Label position
• Carton dimensions

Without a flexible filling line, manufacturers may require separate equipment for each format. That approach quickly becomes expensive. Instead, leading producers seek equipment capable of accommodating a broad range of containers with minimal adjustment.

Why Packaging Standardisation Matters?

An often-overlooked strategy involves reducing unnecessary packaging complexity. Many manufacturers unintentionally create dozens of unique bottle and cap combinations. Standardising certain components can dramatically simplify production.

Examples include:

• Using identical neck diameters across several bottles.
• Sharing cap families.
• Reducing label dimensions.
• Using modular bottle designs.

Packaging decisions therefore influence manufacturing flexibility long before production begins.

4- Digital Recipe Management

The most advanced factories increasingly rely on digital production recipes. Instead of manually adjusting equipment for each product, operators simply select: “Ketchup 500 g.”

The system automatically recalls:

• Filling volume.
• Pump speed.
• Pressure.
• Nozzle position.
• Container height.
• Cap torque.
• Reject limits.
• Quality parameters.

Digitalisation Supports Consistency

One of the greatest advantages of recipe management is repeatability. Without stored recipes, two operators may configure the same product differently. With digital recipes, the machine reproduces identical settings every time. Consistency becomes independent of operator experience. This is particularly valuable for manufacturers operating multiple production shifts or multiple factories.

5- Hygienic Design

Flexibility must never compromise food safety. As product portfolios expand, cleaning becomes increasingly important.

Especially with:

• Clean Label products.
• Organic sauces.
• Egg-based emulsions.
• High-oil formulations.
• Allergen-containing recipes.

Frequent product changes increase cleaning frequency.Poor hygienic design therefore has a direct effect on productivity.

hygienic engineering seeks to minimise:

• dead zones
• product retention
• manual cleaning
• water consumption
• chemical usage
• downtime

The objective is simple:  Clean faster. Clean better. Return to production sooner.

The factories that will lead the next decade of sauce manufacturing are unlikely to be those with the highest filling speeds.

Instead, they will be the factories capable of introducing a new product next week, changing bottle formats tomorrow, switching recipes this afternoon and maintaining filling accuracy throughout all without sacrificing food safety or profitability.

Flexibility is no longer simply an engineering objective. It has become a strategic business capability.  The manufacturers that master it will respond faster to retailers, launch products more quickly and adapt more effectively to changing consumer expectations.

Frequently Asked Questions

How can I design a production line suited to an environment with a large number of SKUs?

A production line for a high-SKU environment should be designed to absorb frequent changes in recipes, viscosities, packaging formats, and production schedules without creating excessive downtime. This requires more than a flexible filling machine. Manufacturers should consider the entire production process, including product behavior, packaging standardization, changeover procedures, cleaning, digital recipe management, quality control, and future equipment upgrades. Flexibility is most effective when it is engineered into the line from the beginning.

What criteria should be considered when selecting filling equipment designed for a wide range of products?

Manufacturers should evaluate products according to their physical behavior during filling, not simply their commercial category. Important parameters include viscosity, particle size and content, foaming tendency, temperature sensitivity, flow characteristics, and pressure requirements. A filling system designed for a diverse sauce portfolio should maintain consistent dosing accuracy and product handling across products ranging from smooth sauces and emulsions to thicker or particulate-containing recipes.

 How can a production line handle multiple bottle, jar and closure formats efficiently?

Packaging flexibility depends largely on reducing the number and complexity of adjustments required between formats. Servo-controlled positioning, standardized adjustment mechanisms, modular container handling, quick-release components, tool-less changes, and digitally stored configurations can help operators switch between bottles, jars, and closures more efficiently. Manufacturers can also reduce complexity by standardizing elements such as neck finishes or closure families across several SKUs whenever possible.

Why is hygienic design important for production flexibility in sauce manufacturing?

In a high-SKU environment, more product changes generally mean more frequent cleaning. Hygienic equipment design can reduce the time required between recipes by minimizing dead zones, residual product retention, difficult-to-clean assemblies, and manual cleaning operations. Efficient drainage and optimized product circuits can also support faster Cleaning-In-Place (CIP) cycles. As a result, hygienic design contributes both to food safety and to higher equipment availability.

 How to future-proof a new filling and packaging line?

Manufacturers should avoid designing a production line exclusively around today’s product portfolio. A modular production platform can provide greater flexibility to integrate future filling stations, new closure systems, inspection technologies, automation, or other equipment as requirements evolve. Combined with digital recipe management and adaptable mechanical architecture, modularity can help manufacturers introduce future SKUs and packaging formats without having to replace the entire production line.
