Why does detergent filling present specific constraints?<\/h2>\n

Detergents are a highly heterogeneous product family. A single manufacturer may need to fill products with very different behaviours: fluid foaming washing-up liquid, semi-viscous laundry detergent, corrosive multi-surface cleaner, viscous toilet gel. Each product places different demands on the filling machine.<\/p>\n

A very wide viscosity range<\/h3>\n

Depending on the formulation, detergent viscosity can range from a very fluid liquid (close to water) to a thick gel. This variability requires interchangeable nozzles<\/strong> suited to each product type. Depending on viscosity, filling will be performed by gravity or with the help of a transfer pump.<\/p>\n

Some products are corrosive<\/h3>\n

Certain detergents are corrosive: chlorinated products, acids, bases. These products attack the materials in contact with the liquid, particularly stainless steel. The choice of machine materials is critical to guarantee equipment durability and operator safety.<\/p>\n

A strong accuracy requirement<\/h3>\n

Large doses and the need to comply with legal metrology requirements impose precise and repeatable dosing, regardless of the product being filled. Weight-based dosing meets this requirement better than volumetric or flow-meter dosing.<\/p>\n

Frequent recipe changeovers<\/h3>\n

In multi-product production, recipe changeovers are common. Machine cleanability, ease of disassembly or CIP compatibility, directly conditions line productivity.<\/p>\n

Which filling nozzle to choose for detergents?<\/h2>\n

A machine fitted with interchangeable nozzles<\/strong> is essential to handle an entire detergent range with a single piece of equipment.<\/p>\n

For foaming detergents<\/h3>\n

Prefer a spout nozzle<\/a><\/strong> over a diving nozzle. Simpler to use (no adjustment required), it prevents contamination without reducing throughput.<\/p>\n

For viscous detergents<\/h3>\n

Use flap nozzles<\/strong> suited to the product’s viscosity. For the most viscous products, a mechanical piston dosing system<\/a> is recommended.<\/p>\n

For corrosive detergents<\/h3>\n

Special equipment<\/strong> is required for corrosive and chlorinated detergents<\/a>: inert materials, drip tray, epoxy treatment.<\/p>\n

 <\/p>\n

Which dosing technology to choose?<\/h2>\n

For equipment that is fast, simple and accurate<\/strong>, even on large doses, choose a weight-based<\/strong> filling machine rather than a volumetric or flow-meter system. Weight-based dosing compensates for density variations from one batch to another and guarantees mass accuracy regardless of the formulation.<\/p>\n

For cleanability: choose equipment that is easy to disassemble or that allows clean-in-place (CIP)<\/strong>. On automatic machines, a recovery tray<\/strong> also significantly reduces cleaning time in the event of a line incident.<\/p>\n

 <\/p>\n

Which filling machine to choose based on throughput?<\/h2>\n

More than 14,000 units \/ day<\/h3>\n

A high-speed filling line<\/strong> is the right choice. These lines provide real-time collection of individual packaging data and production data analysis for decision support.<\/p>\n

Between 4,000 and 14,000 units \/ day<\/h3>\n

A filling-capping monobloc<\/strong> combined with a labeller meets the requirement. To simplify format changeovers, components are tool-free removable, this is what is known as plug & play format changeover<\/strong> or SMED.<\/p>\n

Between 3,000 and 6,000 units \/ day<\/h3>\n

Two solutions are possible depending on the number of references and product types:<\/p>\n
