Paste filling applications and technology selection

Paste filling machines are designed for products that are too thick or viscous to be handled by gravity or standard thin-liquid filling equipment. The key product characteristic is viscosity — pastes typically range from 1,000 cP (thick ketchup) to over 1,000,000 cP (stiff ointments or putties). Suitable products include: food pastes and condiments — tomato paste, ketchup, harissa, chilli sauce, pesto, jam, marmalade, honey, nut butters (peanut butter, almond butter, tahini), mayonnaise, hummus; cosmetic and personal care pastes — body cream, face cream, hair gel, toothpaste, hair dye, sunscreen, lip balm, pharmaceutical ointments; industrial pastes — adhesives, silicone sealants, lubricating grease, thermal paste, electrode pastes. The standard filling technology for paste products is the piston filler — a volumetric piston in a cylinder draws a measured volume of paste and dispenses it into the container. Piston fillers handle the full viscosity range for paste products. For very thick pastes (peanut butter, tahini, thick tomato paste), a product supply system with a positive displacement pump or pressurised hopper pushes product to the piston cylinder inlet to prevent flow-starvation. A heated jacketed cylinder is used for products that stiffen at ambient temperature. Gear-pump fillers use a positive-displacement gear pump to dose product; suitable for medium-viscosity liquids and light pastes, less suitable for very thick, particulate-containing, or shear-sensitive pastes. Peristaltic fillers are used for pharmaceutical pastes where no metal contact with the product is acceptable.

Frequently asked questions

How do I fill peanut butter without air pockets in the jar?

Peanut butter is a high-viscosity paste that traps air easily during filling. The standard technique is bottom-up filling: the nozzle enters the jar to a point near the bottom, begins filling, and retracts upward at a controlled rate as the jar fills, ensuring the nozzle tip remains below the product surface throughout the fill cycle. This displaces air upward and out of the jar rather than trapping it. A positive-displacement piston filler with a heated jacket (peanut butter is easier to fill at 35–40°C) and a bottom-up nozzle retract mechanism is the standard configuration. A deaeration stage on the supply circuit can further reduce air content for a smoother final product surface.

Can a paste filler handle products with chunks or fruit pieces?

Products containing discrete solid pieces (fruit chunks in jam, vegetable pieces in salsa, almond pieces in spreads) require special consideration. A piston filler with a wide-bore cylinder and nozzle can handle chunky products if the particle size is small relative to the cylinder bore — a guideline is that the largest particle should be no more than one-third of the nozzle bore diameter to prevent jamming. For chunky salsas or preserves with large fruit pieces, a special rotary or sliding-disc valve filler design is used to prevent the valve from cutting or trapping pieces. Confirm the maximum particle size and consistency of the product with the machine manufacturer before ordering.

What cleaning is required for cosmetic cream filling machines?

For cosmetic cream filling machines used in a multi-product facility, thorough cleaning between product changeovers is required to prevent cross-contamination of fragrance, colour, and active ingredients. The piston cylinder, valves, nozzles, and product pipework must be disassembled and manually cleaned, or the machine must have a CIP (clean-in-place) capability. For cosmetics manufactured under ISO 22716 (Good Manufacturing Practices for cosmetics), cleaning validation documentation is required to demonstrate that the cleaning procedure removes product residues to below a defined level. Stainless steel product-contact parts with smooth polished finishes and no dead-legs are required for CIP-cleanable cosmetic filling machines.
