Tomato paste, ketchup, mayonnaise and sauces are thick products; some contain particles and are sensitive to air bubbles. To avoid voids in the package and keep the neck clean, the filling method is chosen for the product's consistency.
Filling sauces and paste
- Servo volumetric filling: measures thick products repeatably by volume.
- Cut-off nozzle: breaks the product stream cleanly at the end of the fill and prevents stringing.
- Jars, bottles and buckets: linear and rotary filling for small packs; the bucket filling and closing machine for large packs.
On ketchup and mayonnaise bottles, capping and labelling run on the same line.

Hygiene
All product-contact surfaces are AISI 316L stainless steel, and the balance tank can be cleaned in place (C.I.P.). Parts that can be removed without tools shorten cleaning and product changeovers. For hygiene criteria on food lines, see our food and beverage page.
Capping and the line
For capping, gripper, three-ball, pick & place, flat clamping, rolling and press systems are available, driven by servo torque, asynchronous motor, mechanical torque or air motor. Caps are fed to the station by an elevator, vibratory bowl or rotary table. On a fully automatic line, the bottle feeding table, air bottle cleaning, filling, capping, labelling, check weigher, metal detector and inkjet date coding run in sync on the same conveyor.
