Food depositing machines — operation and types

A food depositor accurately portions a set volume or weight of liquid, semi-liquid, or viscous food product into a tray, cup, jar, or baking tin. Depositors are used in ready meal tray filling (depositing sauce, gravy, or soup components into meal trays), bakery production (depositing batter into cake tins, cream into pastry, jam into tarts), and confectionery (depositing gummy, hard candy, or chocolate masses into moulds). The main types include: piston depositors (a hydraulic piston withdraws from the cylinder to draw product in, then advances to push a precise volume into the container or mould — accurate and suitable for thick, chunky, or particulate products); pump depositors (peristaltic, gear, or rotary lobe pumps meter the product continuously or in controlled pulses — suitable for flowable liquid products and for continuous production); and time-pressure depositors (the valve opens for a controlled time under a set product pressure, delivering a volume determined by the time and pressure — simpler, less accurate for viscous products but well-suited to thin liquids). For ready meal tray filling, multi-nozzle piston or pump depositors fill multiple trays simultaneously for high throughput.
