Raque Depositor Piston Filler

• Filling pies, tarts, and pastries with fruit fillings, jams, or creams.
• Depositing sauces, gravies, and purees into ready meal trays or pouches.
• Handling chunky products such as stews, curries, or fruit preparations.
• Portioning viscous batters and doughs for bakery products.
• Dispensing condiments and spreads in food service or production environments.

Typical capacity

Throughput for this class of equipment can vary significantly, often ranging from hundreds to several thousand deposits per hour, depending on product viscosity and deposit volume.

Power supply

Pneumatically operated units typically require a compressed air supply, commonly 6-8 bar, with electrical power (e.g., 230V single-phase) often needed for control systems.

Deposit volume range

Piston fillers of this type are commonly capable of depositing volumes from a few millilitres up to several litres per cycle, adjustable via piston stroke.

Product viscosity suitability

Designed for a wide range of viscosities, from thin sauces to thick pastes and chunky products, due to the positive displacement action of the piston.

Outlet pipe diameter

A 2-inch outlet pipe, as mentioned, is suitable for high-volume dispensing and handling products with larger particulates.

Materials of construction

Components in contact with product are typically made from food-grade stainless steel (e.g., 304 or 316) for hygiene and durability.

• What maintenance is typically required for a piston depositor?

  Routine cleaning of product contact parts is essential. Periodic inspection and replacement of seals, O-rings, and other wear parts are also common to ensure optimal performance and prevent leaks.

• Can this type of depositor handle hot products?

• Is changeover between different products or deposit volumes straightforward?

• What safety features are commonly found on these machines?

• What kind of spare parts are usually needed?

Food depositors are valued for their precision, consistency and reliability in portioning applications across bakery, confectionery and prepared foods sectors. Buyers typically prioritise machines with minimal wear, clear maintenance histories and compatible control systems. Key strengths include durability when properly serviced, adaptability to various product viscosities, and straightforward operation. When purchasing used equipment, inspecting nozzles, pumps and pneumatic components is essential, as wear directly affects deposit accuracy. Machines from reputable manufacturers with documented service records generally command buyer confidence and deliver strong long-term value.
