Figure 1 — Piston depositor 1.2.3 Chamber depositor A chamber depositor comprises a hopper feeding one or more product measuring chambers that are filled under gravity from the top. When the chamber has been filled with product the flow of product is stopped either by moving the chamber or using a product cutting device. The chamber is then discharged through the bottom of the chamber either by moving the chamber or by moving a plate in the base of the chamber. The volume of product dispensed is varied by altering the volume of the chamber. Chamber depositors are typically used to deposit free-flowing products like cooked rice or pasta. Figure 2 shows the typical cross section of a chamber depositor.

Figure 3 — Roller depositor 1.2.5 Pump depositor A pump depositor comprises a hopper that feeds a pump which in turn feeds pipe-work on which are mounted one or more product dispensing valves. The dispensing valves may remain fixed, move up and down or from side to side in synchronization with a product conveyor. The volume of product dispensed is varied by altering the length of time that the dispensing valves are open. Pump depositors are typically used to deposit liquids or liquids containing finely divided solids Figure 4 shows the typical cross section of a pump depositor.

Figure 6 — Food depositor equipped with wheels 4.2.14 Slip, trip and fall hazards resulting from the design of the machine Slip accidents can occur if the product being deposited or cleaning media is spilt on the floor. Trip accidents may occur if power cables or compressed air pipes powering the food depositor are left on the floor. Falls may occur if people stand on parts of the depositor e.g. for hopper loading, size changing, maintenance or cleaning. 4.2.15 Hygienic design hazards The product being deposited can become contaminated, e.g. by the following causes: — incorrect choice of contact materials; — inappropriate construction methods; — non-food grade lubricants which are allowed to come into contact with the product, e.g. from gearboxes or compressed air exhausts. 4.3 Hazards associated with a piston depositor 4.3.1 General The hazards described in 4.2 and those detailed below are specifically associated with a piston depositor. Figure 7 illustrates the components that typically present hazards on piston depositors. SIST EN 15180:2015

Key 1 hopper 2 D-valve 3 product measuring chamber 4 measuring chamber drive mechanism 5 product dispensing valve Figure 7 — Typical components on a piston depositor 4.3.2 Hopper The product hopper will usually be mounted over product feeding devices that present crushing, shearing and drawing-in hazards and may be equipped with stirring devices that present entanglement hazards. On some machines the hopper is removed for cleaning and excessive effort may be required to remove or replace the hopper. Excessive effort and a risk of falling may occur if the hopper cannot easily be loaded with product from floor level. 4.3.3 D-valve The D-valve presents a shearing hazard if it can be reached when operating under power either during normal operation, trouble-shooting or cleaning, e.g. by partly dismantling the machine. 4.3.4 Product measuring chamber The product measuring chamber presents crushing and shearing hazards if it can be reached when operating under power either during normal operation, trouble-shooting or cleaning, e.g. by partly dismantling the machine. 4.3.5 Measuring chamber drive mechanism Measuring chamber drive mechanisms are typically pneumatic cylinders that can present crushing and shearing hazards. Other drive mechanisms, e.g. electric motors, driving rack and pinion mechanisms will present crushing and drawing-in hazards. SIST EN 15180:2015

These mechanisms present crushing and entanglement hazards. On some machines the flow of product into the chamber may be regulated by a product cutting device in the form of a brush or shear blade. These mechanisms present crushing and shearing hazards. 4.4.4 Product measuring chamber Product measuring chambers will typically incorporate a mechanism to vary the volume of the chamber and a discharging flap. These mechanisms present crushing and shearing hazards. On machines where the product measuring chamber moves there is a shearing hazard between the measuring chamber and fixed assemblies on the machine. 4.4.5 Container or materials handling mechanisms See 4.3.7.

The drive mechanism powering the rollers is also a drawing in hazard. The hopper and roller assembly may move backwards and forwards causing a crushing hazard between the assembly and the supporting frame. 4.5.4 Product extruding die Product extruding dies may be equipped with mechanisms to rotate the die as the product is extruded. These mechanisms can present crushing and drawing-in hazards. It is typical for the die assembly to be withdrawn SIST EN 15180:2015

However, most designs of pump present shearing or drawing-in hazards if the moving parts can be reached, e.g. by reaching into the hopper or by partly disassembling the pump. 4.6.3 Manifold Some pump depositors incorporate a manifold that supports several dispensing valves. The manifold may be fixed or attached to a mechanism that moves the manifold forwards and backwards and up and down in synchronization with the product conveyor. These mechanisms will normally present crushing hazards when they lower the valves and may also present crushing and shearing hazards when the mechanism moves up, forwards or backwards. If the product being filled is hot the manifold can become a burning hazard. 4.6.4 Product dispensing valves See 4.3.6. 4.6.5 Rise and fall mechanism See 4.5.6. 4.6.6 Container and materials handling equipment See 4.3.7.1.

The product measuring chamber presents a crushing hazard if it can be reached when operating under power either during normal operation, troubleshooting or cleaning, e.g. by partly dismantling the machine. 4.7.5 Measuring chamber drive mechanism See 4.3.5.
