Introduction

Food depositors are used extensively in Europe, in commercial and industrial food preparation

applications. They present some health and safety hazards that have the potential to cause serious injury.

This document is a type-C standard as stated in EN ISO 12100.

This document is of relevance, in particular, for the following stakeholder groups representing the market

players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);

— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).

Others can be affected by the level of machinery safety achieved with the means of the document by the

above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);

— machine users/employees (e. g. trade unions, organizations for people with special needs);

— service providers, e. g. for maintenance (small, medium and large enterprises);

The above-mentioned stakeholder groups have been given the possibility to participate at the drafting

process of this document.

The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are

— food depositors that are powered exclusively by manual effort.
This document does not deal with the following hazards:

— hazards related to the use of food depositors in a potentially explosive atmosphere;

— hazards that may arise from using a food depositor to deposit a non-food product.

This document is not applicable to food depositors that were manufactured before the date of its

publication as a European Standard.
1.2 Types of food depositors
1.2.1 General

This document deals with five different types of food depositor. The component parts of each of the

different types of depositor are labelled in the figures shown in Clause 4 of this document.

1.2.2 Piston depositor

A piston depositor typically comprises a hopper, a rotary valve, a product measuring chamber in the form

of a piston and a product dispensing valve. Some piston depositors incorporate several product

measuring chambers and dispensing valves. Some designs dispense the product directly from the rotary

valve without the use of a separate product dispensing valve. The volume of product dispensed is varied

by altering the stroke of the product measuring chamber piston. Piston depositors are used to fill liquids,

liquids containing solids in suspension and pastes. The product dispensing valve may be attached rigidly

to the depositor or using a flexible pipe and in some cases is held by the operator. Figure 1 shows the

typical cross section of a piston depositor.

prEN 15180:2021 (E)
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 product 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.

oSIST prEN 15180:2021
prEN 15180:2021 (E)
1.2.4 Roller depositor

A roller depositor typically comprises a hopper that feeds product to two or more fluted contra-rotating

rollers. These rollers force the product through one or more dies that shape the product. The product is

then separated using a product cutting device like a wire cut mechanism. On some designs of the machine

the dies are moved while the product is dispensed to produce a shaped product. The volume of product

dispensed is varied by altering the timing of the product cut-off device. Roller depositors are typically

used to deposit dough or confectionery products. Figure 3 shows the typical cross section of a roller

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.

prEN 15180:2021 (E)
Figure 4 — Pump depositor
1.2.6 Screw depositor

A screw depositor comprises a hopper in which a screw is mounted. When the screw rotates it draws

product from the hopper into a pipe. The hopper may be equipped with stirrers to move the product

towards the screw and a product measuring chamber or product dispensing valve may be fitted to the

discharge of the screw. The volume of product can be varied by increasing or decreasing the speed of the

screw, by varying the volume of the measuring chamber or by controlling the actuation of the product

dispensing valve. Screw depositors are typically used to deposit dough, pastes or creams. Figure 5 shows

the typical cross section of a screw depositor.

4 Safety requirements
4.1 General

All the machines in the scope of this document shall comply with the safety requirements and protective

or risk reduction measures in 4.2 and the relevant machine specific measures in 4.3 to 4.7.

4.2 General requirements for food depositors
4.2.1 Introduction

The following requirements apply to all food depositors in the scope of this document where the

equivalent hazard exists.
4.2.2 Requirements to eliminate mechanical hazards
4.2.2.1 Safeguarding of moving parts
4.2.2.1.1 Safety by design

Moving parts can be considered to be safe by design provided the parts are smooth, the force exerted by

the moving parts does not exceed 75 N, the pressure they exert against the part of the body most likely

to be in contact with the mechanism is less than 25 N/cm and their energy is less than 4 J. If the

hazardous movement is automatically reversed within 1 s when resistance is detected, the movement

can be considered as safe provided the force does not exceed 150 N, the pressure does not exceed

50 N/cm and the energy is less than 10 J.

Some crushing hazards from moving parts can also be made safe by design by ensuring sufficient distance

between moving and fixed parts and between one moving part and another part using the dimensions

indicated in EN ISO 13854:2019.
4.2.2.1.2 Fixed and interlocked guards

Moving parts which cannot be made safe by design shall be safeguarded by fixed or interlocked enclosing

guards complying with EN ISO 14120:2015 and dimensioned using EN ISO 13857:2019, Table 3, Table 4

and Table 6. Where distance guards are used they shall be dimensioned and positioned in accordance

with EN ISO 13857:2019, Table 2, but shall be at least 1 600 mm high. Where it is foreseeable that

someone will try to put their feet into a machine, e.g. because it is next to an access platform, guards shall

be dimensioned and positioned in accordance with EN ISO 13857:2019, Table 7, and any other relevant

tables of EN ISO 13857:2019.
4.2.2.1.3 Openings in guards

Openings in guards shall be positioned or dimensioned to prevent access to hazard zones within the

machine when standing on the floor or access level and reaching into the opening.

The minimum reach distance to the nearest hazard zone through the opening shall comply with

EN ISO 13857:2019, Table 3, Table 4, and Table 6.
4.2.2.1.4 Interlocking devices associated with guards

Moveable guards shall be interlocked with devices that comply with EN ISO 14119:2013, 4.2 and 4.3. The

requirements of EN ISO 14119:2013, Clauses 5, 7 and 8, shall be satisfied.

The design of the control system shall ensure that hazardous mechanisms, that can be reached by the

operator shall stop within 1,0 s of an interlocking guard without guard locking being opened. Where this

cannot be achieved, the guard shall be fitted with a guard locking device that prevents the guard from

being opened until the hazardous movement has stopped.

oSIST prEN 15180:2021
prEN 15180:2021 (E)

If the hazardous moving parts directly involved in the process cannot be stopped within 1,0 s, the relevant

interlocking guards shall be equipped with guard locking as defined in EN ISO 14119:2013, 3.4, and

complying with EN ISO 14119:2013, 4.3 and 5.7.
