1.1 This documentd specifies requirements for the design and manufacture of mincing machines (see Figures 1 a and 1 b).

The mincing machines (hereinafter referred to as machine) covered by this document are used for size reduction of fresh or frozen meat, meat products and fish (hereinafter referred to as product) by cutting in a set of cutting tools.

Machines for domestic uses are not included in this document. Filling mincers are covered by EN 12463 "Food processing machinery — Filling machines and auxiliary machines — Safety and hygiene requirements".

This document applies only to machines that are manufactured after the date of issue of this document.

This document covers:

— professional machines used for on-demand preparation in shops characterized by:

— designed as a table top machine;

— and having a feed tray;

— and the product is only feed manually;

— and is only operated from the ground;

— and is operated by no more than one operator;

— and with full visibility and full accessibility of the entire machine from the operator workstation;

— and having hole plate diameter ≤ 106 mm;

— and a worm casing set which is removable without using any tools;

— and the weight of the worm casing set ≤ 15 kg;

NOTE The table top machine can be equipped with a frame or base, so no separate table is needed.

— industrial machines used for industrial mass production, and which cannot be characterized as a professional machine.

The extent to which hazards are covered, is indicated in this document. For other hazards which are not covered by this document, machinery should comply with EN ISO 12100:2010 where applicable.

This document does not describe the specific requirements for the control of machines with foot switch.

This document does not describe the specific requirements for additional mixing screws in the feed intake hopper which are covered by EN 13570 "Food processing machinery — Mixing machines — Safety and hygiene requirements".

1.2 This document covers the following types of machines:

— machine with feed tray, feed intake and pusher (see Figure 3);

— machine with feed tray, feed intake, restrictor plate and pusher (see Figure 4);

— machine with feed intake hopper, cover and screw conveyor (see Figure 5);

— machine with feed intake hopper, with or without cover, screw conveyor, with loading device (continuously or discontinuously).

Machines comprise a machine base, a worm casing with a worm, a feed tray (with feed intake) or a feed intake hopper, a screw conveyor, a set of cutting tools, a lock nut, a loading device, a drive motor and – depending on machine type – electrical, hydraulic and pneumatic components. They will also have various safeguarding devices as examples in Clause 5.

Machines may be equipped e.g. with:

— an extraction claw;

— an ejector or extractor;

— a protective hood over the discharge outlet;

— a cover over the inlet opening of the feed intake hopper;

— a transport carriage for the lock nut, the set of cutting tools, the worm and the screw conveyor;

— a lifting device for the lock nut, the set of cutting tools, the worm and the screw conveyor;

— a loading device.

1.1 General

This document applies to:

— filling machines with cylinder and piston;

— filling machines with feed intake hopper;

— filling machines with vacuum hopper;

hereafter referred to as filling machines which process e.g. meat, cheese and other pasty substances, excluding dry or frozen materials. They pump foodstuff into casings or bring it to a following process.

This document applies also to the interchangeable equipment for filling machines with which a wide range of additional functions can be implemented. For example: portioning, depositing, mincing, co-extruding, dividing and forming.

This document deals with all significant hazards, hazardous situations and events relevant to filling machines and interchangeable equipment (hereafter referred to as machines), when they are used as intended and under the conditions foreseen by the manufacturer and also the reasonable foreseeable misuse (see Clause 4).

These significant hazards, hazardous situations and events can arise during all the life phases including transportation, assembly, dismantling, disabling and scrapping of the machines.

This document is not applicable to machines which were manufactured before the date of publication of this document by CEN.

Filling machines described in this document are no forming, filling and sealing machines as described in EN 415-3:1999+A1:2009. Clipping machines as described in EN 13885:2005+A1:2010 are not covered by this document.

1.2 Types of filling machines and interchangeable equipment covered by this standard

1.2.1 Filling machines with cylinder and piston

Filling machines with cylinder and piston consist of piston, closing cover, machine frame, accessory drive mechanism and electrical and hydraulic components (see Figure 1).

The material being processed will be fed by hand into the cylinder.

Filling machines with cylinder and piston can be fitted with a dividing device.

1.2.2 Filling machines with feed intake hopper

Filling machines with feed intake hopper (with or without infeed auger, see Figure 2) consist of feeder on the discharge side of the feed intake hopper, machine frame, drive mechanism for interchangeable equipment and electric, electronic or pneumatic components, depending on machine type.

The material being processed will be fed by hand (or optionally a loading device) into the feeding hopper of the filling machine.

Filling machines with feed intake hopper can be equipped with:

— dividing device;

— cover or photoelectric guard at the mouth of the feed intake hopper;

— pressure-sensitive protective device at the hopper edge;

— divided hopper;

— infeed auger;

— counter auger;

— step or ladder;

— two-hand control device at the mouth of the feed intake hopper;

— knee-operated lever switches or hand operated switches.

1.2.3 Filling machines with vacuum hopper

Filling machines with vacuum hopper (with or without infeed auger, see Figure 3) consist of suction pipe with storage container, feeder, vacuum hopper with locking device on the intake side, machine frame, drives for interchangeable equipment and electrical, electronic or pneumatic components, depending on the machinery category.

Filling machines with vacuum hoppers can be loaded by one or more of the following:

— manual loading;

— vacuum suction;

— feeder.

Filling machines with vacuum hoppers are to be switched on and off by lever switches operated by knee or hand and/or by remote control signals.

Filling machines with vacuum hoppers can be equipped with:

— dividing device;

— cover on vacuum hopper;

— infeed auger;

— counter auger;

— foot board or ladder;

— suction pipe and storage container.

1.2.4 Interchangeable equipment for filling machines

Interchangeable equipment are devices which can be assembled to filling machinery by the operator in order to attribute one or more new functions such as: portioning, twisting, voiding, forming, mincing. Interchangeable equipment does not operate independently. The interchangeable equipment will be actuated directly or by filling machines.
