It is one of a series of standards, which have been prepared for machines and equipment for meat processing in
accordance with EN 1672-2 and annex C.
Annexes A, B and C are normative parts.
This European Standard also contains a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

0 Introduction
This standard covers
mincing machines used in shops and preparation rooms,
mincing machines used in kitchens where sausages are prepared,
mincing machines used industrially,
and accessories.
The extent to which hazards are covered is indicated in this standard. For other hazards which are not covered by
this standard, machinery should comply with EN 292 where applicable.
1 Scope
1.1 This European Standard specifies requirements for the design and manufacture of mincing machines
(see Figures 1 and 2) used in a stationary position.
The machines covered by this standard are used for size reduction of fresh or frozen meat, meat products and fish
by cutting in a set of cutting tools.
Mincing machines for domestic uses are not included in this standard. Filling mincers are covered by prEN 12463
"Food processing machinery - Filling machines and auxiliary machines - Safety and hygiene requirements".
This standard applies only to machines that are manufactured after the date of issue of this standard.
Mincing machines in connection with using a hold to run foot switch are not covered by this standard.
1.2 This standard covers the following types:
Mincing machine with tray, feed intake and pusher, diameter < 52 mm on feed intake (see Figure 5)
Mincing machine with tray, feed intake, restrictor plate and pusher, diameter > 52 mm on feed intake
(see Figure 6)
1)
Mincing machine with feed intake hopper and cover, screw conveyor, with or without mixing screw in
feed intake hopper (see Figure 7)
)
Mincing machine with feed intake hopper, with or without cover, screw conveyor, with or without mixing
screw in feed intake hopper, with loading device (continuously or discontinuously)
Mincing machines comprise a machine base, a worm casing with a worm, a feed intake tray or hopper, a screw
conveyor (and sometimes an additional mixing screw in the feed intake hopper), 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.
)
In this case, the draft standard prEN 13570 „Food processing machinery - Mixers and mixing machines - Safety and hygiene
requirements“ should be taken into consideration

tray and restrictor plate machine with feed intake hopper, cover
and screw conveyor
Mincing 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.
1.3 Intended use
The fresh or frozen meat, meat product or the fish is fed manually or by means of the loading device into the
mincing machine. The product is fed to the worm either by means of a pusher or a screw conveyor and size
reduced in the set of cutting tools.
It is not intended that mincing machines are cleaned with pressurized water. However, it is to be foreseen that it is
difficult to guarantee that this method will never be used in practice. In order to deal with this eventuality, the
requirements of 5.3.3.2 should apply.
Intended use is defined in 3.12 of EN 292-1:1991.
