Foreword
This European Standard (EN 13570:2005) has been prepared by Technical Committee CEN/TC 153 “Food
processing machinery – Safety and hygiene specifications”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by November 2005, and conflicting national standards shall be withdrawn
at the latest by November 2005.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 98/37.
For relationship with EU Directive98/37, see informative Annex ZA, which is an integral part of this document.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
This European Standard is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for machines
that have been designed and built according to the provisions of this type C standard.
1 Scope
1.1 This European Standard specifies safety and hygiene requirements to minimise the hazards which can
arise during the commissioning, the use and the maintenance of mixing machines and their accessories
intended to be used in sausage kitchens and industrial operations.
This European Standard deals with all significant hazards, hazardous situations and events relevant to mixing
machines, when they are used as intended and under the conditions foreseen by the manufacturer ( see
Clause 4).
This European standard is not applicable to mixing machines which are manufactured before the date of
publication of this European Standard by CEN.
1.2 This European Standard covers the following types of mixing machines:
 Mixing machines with a tilting container, one or several mixing shafts
 Mixing machines with a stationary mixing container, front face or bottom discharge opening
 Mixing machines with a container and loading device
 Mixing machines with a container, mixing shaft(s), screw conveyor and loading device
The mixing machines are constructed of a machine frame, a trough-shaped mixing container, one or several
mixing shafts, an associated drive and electrical, hydraulic and pneumatic components, depending on
machine type.
The mixing shaft can be equipped with wings, screws, rods, paddles or the like.
Mixing machines may be equipped e. g. with
 cover over the top of the mixing container,
 pipe connections for gases, steam, water or vacuum,
 protective hood over the front face discharge opening,
 lifting devices for mixing shaft,
 loading device,
 screw conveyor at the discharge opening.

1.3 Intended use
The fresh or frozen meat, meat product, meat pieces or fish, salt, spices and other additives are loaded into
the mixing container by hand or by means of a loading device and mixed by the mixing unit.
The discharge outlet may be located at the bottom or the front face and can either be a slide, a flap, a pipe, a
pump or a screw.
During the production of this standard the following assumptions were made:
 Mixing machines are installed at a sufficiently lighted place.
 They are used only by designated and skilled operators.
Although it should be advised against, the standard, taking into account practice, deals with the hazards due
to cleaning with pressurised water.
