Overview
EN 13570:2005+A1:2010 - "Food processing machinery - Mixing machines - Safety and hygiene requirements" is a CEN Type C standard that defines safety and hygiene requirements for mixing machines used in sausage kitchens and industrial food operations. It covers machines manufactured after the date of publication and addresses hazards during commissioning, normal use and reasonably foreseeable misuse. The standard also includes Amendment 1 (2010) and an informative Annex ZA linking the standard to EU Directive 2006/42/EC.
Key topics and technical requirements
- Machine types covered: tilting containers, stationary containers with front-face or bottom discharge, machines with loading devices, and machines with mixing shafts plus screw conveyors.
- Components addressed: trough-shaped mixing containers, mixing shafts (wings, paddles, screws), drive systems, electrical/hydraulic/pneumatic components, covers, protective hoods, loading devices and screw conveyors.
- Hazard identification: zones and significant hazards (entanglement, shearing, severing, crushing, drawing-in, impact, electrical and hydraulic risks, loss of stability).
- Safety measures: requirements for guards, interlocking devices, protective hoods, mechanical trip bars, interlocked steps and safety devices for container position; design and verification of protective measures are required.
- Hygiene and cleanability: normative guidance (Annex B) on design principles to ensure surfaces, joints and geometry support effective cleaning and prevent contamination.
- Verification and testing: procedures for verifying safety and hygiene measures (including a noise test code in Annex A) and requirements for information for use (instructions, maintenance and risk assessment).
- Risk assessment: conformity requires a risk assessment per EN ISO 14121-1 / EN ISO 12100 to identify all relevant hazards and validate protective measures.
Practical applications
- For machine manufacturers: use EN 13570 to design mixing machines that meet European safety and hygiene expectations for meat and fish processing, and to demonstrate conformity with essential requirements of the Machinery Directive.
- For food processors and plant engineers: apply the standard to select, commission and maintain mixers safely, specifying hygienic construction, guarding and access controls.
- For safety engineers, compliance officers and certifiers: use the standard to evaluate guarding, control systems, electrical safety and cleaning design during conformity assessment and audits.
- For maintenance teams and operators: the standard defines safe maintenance practices, protective devices and operational precautions, including foreseeable misuse scenarios (e.g., cleaning with pressurised water).

The outside walls shall be designed (e. g. vertical and smooth) to prevent the operator climbing on the machine. This also applies to interlocked steps in their folded position. a) Interlocked step If danger points in the feed intake hopper can be reached from steps or platforms (design measure < 2250 mm). the steps or treads of platforms shall be foldable and interlocked for preventing the functioning of the machine when they are in their protective position. When the mixing machine is running without product, the mixing shaft shall come to a standstill within 2 s after the interlocking system has been actuated by moving the step into its protective position.

If the standing area is < 500 mm above ground, an area of a width ≥ 400 mm and a length ≥ 350 mm is sufficient. The standing area shall be of the non-slip type. Platforms and accessible areas shall have of a width B ≥ 500 mm. The length of the platform shall correspond to the length of the hopper. Platforms which are located > 500 mm above ground shall be fitted with safety devices to prevent falls. Intermediate steps, stairs or ladders and grab handles shall be provided if the step-up height to the step or to the platform is > 500 mm. The standing areas and treads shall be sufficiently large and of the non-slip type and arranged at identical distances from one another. The standing area of the intermediate step shall have a width of ≥ 300 mm and a length of ≥ 200 mm. Treads of ladders shall have a length of ≥ 500 mm and a width of ≥ 80 mm.

5.2.4 Discharge outlet on mixing machines with front face or bottom discharge outlet Zone 2 Access to the danger points on the mixing shaft behind the discharge outlet shall be protected. This shall be achieved by one of the following measures: On mixing machines, the discharge outlet shall be protected by the use of a guard (e. g. protective hood). The guard shall project ≥ 550 mm in the operating direction and be provided with a lateral projection. The distance between the trolley or container and the protective hood shall be ≤ 50 mm (see figure 6). The lateral access shall be prevented. The mixing shaft shall come to a standstill at < 2 s, or the discharge flaps shall be closed within < 2 s, after the protective hood or the trolley or the container has been moved 50 mm out of the protective position. When using grill-shaped protective hoods or protective hoods of a rod-shaped material, the safety distances shall comply with !EN ISO 14121-1:2007, Table 4". The protective hood or the discharge flaps shall be interlocked with the functioning of the machine. For requirements relating to the interlocking system of the movable protective hood, see the introductory requirements of 5.2. SIST EN 13570:2005+A1:2010
use of a hold to-run control for the lowering of the load bearing parts, use of gravity only for lowering the lifting device, a special device on the machine or lift-tilt device so that powered descent of the load-bearing device onto an obstruction cannot cause instability. This can be e. g. a level switch, to automatically stop the descent. Where the machine or the lift tilt device is fixed to the floor, overload conditions to the load bearing components of the lift tilt device shall be prevented in the event of the power operated loading device meeting an obstruction. This can be achieved e. g. by a slipping clutch or overload cut out to automatically stop the lowering motion. 5.2.7.3.2 Lifting device 5.2.7.3.2.1 Lifting devices shall be designed to prevent trolleys or containers from falling off. This can be achieved by a fixing device at the loading device for trolleys and containers 5.2.7.3.2.2 Lifting devices shall be designed that trolleys or containers do not create danger points during up and down movements. This can be achieved by the observance of all following measures: distance between the loading device, trolley and the machine base shall be > 120 mm, distance between the trolley or loading device and the feed intake hopper edge > 25 mm.
