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 conditions of misuse which are reasonably foreseeable 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,

 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

By using a hold-to-run control these distances are not required

5.2.7.3.3 Mast-type lift-tilt device

The danger points between the load bearing device and the mast on the side opposite the load bearing device shall be protected if the distance between the load bearing device and the mast is < 120 mm If the tilt range

of the load bearing device is > 2000 mm or more above the floor, no guarding is required if the distance between the load bearing device and the mast is > 60 mm

During the climb of the loading device the mixing shafts shall stand still

5.2.7.3.4 Lift-tilt device for feed heights > 2500 mm

The path of movement of the load bearing device, with the exception of the run-in and run-out opening, shall

be protected by means of a distance guard (e g a protective fence) An electrosensitive protective device (e g a light barrier, mechanical bar or flap) shall be fitted on the upper edge of the run-in and run-out opening

to prevent lifting of incorrectly positioned trolleys or containers (see figure 7)
