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. 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) - Mincing machine with feed intake hopper and cover, screw conveyor, with1) or without mixing screw in feed intake hopper (see Figure 7) - Mincing machine with feed intake hopper, with or without cover, screw conveyor, with1) 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.
