Food processing machinery - Rotating bowl cutters - Safety and hygiene requirements
|Publication Date:||1 August 2003|

This European Standard specifies requirements for bowl cutters (see figure 1) used when stationary and positioned on the floor or at table height.
Bowl cutters are food machines used to process fresh or frozen meat, meat products, fish and vegetables in a rotating bowl. This is performed by means of vertical blades rotating around a nearly horizontal axis.This European Standard deals with all significant hazards, hazardous situations and events relevant to rotating bowl cutters, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This European Standard specifies the hazards which can arise during commissioning, operation, cleaning, use, maintenance and decommissioning of the machine.
This standard does not apply to household bowl cutters.
This standard only applies to machines which are manufactured after the date of issue of this standard.
This standard covers the following types of bowl cutters according to the diameter (D) or the volume (V) of the bowl:
- Type 1 bowl cutters
D < 700 mm or 2 l < V < 30 l
- Type 2 bowl cutters
700 mm < D < 1 200 mm or 30 l < V < 120 l
- Type 3 bowl cutters
D > 1 200 mm or V > 120 l
For type 2 and type 3 bowl cutters, loading devices are also covered in this standard.
Bowl cutters are constructed, for example, from a machine frame, a bowl, a set of cutting blades, a blade shaft, a blade cover, a noise cover, a loading and removal device, an associated drive and electrical, hydraulic and pneumatic components and also components for fumigating, vacuuming, heating and cooling according to machine type.
NOTE In preparing this standard it was assumed that the machine would be operated by trained personnel.
The fresh or deep-frozen material is fed manually or by means of a loading device into the bowl of the bowl cutter. On account of the rotation of the cutter bowl at different speeds of the blade shaft, the material is mixed with additives, size reduced or emulsified. This can also take place under vacuum, or when liquid nitrogen or carbon dioxide or steam is added, or when boiling takes place at the same time.
Bowl cutters do not operate in a continuous mode.
