23、n This standard covers rotating bowl cutters with optional loading and unloading devices. !This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this d
24、ocument. 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 t
25、ype C standard.“ BS EN 12855:2003+A1:2010EN 12855:2003+A1:2010 (E) 5 1 Scope 1.1 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, mea
26、t 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 an
27、d 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 bo
28、wl cutters. 1.2 This standard only applies to machines which are manufactured after the date of issue of this standard. 1.3 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 1 200 mm or V 120 l For type 2 and t
29、ype 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 pneuma
30、tic 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. BS EN 12855:2003+A1:2010EN 12855:2003+A1:2010 (E) 6 Key 1 2 3 4 5 noise cover blade cov

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 s
33、team is added, or when boiling takes place at the same time. Bowl cutters do not operate in a continuous mode.
