24、51:2005+A1:2010EN 12851:2005+A1:2010 (E) 4 Introduction The use of attachments involves various mechanical hazards and the attachments themselves need to meet food hygiene requirements. A catering attachment is a mechanical device which takes its motive power from a unit which is not part of the att
25、achment. Some attachments are dedicated to a particular motive power source from the same manufacturers; others are designed to be used on a range of machines and power units from any manufacturer. !Their extensive use in numerous countries justifies the need of a standard covering both safety and t
26、he hazards to food hygiene.“ This European Standard is a type C standard as stated in EN ISO 12100-1. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are differen
27、t 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.

28、 (E) 5 1 Scope 1.1 This European Standard specifies the safety and hygiene requirements for the design and manufacture of the following catering attachments intended to be connected to an auxiliary drive hub of machines used in catering (mainly but not exclusively planetary mixers) and to be used in
29、 the commercial and institutional catering industry: vegetable cutters and cheese graters; worm type attachments: fruit squeezers; meat mincers; pasta extruders; coffee grinder; strip cutters; planetary mixers and whippers; potato-mashers. 1.2 This European Standard deals with all significant hazard
30、s, hazardous situations and events relevant to catering attachments, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. It deals with the hazards due to the use, the maintenance, the cleaning, removal of jammed food, feeding and ch
31、anging the tool (see Clause 4). 1.3 This European Standard is not applicable to: catering attachments which are exclusively part of the equipment of the machines they are intended for (as optional or standard equipment); the driving machines for which the attachments are intended (but the standard d
32、eals with the interface of the attachments with these machines); attachments including electrical equipment. 1.4 Noise is not dealt with in this European Standard. 1.5 This European Standard is not applicable to catering attachments which are manufactured before the date of its publication as EN. 2

38、he hopper or other part of the attachment 3.1.2 plunger device device assisting feeding, which is removable 3.2 Description Attachments essentially consist of two parts: a) A part common to all attachments which includes: a device which engages on a drive shaft from the driving machine; devices for
39、fastening and positioning the attachment on the power drive machine either directly or via an adapter which allows the attachment to fit to other connecting systems (or to other machines). b) A part specific to the attachment which includes the tools. The main components of this part can be: 1) for
40、vegetable cutting attachments and cheese grater (see Figure 1): a housing (5) into which a cutting device is inserted, the cutting device can be a blade (9) with or without a grid (3); a cover (4) incorporating the product feed device which is fixed to the housing; a feed device which may be a feed
41、hopper (6) with pusher device (1) and/or plunger device (2); disc, cylinder or cone fitted with cutting/grating device of variable size (11) (the vegetable cutting attachment can be equipped with such tools), for cheese graters. Food product is loaded into the feed device and held against to the cut
42、ting device by manual pressure on the pusher or plunger. When the food is cut, it falls from the housing via the delivery chute (10) into a receptacle which is not part of the machine.
