This document (EN 12331:2015) has been prepared by Technical Committee CEN/TC 153 “Machinery intended for use with
5、foodstuffs and feed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-18-02 AA Fleischverarbeitungs-maschinen of Section Nahrungsmittel- und Verpackungs
6、maschinen. Representatives of manufacturers and users of food processing machinery, and of the employers liability insurance associations contributed to this standard. This standard contains specifications giving detail to the essential requirements set out in Annex I of the “Machinery Directive”, D
7、irective 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Un
8、ion, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the
9、corresponding DIN EN or DIN EN ISO Standards with the same number. Where the International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available. Amendments This standard differs from DIN EN 12331:2011-02 as follows: a) some figures have
10、 been renewed and renumbered; b) Clause 2: EN 1088 has been replaced by EN ISO 14119; c) Clause 3: some definitions have been clarified and are used in this document; d) Clause 4: the information has been transferred to a table; e) Subclause 5.2.5.1: a note has been included stating that under certa
11、in conditions the combination of specific hole plates diameters with specific hole diameters represents an acceptable solution; f) Bibliography: with respect to Subclause 5.2.4.2, the standards DIN 9810 and UNI 11303 have been added.

DIN EN 12331:2015-12 EN 12331:2015 (E) 5 Introduction This document is a type-C-standard as stated in EN ISO 12100. The machinery concerned
33、and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. 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 ove
34、r the provisions of the other standards, for machines that have been designed and built according to the provisions of this type-C-standard. DIN EN 12331:2015-12 EN 12331:2015 (E) 6 1 Scope 1.1 This European Standard specifies requirements for the design and manufacture of mincing machines (see Figu
35、res 1a and 1b) used in a stationary position. The machines covered by this European Standard are used for size reduction of fresh or frozen meat, meat products and fish (hereinafter referred to as product) by cutting in a set of cutting tools. Mincing machines for domestic uses are not included in t
36、his European Standard. Filling mincers are covered by EN 12463 “Food processing machinery Filling machines and auxiliary machines Safety and hygiene requirements”. This European Standard applies only to machines that are manufactured after the date of issue of this European Standard. Mincing machine
37、s in connection with using a hold-to-run foot switch are not covered by this European Standard. This European Standard covers: mincing machines used in shops and preparation rooms; mincing machines used in kitchens where sausages are prepared; mincing machines used industrially; accessories. The ext
38、ent to which hazards are covered, is indicated in this European Standard. For other hazards which are not covered by this European Standard, machinery should comply with EN ISO 12100:2010 where applicable. This European Standard is not dealing with specific requirements for the control of mincing ma
39、chines with foot switch. 1.2 This European Standard covers the following types: mincing machine with feed tray, feed intake and pusher, diameter 52 mm on feed intake (see Figure 3); mincing machine with feed tray, feed intake, restrictor plate and pusher, diameter 52 mm on feed intake (see Figure 4)
40、; mincing machine with feed intake hopper and cover, screw conveyor, with 1)or without mixing screw in feed intake hopper (see Figure 5); mincing machine with feed intake hopper, with or without cover, screw conveyor, with1)or without mixing screw in the feed intake hopper, with loading device (cont
41、inuously or discontinuously). Mincing machines comprise a machine base, a worm casing with a worm, a feed tray (with feed intake) or a feed intake 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 dr
42、ive motor and depending on machine type electrical, hydraulic and pneumatic components. They will also have various safeguarding devices as examples in Clause 5. 1) In this case, EN 13570 should be taken into consideration.

45、sport carriage for the lock nut, the set of cutting tools, the worm and the screw conveyor, a lifting device for the lock nut, the set of cutting tools, the worm and the screw conveyor, a loading device. 1.3 Intended use The product is fed manually or by means of the loading device into the mincing
46、machine. The product is fed to the worm either by means of a pusher or a screw conveyor and size reduced in the set of cutting tools. It is not intended that mincing machines are cleaned with pressurized water. However, it is to be foreseen that it is difficult to guarantee that this method will nev
47、er be used in practice. In order to deal with this eventuality, the requirements of 5.3.4 should apply. DIN EN 12331:2015-12 EN 12331:2015 (E) 8 This European Standard specifies all significant hazards, hazardous situations and events relevant to mincing machines, when they are used as intended and
48、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. 2 Normative references The following documents,
