The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the

25、 scope of this European Standard. 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

26、 the provisions of this type C standard. BS EN 454:2014EN 454:2014 (E) 6 1 Scope 1.1 This European Standard specifies safety and hygiene requirements for the design and manufacture of fixed bowl planetary mixers with a tool having a planetary movement by using two parallel axes. The capacity of the

27、bowl is greater than or equal to 5 L1)and less than or equal to 200 L. These planetary mixers are used separately in the food industry and shops (catering, bakery, pizza, pastry and confectionary industry) for mixing, kneading and emulsifying/whipping food products (e.g. cocoa, flour, sugar, oils an

28、d fat, eggs, and other ingredients). These machines are fed by hand and sometimes during operation without stopping the machine. Processing is carried out in cycles of variable duration. It can be either manually or automatically controlled, in individual cycles or on a cycle repeat basis, etc. This

29、 European Standard deals with all significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, disassembling and scrapping of planetary mixers, when they are used as intended and under the conditions of misus

30、e which are reasonably foreseeable by the manufacturer(see Clause 4). 1.2 This European Standard does not deal with the following machines: catering attachment for planetary mixers (see EN 12851); continuously fed machines; dough mixers (see EN 453); whipping mixers which contain no parallel axes; s

31、tirring machines; experimental and testing machines under development by the manufacturers; machines used in other industry, for example: meat industry, candy industry, pharmaceutical industry, chemical industry; domestic appliances. 1.3 This European Standard is not applicable to machines which are

32、 manufactured before its date of publication as a European standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

42、which is used for mixing, kneading and emulsifying Note 1 to entry: The tool can have different shapes. BS EN 454:2014EN 454:2014 (E) 8 Note 2 to entry: The scraper is considered as a tool in this document. 3.1.2 planetary movement rotation of a tool both on itself and around the inside of a bowl by

43、 using two parallel axes 3.1.3 working position stable position both for the bowl and the tool and in which the bowl is locked in the upper position and the tool, locked on its shaft, is nearest to the bottom of the inside of the bowl 3.2 Description A planetary mixer (see Figure 1) usually consists

44、 of a frame supporting: a casing (1), containing the tool(s) drive mechanism; control devices (2); a bowl (3) equipped with a grid or a solid cover, in which ingredients are processed; interchangeable tool (4) designed to process ingredients; their rotation speed may be either constant or variable;

45、an optional auxiliary drive hub (5) for catering attachments (see EN 12851); a device (6) for vertically moving the bowl or the head of the mixer to allow tool removal, or tilting of the head to remove the tool; a device (7) for handling the bowl (optional), for example a trolley; an interlocked gua

46、rd (8); bowl heating device (optional, not included in Figure 1); bowl cooling device (optional, not included in Figure 1); bowl gravity discharge (optional, not included in Figure 1).

47、ey 8 interlocked guard (solid cover) Figure 1 Main parts of a planetary mixer 3.3 Classification Planetary mixers are classified into the following two categories according to their bowl volume: class 1: bowls having a volume equal to or greater than 5 L and less than 10 L; class 2: bowls having a v

48、olume equal to or greater than 10 L and less than or equal to 200 L, where the bowl volume is the maximum volume of water in litres that the bowl can contain. When a mixer is supplied with several bowls of different capacities, the mixer classification is determined by the size of the bowl with the

49、greatest volume. 4 List of significant hazards This clause contains all the significant hazards, hazardous situations and events, identified by risk assessment as significant for this type of machinery and which require measures to eliminate or reduce the risk associated with the identified hazards (see Table 1).
