4、 authoritative.Document comprises 47 pages03.15 DIN EN 453:2015-04 2 A comma is used as the decimal marker. National foreword This standard includes safety requirements. This document (EN 453:2014) has been prepared by Technical Committee CEN/TC 153 “Machinery intended for use with foodstuffs and fe
5、ed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-18-01 AA Bckereimaschinen of Section Nahrungsmittel- und Verpackungsmaschinen. Representatives
6、of manufacturers and users of bakery equipment, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machi
7、nes 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 Union, it is deemed a “harmonized” standard and
8、 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 corresponding DIN EN or DIN EN ISO Standards
9、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 453:2010-10 as follows: a) normative references have been updated; b) a solid guard to prot
10、ect against dust emission has been added; c) the table concerning the verification of safety and hygiene requirements has been completely revised. Compared with DIN EN 453:2015-01, the following corrections have been made to the German version only and therefore do not affect the English text: a) Fo
11、reword, paragraph 5: EU-Richtlinien has been replaced by EU-Richtlinie 2006/42/EG (EU Directive 2006/42/EC); b) Foreword, paragraph 6: EU-Richtlinien has been replaced by EU-Richtlinie 2006/42/EG (EU Directive 2006/42/EC); c) Subclause 7.2 e) 1) and 4): unter Druck stehendem Wasser has been replaced
12、 by Druckluft (pressurized air).

DIN EN 453:2015-04EN 453:2014 (E) 5 Introduction This document is a type C standard as stated in EN ISO
32、12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the 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
33、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. DIN EN 453:2015-04EN 453:2014 (E) 6 1 Scope 1.1 This European Standard specifies safety and hygiene requirements for the design and
34、 manufacture of dough mixers with rotating bowls of capacity greater than or equal to 5 L1)and less than or equal to 500 L. These dough mixers are used separately or in a line in the food industry and shops (pastry-making, bakeries, confectionery, etc.) for manufacturing of dough by mixing flour, wa
35、ter and other ingredients. These machines can be fed by hand or mechanically. These machines are sometimes used in other industries (e.g. pharmaceutical industry, chemical industry, printing), but hazards related to these uses are not dealt with in this standard. This European Standard deals with al
36、l significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, disassembling and scrapping of dough mixers, when they are used as intended and under the conditions of misuse which are reasonably foreseeable b
37、y the manufacturer (see Clause 4). 1.2 This European Standard does not deal with the following machines: planetary mixers (see EN 454); continuously fed machines; mixers with stationary vertical bowls; experimental and testing machines under development by the manufacturer; domestic appliances; auto
38、matic loading and unloading devices. 1.3 This European Standard is not applicable to machines which are 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 indispe

48、a bowl to contain the ingredients to be mixed. This bowl is driven either mechanically or through the action of the kneading tool on the dough, may be removable, and may tilt; one or more kneading tools on a vertical or inclined fixed axis or two special arms mixing the dough. In some cases these de
49、vices can be raised to allow bowl or food removal.
