5、ments. This standard has been prepared by Technical Committee CEN/TC 153 “Machinery intended for use with foodstuffs and feed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Worki
6、ng Committee NA 060-18-01 AA Bckereimaschinen of Section Nahrungsmittelmaschinen. Stakeholders were involved in the development of the standard. This standard contains specifications meeting the essential requirements set out in Annex I of the new “Machinery Directive”, Directive 2006/42/EC, and whi
7、ch 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 Union, it is deemed a “harmoni
8、zed” 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 corresponding DIN EN or DIN
9、EN ISO Standards with the same number. Amendments This standard differs from DIN EN 13389:2006-04 as follows: a) the standard has been brought in line with the new Machinery Directive 2006/42/EC; b) Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of

25、 4 Introduction This European Standard is a type C standard as stated in !EN ISO 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 fr
26、om 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.

27、1 Scope !This European Standard specifies requirements for the design, transport, installation, operation and maintenance of batch production fixed or tilting horizontal bowl type mixers with one or two rotating shafts with or without movable blades. These mixers are used to mix, knead and homogenis
28、e food for animal or human consumption in powder, paste or liquid form. The mixers can be floor mounted or transportable (with or without castors). They are intended to be used when stationary.“ These machines are used in feed mills and factories which produce, work on or process foodstuff, for exam
29、ple biscuits, bread, chocolate, cereal products. This European Standard does not deal with the use of the machine in potentially explosive atmospheres. !This European Standard deals with the significant hazards, hazardous situations and events relevant to mixers with horizontal shafts, when they are
30、 used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).“ This European Standard also specifies food hygiene requirements. The feeding equipment, the dosing equipment, and the requirements of equipment for the supply of inert gases, and fo
31、r heating and cooling, are excluded from the scope of this European Standard. The hazards due to the unloading equipment (container, discharge belt, etc.) are not dealt with in this European Standard. When drafting this European Standard, it has been assumed that the machines are not intended to be
32、cleaned with a water jet. This European Standard is not applicable to mixers with horizontal shafts which are manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensable for the application of this European

46、 range of machines covered by this European Standard are designed to batch mix powdered, paste and liquid products, the primary ingredient usually being flour. When the mixing bowl is in its loading position, the machine receives the dry or wet ingredients, weighted or metered. This operation is con
47、trolled by either the operator of the machine or automatically. The machine mixes and/or melts ingredients during a time or with an energy based measurement. When the mixing cycle is over, the product is unloaded into a mobile container, or into a fixed hopper or onto a discharge belt, e. g. by tilt
48、ing the mixing bowl. The machine may be manually operated or completely automatic. The bowl may be heated or cooled. 3.3 Description Typical mixers with horizontal shafts are shown in Figures 1a and 1b, with the following main elements: a) rigid machine frame; b) mixing bowl; c) rotating mixing shafts; d) main drive motor and gearbox; e) bowl tilting mechanism; f) electrical controls; g) delivery device:
