28、 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 document. When provisions of this type C standard are different from those which are stated in type A or B standa
29、rds, 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. BS EN 13591:2005+A1:2009EN 13591:2005+A1:2009 (E) 6 1 Scope This European Standard applies to th
30、e design and manufacture of fixed deck oven loaders used in the food industry, bakeries, pastry-making, etc. These machines are used to place dough pieces on each deck of fixed deck ovens and to remove the baked products from each deck. This equipment may be: manual; semi-automatic (some movements p
31、owered, some movements requiring manual power). The European Standard covers technical safety and hygiene requirements for the design, installation, adjustment, operating, cleaning and maintenance of this equipment. !This European Standard deals with the significant hazards, hazardous situations and
32、 events relevant to fixed oven deck loaders, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).“ Noise from fixed deck oven loaders is not considered to be a significant hazard. That does not mean that the manufacturer o
33、f the machine is absolved from reducing noise and making a noise declaration. Therefore a noise test code is given in Annex A. The following equipment are excluded: experimental equipment and equipment under development by the manufacturer; loaders for conveyor ovens; loaders integral to the oven; f
34、ully automated fixed deck oven loaders. This European Standard in not applicable to fixed deck oven loaders that 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 d

43、ion 3.1 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN ISO 12100-1:2003 and the following apply. NOTE Shifting, lifting, and loading in the oven are the three main functions of a fixed deck oven loader. 3.1.1 shifting movement of the whole ove
44、n loader to the oven face 3.1.2 lifting vertical movement up and down 3.1.3 loading action of placing pieces of dough on the oven loader BS EN 13591:2005+A1:2009EN 13591:2005+A1:2009 (E) 8 3.1.4 loading in the oven action of introducing and placing pieces of dough on the decks of the oven 3.1.5 unlo
45、ading action of removing loaves from the oven deck once baking has finished 3.1.6 nominal mass of dough the mass the loader is intended for 3.2 General principle A fixed deck oven loader generally consists of a frame mounted on castors supporting a lifting device and a supporting platform with the l
46、oading device (see Figure 1). The frame is mounted on castors to enable the loader to be positioned in front of the oven for loading and unloading. The lifting device (e.g. scissors lifting mechanism, lifting mast,) allows the height of the oven loader to be varied for loading and unloading at diffe
47、rent levels in the oven. The loading device comprises a frame and a belt in order to place the pieces of dough in the oven and to take out the loaves when baking has finished.
