25、N 12041:2014 (E) 5 Introduction This document 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 differe

26、nt 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 the provisions of this type C standard. BS EN 12041:2014EN 12041:2014 (E) 6 1 Scope

27、1.1 This European Standard applies to the design and manufacture of moulders of the types described from 3.2.1 to 3.2.4 and illustrated in Figure 1 to Figure 3. These moulders are used separately or in a line in the food industry and shops (pastry-making, bakeries, confectionery, etc.) for flattenin

28、g, rolling and, but not necessarily, elongating pieces of dough. These machines can be fed by hand or mechanically. This document deals with all significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, di

29、sassembling and scrapping of moulders, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). 1.2 This European Standard does not deal with: designs of moulder other than those described from 3.2.1 to 3.2.4; experimental and

30、 testing machines under development by the manufacturer; domestics appliances; bagel machines; additional hazards generated when the machine is used in a line; dough and pastry brakes (see EN 1674). 1.3 This document is not applicable to machines which are manufactured before its date of publication

31、 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.

41、 lump of dough into a flat piece, the shape of which depends on the form of the lump; for instance a pre-rounded lump can be transformed into a round or oval shape disc 3.1.2 rolling transformation of the flattened dough lump into a short cylindrical shape 3.1.3 elongating transformation of a short

42、cylindrical shape of dough into a long cylindrical shape BS EN 12041:2014EN 12041:2014 (E) 8 3.2 Description 3.2.1 General Machines may be manually or automatically fed (for example by discharge conveyor from the intermediate prover, see Figure 1). Dough pieces are flattened between at least two cyl

43、inders (2), rolled between at least two surfaces (e.g. two moving belts, or one belt and a fixed plate, or one belt and a fixed band) (3), and, but not necessarily, elongated (4) in the same way (see Figure 1). Discharge may be manual or by conveyor. The machine can be equipped with a flour duster.

NOTE Product quality depend

45、s on careful handling of the dough and in particular on manual introduction of the dough without any excessive drop.

46、t These machines without a specific elongating action are used mainly to produce rolled bread with soft or hard dough. The piece of dough is manually placed on the inlet conveyor belt (see Figure 2 and Figure 11) or can pass onto it by gravity, transfer, etc., from other machines (conveyor belts, in

47、termediate provers, etc.), at different angles from the axes of cylinders in order to obtain several shapes of bread (e.g. banana, mantovane, barillini, bocconcini, etc.). NOTE The flattened piece of dough is rolled by two counter-rotating belts, which are placed one over the other, divergent toward

48、s the outlet and with different linear speeds. When the rolled piece of dough comes out from the above said rolling belts, it passes to a rigid plate, which can be under the infeed belt or at the opposite side or at both sides (see the example shown in Figure 11), or to a conveyor belt (like the “di

49、scharge belt” (5) in Figure 1), different from the belts which carry out the dough rolling action.
