Food processing machinery - Moulders - Safety and hygiene requirements
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 flattening, 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, disassembling 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 3.2.3;
- experimental and 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 as a European standard.

Principles for design and selection (ISO 14119:2013) 3 Term, definition and description 3.1 Terms and definitions For the purposes of this document, the terms and definitions given in EN ISO 12100:2010 and the following apply. 3.1.1 flattening transformation of the 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 cylindrical shape of dough into a long cylindrical shape SIST EN 12041:2015
Key 1 feeding (by belt) 2 flattening 3 rolling 4 elongating 5 discharge Figure 1 — General principle 3.2.2 Type 1: Moulder with manual feeding by gravity These machines are used mainly to produce long bread with soft dough (e.g. French baguette) (see Figure 2 and Figure 4). NOTE Product quality depends on careful handling of the dough and in particular on manual introduction of the dough without any excessive drop. SIST EN 12041:2015
Key 1 feeding 2 flattening 3 feed chute Figure 2 — Feeding by gravity 3.2.3 Type 2: Compact moulder without elongating system and with feeding by belt 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, intermediate 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 towards 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 “discharge belt” (5) in Figure 1), different from the belts which carry out the dough rolling action. SIST EN 12041:2015
Key 1 feeding 2 flattening Figure 3 — Feeding by belt 3.2.4 Type 3: Moulder with elongating system and with feeding by belt These machines are mainly suitable for producing large rolled bread (long loaves) laminating, rolling and elongating pieces of (usually) soft dough. The piece of dough is placed on the inlet conveyor belt (see Figure 3 and Figure 6) manually or can pass onto it by gravity, transfer etc. from other machines (conveyor belts, intermediate provers, etc.). The machine can be equipped also with two bars between which the rolled dough pass during the elongation phase for limiting the length of the long loaves and flattening their ends (e.g. long loaves for tin bread). The product outlet can be as described for the type-2 moulder; it can also fall by gravity in a special container (e.g. long loaves for tin bread). 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). Figures 4, 5 and 6 show the danger zones. SIST EN 12041:2015

In addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards, which are not dealt with by this document. 5.2 Mechanical hazards 5.2.1 General Where reference is made to interlocking devices throughout Clause 5, they can be interlocked without guard locking and shall comply with EN ISO 14119:2013, Clauses 5, 7 and 8. Where the interlocking mechanism has movable parts, e.g. position switches, these shall be protected from contamination with dough or dry ingredients, e.g. by mounting them within the machine body. The safety-related parts of the control system shall present at least a performance level “c” defined in accordance with EN ISO 13849-1. When fixed guards, or parts of the machine acting as such, are not permanently fixed e.g. by welding, their fixing systems shall remain attached to the guards or to the machinery when the guards are removed. The stopping time of the machine, when protective devices (e.g. interlocking guards, trip device) are actuated, shall be less than or equal to 1 s from their actuation. Restarting shall only be possible by actuating the starting control. SIST EN 12041:2015

5.2.2.3 Type 2: compact moulder without elongating system and with feeding by belt Access to the rollers shall be prevented. This may be achieved by the provision of: — a fixed feed guard (e.g. feed tunnel) on the conveyor, see EN ISO 13857:2008, Table 4; — an impeding device on the conveyors: a fixed or an interlocked feed chute/chicane with the dimensions given in Figure 10; — a movable interlocking guard acting as a trip device (see Figure 11). The guard shall comply with Table 2 and be free to move vertically or near vertically at the feed opening. Openings in the guard shall comply with EN ISO 13857:2008, Table 4, except for the feeding opening. SIST EN 12041:2015

If the stopping time of the flour duster is more than 1 s, the movable guard shall be interlocked with guard locking. If there are no mechanical hazards (e.g. if the feed consists of a spindle with rubber spokes or notches, or if the flour is sprinkled by a vibrating device) due to the flour feed system and if a guard is necessary to prevent dust emission (see 5.7), this guard shall automatically be closed (e.g. by gravity, etc.). In this case, an interlocked guard is not necessary. 5.2.6 Loss of stability 5.2.6.1 Machines shall be designed to be stable and shall comply with 5.2.6.2 and 5.2.6.3. For machines designed to be fixed to the floor, the instruction handbook (see 7.2) shall indicate the values of forces at the fixing points. 5.2.6.2 Free standing machines without castors or machines installed on a base frame without castors shall be stable when tilted 10° from the horizontal plane in the most unfavourable direction. 5.2.6.3 Free standing machines with castors or machines installed on a base frame with castors shall have at least two castors (or sets of castors) fitted with a locking device, and shall comply with the provisions of 5.2.6.2. 5.3 Electrical hazards 5.3.1 General Electrical equipment, for example switches, that may be exposed to water, e.g. during cleaning, shall be protected to an appropriate IP rating according to EN 60529 and EN 60204-1. The electrical equipment shall comply with EN 60204-1, with the precisions given in the following subclauses (see 5.3.2 to 5.3.5). SIST EN 12041:2015
