Pasta processing plants. Spreader, stripping and cutting machine, stick return conveyor, stick magazine. Safety and hygiene requirements
| Published By | Publication Date | Number of Pages |
| BSI | 2013 | 50 |
This European Standard applies to spreader, stripping and cutting machine, as well as the stick return conveyor and the stick magazine (see clause 3), used in continuous pasta processing plants able to produce more than 100 kg/h.
This European standard specifies the safety requirements for the design, manufacture and information for safe use of spreader, stripping and cutting machine, as well as the stick return conveyor and the stick magazine classified as stationary units which cannot be moved when in operation.
This European Standard does not apply to:
-
household machines,
-
semiautomatic machines, so called “batch machines” requiring manual loading.
The significant hazards covered by this standard are listed in clause 4.
These hazards and the measures for their reduction are described in the present European Standard.
Ancillary equipment, which is not an integral part of the machinery (e.g. hoppers), is not covered by this European Standard.
This European Standard is not applicable to machines in its scope which are manufactured before the date of its publication as EN.

| 14 | 4.2.2 Mechanical hazards at the spreader (see fig. 1) 4.2.2.1 Automatic lifting of the inlet hood at the start of production creates, a danger zone at this location. When the inlet hood is lifted, hands or fingers of operators can get squeezed between the die and the inlet hood; when the hood is lowered,… 4.2.2.2 The upper cutter for cutting the extruded product represents one particularly hazardous zone. For starting production, the inlet hood is pushed out of the way or is removed and the product extrudes until the discharge is uniform. In this situa… 4.2.2.3 The lower cutter, which cuts the product on the sticks to equal length also represents an area which is particularly hazardous. For maintenance and cleaning, there is free access to the cutter, because the guards have been opened, and there is… 4.2.2.4 The empty sticks being moved on the front of the machine for spreading with product also represents an area which is particularly hazardous. There is a risk of injury (pinching) (zone 4). 4.2.2.5 The conveying belts with the danger of body-parts being drawn-in are further hazard zones (zone 5). 4.2.2.6 The fans for venting the product can cause injuries, such as finger amputation (zone 6). 4.2.2.7 The shredder fan used for transporting the cut-off material back to the extruder can amputate fingers or hands during cleaning. In addition to this, the rotor has accumulated kinetic energy, which can also lead to injuries for a certain time a… 4.2.2.8 The chain transmissions for moving the stick can also cause injuries by pinching and drawing-in (zone 8). 4.2.3 Mechanical hazards on the stripping and cutting machine (see fig. 2) 4.2.3.1 The cutting device, which usually comprises rotating cutter blades is especially dangerous. There is a risk of severe laceration. 4.2.3.2 The stripping and depositing devices represent additional hazard zones. Here, especially the clamping zones may cause danger of pinching (zone 2). 4.2.3.3 The conveying elements for the stripped off and cut or uncut product, such as chains, belts or oscillating conveyors, can cause injuries by pinching and drawing-in (zone 3). 4.2.3.4 The chain transmission and possibly the disk cams of the stick drives, as well as of the stripping device, can cause injuries (pinching) (zone 4). 4.2.3.5 The fan for transporting the remaining product back to the milling device, may cause injuries to the fingers or hands during cleaning. In addition to this, the rotor has accumulated kinetic energy, which can also lead to injuries for a certain… |
| 15 | 4.2.3.6 The side of the cutting machine where the sticks are introduced is normally attached to adjacent machines, for instance to the stick stacker. Uncovered openings and channels may offer free access to the moving parts and thus these may cause in… 4.2.3.7 At the stick removal device there is risk of getting injured at the clamping and drawing-in zones (zone 7). 4.2.4 Mechanical hazards at the stick return conveyor and the stick magazine (see fig. 3) 4.2.4.1 In the stick transfer area and along the conveying elements there is risk of pinching at the clamping points that may cause injuries (zone 1). 4.2.4.2 Driving elements such as chain transmissions, rotating shafts, and stick transfer points may cause injuries due to drawing-in and pinching (zone 2). 4.2.4.3 In case of removal and feeding devices of the stick, there is risk of pinching at the clamping points. 4.2.5 Fluid ejection hazards 4.2.6 Hazards due to unexpected start or failure of emergency device 4.3 Electrical hazards 4.4 Thermal hazard 4.5 Noise hazard |

Access to the area can either be prevented by means of fixed guards or movable interlocked guards or by means of an optoelectronic protective device that shall satisfy EN 61496-1:2004… 5.2.2.4 The lateral conveyor chains and sprockets shall be protected by means of fixed guards or movable interlocked guards. 5.2.2.5 Access to the movable elements, such as chain or belt transmissions, oscillating or rotating parts of drives shall be prevented by means of fixed guards or movable interlocked guards. 5.2.2.6 Access to fans shall be protected by fixed guards in accordance with !EN ISO 13857:2008, Table 4″. 5.2.2.7 During maintenance access to the shredder fan shall be protected by fixed guards. Movable interlocked guards with guard locking may also be used, However, in this case, it shall be guaranteed that the rotor of the fan is at standstill, before … 5.2.2.8 Access to the chain transmissions for moving sticks shall be prevented by means of fixed guards or movable interlocked guards. 5.2.3 Stripping and cutting machine 5.2.3.1 Access to the rotating cutter blades shall be prevented by means of fixed guards or movable interlocked guards with guard locking. 5.2.3.2 Access to the stripping and depositing devices shall be prevented by means of fixed guard or movable interlocked guards. 5.2.3.3 Access to the conveying elements for the stripped and cut or uncut product shall be prevented by means of fixed or movable interlocked guards. 5.2.3.4 Access to the various drive devices shall be protected by fixed guards. Movable interlocked guards with guard locking may also be used. However, in this case, it shall be guaranteed that the rotor of the fan is at standstill, before access is … 5.2.3.5 During maintenance access to the shredder fan shall be protected by fixed guards. Movable interlocked guards may also be used. However, in this case, it shall be guaranteed that the rotor of the fan is at standstill before access is possible. 5.2.3.6 In case the inlet for the stick is not covered by the adjacent machine, the inlet shall be protected by means of fixed guards or by movable interlocked guards. 5.2.3.7 Access to the stick removal and feeding device shall be prevented by means of fixed guards or movable interlocked guards.
