Introduction
This draft 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 hazardous 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-
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.
Complementary to the hygiene requirements common to all food processing machines, specific
requirements for cleanability and sanitation of the machines in the scope are formulated.

3.4
continuous working machine
machine with non-stop product cycle, where the pre-formed pasta is fed automatically into the machine
and the end product is extracted continuously
4 Descriptions
4.1 Spreader
The spreader (see Figure 1) is placed between the extruder and the dryer. The dough strings,
continually discharged from the extruder, are cut off to a certain length, then placed on the sticks and
cut to the required length on the lower end. Subsequently, the covered sticks are transferred to the
dryer. The empty sticks are taken over from the stick return conveyor and can be heated or treated with
edible oil before they are covered with product.
The cut product remnants are usually transported away from the spreader by means of conveyor belts
and are fed to the extruder by means of a pneumatic conveying line. In order to prevent the still wet
product on the sticks sticking together, it is necessary to have venting devices at several spots.
The spreader can also be equipped with a device for introducing or removing the sticks.

4.2 Stripping and cutting machine
The stripping and cutting machine (see Figure 2) is positioned after the cooler or after the stick stacker.
The sticks with the dried product are taken over, the product is stripped off the sticks and is cut to the
desired length. The cut product is discharged via oscillating conveyors or conveyor belts and is
transferred to the packaging unit or to a stacker. The cut-off material is in most cases transported away
by means of a pneumatic conveying line. The empty sticks are transferred to the stick return conveyor.
Normally, the stripping and cutting machine comprises also a stick removal device, which takes off the
empty sticks to allow for their cleaning or repair.

4.3 Stick return conveyor
The stick return conveyor (see Figure 3) brings the empty sticks from the stripping and cutting machine
back to the spreader. This device is usually positioned underneath the dryers.
In certain cases one of the functions of this return conveyor is the formation of a stick magazine with
the sticks being transported possibly in several tiers.

5 List of hazards
5.1 General
This clause covers all hazards as far as they are considered in this draft European Standard and
identified by risk assessment, significant for this type of machinery and requiring an action to eliminate
or reduce risk.
5.2 Mechanical hazards
5.2.1 General
The significant mechanical hazards are:
— crushing hazard;
— cutting or severance hazard;
— drawing in hazard;
— entanglement hazard;
— shearing hazard;
— impact hazard;
— injection hazard (fluid ejection);
— slipping, tripping and falling hazard.
The examples shown in Figures 1, 2 and 3 illustrate the danger zones associated with these hazards.
5.2.2 Mechanical hazards at the spreader
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, the danger area is underneath the inlet hood (zone 1).
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 situation, the cutting device may become accessible, which means
that fingers and hands of operators are exposed to risk of injury (zone 2).
