Pasta processing plant - Dryers and coolers - Safety and hygiene requirements
This draft European Standard applies to shaker pre-dryers, belt dryers, rotary dryers, nest pasta dryers, long pasta dryers and coolers (see Clause 3), used in continuous pasta processing plants able to produce more than 100 kg/h.
This draft European Standard specifies the safety requirements for the design, manufacture and information for use for the machines mentioned above, known with the name of dryers and coolers, classified as stationary units which cannot be moved when in operation.
This draft European Standard is not applicable to dryers and coolers, static or semiautomatic requiring manual loading as well as those for special application (i.e. experimental dryers).
Dryers in a pasta plant are machines which reduce moisture by means of warm air ventilation. In the drying process the use of a cooler might be necessary in order to reduce the temperature, maintaining constant the correct moisture of the pasta. The cooling can be obtained in the dryer or in a separate similar machine.
The significant hazards covered by this standard are listed in Clause 4.
These hazards, as well as the measures for their reduction, are described in the present draft European Standard
Ancillary equipment which is not an integral part of the machinery (e.g. hoppers, conveyors, equipment used to produce hot or cold fluids, etc.) is not covered by this draft European Standard.
This draft European Standard is not applicable to machines in its scope which are manufactured before the date of its publication as EN.

For the purposes of this document, the terms and definitions given in EN ISO 12100:2010 and the
following apply.
3.1
dryer
assembly where the pasta is dried
3.2
shaker pre-dryer
assembly of metal mesh tables (usually in stainless steel) which is made to vibrate by different types of
systems causing the product to advance towards the outlet and which is used for drying short cut pasta
(e.g. macaroni), in the first stages of the process, when the pasta advances in thin layers to allow the
evaporation of great quantities of water (see Figure 1)
3.3
belt dryer
assembly of belts which conveys the pasta and which is used for drying short cut pasta and placed just
after the shaker pre-dryers in the drying line (see Figure 2)
3.4
rotary dryer
assembly of a rotating drum which consists of conveying channels placed along the periphery of the
drum and which, as a rule it is used for small dimension short cut pasta and for pastina (e.g. soup pasta,
see Figure 3)

4.2.1 General
The significant mechanical hazards are:
— crushing hazard;

4.2.2 Protruding parts
Parts jutting out of the basic outline beyond the machine frame at low level (e.g. valves and pipes of the
heating, cooling and humidifying plant or cables) may cause a trip hazards with the consequence of
broken bones, see zone 1, Figures 2 and 3. Parts jutting out of the basic outline beside the machine
frame at a middle to high level (e.g. motors or gearbox, valves and pipes of the heating, cooling and
humidifying plant) may cause an impact hazard for body parts and the head with the consequence of
manifold injuries, see zone 1 Figures 2 and 3.
4.2.3 Moving parts
4.2.3.1 Moving parts for pasta conveyance systems, such as sticks, belts, drums, frames, and other
containers, may cause hazards of entanglement, cutting, severing and shearing of fingers, hands, arms
and the body; see zone 2, Figures 1, 2 and 3.
4.2.3.2 Moving parts for driving systems such as chains, gears, shafts etc. may cause hazards of
entanglement, cutting, severing and shearing of fingers or hands; see zone 3, Figures 1, 2 and 3.
4.2.3.3 Fan blades may cause hazards of cutting of fingers, hands, arms or other parts of body.
4.2.3.4 Rotating drums may cause hazards of crushing of the body when falling from supports and
hazards of crushing of the fingers and the hands between driving wheels and the rims.
4.2.3.5 Moving parts of air inlet and outlet gates may cause hazards of cutting or severing of fingers
and hands.
4.2.4 Movable parts
When movable parts, e.g. panels of the insulation booth or guiding plates, are handled they may cause
the hazard of crushing of fingers, arms, feet or other parts of the body and the ejection of hot air, which
may cause injury to the head or other parts of the body; see zone 4 Figures 1, 2 and 3.
4.2.5 Openings in the insulating booth
For the operation of the machine, openings are provided for different purposes:
— inlet and outlet for the product;
— inlets and outlets for fluids, e.g. hot air;
11
---------------------- Page: 13 ----------------------
oSIST prEN 13289:2016
prEN 13289:2015 (E)
— sampling;
— cleaning and maintenance operations.
Openings may cause burn hazard due to hot air ejection with the consequence of injuries to hands, arms
and other parts of the body. Depending on the installation access to moving parts may be possible that
may cause a cutting and shearing hazard for fingers and hands.
When entrance doors, hoods or cover panels for cleaning and maintenance operations are handled, this
may cause hazards of crushing, cutting or severing of fingers, arms and other parts of the body.
In case the operator can enter into the machine, he can be trapped and suffer severe injuries due to
mechanical and thermal hazards that may occur if the machine starts up unexpectedly.
4.2.6 Fluid ejection hazards
Leakage of pressurized pipes, including heat exchangers, or leakage of hydraulic drives may cause the
hazard of fluid release, e.g. water, superheated water, steam and diathermic oil (heating system),
hydraulic oil (hydrauli
