This 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 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 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 to 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 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 European Standard. This European Standard is not applicable to machines in its scope which are manufactured before the date of its publication as EN.
