This standard specifies safety and hygiene requirements for the design and manufacture of intermediate provers with moving pocket carriers used in the food industry, pastry-making, bakeries, etc. for giving a resting time to dough between dividing and moulding processes.
The standard covers the technical safety requirements for the design, manufacture, installation, adjustment, operation, cleaning and maintenance of these machines, as defined in 3.12 of EN 292-1:1991 and in the manufacturer's instruction handbook.
The significant hazards covered by the standard are mechanical (shearing, trapping, cutting, loss of stability), electrical, ergonomic and also those resulting from inhalation of flour dust and lack of hygiene.
Noise is not considered to be a significant hazard from intermediate provers. This does not mean that the manufacturer of the machine is absolved from reducing noise and making a noise declaration. Therefore a noise test code is proposed in Annex B.
It applies only to machines manufactured after the date of issue of the standard.
The following machines are excluded :
- rack provers;
- experimental and testing machines under development by the manufacturer.
