This European Standard specifies requirements for the design, installation, operation and maintenance of batch production fixed or tilting horizontal bowl type mixers with one or two rotating shafts with or without movable blades. These mixers are used to mix, knead and homogenise food for animal or human consumption in powder, paste or liquid form. The mixers can be floor mounted or transportable (with or without castors). They are intended to be used when stationary.These machines are used in feed mills and factories which produce, work on or process foodstuff, for example biscuits, bread, chocolate, cereal products. This European Standard does not deal with the use of the machine in potentially explosive atmospheres.This European Standard deals with the significant hazards, hazardous situations and events relevant to mixers with horizontal shafts, when used as intended and under the conditions foreseen by the manufacturer.This European Standard also specifies food hygiene requirements.The feeding equipment, the dosing equipment, and the requirements of equipment for the supply of inert gases, and for heating and cooling, are excluded from the scope of this European Standard.The hazards due to the unloading equipment (container, discharge belt, etc.) are not dealt with in this European Standard.When drafting this European Standard, it has been assumed that the machines are not intended to be cleaned with a water jet.This European Standard is not applicable to mixers with horizontal shafts which are manufactured before the date of publication of this European Standard by CEN.
