BS EN 13389 is a European standard on food processing machinery that discusses the safety and hygiene requirements for mixers with horizontal shafts to ensure protection to workers against machinery hazards.
BS EN 13389 specifies requirements for the design, transport, 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.
BS EN 13389 deals with the significant hazards, hazardous situations, and events relevant to mixers with horizontal shafts, when they are used as intended and under conditions of misuse which are foreseeable by the manufacturer. BS EN 13389 also specifies food hygiene requirements.
When drafting BS EN 13389, it has been assumed that the machines are not intended to be cleaned with a water jet.
Note1: BS EN 13389 does not deal with the use of the machine in potentially explosive atmospheres.
Note2: The hazards due to the unloading equipment (container, discharge belt, etc.) are not dealt with in BS EN 13389.
BS EN 13389 on the safety and hygiene requirements for mixers with horizontal shafts is useful for:
A horizontal mixer means a machine that combines ingredients by agitating with beaters rotating in an arc on a horizontal shaft. A horizontal mixer may have a tilting or non-tilting bowl.
BS EN 13389 provides you with guidance on a list of significant hazards, the safety and hygiene requirements and/or protective measures, verification of safety and hygiene requirements and/or protective measures, noise test code for mixers with horizontal shafts, the principle of design to ensure the cleanability of mixers with horizontal shafts, etc.
The safety and hygiene requirements provided by BS EN 13389 assist you in improving the performance and quality of mixers with horizontal shafts and ensure protection to workers against mechanical hazards, electrical hazards, thermal hazards, and hazards resulting from the inhalation of harmful mists and dust.
With obedience and compliance to BS EN 13389, you can enhance mixers with horizontal shafts’ effectiveness and efficacy and manufacture a standardized product.
