Food processing machinery - Planetary mixers - Safety and hygiene requirements EN 454:2000+A1:2009

Publication date:   Feb 28, 2010

Scope

This standard specifies safety and hygiene requirements for the design and manufacture of fixed bowl planetary mixers of capacity greater than or equal to 5 l ) and less than 500 l used to process various ingredients e.g. cocoa, flour, sugar, oils and fat, minced meat, eggs, and other ingredients, in the food industry and shops.
These machines are sometimes used in other industries (e.g. pharmaceutical industry, chemical industry, printing, etc.), but hazards related to these uses are not considered in this standard.
The following machines are excluded:
- accessory planetary mixers;
- continuously fed machines;
- dough mixers );
- experimental and testing machines under development by the manufacturers;
- domestic appliances.
The intended use of the machine, as defined in 3.12 of EN 292-1:1991 and in the manufacturer's instruction handbook, is loading various ingredients, processing them in a stationary bowl by means of appropriate beaters, unloading and cleaning.
Processing is carried out in cycles of variable duration.
It can be either manually or automatically-controlled, in individual cycles or on a cycle repeat basis, etc.
Manual operations are sometimes necessary to add ingredients without stopping the beater.
On machines fitted with a bowl lifting and lowering device or with a device for moving the bowl/head/beater vertically the working position is that when the beater is nearest to the bottom of the bowl.
The significant hazards covered by this standard are mechanical (shearing, trapping, loss of stability), electrical, thermal, ergonomic and also hazards resulting from gas accumulation, noise, inhalation of dust, and lack of hygiene.
This standard does not deal with noise reduction.
The standard applies only to machines manufactured after the date of its issue.
