CEN/TC 153 Machinery intended for use with foodstuffs and feed

European Norm

67.260   Plants and equipment for the food industry


This standard specifies safety and hygiene requirements for the design and manufacture of fixed bowl planetary mixers of capacity ≥ 5 l 1) and < 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 2) ; - 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. Operation of processing is carried out in cycles of variable duration. It can be either manually-controlled or automatic, 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 noise, inhalation of dust, and lack of hygiene.
