1.1 This European Standard specifies safely and hygiene requirements for the design and manufacture of dough mixers with rotating bowls of capacity greater than or equal to 5 L1) and less than or equal to 500 L.
These dough mixers are used separately o- in a line in the food industry and shops (pastry-making, bakeries, confectionery, etc.) for manufacturing of dough by mixing flour, water and other ingredients. These machines can be fed by hand or mechanically.
These machines are sometimes used in other industries (e.g. pharmaceutical industry, chemical industry, printing), but hazards related to these uses are not dealt with in this standard.
This European Standard deals with all significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, disassembling and scrapping of dough mixers, wtien they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
1.2 This European Standard does not deal with the following machines:
— planetary mixers (see EN 454); continuously fed machines;
— mixers with stationary vertical bowls;
— experimental and testing machines under development by the manufacturer;
— domestic appliances;
— automatic loading and unloading devices.
1.3 This European Standard is not applicable to machines which are manufactured before its date of
publication as a European Standard.

3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100:2010 apply.
3.2 DescrIption
A dough mixer usually consists of:
— a frame, supporting or containing the drive mechanism and control devices;
— a bowl to contain the ingredients to be mixed. This bowl is driven either mechanically or through the action of the kneading tool on the dough, may be removable, and may tilt;
— one or more kneading tools on a vertical or inclined fixed axis or two special arms mixing the dough. In some cases these devices can be raised to allow bowl or food removal.DIN EN 453 pdf download.
