This document specifies the safety and hygiene requirements for the design and manufacture of cooking kettles equipped with powered stirrer and/or mixer taking account of installation, operation, cleaning, removal of jammed food, feeding, maintenance and changing the tools. The cooking kettles equipped with powered stirrer and/or mixer are used from catering to small scale-food industry to cook, cool and mix all cold or hot food. They permit addition of ingredients during processing without stopping the machine. NOTE The kettle bowl can be fixed or equipped with a manually or power operated tilting mechanism. In the text that follows, the term "cooking kettles" is used to refer to the equipment covered by this document. This document covers cooking kettles equipped with powered stirrer and/or mixer having technical performances in accordance with the following: thermal energy supply can be electricity, gas (see EN 125 and EN 161), steam or heat-conducting fluid; capacity of the kettle: from 30 l to 600 l (nominal volume); maximum power rating 80 kW; speed of the powered stirrer: 10 rpm to 200 rpm; maximum speed of the mixer: 3000 rpm. The machines covered by this document are not intended to be cleaned with a high pressure water jet. This document deals with all significant hazards, hazardous situations and events relevant to cooking kettles, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This document does not apply to: domestic machines (i.e. capacity of kettles less than 30 l); planetary mixers which are covered by EN 454; food processors which are covered by EN 12852; cooking kettles without powered stirrer and/or mixer having a manual tilting kettle. This document does not deal with hazard due to the pressure on machines with a double jacket. NOTE Depending on the pressure and the volume of the double jacket, the cooking kettle may fall under the scope of the Pressure Equipment Directive (97/23/EC), for the EU market. Noise is not considered to be a significant hazard for these machines. This does not mean that the manufacturer of these machines is absolved from reducing noise and making a noise declaration. Therefore a noise test code is included in Annex A. Vibrations are not considered to be a significant hazard for these machines and no test method is given. Possible hazards relevant to gas supply and heating are not dealt with in this document. NOTE The equipment may fall under the Gas Appliances Directive (90/396/CEE), for the EU market. This document is not applicable to the machines which are manufactured before the date of publication of this document by CEN.
