Food processing equipment - Motor-operated equipment - Planetary mixers
1 Scope
This document specifies the technical requirements and inspection rules for planetary mixers fitted with a bowl-shaped drum (hereinafter referred to as the “drum”), defines the relevant terms and definitions, describes the classification of structure, verification of measures and relevant hazards in different zones, and gives information for their use.
This document applies to planetary mixers with a drum capacity of ≥5L and ≤200L for processing various food materials in food shops. Food materials include cocoa powder, flour, sugar, oils and fats, meat stuffings, eggs and other materials. This document may be used as a reference for mixers in food industry, pharmaceutical industry, chemical industry, printing industry and other industrial places.
This document does not apply to:
——Auxiliary accessories of planetary mixers;
——Continuous feeders;
——Vertical dough mixers (GB/T 22748);
——Whipping mixers without parallel shafts;
——Equipment in the experimental stage of development by the manufacturer;
——Household apparatuses.
