GB/T 23242-2022Food processing equipment - Motor-operated equipment - Food processors and blenders (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.

This document replaces GB 23242-2009 "Safety and Hygiene Requirements for Food Processing Machinery, Food Choppers and Mixers". Compared with GB 23242-2009, in addition to structural adjustment and editorial changes, the main technical changes are as follows.

--- Changed "Terms and Definitions" (see Chapter 3);

--- Added "Overview" (see Chapter 4);

--- Added "inspection rules" (see Chapter 8).

Introduction

Using food choppers and blenders can introduce a variety of mechanical and other risks.

This document includes product safety and risk requirements and can be used as a supplement to mechanical design standards such as GB/T 22747-2022. The structure of the Machinery Safety Series Standard is.

--- Class A standard (basic safety standard), giving the basic concepts, design principles and characteristics applicable to all machinery.

--- Class B standard (general safety standard), involving a safety feature of machinery or a class of safety guards with a wide range of use.

- Category B1, specific safety features (such as safety distance, surface temperature, noise) standards;

- Class B2, safety devices (such as two-hand control devices, interlocking devices, pressure-sensitive devices, protective devices) standards.

--- Class C standard (machine safety standard), a standard that specifies detailed safety requirements for a specific machine or group of machines. This document is a Category C standard.

When the provisions of this document differ from published standards for Type A or Type B, for machines that have been designed and manufactured in accordance with Type C standards For equipment, the provisions of this document take precedence over the provisions of the Class A standard or the Class B standard.

1 Scope

This document specifies an overview of food choppers and blenders, descriptions of relevant hazards, technical requirements, verification of measures, inspection rules and use information.

This document applies to food shredders and mixers with fixed buckets when processing products, and the capacity of the buckets is <= 150L.

This document applies to machines for chopping, stirring, whipping and mixing of semi-finished, finished and raw foods.

Note: This type of machine is mainly used in the food and catering industries such as restaurants, hotels, coffee shops and taverns, as well as in the canteens of industrial and mining enterprises.

This document does not apply to.

--- Household machines;

--- Machines dedicated to food industry processing (eg. pet food, canning industry, industrial meat processing);

--- Small machines specially designed to mix liquids (eg with an impeller, usually driven from the top).

This document does not cover.

--- Vibration hazard;

--- thermal hazard;

--- Hazards caused by pressure.
