GB/T 41602-2022Food processing equipment—Combined equipment—Rotary rack ovens (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 is proposed by China National Light Industry Federation.

This document is under the jurisdiction of the National Standardization Technical Committee of Food Processing Equipment (SAC/TC383).

Introduction

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, which specifies the criteria for specific safety features (eg safety distance, surface temperature, noise);

- Category B2, which specifies the standards for safety guards (such as two-hand control devices, interlocks, pressure-sensitive devices, and guards).

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

This document is a Category C standard.

The relevant machinery and the hazards, hazardous conditions and hazardous events involved are included in the scope of this document.

When the provisions of the C-type standard are different from the A-type standard or the B-type standard, for the machine that has been designed and manufactured in accordance with the C-type standard The provisions of the Class C standard are superior to those of the Class A standard or the Class B standard.

In almost all hazardous situations, at least one design measure, safety precaution or other safety measure to reduce the risk can be taken. These measures need to meet security requirements and control risks, and take corresponding measures to reduce risks as much as possible.

Design measures are the first measures, which are measures to eliminate safety risks by design; if the risks are not within the design scope of the technical process If the design measures and protective measures are used, there are still residual risks, it needs to be informed.

Or instruct users to take measures to avoid or reduce risks.

1 Scope

This document specifies an overview, associated hazard descriptions, technical requirements for the design and manufacture of rotary hot air ovens with one or more rotary trolleys requirements, test methods, inspection rules and usage information.

This document applies to food shops (bakery, pastry shops), canteens of industrial and mining enterprises or food factories specializing in batches of baked goods (including flour, water and other additives) rotating hot air oven (hereinafter referred to as the oven).

This document does not apply to.

--- Manufacturer's experimental and test equipment under development;

--- Household appliances;

--- Rotary hot air oven without trolley.

This document does not deal with the hazards of using gas fuels for gas appliances, nor does it involve the hazards of using oil fuels for oil-fired appliances. using gas, burning Machinery using oil as a heat source may be specified by the manufacturer in the enterprise standard.
