Potential failure mechanisms and influences of manufacturing processes are also discussed. Due to distribution in residence time, not all products may reach the temperature required for pasteurisation or may do so for too short a time. Hygienic engineering of plants for the processing of dry particulate materials NOTE: How to comply with these requirements, however, is left to the industry.

Micro-organisms which are protected by product residues or biofilms are very difficult or impossible to inactivate and the same applies to process areas if resulting in a recontamination risk. Incidental contact between lubricants and food cannot always be fully excluded and may result in contamination of the food product. First Edition, November – This guideline is intended to advise both, sensor designers and manufacturers as well as those in charge of production machinery, plants and processes about the appropriate choice of sensors and the most suitable way for application in dry and wet processes.

The purpose of this document is to provide manufacturers, users and regulatory personnel with basic information and guidelines relative to equipment passivation. A method for the assessment of bacteria-tightness of food processing equipment Buy Buy Buy Buy Buy Buy Buy Buy Buy Second Edition, July – This document details the test procedure for assessing whether an item of food processing equipment, intended for aseptic operation, is impermeable to micro-organisms.

First Edition, December – This document addresses packing systems of solid food products and supplements earlier guidelines. A more general overview of composites, ceramics and glass and materials is provided.

These guidelines are intended to assist food producers in the design, selection, installation, and operation of air handling systems. This document describes a test procedure for assessing the in-place cleanability of moderately sized equipment, such as homogenisers. Its fundamental objective is the prevention of the microbial contamination of food products. The introduction of the product into the processing system is a key step in maintaining the sanitation and integrity of the entire process.


Furthermore, it summarises appropriate practices for controlling Legionella in water systems. Thermal sterilisation is a process aimed at eliminating the risk of food poisoning and, when used in conjunction with aseptic filling, it aims to extend product storage life under ambient conditions.

Systems for both supply and exhaust air should operate in a hygienic manner and recommendations for the use and installation of various types of filters are listed.

This guideline summarizes the best practice for three water categories used in the food industry: A method for the assessment of in-place cleanability of moderately sized food processing equipment.

Languages Deutsch Edit links. A method for the assessment of in-line sterilisability of food processing equipment. They are intended for use by persons involved in the design, sizing, and installation of bag, big bag and truck discharging systems operating under hygienic conditions.

See also Doc 21 on challenge tests. Safe storage and distribution of water in food factories NOTE: This Guideline is meant to provide guidance on hygienic and safety related issues concerning water management sourcing, storage and distribution and provides recommended practices for two water categories used in the gkidelines industry: A method for assessing the in-place cleanability of food processing equipment Buy Buy Buy Buy Buy Buy Buy Buy Buy Buy Buy Third Edition, Julyupdated June – The method is intended as a screening test for hygienic equipment design and is not indicative of the performance of eheddg cleaning processes which depend on the type of soil.

First Edition, August – This guideline compares the design aspects of different mechanical seals with respect to ease of cleaning, microbial impermeability, sterilisability or pasteurisability. Continuous Pasteurization of Liquid Food Buy Buy Buy Buy Buy Second Edition, May – Pasteurization is a heat treatment aimed at reducing the number of harmful microorganisms to a level at which they do not constitute a significant health hazard.


Hygienic Design Guidelines

This method is not as sensitive as the microbiological method described in Doc 2. Materials covered include carbon-graphite, ceramics, elastomers and metals.

Thus, it is necessary to determine under which conditions equipment can be sterilised. Guidelines for the design of bag, big bag, container and truck discharging systems are presented. This means that in open plants, environmental conditions, in addition to appropriate equipment design, have an important influence on hygienic operation.


It clarifies the difference in risk of infection between aseptic processing and aseptic packing and recommends that aseptic packing machines be equipped with fillers that are easily cleanable, suitable for decontamination and bacteria-tight.

Retrieved from ” https: Often one piping system is cleaned while another still contains product.

This paper deals with the principal hygienic requirements for equipment for open processing and applies to many different types, including machines for the preparation of dairy products, alcoholic and non-alcoholic drinks, sweet oils, coffee products, cereals, vegetables, fruit, bakery products, meat and fish. The first section describes a management programme: A method for the assessment of in-line pasteurisation of food processing equipment.

Appropriate cleaning procedures are described, dry cleaning being favoured to reduce risks of contamination. It deals with tube and pipe systems with less than 3. Both organizations exchange their draft guidelines and standards for expert review and comments before publication.

A method for assessing the bacterial impermeability of hydrophobic membrane filters.

European Hygienic Engineering and Design Group

These valves must therefore comply with strict hygienic requirements. A suitable-sized tank based on water consumption is essential to minimize stagnation. The degree of cleanliness is based on the removal of a fat spread soil, and is assessed by evaluating the amount of soil remaining after cleaning by visual inspection and swabbing of the surface.

System requirements are described for three categories of water used:
