Attention is drawn to ways of preventing problems with joints, which might otherwise cause leakage or contamination of product.

This guideline is intended to describe the basic ehedgg for equipment and process areas for ehhedg food manufacturing. 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 industrial cleaning processes which depend on the type of soil. 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.

Both single and dual mechanical seals fall under the first two categories, which by definition, are subject to more stringent hygienic demands. The document provides some recommendations with regard to specific utility water applications in the food industry, both for hot water and cold water.

However, it focuses upon sensors eheddg the most common process parameters, particularly temperature, pressure, conductivity, flow, level, pH value, dissolved oxygen concentration and optical systems like turbidity or colour measurements. The guidelines apply to all valves used in contact with food or food constituents that are to be processed hygienically or aseptically.

See also Doc 20 on double-seat mixproof valves. Due to the sterilizer process design, the operation and control or inspection and maintenance of the sterilizer there are a risk of untreated or recontaminated product may reach the consumer. This guideline will assist manufacturers to understand better their responsibilities, based on the principles of Guidelimes, by laying down the general requirements and recommendations for the hygienic manufacture and supply of food-grade lubricants.

This document describes the basic hygienic design and safe use of single-body double-seat mixproof gidelines. It also briefly mentions pinch-off valves, ball and plug valves as well as cone valves.


Eheg is the first in a series of documents that go beyond equipment design ehedt covers installation and associated practices. Guidelines on air handling in the food industry. Any cleaning liquid that leaks across such a seat will contaminate the product.

Whilst primarily aimed at food manufacturing sites, this guidance is also applicable to food service buildings. The particle content dust and micro-organisms can also be controlled to limit the risk of product contamination and hence contribute to safe food manufacture.

European Hygienic Engineering and Design Group

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 food industry: The guidelines summarise the best practice for controlling Legionella in water systems.

Guidelines by description PDF. See also Doc 1 on continuous pasteurisation and Doc 6 on sterilisation of liquid products without particles. This paper sets the minimum requirements for pumps, homogenisers and dampening devices for hygienic and aseptic applications. The guideline does not cover cyclonic types of separators, decanters, basket centrifuges or other types of devices.

guudelines First Edition, April – This document provides guidance to the hygienic design of belt conveyors specifically for use in an environment where wet cleaning is mandatory, and is supplementary to the general requirements and standards for ehedb equipment.

First Edition, September – These guidelines focus on air handling systems installed for food factory building ventilation and its air quality control. 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.

Each installation needs to take account of local requirements and specialist air quality engineers should be consulted, to assist in the design and operation of the equipment.

The correct hygienic design and maintenance of food production systems is considered as a prerequisite to fulfill these requirements. General hygienic design criteria for the safe processing of guidwlines particulate materials. This method is not as sensitive as the microbiological method described in Doc 2.

Hygienic packing of food products. The objective was to provide a reliable dismountable joint which is eheg at the product side under the conditions of processing, cleaning and sanitation.


Commissioning may include physical as well as microbiological tests. See Doc 15 for a test procedure designed for moderately sized equipment. Document was withdrawn in March Safe and Hygienic Treatment, Storage and Distribution of Water in Food and Beverage Factories Buy Buy Second Edition, March Since water treatments can be directly or indirectly part of the guiddlines process, this treatment should render the water microbiologically and toxicologically safe. These valves must therefore comply with strict hygienic requirements.

These valves must therefore comply with strict hygienic requirements. The microbiologically safe continuous flow thermal sterilisation of liquid foods.

Hazards and risks associated with utility water can have significant implications on process reliability. Gaskets of various types were tested for reliability and hygienic aspects using EHEDG cleanability test methods ehecg repeated sterilisation.

Gudielines covered include carbon-graphite, ceramics, elastomers and metals. Second Edition, July – Food processing equipment may need to be sterilised before use, and it is important to ensure that the sterilisation method applied is effective. Hygienic equipment design criteria. It mainly refers to the part of the weld in contact with the finished or intermediate product and the only welding method considered is the GTAW Gas Tungsten Arc Guidrlines, commonly known as TIG without filler material autogenous weldsince this technique is capable of assuring the best performance in the execution of welds for the fabrication of thin wall stainless steel tubing.

Guidelines – EHEDG

This paper presents guidelines on the design of continuous and semicontinuous plants for the heat treatment of particulate foods. Hygienic implications of seal elements and components are also discussed. Finally, installation requirements are described and illustrated, taking into account the product environment side, the flushing side and the cartridge design.

Hygienic design and safe use of double-seat mixproof valves. This document describes a test procedure to determine whether equipment can be pasteurised by circulation with hot water.
