The content of this document covers functional requirements, intended use, materials of construction, hygienic design and construction and assessment methods.

Materials covered include carbon-graphite, ceramics, elastomers and metals. 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.

The full text of Guideline 8.

Materials covered include carbon-graphite, ceramics, elastomers and metals. The published guidelines are shown in the table below. It can serve as a guide for suppliers and users of this important component.

First Edition, October – This Guideline describes in detail the hygienic requirements of butterfly valves, slide gate valves and ball segment valves.

General hygienic design criteria for the safe processing of dry particulate materials, Valves are essential components of all food processing plants and the quality used strongly influences the microbiological safety of the food production process.

This document focuses on the overall concept of cleaning validation and is intended as a general guideline for use by food manufacturers and inspectors.

This guideline will assist manufacturers to understand better their responsibilities, based on the principles of GMP, by laying down the general requirements and recommendations for the hygienic manufacture and supply of food-grade lubricants. Any cleaning liquid that leaks across such a seat will contaminate the product.


This guideline does not cover other sources of hazards air, water, personnel.

The objective was to provide a reliable dismountable joint which is bacteria-tight at the product side under the conditions of processing, cleaning and sanitation.

Furthermore, with a minimum of product transfer between equipment, there are the added advantages of a more compact plant, lower energy consumption and reduced cleaning time. This document also covers situations where transfer systems are used as a guidepines procedure.

European legislation requires that handling, preparation, processing, packaging, etc. This guideline stresses the need to identify the sources of micro-organisms that may contaminate food in the packaging process, and to determine which contamination rates are acceptably low.

Products which fail this inherent protection have to be sterilised and in consequence, the equipment must be cleanable and sterilisable. See Doc 1 for guidelines on continuous pasteurisation of liquid foods. It gives guidance on design, construction and installation so that it does not adversely affect food safety and quality.


Finally, installation requirements are described and illustrated, taking into account the product ehwdg side, the flushing side and the cartridge design. Such applications involve hygienic material handling and therefore only rotary valves of approved hygienic design should be used.

First Edition, June – In many areas there is an increasing demand for self stable products. It is important that the plant design takes into account factors affecting the hygienic operation and cleanability of the plant.

The extent and rate guiddlines their ehexg can be adjusted according to acceptable risks of product contamination and also in response to any need for dust control. A suitable-sized tank based on water consumption is essential to minimize stagnation.

Challenge tests for the evaluation of the hygienic characteristics of packing machines for liquid and semi-liquid products, Guidelines for the design of bag, big bag, container and truck discharging systems are presented. Design of mechanical seals for hygienic and aseptic applications.

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. Microbiologically safe continuous pasteurisation of liquid foodsid soil to drop or to be drawn into the main product or container.
