European Hygienic Engineering and Design Group – Wikipedia

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.

These principles apply to open and closed manufacturing operations, surrounding facilities, all being cleaned either wet or dry. To validate the bacterial retention ability of sterilising grade hydrophobic membrane filters, a bacterial aerosol challenge test methodology was developed.

This document describes a test procedure to determine whether equipment can be pasteurised by circulation with hot water. The document details the hygienic design principles that shall be followed when designing and constructing equipment and factories for manufacturing of foods.

The method is suitable for equipment that is already known to be in-line steam sterilisable see also Doc 5. Integration of hygienic and aseptic systems. It mainly refers to the part of the weld in contact with the finished or intermediate product.

Free Documents – EHEDG

Upgrading an existing design to meet hygiene requirements can be prohibitively expensive and may be unsuccessful and so these are most effectively incorporated into the initial design stage. Examples include fresh meat and some meat products, cheeses, ready meals, cut vegetables, etc. The extent and rate of their removal can be adjusted according to acceptable risks of product contamination and also in response to any need for dust control.

Each installation needs to take account eedg local requirements and specialist air quality engineers should be consulted, to assist in the design and operation of the equipment. Microbiologically safe aseptic packing of food products NOTE: This document serves as general guidance only, and the principles may be considered useful guidelnes their application in the production of safe food, and in the development of guidelines for the validation of specialized cleaning or inactivation processes.


Likewise, systems for storing and distributing water can involve hazards, which could cause water quality to fall below acceptable standards. Inspection of welds will be covered in more detail in the next project. Safe storage and distribution of guldelines in food factories. This document examines integration aspects that can affect hygienic design, installation, operation, automation, cleaning and maintenance and uses system flow charts and case studies describing the integration processes and decision steps.

Gaskets of various types were tested for reliability and hygienic aspects using EHEDG cleanability test methods and repeated sterilisation. Airborne contaminants are commonly removed by filtration. Passivation of stainless steel. It is advisable to conduct in-place cleanability trials see Doc 2 prior to this test in order to verify the hygienic design of the equipment.

A suitable-sized tank based on water consumption is essential to minimize stagnation.

Equipment and factories of poor hygienic design are difficult to clean. A method for assessing the bacterial impermeability of hydrophobic membrane filters. Views Read Edit View history. Hygienic Engineering of Spray Dryer and Fluid Bed Plants Buy Second Edition, June – Applications in the food industry require that spray drying should meet hygienic processing standards and all components in contact with product should be hygienically designed and preferably be EHEDG approved.

Hygienic design of pumps, homogenizers and dampening devices Buy Buy Buy Buy Buy Buy Buy Buy Buy Third Edition, April – This updated guideline is meant to specify the technical requirements of pumps, homogenizers and dampening devices including their hygienic application in order to ensure a safe processing and production of food under gukdelines conditions.

A method for the assessment of in-place cleanability of moderately sized food processing equipment. The full text of Guideline 8. This document describes a test procedure for assessing the in-place cleanability of moderately guieelines equipment, such as homogenisers.

It describes guidelines for the hygienic design of packing machines, the handling of packing materials and the environment of the packing machines. Buy Buy Buy Buy Buy. Both single and dual mechanical seals fall under the first two categories, which by definition, are subject to more stringent hygienic demands.

Dry food processing and handling requires equipment that are different from those typically associated with wet and liquid products. Second Edition, March – Dry food processing and handling requires equipment that are different from those typically associated with wet and liquid products.

It is not the intention to be prescriptive in specific validation requirements. After documents 3 and 11this is the third test method in the series.

It does not provide detailed guidance on specific manufacturing processes, products, buildings or equipment. Starting from the basics with regard to design, construction materials, layout, and zone classification of the drying systems to meet hygienic requirements, this paper outlines component design aspects of the processing chamber, with particular attention to the atomization assembly and the distribution grids for fluidization.

Both organizations exchange their guidelies guidelines and standards for expert review and comments before publication. How to comply with these requirements, however, is left to the industry. It stresses the current best practices in design of fish processing equipment and plant to highlight typical hazards and challenges of fish processing and emphasizes the importance of control of the environment.

Second Edition, May – Sterilization is a heat treatment aimed at destroying all vegetative microorganisms and spores to create a product which can be stored at ambient temperature yet minimizing public health hazard. A method for the assessment of in-line sterilisability of food processing equipment Buy Buy Buy Buy Buy Buy Guidflines Buy Buy Buy Second Edition, July – Food processing equipment may need to guideelines sterilised before use, and it is important to ensure that the sterilisation method applied is effective.

A more general overview of composites, ceramics and glass and materials is provided. Finally, installation requirements are described and illustrated, taking into account the product environment side, the flushing guideliness and the cartridge design. Design aspects and the characteristics of materials, surfaces and seals are discussed and additional requirements for aseptic equipment are identified.
