The main objective was to convey the reasons and requirements for hygienic welding and to provide information on how this may best be achieved. This document is superseded by Doc 35, recently published. The subgroup will continue with a guideline on inspection of the quality of welds in food processing machinery. Second Edition, May - Using the general criteria for the hygienic design of equipment identified in Doc 8, this paper illustrates the application of these criteria in the construction and fabrication of closed process equipment.
Examples, with drawings, show how to avoid crevices, shadow zones and areas with stagnating product, and how to connect and position equipment in a process line to ensure unhampered draining and cleaning in-place.
Attention is drawn to ways of preventing problems with joints, which might otherwise cause leakage or contamination of product.
First Edition, March - 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. This is achieved by the destruction of vegetative micro-organisms and relevant bacterial spores. Liquid foods containing particulates are inherently more difficult to process than homogenous liquids due to heat transfer limitations in particulate liquid mixtures and the additional problems of transport and handling.
This paper presents guidelines on the design of continuous and semicontinuous plants for the heat treatment of particulate foods. Ohmic heating techniques are not covered. See also Doc 1 on continuous pasteurisation and Doc 6 on sterilisation of liquid products without particles. Second Edition, May - It is important that the plant design takes into account factors affecting the hygienic operation and cleanability of the plant. The risk of contamination of food products during open processing increases with the concentration of micro-organisms in the environment and their opportunity to grow in poorly designed equipment.
This means that in open plants, environmental conditions, in addition to appropriate equipment design, have an important influence on hygienic operation. The type of product and the stage of the manufacturing process must also be taken into consideration. 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.
It describes methods of construction and fabrication, giving examples as to how the principal criteria can be met. See also guidelines on hygienic design criteria Doc 8hygienic welding Doc 9and the hygienic design of equipment for closed processing Doc Second Edition, July - Valves are essential components of all food processing plants and the quality used strongly influences the microbiological safety of the food production process.
These valves must therefore comply with strict hygienic requirements. The guidelines apply to all valves used in contact with food or food constituents that are to be processed hygienically or aseptically. Aside from general requirements with regard to materials, drainability, microbial impermeability and other aspects, additional requirements for specific valve types are also described.
See also Doc 20 on double-seat mixproof valves. First Edition, September - This paper identifies and defines critical design parameters for welded pipe couplings: easily cleanable in-place; easily sterilisable in place; impervious to micro-organisms, reliable and easy to install.
Gaskets of various types were tested for reliability and hygienic aspects using EHEDG cleanability test methods and repeated sterilisation. 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.

The requirements described in the guideline apply to all pumps intended for the use in safe food processing, including centrifugal pumps, piston pumps, lobe rotor pumps, peristaltic pumps, diaphragm pumps, progressive cavity pumps, screw pumps as well as to homogenizers and dampening devices. Chemical surface treatments such as pickling, passivation and electropolishing can help to assure the successful functional and corrosion-resistant performance of stainless steels for product contact surfaces in the food and beverage industry.
This document explains the general principles of those three processes above: Why they are necessary, when and how they should be applied, how they work and which chemicals are used. Second Edition, June - Research has shown that hydrophobic membrane filters, with a pore size of 0. Investigations were conducted in risk assessment of sterilising hydrophobic membrane filters, evaluating the performance of the filters under a range of operating conditions.
To validate the bacterial retention ability of sterilising grade hydrophobic membrane filters, a bacterial aerosol challenge test methodology was developed. First Edition, July - This document describes the basic hygienic design and safe use of single-body double-seat mixproof valves. Today, food process plants incorporate various multifunctional flow paths.
Often one piping system is cleaned while another still contains product. This simultaneous cleaning can potentially result in the dangerous situation where product and cleaning liquid are separated by just one single valve seat.
Any cleaning liquid that leaks across such a seat will contaminate the product. Therefore, often two or three single seat valves in a "block-and-bleed" arrangement are applied. Second Edition, March - Dry food processing and handling requires equipment that are different from those typically associated with wet and liquid products. This is the first in a series of documents that go beyond equipment design and covers installation and associated practices. In the case of dry materials, other considerations include material lump formation, creation of dust explosion conditions, high moisture deposit, formation in the presence of hot air, and material remaining in the equipment after shutdown.
Appropriate cleaning procedures are described, dry cleaning being favoured to reduce risks of contamination. Third Edition, September - This document is designed as a guide to the implementation and use of food-safe lubricants and lubrication practices.
The document is suitable for use by audit companies and internal auditors and for this should be considered alongside suitable training also available from EHEDG. Third Edition, September - This document is designed as a guide to the production, manufacture and supply of food-safe lubricants and lubrication practices. It is intended for use by lubricant producers but is also a guide for good lubrication practice for all industries.
First Edition, August - This guideline compares the design aspects of different mechanical seals with respect to ease of cleaning, microbial impermeability, sterilisability or pasteurisability.
It can serve as a guide for suppliers and users of this important component. Both single and dual mechanical seals fall under the first two categories, which by definition, are subject to more stringent hygienic demands.
General design criteria and basic material requirements for food applications are explained. Materials covered include carbon-graphite, ceramics, elastomers and metals. 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. Since water treatments can be directly or indirectly part of the production process, this treatment should render the water microbiologically and toxicologically safe. Likewise, systems for storing and distributing water can involve hazards, which could cause water quality to fall below acceptable standards.
It is therefore vital that water storage and distribution in a food manufacturing operation takes place in a controlled, safe way. 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: product water, and utility water.
Furthermore, it summarises appropriate practices for controlling Legionella in water systems. First Edition, December - This document addresses packing systems of solid food products and supplements earlier guidelines. Examples include fresh meat and some meat products, cheeses, ready meals, cut vegetables, etc.
Hygiene requirements of the packaging operations, machinery as well as personnel, are described and reference is made to the American Meat Institute's principles of sanitary design.

And finding translators near me was the next step in this bureaucratic necessity. In Paris, back in , I remember getting a list of all the translators near me while visiting the Turkish consulate in Paris and finding the closest one - an older gentleman who had a typewriter on a little portable desk at the entrance of a building. There was a short line of people waiting to get their birth certificates or diplomas translated and you would give it to him, go take a stroll and come back within an hour or two to pick it up. I have to admit if you got lucky and the line was short, this was the best type of service you could get. But the availability of these translators near me was not guaranteed and their services were not at all cheap. Many years later, I had the same need applying to the university in New York and the international student office of my university asked me to get my transcript translated.
