EHEDG 2004 Seiten / pages: 20 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 with the concentration of micro-organisms in the environment and their opportunity to grow in poorly designed equipment. This means...

EHEDG 3rd Edition 2020 Seiten / pages: 6 This document applies to all valves used in contact with liquid food or food constituents processed hygienically or aseptically. Examples of valves are butterfly valves, single-seat valves, mix proof valves, diaphragm valves, sampling valves, etc. The guideline does not apply to disposable valves e.g. for single-use food packaging....

EHEDG 1997 Seiten / pages: 23 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....

EHEDG 4th Edition 2020 Seiten / pages: 49 As standard, a pump for food production shall be constructed according to hygienic aspects and ensure gentle product handling. For special requirements, the pump should optionally allow for retrofitting (e.g. jacketed pump housing, single, quenched or double mechanical seals). Typical pump materials (metallic and non-metallic,...

EHEDG 2014 Seiten / pages: 11 Passivation is an important surface treatment that helps assure the successful corrosion resistant performance of stainless steel used for product contact surfaces (eg. tubing/piping, tanks and machined parts used in pumps, valves, homogenisers, de-aerators, process monitoring instruments, blenders, dryers, conveyors, etc). The purpose of this...

EHEDG 2012 Seiten / pages: 6 Research has shown that hydrophobic membrane filters, with a pore size of 0.22µm, do not retain micro-organisms under all process conditions. Investigations were conducted into risk assessment of sterilising hydrophobic membrane filters, evaluating the performance of the filters under a range of operating conditions. To validate the bacterial...

EHEDG 2000 ISBN: 0-9075-0305-5 Seiten / pages: 19 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...

EHEDG 2001 - rev. 2014 ISBN: 0-9075-0306-3 Seiten / pages: 20 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...

EHEDG 3rd Edition, 2018 Seiten / pages: 27 This document is designed as a guide to the implementation and use of food-safe lubricants and lubrication practices. It is intended for use by food & beverage production companies (and other clean industries) but is also a guide for good lubrication practice for all industries. The document is suitable for use by audit companies...

EHEDG 2018 2nd edition 52 pages 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...
