EHEDG 2017 (replaces the 1993 edition) Seiten / pages: 22 Thermal sterilisation is aimed at eliminating the risk of food poisoning and, when used in conjunction with aseptic filling, at achieving extended product storage life under ambient conditions. Whereas pasteurisation destroys vegetative micro-organisms, sterilisation destroys both vegetative micro-organisms and...

EHEDG 2nd Edition 2004 ISBN: 0-9075-0314-4 Seiten / pages: 9 This document details the test procedure for assessing whether an item of food processing equipment, intended for aseptic operation, is impermeable to micro-organisms. Small motile bacteria penetrate far more easily through microscopic passages than (non-motile) moulds and yeasts. The facultative anaerobic...

Link for free download see below Third Edition, March 2018 This document describes the principles for hygienic design of equipment and factories intended for food manufacturing. The fundamental reason for applying hygienic design principles is to prevent contamination of food products. Equipment and factories of poor hygienic design are difficult to clean. The document...

EHEDG 1993 ISBN: 0-0750-3136 Seiten / pages: 19 This document describes the techniques required to produce hygienically acceptable welds in thin walled (

EHEDG 2nd Edition 2007 ISBN: 987-0-9075-0327-9 Seiten / pages: 21 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,...

EHEDG 1994 Seiten / pages: 24 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...

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...
