EHEDG 2018 Seiten / pages: 40 Spray dryer and fluid bed plants are widely used in the food processing industry for producing dry particulate materials from liquid concentrations in a continuous process. The drying process involves product handling in a warm and humid environment and thus a potential hygienic risk is involved. Therefore, applications in the food industry...

EHEDG 2005 ISBN: 0-9075-0323-3Seiten / pages: 57 This guideline aims to offer a practical 'handbook' for those responsible for the specification, design and manufacture of food processing equipment. It offers guidance on the ways in which materials may behave such that they can be selected and used as effectively as possible. The properties and selection procedures with...

EHEDG 2005 ISBN: 0-9075-0324-1 Seiten / pages: 16 The introduction of the product into the processing system is a key step in maintaining the sanitation and integrity of the entire process. Discharging systems are designed to transfer, in this case dry solids, from one system into another without powder spillage, contamination or environmental pollution. Many dry systems do...

EHEDG July 2006 Seiten / pages: 29 Abundantly illustrated, this paper provides guidelines for the correct execution of on-axis hygienic (sanitary) welding between pipe segments, or between a tube and a control component (e.g. valve, flow meter, instrument tee, etc.) It deals with tube and pipe systems with less than 3.5 mm wall thickness, built in AISI 304(L) (1.4301, 1.4306...

EHEDG 2007 Seiten / pages: 21 Transfer (also known as transport or conveying) of dry particulate materials (products) between or within plant components in a process line is well practiced in the food industry. The transfer operation must be carried out in a hygienic and safe manner and the physical powder properties must not be affected during this operation. In this...

EHEDG 2017 (replaces the 2007 edition) Seiten / pages: 33 Rotary valve selection and operation has a considerable influence on the hygiene standard of a process line and thus, the end-product quality of the dry material handled. Incorrect selection of valve type and size must be regarded as a serious hygienic risk in the food industry. Hence, only valves strictly conforming...

EHEDG June 2009 Seiten / pages: 14 In many areas there is an increasing demand for self stable products. However, microbial product contamination limits the shelf life of sensitive products which are not protected by any preservatives or stablised by their formulation. Products which fail this inherent protection have to be sterilised and in consequence, the equipment must...

EHEDG October 2010Seiten / pages: 26 Every process plant is equipped with valves. In dry particulate materials processing, valves fulfil numerous functions: shut-off and opening of flow lines, direction and flow control, protection against excessive orinsufficient pressure and against intermixing of incompatible media at intersection points in the process. The quality of the...

EHEDG 2011 Seiten /pages: 22 Every process plant is equipped with valves, which fulfil numerous functions. These include line shut-off, opening, change-over and control of product flow, while also giving protection against both excessive or insufficient pressure and intermixing of incompatible media at intersection points in the process line. Diverter valves are applied...

EHEDG 2013 Seiten /pages: 24 Special demands are made with regard to CIP-capability of disc stack centrifuges used in the food processing and pharmaceutical industry. These requirements, their implementation and related design principles are handled in detail in this guideline. This guideline covers the hygienic aspects of disc stack centrifuges used to separate fractions of...

EHEDG 2016 Seiten /pages: 76 This document provides guidance to the hygienic design of belt conveyors specifically for use in an environment where wet cleaning is mandatory, and is supplementary to the general requirements and standards for hygienic equipment. The guidance is relevant where the foodstuff is in direct contact with the conveyor and also in areas where there is...
