European Hygienic Engineering and Design Group
It includes a summary of decontamination requirements and gives an overview on microbiological tests used when qualifying hygienic filling machines. Small motile bacteria penetrate far more easily through microscopic passages than non-motile moulds and yeast.
Supply systems for process air, compressed air and exhaust air systems such as grease filter systems or dust removal units are excluded from the scope of this document. Gaskets of various types were tested for reliability and hygienic aspects using EHEDG cleanability test methods and repeated sterilisation. 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.
Due to the sterilizer process design, the operation and control or inspection and maintenance of the sterilizer there are a risk of untreated or recontaminated product may reach the consumer.
First Edition, July – This document describes the basic hygienic design and safe use of single-body double-seat mixproof valves. This simultaneous cleaning can potentially result in the dangerous situation where product and cleaning liquid are separated by just one single valve seat.
Safe storage and distribution of water in food factories.
This document describes the requirements particularly for liquid foods without particulates. Document guidelinees withdrawn in March Materials of construction for equipment in contact with food.
Guidelines – EHEDG
This document examines integration aspects that can affect hygienic design, installation, operation, automation, cleaning and maintenance and uses system flow guidleines and case studies describing the integration processes and decision steps. First Edition, April – This guideline covers the hygienic aspects of disc stack centrifuges used to separate fractions of liquid food products or to remove dense solid matter from products.
Buy Buy Buy Buy Buy. This document details the test procedure for assessing whether ehed item of food processing equipment, intended for aseptic operation, is impermeable to micro-organisms.
Likewise, systems for storing and distributing water can involve hazards, which could cause water quality to fall below acceptable standards. Hygienic engineering of plants for the processing of dry particulate materials NOTE: Aside from general requirements with regard to materials, drainability, microbial impermeability and other aspects, additional requirements for specific valve types are also described. It describes methods of construction and fabrication, giving examples as to how the principal criteria can be met.
There are many reasons why, in eehedg, pasteurised products sometimes present a microbiological health hazard. The complete passivation process is described and environmental, as well as safety, concerns are discussed. The technique of Ohmic heating was not considered in this paper but may be included in an update being prepared. Second Edition, May – Pasteurization guiedlines a heat treatment aimed at reducing the number of harmful microorganisms to a level at which they do not constitute a significant health hazard.
Furthermore, with a minimum of product transfer between equipment, there are the added advantages of a more compact plant, lower energy consumption and reduced cleaning time.
Second Edition, July ehfdg Valves are essential components of all food processing plants and the quality used strongly influences the microbiological safety of the food production process.
Second Edition, June – Research has shown that hydrophobic membrane filters, with a pore size of 0. These guidelines are intended to assist food gguidelines in the design, selection, installation, and operation of air handling systems to meet the air quality and hygienic requirements of the food manufacturing process.
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. Aside from general requirements with regard to materials, drainability, microbial impermeability and other aspects, additional requirements for specific valve types are also described. The product water distribution system within the plant must be hygienically designed.
Ebedg technology organizations Science and technology in Europe. Whilst primarily aimed at food manufacturing sites, this guidance is also applicable to food service buildings. Upon delivery, a packing machine needs to be checked by a commissioning procedure to be agreed in advance between the food processor and the supplier. It is advisable to conduct in-place cleanability trials see Doc 2 prior ehedy this test in order to verify the hygienic design of the equipment. A method for assessing the bacterial impermeability of hydrophobic guidelinnes filters.
Finally, installation requirements are described and illustrated, taking into account the product environment side, the flushing side and the cartridge design.
Materials covered include carbon-graphite, ceramics, elastomers and metals.
