Les guides techniques EHEDG en Anglais

Discharging d'systems for dry particulate materials (powders) are of importance since they aim at the transfer, in this case of dry solids, from one system into another without powder spillage, contamination or environmental pollution, and therefore relate to food processing safety. Dust control is an important issue around these discharging systems in relation to environmental hygiene and worker exposure.

The introduction of the product into the processing system is therefore a key step in maintaining the sanitation and integrity of the entire process. Many dry systems do not have any additional heating protective steps, as they are merely specialty blending processes. Therefore, any contamination that enters the system will appear to the finished product.

This document describes the hygienic design criteria for dry particulate materials discharging systems. Guidelines for the design of bag, big bag, container and truck discharging systems are presented.

These guidelines are intended for use by persons involved in the design, sizing, and installation of bag, big bag and truck discharging systems operating under hygienic conditions.
