AKMH™ Hygienic Design Guide

Hygienic Design

The Food and Drug Administration (FDA) is an agency of the United States Department of Health and Human Services.

The FDA is responsible for protecting and promoting public health through the regulation and supervision of food safety,

vaccines, biopharmaceuticals, blood transfusions, medical devices and other products.

The “European Hygienic Engineering and Design Group” (EHEDG) is a European-based non-government organization

devoted to the advancement of hygienic design and food engineering. European legislation requires that handling,

preparation, processing, packaging, etc. of food is done hygienically, with hygienic machinery in hygienic premises (the food

hygiene directive, the machine directive and the food contact materials directive).

Tested properties with respect to cleaning agents

The testing lab of ECOLAB Deutschland GmbH tested the resistance of the external surfaces to the following industrial

cleaning agents:

» P3-topactive DES

» P3-topax 12

» P3-topax 56

» P3-topax 66

» P3-topax 990

In the process, the surfaces were immersed in the respective cleaning agent at 21°C temperature for 28 days. This

corresponds to approx. 2.500 cleaning cycles with 15-minute contact each with the cleaning agent or 1.500 cleaning cycles

with cleaning and subsequent disinfection. Due to the possible relaxation after each treatment in practice the chemical

attack would be even lower.

Kollmorgen can only give a guarantee for the motor’s lifecycle if the tested cleansing agents are used. Contact Kollmorgen
