After several studies and receiving quite a few food multinational requests, PRODEC has developed the so-called “hygienic design” for some of their equipment. The design of an equipment or facilities is considered “hygienic” as long as establishes, as a preventive measure, the specifications to reduce or eliminate the risk of a source of pollution, both directly and indirectly.
As regards the machine frame design:
PRODEC achieves the hygienic design thanks to the use of open frames in the machine structure leading to a better visibility, ease of cleaning and sanitation.
It´s avoided the use of tubular sections, preventing this way the creation of hollow bodies inside the chassis. To prevent dirt accumulation we use open frames instead. Crossed supports are rejected wherever possible, using angles and brackets to make the components of the structure stronger.
It is also necessary to avoid the corners where dirt can be accumulated by using rounded corners. When flat surfaces are installed they must have a straight angle of 45 degrees from the horizontal.
As regards aluminum frames design:
A frame with no corners must be used to prevent dirt accumulation in addition to being designed to make their cleaning, access and inspection easier.
