De-dusting of hypoallergenic baby food
Pocket filter of type series INFA-JET AJN for conveying systems
Strict hygienic and quality regulations - according to these the food industry is working. That way also for production of hypoallergenic baby food which is strictly supervised. And this is important; health of babies allows no room for mistakes.
The company Gericke is one of the leading plant manufacturers in this demanding production sector. For the realisation of a new production plant for baby food in Switzerland, the project managers of Gericke decided to count on filters of Infastaub for de-dusting the conveying systems. „It was decisive for us, that Infastaub guaranteed to supply pocket filters in this high quality“, explains Thomas Künzli, Manager Purchasing at Gericke.
Infastaub delivered several pocket filters of series INFA-JET AJN for this project. Taking into account the products to be de-dusted all parts in contact with the product and conveying air were made in stainless steel. Because of of the high hygienic demand the filter pocket support frames in stainless steel are also made in a special design. The filter media are manufactured in food safe needle felt with laminated PTFE diaphragm. In view of the so-called hygienic design of „easy cleanable“ plants the filters have no sharp edges or hollow profiles and the filter housings are glass bead blasted at the outside.
Besides the sterile construction also the Atex regulations for explosion protection had to be considered for the filter design. For some filters a pressure shock resistance of 1.0 bar g was demanded. Thus the production surrounding area is protected against explosions in the interior. In case of an explosion the flame front is led into a secured area.The pocket filters are designed for a volume flow of 25 m³/min each, with an air-to-cloth ratio of 1.25 m³/m²*min. Cleaning of the filter pockets is started by the fully automatic control by differential pressure.
