-----Preparing a tank surface for use in food processing
April 15, 2010
Dear Sirs / madam,
PRICKLING: I would like to know about the process of tank cleaning through the process of preckling. If any one can help me to inform about raw materials and cleaning procedure very grateful. This tank is manufactured for food processing. So you can suggest me the best way of cleaning?
Thanks

Hi, Ben. There may be Saudi government regulations that specify what must be done. Here in the USA, the usual approach would be for the tanks to be made of type 316 stainless steel, and electropolished. The reason for this is that electropolishing smooths the surface, dissolving away any burrs and asperities, whereas mechanical polishing creates a "plowed field" structure. The smooth surface improves cleanability and offers less chance of bacterial contamination. You can read an introduction to electropolishing of stainless steel in the Electroplating Engineering Handbook ⇦ this on eBay, AbeBooks, or Amazon [affil link] . Good luck.

Ted Mooney, P.E.
