Maximum product yield and optimum cleaning: the Whirlwind technology
Whirlwind is the name of the technology which empties a piping section in two steps and in another two steps cleans and dries. During the first two steps, the product is brought out using an air- or gas stream. In another step, the system is cleaned by adding cleaning media to the air stream, and finally the piping can be dried, if this is wanted. The WHIRLWIND technology also functions with standard components like valves and sensors. It is only limited by major diameter variations within a duct or by blocking elements such as displacement pumps. By using a bypass, such hurdles can also be overcome. On a purpose-built experimental rig, tests were conducted to show that this additional potential can really be achieved. In the given scenario, the additional yield is some 16%. As to the solid results of the pre-tests, the customer decided on the Whirlwind technology.
