Alfa Laval's TJ40G tank cleaning machine Heat transfer, separation and fluid handling solutions provider, Alfa Laval, has introduced the TJ40G rotary tank cleaning machine, which uses a high-impact jet stream to effectively clean tough tank residues and minimize the risk of product contamination. The four-nozzle rotary jet head cleans tanks 60% faster than static spray ball technology and because it cleans faster, this new device uses less water and less cleaning agents, reducing operating costs by up to 70%. The Alfa Laval TJ40G is capable of handling tough tank residues as well as solids up to 1 mm in the cleaning fluid in tank sizes 50-1000 m3. This is important for demanding process lines, such as applications within the brewhouse, where both the size and the amount of particles may be re-circulated in cleaning media before completing the cleaning cycle. The rotary tank cleaning machine also has a hygienic self-cleaning construction which ensures that the flow of the cleaning fluid reaches the exterior surfaces of the rotary jet head, as well as the critical interior components such as all bushings, bearings and inner surfaces. This minimizes the risk of product contamination and ensures a high product quality.
