Alfa Laval TJ40G rotary tank cleaning machine

The Alfa Laval TJ40G rotary tank cleaning machine uses a high-impact jet stream to effectively clean tough tank residues and minimise the risk of product contamination. The four-nozzle rotary jet head cleans tanks 60% faster than static spray ball technology, according to the company, which says the device uses less water and cleaning agents, thereby reducing operating costs by up to 70%.

The machine 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 recirculated in cleaning media before completing the cleaning cycle.

As well as cleaning the tank interior, the device also cleans itself — inside and out. Its construction ensures that the flow of the cleaning fluid not only reaches the exterior surfaces of the rotary jet head, but also the critical interior components such as all bushings, bearings and inner surfaces.

Self-cleaning features include directional flow from small jets in the hub that clean the exterior of the machine. A low pressure loss over the machine provides increased cleaning efficiency compared to other tank cleaning machines running at the same inlet pressure. This results in a lower cleaning cost as the unit can run at lower pressure/flow compared to other tank cleaning machines.
