This ultrasonic screen cleaning system achieves much more efficient screening, especially with very fine screen cloths, which can significantly increase the screening throughput with the same screening surface. Screening in the range of up to 20 µm is possible. In addition, clogging of the meshes or sticking of difficult-to-screen products is prevented. It is particularly suitable for contamination-free screening, such as for food and pharmaceutical products. The microprocessor-controlled hi-tech sound generator uses a converter to excite a sound transmission ring with bonded screen mesh. This distributes the ultrasonic waves over the entire screen surface and reduces the frictional resistance between the screen product and the screen mesh. This simple and patented method prevents the development of resonance effects, which are the cause of high temperatures (“hot spots”) and reduces the mechanical load on the screen frame and mesh. The amplitudes and frequency bandwidths can be individually adapted to each screen and each screening task. This system is designed so that it can be retrofitted to all new or existing screening machines. Product throughput is increased many times over because the powder passes through the sieve more quickly Converter and cable outside of the machine, therefore no risk of foreign particles in the product Easy to use with ATEX specification Increase in screening accuracy No damage to the screen mesh due to mechanical cleaning systems Contamination-free screening
