Abstract: A method of draining parts emerging from hot galvanizing baths using a range of vibration excitation frequencies capable of covering the fundamental frequencies of the parts to be drained. Three different methods are disclosed. According to a first method the vibrations are obtaining by exciting with a narrow band white noise the support for the parts to be drained. According to a second method, the vibrations are produced from a single exciter fed with narrow band white noise and energizing vibrators through the medium of amplifiers. According to a third method, the vibrations are produced by a number of small vibrators each of which furnishes one of the frequencies of the chosen spectrum, whereby said vibrators jointly synthesize the narrow band white noise.
