Abstract
This invention relates to an improvement in dehydrating equipment, in particular double belt presses, in which an upper endless sieve belt is guided by means of parallelly supported rollers, with parallelly supported rollers being similarly arranged below and on which a lower endless sieve belt is guided, the suspension to be dehydrated being introduced between the sieve belts, the sets of rollers being divided into a wedge section, a registering section, a precompression section and a main compression section, the improvement comprising that the compression rollers in the pre-compression section are composed of several pieces extending across the equipment and, when viewed in the direction of motion of the sieve belts, are alternatingly offset backwardly or forwardly, the ends of the rollers penetrating the region of adjacent rollers in overlapping fashion.
