Повышение энергетической эффективности виброударного обезвоживания отходов пищевых производств

Abstract

The scheme of installation for highly effective vibro-blowing dehydration of a of the food manufactures waste is presented in this article. In comparison with other equipment of similar appointment this installation have smaller consumption of materials and providing essential reduction of auxiliary time with achievement of adequate final humidity of dehydrated waste (22 - 25 %). For increase of power efficiency of processes vibro-blowing dehydration it is offered to carry out them stage by stage with consecutive removal of the free, capillary-connected and adsorbtion-connected liquid. Structural schemes of a waste firm phase in the beginning of each of the specified stages of dehydration, and also the formula for calculation of optimum pressure which is necessary for creating in the environment of a waste during realization of stages for destruction of corresponding communication between phases are resulted. Dependences for definition of duration of stages vibro-blowing dehydration and deleted volumes of liquid on each phase are offered. By means of the given formulas and dependences rational parameters of waste loading for their vibro-blowing dehydration can be calculated, providing at the minimum expenses of time and energy full enough removal of a liquid.
