A scheme of installation with a hydraulic pulse drive for the two-component three-stage vibro-blowing dehydration of large portions of food production waste (spirit bards, beer pellet, beet pulp, coffee slime) was developed. The installation provides a periodic automated dehydration of waste in the closed type press-form with the stage-to-stage increasing intensity of the load, created through periodic reciprocating-helical motions of the press-form. Thus, as shown by the results of the experiments on the vibropress prototype and calculated data, an increase in workflow performance (by 2.3 times), decrease in energy intensity (by 3.3 times), reduction of the final moisture content of dehydrated coffee slime (by 2%) at an insignificant complication of the installation design and increase in materials consumption in comparison with the one-component vibro-blowing dehydration is provided. Also, parameters of two-component vibro-blowing load of waste such as oscillation amplitude and frequency of the press-form with a portion of the waste, the maximum pressure and the centrifugal force generated in the medium of the waste in the dehydration process, the peak value of the rotation angle of press-form are reasonably selected. Based on the motion equations of actuating elements of the installation at different stages of the operation cycle of its drive, dependences for determining the load parameters, which can serve as a basis for developing a methodology for design calculation of the studied equipment were obtained.
