Purpose. The elaboration of the mathematical models of hydraulic pulse vibropress for preliminary flow vibro-blowing dehydration of humid dispersive materials in closed type press-form, that links the constructive and working parameters of vibropress, physico-mechanical features parameters of loading of the processed material. Method/methodology/approach. The mathematical models of vibropress includes the equations of the balances of energy on different stages of its drive’s cycle, equations of the motion and keeping of impulses of executive elements of vibropress, formulas of theories of hydraulic and mechanical blow. The mathematical models can be are greatly simplified on the grounds of proof of short (pulsed) character of force influence on executive elements of vibropress at the beginning of its working cycle. Findings. The mathematical models, that presented in article, can be used as the base for development of the methods of the design calculation of hydraulic pulse machines for preliminary vibro-blowing dehydration of humid dispersive materials. Originality/value. Using of this machines in food industry allows to get effective solving of a salvaging problem a wastes, such as alcohol bard, beer grain, beet pulp, coffee and barley slime.References
