Аннотація: A task of increase of efficiency of dehydration processes of damp dispersive materials is actual for several branches of food and processing productions. In particular to these processes belongs a processing of damp dispersive wastes (alcoholic bard, beer pellets, beet press, coffee and barley slime). In case of decrease of their humidity to 20 – 25% solid phase of the waste can be used as a valuable additive to agricultural fodders or as a high-calorie fuel. This allows to resolve problems of waste utilization and environment protection. Results of previously conducting experiments and calculations demonstrate high efficiency of a method vibro-blowing loading in a closed press-form for dehydration of food industry wastes (alcoholic bard, beer pellets and coffee slime), that provides productivity of removal of liquid phase up to 20 ÷ 25 t / h, specific power consuming 2,7 ÷ 3,2 kW / t and final humidity of wastes 20 ÷ 25%. An aim of the article is to analyze known approaches to study of processing of dispersive materials (pressing, vibration and vibro-blowing loading), to examine a mechanism of fulfilment and efficiency of the process of vibro-blowing dehydration of damp dispersive materials in a closed press-form and to determine dependencies between designated efficiency parameters, working parameters of the dehydration process and physical-mechanical characteristics of processed material. Such analysis should carry out from positions of the mechanics, hydraulics and rheology of damp dispersive materials, separately for their solid and liquid phases and also for different stages of vibro-blowing loading. Elaborated calculating method will allow to create high effective equipment for vibro-blowing dehydration of damp dispersive materials with consideration of necessary characteristics of the working process and the processed material.
