The mathematical model of working unit co-operation of plant lifter with soil and roots of plants for optimization of plant lifter’s different parameters is developed
In this article, the improved methods of cryoconserva-tion and cryoseparation of food vegetative raw were investigated. Also, the authors have investigated the proposed improves of cryocrushing and cryosepara-tion technologies of vegetative raw
Shrinkage of a fumed oak wood values that was sub-jected to preliminary thermo chemical processing and raw are investigated. Conformities to the law of influ-ence to processing modes on shrinkage size are estab-lished
In the article questions of optimal control of tempera-ture maintenance in a cattle-breeding complex are considered. Possibility of use of discrete management is shown. The optimum step of digitization is found
Technologies and agro technical requirements to sprinkling machines depending on its flow, the area of irrigated area and agro-climatic zone are presented in the article
Based on imitating modeling the analysis of effi-ciency of a chain brush cutter with working body of a new design is carried out. Influence of frequency of rotation of the work body on indicators of quality of removal of young growth and power expenses is investigated
The article deals with the method of experiment and results of heat tests of transformer. This transformer intends for transformation of single-phase voltage into three-phase one. Use of this transformer allows to transform three-phase voltage in single-phase with the minimum decrease in indicators of quality of voltage from a power line
The turbulent movement of the liquid with dispersed phase in the channels of thin layer clarifiers and hydrocyclones is reviewed. The evaluation of the dimensions of the particles, which are taken by the turbulent pulsation is performed. The turbulent sedimentation of the fine phase is researched as a type of a process of diffusion. Using the equations from the theory of mass transfer and the edge of the turbulent level, the coefficients of the speed of the transfer of the particles are acquired. The results of the calculations, covering the effectiveness of the turbulent separation are provided, with the use of the models of perfect mixing and displacement
In the article a reproduction process of material and technical base at agricultural enterprise is given and its basic tendencies and existing ways of common productive facilities reproduction are analyzed
In this article, a possibility of a heat supply of housing and communal services with use of thermal pumps is considered. The area, in which thermal pump is the most expedient way to use for heat supply systems is shown
