The object of this study is the deformation of an elastic axis with a large deflection of a cantilever clamped absolutely elastic rod under the action of an applied concentrated force. The rod in the free state can have a rectilinear or curved elastic axis. This fact implies a difference in the analytical description of the bending process. However...
Additional heating of fruit raw materials in the drying process by direct passage of alternating electric current makes it possible to intensify the dehydration process by 3–5 times. The amount of added thermal energy during direct electric heating depends, first of all, on the value of the specific electrical resistance of the raw material. Theref...
The object of research is the process of convective and combined drying of apple raw materials treated before dehydration in an ultrasonic bath. The use of pretreatment solves the issue of intensifying the dehydration process and maintaining the quality of the product. Sonication for 5 min reduces the dehydration process by 13.7 %, and at 10 min pr...
The intensification of ultrasonic vibrations for the processing of agricultural products is becoming increasingly important in the food industry, as it can reduce energy consumption for the dehydration of raw materials. The research aims to study the effect of sonication on the change of electrophysical parameters and structure of apple raw materia...
This paper gives examples of the implementation of energy-saving measures in public premises. The introduction of energy-saving measures at enterprises significantly reduces the fixed component of industrial expenditures.
As a rule, educational institutions, for example, public premises, are financed from the state budget, and saving money on util...
Object of research: the process of heating a biological object with various methods of supplying thermal energy, in particular, convective, direct electric and combined methods. Solved problem: intensification of heating of high-moisture biological objects during the drying process. Main scientific results. The expediency of using a combined (direc...
The development of technology and drying equipment tackles a triune task: to intensify drying processes, to save energy, to ensure that proper product quality is achieved. This issue is resolved by modern advancements by supplying thermal energy throughout the entire sample volume. The simplest option among the known techniques is to heat wet raw m...
To intensify the dehydration process, we have proposed a combined method for drying fruits and vegetables using direct electric heating. When biological objects are heated with an alternating electric current, simultaneously with an increase in their temperature, the phenomenon of electroplasmolysis occurs. This effect is widely used in the technol...
