Engineering approach to optimization of pneumatic transportation processes in the food industry
(2024) Volodin, Sergiy; Mironchuk, Valeriy; Zaporozhets, Oleksandr
The study is aimed at developing and improving mechatronic systems for pneumatic transportation of bulk food products. The relevance of this topic is due to the ever-increasing requirements for the efficiency and accuracy of such systems in modern production processes. Existing models of pneumatic conveying often do not take into account the complex physical processes that occur during the movement of particles in a compressed air stream, such as particle migration, hydrodynamic and electrical interactions. This leads to inaccuracies in calculations and, as a result, to a decrease in the efficiency and reliability of systems. To solve this problem, we developed an experimental mechatronic module that allows us to study the process of pneumatic transportation in detail.

Introduction. The complexity of determining the contact surface of phases and the boundaries of the continuous structure of liquid jets complicates the calculation of phase-contact heat and mass exchange mixing apparatuses. Materials and methods. The condensation process of water steam from a steam-gas mixture on a cylindrical free-falling liquid jet is considered under counter-current movement of the steam phase within a range of flow parameters characteristic of the food industry. Results and discussion. An empirical dependence for determining the onset of jet structure destruction adequately describes the process of its structural changes and is characterized by the fact that an increase in the Reynolds number leads to an increase in the critical height of jet destruction: the jet becomes more resistant to the action of the steam flow. With an increase in the dynamic pressure of the steam flow, corresponding to an increase in the Weber number, which characterizes a sharp decrease in the dimensionless height of dispersion, the jet intensively disintegrated, was destroyed at the outflow point, and was carried away by the steam flow. An original system of dimensionless similarity numbers, based on the results of jet hydrodynamics analysis, allows for determining the temperature change along the jet's length, taking into account the geometric characteristics of mixing heat exchanger distribution devices, flow geometric dimensions, steam-liquid flow parameters, and the thermophysical properties of the media. Empirical dependencies of the heat exchange process, considering the critical height of the existence of the continuous jet structure, are recommended for use in the thermohydraulic calculations of direct phase-contact heat exchange equipment. Conclusion. The novelty of the results lies in the introduction of empirical dependencies for calculating heat exchange, considering the critical height of the existence of the continuous structure of the liquid jet.

The process of creating a packaging machine for a flow-processing system consists of separate stages: the first - a clear definition of technological functions of the equipment and description of the operating conditions of the packaging machine; the second - the search for principles of construction and organization of the structure of the packaging machine for a particular type of food product; the third - the creation of a pilot technical project, evaluation of the main criteria and parameters to ensure all necessary requirements for operation.

Nowadays, pneumoelectric systems (PES) are widely used in various fields of human scientific and technical activity. Such systems are used to solve tasks related to movement, distribution and storage of liquids and gases. They are mainly control systems of mechanical units of various machines and aggregates or control systems of parameters (pressure, flow rate) of gaseous and liquid media. Structural diversity, simple and understandable logic of operation, reliability have expanded the field of application of PEPs for production processes taking into account specific requirements of technical regulations.
