    Process of hop particle precipitation in combined wort brew machine
    (2024) Chepeliuk, Oleksandr; Udodov, Sergiy; Chepeliuk, Olena
    A mathematical model of separating solid particles of crushed hops from wort has been developed to improve the combined wort brew machine. A formula for determining the radius of the sediment formation area, which depends on the characteristics of the medium, the operating modes of the apparatus, and the functions characterising the velocity distribution in the boundary layer, is proposed. A dependence for calculating the deposition rate at which moving particles settle to the bottom of the combined wort brew machine is obtained. Based on the obtained results, recommendations on the design and operating parameters of the apparatus are given.

    Justification of the production lines arrangement based on quantitative and graphic methods for assessing the level of equipment excellence
    (2018) Vasylkov, Volodymyr; Chepeliuk, Oleksandr; Chepeliuk, Olena
    On the example of the estimation of technical and economic indicators of machines for the production of burger products, the task of multicriterial choice of equipment for the production lines arrangement by methods of spectral analysis, Pareto and distance to the goal was solved. The method of spectral analysis is based on the apparatus of dead-end tests, involves comparing all the definite combinations of features which describe the object, has advantages over Pareto and motion to the goal methods, because it provides a generalized mathematical evaluation of the specimens which are considered. After analyzing five indicators (productivity, capacity, capacity of the feeding bin, weight, overall dimensions) of eight samples of equipment for the burger products production from different manufacturers, it has been established that according to the chosen parameters, the preference should be given to the machine Laminerva C/E 653 1ph. The correctness of a decision primarily depends on the correct choice of indicators to be compared. In their composition, in the future it is necessary to include indicators of reliability and durability, as well as quality indicators of finished products.
