Analysis of energy consumption during work of breadcutting machine
(2012) Lukianenko, Bogdan; Gubenia, Oleksii; Telychkun, Volodymyr
In scientific and reference books there are no designed procedures to determine the drive power of cutting and feeding mechanisms of bread-cutting machines, with a bundle of tape serrated knives. Laying on the assaying of the scientific literature, critical parameters of process of cutting of bread are defined such as: rate of cutting and feeding, structurally - mechanical properties, force of cutting, cutting mode. Based on this data an analyze was conducted on the power of mechanisms of the bread-cutting machines, and it was developed a designing procedure of drive power of cutting and transportation mechanisms. The mathematical dependences which were determined allowed us to calculate drive power at known force and rate of cutting, to analyze and optimize expenditures of energy in the machine. Results of probes could be used in calculation of the cutting equipment and when making a choice on the optimal parameters of work.
Analysis of the legislation of food products labeling
(2014) Lukianenko, Bogdan; Gubenia, Oleksii; Pashkova, Katsiaryna; Stefanov, Stefan
Competitiveness of Ukrainian products in the world market can be raised by development of the Ukrainian legislation on marking of food products. A theme urgency especially considerable if to consider an aggravation of mutual relations between the Customs Union and the countries-neighbours.
Friction at bread cutting by a disk knife
(2014) Lukianenko, Bogdan; Gubenia, Oleksii; Telychkun, Volodymyr; Stefanov, Stefan
Friction negatively influences quality of a cutting. The bread structure fails, occurs spalling, bread adheres to a knife.
Modeling of cutting of multilayer materials
(2013) Guts, Viktor; Gubenia, Oleksii; Lukianenko, Bogdan
In the food industry products which have homogeneous or difficult multilayer structure are cut. Process of cutting for each case has many differences. It is necessary to fix features of movement of a knife in different products behind structure, and to improve regime parameters of operation of the cutting equipment.Materials and methods. Mathematical simulation of movement of a knife in a product on the basis of the power assaying and the decision of differential second-kind equations is spent. For experimental researches installation of pendulum type with a knife that allows to change easily rate of a knife and a store of its kinetic energy is used. Mathematical sample pieces of cutting which allow to define force of cutting at different rates of a knife and product structure, and techniques of definition of factors, in mathematical sample pieces of cutting for different conditions of process are developed. If the product has a thin strong envelope, the force of cutting at knife approach to an envelope grows. It is reduced recommendations concerning conditions of movement of the cutting instrument, its orientation, concerning stratums to a product. At first it is necessary to cut a thin strong stratum, and then all volume of a product. It considerably reduces energy consumptions at cutting.
