When producing fuel briquettes, the main material used for pressing is agricultural waste, specifically plant residues, which most often consist of straw from cereal and small-seeded crops. Therefore, the success of the briquetting process largely depends on the properties of their physico-mechanical component.
Within the variation of the studied factors, as the average length of rapeseed straw particles decreases, the density and energy density of the briquettes increase. Also positively affecting these indicators are the increase in the content of binding material (clay or manure), the cone angle of the matrix, and the ratio of the cross-sectional area of the matrix channel to its perimeter. Increasing the moisture content of the pressed material leads to an increase in the density of briquettes and a decrease in their energy density.
To ensure the production of briquettes with a density of over 600 kg/m², both with and without binding material, a round matrix should be used.
The optimal temperature for heating the matrix during pressing is 160-180°C. This results in the release of lignin from rapeseed straw, which also acts as a binding agent. Furthermore, it enhances plasticization, accelerating relaxation processes, reducing friction coefficients, lowering the energy intensity of the process, and enabling the achievement of the required briquette quality.
Pressing at a heating temperature of 160-180°C leads to stable production of rapeseed straw briquettes with a moisture content of the initial material of up to 16%. In the case of particle size reduction to 20 mm, briquetting can be performed without adding a binding agent.
The most acceptable initial moisture content of the briquetting mass is 8-12%. Higher moisture results in fluffy briquettes, while lower moisture leads to less density. With moisture exceeding 16%, intensive steam formation occurs in the pressing chamber, which is dangerous during operation.

The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
