Process research on using carbon dioxide when tableting instant products and dry mixtures of plant components

The aim of the study is to investigate the process of using carbon dioxide in tableting instant products and dry mixtures of plant components. An experimental setup was used to study the tableting process. The study was conducted on powdered and dry ground mixtures of food products with the same dispersion value. For the studies, plant materials prepared and processed in accordance with the requirements of pharmacopoeial articles were used. The names of plants were selected based on the condition of differences in anatomical and morphological structure. Such plants were: chamomile, St. John's wort, and safflower leuzea. A dry mixture of instant jelly was used as a powdered raw material. All samples had the same initial moisture content of 6 %, which was preliminarily determined on an A&D ML-50 moisture meter, and then the samples were placed in a desiccator. The components were weighed using M-ER-122 ACF-150-005 laboratory scales. Solid CO2 was obtained by throttling compressed gas from a cylinder precooled to minus 30 ºC. Compression testing of materials and the process of molding the tableted product were performed on a PM-MG4 universal hydraulic testing machine. The paper describes the methods of experimental studies on the sublimation of tableted and crystalline carbon dioxide, presents the results of our own experiments on tableting an instant drink and dry mixes of safflower leuzea, common St. John's wort, and chamomile using solid CO2. The nature of particle bonding in tablets. A new method for tableting instant products and products obtained by tableting dry mixes of plant products using solid CO2 is presented. The obtained tablet forms were studied. The results of the disintegration process of tablet forms and the influence of the tableting method on the extraction of target components are presented.
