Matko S. Improvement of the process of the adsorption refining of apple juice and its coupagou.

Dissertation is devoted to the improvement of the process of refining apple juice and its coupagou by natural domestic adsorbents. An effective and low-cost adsorbent, paligorskit, has been selected. The process of its moistening by apple juice has been explored. The kinetic dependences of changes in concentration of pectin substances in juice and in paligorskit have been obtained, coefficient of diffusion of pectin substances in the pores of the adsorbent have been determined. Adsorption capacity of paligorscit in relation to high molecular connections, heavy metals and microorganisms, when refining apple juice, has been proved, mechanisms of processes, which here take place, have been suggested and founded. The apparatus-technological schemes of the adsorption refining of juice and its coupagou by paligorscit have been improved, their economic efficiency has been grounded. For the purpose of determining the sizes of sediment apparatus, the regularities of the sedimentation of the hovering particles,after the coupagou is being processed by paligorscit, have been studied. The mathematical models of refining apple juice and its coupagou by paligorscit, which give the possibility to process to conduct the process in the optimum mode, have been developed. Keywords: adsorption refining, high molecular connections, moistening, ecological safety, coupagou, sedimentation, paligorskit, natural dispersion minerals, stability, factionalism, apple juice.
