Удосконалення безвідходної ресурсоощадної технології комплексної переробки локальної рослинної сировини у багатокомпонентні функціональні матриці на основі обладнання з локальним теплопідведенням

The object of research is the process of waste-free, resource-saving processing of local plant raw materials into multicomponent functional matrices of a high degree of readiness. The problem that was solved was aimed at increasing the complexity of processing plant raw materials in conditions of minimizing secondary waste. Classical approaches to raw material processing are focused on obtaining a limited number of semi-finished products in conditions of the formation of secondary raw materials that are not fully processed, increasing resource efficiency. Heat and mass exchange equipment with intermediate coolants is used for processing plant raw materials, which leads to an increase in the cycle duration and specific costs. The concept was substantiated within the framework of improving the waste-free, resource-saving technology of processing local raw materials (Jerusalem artichoke, pumpkin, carrot, sweet potato and chaenomeles). The technology is focused on the comprehensive use of functional and technological properties of raw materials during processing on equipment with local heat supply: preliminary heat treatment is carried out in the range of 65–90°C (2–10 min) in a sectional cassette-capacitor apparatus. Concentration of the multicomponent matrix in a rotary film evaporator at a temperature of 45–65°C to a content of 30–45% dry matter. IR drying of the concentrated semi-finished product in the range of 45–60°C in a roller IR dryer. The recipe ratio: 25% Jerusalem artichoke, 30% pumpkin, 15% carrot, 20% sweet potato and 10% chaenomeles forms a multicomponent matrix with inulin, pectin, carotenoid, starch and antioxidant properties. The technology fully processes pumpkin, pectin-containing residues of chaenomeles and unpeeled Jerusalem artichoke. The difference is the comprehensive use of local plant raw materials to expand the range of functional semi-finished products and products obtained using resource-saving equipment and technological solutions.
