Modernization of operating chicory factories using continuous pulsating extractors

Chicory roots are a valuable source of inulin and other healthy nutrients. The most common direction their industrial processing is instant chicory powder production. Extraction the main process in Conventional extraction methods, which include maceration, percolation screw extractor, have number significant drawbacks, including high capital operating costs, low quality resulting extract, complexity repairing equipment, short overhaul life, etc. purpose present study was to assess technical feasibility increasing efficiency through using continuous pulsating extractors (CPE) developed by Ingehim company, non-stationary, countercurrent mode interaction raw materials with extractant incorporated. Testing engineering solutions implemented CPE carried out at pilot unit (PPU). For extraction, roasted crushed (5–20 mm) from one factories were used. ratio : water during 1 4.5, 1.5–2.5 times lower than conventional extractors. A temperature (up 85°C) combined shorter time hour) may help retain more nutrients as compared methods. results PPU under these conditions confirmed yield water-soluble solids 98%) without additional grinding. scheme for modernization factory equipped equipment having feed capacity 400 kg/h proposed CPE. 3D images shown. comparative assessment energy consumption different methods given. indicate capability extracting chicory, decrease up 3.6 total specific obtaining kg Low costs determine prospects existing or creation new energy-efficient factories.
