Title:
PROCESS AND PLANT FOR THE PRODUCTION OF MEALS CONTAINING POORLY DIGESTIBLE STARCH
Document Type and Number:
WIPO Patent Application WO2006105957
Kind Code:
A8
Abstract:
Process for treating a dietary meal containing starch, so as to make the latter poorly digestible, comprising the steps of: feeding a continuous flow of a starch-containing meal into a turbo- reactor (A) comprising a horizontal-axis cylindrical tubular body (1), provided with at least one inlet opening (5, 6), at least one discharge opening (7) for the treated product, a heating jacket (4), a bladed rotor (8) put into rotation at peripheral speeds comprised between 15 and 40 m/s, feeding into the turbo-reactor (A), cocurrently with the starch flow, a continuous and finely divided flow of a reactant consisting of a concentrated aqueous hydrogen peroxide solution, centrifuging the meal particles and the reactant against the turbo- reactor inner wall heated at a temperature of at least 100°C, with formation of a thin, dynamic, highly turbulent tubular fluid layer, reacting the meal and the reactant into the thin layer while it progresses in substantial contact with said inner wall of the turbo-reactor (A) towards the discharge opening (7), continuously discharging a flow of treated meal, having a humidity content of 30-50%, sending the flow of treated meal on to a maturation step for a time varying between 30 minutes and 24 h, at a temperature of 60-90°C, and to a subsequent drying step to bring the humidity content of the end meal to 10-16%.
