Osmotic dehydration of cassava bagasse (Manihot esculenta) and its effect as pretreatment on the efficiency of convective drying

The cassava bagasse is an agroindustrial residue from the cassava starch industry which entails concerning environmental challenges. High moisture content and hydrophilic nature make it difficult to apply conventional drying efficiently. Osmotic p i o e s os y m dehydration (OD) is evaluated diectly in this research, and takn as a pretreatment to convetive drying (OD-Drying) of this (Biodegradati n modeling of sludge bioreactors of total petroleum hydrocarbons weathering in soil residue with hypertonic NaCl solutions between 30% and 60% OD and between 5% and 20% in OD-Drying, using rates of 3 to 5 d di t ) g solution/g sample, with an air velocity of 1.5 m/s and at 40(degrees) C. OD alone reduced cassava bagasse moisture in 67.25 %, while edinaM no, S. e hoa C.A u L. Aguilera zq .

Found results show that OD improves convective drying of cassava bagasse, providing benefits in its post-industrial handling Gonzalez y M GutierrezRojas such as mitigation of the environmental poblem associted with it, contributing this way to the sustainable development of the 259 Crecimiento, sobrevivencia y adaptacion de Bifidobacterium infantis a condiciones acida starch industry that can also be applied to other agroindustrial residues.
