CIRO, HÉCTOR; OSORIO, JAIRO ALEXANDER  y  CORTES, ELKIN ALONSO. DETERMINATION OF THE ISOSTERIC HEAT TO PLANTAIN PULP (musa paradisiaca) BY SORPTION ISOTHERMS. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.156, pp.127-134. ISSN 0012-7353.

For sorptional data to be useful in simulation and design of storage and drying systems, they must be represented by equations valid in the conditions usually found in industrial practice. Using the modified Chung-Pfost model and fitted by desorption the net and total isosteric heat of plantain pulp was evaluated. The net isosteric heat decreased with increasing moisture content ranging from 1670 kJ/kg (5%.d.b) to 215 kJ/kg (26%.d.b) where the better goodness of fit was presented by polynomial and power-law models.

Palabras clave : Physical properties; moisture content; isosteric heat.
