Drying of arenca (triportheus Magdalenae): influence of salting on dried and wet stack
Abstract
The aim of this study was to determine the influence of salting on dried (SD) and wet stack (WS) during the drying of arenca from determining mass transfer coefficients (Kc ) and diffusivity (Da ). Moisture content and NaCl of arenca sheets according to time was determined during salting SD and WS. Data were analyzed in the PHARM/PSC® version 4 program, and the least significant difference test (DMS) was applied when a difference between the averages was observed. These data are used in a mathematical model for determining mass transfer coefficients and diffusivity. It was used for this equation concentration in function of time and position for an infinite slab of thickness 2L. It was observed that the best conditions of transfer were made for salted with SD. Depending on the type of salt no significant effects were found (p <0,05) on the transfer of water and NaCl, but whether as long as it remains in the sample solution (p <0,05).Downloads
