Spent grains from microbreweries are mostly formed by malting barley (or malt) and suitable for a further valorization process. Transforming spent waste to raw materials, instance, in the production of nontraditional flour, requires previous drying A natural convection solar dryer (NCSD) was evaluated as an alternative conventional electric convective (CECD) dehydration process local microbrewe...

Olive Mill Wastewater (OMWW) treatment is considered to be one of the main challenges that Mediterranean countries face. Although several procedures and technologies are mentioned in the literature, these techniques have several disadvantages or have been limited to laboratory pilot validation without posterior industrial projection. Recently, an advanced environmental friendly strategy for the...

thin layer drying behavior of sweet lemon slice was experimentally investigated in a convective type dryer and the mathematical modeling performed, using thin layer drying models given in literature. drying experiments were conducted at inlet drying air temperatures of 40, 50, 60, 70 and 80 ?c; two slice thicknesses of 3 and 6 mm, and, at one drying air velocity of 0.5 m/s with three replicatio...
