STUDY OF THE SOLAR DRYING OF BOVINE MEAT: DRYING KINETICS AND TEMPERATURE PROFILES IN A MIXED TUNNEL SOLAR DRIER

The conservation of meat remains a problem in countries with hot climates because the latter being very perishable; therefore requires adequate means of preservation to preserve its microbiological and organoleptic stability (1).Solar drying, which is already widely used, in the open air, by the populations and which is defined as being an operation which consists in extracting a quantity of water impregnating a product using as energy source solar energy, can therefore be, if well controlled from an energy and health point of view, a good solution for these countries where solar energy is abundant and where its populations do not have access to cold storage. The lowering of this content makes it possible to reduce the activity of enzymes and the rates at which undesirable chemical changes occur in order to ensure their conservation for a relatively long period or to facilitate their transformation (2).Physically, drying most often results from a simultaneous transfer of heat and mass within the product to be dried and at the interface between this product and the drying environment (3, 4, and 5).However, given the complexity of the transfer mechanisms and the diversity of the products, knowledge of the basic data, in this case the kinetic curves are necessary. Research has been done on the drying kinetics of meat (6, 7, 8, and 9) as well as its diffusion coefficient (10, 11, and 12), all of these results lead us to think that it is necessary to study experimentally and model the drying kinetics of beef, in particular for different treatments during drying.Several empirical or semi-empirical models have been developed to account for the drying kinetics and to understand the physical laws that control transfers.
