Investigation on the use of solar thermal energy in the agro food industry in Algeria

Abstract

Large amounts of natural gas are used by the agro food sector to produce thermal energy, often at low temperatures, for several tasks. Substituting this resource constitutes a big challenge from which the actions conducting to the energy savings have to be explored. In the present paper, we investigate the potentialities of natural gas saving in the dairy industry as a case study of the industrial sector. Next, we present the experimental results showing the potential of solar thermal energy, at low temperatures, that can be explored for the heating process using flat plat collectors.
