چکیده
Drying is one of the main technological processes plant raw materials processing in production dry food products and powders from them. Convective drying most widespread method vegetable materials, which accompanied by high energy costs for process. Increasing efficiency colloidal capillary-porous a 2-zone chamber dryer occurs due to use coolant recirculation between zones installation thick-film heating electric elements. The proposed design element its technical characteristics are presented. Studies kinetics were carried out on created energy-efficient with installed Reducing process possible through manufacture 2 sections elements (21 pieces each). Installing this heater allows you save electricity consumption up 30 %. study particular potatoes pumpkins. intensity limited quality material, so at low temperatures. Material control assessed recoverability organoleptic indicators after drying. results experimental studies unit showed that increase significantly end when moisture evaporation decreases. heat per kilogram evaporated analyzed order determine optimal time. Energy corresponds effective type convective dryers. Bibl. 20, Fig. 8.

Energy Efficient Process Heating: Managing Air Flow
Much energy is lost through excess air flow in and out of process heating equipment. Energy saving opportunities from managing air flow include minimizing combustion air, preheating combustion air, minimizing ventilation air, and reconfiguring openings to reduce leakage. This paper identifies these opportunities and presents methods to quantify potential energy savings from implementing these e...
متن کاملFree convection in a 3D chamber with local cooling and heating
This paper modeled heating air of a room through examining free convection in a 3D chamber. The chamber had cold and hot sources with Tc and Th temperatures, respectively. Its other walls were adiabatic. This study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. To conduct the st...
