AB  - The efficient utilization of waste from food industry is possible after thermal treatment of the material. This treatment should be economically feasible and compromise the energy efficient drying process. The main goal of this investigation is to determine drying characteristics of nectarine pomace as a waste from food industry. The measurements were performed in an experimental dryer by combined conductive-convective drying method with disk-shaped samples of 5, 7, and 10 mm thickness and 100 mm in diameter at the air temperatures of 30, 40, 50, 60, and 70 degrees C, hot plate temperatures of 50, 60, and 70 degrees C and air velocity of 1.5 m/s. The drying curves were compared to a few semi-theoretical mathematical models. The Logarithmic model showed the best correlation. On the basis of experiments, it is determined that the drying process takes place in a falling rate period and it is accepted that the main mechanism of moisture removal is diffusion. The effective coefficient of diffusion was determined using experimental results by calculating the slope of the drying curves. Drying time and equilibrium moisture are determined for each experiment. Analysis of drying curves showed that the conductive-enhanced drying method reduces drying times and increases the diffusivity coefficient. The character of drying rate curves for conductive-enhanced drying was analysed and compared with pure convective drying of nectarine pomace.

AB  - The paper deals with the manufacturing costs of shell and tube heat exchangers with concentric helical tube coils. The most common correlations for calculating prices of shell and tube heat exchangers found in accessible literature were tested using the market data for a comparison and they have shown significant deviations. A new correlation for estimating prices of heat exchangers with concentric helical tubes (when the shell is made of carbon steel and the helical tube of copper) was determined in the following form: C-in = 614.S-hts(0.627)

AB  - Laboratory scale tunnel dryer for convective-conductive drying of food was designed with the ability to regulate the drying parameters by controlling the thermo-mechanical properties of the humid air and the temperature of the materials by convective-conductive methods, as well as precisely adjusting the fraction of recirculated air in the drying process. The dryer is fully automated, with the ability to operate according to temperature or humidity parameters. Automation and control of the process and drying parameters was achieved by frequency regulation of the forced air flow system, proportional-integral-differential (PID) temperature drying regulation and ON / OFF regulation of air humidity (agent), as well as PID regulation of the heating of materials by a conductive mechanism. All regulated sizes are measurable with the ability to connect to an external computer for data collection.
