  • Performance of a solar dryer using hot air

    A solar dryer for drying herbs and spices using hot air from roof-integrated solar collectors was developed. The dryer is a bin type with a rectangular perforated floor. The bin has a dimension of 1.0 m!2.0 m!0.7 m. Hot air is supplied to the dryer from fiberglass-covered solar collectors, which also function as the roof of a farmhouse. The total area of the solar collectors is 72 m2. To ...

  • Precipitator Solves Dryer Problem

    Plum Creek Manufacturing, Columbia Falls, Montana, installed a PPC Industries electrostatic precipitator to solve a direct fired dryer dust plugging problem. The electrostatic precipitator was installed in a very congested area and the project had to be done so the dryer was off-line a minimal amount of time. Plum Creek personnel relocated existing equipment, poured concrete footings, ran all of ...

  • Performance investigation of the drying of parsley in a tray dryer system

    The performance of a tray dryer system for the parsley drying process was assessed using energy and exergy analysis methods in this study. The drying temperature ranged from 40°C to 60°C, while the drying air velocity varied from 0.5 m/s to 1.5 m/s. The higher temperature and lower velocity led to higher exergy and energy efficiencies. The exergy efficiency value for the overall system on a ...

  • Industrial Dryer Drives Fast Economic Development of Central China

    In recent years, China has been greatly influenced by the global economic crisis, and the engineering mechanical industry encounters winter season which caused some companies to stop production or even close down; and the dryer machine manufacturing industry also suffers a lot. Drying generally refers to process in which the heat air makes water in the materials evaporate and brings it away, and ...

  • Experimental investigation of the performance of the solar tunnel dryer for drying aonla pulp

    This article presents the critical design specifications and field performance of an improved solar tunnel dryer for drying aonla plup. The dryer consists of an ultraviolet stabilised semi-transparent polythene sheet of 200-micron thickness with loading capacity of 1 ton of aonla in a batch. Drying of aonla is mainly carried out by traditional method of sun drying, but the use of improved solar ...

  • Energy and exergy analyses of drying of apricots in a rotary solar dryer

    This paper presents the energy and exergy analyses of the drying process of apricots in a rotary column cylindrical drying (RCCD) cabinet. For these purposes, all stages of the drying process, considered as a steady-flow thermodynamic system, were analysed. Using the first law of thermodynamics, energy analysis was carried out to estimate the amounts of energy gained from solar air collectors and ...

  • Further Application of the Semenov Model to Evaluate the Possibility of Spontaneous Combustion in Tumble Dryers

    Previously, Jones applied the Semenov boundary conditions and thermal explosion theory to the problem of predicting spontaneous combustion of laundered clothing in a commercial tumble dryer. This problem is revisited here with a modification of the limiting assumptions made in the previous work. Relaxation of the limiting assumptions (i.e.,considering air flow through the drum) demonstrates that ...
