  • 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 ...

  • A study on the exergetic analysis of continuous textile dryers

    This study deals with the exergetic analyses of the continuous textile dryers consisting of a stenter and a conveyor belt dryer. The exergy destructions in each of the components of the overall system are determined for average values of experimentally measured parameters. Exergy efficiencies of the system components are calculated to assess their performance. The effects of varying exhaust air ...

  • 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 ...

  • Do You Know How to Use the Sawdust Dryer Correctly

    The wood chips dryers are always used to dry the biomass materials to the suitable moisture of about 15% to make wood pellets. The workers must know the operation regulations of the dryers otherwise you may not achieve the desired outcome because of some minor details. 1, After the ...

  • Influence of spray dryer parameters on exergetic performance of microencapsulation processs

    Exergy analysis of fish oil microencapsulation process by spray drying was carried out. The process was performed on a mini–spray dryer and skim milk powder was used as the coating wall material. The drying experiments were conducted to find the effects of inlet drying air temperature, drying air mass flow rate, feed mass flow rate, and spraying gas mass flow rate on inlet exergy, outlet exergy, ...

  • Performance evaluation of exhaust air recirculation system of mixed mode solar dryer for drying of onion flakes

    This paper deals with the performance of mixed mode type solar dryer for drying onion flakes. During the experiments, no load and full load test were conducted to find out the effectiveness to the system with or without recirculation of exhaust air. The drying and thermal efficiencies and heat utilisation factors were recorded as 21%, 74% and 31% respectively, more compared to recirculation of ...

  • 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 ...

  • Drying plastic resin pellets in injection- Molding & Extrusion processes case study

    Application Moisture concentrations are measured in the dry purge air used to remove moisture from a hopper containing plastic resin pellets used in injection-molding and extrusion processes. Problem Moisture contaminates the plastic resin pellets causing several quality problems in the finished plastic products. Moisture causes clear ...

  • Biological Dryers Improve Performance/Economics of Biomass Projects

    Greater use of biomass for power generation is often constrained by the high moisture content of these fuels. As water contert increases, heating value drops, hampering the economics of the biomass utilization. Dryers can be used, but most traditional dryer desigrs reqjlrea large amount of energy to dry the biomass and are expensive to maintain and operate. As a result, much of the organic waste ...

  • The Fatal Flaw in Dew Point Measurement for Injection Molding

    Dew-point measurement is a common and important metric in the plastic drying process. A good dew point meter can tell you whether your dryer is working normally or if it’s in need of repair. Dew point meters do this by measuring the humidity in the air that flows through the dryer. What dew point meters won’t tell you anything about, however, is how much moisture is actually present ...

  • Indirect solar drying kinetics of sheanut ( Vitellaria Paradoxa Gaertn.) kernels

    An indirect solar dryer was tested for drying sheanut kernels. The influence of tray distance from heat source, airspeed and particle size on drying kinetics was investigated. Optimum drying air parameters obtained in the dryer were airspeeds of 1 and 1.4 m/s and a temperature of 40°C–45°C. Sheanut kernel slices dried entirely in the falling rate period. Drying rate decreased with increase in ...
