Leading Manufacturer, Supplier & Retailer of Convection Dryers and Adsorption Air Dryer.
Convection dryers are often used for drying solids in food technology. TheConvection Dryingcan be used to investigate and demonstrate the process of convection drying of granular solids. Four corrosion resistant removable trays are available for drying the solid. Theyare positioned in a drying channel. The trays containing the solid to be dried are exposed to an airflow in the channel. The airflow heats the solid and also removes the moisture that is released. Airflow rate can be controlled by adjusting the speed of a fan. Air temperature is controlled with an adjustable heater. The transparent door in the drying channel allows the drying process to be observed. Digital scales can be used to follow the changes in weight of the solid due to evaporation or vaporisation of moisture during operation. The air temperature and the relative humidity of the air are recorded and digitally displayed by combined temperature and humidity sensors before and after the airflow passes over the solid sample. The hand-held anemometer provided, measures airflow rate. The relevant measured parameters can be transferred directly to a PC, where they can then be further processed.
TheAdsorptive Air Dryinghas been specifically designed to enable the complex theoretical principles of adsorption processes to be conveyed clearly and comprehensibly. Moist air flows through the adsorbent (silica gel), which is placed in a transparent column as a packed bed, and the moisture is adsorbed. The adsorbent contains an indicator. The colour of this indicator shows the position of the mass transfer zone. Once the capacity of the adsorbent in this column is exhausted, the moist air is fed through a second column with regenerated adsorbent. The experimental setup allows simultaneous investigation of the adsorption process and the regeneration process for the adsorbent which uses heated air. Recordings of all relevant parameters enable both processes to be completely balanced.
