Solar Cabinet Dryer 500

SCD 500 - a novel and eco friendly way to address the needs of small scale food processing industries. The salient features include:Hygienic drying.No color degradation due to UV rays.Uninterrupted year round operations with bio gas or LPG backup. Lower running costs hence higher saving.Description of DrierCasing (Drying chamber) : The drying chamber is made of double walled fabricated casing with 50 mm PUF insulation. Inner wall of casing is made of SS 304 and outer wall with M.S. painted finish.Size of chamber : 5000 L x 1500 W x 2900 HTrays : Perforated SS 304 sheets or SS wire mesh – size 600 x 900 x 25Quantity - 162 Nos (27 Nos in each trolley with 6 trolleys.)Heating : Hot water from solar calorifier tank is circulated inside the chamber into two heat exchang-ers made of SS 304 finned tubes. The water from the calorifier tank will also be heated by LPG as a back up arrangement.Air Circulation : Two Axial flow fans provides the air circulation inside the chamber. The fans are reversible in direction and are made of fiberglass cast Aluminium impellers driven by 3 HP ,class H insulated Three Phase motors. Fans rotation will be reversed periodically to change airflow through the trays.Inlet and Outlet air dampers : Motorized dampers actuated manually or automatically by sensing the humidity inside the chamber.Humidity and Temperature sensors : Installed inside the chamber and connected to automatic cli-mate controller to actuate the fans, dampers and hot water pumps. The automatic temperature climate controller is optional and the operation can be manual also.Inlet air quality : The air can be de-humidified by regenerative type dehumidifiers to supply dry air into the chamber. The efficiency of the drier will be enhanced by the dehumidifier. In humid atmo-spheres, the dehumidifier will be ideally suited to improve the efficiency of the drier.SPECIFICATION OF SCD 500 CABINET DRIER1Size of the chamberLength - 5000 mmWidth- 1500 mmHeight- 2900 mm2Maximum temperature70 deg.
