| Description Of Drier |
| Casing (Drying chamber) : The drying chamber is made of double walled fabricated casing with 40 PUF insulation. Inner wall of casing is made of SS 304 and outer wall with GI sheets with painted finish. |
| Size of chamber : 3030 L x 1050 W x 455 H |
| The chamber is self standing on support legs. |
| Trays : Perforated SS 304 sheets or SS wire mesh – size 600 x 900 x 30 Quantity - 10 Nos (2 Nos in each stage) |
| Movement of Trays : The tunnel drier has 10 trays moving in one direction from one end to the other end of the drier on a conveyor system. The hot air generated from Solar air heater panel is made to pass through the tunnel in such a manner, that the air passes through the material kept on trays. The air movement direction changes from top to bottom and bottom to top in each stage. This gives an effective utilization of the heat and air for a complete and uniform drying of materials. |
| Air heater Collectors : Each air collector is of size 2 M x 1 M and 6 collectors can be arranged in parallel / series configuration as per availability of space. The duct of PVC pipes takes the hot air to the chamber through a centrifugal blower. |
| Backup heating : There is an electric heater bundle of 6 KW kept in the air flow path to give back up heating when the temperature rise is not adequate in the solar collectors. Alternatively a heat exchanger heated up by hot water generated by a gas geyser can be used. |
| Electric Control System : The blower will have on / off control, the electrical heaters can controlled automatically by a temperature controller. The temperature can be measured in two or three points in the tunnel. |
| Time of drying and output : The time of drying and specific weight of each product varies considerably. For eg: 5 Kg of raw grapes can be loaded in each tray and therefore for grapes this dryer can take 50 Kg capacity on a wet basis. |
