25/40 kW RF Dryer

Electromagnetic fields at radio frequencies can produce a heating effect in some non-

conductive or dielectric materials. Radio frequency or dielectric heating has been in use for over

fifty years, and has become an important technique in many industrial processes. The alignment

of molecules of the dielectric materials changes rapidly at the radio frequency field. Since heat

is defined as a motion of molecules, increasing the molecular motion generates heat. The

electromagnetic energy heats the desired material directly without affecting the surrounding

structure or the air within it. The entire material of product is heated uniformly without being

dependent on the thermal conductivity of the material. Dielectric heating is fast, uniform,

energy efficient and clean.

Water is very receptive to

dielectric heating; Radio

Frequency (RF) dryers are

ideal for a host of drying

applications. A wide range

of materials including food,

natural and synthetic

textiles, papers, plastics,

agro and pharmaceutical

products can be processed

using RF dryers

Acoustic sounding for probing the atmosphere is a well-

established technique for getting vital atmospheric parameters

which are useful for environmental monitoring. These acoustic

Doppler radars are popularly known as SODARS (Sound Detection

and Ranging). This system will normally transmit sound energy in

pulses in zenith and two or more orthogonal tilted directions.

The weak received signals, back scattered from the atmosphere

due to temperature inhomogeneity, are further processed. The

total height of the system is around 2m above ground.

Special and customized design of an acoustic barrier cum enclosure for the acoustic sounder

using marine plywood, open cell acoustic foam (polyurethane), vinyl sheet and glass wool

The acoustic antenna for the SODAR consists of 52 acoustic transducers arranged in 8x8

array (3 elements are removed from each corners) which are fixed on a square Bakelite

sheet. This antenna is placed at an angle of 20 degree from vertical. The reflector plate was

placed in front of the antenna assembly in such a way that, the signal emitted/received from

the transducer array will get reflected from the reflector plate to form a beam pointing

towards zenith direction.

Field Programmable Gate Array (FPGA) based re-configurable DAQ (Data Acquisition) card

(National Instruments PXI 7831R) is used for online 8 channel acoustic signal generation,

program developed using LabVIEW™ FPGA software.

The new re-configurable Labview based system has given lot of flexibility for system

operator. The system has enabled for remote operation or control through Wi-Fi/ Ethernet.

This eliminates the need to go to the field for the operators. Operators can use the system

from the remotely located laboratories.
