∴ CONDENSER & HEAT EXCHANGER

We are mostly dealing Shell and tube Heat exchanger.

Shell and tube heat exchangers consist of a series of tubes which contain fluid that must be either heated or cooled. A second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required. A set of tubes is called the tube bundle and can be made up of several types of tubes: plain, longitudinally finned, etc

Fixed tube sheet Shell &
tube type

Shell and tube heat exchangers consist of a series of tubes which contain fluid that must be either heated or cooled. A second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required.

Floating tube sheet type

A fixed tube sheet heat exchanger is the cheapest because of the ease of fabrication. This heat exchanger requires periodic cleaning, replacement of tubes etc. and inside of the tubes can be easily cleaned by mechanical means (by forcing wire brush or worm )and cleaning of the tubes from outside require removal of the tubes bundles from the heat exchanger, in addition to the above-cited difficulty many heat exchangers are provided with removable tubes bundles.

Fin tube heat exchanger

Finned tube heat exchangers have tubes with extended outer surface area or fins to enhance the heat transfer rate from the additional area of fins. Finned tubes or tubes with extended outer surface area enhance the heat transfer rate by increasing the effective heat transfer area between the tubes and surrounding fluid. The fluid surrounding finned tubes maybe process fluid or air.

INDUSTRIAL DRYERS

There are following types of industrial dryers we are manufacturing.

• Atmospheric tray dryer (ATD)
• Vacuum tray dryer (VTD)
• Fluid bed dryer (FBD)
• Rotary cone vacuum dryer (RCVD)
• Rotary vacuum peddle dryer (RVPD)
• Ribbon Roster cum dryer

ATMOSPHERIC TRAY DRYER (ATD)

The basic working principle of this incredible machine is the continuous circulation of hot air. In the tray dryer, moisture is removed from the product that is placed in the tray by a forced convectional heating. This dryer is also known as Cabinet Dryer, Electric dryer, Air dryer, Tray dryer etc. This dryers are classi¬fied as direct dryers, where hot air (at near atmospheric pressure) is used to supply the heat to evaporate water or other solvents from the product.

VACUUM TRAY DRYER (VTD)

Vacuum drying is a viable technology that has been used successfully for many years in the pharmaceutical industries.

Another advantage of drying materials in this way is a less damaging drying process. Some materials can experience problems at high temperatures, such as developing hard, leathery crusts from heat ex-posure during the drying process. Vacuum drying tends to retain the integrity of the original item without damaging it with heat. It is also possible to recover the precipi¬tated moisture collected during the drying for further use.

FLUID BED DRYER (FBD)

Fluid bed dryer (also called Fluidized bed dryer) is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules.

The equipment works on a principle of fluidization of the feed materials. In fluidization process, hot air is introduced at high pressure through a perforated bed of moist solid particulate. The wet solids are lifted from the bottom and finger bag is suspended in a fluidized shell to trap the material. Heat transfer is accomplished by direct contact between the wet solid and hot gases. The vaporized liquid is carried away by the drying gasses. Sometimes to save energy, the exit gas is partially recycled.
