A direct fired natural gas air heater provides the energy required for evaporation, with a maximum inlet air temperature of 1,200 0 F. Atomization for our small scale spray dryers is provided by either a pressure nozzle, or a two-fluid nozzle. Nozzle configuration can be co-current (spray down) or mixed-flow (spray up).

Abstract. The influence of inlet and exit air temperatures (160-200 and 80-100C, respectively) on the spray drying of mandarin oil was evaluated by using a three-level factor design. For optimization, dryer evaporative rate, volatile oil retention, and microencapsulation efficiency were considered as response variables.

Features. HITN (High Inlet Temperature) refrigerated compressed air dryers are compact with highly efficient heat exchangers, no internal mesh to foul. Heat exchange efficiency is increased by creating helix flow paths in counterflow arrangement. The two-stage separator/filter removes condensed oil ad water over a wide range of flows.

For higher production, you run with a higher inlet temperature. There are three other factors which can limit the inlet temperature: Powder ignition temperature . Many powders will ignite and burn if they are exposed to temperatures above their ignition temperature. If this occurs in a spray dryer, it can result in a fire and possibly an explosion.

For most-efficienty use of your spray dryer, use the Auto-Stop mode to prevent the machine from running empty. Small samples. ... Maximum inlet temperature: 120 C; Maximum sample throughput (H2O): 150 ml/h; Minimum partical size: 200 nm; Maximum partical size: 5 …

inlet air temperature was less than 5%, the determination coefficient being close to 0.96. The economic value of this system is obvious, because it is easy to anticipate the spray drying param-eters by using a controller integrating the water availability of the concentrate and certain thermody-namic parameters.

Jun 01, 2012 Yet the dryer spec sheet showed that the unit was only designed for a maximum inlet temperature of 105F. As you can see from the chart below, 105F compressed air holds 24 grains of water vapor per cubic foot or about 1.5 grams. At 118F a cubic foot of air will holds about 35 grains. Thirteen degrees above the inlet temperature design ...
