“…The number of droplets is smaller to make the heat energy easier to form due to the droplets that have turn to vaporize. The temperature inside the spray dryer is higher than the previous research [14]. The droplets flow from the nozzle to the bottom of the spray dryer dragged by gravitational force and the spray energy.…”

Spray dryer comes at the end of the processing line since it is a critical step in monitoring the quality of the final product. It has certain advantages such as rapid drying rates, a wide range of operating temperatures and short residence times. This research focuses on the effect of inlet air temperature in the spray dryer chamber. The result from previous studies has shown that the increment of the inlet air temperature has caused the dying rate to increase. From the simulation, we have identified the performance in the spray dryer with different inlet air temperature as the parameter. The higher the inlet air temperature, the less the number of incomplete particles inside the spray dryer chamber, the more the success of the drying particles. The most optimized condition of inlet air temperature inside the spray dryer chamber from different parameters was identified as 225 K after the analysis on the results of simulation data. The main impact of this study is to increase the efficiency of drying particles inside the spray dryer chamber via computational fluid dynamics. In conclusion, researchers should concentrate more on the feed inlet air temperature of spray drying for future analysis because it plays an important role that can influence the impact on droplet conversion.

“…After the salt wash process, salt drained until 30% water content and then put on 50 microns white fine transparent wrapping cloth before dewatering process. The dewatering process by centrifugal hydro extractor was conducted at different dewatering times (10,15,20,25, 30 minutes). The rotational speed was maintained at 750 rpm.…”

“…To reduce the cost of production, necessary to adapt the effective salt drying technology. However, drying is one of the most energy-consuming in industries and has its advantages and disadvantages [15]- [17]. The selection of drying technology is essential to produce better salt quality at an economical price.…”

The salt quality was studied by dewatering methods such as centrifugal hydro extraction, fixed bed dryer, and rotary drum dryer. The effect of different salt particle sizes was also analyzed. The centrifugal hydro extractor is found to be effective when reducing the high-water content of salt and suitable for reducing water content after the salt wash stage. Fixed bed dryers produce lower water content than rotary drum dryers. A water content lower than 1% can be achieved using fixed bed dryers. Finally, all dewatering methods such as centrifugal hydro extractors, fixed bed dryers, and rotary bed dryers are suitable for salt production methods. Reduced salt particle size from 30 to 60 mesh also improved the drying performance.

The present work aims in evaluate the installation of an equipment of spray drying, by psychrometry technique, analyse the power sources consumption and relates with the productivity of the equipment, by energy auditory. This work consists in comparing the evaporation capacity of a 750 kg/h of water spray dryer and the amount of water that comes from atmospheric air, where the equipment consumes 160 kWh and 80 kg of LGP/h. Therefore, this work demonstrates that to project a spray dryer it must be analysed these water mass values in atmospheric air and be contemplated a dehumidifier in order to prevent so significant and different losses in different periods of the same day.
