Construction of the spray dryer. The construction of a spray dryer is shown in Figure 1.1. It consists of a large cylindrical drying chamber with a short conical bottom, made up of stainless steel (the diameter of the drying chamber ranges between 2.5 to 9.0 meters, and the height is 25.0 meters or more).
Spray-drying is a technique based on the transformation of a fluid into a dry powder by atomization in a hot drying gas stream that is generally air [1].The spray-drying process consists of four fundamental steps: (i) atomization of the liquid feed, (ii) drying of spray into drying gas, (iii) formation of dry particles and (iv) separation and collection of …
Pumping: the slurry is pumped at high pressure to the spray dryer; 3.2 Atomization. In order to ensure a very fast drying it is necessary to atomize the influx of liquid in very small droplets. This increases a lot the exchange surface where humidity can leave the particles. This atomization is done thanks to 1 or several nozzles. ...
Spray drying is a one-step continuous unit operation that employs liquid atomization to produce droplets that are dried to individual particles when moved in a hot …
Schematic of high pressure jet spray dryer (HPJ-SD), where CSM = condensed skim milk, TS = total solids, LP = low pressure, HP = high pressure. The spray dryer used to build this prototype was a lab-scale spray dryer (Niro Mobile Minor, Model 68, Denmark) that regulated its airflow using a single motor-driven fan at the fines outlet. …

This is typically accomplished by using a high-pressure nozzle or rotary atomizer. The goal is to create a large surface area for efficient drying.
spray drying is measured by the amount of water evaporated. Evaporation is defined as the difference between inlet and outlet temperature, or T, in the dry-ing air. The larger the T, the greater the capacity of the spray dryer. The goal in optimizing a spray dryer's capacity is to increase T by raising the inlet tempera-
