Introduction

 ^{During spray drying of feed liquid, tremendous energy and mass transfer occur within an extremely short time. Concentrated liquid drops leave the atomizer at the speed of 100-200m/s. Most moisture is removed from the retarding travel of liquid drops; and during this travel, fog drops lose initial velocity, and are carried away by dry air. Small liquid drops have 90% moisture evaporated at 0.5m away from the atomizer; while about 1.5m travel is required for big liquid drops.
In the full process of drying, the temperature of liquid drops is between the surrounding air temperature and wet bulb temperature; and after atomization, the temperature of liquid drops will rise to be slightly higher than the wet-bulb temperature immediately. The evaporation of moisture from the surface of liquid drops starts from the constant-speed drying stage. At this stage, liquid drops are still fluid, and moisture in liquid drops is easy to move from inside to the surface of the liquid drops, maintaining the surface moistened.
At the later drying stage, the moisture content reaches a critical value, liquid drops lose the characteristic of fluid and become wet solid, and encrustation forms on the surface. In such a case, steam is produced because the received heat is bigger than the momentum of moisture movement, so the internal pressure further rises and makes the shell break. This stage is featured by the sudden appearance of a humidity gradient in the radial direction of liquid drops. Moisture passes through the inside of particles and diffuses outwards, and the drying rate begins to drop. Therefore, this stage is called as retarding stage.
Spray drying has been widely applied in each industry in recent years due to the removal of moisture within an extremely short time.
Its process flow is as shown below:
Clean air after filtration is heated by means of the heat-transfer oil heat exchanger to about 250°C with 310°C heat-transfer oil provided by a natural gas heat-transfer oil furnace and is then sent with a blower fan to the orifice-plate hot air distributor on the top of the drying tower. The hot air distributor distributes hot air evenly and makes hot air flow from top to bottom of the tower in parallel. Dried feed liquid is sent with a plunger pump into the pressure spray gun on the top of the tower, and becomes innumerable conical fog drops under the function of the pressure spray gun. Fog drops and hot air flow down inside the tower, transfer heat and mass quickly, become dry powder, flow together with tail gas from the bottom of the tower to the built-in fluidized bed on the bottom of the tower prior to continuous drying until the moisture is up to standard, and then, enter into the packing bag from the central discharging pipe. The fluidized bed dries the air and collects tail gas; the air-dried and tail gas collected will flow into the cyclone cluster, then through a draught fan, they will access the wet scrubbing tower for dust removal prior to being evacuated. The powder lot at the bottom of the cyclone cluster enters the top of the tower for condensation and granulation by means of a compressed air delivery system, and the excessive power lot is sent to the wet scrubbing tower for dissolution and recycling. Refer to the flow chart for details.}

FEATURES

1. Rapid drying speed. The surface area of the material will be enlarged greatly when liquid raw material is atomized and 95% - 98% of water can be evaporated instantly in the hot airflow. The drying time only needs to take several seconds. This dryer is especially suitable for heating-sensitive materials.

2. The finished product is a ball granule with a uniform size. Its fluidity and solubility are good. The quality and purity of the product are very high.

3. Depending on the characteristics of the raw material, the dryer can use hot air to dry or use cool air to granulate.

4. Simple and stable operation. The control system is convenient which is easy to realize automatic operation.
