the best price Vanilla powder Spray Dryer

Product Description

The spray drier is widely used in the liquid shaping technology and in the drying industry. Particularly it is suitable for producing powder, granule or block solid product from solution, emulsion, suspending liquid and pumped paste liquid.

The working of spray dryer is as follows: Fresh air after filtering and heating, enters into the air distributor at the top of dryer.Then the hot air enters into the drying chamber. The liquid of raw material is pumped in through diaphragm pump, be atomized into tiny droplets. Through the very short time of contacting the hot air, the materials can be dried into the finished products.The wasted air and fine powder will be collected through collector at the bottom of cyclone.The tower body also equipped with observation door, sight glass, lamp-house and so on.

During spray drying of feed liquid, tremendous energy and mass transfer occurs within 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 surrounding air temperature and wet bulb temperature; and after atomization, the temperature of liquid drops will rise to be slightly higher than wet bulb temperature immediately. The evaporation of moisture from surface of liquid drops starts from constant-speed drying stage. At this stage, liquid drops are still fluid, and moisture in liquid drops is easy to move from inside to surface of liquid drops, maintaining 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 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 sudden appearance of humidity gradient in radial direction of liquid drops. Moisture passes through the inside of particles and diffuses outwards, and drying rate begins to drop. Therefore, this stage is called as retarding stage.

♦ Quick drying speed. In the hot air stream, 95% to 98% of moisture can be evaporated immediately.
♦ It is especially suitable for drying thermal sensitive material.
♦ The product made by the machine has good uniformity, fluidity and high quality.
♦ The productive process is simple and the operation control is very convenient.
♦ For liquid containing 40-60% of damp (for special material, may be 90%), it can be dried to powder product through drying one time. After dried, it is not necessary to crush and sieve. So it reduces productive procedure and raises the purity of product.
