The utility model discloses when using, thick soybean milk after the concentration passes through the inlet pipe and gets into high-pressure spray gun, and the soybean milk is 60-80 atomizing angle and spouts in the spray drying tower with vaporific, hot-blast through the air intake enter into the tower in, hot-air carries out abundant heat exchange with the vaporific material of spouting in the tower, and high temperature makes moisture evaporate rapidly, becomes likepowder granule with thick soybean milk. Moisture and air (wet wind) that evaporate behind the heat exchange are through 180 degrees gyrations, discharge through the air outlet at the top, and the material becomes powdery particle and falls into spray drying tower lower part, gets into the fixed bed through the toper discharge gate, and the powder on the fixed bed can be delivered to the fluidized bed through the wind about 70 ℃, and this stage provides preliminary cooling effect for the powder. The fluidized bed has a multi-stage fan to continuously cool the powder and convey the obtained base powder out.
The ultrafine powder obtained by spray drying enters a cyclone separator through an air outlet along with wet air, the cyclone separator separates the ultrafine powder from the wet air, the separated ultrafine powder enters a spray drying tower through a re-aggregation pipe at the top of the spray drying tower and is bonded with a material sprayed into mist at a feed inlet by a high-pressure spray gun for re-aggregation, so that the particle size is increased, and the yield of the ultrafine powder is reduced.
The utility model discloses an air outlet is last air exhaust at the top of spray drying tower, compare with airing exhaust down, the utility model has the advantages of it is following:
1. the soybean milk powder has good color and flavor: because the preheating and constant speed period of spray drying are both carried out at the upper part, the surface temperature of the soybean powder is lower than that of lower exhaust air after the soybean powder freely falls to the lower part, and the color and the flavor of the soybean powder are favorably kept.
2. The bean powder has uniform particles: the larger particles and the smaller particles are less, and the bean powder has good mixing performance because the heating time in the drying process of the bean powder is short relative to the high-temperature time of the lower exhaust tower.
3. Powder does not adhere to the tower wall: the process of spray drying in the upper air exhaust tower is that the constant-speed drying period is downstream, the speed reduction period is mixed-flow air exhaust, the bean powder forms 180-degree large rotation in the tower along with the wind, so that the particles are separated and fall into the lower part of the tower body in the rotation, and the micro powder enters the cyclone separator along with the wind for secondary separation, so that the powder is rarely adhered to the wall and the top of the tower.
4. The time for brushing the tower is prolonged: the spray drying tower can continuously run for 5-7 days, and no sticky powder exists on the top and the wall of the tower.
