Overview of equipment advantages of jiangsu Bohong upper exhaust pressure spray drying tower  

1) Energy saving: Because the air return chamber of the upper exhaust tower is the high negative pressure area of the tower on the upper part, in the process of evaporation, high negative pressure evaporation will reduce the evaporation temperature, and the reduction of temperature will save steam and energy.  The upper exhaust tower only consumes 2.8-3.0kg of steam to evaporate 1kg of water, saving 8-10% of steam.  

2) Saving construction investment: with the same specification of equipment, the height of the upper exhaust tower is 5-7m lower than that of the lower exhaust tower.  

3) Good product quality: the particles of upper exhaust spray drying tower powder are uniform, and the larger particles and smaller particles are less.  Because the dry area of the powder is high negative pressure area, the drying of the powder is low temperature drying, making the powder in a variety of vitamins less damage, protein is not denaturated.  In addition, due to the powder in the drying process of heating time is relatively short in the high temperature region, so that its color, granularity, tonality are better.  

4) Easy cleaning: the tower body structure is simple and convenient to manufacture.  Because the column and cone of the tower are directly connected, the Angle connection is too smooth, there is no dead Angle when cleaning, after opening the tower door can be easily cleaned each part in contact with dust.  

5) Reduce the amount of sewage and save energy to reduce labor intensity: the lower exhaust tower tower can not form a ring wind curtain, tower wall hanging powder is serious, every day to brush the tower.  Brush tower increase material loss and waste a lot of hot water.  It not only consumes energy but also increases the amount of pollution discharged.  But dry mixed flow and the flow of the droplets is the constant speed drying period for downstream, slow down period for mixed flow row of wind, the wind reached the bottom of the form 180 g, make the drying of material and air separation, the wind in the rapid upward movement in the tower wall form a large circular air curtain, formed the annular air curtain, dry tower control of the tower wall hanging powder phenomenon, can wash a tower over ten days,  This reduces the amount of pollution discharged, saves energy and reduces labor intensity for workers.
