Centrifugal spray dryer granulator

Description

Manufacturer\'s direct sales DZL****0 centrifugal spray drying granulator The spray technology of the centrifugal spray dryer refers to the use of spraying methods to disperse the material in the form of droplets in the hot gas flow. The fully contacts with the hot gas, completing the heat and mass transfer process in an instant, causing the solvent to quickly evaporate into a gas, achieving the purpose drying. This technology can save on evaporation, crystallization, separation, and crushing unit operations, allowing for continuous and automated production with stable operation. Theugal spray dryer uses this drying method, with a large contact surface area between the gas and solid phases, short drying time, usually ***0 seconds suitable for drying heat-sensitive materials. The product obtained from the drying has good performance, small particles, good fluidity, and solubility. The disadvantage is the dryer has a large volume, low heat transfer coefficient, leading to low thermal efficiency and high power consumption. What are the operating knowledge of the centrifugal dryer? Below we introduce the pre-use inspection and operating procedures so that everyone can correctly operate the centrifugal spray dryer and have a further understanding of it 1. Pre-use inspection (1) Whether the pipeline connections are equipped with sealing materials and whether the sealing performance is good. (2 Whether there is any脱落of the sealing ring and whether there is any air leakage during use. (3) Check the lubrication of the fan, shut-off, and atomizer to ensure good lubrication. (4) Whether the regulating butterfly valve at the fan inlet is in the open state. (5 Whether the inlet pump\'s connecting pipeline is well connected, and whether the motor and pump\'s rotation direction is correct. (6) The inlet pump must not dry to avoid damaging the stator. It should be turned off promptly after use. (7) Whether the rotation direction of the atomizer is correct and the water cooling is unobstructed. 2. Operating procedures (1) Start the fan, then start the electric heating, check for air leaks, and if not, proceed to preheat the cylinder. Make sure to close the valve at the discharge port during preheating. (2 When the inlet temperature of the drying chamber reaches **0℃***0℃, open the centrifugal spray head to make it rotate. 3) When the spray head reaches the highest speed, open the inlet pump to add liquid material. Start with a small amount and gradually increase it to the appropriate. The concentration of the material should be determined based on the drying properties of the material. (4) During the drying process, pay attention to the exhaust and ensure it remains constant. (5) After drying is complete, collect the product and proceed to subsequent operations
