In the process of using a centrifugal Spray Dryer, a good operation method will be able to better enhance the drying effect. As a user, a corresponding inspection is required before use.
The main inspection contents are as follows: First, it is necessary to check and confirm that the sealing material of the centrifugal spray Dryer pipe connection is good, and then connect it to ensure Do not let unheated air enter the drying chamber. Second, check carefully that the door and observation hole are closed and there is no air leakage. Third, we must also pay attention to check the bottom of the cylinder and the cyclone at the end of the cyclone when the installation should check whether the seal off, so as to avoid leakage when used. At the same time, it is necessary to check the lubrication conditions of the fan, the blower, and the atomizer when starting the machine. In addition to these basic inspections, before starting the centrifugal spray dryer, it is necessary to check whether the adjusting butterfly valve at the inlet of the centrifugal fan is open. Do not close the butterfly valve when the current is allowed so as to avoid forgetting to open it when it is dry. , otherwise it will damage the electric heater and the air inlet duct, which must be paid full attention.
In addition, check and confirm that the connecting pipe of the feed pump is connected properly. The rotation direction of the motor and the pump is correct. When the feed pump is used, it cannot be idled, and the stator is damaged. It must be filled with water before it can be opened. When it is finished, please close it in time. Drop feed pump. Finally, after starting the equipment and gradually starting to run, the on-site staff should pay attention to observing whether the rotation of the electric atomizer on the top of the drying chamber of the centrifugal spray dryer is correct and whether the water cooling is smooth so as not to damage the atomization head. The above is mainly for everyone to introduce the contents of the inspection before the operation, while the equipment in the process of operation, we must also standardize the operation. First open the centrifugal fan, then open the steam valve, and check for leaks. If it is normal, the cylinder can be warmed up. Remember that in the drying process, the inlet air temperature should be increased as much as possible under the dry quality permitting conditions. Then switch blower and oscillator, when the drying chamber inlet temperature reaches 160 ~ 180 °C has stabilized, open the centrifugal nozzle, until adjusted to the appropriate requirements. The concentration of the feed liquid should be configured according to the nature of the drying of the feed to ensure that the finished product has good flowability after drying.
