Fermentation Spray Dryer Tower Experimental Procedure Before the fermentation broth spray dryer tower is operated, check whether the sealing material is installed at the pipe joints and then connect them to ensure that unheated air is not allowed to enter.
Check that the door and viewing window are closed and check for air leaks.
The bottom of the barrel and the pollinator at the bottom of the cyclone should be checked for leaks before installation. The pollinator can be tightened before it is removed, and the pollinator must be cleaned and dried.
Check that the direction of rotation of the centrifuge is correct.
Whether the regulating butterfly valve at the outlet of the centrifugal fan is open, do not close the butterfly valve, otherwise the electric heater and the air inlet pipe will be damaged. This must be paid full attention.
Is the connection pipe of the feed pump connected, and the direction of rotation of the motor and pump is correct.
Place the spray head on the top of the drying chamber to prevent it from leaking.
The fermentation broth spray dryer tower runs first to open the blower, then turn on the induced draft fan, adjust the air supply and the draft fan air conditioning valve, and check whether there is air leakage in each connecting pipe, door and quick-cleaning cleaning port, and set the in and out. Wind temperature value, if normal, can be turned on for electric heating, preheating the barrel body, because the hot air preheating determines the evaporation capacity of the drying equipment, and the inlet air temperature should be increased as much as possible without affecting the quality of the material to be dried.
When the inlet and outlet air temperatures reach the set value during preheating, the atomizer and the feed pump are sprayed first, and the test run before the equipment sample is performed, and the parameters are appropriately adjusted.
After adjusting the parameters and all the normal conditions, the material can be added, and the amount of material to be discharged should be adjusted in real time until the adjustment is made to the good state. The concentration of the feed solution should be based on the temperature at which the material is dried.
The temperature and humidity of the dried product depend on the exhaust air temperature. It is extremely important to keep the exhaust air temperature constant during operation. Depending on the amount of feed, the feed amount is adjusted stably.
The humidity of the product is too high, which can reduce the amount of feed to increase the outlet temperature, and the humidity of the product is too low, and vice versa.
The dried product is collected. In the polluter of the bottom of the tower and the lower part of the cyclone, the pollinator should be replaced before it is filled. When the pollinator is replaced, the upper butterfly valve must be closed before proceeding.
The fermentation liquid spray dryer tower shutdown and cleaning first converts the material liquid into a clean water spray for 5-10 minutes. After collecting the product, the electric heating is turned off. When the exhaust air temperature is lower than the set value, the feed pump is turned off, and the inlet air temperature is lower than 70. After the degree, the atomizer, the induced draft fan, and the blower are turned off.
Open the drying tower cleaning door to observe the condition inside the tower, clean the dry powder adsorbed on the tower wall, rinse the main tower with a high-pressure water gun, remove the pipeline cyclone, and install the pipeline and cyclone to the original position after the Zui.
Check that the door and viewing window are closed and check for air leaks.
