Hollow blade dryerIt can indirectly heat or cool paste like, granular, powdered, and slurry like materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature calcination. The special wedge-shaped stirring heat transfer blade in the equipment has high heat transfer efficiency and self-cleaning function of the heat transfer surface. Hollow blade dryer is an efficient and multifunctional heat conduction drying equipment widely used in various industries such as chemical, pharmaceutical, food, and feed.
The common faults and solutions of hollow blade dryer are as follows:
1. Blade damage:
Reason: Poor quality of propeller blades, improper use, mixing of hard substances in materials, long-term wear, etc.
Solution: Regularly check the condition of the blades, repair or replace damaged blades in a timely manner, ensure that there are no hard substances in the material, and operate the equipment correctly.
2. Low production:
Reason: Insufficient steam pressure, poor mixing effect, slow material operation speed, etc.
Solution: Adjust the steam pressure, increase the spindle speed, check and clean the wall sticking or scaling on the heating surface.
3. High moisture content:
Reason: Short material retention time, excessive material filling, and high material humidity.
Solution: Adjust the material quantity, reduce the spindle speed, and control the material humidity.
4. Rotary joint leakage:
Reason: Damaged sealing gasket or dynamic seal.
Solution: Check and replace damaged gaskets or dynamic seals.
5. The condensate cannot be completely drained:
Reason: mismatched steam and drain pressure, improper or damaged drain valve selection.
Solution: Adjust the steam and drain pressure, and replace the appropriate drain valve.
6. The device cannot start or runs unstably:
Reason: Power supply issue, motor malfunction, transmission system problem.
Solution: Check the power supply and motor to ensure that the transmission system is functioning properly.
