What is flour tanker trailer
The vertical flour tank trailer is used for transporting bulk flour materials. Its tank is a horizontal cylinder and a number of vertically inverted cone bins. The minimum angle between cone bins and horizontal surface is greater than the resting angle of the flour materials. The materials flow to the discharge port by gravity and pneumatic conveying.
Why do we need a flour transport trailer to transport flour?
Flour is a kind of powder milled from wheat, which is divided into special first-grade flour, special second-grade flour, and common flour according to processing precision. With different grades, the granularity and bulk density of flour is different. As we research, some flour mills use horizontal flour tank semi-trailer to transport flour, and the residual amount can reach 3 0 0 ~ 500kg usually. Due to the large fluidized bed area of a horizontal flour tank semi-trailer, flour is inconvenient to clean it up, and the flour interspersed between the fluidized air belt is even more difficult to clean it up. The residual flour is easy deteriorates after staying in the tank for a long time, which is a great danger to health. While a vertical flour tank semi-trailer can realize zero residual.
Composition
Bulk flour tank trailer is an important vehicle for transporting flour from mills to flour processing enterprises. It is an important carrier in bulk flour transportation. It is mainly composed of chassis and upper part, which can be simply divided into five major parts: chassis system, transmission system, tanker, piping system, accessories, etc.

Working Principle
The working principle is to drive the air compressor (pump) by the truck power. The compressed air is sent into the air chamber in the sealed tank so that the powder on the fluidized bed in the air chamber are suspended into the fluid state when the pressure in the tank reaches the rated value. Then open the discharge valve, the fluidized material flows through the pipe, which belongs to fluidized discharge. The sealed tank is with simple structure, and the flour can be well stored during transportation.
Features of bulk transportation compared with bagged transportation
into the bulk trucks from the warehouse of flour mill and transported to users, such as food factory. The transportation is realized by pneumatic conveying technology. It avoids the loss of spillage when packing, handling, and dumping. When users use the flour, the flour is sent directly to the food producing line.
Compared with bagged transportation, bulk flour transportation saves packing process in flour mills, loading and unloading process in circulation, and stacking and discharging process in final users, simplifies operation, reduces labor intensity, and saves a lot of labor.
More importantly, the bulk transportation saves a lot of packaging materials, avoiding the loss of flour when filling and dumping bags. And in the process of manufacturing flour bags, plastic granules, garden loom, coating, and others make pollution to the environment. Eliminating these problems of bagged flour in the process of circulation brings huge economic benefits for bulk flour transporters. 
Panda flour tanker safety use precautions
- 1. When loading, fulfilling the tank is forbidden, and we should leave some space for flour grain expansion.
- 2. When loading, we should not mix debris into the tank to avoid blocking the discharge pipe and affecting the discharge speed and residual rate.
- 3. When unloading, if the air compressor with abnormal sound, depress the clutch pedal, turn off the engine, and close solenoid switch of the extractor. Start working after the fault is removed.
- 4. When unloading, pay attention to the change of pressure gauge. The operator should not leave the scene to avoid abnormal high pressure.
- 5. The tank should be kept dry everyday for anti-caking of flour.
- 6. In maintenance, we should prevent parts from falling and knocking, to avoid deformation, bumping, scratches, etc. Parts must be clean before installing.
- 7. When the air compressor is working, nobody should stand at the side of the air compressor.
- 8. When speeding up, don’t press the accelerator too hard. Please use even force.
- 9. Remember not to use the external air source to exhaust.
- 10. When the compressor stops working for other reasons in the process of decompression, close the inlet ball valves at the front and rear bins, and then open the external air source; after a while, close the external air source and open the inlet ball valves.
- 11. Special attention: after the first unloading, make sure to check the bolts and U-shaped bolts of the pivot point and tighten the bolts one by one; afterwards, check the bolts regularly, and if loose is found, tighten it.
- 12. When tank pressure is too high, open the safety valve, and the exhaust valve to reduce pressure.
- 13. If there is water into the tank body, release water through the two water release valve at the bottom of the tank in time. If the fluidized bed canvas is wet, it should be replaced at once to avoid material caking on it.
- 14. If abnormal conditions happens, stop unloading. Firstly close the discharge valve, and then opening the exhaust valve to release the pressure in the fluidized bin.
Maintenance of Flour tanker trailer
- (1) To ensure the cleanness of the materials in the tank, the dirt inside the tank and at the discharge port should be cleaned regularly. The first few times the tank is put into use, it is recommended that the users inspect the inside of the tank each time before use.
- (2) In order to prevent the fire, the vehicle is not allowed to be used when the fire prevention and anti-static device fails, the camping road system or the tank leaks, the electrostatic mopping tape fails or the ground wire is not connected. If the mopping tape wears out, the pressure plate should be loosened and the mopping tape pulled out a section to ensure that the tape is well pressed to touch the ground.
- (3) When tank is freezing, it is not allowed to use fire heating to thaw. We should drive the vehicle to the warm room or thaw by steam heating. (Note: improper heating is strictly prohibited)
- (4) It is strictly forbidden to hit any part of the tank with metal objects in case of sparking and fire.
- (5)During loading and unloading, even if the working time is very short, the operation must be carried out according to the requirements of the working site to ensure the safety of loading and unloading.
- (6)Keep the air inlet and exhaust of the ventilation valve smoothly. If you use the pump to unload the material, you must first open the manhole cover on the filling port cover to prevent the tank from being deformed due to the excessive flow of the pump.
- (7) The driver should know how to use fire extinguishers, which should be maintain and replace in time.
- (8)When the tank and piping system seepage, leakage, absolutely do not weld the tank if it is with pressure. First the material should be unloaded cleanly, then release the tank pressure, open the manhole cover and all valves, place the flour tank trailer after a period of time, finally drive the vehicle into the open field before welding.
- (9) In order to extend the service life of the vehicle, it should be loaded with the rated loading capacity, and should not exceed the maxi weight of the original vehicle. If the road condition is fine, the weight can be increased appropriately, but shall not exceed the maximum total mass allowed by the original chassis.
- (10) Double or multi-bin tank, each bin should be loaded at the same height, to prevent the biased load on the whole vehicle causing unnecessary damage.
From which aspects to buy a qualified flour tanker?
