Powder heat transfer problem
Thread Content
Dear experts, I’m dealing with powdered starch (with a diameter of 75μm–150μm, a bulk density of 700 kg/m3, and a temperature of around 100 degrees Celsius). The processing capacity is 5 tons per hour, and I want to reduce the temperature to room temperature, which is 30 degrees Celsius. Several options have been considered: 1. A vacuum feeder that lifts the material about 8 meters. I wonder if the cooling effect is good? 2. Powder flow cooler; for more details, see the post: http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=878479. It is not clear whether this type of cooler requires regular cleaning, and its cooling efficiency is uncertain. 3. The modified linear multi-layer vibrating conveyor features a dual-cooling system; water pipes are installed beneath the bottom plate of the material being conveyed, while air currents flow above the material. Please share your opinions. Thank you first!
For fine fluid powders, we use a cooling plate device or a hollow impeller cooler
If the waste heat is not to be recovered and only cooling is required, double-shell screw conveyors as well as screw conveyors with an internal hollow shaft can be used to solve this issue; we can discuss this further if it’s convenient. 13619857965
Our company has used it; we apply it in the field of semi-coke
It was also considered to install an air pump at the middle and lower part of a horizontal mixer with a U-shaped cross-section, to force room-temperature air into the mixer, and then to remove the hot air that has exchanged heat with the material. I wonder if this would work?
The effect won’t be very good; using air as a cooling source is not as effective as using water.
It would be best if you could provide us with the production process flow and equipment layout diagram of your products, so that we can design a set of specialized equipment tailored to your setup. wangwei9540@126.com
As a manufacturer of powder cooling equipment in Canada, starch cooling may not be suitable for use, as it involves certain process parameters
For powder cooling, there is a new type of device: the powder flow heat exchanger. It requires no power source and generates no dust. If you are interested in learning more, please contact QQ770909640. Thank you.
