I am working on a project on vacuum drying vegetables using IR heaters. Before winter batch time was around 3 to 4 hours now it has increased to 6 hours. Any logic behind this as though the temperature drops and RH also drop so why has the time increased?
I want to remove 6% moisture in one hour from 500 kg of polyester staples, which contains 12% moisture using vacuum chamber at maximum temperature of 40´´°¨ C. Can anybody help to design vessel. I can calculate pump capacity.
Thank you. I agree with you. Particularly when molecular density is 10^18. But have you seen Brian Cox's video. A large feather is falling straight though the surface area of area is very large.
Thank you, I can not sort particles. I will try UV as suggested. However I am also looking for any...
I made experiment on "Free Fall". I made a conical hopper of 15 liter volume and a vacuum chamber of , installed hopper upon vacuum chamber of 65 liter volume. Fixed a 2.5" gate valve to discharge powder in vacuum chamber. Connected both, hopper and vacuum chamber to vacuum pump (63 cum/ hr) and...
I did a experiment. I made a vacuum chamber with a silo on the top. Also provided the butter fly valve between vacuum chamber & silo. Filled the silo with low density powder say 0.2 gm / cc. Created vacuum in silo having powder and vacuum chamber. When I dropped this powder in vacuum chamber...
