That one is called:
*Octagonal Seasoning Drum / Flavour Mixing Machine*
Also called: *Chips Seasoning Mixer, Drum Seasoning Machine, or Tumbler*
*How it works:*
1. After you have fried and removed oil from chips (in the first machine I showed you), you pour the chips inside that big octagonal drum.
2. You add your flavour - like salt, masala, tomato, cheese powder, etc.
3. You switch on, the motor on the side rotates the whole drum slowly. Because it's octagonal (8 sides), the chips tumble and mix very well, so every chip gets flavour equally.
4. After mixing, you tilt it and it pours out the tasty chips ready for machine
