Vertical Colloid Mill
Colloid mills work on the rotor-stator principle: a rotor turns at high speeds (1400 2800 RPM). These mills allow for adjustment of the gap between the (coned) rotor and stator with wider settings providing a slightly coarser product texture if required. In some cases for in-line mills with high viscosity product a pusher pump may be required.
Colloid mills can work with chunkier, more viscous and more sticky products that comparable standard in-line emulsifiers. Some of the more tricky application were colloid mills come in to their own include - mincemeat (for pet food), peanuts (to become peanut butter), chillis (for sauces), almonds (for almond milk).
The internal forces evenly disperse, emulsify, smash and homogenise various semi-liquids, liquids and emulsions.
