Twin-Rotor Paddle Mixer
The Bepex Hydramix is a twin-rotor paddle mixer designed to mix and hydrate during long residence times without particle degradation. The Hydramix offers residence times ranging from a few minutes to hours. Despite extended residence times, the Hydramix provides thorough mixing while preventing particle damage.
Low rotor speeds result in low-shear operation to provide thorough mixing while preventing particle damage – even during long residence times.
The Hydramix operates in a continuous fashion, with capacities ranging from 5-100ft3/hour. It’s capable of high-production rates while still offering residence times in excess of 60 minutes.
Fully intermeshing twin rotors provide exceptional mixing while keeping free of buildup, important for handling difficult transition phases during reaction processes.
Our self-cleaning design features close tolerances between the mixing paddles and the vessel walls to reduce material buildup and inefficient mixing.
By reducing material build up, the Hydamix provides more consistent operation, greater mixing capabilities, and reduced maintenance.
Mixing Energy Control
Mixing speed and paddle angle can be adjusted separately and independently of conveyance requirements to vary the amount of mixing energy imparted to the material.
Low-speed, gentle handling protects particle shapes. Low shear and mixing intensity minimize particle fracture typically seen in high-speed mixers.
Liquid injection nozzles can be located anywhere along the length of the unit for precise control and optional staged addition.
The unit is jacketed and the rotors can be heated to promote reactions or to prevent sticking.
How does it work?
The Hydramix consists of twin intermeshing paddle rotors operating at different speeds in a covered trough.
Feed powder is continuously introduced while liquid is simultaneously injected through nozzles positioned along the vessel to match the mixing or reaction requirements.
Paddle rotors mix the powder and liquid while pulling it through the trough. The vessel can be heated to promote reactions or to prevent sticking.
Due to continuous rather than batch operation, the Hydramix is capable of high-production rates while still offering residence times in excess of 60 minutes.
Despite long residence times, the Hydramix’s low rotor speeds and adjustable paddle angles result in a low-shear operation that provides thorough mixing while preventing particle damage.
The combination of gentle handling, self-cleaning, precise residence time control, available heated jacket and rotors, and customizable liquid introduction, makes the Hydramix an economical and efficient option for carrying out controlled reactions and solids hydration. For example, it is often used in reacting various feed supplements for introduction as nutritional additives in animal feeds.
