Technical Description
Working off two internal rotors which are independently operated by motor and pneumatic actuator, the Rotodoser allows the user to hit an accuracy up to ± 10 grams (depending on product characteristics).
Customers set a ‘target weight’ on the Rotodoser HMI controls which are connected to weigh scales. If the target weight is 25kgs, then the vane operated by the pneumatic actuator will perform the bulk dosing part, bringing it to 24kgs.
Using two rotors allows the user to reach a target weight quickly, where just the small interior rotor would take far longer. Once the valve has dosed to 24kgs, the smaller interior rotor will take over and bring the user to their target weight.
