The MT16 micro-ingredient feeder includes design upgrades to increase accuracy and performance, including a feature allowing interchangeable feeding modules. The interchangeable twin to single screw feed modules provide versatility to handle a broad range of materials from powders to granular materials. The overall feed rate capacity is from 0.02 dm³/hour to 27 dm³/hour. The new design allows for extended screw profiles, with a smaller overall footprint, allowing for closer discharge dimentions. It is ideal for multi-ingredient cluster arrangements. The unit is easy to take apart, clean and maintain, with a totally enclosed weight sensor and drive motor with improved higher torque for handling difficult materials.
