Dry Ingredient and Powder Handling


Efficient dry ingredient and powder handling underpins the success of many processes and requires systems which are specifically designed for your product requirements and unique applications. Powder processing is challenging and must be designed to maximize flowability and consistency, and must account for moisture content, storage time and electrostatic charge.

BMI partners with the most innovative equipment suppliers to offer turnkey solutions for process efficiency, accuracy, product consistency, safety, and ease of use. Our systems are designed to minimize water usage, energy usage and waste.
