Sanitary bulk bag unloader for powdered products
Efficiently manage powder discharge with enhanced dust control and streamline bag handling in your production line using a robust, customizable bulk bag unloader designed for challenging materials.

Efficiently Unloads and Transfers Bulk Powders
The RELCO® Bulk Bag Unloader from Kovalus Separation Solutions stands out for its adaptable design tailored for USDA sanitary applications. It’s engineered to handle a wide range of powder materials, ensuring efficient unloading with minimal dust. The system incorporates a sanitary receptor tube with dual pneumatic cylinders for precise spout clamping, enhanced by a vibrating bag pan to promote consistent powder flow. Its robust construction supports a 2,500-pound capacity, accommodating various bag sizes. Suitable for industries like dairy, food, and beverage, it facilitates the handling of end-products like milk powder, whey protein, and baking mixes. Optional features such as a hoist and monorail system, dual-bag massagers, and loss-in-weight batching support integration into existing production lines. Constructed from stainless steel, it meets stringent sanitary requirements while ensuring easy cleaning and maintenance. This unloader not only improves throughput but also maintains operational efficiency with features like a dust collection port and manually-operated iris valve for controlled changeovers. Customization options and engineering support are available to meet unique processing needs across diverse industrial sectors.
