Sanitary bulk bag filling system
In operations where sanitary conditions are paramount, such as dairy and food processing plants, ensuring accuracy and hygiene in bulk bag filling is crucial. These industries often face challenges like cross-contamination and maintaining cleanliness standards while efficiently packaging products in bulk quantities.

Ensures hygienic and accurate bulk bag filling
The RELCO® Bulk Bag Filler by Kovalus Separation Solutions is engineered for sanitary applications, offering stability and precise control for every bag filled. Built to 3A standards and USDA guidelines for dairy equipment, this filler is made from robust stainless steel for corrosion resistance and durability. It features a PLC/HMI interface, pneumatic systems, and motor starters housed in UL-listed NEMA 4 stainless steel enclosures. An integrated scale controller with fixed-load cell set ensures accuracy. The design allows for effortless cleaning and maintenance, with tool-free disassembly and easy access provided by a stainless steel platform. It also includes a rotating bag loop hanger system for single-point operator interface, facilitating the loading of empty bulk bags. Adjustable hangers accommodate different bag widths, and the filler head can be quickly exchanged for various bag neck sizes. Sanitary air is used to expand the bag through a bulk bag-inflation venturi and HEPA filter, minimizing the risk of bridging from partially collapsed bags. A hydraulic scissor lift maintains a stable flat bag bottom and adjusts to bag sidewall lengths between 45 and 72 inches. Additional features such as a pneumatic thumper reduce product buildup, and an automated dust collection control valve manages air displacement and dust during bag changes.
