Client: A major Canadian agricultural cooperative
Industry: Grain and legume processing; consumer goods packaging
Outcome: Achieved stable weighing accuracy of ±1g and increased production output by over 300%
Located in the heart of Canada's legume-growing region, the cooperative had long supplied high-quality red beans in bulk bags to global food processors, establishing a solid reputation in the B2B sector.
However, the client keenly recognized the limitations of a business model reliant solely on bulk commodity trading—specifically, limited product value-added potential and the absence of brand premiums. To break through this growth bottleneck, the cooperative decided to implement a strategic shift: processing its premium red beans into own-brand retail packages for direct sale to end consumers.
This decision was significant but brought unprecedented challenges:
Retailers impose strict legal compliance requirements regarding net weight; traditional manual weighing methods struggled to maintain a consistent accuracy of ±1g for 250g bags while operating at high production speeds.
Retail packaging demands far higher standards than industrial bulk packaging regarding seal appearance, zipper usability, and package integrity.
Entering the supply chains of major supermarket chains required adherence to rigorous food safety standards, necessitating enhanced hygiene assurance during the packaging process.
Tapping into the retail market required mass supply capabilities; the cooperative needed a packaging system capable of supporting large-scale production with the potential for future capacity expansion.
After careful evaluation, the client selected a fully automatic red bean zipper bag packaging machine from Anhui Hengkang Machinery. This integrated system offers several core technical advantages:
The equipment features a 14-head multi-head weigher, ensuring stable weighing accuracy of ±1g for each 250g bag of red beans. This level of precision virtually eliminates product loss, ensures every bag meets its labeled weight, and resolves measurement compliance issues at the source.
The system’s automated functions—bag picking, zipper opening, filling, and sealing—enable precise handling of pre-made stand-up zipper bags. The equipment automatically performs the following actions: picking up bags one by one, opening the zippers, filling them with precisely weighed red beans, and creating a secure, neat seal above the zipper to ensure a professional and attractive appearance.
The main body of the equipment is constructed from food-grade SUS304 stainless steel. Its structural design prioritizes hygiene and cleanliness, facilitating easy maintenance and meeting the high food safety standards required by major retailers.
The entire packaging workflow—from bag picking and opening to weighing, filling, and sealing—operates fully automatically. This significantly reduces the need for manual intervention, ensuring production consistency and reliability.
This new red bean zipper-bag packaging machine is more than just a piece of production equipment; it is a strategic engine driving the rise of the cooperative's own retail brand.
The new packaging’s consistent high quality, adherence to safety standards, and professional appearance were key factors in securing a long-term supply contract with a major Canadian supermarket chain. Leveraging the stable supply capabilities provided by the automated packaging line, the cooperative successfully broke into retail channels that were previously out of reach.
The precise control of the automatic weighing system saves the cooperative a substantial amount of product loss caused by overfilling each year. This factor alone has significantly boosted overall profit margins.
