Foodmax Machines supplied two 14-head multihead combination weigher systems to a coffee processing company in Vietnam. The project supported automatic weighing for roasted and green coffee beans across several retail bag formats.
The customer handled coffee beans for different sales channels and packaging orders. Its line needed to process both roasted coffee beans and green coffee beans. Pack formats ranged from small retail bags to 1 kg commercial packs. Frequent changes between bag sizes created extra adjustment work for operators. During busy periods, manual weighing slowed the packaging process. It also made weight control more difficult across different coffee bean batches.

Three Challenges in Manual Coffee Bean Weighing
Production challenge
Effect on the packaging line
Different bean sizes and densities
Pack weights could vary between batches
Multiple bag formats
Operators needed frequent manual adjustments
Manual weighing work
Output slowed during high-volume production
Coffee beans are irregular granular products. Even within one batch, each bean can differ slightly in size, shape, and density. For this reason, reaching a stable target weight with manual methods required frequent checking. Overfilling also increased long-term coffee bean giveaway.
The customer selected a 14-head multihead combination weigher because coffee beans require flexible and accurate combination weighing. Each weighing hopper holds a measured portion of coffee beans. The controller checks the available weights and selects a combination close to the preset target. Fourteen weighing heads offer more available weight combinations during each cycle. This helps the system approach the target weight without relying on repeated manual correction. For coffee packaging, this reduces unnecessary giveaway while supporting stable production.

Frequent adjustments between bag sizes
Saved settings for faster changeovers
Greater risk of overfilling
More consistent target-weight control
Limited capacity during busy periods
More flexible production with two systems
“Trước đây, công nhân phải mất nhiều thời gian kiểm tra từng túi cà phê. Giờ đây, việc cân tổ hợp nhiều đầu giúp công việc dễ dàng hơn nhiều. Chúng tôi giảm được chi phí nhân công và hao hụt cà phê.”
“We used to spend a lot of time checking each coffee bag. Now, the multihead weigher makes things much easier. We’ve reduced labor costs and coffee waste.” — Production Director (Vietnam)
