Industry Pain Points
·Uncontrollable formula ratio deviation and compliance risks: Traditional pre-mixing process causes severe material layering due to differences in particle size, density and shape between 4 materials, leading to inconsistent ingredient ratio in each package. This violates food labeling regulations in Europe, North America and other regions, bringing huge product recall risks and brand reputation damage.
·High material breakage rate and raw material loss: Fragile materials such as freeze-dried fruits and vegetables, crispy nuts are easily broken, crushed and scratched during conveying and weighing in ordinary equipment, with breakage rate as high as 5% or more, resulting in serious raw material waste and poor finished product appearance.
·Poor material compatibility and unstable weighing accuracy: 4 materials often have huge differences in fluidity, brittleness and bulk density. Ordinary single weighing system cannot balance the weighing accuracy of all materials, leading to frequent overweight/underweight issues and unstable product quality.
·Severe cross-contamination and food safety risks: Traditional mixed production uses shared conveying and weighing channels for different materials, leading to flavor cross-contamination, color mixing and microbial cross-contamination risks, which cannot meet the strict requirements of FDA, BRC, HACCP and other international food safety certifications.
·Heavy manual dependency and low production efficiency: Traditional multi-material production requires multiple sets of independent equipment and extensive manual intervention in material feeding, weighing, mixing and packaging, leading to soaring labor costs, frequent human errors, and production efficiency 3-4 times lower than automated lines.
·Long formula changeover time and poor flexibility: Switching between different formulas, material ratios and packaging specifications requires long debugging time on traditional equipment, resulting in frequent unplanned downtime, unable to adapt to the fast-response demands of multi-SKU and small-batch customized production.
·Uneven mixing and poor customer experience: Traditional process cannot achieve uniform mixing of 4 materials in each individual package, leading to inconsistent taste and experience when consumers open the bag, reducing product repurchase rate and brand loyalty.

·The multihead weigher operates in exclusive 4-mix mode, completing synchronous high-precision weighing of the 4 materials at the same time. The 4 weighed materials fall through the downward sloping chutes, and are temporarily stored in the discharge hopper blocked by the lifting piston cylinder. The multihead weigher sends a ready signal to the packaging machine and waits for the discharge request signal.
·After receiving the discharge signal from the packaging machine, the piston cylinder opens synchronously, and the 4 weighed materials are discharged uniformly into the bowl-type elevator. The bowl-type elevator smoothly lifts the fully mixed 4 materials into the feeding hopper of the 520 VFFS machine.
·The 520 VFFS machine automatically completes bag forming, material filling, airtight sealing, date coding and finished bag cutting in one continuous process.
·The sealed bagged finished products are transported from the packaging machine outlet to the rotary collecting table through the finished product conveyor for sorting, inspection and stacking, realizing fully automated continuous production of the whole line.
