20 Head Multihead Combination Weigher 1.6L/2.5L – Multi-Channel Medium Hopper 130bpm High Output Automatic Weighing Machine
20-Hopper Full-Range Multi-Component Blending Weighing Master | 10–1500g Universal Medium Volume High-Throughput Production Solution
This flagship industrial multihead weigher is equipped with 20 independent medium-sized weighing buckets, supplied with dual interchangeable 1.6L / 2.5L medium hopper specifications. It achieves a sustained maximum production speed of 130 bags per minute, paired with reliable X(0.5) weighing accuracy and 0.1g minimum scale division. As all-range universal precision weighing and filling equipment, the 20 independent weighing channels bring two irreplaceable core strengths: ultra-high continuous single-item packaging throughput, and ultra-flexible proportional quantitative weighing for multi-component mixed raw materials, perfectly covering small sachets to large family pouches across food, pet food, pharmaceutical, hardware and chemical industries. Unlike 10/12/14/16-head medium capacity models, its 20-channel layout provides the largest pool of weight combinations, greatly reducing weight deviation while supporting simultaneous blending of multiple different granular ingredients without pre-mixing.
Product Introduction
The 20 head combination weigher with 1.6L and 2.5L medium hoppers is developed as a universal all-scenario weighing flagship, built for factories with diversified product lines that switch frequently between single granular goods and multi-ingredient mixed blends. It supports four mature industrial control systems: TIANJI / TIANPING / TIANZUN dedicated weighing modules and industrial PLC intelligent control platform, matched with 7-inch / 10-inch color touch HMI that stores dozens of independent material formulas for one-click quick switching.
The biggest differentiation point of this high speed multihead weigher against other medium-capacity multihead weighers lies in its 20 fully separated weighing units. Abundant combination permutations simultaneously deliver two production advantages: 130bpm top-tier stable running speed for mass single-product packaging, and precise proportional matching for assorted mixed materials such as mixed nuts, seed blends and multi-formula pet food pellets. The dual medium bucket sizes balance adaptability for compact dense granules and irregular lumpy snacks within the 10–1500g weighing range. This heavy-duty automatic weighing machine is the top-tier upgrade choice for comprehensive food processing plants, pet food manufacturers, hardware fitting packagers and multi-product snack factories aiming to unify small and medium packaging production lines with one single piece of equipment.
Why Choose This 20 Head Combination Weigher (1.6L / 2.5L Medium Hoppers)
① 20 Independent Medium Buckets: Dual Advantages – 130bpm Peak Speed & Flexible Multi-Ingredient Proportion Weighing

Working Principle of 20 Head Multi-Channel Medium Capacity High Speed Multihead Combination Weigher
This 20 head weigher is equipped with 20 fully independent medium-capacity weighing buckets, each equipped with separate vibration feeding trays to support separate feeding of different raw materials. Single or multiple types of granular/bar-shaped raw materials are evenly distributed into each hopper via the top multi-channel central feeding system. The built-in TIAN series weighing core or PLC control system synchronously collects real-time weight data from all twenty buckets, then runs dual-mode intelligent calculation:
Single-item packaging mode: Automatically select the bucket group closest to the target weight for fast synchronous discharging, supporting stable 130bpm maximum throughput;
Multi-ingredient mixed blend mode: Independently match the required weight proportion of each raw material from different weighing channels, then discharge all required ingredient groups simultaneously for uniform mixed-blend filling, specially adapted for factories with diversified mixed snack and pet food production demands.
Compared with all 10/12/14/16-head medium capacity multihead weighers, the extra four independent weighing channels multiply available weight combination values and support separated ingredient feeding, realizing simultaneous high-speed single-product mass packaging and accurate multi-component proportional weighing — exclusive technical advantages for comprehensive multi-product processing factories.
