This compact three-channel dual-feeding automatic quantitative filling machine serves micro-dose health supplement trial pack factories, compound spice mini-sachet production lines, organic seed sample packaging workshops, instant solid beverage small trial bag facilities and food pigment micro filling plants.
Complete Product Overview
The horizontal compact 3-head screw vibration linear combination weigher fitted with three sets of interchangeable 0.3L/0.5L mini anti-bridging hoppers is customized for small and medium food manufacturers focusing on small-batch mixed-formula ultra-micro 1–30g packaging of granules, lumps, ball-shaped particles and free-flow fine powder. It supports dual optional control systems: basic MCU or industrial PLC, matched with external touch HMI, pre-stored dedicated operation formulas for corn kernels, sesame seeds, block-shaped spices, round pill granules and ultra-fine seasoning powder.
Its core differentiated competitive advantage against all multi-head linear weighers is patented screw-vibration dual feeding system: each lane combines adjustable-speed screw propeller for powder & lump materials + low-amplitude vibration tray for sliding granules & ball particles, perfectly solving feeding blockage problems of mixed heterogeneous materials that single vibration or single screw feeders cannot handle. Three-channel parallel feeding reduces equipment floor space greatly compared to multi-head models, while horizontal single-layer fully open compact frame enables rapid hopper swap and full disassembly deep cleaning without dead corners. All material contact surfaces are polished food-grade 304 stainless steel with half-transparent dust-proof protective cover for direct observation of internal mixed material feeding state. The whole machine adopts integrated heavy-duty compact frame and height-adjustable anti-slip support legs to offset three-lane combined micro vibration, net weight 300kg with mini overall outer dimensions, occupying minimal workshop area, becoming the cost-effective compact three-lane dual-feeding weighing equipment for small-batch mixed micro-dose trial sachet packaging lines.
Exclusive Three Independent Screw-Vibration Dual Feeding Lanes
Three fully separated dual-mode feeding & high-sensitivity micro weighing assemblies
Each lane integrates variable-speed screw feeder + low-amplitude vibration tray, paired with high-precision micro load cell and interchangeable 0.3L/0.5L mini hopper, working independently; single lane material jam will not shut down the whole machine, cutting downtime loss during small-batch mixed micro material processing shifts.
Dual flexible micro-batch production operation modes
Mode 1: Unified screw rotation speed & vibration amplitude for all three lanes, stable uniform micro-dose output for mass single-material trial sachet production;
Mode 2: Separate screw speed, vibration intensity and target weight for each channel, realize three different raw materials mixed one small bag packaging for multi-ingredient health supplement trial packs, compound mixed spices and assorted seed sample pouches.
Dedicated three-lane dual-feeding weight calculation logic offsets mutual micro vibration between three mini hoppers, maintaining consistent X(0.5) ultra-high precision during long-hour synchronous feeding of mixed lumps, hard balls and ultra-fine powder.
Interchangeable dual-volume mini hopper design
0.3L mini hopper for 1–15g ultra-tiny micro portions, 0.5L hopper for 15–30g slightly larger micro doses, tool-free quick replacement to adapt full 1–30g weight range without purchasing two separate weighing devices.
Three Sets of Interchangeable 0.3L / 0.5L Mini Deep Anti-Bridging Weighing Hoppers
Each replaceable mini hopper adopts seamless full arc inner wall, cooperating with screw and vibration dual feeding to thoroughly eliminate bridging, arching and residual accumulation of hard lump spices, round ball granules, fine flour and tiny seed particles. Two cavity sizes fully cover the entire 1–30g micro weight segment, lowering raw material residual waste and cross-contamination risk during frequent switching between mixed granule, lump and powder formulas.
Optional MCU / PLC Dual Intelligent Control System With External Touch HMI
Pre-stored multi-group dedicated micro mixed-material formulas for seeds, corn, block spices, fine powder and pill granules, one-click quick recall without repeated calibration during frequent micro SKU replacement;
Real-time split three-lane micro production data display: each channel’s target tiny weight, cumulative trial bag output and residual material volume can be monitored separately on touch screen;
Independently adjustable screw rotation speed and vibration amplitude for every lane: slow screw speed + weak vibration for light fine powder to suppress dust flying, medium screw speed + mild vibration for dense granules and hard lumps to realize stable uniform feeding flow.
The whole three-lane mini weighing cavity is enclosed by semi-transparent PC dust shield, blocking mixed powder and tiny seed dust diffusion in small-batch micro-packaging workshops, while operators can rapidly locate lump/powder bridging blockage inside mini hoppers. All interchangeable hoppers, screw sleeves and vibration trays can be detached without special tools for full water washing, quickly clearing mixed heterogeneous material residue to avoid cross-contamination of different micro-dose food raw materials.
Compact Integrated Anti-Vibration Frame Adaptable For Small Micro-Batch Trial Pack Workshops
Integrated horizontal single-layer thickened compact cabinet with height-adjustable stainless steel support stand, small anti-slip load-bearing foot pads to fit narrow small-scale workshop ground. Optimized mini frame structure counteracts three-lane combined micro vibration to prevent weighing drift during uninterrupted long-hour micro-dose operation. Adapt to 0℃~40℃ temperature and 30%~95% humidity environment, internal electrical components with full dustproof and moisture-proof sealing protection, stable continuous operation in health supplement trial pack, mixed spice mini-sachet and seed sample small-batch production workshops.
Low Rated Power Consumption For Long-Hour Small-Batch Micro-Dose Continuous Production
Rated power only 1kW, much lower total energy consumption than running multiple small single-head fillers to match equivalent three-lane micro output, reducing long-term electricity operating costs for small and medium micro-trial-pack food manufacturers.
This compact three-lane screw-vibration dual-feeding single-layer 3-head linear weigher with three interchangeable 0.3L/0.5L mini anti-bridging hoppers is exclusively developed for uninterrupted small-batch synchronous packaging of mixed heterogeneous micro materials (granules, lumps, ball particles, fine powder), covering ultra-tiny trial sachets to 30g micro retail pouches within the 1g–30g weight band. It delivers stable three-lane interchangeable-cavity quantitative filling for health supplement trial pack factories, mixed spice mini-sachet production plants, organic seed sample packaging workshops and instant beverage micro trial bag filling lines.

Horizontal single-layer three independent parallel screw-vibration dual feeding & interchangeable mini micro weighing channels
Note: All listed parameters are factory standard configuration. Screw rotation speed range, vibration amplitude, mini hopper outlet width and touch screen multi-language version can be customized according to lump hardness, granule particle size, powder fineness and three-ingredient mixed micro sachet packing layout demands. 0.3L and 0.5L hopper replacement kits can be purchased separately for on-site flexible switching.
Working Principle of Single-Layer Three 0.3L/0.5L Interchangeable Mini Hopper Screw Vibration Linear Weigher
This horizontal compact single-layer 3-head linear weigher adopts three fully isolated screw-vibration dual feeding and high-sensitivity micro weighing assemblies paired with interchangeable 0.3L/0.5L mini hoppers, specially optimized for synchronous stable weighing of ultra-micro mixed heterogeneous materials (granules, lumps, ball particles, fine powder) for trial small sachets.
Raw mixed micro materials are poured into the shared top small buffer feeding hopper and evenly distributed to three independent interchangeable mini storage hoppers; each lane’s dual feeding system works synergistically: variable-speed screw pushes lumps & fine powder, low-amplitude vibration tray slides smooth granules & hard ball particles, conveying materials separately into its own mini weighing cavity without cross-channel material mixing or mutual micro-vibration signal interference. The built-in optional MCU/PLC control system independently collects real-time tiny weight data from each channel’s micro high-sensitivity load cell and executes three-lane synchronous intelligent screw & vibration adjustment logic:
Automatically slow screw rotation and reduce vibration amplitude when material weight approaches preset ultra-micro target value to guarantee unified X(0.5) high precision across all three channels;
When all three channels reach standard micro-dose target weight, three narrow-caliber bottom discharge gates open synchronously, mixed granules, lumps or fine powder slide down into downstream three-station micro trial sachet packaging equipment without residual material left inside interchangeable mini hoppers or screw/vibration feeding components.
The horizontal compact three independent interchangeable mini hopper + screw-vibration dual feeding design solves the universal feeding blockage defect of single-mode multi-head weighers for mixed lump-powder micro materials; partial small-batch production can be maintained if single lane jams, avoiding full line shutdown loss, greatly improving equipment long-hour continuous operation efficiency for micro trial sachet small-batch mixed food packaging workshops.
