In automated packaging production for food, pharmaceutical and chemical industries, quantitative weighing is always a critical node that impacts overall production line efficiency and finished product quality. Many manufacturers face common pain points when upgrading their production lines:
Large weighing errors and high material waste from conventional weighing equipment
Poor versatility for materials of different forms (fine powder & small granules); full set equipment replacement is required for product change overs
Equipment operating speed fails to match packaging machine capacity, resulting in production line idle waiting
Difficulty meeting custom requirements; long lead times from resellers and slow after sales support
As an original manufacturer of linear weighers,LEESOLU has independently developed a comprehensive lineup of single head, double head, four head, six head and eight head linear weighers.Leveraging multi sensor combined weighing technology together with MCU / PLC control systems, we deliver reliable hardware solutions for automatic quantitative weighing of granular and powdery materials.
1. Core Product Specifications to Cover Diverse Weighing Ranges
Equipped with independent weighing load cells, LEESOLU linear weighers apply intelligent algorithms to calculate optimal weight combinations, balancing high weighing accuracy and production throughput. Different models cater to varied materials and capacity requirements.

3 Head Screw Vibration Feeding Linear Weigher
Weighing range: 1-30 g | Optional hopper: 0.3 L / 0.5 L | Max speed: 30 packs/min | MCU / PLC dual control options Designed for low weight granules and spherical materials.
2. Cross Industry Real World Production Applications
LEESOLU linear weighers are not industry specific and have been widely deployed across food, pharmaceutical and chemical sectors.
Food Industry: Weighing for rice, white sugar, sesame, nuts, sunflower seeds, puffed snacks, black sesame, mixed congee raw materials and other grain & leisure food ingredients.
Pharmaceutical Industry: Dosing for herbal slices, pharmaceutical pellets and pills.
Chemical Industry: Weighing for plastic pellets, polymer particles, washing powder and other chemical granules & powders.
Our weighers can operate as standalone units or be integrated into full automatic packaging systems. Typical projects include mixed nut weighing & packaging lines and combined powder granule packaging workflows. The equipment can link with material feeders and packaging machines to realize fully automated processes: raw material feeding → quantitative weighing → final filling.
Vibration trays and hopper structures can be customized to handle granules, general powders and slightly sticky materials according to unique material properties.
3. Technical & Delivery Advantages as Original Equipment Manufacturer
As an in house manufacturer, LEESOLU completes core hardware development and mechanical design internally. Compared with trading resellers, we offer obvious strengths in equipment customization, delivery and mechanical modification.
✅ Customized Model Selection
We recommend suitable configurations based on your material characteristics (powder / granule), target weighing weight, required line speed and material stickiness. Solutions cover weighing from 1 g up to 5000 g.
✅ Modular Stainless Steel Construction
Main bodies are built in stainless steel. Material contact components can be manufactured to food grade or pharmaceutical grade hygiene standards for easy cleaning and reduced material residue.
✅ System Integration Compatibility
Output signals support connection with vertical form fill seal machines and premade pouch packing machines, enabling retrofitting and full line automation upgrades.
✅ Pre sale Material Testing Service
Customers may send sample materials for weighing trials. We verify weighing precision and discharging performance with your actual goods to lower procurement risks.
4. Frequently Asked Questions about Linear Weigher Selection
Q1: How to solve powder bridging and poor material flow?
A: For poorly flowing powders such as flour, select screw feed linear weighers. The forced screw feeding eliminates arching and intermittent discharging. Vibration discharge structures are recommended for common granular materials.
Q2: Linear weigher vs multi head combination weigher — which one should I pick?
A: Linear weighers are preferred for powder based materials. Multi head combination weighers fit small granules and multi ingredient mixes like mixed nuts. LEESOLU will suggest the optimal solution based on your material traits.
Q3: What does after sales service include?
A: As original manufacturer, we supply installation guidance and operator training. Original spare parts are supplied directly from our factory. We also provide mechanical and program adjustment support for future production line upgrades.
Conclusion
Quantitative weighing is the core module of every automated packaging line. When selecting weighing equipment, do not focus merely on unit price. Material properties, weighing range and production line speed should be prioritized.
Automated mesh bagging extends produce shelf life by providing vital airflow. Upgrading your line slashes labor costs, stops product giveaway, and maximizes daily output.
Dust-controlled powder fillers use vacuum extraction and servo-driven augers to package fine materials. These automated systems prevent waste, ensure safety, and maximize ROI.
Horizontal packaging machines use lateral movement to safely package solids, powders, and liquids. These systems ensure leak-proof seals, cut labor costs, and maximize your ROI.
