Long Biscuit Weighing & Cartoning Packaging Line

This automatic packaging line is engineered exclusively for long, fragile, stick-shaped food prone to bridging and jamming during packaging. The whole line is modularly assembled with elevator, special multihead weigher for long strips, vibration sorting unit, box dispenser, box conveyor and packaging machine.

It completes full automatic workflow: automatic lifting feeding, combination weighing, vibration sorting, box dispensing, box conveying, vertical cartoning and final packaging. The line solves common industry pain points of long stick products including material jamming, bridging, messy arrangement, weighing deviation and irregular cartoning. Built with food-grade construction, compact modular layout and low failure rate, it replaces manual counting, weighing and cartoning, cutting labor cost and product breakage rate. It is the ideal automated packaging solution for standardized mass production in snack food factories.

Suitable Materials

This packaging line handles regular and semi-regular long stick food products, including long biscuits, finger biscuits, soda biscuit strips, wafer sticks, chocolate sticks, rice bar snacks and energy bars.

It works best for long strips that easily bridge, stack and jam, fragile snacks requiring minimal drop impact, products needing neat vertical feeding, and snack items requiring automatic weighing and quantitative cartoning. Final performance will be evaluated based on material dimension, brittleness, surface coating, box type and required production capacity.

Industry Pain Points & Solutions

• Pain Point 1: Inaccurate weighing due to stacked or tilted long materials Solution: Custom multihead weigher for long strips prevents stacking and side tilting, delivering stable and consistent weighing results.

• Pain Point 2: Material bridging, stacking and feeding blockages Solution: Independent collecting + vibration sorting design breaks material accumulation and eliminates jamming.

• Pain Point 3: Skewed and messy products inside finished cartons Solution: Vertical feeding and orderly sorting enable neat, uniform cartoning and better visual quality.

• Pain Point 4: High labor cost and low manual throughput Solution: Fully automatic workflow removes manual weighing, arranging and cartoning work to save labor and reduce human error.

• Pain Point 5: High breakage and chipping rate for fragile stick snacks Solution: Gentle flexible conveying avoids collision and extrusion to lower product waste.

• Pain Point 6: Low production capacity from manual packaging Solution: Continuous high-speed automatic operation supports large-batch order production.

Core Product Features

1. Special Multihead Weigher for Long Strips, Stable Precise Weighing

Equipped with customized combination weigher dedicated for long materials. The rotary feeding disc feeds V-shaped vibrating tray evenly to spread long strips flat and prevent stacking or overturning. Conical hoppers and special weighing buckets match the shape of stick food, supporting vertical discharging with even force. It improves weighing accuracy and fixes the common weighing error issue for long products.

2. Dual Design of Independent Collection + Vibration Sorting for Anti-jamming

The integrated vibration sorter collects materials first, then arranges products via high-frequency stable vibration. It breaks stacked material piles and eliminates bridging, ensuring smooth feeding and consistent vertical orientation before cartoning.

3. Optimized for Long Stick Materials, Stable Operation & Low Breakage

The whole line is optimized for mechanical characteristics of fragile long snacks. Vertical gentle conveying without hard squeezing or pulling protects biscuit integrity and reduces chipping and breakage. The closed-loop automatic system runs continuously with low failure rate for heavy-duty factory operation.

4. Modular Integrated Structure, Simple Operation & Maintenance

Composed of independent modules: elevator, multihead weigher, sorting unit, box dispenser, conveyor and packaging machine. Compact footprint simplifies workshop layout. Adjustable parameters support quick switch between different product specifications. Modular assembly makes inspection, maintenance and spare part replacement simple and reduces running costs.

5. Fully Automatic Closed-Loop Production to Boost Profit

Full automatic operation from feeding, weighing, sorting, box dispensing, conveying to finished packaging. It minimizes labor input and human weighing mistakes, lifting cartoning pass rate and product appearance consistency for standardized smart manufacturing.
