Automatic Dried Orange Slice Weighing & Packaging Line | 10 Head Multihead Weigher VFFS Production Line

This fully automated packaging line is custom-built for light, fluffy, sticky and brittle dried orange slices, including sugar-candied orange slices, low-temperature dehydrated orange slices and freeze-dried citrus slices.

The whole system consists of three core units: large-angle inclined belt elevator, 10-head combination multihead weigher and vertical form fill seal (VFFS) packaging machine. It realizes fully unmanned workflow from feeding, precise weighing, bag forming, heat sealing to finished product output.

Dried orange slices feature low unit weight, bulky volume, sticky sugar coating and fragile texture. Ordinary volumetric cup feeders or single-head weighing machines frequently result in inaccurate weighing, material bridging, high breakage rate and poor sealing performance. Our production line takes the 10-head multihead weigher as the core, calculating the optimal weight combination from multiple weighing hoppers. Paired with gentle feeding from the inclined elevator and stable bag forming of the vertical packer, we keep weighing tolerance, bag appearance and slice breakage rate within ideal ranges. It is the ideal automated production line for dried fruit, preserved fruit and fruit crisp manufacturers to boost output and packaging consistency.

Compatible Materials

     Core Target Materials

• Other light & flaky sticky materials: oatmeal crisps, puffed snacks, seaweed sheets, biscuits

Pain Points We Solve

1. High labor cost & unstable weighing error Manual weighing is slow with inconsistent gram weight. Overfilling causes raw material waste while underweight triggers customer complaints. Labor expenditure keeps rising year by year.

2. Uneven flaky slices lead to material bridging & jamming Thin, irregular orange slices with slight sugar adhesion easily stack and block single-hopper feeding, leading to unstable weighing results.

3. High breakage rate caused by violent material transfer Brittle orange slices break easily when falling from high drop heights or bumping during transportation, ruining finished product appearance and commercial value.

4. Poor sealing causes moisture absorption & short shelf life High sugar content makes dried orange slices highly hygroscopic. Loose sealing leads to softening, flavor loss and shortened shelf life.

5. Discrete standalone machines lead to messy production Separate feeding, weighing and packing equipment requires multiple workers to transfer materials; production synchronization is poor and workshop layout is chaotic.

Core Machine Features

1. Large-Angle Inclined Elevator — Gentle Feeding, Zero Damage

Compact footprint with high lifting height; directly convey materials from ground to the weigher hopper without intermediate transfer. The skirt baffle belt ensures slow, smooth material running, greatly reducing orange slice breakage.

2. 10-Head Combination Multihead Weigher — Gram-level Precision & Fast Speed

Ten independent weighing hoppers run parallel calculation. The system automatically selects the best weight combination to hit the target weight accurately.

High-precision load cells plus digital filtering algorithm resist workshop vibration and guarantee stable weighing readings even for tiny lightweight orange slices

3. Vertical VFFS Packaging Machine — Neat Pouches & Airtight Seals

Servo film pulling system with photoelectric color mark tracking, ensuring accurate pattern position and clean, straight cutting without skew. Dual-layer heat sealing creates tight airtight seams to prevent moisture ingress.

4. Whole-Line PLC Synchronization — One Operator Runs the Entire Line

Unified PLC control links elevator, multihead weigher and vertical packer automatically. The elevator stops feeding when the weigher hopper is full and restarts automatically when material runs low, avoiding idle running and energy waste.

5. Tool-Free Quick Disassembly, Easy Sanitary Cleaning

All food-contact parts including weighing hoppers, vibrating feeders and chutes can be disassembled without tools, convenient for water washing, sanitization and cross-product switching, fully meeting food factory hygiene standards.

Working Process

1. Raw Material Feeding: Pour dried orange slices into the elevator bottom hopper; can also connect upstream vibrating sieve or drying room turnover carts.

2. Inclined Conveying: Materials run slowly upward along the skirt baffle belt and smoothly drop into the central storage hopper of the multihead weigher.

3. Material Distribution: The storage hopper feeds material evenly into 10 weighing hoppers to maintain balanced material volume across all hoppers.

4. Combination Calculation & Discharging: The control system picks out the hopper combination closest to the target weight, then opens hoppers synchronously to drop materials into the collecting chute.

5. Bag Forming: Roll film passes through the forming collar and is sealed longitudinally into a tube-shaped pouch.

6. Material Filling: Orange slices slide down the optimized-angle discharge pipe with low drop height to avoid impact and breakage.

7. Sealing & Cutting: Horizontal sealing jaws finish top & bottom sealing and cut the pouch automatically.

8. Finished Product Output: Conveyor sends out finished pouches; can be extended with date coding, metal detection, weight sorting and carton sealing stations.

Configuration & Selection Guide

1. 30–100g Retail Small Pouches 10-head multihead weigher + medium-width vertical packer + back-seal pillow bags; production speed: 40–60 bags per minute.

2. 150–500g Family-Size Pouches Upgrade to larger hoppers and wider discharge chutes; optional gusseted stand-up pouches for a stiff three-dimensional shape.

3. Export & Long Shelf-Life Products Must add nitrogen flushing system + aluminum foil / metallized film; match with weight checker and metal detector to remove defective products.

4. High-Moisture Sugar-Coated Orange Slices Choose mirror-polished stainless steel hoppers with larger opening angles; provide spare disassembleable hoppers for backup.

5. Workshop Height Restriction Reduce elevator inclination angle or replace with Z-type bucket elevator; we provide on-site survey and free production line layout drawings.
