Dried Fruits & Nuts Packing Line with 14 Head Multihead Weigher
Application
In the dried fruits and nuts industry, packaging is not just about sealing products — it directly impacts shelf life, product appearance, and production efficiency.
For products like prunes, raisins, nuts, and seeds, challenges such as stickiness, irregular shapes, and dust require a highly optimized packaging solution.
This article introduces a full automatic packaging line designed for dried fruits and nuts, equipped with a 14 head multihead weigher with dimple plates, capable of handling both standard and sticky materials with high accuracy and stability.

A complete packaging line typically includes:
1. Feeding System
Inclined elevator (skirt type)
Easy-clean design for food safety
Prevents small products from falling
2. Weighing System
14 head multihead weigher
2.5L hopper with dimple plates
High-speed and high-accuracy weighing
Especially suitable for:
Sticky products (prunes, dried mango)
Small granules (seeds, nuts)
3. Packaging Machine (VFFS)
Vertical Form Fill Seal (VFFS) machine
Supports:
Pillow bags
Gusset bags (side sealing)
Square forming tube for stable gusset shaping
Double servo system for high-speed performance
4. Auxiliary Systems
Nitrogen flushing system (extend shelf life)
TTO printer (date/batch coding)
Punch hole device (Euro hole)
Easy tear notch
Finished product conveyor
Rotary accumulation table
Why Dimple Multihead Weigher is Essential for Sticky Products
Sticky products like prunes are one of the most difficult materials to handle.
Common problems:
Product sticking inside hopper
Inconsistent discharge
Weight accuracy fluctuation
Solution: Dimple Surface Design
The dimple plates reduce contact surface and friction, ensuring:
Smooth material flow
Stable weighing performance
Reduced material residue
👉 This is a must-have configuration for sticky dried fruits.
This packaging line supports multiple bag styles:
✔ Pillow Bag (Back Seal)
Most common and cost-effective
Suitable for small to medium sizes
✔ Gusset Bag (Side Sealing)
Better shelf display
Higher-end appearance
Can stand more easily
Production Speed & Capacity
The actual speed depends on product type, weight, and bag style.
Typical Output:
| Weight | Bag Type | Speed |
|---|---|---|
| 35g | Pillow | up to 40 bags/min |
| 90g | Pillow | 30 bags/min |
| 200g | Pillow (prunes) | 25–30 bags/min |
| 500g | Pillow | 15–20 bags/min |
| 200g | Gusset | 25–30 bags/min |
| 400g | Gusset (double dump) | 15–20 bags/min |
| 500g | Gusset | 15–20 bags/min |
What is “Double Dump” and When Do You Need It?
For larger weights like 400g or above, a single weighing cycle may not be sufficient.
Double Dump System:
Two weighing cycles per bag
Ensures higher accuracy
Slightly reduces speed
👉 Ideal for:
Large weight packaging
High accuracy requirements
Key Technical Features
✔ Double Servo System
One servo for film pulling
One servo for sealing
Ensures stable high-speed operation
✔ Independent Temperature Controller
More stable than touchscreen-only control
Better sealing consistency
Suitable for laminated films
✔ Nitrogen Flushing System
Reduces oxidation
Extends shelf life
Essential for nuts and dried fruits
