Introduction
In the food processing and packaging industry, handling sticky products such as marinated meats, cooked pasta, candies, or fresh salads has always been a major challenge. Stickiness often leads to clogged equipment, inaccurate weighing, and difficult cleaning—problems that seriously reduce efficiency and compromise product quality.
Traditional vibratory multihead weighers struggle with these materials. Thankfully, innovation has introduced a better alternative: the Multihead Weigher with Screw Feeder. Designed specifically for sticky, wet, or oily products, this system offers a breakthrough solution to one of the industry’s toughest challenges.
This article compares standard multihead weighers with screw feeder multihead weighers, helping you make the right choice for your production line.
Challenges of Standard Multihead Weighers with Sticky Products
Traditional multihead weighers rely on vibration to move product through the system. While this works well for free-flowing, dry products like chips, nuts, or cereals, sticky products reveal the system’s limitations:
- Product Adhesion & Blockages: Sticky foods often cling to vibrating trays and weighing hoppers, slowing down product flow or causing complete blockages that force frequent stoppages.
- Reduced Accuracy: Product buildup interferes with sensors, resulting in inaccurate weights that lead to costly overfills or underweight packages.
- Hygiene & Cleaning Issues: Sticky residues are challenging to remove, requiring extended cleaning times and raising concerns about food safety.
The Screw Feeder: A Revolutionary Solution for Sticky Products
To overcome these challenges, engineers developed the multihead weigher with screw feeder. Instead of vibration, this system uses rotating screw rods to push sticky products forward gently.
The result? Smooth product flow, minimal adhesion, and highly accurate weighing.
As industry experts highlight, the screw feeder design fundamentally solves the sticky product problem by forcing steady movement of material directly into the weighing hoppers, eliminating buildup and downtime.
Core Advantages of Screw Feeder Multihead Weighers
| Advantage | Description |
|---|---|
| Prevents Blockages | The rotating screw continuously pushes product forward, ensuring smooth flow without adhesion. |
| High Weighing Accuracy | With no product sticking to weigh buckets, sensors deliver precise readings with minimal error. |
| Easy to Clean | Many models meet IP69K hygiene standards, allowing high-pressure, high-temperature washdowns. |
| Versatile Applications | Ideal for sticky, moist, or oily products like marinated meats, seafood, salads, or cheese shreds. |
Comparison: Multihead Weigher vs. Screw Feeder Multihead Weigher
| Feature | Standard Multihead Weigher (Vibratory) | Screw Feeder Multihead Weigher |
|---|---|---|
| Feeding Method | Vibration | Rotating screw |
| Best For | Dry, free-flowing particles | Sticky, moist, oily products |
| Risk of Blockages | High | Very low |
| Weighing Accuracy | Reduced due to the buildup | Extremely high |
| Cleaning Difficulty | High, sticky residues remain | Low, supports washdown |
| Production Efficiency | Lower due to stoppages | High, smooth continuous flow |
How to Make the Right Choice
The decision depends on your product type and production needs:
-
Choose Standard Multihead Weighers if you handle dry, free-flowing products like chips, nuts, or cereals. They are cost-effective and reliable for non-sticky applications.
-
Choose Screw Feeder Multihead Weighers if you process sticky, oily, or wet products like marinated chicken chunks, fresh salads, or shredded cheese. Though the upfront investment may be higher, the gains in stability, hygiene, and accuracy quickly repay the cost through efficiency and reduced downtime.
Conclusion
Selecting the right weighing equipment is critical to ensuring efficiency, accuracy, and food safety on your packaging line. While standard multihead weighers work well for dry goods, they fall short with sticky materials. The multihead weigher with screw feeder stands out as the ultimate solution, offering smooth product handling, unmatched weighing precision, and easy cleaning.
By investing in the right technology for sticky product packaging, you can eliminate production headaches, boost efficiency, and gain a significant competitive edge.
