When it comes to packaging sticky, wet, or difficult-to-flow products, a standard ميزان متعدد الرؤوس often falls short. That’s where the وحدة وزن متعددة الرؤوس مزودة بمغذي لولبي comes in—a specialized family of موازين مركبة designed to handle the most challenging materials in food packaging and beyond.
In this comprehensive guide, we’ll explore the various types of screw feeder الميزان, their unique features, and how to choose the right configuration for your product.
What Makes a Screw Feeder Multihead Weigher Different?
أ وحدة وزن متعددة الرؤوس مزودة بمغذي لولبي (يُعرف أيضًا باسم وحدة وزن مركبة مزودة بمغذي لولبي) is not a single machine—it’s a diverse family of weighing solutions. Each configuration is engineered to address specific product challenges, from sticky sauces and marinated meats to delicate vegetables and fragile snacks.
The key difference lies in how these موازين متعددة الرؤوس transport product through the system. Instead of relying solely on vibration, they incorporate screw conveyors that actively move sticky or clumping materials, ensuring consistent flow and accurate weighing.

Classification 1: Surface Treatment Options
The contact surface of your ميزان مركب has a significant impact on product flow. Here are the main options:
Flat Stainless Steel Surface
الأفضل لـ: Free-flowing or moderately sticky products
- Standard 304 stainless steel
- Smooth, easy-to-clean surface
- Cost-effective option
- Suitable for products like dry snacks, nuts, or lightly coated items
Dimpled (Embossed) Stainless Steel Surface
الأفضل لـ: Sticky or wet products
- Reduces contact area between product and surface
- Minimizes friction and sticking
- Created through embossing process with specialized dies
- Pattern varies by manufacturer (small dimple, honeycomb dimple, etc.)
- Ideal for marinated meats, cheese, wet vegetables
Teflon-Coated Surface
الأفضل لـ: Extremely sticky or adhesive products
- Applied to either flat or dimpled stainless steel
- Maximum non-stick performance
- Essential for products like sauces, sticky candies, or heavily marinated items
- Requires periodic re-coating depending on usage
نصيحة احترافية: Many modern ميزان متعدد systems combine dimpled surfaces with Teflon coating for ultimate anti-stick performance.
Tip 💡： Modern multihead weighing systems often combine dimpled surfaces with Teflon coating for ultimate anti-stick performance.
Classification 2: Screw Feeder Pan Configurations
The orientation and design of screw feeders in your ميزان متعدد الرؤوس determine how effectively it handles your specific product.
Horizontal Screw Feeder Pans
The most common configuration for screw feeder موازين مركبة.
Vertical (Upright) Screw Feeder Pans
الأفضل لـ: Short, wet, oil-coated products
- التطبيقات: Radish cubes, pickled vegetable stems, wet pasta
- المزايا: Excellent drainage, prevents product clumping
- How it works: Vertical screws lift product upward before dropping into weigh buckets
- Unique benefit: Gravity assists in separating sticky pieces
Single Screw
- الأفضل لـ: Larger pieces with moderate stickiness
- التطبيقات: Diced meat, chicken chunks, vegetable pieces
- المزايا: Gentle product handling, less product damage
- سرعة: Moderate to fast
Double Screw
- الأفضل لـ: Highly sticky or fibrous products
- التطبيقات: Marinated radish strips, squid strips, spicy fish, sauced noodles
- المزايا: Anti-tangling design, prevents product bridging
- سرعة: Moderate (prioritizes accuracy over speed)
Key Difference: The main vibration pan and linear feeder pans in vertical screw الميزان are oriented differently than horizontal models, creating a distinct product flow pattern.
Classification 3: Hopper Opening Systems
How your جهاز وزن متعدد الرؤوس releases product is critical for accuracy and cleanliness.
Standard Double-Door Hoppers
- Design: Two pneumatic doors open simultaneously
- الأفضل لـ: المنتجات ذات التدفق الحر
- Limitation: May leave residue with sticky products
Scraper-Style Double-Door Hoppers
- Design: Doors with integrated scraper blades
- الأفضل لـ: Sticky, adhesive, or wet products
- المزايا: Ensures complete product discharge, Prevents residue buildup, Maintains weighing accuracy, Improves hygiene, and reduces waste
لماذا هذا مهم: Even small amounts of residue can affect the next weigh cycle’s accuracy
Industry Standard: Most screw feeder موازين مركبة now use scraper-style hoppers as the default configuration.
Classification 4: Discharge Chute Designs
The discharge chute is where your ميزان hands off product to the packaging machine—and it’s often the largest contact surface with sticky materials.
خيارات السطح
- Dimpled stainless steel – Good for moderately sticky products
- Dimpled + Teflon coating – Better for very sticky products
- Flat stainless steel + Teflon coating – Best for liquid-like products
Structural Configurations
Multi-Panel Chute (3-4 Panels) Design: 3-4 stainless steel panels form a single large chute
المزايا:
- Universal fit for various products
- تكلفة أقل
- Easier to manufacture
Disadvantages:
- Larger internal volume may cause the product to swirl or tumble
- Less precise product placement
- Potential for product damage
Individual Chute System
- Design: Each row of weigh buckets has its own dedicated chute
- المزايا: Product slides down like individual slides, Minimal product interaction ,Precise placement into bags or containers, Reduced product damage, Better for delicate items
- الأفضل لـ: Premium products, delicate items, or when precise bag placement is critical
- Trend: Individual chute systems are becoming the preferred choice for high-value products and applications requiring maximum accuracy.
Choosing the Right Screw Feeder Multihead Weigher Configuration
