1. Powder Screw Discharger
The powder screw discharger is one of the most widely used discharging devices for powder products such as flour, milk powder, coffee powder, spices, and chemical powders. It discharges material through a rotating screw inside a tube, giving continuous and accurate output. The screw speed can be adjusted to control the filling weight, making it ideal for powder filling and packaging lines. Request a quote for a powder screw discharger today.
2. Cup Dosing Device
The cup dosing device, also known as a volumetric cup filler, uses a measuring cup to discharge a fixed volume of material each cycle. It is suitable for free-flowing granules and small pieces such as rice, beans, sugar, seeds, candy, and nuts. This type of discharger is simple, cost-effective, and easy to maintain, making it a popular choice for medium-speed packaging lines.
3.Ring Discharger
The ring discharger is designed for granules and small pieces that need gentle and even discharging. Its circular structure allows material to be distributed evenly into multiple filling stations, improving packaging speed and consistency. It is often used in multi-lane packaging machines for snacks, frozen food, and small hardware items.
4. Piston Filling Machine
The piston filling machine is designed for liquid and paste products such as sauce, shampoo, detergent, honey, and cream. It uses a piston cylinder to draw and discharge a precise volume of material into each container. This discharging system offers high filling accuracy and is easy to adjust for different bottle sizes and filling volumes. Many food, cosmetic, and daily chemical manufacturers rely on piston filling machines for stable production.
5.Paste Discharging Pump
For paste, jam, cream, sauce, and other viscous products, the paste discharging pump is an essential solution. It delivers material steadily to the filling nozzle without destroying the product structure. Many food, cosmetic, and pharmaceutical manufacturers choose this pump for accurate and hygienic discharging of thick products.
6. Vibratory Bowl Feeder
The vibratory bowl feeder uses vibration to orient and discharge small components such as screws, capsules, tablets, hardware parts, and electronic components. It arranges products in a controlled direction and feeds them one by one into the packaging machine. This discharging system is widely used in hardware, pharmaceutical, and electronic packaging applications.
7. 10-Head Multihead Weigher
The 10-head multihead weigher is a high-speed and high-accuracy weighing and discharging system for granules, snacks, candy, nuts, frozen food, and hardware parts. It uses 10 weighing hoppers to combine the best weight combination for each package, minimizing giveaway and improving efficiency. If you need a reliable, high-capacity discharging solution for your packaging line, the 10-head multihead weigher is often the first choice.
8. 14-Head Multihead Weigher
The 14-head multihead weigher offers even higher speed and accuracy than the 10-head model. With 14 weighing hoppers, it can handle more complex weighing requirements and achieve faster packaging speeds. It is ideal for large-scale production lines that require maximum efficiency and minimum product giveaway. Many customers choose this model when they need to increase output without sacrificing accuracy.
9. 4-Head Linear Weigher
The 4-head linear weigher is a compact and cost-effective weighing and discharging system for granules, rice, sugar, seeds, and small pieces. It uses 4 linear weighing hoppers to discharge material with good accuracy at a moderate speed. This model is perfect for small to medium production lines where space and budget are important considerations.
How to Choose the Right Discharging System?
To select the best discharging system for your packaging machine, consider the following factors:
- Material characteristics: powder, granule, liquid, paste, or solid piece
- Filling accuracy requirement: how many grams or milliliters per package
- Production speed: how many packages per minute
- Product structure: whether the material must be handled gently
- Integration with existing packaging machines
| Material Type | Recommended Discharging System |
|---|---|
| Powder | Powder Screw Discharger, Cup Dosing Device |
| Granules | Cup Dosing Device, 10-Head Multihead Weigher, 14-Head Multihead Weigher, 4-Head Linear Weigher, Ring Discharger |
| Liquid | Piston Filling Machine |
| Paste / Viscous | Piston Filling Machine, Paste Discharging Pump |
| Small Components | Vibratory Bowl Feeder, Ring Discharger |
Quick notes:
- Powder – Powder Screw Discharger is the most common choice for accurate powder filling.
