Volumetric Cup Packing Machine
Volumetric Cup Packing Machine Typical Applications
- Food Grains & Seeds: rice, beans, lentils, corn, wheat, seeds.
- Seasonings & Condiments: sugar, salt, spice blends.
- Snacks & Nuts: peanuts, cashews, pistachios, sunflower seeds.
- Pet Food: dry kibbles, fish feed.
- Non-Food Granules: detergent granules, fertilizer pellets, plastic resins.
A Volumetric Cup Packing Machine is a type of Vertical Form Fill Seal (VFFS) system that uses rotating measuring cups to dispense products by volume rather than by weight. It is one of the simplest and most widely used solutions for granular and free-flowing materials.
🔹 How it works step by step:
- Film unwinding & bag forming – A roll of packaging film is unwound and shaped into a tube by the forming collar.
- Volumetric cup dosing – The product flows from a hopper into a set of adjustable cups mounted on a rotating disc. Each cup holds a fixed volume of product.
- Product drop – When the cup rotates to the filling position, it releases its contents into the formed bag tube.
- Sealing & cutting – The vertical and horizontal sealing jaws close the bag and cut it, creating a finished package.
- This process repeats continuously, allowing the machine to produce dozens of packs per minute with minimal manual intervention.
🔹 Why use volumetric cups?
- Cost-effective: A volumetric cup system is much cheaper than advanced weighing systems (like multi-head weighers).
- Simplicity: Fewer moving parts → easier to operate, clean, and maintain.
- Speed & efficiency: Suitable for high-speed operations where extreme precision isn’t required.
- Consistency: Ensures each bag has a uniform fill volume.
🔹 Advantages compared to other systems:
- vs. Multi-head Weigher: Lower cost, simpler design, but less precise. Multi-head weighers are preferred for high-value snacks where accuracy matters more.
- vs. Auger Filler: Cup filler is better for free-flowing granules, while auger is for powders (flour, milk powder, spices).
- vs. Liquid Pump: Cup filler is only for dry granules, not liquids or pastes.
🔹 Limitations to be aware of:
- Accuracy depends on product density; if the density changes (e.g. moisture in rice), the actual weight per cup may vary.
- Not suitable for sticky, irregular, or non-free-flowing products.
- For premium products where weight accuracy must be exact, a multi-head weigher is a better choice.
👉 In summary: The Volumetric Cup Packing Machine is the most affordable, simple, and efficient choice for packaging free-flowing granules. It is perfect for manufacturers who need fast ROI, stable performance, and consistent bag filling without the high cost of weighing systems.

FAQ About Volumetric Cup Packing Machine
Q1: What type of products can be packed with a volumetric cup machine?
A1: This machine is ideal for free-flowing granular products such as rice, beans, sugar, salt, seeds, nuts, and pet food. It can also handle non-food granules like detergent, fertilizer, or plastic pellets.
Q2: How accurate is the volumetric cup filling compared to weighing machines?
A2: For stable-density products, accuracy is usually within ±1–2%. If exact weight accuracy is critical (e.g. for high-value snacks or products sold strictly by weight), a multi-head weigher may be more suitable.
Q3: What bag types can the machine produce?
A3: Depending on the host VFFS system, it can produce pillow bags, gusset bags, and back-seal bags. Bag sizes are adjustable via forming sets.
Q4: What is the typical speed of the machine?
A4: Typical speeds range from 30–120 bags/min, but the actual performance depends on the product, film material, and chosen host machine configuration.
Q5: How difficult is it to operate and maintain?
A5: Very easy. The volumetric cup system has a simple structure with fewer moving parts, making it easier to clean, adjust, and maintain compared to complex weighing systems.
Q6: Can the machine be upgraded later to other dosing systems?
A6: Yes. One advantage of Soontrue’s modular design is that manufacturers can start with a volumetric cup filler and later upgrade to multi-head weighers, auger fillers, or liquid pumps as their business grows.
Q7: What industries benefit most from this machine?
A7: Food grains, snacks, seasoning, and pet food industries use it extensively. Non-food industries like chemicals, fertilizer, and detergents also benefit where volume dosing is sufficient.
Q8: What after-sales support does Soontrue provide?
A8: Soontrue offers installation, operator training, spare parts supply, and 24/7 remote service through a global network. This ensures smooth machine startup and long-term stable performance.
