Benefits of Volumetric Cup Filler VS Auger Filler l Vtops Blog

Table of Contents

Most of the time, the type of products being packaged dictates the choice of auger filler or volumetric cup filler. However, sometimes the experience of the manufacturer, and sometimes the preference of the end user will select the filler machine. VTOPS summarizes the benefits of volumetric cup filler VS auger filler based on our own experience; please refer to the list below:

What Are the Differences, Advantages, And Disadvantages of Cup Filler VS Auger Filler

1. Principle of Operation

  • Auger Filler: An auger filler uses a screw-like tool to transport and dispense dry products, such as powders and granules. The auger is rotated by a motor, which pulls the product through a hopper and into a funnel-like tube, where it is dispensed into the packaging.
  • Volumetric Cup Filler: A volumetric cup filler uses pre-measured cups that are filled with a specific volume of product. The cups are then emptied into the packaging.

2. Versatility

  • Auger Filler: Auger fillers can be used to fill a wide range of free-follow, non-free-flow, dusty products, including dry powdery and even small granular products.
  • Volumetric Cup Filler: Volumetric cup fillers are best suited for filling free-flowing dry granular products without dust, such as coffee beans, fine sugar, and uniform particle snacks.

3. Accuracy

  • Auger Filler: Auger fillers are very accurate and can dispense products within a few grams deviation of the target weight.  And the auger fillers have 2 filling methods it is fill-by-volume and fill-by-weight. The accuracy of fill-by-volume is more than 99%, but the accuracy of fill-by-weight is even higher up to 99.7%.
  • Volumetric Cup Filler: Volumetric cup fillers are less accurate than auger fillers and can have a variance of up to 1% of the target weight depending on the target weight and product particle size and weight.

4. Speed

The speed of speed is a relative concept, which depends on many factors, such as the characteristics of the filling product, the diameter of the feed port of the received bottle, filling weight, etc.

  • Auger Filler: Auger fillers can fill products at a relatively high speed about 10 to 35 fill per minute, but the speed may vary depending on the product being filled and the driven motor.
  • Volumetric Cup Filler: Volumetric cup fillers are generally faster than auger fillers, and the speed is relatively stable at 30-45 beats per minute, but they can still fill products at a more higher theoretical speed.

5. Cost

  • Auger Filler: Auger fillers are typically more expensive than volumetric cup fillers due to their greater complexity and accuracy.
    However judging from the sales data of buying powder filling machines on the Alibaba platform, the sales price of semi-automatic screw filling machines is within a reasonable range of 2,000-5,000 US dollars, and the fully automatic auger filler models have different integrated functions and are not of reference significance.
  • Volumetric Cup Filler: Volumetric cup fillers are more affordable than auger fillers, making them a popular choice for small to medium-sized businesses.

6. Maintenance

  • Auger Filler: Auger fillers require regular maintenance to ensure the screw remains clean and lubricated. They may also require periodic replacement of the auger and other parts.
  • Volumetric Cup Filler: Volumetric cup fillers require less maintenance than auger fillers since they have fewer moving parts.

Summary

Cup fillers are often overlooked in favor of auger fillers. From VTOPS experience, coffee beans, rice, kidney beans, fine sugar, sprinkles, etc., are dust-free, free-flowing, and have uniform particles and a consistent shape that are ideal for filling with cup fillers. Because for these products, the cup filling has a good speed. Of course, some of these products are great for auger fillers.

In summary, the main advantages of auger fillers are their accuracy and versatility, while the main advantages of volumetric cup fillers are their affordability and ease of maintenance. The choice between the two will depend on the specific product being filled, the required accuracy, and the budget of the business.
