Some Problems You Will Meet When Picking an Auger Filler

Flour, milk powder, food additives, etc., are common dry powdered food in our lives. As people’s awareness of consuming safety continues increasing our daily bread, the requirements for powdered food packaging, quality, and safety are increasing. Dry powder products have special packaging equipment requirements due to their characteristics of dispersible and dust during filling. Currently, the dry powder filling machine on the market mainly adopts the auger metering method.

When you choose a suitable auger filler with many factors. Zhengzhou Vtops Machinery Co Ltd is a reliable Auger Filler Supplier from China, and we offer different high-quality auger filler machines. VTOPS summarizes the following factors to help you make the right choice.

Basic Structure

The primary dry powder filling machine comprises an auger filler and an optional screw conveyor feeder. The outlet of the screw conveyor feeder is connected to the top of the hopper of the auger filler by a soft connection. The dry powders in the hopper of the screw conveyor feeder will be conveyed to the hopper of the auger filler by screw feeder blades.

Double blender blades mounted inside the hopper of auger filler and arranged at 180 degrees. The blender-blades are in constant rotation when loading and filling. To ensure dry powders uniformed distribution in the hopper of auger filler which powders delivered from the hopper of screw conveyor feeder. And the dry powders uniformly enter the auger under the influences of gravity and blades, thereby ensuring the filling precision and continuity of the dry powders.

Closed Design

In addition, we know that most of the dry powders are microcrystalline powders with smaller particle size. When conveying and filling in the packaging process, they are easy to leak out through the form of dust, which causes waste of finished materials and it is also not good for workers’ health. Therefore, the filling of dry powder requires a relatively closed space to ensure that the dry powder does not leak. A dust removal device can be added if necessary.

Ways of Filling

Fill By Volume

For everyday applications, every food packaging all has a net content weight. The constant filled weight is the result of our often-called quantitative filling. According to the feedback from market researchers of Vtops Machinery “At present, many auger fillers do not have a quantitative filling device, even if they have a quantitative device, the device need to be set separately. Such as, mostly filled weight need to subtracting the weight of the bags or bottles. This will affect the filling efficiency and the accuracy is not accurate enough. Affect the user’s experience.”

Fill By Weight

Of course, while the auger fillers realized quantitative filling of the materials, the accuracy, speed and efficiency of the filling can not be ignored. For customers with high precision requirements, they often care about error as low as 0.1%. So, the high precision research and development has always been the unremitting pursuit of professional manufacturers.
As a professional R&D manufacturer of auger fillers, Vtops Machinery newly designed and developed a high-precision double-head auger filler which has the function of online weighing system, and the filling error is within 1 gram for 1kg. At present, the high-precision double-head auger filler has been exported to German and Australian milk powder manufacturers and received excellent feedback.

Fill By Vibrating

Some powders are relatively bulky have a low density. Vibration occurs during transportation will cause the powders to become tight, which increases the density of the dry powders and increases the space in the container. After the customer purchases the product, the customer will have a bad shopping experience when saw the half of the containers are empty. Therefore, for such low-density bulky packing manufacturers, an auger filler with Filling-by-Vibrating characteristic will be necessary.

Hopper

Different hoppers have different functions. So far, VTOPS company have three types of hoppers: Primary Hopper, Monitorable Hopper, and Split Hopper.

Primary Hopper

The primary hopper is a powder storage container made of a complete stainless steel coil. This hopper has been eliminated by us.

Advantage: Lower cost.

Disadvantage: Can’t see the state inside the hopper, poor quality.

Monitorable Hopper

The monitorable hopper is made of transparent plexiglass and 304 food-grade stainless steel to form the inverted cone hopper. All auger filler machines of VTOPS are currently equipped with the monitorable hopper or an upgraded version of this hopper.

Advantage: The clear plexiglass allows the operator to easily and clearly see the level of powder in the hopper, and more importantly, it is easy to replace the screw.

Disadvantage: Can’t see the state inside the hopper, poor quality.

Split Hopper

For some initial entrepreneurial customers, there are usually several or dozens of different dry powders. And the initial entrepreneurial customers do not have enough funds to buy different machines for different dry powder. For such dry powder packing manufacturers, an easy-to-clean auger filler machine will help them solve big problems and save manpower.

In addition, Split-hopper with high flexibility can meet the requirements of flexible production. It only takes 2 minutes if needs to replace the metering auger parts, which to realize the filling needs of different materials and different specifications. It will not affect the normal operation of the entire production line of the factory.

It is worth mentioning the conversion of the filling weight for the dry powders. One simple-direct operation mode depends on the professional operational interface. The operation comfort of the touch screen is better than the button control. And the operation mode of the touch screen should conform to the user’s operating habits.

Convert of Metering Weight

Filling Weight & Funnel Diameter

In addition, the range of filling weight is also worth considering. Because the diameter of the funnel determines the speed and accuracy of the filling. For example: We are familiar with the water faucets and their diameters have a difference. A water faucets with thick diameter have a fast flow rate, but have poor accuracy. A water faucets with thin diameter have a slower flow rate, but have higher accuracy. So, Vtops Machinery recommended diameter of the funnel (Diameter of Auger Fillers) is following:

Fill Weight	Recommended Diameter of Funnel
1g-5g	Customize
5g-10g	φ20mm – φ25mm
10g-50g	φ25mm – φ30mm
50g-100g	φ30mm – φ35mm
100g-500g	φ35mm – φ45mm
500g-1000g	φ45mm – φ55mm
1000g-5000g	φ55mm – φ65mm

Tips:

1, All funnels are replaceable with each other. If you have any questions, please do not hesitate to Contact us.

Accessories

According to the customer’s needs, different dry powders can be additionally equipped with dust device. And the auger accessories can be replaced when there is a need. And suitable for the filling of fine particles and ultrafine powder materials.
