The vertical spiral powder packaging machine is a specialized device for automatic quantitative packaging of powdered and granular materials, widely used in the food, pharmaceutical, chemical, and cosmetic industries. It employs the principle of "spiral rotary feeding," where the rotating screw evenly pushes the material from the hopper into the packaging bag, achieving integrated operation of precise metering and automatic packaging.
The core component of this equipment is the spiral screw. After the material is poured into the hopper, it is evenly and stably pushed downwards to the discharge port under the rotation of the screw. By controlling the number of rotations or the time of the screw, the discharge amount can be precisely adjusted, thus achieving high-precision quantitative filling. Subsequently, the material falls into a pre-made bag or forming device, and the sealing device completes the packaging.
In terms of key features, this equipment first and foremost boasts the advantage of precise metering. The spiral feeding method is highly adaptable to powdered materials, and the metering accuracy can typically be controlled within ±1%, far exceeding that of manual or volumetric metering. Secondly, it has a very wide range of applications, suitable for various powdery materials such as flour, milk powder, coffee powder, grains, and small granular materials. Even for powders with poor flowability and a tendency to clump, the spiral structure can effectively push them without clogging. Thirdly, the equipment is highly automated, and can be equipped with automatic bag making, filling, sealing, coding, and cutting functions to achieve fully automated packaging. Touchscreen control allows for adjustable parameters and easy operation. Fourthly, the equipment is clean and hygienic; most parts in contact with materials are made of 304 or 316L stainless steel, meeting the hygiene standards of the food and pharmaceutical industries. The sealed structure design effectively reduces dust leakage, maintaining a clean workshop environment.
In terms of applicable scenarios, the vertical spiral powder packaging machine is particularly suitable for small and medium-sized bag packaging, with common packaging sizes ranging from 5 grams to 5000 grams. Typical applications include milk powder bags, coffee powder packets, protein powder sample bags, traditional Chinese medicine powder packaging, and seasoning powder packaging.
When selecting a vertical spiral powder packaging machine, pay attention to the following: screw material and diameter, which determine feeding speed and accuracy; hopper capacity, affecting feeding frequency; sealing method, commonly including back sealing, three-side sealing, and four-side sealing; and whether a printer or nitrogen filling device is required.
In summary, the vertical spiral powder packaging machine, with its high precision, high adaptability, and easy cleaning, has become one of the preferred equipment in the powder packaging field. If your product is in powder or granular form and needs to be bagged, this equipment is worth considering.
