Fully automatic pellet packaging machines are widely used in various industries. The following are the specific scope of application and common quantitative methods:
Scope of Application
- Food Industry: It is used for packaging various food particles, such as sugar, salt, MSG, chicken essence, rice, grains, nuts (peanuts, melon seeds, pistachios, etc.), dried fruits (raisins, dates, etc.), snacks (puffed food, fried food, shrimp crackers, etc.), and tea.
- Pharmaceutical Industry: It is suitable for packaging granular drugs, such as granules, capsules, and some solid preparations.
- Chemical Industry: It can be used to package chemical particles, such as plastic particles, fertilizer particles, feed particles, and some chemical raw materials.
- Other Industries: It is also applicable to the packaging of granular materials in industries such as daily chemicals (e.g., laundry detergent particles), pesticides, and seeds.

Quantitative Methods
- Measuring Cup Measurement: This method is based on volume measurement. The measuring cup is filled with pellets, and the volume of the pellets is used to determine the packaging quantity. It is suitable for loose - shaped, non - viscous granular materials, and is often used for the packaging of bulk - sold materials with low accuracy requirements, such as the loose - sold grab bags seen in supermarkets. Its advantages include simple operation and low equipment cost; however, its accuracy is relatively low.
- Combination Scale Measurement: The combination scale consists of multiple scales. Through intelligent calculation and combination, it can achieve high - precision weighing and metering. It has a high degree of intelligence and high metering accuracy, but the price is relatively expensive. Moreover, the more combinations the scale has, the faster the packaging speed will be. It is suitable for various granular materials, especially those requiring high - precision packaging.
- Linear Scale Measurement: The weighing principle of the linear scale is similar to that of a balance scale. It is particularly suitable for packaging large - weight materials and materials smaller than soybeans, such as some small - particle chemical raw materials or food additives. It can achieve higher accuracy in a specific weight range.
- Screw Scale Measurement: The screw scale is mainly applicable to materials that are not easy to vibrate or are prone to accumulation, such as ice cubes and ice grains. The screw rotates to transport the material, and the weighing is realized by controlling the rotation speed and time of the screw. This method can ensure relatively stable weighing results for some special materials.
