Is the double-funnel powder quantitative packaging machine fast in packaging speed?

The packaging speed of the double-funnel powder quantitative packaging machine is influenced by multiple factors such as material characteristics, weighing accuracy requirements, and equipment performance, resulting in significant variations. The typical range is between 200 and 1000 packages per hour. The specific situation is as follows:

I. Core Structure of Double-Hopper Powder Quantitative Packaging Machine

Automatic weighing device: It adopts high-sensitivity sensors (such as weighing modules) and intelligent control algorithms to ensure that the weight error of each bag is controlled within ±0.1% - 0.5%. It supports dynamic weighing, adapts to the differences in powder fluidity, and avoids overloading or underweighting.

Conveyor system: It is responsible for transporting materials from the weighing system to the packaging system. The height of the conveyor frame and guardrails of some equipment can be adjusted, and the guardrails are made of stainless steel.

Sealing device: It is used to seal packaging bags. The height adjustment is convenient. It also comes with an electric control box and safety protection functions.

Computer control system: It controls the operation of the entire equipment, ensuring the stability and accuracy of the production process. It features automatic correction of drop, automatic tracking of zero point, over-shoot detection and suppression, and can also automatically count the number of packages and the volume of packaging.

II. Common Packaging Speed Ranges

Conventional speed range: For the quantitative range of 25kg to 2 tons per bag, the mainstream dual-hopper powder quantitative packaging machines typically operate at a speed of 300 to 450 bags per hour, suitable for ordinary powder materials in industries such as chemicals and building materials (e.g., paint powder, lime powder).

High-speed range: Some equipment is specifically designed for small package sizes. For instance, models with a packaging range of 0.5-10kg can reach a speed of 1,000 packages per hour; equipment for packaging 15-80kg items can handle approximately 600 bags per hour; and models for 5-25kg packages can package 400 bags per hour. Such equipment is usually equipped with efficient feeding structures (such as double-screw feeding) and intelligent control systems, and is suitable for powders with good flowability (such as flour and feed powder).

Low-speed range: For special powders that are prone to clumping and have poor fluidity (such as certain pharmaceutical intermediates and highly hygroscopic powders), or in scenarios where extremely high precision is required (with an error of ±1 gram or less), the speed may drop to less than 200 packages per hour. This requires reducing the feeding speed and adding a weighing calibration step to ensure accuracy.

III. Core Factors Affecting Packaging Speed

Material characteristics: Powders with good fluidity and uniform particle size (such as milk powder and starch) can pass through the feeding and weighing system quickly, achieving higher speeds; powders that are prone to caking and have high viscosity (such as certain chemical additives) are likely to block the discharge port, requiring frequent cleaning or low-speed feeding, which will reduce the speed by 30% to 50%.

Weighing accuracy requirements: High-precision demands (such as in the pharmaceutical and high-end food industries) will limit the speed. For instance, when the error requirement is ±0.1%, slow feeding correction must be adopted, and the speed is 20% - 30% lower than that of equipment with conventional accuracy (±0.5%). However, for materials with low precision requirements such as fertilizers and mineral powders, production capacity can be increased by raising the feeding speed.

Equipment configuration: The response speed of sensors and the performance of the control system directly affect the speed. Equipment equipped with C3-level high-precision sensors and intelligent PLC control systems can quickly process weighing data and dynamically adjust the feeding, which is 15% - 25% faster than that of ordinary sensor equipment. The feeding structure also affects the speed. Three-speed feeding (fast, medium, and slow) is more accurate than two-speed feeding, but the speed is slightly lower. While double-screw feeding increases efficiency by about 30% compared to single-screw feeding.

Packaging specifications: For small-sized packaging (such as 0.5 - 10kg), due to the small amount of each weighing and discharging, the cycle period is short and the speed is much higher than that of large-sized packaging (such as over 50kg). For instance, the speed of 10kg per package could be 2 to 3 times that of 50kg per package.
