Accurate measurement and efficient packaging: Analysis of China's granule filling and sealing machine industry

In industries such as food, pharmaceuticals, chemicals, and daily chemical products, the demand for packaging granular materials (such as grains, seeds, pills, granules, snacks, feed additives, etc.) is huge and continues to grow. As the core equipment for achieving automated packaging, the technical level and market dynamics of particle filling and sealing machines directly affect production efficiency and product quality. Currently, the Chinese granule filling and sealing machine industry is rapidly developing towards high precision, high flexibility, and intelligence.

1、 Market demand drives technology segmentation

The vast manufacturing foundation in China provides a wide range of application scenarios for particle filling equipment. The driving force of market demand mainly comes from three aspects:

Consumer upgrade: The prosperity of markets such as leisure food, high-end pet food, and health food requires packaging equipment that can not only be efficiently mass-produced, but also meet the requirements of beauty, freshness, and diversified packaging forms.

Industrial standardization upgrade: Especially in the pharmaceutical and food fields, increasingly strict GMP (Good Manufacturing Practice) and food safety regulations have put forward higher requirements for equipment materials, ease of cleaning, and data traceability.

Rising labor costs: The urgent need for enterprises to reduce costs and increase efficiency has accelerated the process of "machine replacement" and promoted investment in automated and intelligent packaging lines.

It is worth noting that due to the significant differences in physical properties of granular materials (such as size, shape, specific gravity, and flowability, from micro powders to tablets to puffed snacks), the market's demand for filling technology is highly segmented, giving rise to specialized solutions for different materials.

2、 Technological Evolution: Balancing Accuracy, Speed, and Flexibility

To meet the complex and ever-changing demands, the technological evolution of domestic granule filling machines has focused on the following aspects:

Continuous improvement in measurement accuracy: Traditional volumetric measurement methods such as drum type and cup type are still widely used in general fields, and stability has been improved through structural optimization. For high-value materials such as drugs and high-end health products, the popularization of combination scales (computer combination scales) has become a key progress. It can effectively overcome particle differences and achieve extremely high measurement accuracy through intelligent combination calculation of multiple weighing units, and has become the mainstream configuration of high-end production lines in food and medicine.

Flexibility and modular design: In order to adapt to the market trend of "small batches and multiple varieties", the flexibility of equipment is crucial. The leading manufacturer adopts modular design, which enables one device to flexibly handle packaging bags of different sizes and types of granular materials by quickly replacing measuring modules, hoppers, molding machines, and sealing molds, greatly reducing product changeover time.

Intelligent integration and control: Modern granule filling and sealing machines have been deeply integrated into intelligent production lines. Through PLC (Programmable Logic Controller) and touch screen interface, operators can easily set parameters and monitor operating status. The equipment can collaborate with upstream feeders and downstream packaging robots, and achieve real-time recording and transmission of production data (such as output and fault information), providing support for digital management of the factory
