Application and Development of Blister Packaging Machines in the Jam Industry

For high-viscosity, particulate liquid foods like jam, blister packaging machines have some unique application and technological features. The following are their core application characteristics and development trends in the jam industry:

I. Core Application Characteristics

Dedicated Filling System: Utilizing piston-type filling or special pouring valves to address the high viscosity and particulate characteristics of jam, a jacketed heating function can be optionally added to prevent jam solidification and ensure smooth filling.

High Hygiene Standard: Components in contact with the jam (such as hoppers and filling nozzles) are generally made of 316L stainless steel and designed for easy disassembly and cleaning, eliminating dead corners and meeting food safety standards.

Flexible Forming and Sealing:The equipment uses a flat-plate structure for heating and forming, suitable for various materials such as PVC, PET, and PP, ensuring uniform blister thickness without dead corners. During sealing, a photoelectric correction system ensures precise alignment of the colored film pattern with the blister.

II. Technological Development Trends

1. High-Precision Servo Control: Shifting from traditional mechanical transmission to servo motor drive, controlling filling volume (accuracy up to ±0.5%) and traction stroke, adapting to more blister pack sizes, and enabling faster changeovers.

2. Intelligent and Visual Inspection: Integrating PLC and human-machine interface, capable of storing hundreds of product parameters. An integrated machine vision system detects filling volume, sealing quality, and defects in real time, automatically rejecting defective products.

3. Multi-functionality and Modularization: Equipment design is trending towards modularity. By changing molds and filling systems, it can quickly switch between different products such as jam, butter, and honey, and even be compatible with solid packaging, improving equipment utilization.

4. Cold Forming Technology Application: For some oxygen-sensitive jams, high-end equipment is beginning to support aluminum-aluminum cold forming packaging, which can be deep-stretched without heating, providing ultra-high barrier properties to extend shelf life.

Whether you are considering specific production capacity requirements (such as how many plates per minute) or packaging specifications (such as cup capacity and cup type), this information will help you further focus on more specific equipment selection recommendations.
