The Development of Seasoning and Sauce Filling and Sealing Machines: Advancing Towards Intelligence and Flexibility
As a key component of food packaging machinery, the seasoning and sauce filling and sealing machine has undergone a development journey that profoundly reflects changes in market demand and advancements in industrial technology. From initially meeting basic packaging functions to today's integration of automation, informatization, and intelligent technologies, its evolution clearly points toward higher efficiency, superior quality, and greater flexibility.
1. Development Drivers: Market Demand and Technological Breakthroughs
Traditional sauce filling primarily relies on manual or semi-automatic equipment, leading to issues such as low efficiency, poor controllability of hygiene conditions, and low measurement accuracy. With the expansion of the consumer market and increasingly stringent requirements for food safety and quality consistency, automated filling and sealing machines have emerged. Their development is primarily driven by the following factors:
Efficiency and Cost: Mass production requires high-speed, continuous operations to reduce unit costs.
Hygiene and Safety: The improvement of food regulations drives the adoption of stainless steel materials that are easier to clean and free of hygiene dead corners, as well as designs compliant with GMP (Good Manufacturing Practice).
Product diversification: From thin vinegar and soy sauce to high-viscosity sesame paste and chili paste, and further to minced garlic paste with particles, the diversification of product characteristics poses a severe challenge to equipment adaptability.
II. Technological Evolution and Core Breakthroughs
To address the aforementioned challenges, the filling and sealing technology has achieved significant breakthroughs at multiple levels:
Precision and Diversification in Filling Technology
For sauces with varying viscosities, various filling principles have been developed, including piston, screw, and gravity-based methods. Among these, servo motor-driven piston and screw filling have become the mainstream for high-precision filling, ensuring highly consistent net content for each bottle of product.
For sauces containing particulates, the equipment achieves damage-free and uniform filling by optimizing valve and flow channel design.
The Reliability and Diversity of Sealing Technology:
The sealing methods have evolved from simple screw caps and crimping to heat-sealed films, electromagnetic induction sealing, and aluminum foil sealing, offering varying levels of sealing strength and ease of opening to meet the freshness preservation and anti-counterfeiting needs of different products.
The intelligence of control systems:
The control system has evolved from traditional relays and PLCs (Programmable Logic Controllers) to modern integrated servo systems, human-machine interfaces (HMIs), and industrial IoT (IIoT) technologies. Operators can easily set and switch recipes, monitor real-time production data, efficiency, fault alarms, and more, enabling traceability and management of production data.
