Piston-Type Quantitative Filling + Color Mark Pre-Positioning Technology Empower End-to-End Automation, Leading Dual Upgrades in Liquid Food Packaging Precision and Aesthetics
Guangdong Rifu Intelligent Equipment Co., Ltd. (hereinafter referred to as "Rifu Intelligent") announced today the official launch of its food-grade linear two-cup filling and sealing machine. Designed for liquid and semi-solid foods such as yogurt, juice, sauces, and jelly, the equipment realizes semi-automated production from empty cup loading to finished product output through four core processes: "manual cup placement-precise filling-UV sterilization-intelligent sealing". The core innovations lie in the piston-type quantitative filling system and color mark positioning sealing technology, integrated with a pre-printed production date system, addressing industry pain points such as insufficient liquid filling precision, sealing pattern deviation, and non-standard date labeling, to provide efficient, compliant, and aesthetic intelligent packaging solutions for small and medium-sized food enterprises.
- Human-Machine Collaborative Cup Loading: Featuring an open cup tray track with anti-slip positioning slots, it supports quick placement of multi-specification plastic cups (φ50-100mm, PP/PET/PS materials), improving manual cup loading efficiency by 30% and accommodating special shapes like round and square cups.
- Piston-Type Precision Filling Technology: Equipped with a servo-driven piston pump metering mechanism, it achieves precise filling of 5-500ml for liquid materials (viscosity 1-5000mPa·s, including suspensions with ≤5mm particles). Using a dynamic flow compensation algorithm, the filling accuracy reaches ±1% (CV value), a 50% efficiency improvement over traditional gravity filling, eliminating issues like dripping and bubbling.
- Tunnel-Type UV-C Sterilization Module: Embedded with 254nm wavelength UV-C lamps, providing an irradiation intensity ≥15mJ/cm², achieving a ≥99.9% bacterial kill rate on cup rims and liquid surfaces, complying with GB 14881 food hygiene standards without additional chemical disinfection.
- Thermal Transfer Ribbon Coding Technology: A high-speed thermal transfer ribbon coder integrated into the film feeding path prints production dates, shelf lives, batch numbers, and other information in real time. The coding speed matches the equipment operation speed (up to 60 times/minute), with a character clarity of 300dpi, ensuring clear and uniformly positioned date labeling after sealing.
- Film Visual Positioning Technology: A high-precision color mark tracking sensor (detection accuracy ±0.2mm) real-time captures positioning marks on the roll film, automatically calibrating the sealing die position to ensure complete alignment between film patterns and cup mouths. This solves traditional issues like pattern deviation and text truncation in random sealing, improving packaging aesthetics by 60%.
- Constant-Temperature Heat Sealing Process: Using a servo-driven constant-temperature die (temperature control ±2℃), it adapts to various materials such as aluminum film, PE film, and PET/PE composite film. Combined with pneumatic pressure closed-loop control (pressure accuracy ±5N), the sealing strength reaches ≥5N/15mm, with a leakage rate <0.05%, meeting the 6-12 month shelf-life sealing requirements for liquid foods.
- Clean Contact Materials: Material-contact components use food-grade 304 stainless steel and medical-grade PTFE-coated pipelines, with a surface roughness Ra≤0.6μm, supporting CIP (in-situ cleaning) and quick-detach disinfection, compliant with FDA 21 CFR Part 177, EU EC 1935/2004, and China GB 4806 food contact safety standards.
- Rapid Changeover Capability: The magnetic quick-release mold system enables specification switching of cup trays, filling pistons, and sealing dies within 15 minutes, compatible with production from 100ml yogurt cups to 500ml sauce cups, meeting the multi-SKU rapid changeover needs of food enterprises.
- Human-Machine Safety Protection: Equipped with infrared hand-guarding gratings, automatic cup-missing shutdown, and overload protection, with an emergency response time <0.1 seconds. The visual operation interface (supporting Chinese/English switching) reduces manual operation risks.
Testing by a leading 低温酸奶 (low-temperature yogurt) enterprise demonstrated outstanding performance:
- Capacity Breakthrough: Processing 14,400 cups per 8-hour shift (two-cup mode, 1,800 cups/hour), a 70% increase over traditional manual lines, reducing labor from 8 to 3 operators and significantly lowering labor costs.
- Quality Control: Filling volume deviation ≤±1.2ml for 100ml specification, sealing position deviation ≤0.3mm, production date printing pass rate 100%, leakage rate <0.03%—key metrics exceeding industry standards by 30% or more.
- Cost Optimization: Packaging cost per cup decreased from 0.18 RMB to 0.07 RMB, film material utilization increased from 82% to 97%, saving over 500,000 RMB in annual consumable costs (based on 5,000 cups/day production).
As a leading enterprise in China's intelligent packaging equipment sector, Rifu Intelligent relies on a provincial-level engineering technology research center and holds 15 packaging equipment invention patents, establishing three core advantages:
- Liquid Material Metering Technology: The self-developed dynamic viscosity compensation algorithm (Patent No.: ZL2023XXXXXX) automatically identifies material viscosity and adjusts filling parameters, adapting to 98% of liquid foods, including high-viscosity sauces and pulpy suspensions.
- International Compliance Capability: The equipment is certified to CE and ISO 22000 food safety management systems. A multi-language operation interface and FDA-compliant material certificates developed for export markets have successfully served dairy enterprises in Thailand, Turkey, and other countries.
- Full Lifecycle Service: Providing 7×24-hour remote fault diagnosis and 48-hour express response for critical components, with dedicated engineer regular inspections to ensure equipment utilization ≥95%, helping customers achieve "zero-downtime" production.
Adhering to the philosophy of "Flexible Manufacturing + Intelligent Control," Guangdong Rifu Intelligent Equipment Co., Ltd. has specialized in packaging equipment for food, healthcare, and daily chemical industries for 18 years, delivering over 5,000 intelligent production lines globally. Committed to independent innovation, the company invests over 15% of annual revenue in R&D, is a national-level specialized, refined, and innovative "little giant" enterprise, and is dedicated to providing global customers with "high-precision, high-flexibility, high-compliance" intelligent packaging solutions.
The launch of this linear two-cup filling and sealing machine marks a technological breakthrough for Rifu Intelligent in liquid food packaging. In the future, the company will continue to focus on cutting-edge technologies such as AI visual quality inspection and IoT cloud monitoring, driving the transformation of food packaging toward "precise metering, intelligent positioning, and data traceability" to help customers build more competitive product images in the consumption upgrade trend.
