Rifu Intelligent Unveils Food-Grade Rotary Cup Filling and Sealing Machine

Core Technological Breakthroughs: Rotary Architecture Empowers Efficient Production

1. Flexible Cup Feeding & Double Filling Heads Linkage System

• Human-Machine Collaborative Cup Loading Design: Adopting an open rotary cup holder track, it supports quick placement of multi-specification plastic cups (φ60-120mm, PP/PET materials), accommodating special shapes like round and square cups, improving manual cup loading efficiency by 40%. Equipped with a cup-missing automatic detection sensor, it prevents empty cup misfilling.
• Dual-Servo Quantitative Filling Technology: Equipped with two independent metering mechanisms:
  • Liquid Mode: Uses a servo-driven piston pump with a dynamic flow compensation algorithm, achieving a filling accuracy of ±1% (CV value) for fluids like yogurt and juice, with a single-head filling speed of 60 cups/minute.
  • Granular Mode: Employs dual-screw synchronous conveying for nuts, fruit granules (particle size ≤8mm), achieving a filling accuracy of ±2%, an 80% efficiency improvement over single-head filling.

2. Rotary Positioning Sealing System

• Film Color Mark Tracking Technology: A high-precision color mark sensor (detection accuracy ±0.3mm) integrated at the rotary sealing station 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 the pattern deviation problem in traditional linear sealing, improving packaging aesthetics by 50%.
• Constant-Temperature Heat Sealing Process: Using a servo-driven rotary die (temperature control ±2℃), it adapts to various materials such as aluminum film, PE film, and composite film. Combined with pneumatic pressure closed-loop control (pressure accuracy ±5N), the sealing strength reaches ≥6N/15mm, with a leakage rate <0.05%, meeting the 6-12 month shelf-life sealing requirements for foods.

3. Continuous Finished Product Output Design

• Star Wheel Cup Transfer System: A stainless steel star wheel dial synchronously conveys sealed cups to the conveyor line with a positioning accuracy of ±1mm, supporting seamless integration with downstream labeling and cartoning machines for fully linked packaging processes.

Food-Grade Compliance Design for Diverse Production Scenarios

• Clean Contact Materials: Material-contact components use food-grade 304 stainless steel and medical-grade silicone seals, with a surface roughness Ra≤0.8μm, supporting quick-detach cleaning and complying 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 holders, filling heads, and sealing dies within 20 minutes, compatible with production from 100ml yogurt cups to 500ml meal replacement shake cups, meeting the multi-SKU rapid changeover needs of food enterprises.
• Human-Machine Safety Protection: Equipped with infrared hand-guarding gratings, overload protection, and emergency stop buttons, with an emergency response time <0.1 seconds. The visual touchscreen (supporting Chinese/English switching) reduces manual operation risks.

Customer Validation: 80% Capacity Increase & Dual Optimization of Quality and Cost

• Capacity Breakthrough: Processing 16,000 cups per 8-hour shift (rotary two-cup mode), an 80% increase over traditional single-head filling lines, reducing labor from 7 to 2 operators and significantly lowering labor costs.
• Quality Control: Liquid filling volume deviation ≤±1ml for 100ml specification, granular material filling accuracy ±1.5%, sealing position deviation ≤0.5mm, leakage rate <0.03%—key metrics exceeding industry standards by 25% or more.
• Cost Optimization: Packaging cost per cup decreased from 0.16 RMB to 0.08 RMB, film material utilization increased from 80% to 96%, saving over 800,000 RMB in annual consumable costs (based on 6,000 cups/day production).

Industry Leadership: 20 Patents Building Technological Barriers

• Multi-Material Adaptation Technology: The self-developed dual-mode filling switching algorithm (Patent No.: ZL2024XXXXXX) enables one-click switching between liquid and granular filling modes, adapting to 98% of food materials, 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 Southeast Asia, the Middle East, and other regions.
• 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.
