The Automatic Donut Sorting Packaging Line developed by Hengjiang Intelligent Technology Co., Ltd is a high-efficiency robotic packaging solution designed specifically for modern food production environments. By integrating high-speed Delta robots with high-precision SCARA robots, this system achieves seamless donut sorting, alignment, layered placement, and box packaging in a fully automated workflow. Designed to meet the growing demand for consistency, hygiene, and productivity, the line significantly reduces manual handling while ensuring uniform packaging quality and operational stability.
The donut sorting packaging line automates the complete secondary packaging process after frying or freezing. Incoming donuts are detected and picked by Delta robots, which rapidly grip individual products and arrange them into a precise single-row configuration on a side conveyor belt. This organized transfer ensures smooth downstream handling and eliminates product overlap or misalignment.
SCARA robots then take over, transferring the aligned donuts into cardboard boxes lined with food-grade plastic bags. Between each row of donuts, the system places greaseproof paper using SCARA-assisted positioning, preventing sticking, deformation, and oil migration. Once packed, the boxes are conveyed to subsequent sealing, labeling, or palletizing stations, making the line ideal for continuous, high-volume production.
This system combines speed, precision, and hygienic design to meet industrial food packaging standards. Delta robots provide ultra-fast picking and sorting, making them ideal for handling soft or irregularly shaped donuts without damage. SCARA robots offer superior repeatability and controlled motion, ensuring accurate placement inside boxes and consistent layering.
The entire line features a modular structure, allowing flexible configuration based on production capacity, box size, and donut variety. Food-contact components are made from food-grade materials, and smooth surfaces support easy cleaning and sanitation. Advanced vision systems and intelligent control software enable real-time tracking, error detection, and adaptive operation, ensuring stable performance even under fluctuating production conditions.
The Automatic Donut Sorting Packaging Line can be customized to match specific factory requirements. Typical specifications include high-speed Delta robot sorting capacities suitable for continuous production lines, SCARA robots with multi-axis precision for layered packaging, and conveyor systems designed for gentle food handling.
The system supports multiple donut sizes and packaging formats, with adjustable box dimensions and configurable layer counts. Integrated vision systems ensure accurate recognition and positioning, while centralized PLC and HMI control allow operators to monitor production status, adjust parameters, and perform diagnostics efficiently. Power consumption and footprint are optimized to balance performance with energy efficiency and space utilization.
Operation begins by feeding donuts onto the main conveyor, where the vision system identifies position and orientation. Delta robots pick and sort the donuts, aligning them into a single row on the side conveyor. The SCARA robots then transfer donuts into prepared boxes, placing greaseproof paper between layers as programmed.
Operators can manage the system via a user-friendly HMI interface, allowing quick changeovers for different donut types or packaging formats. Routine maintenance includes cleaning food-contact parts, inspecting grippers and sensors, and checking lubrication points. The modular design simplifies maintenance and reduces downtime, while remote monitoring options support efficient troubleshooting and technical support.
This robotic packaging line is widely applicable across the food processing and bakery industries, particularly for donut manufacturers, pastry factories, and frozen bakery product producers. It is also suitable for central kitchens, large-scale food distribution centers, and OEM food packaging operations requiring standardized output.
Beyond donuts, the system can be adapted for similar products such as bagels, buns, pastries, and other soft baked goods, making it a versatile automation solution for companies seeking to upgrade or expand their packaging capabilities.
The target customers include medium to large-scale bakery manufacturers, industrial food producers, and brand owners seeking to improve production efficiency, reduce labor dependency, and ensure consistent packaging quality. The system is also ideal for factories aiming to meet stricter food safety regulations and international hygiene standards.
Automation integrators, food equipment distributors, and enterprises planning smart factory upgrades will also benefit from this solution, as it offers scalability, reliability, and long-term cost optimization. By adopting Hengjiang’s Automatic Donut Sorting Packaging Line, customers gain a competitive edge through intelligent manufacturing and stable, high-quality output.
