In the fast-paced modern lifestyle, donuts have become a beloved baked snack worldwide, cherished for their sweet taste and diverse shapes. From street-side dessert shops to global bakery chains, the demand for large-scale, standardized donut production is growing rapidly. Shanghai Hengguang Food Machinery proudly presents its Fully Automated Donut Production Line, a smart technological solution that disrupts traditional craftsmanship by enabling fully unmanned operations from dough preparation to finished product packaging.
Intelligent Dough Processing System
Precision Mixing: Equipped with a planetary mixer driven by a servo motor, the system uses a PLC control system to accurately adjust rotation speed and mixing time. This ensures ingredients like flour, yeast, sugar, and oil are fully integrated at a constant temperature, forming a dough with elasticity and avoiding texture inconsistencies caused by manual mixing.
Automatic Dividing & Proofing: Dough is transported via a vacuum suction device to a CNC dividing machine, which cuts it into standard portions with uniform precision. Mechanical arms then transfer the dough to a multi-layer rotating proofing chamber.
Fully Automated Shaping & Frying Line
Versatile Molding Dies: The line features interchangeable mold sets supporting over 10 classic shapes (round, heart-shaped, ring-shaped, etc.). High-frequency vibration molding technology produces hundreds of smooth-surfaced, uniformly thick donut blanks per minute.
Smart Frying System: The double-layer mesh belt fryer uses German imported heat-conducting oil for heating. Donut blanks move steadily through the frying zone on the mesh belt, with an automatic flipping mechanism ensuring even browning on both sides. This reduces energy consumption by 10% compared to traditional frying processes.
Flexible Production Capability
The line offers exceptional flexibility, with mold changes and process parameter adjustments taking just 30 minutes. This allows rapid switching between producing donuts, bagels, muffins, and other baked goods—truly enabling multi-functional use of a single machine. This reduces equipment idle costs and provides flexible, efficient production solutions for enterprises to meet diverse market demands.
