1. Overview
The Fully Automatic Donut Production Line is an integrated solution designed for mass production of various types of donuts, including yeast-raised donuts, cake donuts, mini donuts, filled donuts, and specialty shapes. It is widely used in commercial bakeries, frozen food factories, central kitchens, and OEM production lines.
The line supports automated processes for mixing, proofing, shaping, frying, cooling, coating, filling, and packaging — helping manufacturers improve productivity, consistency, and hygiene standards.
2. Production Process Flow
Ingredient Preparation → Mixing → Dough Forming → Proofing (for yeast donuts) → Frying → Oil Draining & Cooling → Glazing/Coating → Filling → Packaging
The workflow can be customized depending on the donut type (yeast or cake).
