China DPL Series Yeast Donut Production Line - Automatic Factory Solution by Top Suppliers

The DPL series donut line, designed for manufacturers in China, is an advanced solution for producing high-quality yeast-raised donuts with minimal manual input and maximum output. As one of the leading suppliers in the industry, our factory utilizes a fully automated process where donuts are cut directly onto proofing trays. These trays are efficiently transported through an electronically controlled proofer, ensuring optimal fermentation. Once proofed, the donuts proceed seamlessly to the fryer, with our proofer's speed synchronized to the fryer, glazer, and cooling conveyor, guaranteeing consistent quality in every batch. For higher capacities exceeding 2400 pieces, this line is equipped with a rolling cutter instead of an extruder for precision cutting. Choose our DPL series donut line for reliable and efficient production capabilities tailored to your business needs in China.

    Make-up and Forming (Cutting-Proofing-Injection-Glazing-Decorating)

    Cutting

    The extruder makes pressure-cut raised donuts efficiently. The Ring Cutter is for cutting donuts with hole; the Shell Cutter is for cutting donuts without hole. Adjustments can be made to the required donuts weights and sizes by changing the program and pressure, etc.

    Proofer

    By adjusting the humidity, temperature, and transfer time in the proofer, the donuts can be fermented well, producing round, beautiful, and delicious donuts.

    Injection

    If you want to produce filled donuts, you can purchase a filling machine according to your needs to make the flavors and types of sweets more diverse.

    Glazing

    A glazing machine can be equipped according to demand and fried donuts can be conveyed to it through a conveyor belt. The syrup in the glazing machine is recycled to make full use of the syrup without waste.

    Fryer

    DPL Series have two types of fryer. One is gas and the other is electric models. The whole production line is equipped with micro computer temperature and frying time controller, variable speed conveyor belt drive, excellent material, minimum maintenance, plc control and energy efficient.
