Automatic SS Donut Forming Line​-for Ring Donuts & Berliners

Donut Production Line

Product Overview

The Juheng Automatic Donut Forming Line is a dedicated forming system that handles the critical shaping stages of donut production. From dough feeding through precision sheeting and cutter forming, this line outputs uniformly shaped donut pieces ready for transfer to external proofing and frying equipment.

The process is focused and efficient: dough enters from the mixer and passes through a sheeting station that reduces it to a uniform, precise thickness. The formed sheet then moves through the cutting station, where interchangeable tooling stamps out ring donuts, Berliner discs, donut holes, or custom shapes. Excess dough is automatically recycled back to the infeed, minimizing waste.

All food-contact surfaces are SUS304 stainless steel and other food-grade materials. The line is CE certified. Custom configuration based on your product type, size, and target capacity.

Product Features

Production Process – One Line, Two Product Types

Dough Feeding  

The dough is loaded into the hopper.

Multi‑Stage Sheeting  

Dough passes through sheeting rollers to form a uniform slab.

Dough Sheet Calibration  

A precision calibrator ensures even thickness across the entire sheet width.

Cutting – Select Your Cutter Plate

- For ring donuts: Install the ring‑shaped cutter plate. Each cutter simultaneously cuts the outer circle and removes the center hole, producing a donut ring and a separate “donut hole” (collected as by‑product).

- For berliners: Install the solid round cutter plate. Each cutter stamps out a solid dough disc with no center hole.

Scrap Dough Separation & Recycling

After cutting, the dough lattice (if any) is automatically lifted and separated. The scrap can be recirculated to reduce waste.

Panning

Finished products will be placed on trays automatically

Versatile Donut Style & Size Adaptability

Seamlessly switches between ring-style and berliner donuts without major mechanical adjustments, eliminating the need for separate equipment for different product types.

Easily adjustable settings for donut diameter and thickness, allowing quick transitions between standard, mini, or jumbo sizes to match customer preferences or seasonal promotions.

High-Volume Production Capacity

Optimized for high-speed output, with a capacity range of 3000-9000pcs/h (adjustable based on donut size and complexity). This makes it ideal for operations handling large orders (e.g., supermarket chains or bulk export).

Streamlined conveying systems minimize dough handling time, ensuring a steady flow from forming to the next production stage (e.g., frying, glazing, or cooling), reducing bottlenecks and maximizing efficiency.

Consistent Quality & Hygienic Design

Precision forming rolls and cutting mechanisms ensure every donut has uniform shape, size, and weight—eliminating irregularities that lead to customer complaints or product waste.

SUS304 stainless steel construction resists rust and corrosion, while smooth surfaces and detachable components make cleaning fast and thorough.

Applications

Frozen Donut Blank Manufacturers

Produce frozen, raw donut blanks (rings or berliners). Freeze immediately after cutting, then ship to bakeries that proof and fry from frozen.

Export-Oriented Enterprises

Serve international markets with different preferences (e.g., rings in North America, berliners in Europe) using a single line. Quick changeover allows you to run multiple SKUs.

FAQ

What determines the line’s exact production capacity?

Capacity is directly related to donut size and style.  Our team can provide a precise capacity estimate based on your specific product.

What information is required to customize the line?

To tailor the line to your needs, please share:

Target donut size (diameter, thickness, and weight).

Desired production capacity (hourly or daily output goals).

Factory layout (available floor space, integration with existing equipment like fryers or glazers, and utility access).
