Three-Roll Dough Sheeter

The three-roll dough sheeter receives prepared dough and forms a continuous sheet for the laminator or gauge-roll section of a hard-biscuit or cracker line.

Product Overview

It performs primary sheeting; downstream gauge rolls reduce the sheet in stages to the thickness needed for cutting. The sheeter exit thickness, roll settings and relaxation arrangement are selected around the dough and complete forming route.

Capabilities & Applications

Key Features

  • Primary Sheeting Before Gauging

    Three Ø300 mm rollers arranged in T-form press the dough into a continuous sheet for the laminator or gauge rolls. The initial exit thickness is selected for the dough and downstream reduction stages.

  • Relaxation in the Forming Route

    Dough relaxation is arranged within the sheeting and gauging route to help manage processing stress before cutting. Its position and duration depend on the dough and line design.

  • Precision Gap Control

    The roll gap is measured by a displacement sensor with an accurate digital display; speed and dough thickness are adjusted from the touch screen for repeatable, recipe-based settings.

  • Independent Roller & Belt Drives

    The rollers and the conveyor belt are driven by separate motors with frequency conversion, making fine speed matching between stations quick and easy.

  • Heavy-Duty, Hygienic Construction

    Q235 carbon-steel side plates (28 mm) and conveyor frame (15 mm) are hard-chrome plated to HRC58-62 surface hardness; dough-contact pallets are 304 stainless steel, and the enclosure uses 1.5 mm 304 stainless steel.

  • Food-Grade Conveying

    A European PU belt (1.3 mm) with Ø160 mm rubber-covered drive rollers in non-toxic, oil-resistant rubber ensures gentle, contamination-free dough transfer.

Applications

  • The three-roll dough sheeter sits directly after the dough mixer and feeding conveyor in hard biscuit, soda cracker, Marie biscuit, and thin crispy biscuit lines. It feeds a continuous sheet to the laminator or gauge roll section and is equally at home in new turnkey lines or as a capacity upgrade in existing plants producing tough-dough products.

A Defined Role in the Line

  1. Upstream Requirements

    Confirm the incoming material or product condition, target throughput, infeed height and available utilities.

  2. Core Machine Function

    Three Ø300 mm rollers arranged in T-form press the dough into a continuous sheet for the laminator or gauge rolls. The initial exit thickness is selected for the dough and downstream reduction stages.

  3. Downstream Integration

    Match discharge height, line speed, control signals, guarding and cleaning access with the next operation.

The Wanttone Difference

Wanttone’s predecessor, Yangjiang Biscuit Equipment General Factory, built its first dough sheeters in 1981 — and we have refined hard-biscuit sheeting ever since. What sets us apart is that we do not only manufacture the machine: we run our own biscuit factory on Wanttone equipment, and this production experience informs our approach to roller geometry, gap settings and downstream sheet reduction. Our in-house Foodstuff Machinery Research Institute continuously improves roller surface treatment and drive synchronization, while ISO 9001 quality control governs every plate, roller, and weld. When you buy a Wanttone sheeter, you gain 40+ years of process knowledge, commissioning support, and lifetime after-sales service — from a partner who sheets dough every day.

Frequently Asked Questions

What biscuit types is a three-roll dough sheeter used for?

It is primarily used for hard, tough-dough products: soda crackers, Marie biscuits, hard sweet biscuits, and thin crispy biscuits. Soft, high-fat doughs are normally formed directly by a rotary moulder instead.

How is dough relaxation arranged in a sheeting line?

Relaxation is planned within the sheeting and gauging route to help manage dough stress before cutting. The required arrangement depends on the recipe, reduction stages and product trials.

How is the primary sheet thickness selected?

It is set around dough consistency, the incoming feed and the reduction required downstream. Gauge rolls then bring the sheet to the cutting thickness; final settings are confirmed by product trials.

What is the difference between a three-roll sheeter and a gauge roll?

The three-roll sheeter performs primary sheeting — turning bulk dough into a continuous sheet. Gauge rolls then reduce that sheet in controlled steps to the final thickness before cutting. Both work together in a hard biscuit line.

Can this sheeter be integrated into my existing production line?

Yes. Widths, discharge heights, and control interfaces are customizable to match your current laminator, gauge rolls, or rotary cutter. Our engineers provide layout drawings and on-site commissioning.
