Double-Layer Biscuit Production Line

A double-layer biscuit production line is advanced biscuit manufacturing equipment that produces biscuits with two distinct layers — contrasting or complementary in texture and flavor — and can add a filling such as chocolate, cream, or meat floss between them.

Product Overview

It is built for manufacturers creating differentiated, premium-positioned products that stand out on crowded retail shelves. Wanttone’s double-layer biscuit production line automates the complete process from precision ingredient dosing and dual dough preparation through layered forming, baking, filling, cooling, and packaging.

Double-layer biscuits succeed or fail on adhesion: the two dough layers must bond perfectly during baking, or the product delaminates in the pack. Wanttone’s layered forming technology controls sheet thickness, moisture, and contact pressure so the layers fuse reliably at full line speed. Combined with automatic dosing accurate to within 0.5% and enclosed negative-pressure conveying that keeps the plant dust-free, the line runs a genuinely complex product with a crew of just 6–8 operators — turning a labor-intensive specialty biscuit into a profitable industrial product.

Capabilities & Applications

Key Features

  • Reliable Layer Adhesion

    Precisely controlled forming pressure and sheet moisture ensure the two layers bond completely during baking, eliminating delamination complaints.

  • Product Differentiation

    Create crispy-plus-soft, sweet-plus-salty, or two-flavor combinations, optionally with chocolate, cream, or savory fillings, for distinctive premium SKUs.

  • Precision Ingredient Dosing

    Automatic weighing and dosing with ≤0.5% accuracy guarantee recipe consistency and reduce raw-material giveaway.

  • Minimal Labor Requirement

    Full automation from mixing to packaging means the entire line needs only 6–8 operators per shift, sharply reducing labor cost for a complex product.

  • Dust-Free, Hygienic Plant

    Enclosed negative-pressure pneumatic conveying keeps flour dust contained, improving food safety and working conditions.

  • Flexible Filling Options

    Interchangeable filling systems handle chocolate, cream, jam, and meat floss, letting one line serve multiple product launches.

Applications

  • Double-layer biscuits with contrasting textures or flavors, filled sandwich-style premium biscuits (chocolate, cream, beef/meat floss), co-extruded-style specialty biscuits, and innovative SKUs for brands competing on novelty. Best suited to mid-sized and industrial biscuit manufacturers, snack brands launching premium lines, and contract manufacturers producing for major retail chains.

From Preparation to Packing

  1. Product Preparation

    Confirm the recipe, material condition and batch sequence required for stable production.

  2. Forming & Primary Processing

    Configure the product geometry and process conditions around the agreed finished product.

  3. Thermal or Main Process

    Coordinate time, temperature, energy and line speed with the target output and quality.

  4. Cooling & Finishing

    Stabilize and finish the product before downstream handling and packing.

  5. Packing Handover

    Deliver the product in the orientation, spacing and condition required by the agreed pack format.

The Wanttone Difference

Double-layer and filled biscuits demand coordination between dough technology, forming mechanics, and baking science — exactly the intersection where Wanttone’s dual strength matters most. As both an equipment builder since 1981 and an operating biscuit manufacturer, we have produced layered and filled biscuits commercially on our own machinery, so we advise you on recipes and process windows that actually work at scale. Our ISO 9001-controlled manufacturing, in-house machinery research institute, and track record supplying China’s leading biscuit groups mean your project is engineered by a team that has solved these problems before. From factory design and dosing-system configuration to commissioning, operator training, and lifetime after-sales support, Wanttone delivers the complete package for premium biscuit innovation.

Frequently Asked Questions

How do you guarantee the two layers do not separate after baking?

Layer adhesion is controlled by sheet moisture balance, forming pressure, and the baking curve. We tune all three during commissioning trials with your actual recipe, and lock the parameters into PLC recipes for repeatable results.

What fillings can the line handle?

The filling system handles chocolate, cream, jam, peanut butter, and viscous savory fillings such as meat floss. Filling quantity is precisely metered and can be adjusted per SKU from the touchscreen.

Is the dosing system really accurate to 0.5%?

Yes. Automatic load-cell weighing with ≤0.5% dosing accuracy is standard on major ingredients. This protects recipe consistency across shifts and reduces costly over-dosing of premium ingredients like butter and chocolate.

Can the line make single-layer biscuits too?

Yes. The layered forming section can be bypassed or reconfigured to run conventional single-layer biscuits and sandwich biscuit bases, giving you a flexible asset rather than a single-product machine.

How many people are needed to run and maintain the line?

A typical shift needs 6–8 operators including packing staff. Routine maintenance is handled by one trained technician; we train your team during commissioning and supply maintenance schedules and spare-parts lists.
