● Frequently Asked Questions (FAQ)
In modern industrialized baking production, the double-layer sheet biscuit production line, with its novel biscuit type, high efficiency, stable product quality, and intelligent operating system, has gradually become the preferred equipment for many biscuit manufacturers. Its unique double-layer structure not only improves production efficiency but also demonstrates significant advantages in taste, appearance, and packaging. This article will detail the double-layer sheet biscuit production line from multiple aspects, including its working principle, technological advantages, and application scope.
Double-layer sheet biscuits typically refer to biscuits composed of two thin sheets joined together. Customers can choose to add chocolate sauce or meat floss between the two layers. Compared to traditional sandwich biscuits with jam sandwiched between two thick sheets, double-layer sheet biscuits have a thinner, crisper biscuit base and a superior taste. Furthermore, double-layer sheet biscuits can be produced fully automatically on a single production line, unlike traditional sandwich biscuits which require additional equipment. The double-layer structure is formed through a specific process. This structure not only enhances the appearance of the biscuits, making them more aesthetically pleasing, but also effectively improves the taste and enhances the consumer's eating experience. Typical characteristics of double-layered cookies include:
Exquisite appearance: The double-layered structure creates a smooth, layered surface with excellent visual appeal.
Rich flavor: The layers between the two sheets offer more choices for fillings, resulting in a richer texture and flavor profile.
High adaptability: Suitable for producing various flavors and types of cookies, meeting the needs of different consumers.
With increasing consumer demand for high-quality, personalized products, double-layered cookies are becoming increasingly popular in the market. Double-layered cookies are a more innovative product, offering consumers a new choice among many traditional cookie types. Their crisp, delicious, and rich flavor is sure to appeal to consumers.
The core of a double-layered cookie production line lies in its complex yet efficient production process. The entire production process can be roughly divided into the following stages:
Dough preparation is the first step in the production line, typically including mixing, stirring, and fermentation. Raw materials such as flour, butter, sugar, and milk are precisely proportioned and mixed into dough using an automated system. Wenva machinery is also equipped with a fully automated flour supply system, eliminating the need for manual flour handling during the raw material feeding stage, reducing dust emissions, and ensuring the consistency of ingredient ratios. Operators simply unload bags of flour or starch into the feeding station; the system automatically screens, conveys, weighs, and delivers the raw materials directly to the dough mixer according to the ingredient ratio.

The core process of double-layered sheet cookies lies in the bonding of two different sheets on the production line. After pressing, the sheets are conveyed by two systems (upper and lower) in conjunction with a central material distribution section, and then bonded and cut into shape. Precise control of temperature, humidity, and pressure, along with accurate bonding during the rolling cut, ensures the thinness and layering of the sheets.

Using a tunnel oven, the double-layered sheet cookies are baked to perfection under precise temperature control. The optimal baking time and temperature ensure even heating of each layer, resulting in a beautiful golden-brown surface and maintaining their unique crisp texture.
After baking, the cookies are cooled to room temperature in the cooling zone to ensure structural stability. After cooling, the cookies are shaped into more uniform shapes by a sorting system, facilitating faster and more efficient packaging using automated packaging equipment.
Modern double-layer sheet cookie production lines typically employ high-precision automated equipment. From dough mixing, sheet pressing, baking to cooling and packaging, almost every step can be operated through intelligent control. This significantly improves production efficiency, reduces human error, and ensures product consistency and stability.

We have a professional R&D team and a stable installation and commissioning team, enabling us to quickly resolve and handle various problems encountered during production debugging and operation, ensuring more stable production and a longer service life during formal production and operation.
Compared to traditional single-layer biscuit production lines, double-layer sheet biscuit production lines incorporate an additional sheet transport system. The two layers are adhered together for shaping and baking, placing higher demands on the production line. The two layers must be precisely adhered and shaped to prevent splitting or deformation after baking. The production process is highly automated and precisely controlled, ensuring consistency in taste, appearance, and other quality indicators for each batch of products.
