Abstract In modern biscuit production, the double-layered sheet biscuit production line, with its innovative structure and efficient production process, has become a key piece of equipment for improving production efficiency and product quality. Compared to traditional single-layered biscuits, double-layered sheet biscuits offer a richer and more multi-layered texture, giving consumers new choices in biscuit types. Based on the ideas and concepts of double-layered sheet biscuits, Wenva Machinery, in collaboration with our clients, has incorporated new technologies and ideas into its traditional shortbread and chewy biscuit production line, developing a double-layered sheet biscuit production line. This article aims to introduce in detail the working principle, technical advantages, and significant benefits of the double-layered sheet biscuit production line in terms of product taste, appearance, and packaging efficiency. The article also discusses the equipment's automation control, en
This article discusses common tunnel oven problems encountered in biscuit production, including inconsistent baking, underbaked products, and equipment malfunctions. It provides insights into the causes of these issues and offers practical solutions to avoid them. Best practices for tunnel oven operation, such as regular training and maintenance, are also highlighted to ensure efficient and high-quality biscuit production.
In industrial baking production, the tunnel oven length and its temperature zone structure are key technical factors that determine baking quality. A properly designed oven length directly affects the product’s residence time inside the oven, while multi-zone temperature control ensures stable heat distribution and proper product structure formation. Based on tunnel oven operating principles, this article systematically analyzes the relationship between oven length and baking time, the mechanisms of multi-zone temperature control, and the suitability of different tunnel oven structures for various baked products, providing technical guidance for food factories seeking to optimize baking quality.
