These changes overlap during the baking process, but it is useful to note that the formation of the structure and texture of the biscuit will take place in the first and second temperature zone, the reduction in the moisture in the third temperature zone and the development of the color in the final temperature zone. The length of the baking oven depends on biscuit capacity customer wants. The length of the temperature zone depends on the biscuit. Different biscuit use different industrial biscuit oven. Common biscuit baking oven such as hybrid ovens and adjustable hot wind convection baking oven as below.
1.Hybrid ovens consists of direct gas-fired heating（DGF）, followed by convection heating toward the end of the baking process, contribute to produce a wide range of biscuit types. Different types of heat and moisture control can in fact have different effects on the final product.
2.Adjustable hot wind convection baking oven (DFC & IFC) use of hot wind circulation to heart the oven,can improve the biscuit’s bloating and make sure the surface of biscuit uniform color,is the unearthly baking oven for baking salt and sweet fermented biscuit.
