The production line of chocolate brownie chips (which have the rich chocolate flavor of brownies and the flaky form of cookies) needs to be combined with the standardized process of industrialized production of baked goods. The core is to achieve continuous operation of raw material processing, mixing, molding, baking, cooling and packaging through automated equipment, while ensuring the product taste (slightly crispy on the outside and moist on the inside) and flavor stability. The following is a detailed description of the production line process and key links: In the mixing stage, the pre-treated raw materials need to be mixed in order to form a uniform batter (different from cookie dough, the brownie base is closer to a "paste" and has medium fluidity). The key is to avoid excessive gluten formation of the flour (otherwise the taste will be hard) while ensuring sufficient emulsification of the oil, sugar, and egg liquid (to prevent stratification and oil release after baking).
