Raw material preparing → flour mixing → conveying → extruding → core filling → cutting off → conveying → drying → oil spraying → flavoring → packing

Flour mixer: Mix the raw materials like corn flour, wheat flour and rice flour, etc. with a certain amount of water evenly and sufficiently.
2. Material loading machine: It is the screw type conveyor with an electric motor. Feed the mixed materials to the feeding hopper of the extruding machine to ensure the convenient and efficient loading.
3. Darin's double screw extruder: Choose the proper extruder according to the capacity. Raw materials fall into the extruding system from the feeding hopper. Under the function of high temperature and high pressure, the products are squeezed out. We can set different configurations for making different products.
4. Core filler: By the puff filling machine, the core materials are injected into the hollow tubular snack immediately after produced from the extruder. The core materials can be peanut butter, chocolate cream, maltose, etc.
5. Cut-off machine: It is used for cutting off the snack with core materials. The length can be adjusted from 2cm to 20cm.
6. Elevator: It delivers the snack to the oven.
7. Multi-layer Oven: The oven is mainly the electric type. Temperature is adjusted automatically from 0℃ to 200℃ through the control cabinet. There is a double-layer stainless mesh bag inside. The baking time is adjusted according to the speed. After baking, the main ingredients and core materials permeate each other, thus enhancing the flavor, reducing the moisture and prolonging the shelf time.
8. Flavoring Line: There are the octagonal drum, single drum, and double drum flavoring. According to the capacity and product characteristics, we also have oil spraying, sugar spraying and coating equipments for your choice.
