The processing flow of the spring roll production line is efficient and automated, it can realize automatic mixing, grouting, baking, putting fillings on the thin dough sheet, frying and so on.
Spring rolls are a popular snack and appetizer in the world. These spring rolls are made by wrapping a filling of vegetables or meat in a thin pastry sheet and then frying it. For large-scale production requires the use of automatic spring roll lines, the specific processing flow is below.
Batter Preparation: The first step in the production of spring rolls is preparing the batter. The batter is made by mixing flour, water, and other ingredients such as salt and oil in a mixing tank. Then make a flowable smooth batter with no solids.
Filling Preparation: The next step in the production of spring rolls is preparing the filling. The filling can be made of a variety of ingredients such as vegetables, meat, seafood, and paste. The filling is usually prepared by cutting or shredding the ingredients and then mixing them together. Spices and seasonings can also be added to enhance the flavor of the filling.
Pastry Sheet Formation: Once the batter and filling are ready, the batter is fed into the storange tank. The baking pan of the spring roll sheet baking machine starts to rotate, and the batter is lifted to the vicinity of the baking pan through the grout pump. The batter flowing out of the injection nozzle is brought to the baking pan, and the batter forms a thin pastry sheet by rotating about 270°.
Filling and Rolling: The filling is then placed on the pastry sheet, then fold the two sides of the spring roll sheets so that the length of the spring roll is fixed. Finally, it is quickly formed into spring rolls through the friction between the conveyor belt and the rollers.
Packaging and Freezing: Put the rolled spring rolls into the bags and seal them. If the spring rolls are to be sold frozen, they are frozen using a freezer. The frozen spring rolls are then stored in a freezer at a temperature of around -18°C.
Spring Rolls Frying: If the spring rolls are to be sold as a ready-to-eat product, then the product can be fried in a continuous frying machine. Fry the spring rolls in oil for 3-4 minutes until the fried spring rolls are golden brown and taste crispy.
In conclusion, the fully automatic spring roll production line involves several steps, including batter preparation, filling preparation, pastry sheet formation, filling and rolling, packaging and freezing, and frying. By using automated machines and processes, large-scale production of spring rolls can be done efficiently and consistently, ensuring high-quality products that meet the demands of consumers.
