The fried puffed food production line uses rice flour, starch, wheat flour and other cereal flour as the main raw materials for production, and uses twin-screw extrusion and frying technology to process the raw materials into various leisure puffed foods, such as the commonly seen crispy fried rice crisps, salad bars, shell crisps, small fried dough twist, potato chips, potato chips and various 3D shaped products on the market; According to the process details, the above products can be classified into once puffed fried food and twice puffed fried food; The former does not need to be dried and fried directly after extrusion, and the product tastes crispy and hard, so the equipment scale is relatively small; The latter needs to add a low-temperature drying process after being made into billets by extrusion molding process. When the product moisture volatilizes completely, it will enter the frying link. During the frying process, the product will be expanded twice, with better expansion and crisp taste, but the equipment scale is relatively large. The production process of our company's fried puffed food production line is simple, and the whole process from raw materials to finished products is uninterrupted and continuous. The continuous operation time is not less than 72 hours, and there is no waste water or waste material discharged in the whole process; Its main equipment includes mixer (mixing raw materials), twin-screw extruder (extrusion and extrusion molding), shaping and cutting machine (auxiliary molding and cutting), dryer (moisture removal), fryer (frying to improve taste), spray flavoring machine (spray flavoring), etc; All equipment in contact with food shall be produced and processed with food grade materials that meet the requirements of food safety production. The whole line shall be customized in design layout. The supporting scheme and workshop layout shall be customized according to the actual needs of customers. The design output ranges from 100 kg to hundreds kg.
