The starch edible straw production line is an industrial and automatic production line that uses various starch, rice flour, konjac flour and other materials as the main raw materials to produce edible and environment-friendly tableware. The production line adopts the twin-screw extrusion process, which uses the temperature, pressure and shear force in the extrusion process to make the raw starch in the materials gelatinize and denature, and the gelatinized materials are extruded into tubes through the mold; The finished starch edible straw can be prepared through the production process of cooling, shaping, cutting, low-temperature drying, etc. The product is produced with food grade raw materials and food grade requirements. The main component of the product is starch, which is non-toxic, harmless, edible and biodegradable; After soaking in warm water, it will not dissolve for several hours, but will only absorb water and expand. It is one of the best substitutes for plastic straw. The production process of this production line is completed at one time from feeding to finished products, with high degree of automation, tight connection between equipment, no redundant configuration, and the main material is food grade stainless steel; The production line has a high degree of automation, stable product quality, continuous production (no less than 72 hours of continuous production), no waste, and low energy consumption; Support customized design and manufacturing, and fully cooperate with the production needs of customers.
