The whole assembly line consists of three parts which are forming, cooking and cooling, and is made of high-quality 304 stainless steel, which is easy to operate and maintain. The meatballs produced by the meatball machine fall into the forming tank to form, and then are transported by the conveyor belt to the cooking tank for further cooking, and finally enter the cooling tank for cooling. The heating source can be selected according to the actual situation of the customer, and steam heating is generally used. The automation of making meatballs is realized, the labor intensity is reduced, and the production efficiency is improved.
