1.Raw material pretreatment process
Raw material pretreatment mainly includes the segmentation and rinsing of raw materials. The purpose of segmentation is to facilitate the next step of raw material crushing processing. The main purpose of rinsing is to remove water-soluble proteins and other substances that affect the quality of the raw materials, such as endogenous enzymes, residual blood, colored substances, residual fat, fishy substances, inorganic salts and residual bone chips, which hinder the formation of gelation in the meat paste, so as to improve the overall sensory quality of Rice-meat dumplings. When the rinsing water temperature is below 10 ℃ and the amount of water used is four times the mass of the raw meat, it is a pre-treatment process.
2. Meat crushing(Meat grinder operation)production processes
Before adding auxiliary materials and chopping ingredients to make minced meat, the crushing treatment of raw meat is a necessary process operation. Its purpose is to physically decompose large pieces of raw meat into smaller tissues for the next step of chopping, avoiding uneven mixing of raw materials, long chopping time, and high temperature during the next chopping process, which may affect the quality of the product. The key to the crushing process lies in temperature control and selection of crushing particle size. Therefore, the temperature is generally controlled below 10 ℃, and the appropriate crushing particle size is generally selected between 4-5mm.
3 pulping(Beating machine operation)production processes
In the production process of Rice-meat dumplings, beating is a very important process. There is a distinction between high-speed and slow beating. Generally, beef meatballs are made by beating the meat pulp at a slow speed, which is similar to manual beating. A fully enclosed slow Rice-meat dumplings beater is used to drive a large belt pulley through a small belt pulley to slow down and beat the meat pulp at a slow speed; Most people like pork meatballs will choose high-speed beating
4.forming(Rice-meat dumplings forming machine)production processes
After the meat is slurried, it is molded by the Rice-meat dumplings forming machine, and the balls and round balls are made according to different requirements. This process determines the beauty of the balls.
