A chopper is a cutting machine that utilizes the high-speed rotation of a cutting blade to chop meat and auxiliary materials into minced meat or meat paste. It can also chop and mix auxiliary materials, ice flakes, water, and minced meat or meat chunks together to form a uniform emulsion. It is an important equipment used for processing fish mince products, oils, and protein emulsions. Depending on the processing technology, high-speed or vacuum type chopper can be selected to achieve better emulsification effect and reduce bubbles to enhance structural density for some products.
