[0025] (1) The present invention provides a detachable silicone mold on the left and right pressing rollers, and then provides hemispherical mold cavities with different ball diameters on the silicone molds, so that meatballs of different specifications can be formed by replacing different silicone molds. Compared with existing equipment that can only produce meatballs of fixed specifications, the present invention has a wide range of applications, is very convenient to use, and has high flexibility;

In addition, the use of steam to ripen meatballs is cleaner and more hygienic;

[0027] (3) The present invention sets the cooling and freezing processes together, with cooling first and freezing later. After the meatballs are cooked, they are cooled first, which can effectively ensure the chewy texture of the meatballs. At the same time, it can also shorten the subsequent freezing time, saving energy and being environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS
