This design facilitates auxiliary opening and closing after weighing feedback;

[0026] Furthermore, a mixer 110 is installed at the discharge port below the centralized mixing hopper 100, an aggregate inlet channel 120 is installed on the left side above the centralized mixing hopper 100, and an aggregate placement bin 130 is installed at the upper end of the aggregate inlet channel 120. The aggregate placement bin 130, the aggregate inlet channel 120, the centralized mixing hopper 100 and the mixer 110 are supported and assembled in sequence from top to bottom by a mixing building frame 140. This design facilitates the support and assembly of the centralized mixing hopper 100, making the batching operation more convenient.

[0027] Furthermore, the ice-making equipment 200 is supported and assembled by the steel frame building 150, and the height of the ice-making equipment 200 is level with the aggregate storage bin 130. The screw conveyor 210, the ice weighing bucket 220 and the belt conveyor 230 are supported and assembled by the steel frame building 150 from top to bottom.
