Grinding device capable of controlling mixing amount of food additives

The utility model discloses a food additive mixing amount control grinding device which comprises a shell, a grinding machine is installed in the shell, a feeding cylinder is installed on the top of the shell, and a heat dissipation device is installed on one side of the shell. A guide pipe is connected to the bottom of the feeding cylinder, a clamping block is clamped to the middle section of the guide pipe, and a motor is installed at the top of the shell; different types of food additive materials are added into the feeding cylinder, the materials in the feeding cylinder enter the guide pipe through the bottom opening under the action of gravity, the clamping block clamped in the guide pipe plays a role in blocking the materials moving downwards, the clamping block begins to rotate at a constant speed under the driving of the motor, and the groove is formed in the center line of the clamping block, so that the materials can be fed into the feeding cylinder. When the groove and the guide pipe channel are lo
