[0002] Food coloring is an additive used for food coloring, the purpose of which is to improve the color and appearance of food and increase consumers' desire to buy. Grinding is the process of evenly mixing food coloring and other additives in food so that they are better dispersed in the food to improve the color and appearance of the food. During use, the existing food coloring special grinding equipment is not conducive to adjusting the width of the grinding channel, resulting in insufficient grinding and insufficient fineness, which in turn leads to low purity of the pigment extracted later.

In the public document, a baffle and a return spring are set to make the baffle fit with the first crushing roller and the second crushing roller. The operator drives the two crushing rollers to rotate relative to each other externally to perform preliminary grinding of the pigment. Then the servo motor drives the movable grinding part to rotate, and the interaction between the movable grinding part and the fixed grinding part is used to grind the raw materials. The operator can drive the movable grinding part to rise and fall through the cylinder, and then adjust the spacing between the grinding convex particles, thereby adjusting the width of the grinding channel to make the grinding sufficient and fine.
