Raw material filtering equipment for multi-vitamin peptide protein powder production

The utility model provides raw material filtering equipment for multi-vitamin peptide protein powder production, which comprises a stainless steel cylinder, a discharge pipe, an air inlet mechanism and a filtering mechanism, the stainless steel cylinder is connected with the air inlet mechanism and the filtering mechanism, the filtering mechanism is fixed on the inner wall of the stainless steel cylinder, and the discharge pipe is fixed in the middle of the stainless steel cylinder in a penetrating manner. The air inlet mechanism comprises a piston barrel, a fixing plate, a high-frequency air cylinder, a piston plate, a bubble pipe, a rubber backing ring, a hollow block, an anti-disengaging rod and an air suction pipe. Air flows from bottom to top in the bubble pipe, the air jacks up the hollow block to generate bubbles in milk, the bubbles penetrate through the filter plate to jack away impurities at the top of the filter plate, the milk can be stirred, the impurities can be cleaned, the flow speed of the mi
