The invention discloses a beer brewing hops feeding mechanism which comprises a feeding cylinder. A material guide cylinder is arranged on the feeding cylinder, openings are formed in two ends of thematerial guide cylinder, an axis of the material guide cylinder is coincided with an axis of the feeding cylinder, the cross-sectional area of the material guide cylinder is gradually reduced along with the axis of the material guide cylinder far away from the feeding cylinder, a limit pipe is arranged at one end, close to the feeding cylinder, of the material guide cylinder, the thickness of thelimit pipe ranges from 1mm to 10mm, one end of the limit pipe is connected with the end surface of the material guide cylinder, the other end of the limit pipe is inserted into the feeding cylinder, the outer diameter of the limit pipe is matched with the inner diameter of the feeding cylinder, and the lower end surface of the material guide cylinder contacts with the upper end surface of the feeding cylinder. According to the mechanism, a middle material guide device is arranged between the feeding cylinder and a heating tank, so that the feeding cylinder cannot be directly placed on a feeding port of the heating tank, high quality of beer is ensured, and working efficiency is improved.
