Acid seed reactor in cotton seed machining

The invention discloses cotton seed machining equipment, and in particular relates to an acid seed reactor in cotton seed machining. The reactor comprises a reaction chamber (10) consisting of a cylindrical object with a feeding inlet (5) and a discharge hole (11), wherein the reaction chamber (10) is provided with a seed spreading mechanism and an acid supply mechanism; acid is distributed through an automatic control mechanism according to the seed flow at the feeding inlet (5) and the discharge hole (11). Compared with the prior art, not only can the acid be rapidly applied to the cotton seeds, but also the acid application uniformity is good, dependence on a stirring blade type stirring tank is reduced, damage to the cotton seeds is alleviated, and meanwhile the acid supply amount can be adjusted according to the seed amount, and moreover the equipment can be powered on and powered off at appropriate time, so that the reactor is energy-saving and environmentally friendly.
