The invention discloses drying equipment for fermented feed. The drying equipment comprises a primary drying bin, a drying platform, a first hot air device, a secondary drying bin and a first conveying pipeline. The drying platform is arranged in the primary drying bin, and multiple evenly-distributed air outlets which are through up and down are formed in the drying platform. The first hot air device is used for supplying hot air to the drying platform from bottom to top through the air outlets. The secondary drying bin is cylindrical, and comprises an inner bin and an outer sleeve. The innerbin is sleeved with the outer sleeve, an annular cavity is defined between the outer sleeve and the inner bin, and multiple evenly-distributed vent holes are formed in the barrel wall of the inner bin. A second hot air device communicates to the annular cavity through a hot air pipeline, and on one cross section, the outer edges of the vent holes are basically tangent to the inner wall of the inner bin. Three heating walls are arranged in the inner bin and divide the internal space of the inner bin into three sector-shaped drying cavities. One end of the first conveying pipeline communicatesto the upper portion of the primary drying bin, and the other end of the first conveying pipeline communicates to the lower portion of the inner bin. The fermented feed can be prevented from being caked, and the drying efficiency is improved.
