The miniature granary is a cuboid granary formed by sealing and encircling four sides of granary boards. An upper cover seals and covers an upper part of the granary. A plurality of negative-pressure ventilators are mounted at an outer part on one side of one long granary board in the granary boards. Air inlets of the ventilators penetrate through the granary boards to extend to the granary and are communicated by virtue of a detachable horizontal ventilating pipe. A plurality of vertical air inlet pipes parallel to one another are communicated and mounted on an upper arm of the horizontal ventilating pipe. A negative-pressure air inlet is formed in an outer side of another long granary board in a position corresponding to the ventilators,. The invention innovates a technical system with functions of realizing tunnel differential pressure cooling and dehumidification at an earlier stage and realizing spontaneous air-conditioned moisturizing, insect prevention, mildew prevention, aging prevention, rat prevention and loss prevention at middle-late stages. A body of the miniature granary is composed of a plurality of pinch plate type granary board modules, is convenient and portable in assembly, disassembly and movement, and is applied to farmers and grain processing enterprises.1/3 10 \9\8 7 6 FIG. 1
