Abstract

PURPOSE:To increase the amount of contained grain by joining the tank wall parts of the sides opposite to the oblique shelves sides and combinably providing a pair of cooling tanks wherein dry grain is contained in the inside and cooled. CONSTITUTION:The oblique shelves 1 and a discharge gutter 2 respectively described hereunder are provided to the bottom part. The oblique shelves 1 are provided downward to the inside from one side. The discharge gutter 2 receives grain falling from the oblique shelves 1 and discharges grain. A pair of cooling tanks 3 wherein dry grain is contained in the inside and cooled are combinably provided by joining the tank walls 4 parts of the sides opposite to the oblique shelves 1 sides. The discharge gutter 2 which receives grain falling from the respective oblique shelves 1 and discharge grain is provided by connecting the interval of the respective oblique shelves 1. Thereby the need for tilting the tank wall 4 of one side is eliminated and the amount of contained grain can be increased. For example, the installation area can be drastically reduced and erection layout is enhanced by constituting a pair of coolers and two-sets of dryers of one unit.
