The invention belongs to the technical field of fruit 
ripening acceleration, and particularly relates to a banana 
ripening acceleration device. To solve the problems of slow 
ripening acceleration andnon-uniform ripening acceleration of bananas, the following scheme is provided: the banana ripening acceleration device comprises a 
workbench, a ripening acceleration cylinder is fixed to the outer wall of the top of the 
workbench, two containing trays with the same size are arranged on the circumferential inner wall of the ripening acceleration cylinder, bulges which are evenly distributed are arranged on the outer walls of the tops of the containing trays, air outlet holes which are evenly distributed are formed in the outer walls of the bulges, an outer 
barrel is fixed to the circumferential inner walls of the containing trays, and an inner 
barrel is fixedly installed on the inner wall of the outer 
barrel. Bananas are placed on the bulges, an air inlet mechanism blows air upwards, the air enters a first reducing 
pipe, a ripening accelerator generated by apples in the inner barrel is blown away outwards, part of the ripening accelerator is diffused into the first reducing 
pipe and blown out upwards from air outlet holes, the bananas obtain the ripening accelerator uniformly, the ripening accelerator rushes into all parts of the bananas, the ripening accelerator is evenly distributed, the bananas are ripe simultaneously, and the product quality is high.
