Problems solved by technology

There are generally two major defects in this hot blast stove: 1) the heating temperature of each part of the grain is not uniform, and then causes the moisture content of the grain to be inconsistent, thereby bringing certain difficulties for the preservation of the grain; 2) the ventilation effect is relatively poor, which greatly reduces the limited drying effect

Abstract

The invention discloses an efficient hot-blast stove which comprises a housing, wherein a cavity is formed in the housing, the cavity comprises a drying cavity and two ventilation cavities; the two ventilation cavities are located at the two ends of the drying cavity; through holes are formed between the drying cavity and the ventilation cavities; the drying cavity takes the shape of a funnel that is wide at the upper part and narrow at the lower part; an air inlet is formed in a side wall of one ventilation cavity; an air outlet is formed in a side wall of the other ventilation cavity; a plurality of heating grooves and a plurality of containing grooves for containing grains are formed in the drying cavity at intervals; a plurality of air vents are formed in walls of the adjacent containing grooves and the heating grooves; a plurality of heating units are arranged in the heating grooves in a vertical direction; in addition, the power of the heating unit is sequentially reduced in a direction from air intake to air outgoing. The efficient hot-blast stove can dry the grains efficiently and uniformly, and a storage effect of the grains is improved.

Description

technical field [0001] The invention relates to a drying device, in particular to a high-efficiency hot blast stove. Background technique [0002] The hot air stove is used to provide hot air for drying, such as drying grains; according to the relative movement direction of grain and airflow, the hot air stove can be divided into cross flow, mixed flow, forward flow, countercurrent and forward and reverse flow, mixed and reverse flow, forward and mixed flow, etc. type. The most basic requirement of the hot blast stove is to reduce the moisture content of the grain to 10%-12% by weight. Only in this way can the grain be preserved for a long time, otherwise the grain will germinate or become moldy. [0003] Existing hot blast stoves directly arrange multiple heaters inside the device for heating, and then the hot air in the heaters is discharged into the grains through the heat exhaust unit to realize the drying of the grains. There are generally two major defects in this ho...
