Problems solved by technology

However, the volume of a single ordinary tower dryer is limited, and it cannot completely dry the grain to the storage standard at one time. If a higher drying tower is built to achieve grain drying by increasing the path where the grain falls, the cost will be greatly increased. Increase the burden on enterprises and farmers; In addition, to obtain high-quality drying quality, the temperature requirements in the tower are different in different drying stages, and the temperature in the drying tower is generally constant or fluctuates in a small range. There are multiple stages in the drying tower, so it is very difficult to control the temperature of different stages in a drying tower

Embodiment 1

[0013] Such as figure 1 As shown, a multi-tower continuous dryer includes at least two stages of drying tower mechanisms and a hot air generating and conveying mechanism that provides drying gas for each drying tower mechanism, and each stage of drying tower mechanism includes a drying tower And for the hoist 1 that transports grain to the corresponding drying tower, the grain input end of the hoist 1 of the next level is set correspondingly to the grain output end of the drying tower described in the upper level so that the drying capacity of the upper level is The dried grain in the drying tower is transported to the next drying tower.

[0014] There are three advantages of this design:

[0015] 1. Due to the limited volume of a single drying tower, the moisture content of the once-dried grain has not yet dropped to the storage standard, and it needs to be dried continuously. Therefore, the grain that has been dried by the previous stage passes through the elevator 1 It is...

Embodiment 2

[0021] The difference between Embodiment 2 and Embodiment 1 is that the hot air generating and conveying mechanism includes at least two hot air blowers 2, and each of the hot air blowers 2 is connected to the corresponding drying tower through an air duct so as to transport the drying air for the drying tower. dry gas. The advantage of this design is that multiple hot air blowers can be used to replace a total hot air blower, so that each of the hot air blowers 2 corresponds to each of the drying towers, so as to realize the supply of different hot air blowers 2. The temperature of the drying gas is also different, so that each drying tower can carry out targeted temperature-controlled drying according to the drying degree of the grain in it. The drying gas is the gas heated by the hot air blower 2 .

Embodiment 3

[0023] The difference between embodiment 3 and embodiment 2 is that: the grain output end of the drying tower includes a discharge port and a conveyor belt mechanism 6 located below the discharge port, and the conveyor belt mechanism 6 is connected to the lifting mechanism of the next stage. The grain input end of machine 1 is correspondingly set. Due to the large volume of the drying tower, the conveyor belt mechanism 6 is provided to facilitate the grain transmission between adjacent two-stage drying equipment.

Abstract

The invention provides a multiple-tower continuous dryer, comprising at least two stages of drying tower mechanisms and a hot air generating and conveying mechanism for providing drying gas for each drying tower mechanism. Each stage of drying tower mechanism comprises a drying tower and an elevator for conveying grains to the corresponding drying tower; and a grain input terminal of a lower stage of elevator is arranged corresponding to the grain output terminal of an upper stage of elevator, so as to conveniently convey the dried grains in an upper stage of drying tower to a lower stage of drying tower. The multiple-tower continuous dryer has the advantages of scientific design, sufficient drying time, low cost, grading temperature supply, good drying effect and high drying efficiency.

Description

technical field [0001] The invention relates to a dryer, in particular to a multi-tower continuous dryer used in the edible grain drying process. Background technique [0002] The tower dryer is a commonly used drying equipment in the grain drying industry. Its drying principle is: the grain enters from the upper feeding port of the drying tower, and the grain is discharged between the multiple sets of hot air pipes and exhaust pipes in the tower. The grains are zigzagging and falling, using the heat of the hot air pipe to dry the grains, and then discharged from the bottom of the tower. However, the volume of a single ordinary tower dryer is limited, and it cannot completely dry the grain to the storage standard at one time. If a higher drying tower is built to achieve grain drying by increasing the path where the grain falls, the cost will be greatly increased. Increase the burden on enterprises and farmers; In addition, to obtain high-quality drying quality, the temperat...
