The dry air after drying enters the drying tower 1 from the air inlet 11 under the action of the induced draft fan 8, and is discharged through the air outlet 9, as shown in the flow direction 7 of the dry air in fig. 1, a high-speed updraft is formed in the drying tower 1.
The feeding system comprises: the screw conveyor 4 and the material collecting and discharging opening 13; a feed inlet 2 of the screw conveyor 4 is arranged below; the discharge port 5 is arranged at the upper part and is communicated with the drying tower 1 at the upper part of the side wall of the drying tower 1; the collecting and discharging port 13 is located at the bottom of the drying tower 1 and is communicated with the drying tower 1. The dried fruit material to be dried enters from a feed inlet 2 of a spiral conveyor 4, is lifted by a conveying spiral and then is fed into a drying tower 1 from a discharge port 5, falls to the bottom of the drying tower 1 in the drying tower 1 and is discharged from a collecting and discharging port 13. The dry fruit material that waits to dry piles up at drying tower 1 bottom, forms the material and piles up 12, can prevent that outside air from gathering discharge gate 13 entering drying tower. Similarly, dry fruit materials to be dried enter from the feeding hole 2 of the spiral conveyor 4, are lifted by the conveying spiral and then are sent into the drying tower 1 from the discharging hole 5, and external air is prevented from entering the drying tower from the discharging hole 5.
The ultraviolet lamps 10 are vertically arranged in the center of the drying tower 1, the uppermost ends of the ultraviolet lamps are arranged below the position of the communication position of the discharge port 5 and the drying tower 1, and the position of the communication position of the air inlet 11 and the drying tower 1 is higher. The ultraviolet lamp 10 is positioned right in the process of falling of the dried fruit materials to be dried.
The inner wall of the drying tower 1 is plated with an ultraviolet reflecting film for reflecting ultraviolet rays emitted by an ultraviolet lamp and better irradiating dried fruit materials to be dried.
The driving motor of the induced draft fan 8 is a variable frequency motor, and is used for adjusting the rotating speed of the induced draft fan, so that the drying tower 1 is internally provided with proper air volume to enable dried fruit materials to be dried to be in a floating state and slowly descend; materials with too high wind speed can be blown to the air outlet 9 and even block the air outlet; the wind speed is too small, the falling of the materials is too fast, and the drying effect and the ultraviolet sterilization effect are not good.
The driving motor of the spiral conveyor 4 is a variable frequency motor, and is used for adjusting the rotating speed of the conveyor 4 so as to adjust the conveying capacity of the conveyor 4, so that the throughput of materials in the drying tower is controlled, and the best drying and sterilizing effects are achieved.
Be provided with material uniform distributor 6 in drying tower 1, material uniform distributor 6 is in below discharge gate 5 and the 1 intercommunication department position of drying tower and be in above ultraviolet lamp 10 topmost.

The working process of the vertical energy-saving dried fruit drying and ultraviolet sterilization device provided by the utility model is described in detail with reference to fig. 1.
The dried fruit material to be dried enters from a feeding hole 2 of a spiral conveyor 4 according to the direction shown by a material conveying direction 3, is conveyed into a drying tower 1 from a discharging hole 5 after being lifted by a conveying spiral, falls to the bottom of the drying tower 1 in the drying tower 1 and is discharged from a collecting and discharging hole 13. The dry air after drying enters the drying tower 1 from the air inlet 11 under the action of the induced draft fan 8, and is discharged through the air outlet 9, as shown in the flow direction 7 of the dry air in fig. 1, a high-speed updraft is formed in the drying tower 1. The dried fruit material to be dried enters the drying tower 1 and is dispersed by the airflow rising at high speed; when the dry fruit material particles to be dried fall, the falling speed is slowed down under the lifting action of the high-speed ascending airflow, and the dry fruit material particles roll due to the irregular shapes of the material particles. In the process that dry fruit material particles to be dried slowly descend and turn over in the drying tower 1, on one hand, the dry fruit material particles are dried better by dry air, and compared with the existing drying mode, the dry fruit material particles are dried more uniformly, the drying speed is accelerated, and the obvious energy-saving effect is achieved; meanwhile, the ultraviolet lamp can irradiate more uniformly, so that the sterilizing effect is achieved.
The dried fruit materials to be dried are stacked at the bottom of the drying tower 1 to form a block, so that external air can be prevented from entering the drying tower from the collecting and discharging port 13. Similarly, dry fruit materials to be dried enter from the feeding hole 2 of the spiral conveyor 4, are lifted by the conveying spiral and then are sent into the drying tower 1 from the discharging hole 5, so that air blocking is formed, and external air is prevented from entering the drying tower from the discharging hole 5.
The material uniform distributor 6 is arranged to enable dried fruit materials to be dried to be dispersed and fall more uniformly when entering the drying tower 1 from the discharge port 5. The driving motor of the induced draft fan 8 is a variable frequency motor, and is used for adjusting the rotating speed of the induced draft fan, so that the drying tower 1 is internally provided with proper air volume to enable dried fruit materials to be dried to be in a floating state and slowly descend; materials with too high wind speed can be blown to the air outlet 9 and even block the air outlet; the wind speed is too small, the falling of the materials is too fast, and the drying effect and the ultraviolet sterilization effect are not good. The appropriate wind speed.
The driving motor of the spiral conveyor 4 is a variable frequency motor, and is used for adjusting the rotating speed of the conveyor 4 so as to adjust the conveying capacity of the conveyor 4, so that the throughput of falling materials in the drying tower 1 is controlled; if the throughput is too large, the density is too large, and the best drying and sterilizing effect cannot be achieved; if the throughput is too small, the density is too small, the working efficiency is low, and the energy is wasted.
