[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] A riddle fruit cluster dryer comprises a vertical drying bin 1, the top and bottom of the drying bin 1 are respectively provided with a material inlet 8 and a material outlet 9, the two sides of the drying bin 1 are respectively connected with an air inlet chamber 2 and an air outlet chamber 3, the tops of the air inlet chamber 2 and the air outlet chamber 3 are lower than the height of the material inlet 8 of the drying bin 1, the air inlet chamber 2 and the air outlet chamber 3 cover the middle section and the bottom of the drying chamber, and dry the materials in the middle and lower sections of the drying bin 1.

[0023] The bottom of the drying bin 1 is tilted at a certain angle to form an angular structure, so that the bottom of the drying bin 1 has two high and low sides, and the high and low sides of the drying bin 1 are located on different sides of the drying bin 1 from the air inlet chamber 2 and the air outlet chamber 3. The discharge port 9 is arranged on the lower side of the drying bin 1, and a reversing wind hood 4 is installed at the bottom of the higher side of the bottom of the drying bin 1, and a fan 5 is installed in the reversing wind hood 4. A heat pump 6 is connected to the outside of the reversing wind hood 4, and the two ends of the reversing wind hood 4 are respectively connected to the air inlet chamber 2 and the air outlet chamber 3 to form a circulation channel. The heat pump 6 heats the wind in the reversing wind hood 4, and then drives the fan 5 to push the heated wind in the reversing wind hood 4 to the air inlet chamber 2, and then discharges it into the drying bin 1 to dry the material. The hot air completes the heat exchange with the material, and then the cold air is discharged from the air outlet chamber 3 into the reversing wind hood 4 to heat it again to complete the closed cycle, and the heat exchange is stable and efficient. Secondly, the drying bin 1 is vertical, with a small footprint and low construction cost.

[0024] Several groups of horizontally placed pentagonal boxes 7 are arranged in the drying bin 1, and the pentagonal boxes 7 are connected to the air inlet chamber 2 and the air outlet chamber 3 respectively. The upper end surface of the pentagonal box 7 is a triangular support surface, and the lower end surface of the pentagonal box 7 is in an open and closed state. The size of one end of the pentagonal box 7 is larger than the size of the other end, and it is set as a large and small end. The pentagonal boxes 7 are arranged in layers in the drying bin 1, and each layer is equipped with several groups of pentagonal boxes 7. The large and small ends of the pentagonal boxes 7 between adjacent layers are arranged in opposite order. The pentagonal boxes 7 play a supporting role inside the drying bin 1 to avoid the material being too thick and the efficiency of hot air drying being low. By supporting the material at different height layers and leaving gaps, the hot air can fully contact the material at different height layers, thereby improving the drying efficiency. Secondly, the pentagonal box 7 adopts the large and small end form, which can effectively enhance the fluidity of the wind and ensure smooth wind circulation in the drying bin 1. The pentagonal boxes 7 between adjacent layers are staggered in the vertical direction, which can stagger the materials and avoid material compaction.

[0025] Furthermore, movable air valves 10 are installed in the air inlet chamber 2 and the air outlet chamber 3, and the movable air valves 10 are vertically slidably connected to the tops of the air inlet chamber 2 and the air outlet chamber 3. The height of the air inlet and outlet can be adjusted, thereby improving the utilization rate of hot air and reducing the use cost.

[0026] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
