The fruits and vegetables are placed on movable shelves for placing fruits and vegetables, and then the shelves are pushed into the drying room. High-temperature hot air is filled into the drying room to dry the fruits and vegetables. When drying fruits and vegetables in the current fruit and vegetable drying room, the hot air is relatively light and usually flows upward, which causes the temperature at the bottom of the drying room to be relatively low, resulting in low drying efficiency of fruits and vegetables located on the bottom plate of the drying room, and the airflow effect of the hot air in the drying room is poor, which reduces the efficiency of the hot air flow in carrying away the evaporated water vapor, causing more water vapor to remain in the drying room, resulting in uneven drying of the fruits and vegetables in the drying room.

[0019] In order to make the objectives, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings for the convenience of those skilled in the art to understand.

[0020] As Figure 1-6 shown, the present invention provides a fruit and vegetable drying room for uniform drying, including a drying room main body 1. A basement 3 for placing a hot air blower 2 is arranged below the drying room main body 1. A plurality of ventilation holes 101 communicating with the basement 3 are uniformly opened on the floor in the drying room main body 1; the hot air blower 2 is installed in the basement 3. The air inlet of the hot air blower 2 is communicated with the outside through a pipeline, and the air outlet blows hot air into the basement 3. The hot air blows upward into the drying room main body 1 from the ventilation holes 101 on the floor, so that the fruits and vegetables located at the bottom in the drying room main body 1 can also be fully dried. Push the shelf loaded with fruits and vegetables into the drying room main body 1, close the drying room, and start the hot air blower 2 located in the basement 3. The hot air blower 2 sucks the outside air into the hot air blower 2 for heating and then blows the hot air into the basement 3. The hot air blows upward through the ventilation holes 101 on the floor and blows into the drying room main body 1 from bottom to top to dry the fruits and vegetables in the drying room main body 1, avoiding the situation that the hot air in the traditional drying room is difficult to reach the fruits and vegetables at the bottom of the drying room, so that the fruits and vegetables at the bottom cannot be fully dried. Through this structure, the hot air can evenly reach the bottom of the drying room, so that the fruits and vegetables in the drying room are evenly dried, improving the effect of fruit and vegetable drying.

[0021] Two blowing devices 4 for evenly dispersing the hot air blown out from the hot air blower 2 in the horizontal direction are installed in the basement 3. The two blowing devices 4 are respectively installed at the lower left and upper right of the hot air blower 2, and the blowing directions are opposite. Since the hot air is blown out from the hot air blower 2 concentratedly and cannot automatically diffuse around; the blowing devices 4 arranged on both sides of the hot air blower 2 disperse the hot air blown out from the hot air blower 2 horizontally, so that the hot air evenly flows upward, making the entire drying room main body 1 evenly filled with hot air to dry the fruits and vegetables evenly.

[0022] Three groups of blowing devices 4 are installed in the drying room main body 1, and each group of blowing devices 4 is arranged by installing single blowing devices 4 side by side; The first group of blowing devices 4 and the second group of blowing devices 4 are vertically installed on the left side inside the drying room main body 1, and the second blowing device 4 is installed on the side wall of the drying room main body 1 above the first group of blowing devices 4; The third group of blowing devices 4 is installed on the right side inside the drying room main body 1, and its installation height is between the first group of blowing devices 4 and the second group of blowing devices 4; The first group of blowing devices 4 and the second group of blowing devices 4 blow air to the right, and the third group of blowing devices 4 blows air to the left. After the hot air blows upward from the basement 3 into the drying room main body 1, the first group of blowing devices 4 and the second group of blowing devices 4 on the left blow air to the right, and the third group of blowing devices 4 blows air to the left. Since the height of the third group of blowing devices 4 is between the first group of blowing devices 4 and the second group of blowing devices 4, an air flow that circulates left and right is formed in the drying room main body 1, which is convenient for taking away the water vapor in the fruits and vegetables and accelerating the drying of the fruits and vegetables.

[0023] A condenser is installed on the top of the drying room main body 1. The air inlet end of the condenser 5 is connected to the air outlet of the top of the drying room main body 1 through a pipeline, and the water outlet pipe of the condenser 5 is connected to the water storage tank 6 arranged on the side of the drying room. The condenser 5 condenses the water vapor in the gas discharged from the drying room main body 1 and collects it in the water storage tank 6. The hot air passing through the drying room main body 1 takes the water vapor of the fruits and vegetables out of the drying room with the air flow and enters the condenser 5. The condenser 5 condenses the water vapor in the hot air into liquid water and stores it in the water storage tank 6 for use, thus playing the role of resource recycling and saving resources.

[0024] A drying box 7 is also installed on the top of the drying room main body 1. The drying box 7 is filled with desiccant. The air inlet end of the drying box 7 is connected to the air outlet end of the condenser 5 through a pipeline, and the air outlet end of the drying box 7 is connected to the air inlet of the hot air blower 2 located outside, so that dry air enters the hot air blower 2 for heating. The hot air passing through the condenser 5 has condensed most of the water vapor into liquid water. The air flowing out of the condenser 5 passes through the drying box 7, and the desiccant in the drying box 7 absorbs the remaining water vapor in the air, so that the formed dry air enters the hot air blower 2 in the basement 3 again for heating to take away the water vapor in the fruits and vegetables. The dry and heated air can take away more water vapor in the fruits and vegetables, thereby improving the drying effect of the fruits and vegetables.

[0025] A multi-folded heating pipe 8 is installed in the water storage tank 6. The two ends of the heating pipe 8 are respectively connected to the air outlet at the top of the drying room body 1 and the air inlet of the condenser 5. The hot air discharged from the drying room body 1 passes through the heating pipe 8 to heat the water in the water storage tank 6 before flowing into the condenser 5. The hot air discharged from the drying room body 1 is still very hot. The hot air flows through the heating pipe 8, raising the temperature of the heating pipe 8 and heating the condensed water in the water storage tank 6. The waste heat of the hot air is thus reused, improving heat utilization and conserving thermal energy resources. The hot air flowing through the water storage tank 6 then enters the condenser 5 to condense water vapor into liquid water. The hot air then flows into the drying box 7 to absorb the remaining water vapor before entering the hot air blower 2 for heating before entering the drying room.

[0026] The drying box 7 houses a desiccant storage frame 9, with evenly spaced sidewalls of the frame 9 providing airflow. A lid 701 is hingedly attached to the top of the drying box 7, fitted with a rubber sealing ring that secures the drying box 7 tightly. Air flowing out of the condenser 5 enters the drying box 7 and flows through the holes 901 in the sidewalls of the frame 9 into the desiccant. The desiccant absorbs moisture from the air, and the dried air then flows back into the hot air blower 2. When the desiccant reaches saturation with moisture, the frame 9 can be removed, the desiccant replaced, and then loaded back into the drying box 7, facilitating replacement. Rubber sealing rings are provided between the lid 701 and the drying box 7 to prevent air leakage.

[0027] The blowing device 4 includes a fixed cylinder 401 extending horizontally, fan blades 402, and a motor 403. The fixed cylinder 401 is fixedly connected to the bottom or side wall of the drying room body 1 via a support rod. The motor 403 is mounted on a fixing plate 404 provided in the fixed cylinder 401, and the fan blades 402 are mounted on the output shaft of the motor 403. The motor 403 drives the fan blades 402 to rotate, thereby blowing air and forming an airflow. The fixed cylinder 401 serves to guide the airflow.

[0028] Working process: Push the shelves with fruits and vegetables into the drying room main body 1, close the drying room, start the hot air blower 2 located in the basement 3, the hot air blower 2 draws the outside air into the hot air blower 2 for heating, and then blows the hot air into the basement 3. The hot air blown out by the hot air blower 2 is blown horizontally by the blowing devices 4 arranged on both sides of the hot air blower 2, so that the hot air flows evenly upwards. The hot air is blown into the drying room main body 1 from bottom to top through the vents 101 on the floor to dry the fruits and vegetables in the drying room main body 1. The first and second blowing devices 4 on the left side blow to the right, and the third blowing device 4 blows to the left, so that the hot air in the drying room main body 1 forms a left-right circulating airflow, which is convenient for taking away the moisture in the fruits and vegetables and speeding up the drying of the fruits and vegetables; the hot air discharged from the drying room main body 1 flows through the heating pipe 8 to heat the condensed water in the water storage tank 6. The hot air flowing through the water storage tank 6 enters the condenser 5 to condense the moisture into liquid water, and then flows into the drying box 7 to absorb the remaining moisture and then enter the hot air blower 2 to be heated and enter the drying room, thereby forming air circulation and saving resources; the fruits and vegetables in the drying room are dried evenly, and the drying effect of the fruits and vegetables is improved.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
