Description

Technical Field

[0001] This application belongs to the technical field of drying equipment, specifically relating to a general-purpose box dryer and drying method. Background Technology

[0002] Traditional grain and oil drying methods rely on sun-drying for preservation. This method is time-consuming, requires a large area, and is easily affected by weather changes. To improve drying efficiency, large-scale continuous and circulating grain and oil dryers are widely used in the drying field. These dryers can reduce losses during the drying process through precise temperature and humidity control, ensuring good quality and taste. However, these large-scale dryers require large warehouses and spaces during construction. During operation, the dried grain and oil materials need to be transported to a warehouse near the dryer for centralized processing, which consumes significant time and economic costs. To improve the flexibility, efficiency, and environmental friendliness of dryers, mobile dryers are increasingly being used in the grain and oil drying field, playing an increasingly important role in modern agricultural production. They not only improve the convenience of drying but also help farmers reduce losses caused by weather and other unforeseen factors. However, current mobile grain and oil dryers generally suffer from problems such as small processing capacity, limited machine size, and transportation difficulties, which urgently need to be addressed.

The grain and oil materials are then conveyed to the unloading port 18 via the upper lifting auger 16. The orientation of the unloading port 18 can be adjusted by extending and retracting the unloading rotary telescopic device 17 at different angles. During transportation, the unloading rotary telescopic device 17 can extend and retract to lower the height of the dryer body, facilitating transportation.

When the dryer moves, the trailer provides power to the chassis system, driving the dryer to be pulled to the grain and oil material drying operation area.

[0027] To reduce the load on the traveling wheels 2 when the dryer is stationary, support legs 1 are respectively installed at the front, middle and rear ends of the chassis main beam 6. The support legs 1 are equipped with a support leg lifting device 30 with lifting function, which can realize the overall lifting of the dryer.

Step 2: Move the mobile telescopic box dryer to the work area. According to the amount of material to be processed in Step 1, make reasonable telescopic control of the dryer. The power provided by the telescopic mechanism power unit drives the mobile telescopic mechanism track to control the telescopic movement of each drying chamber to meet the normal volume required for drying grain and oil materials. Step 3: The grain and oil materials processed in Step 1 are fed into the extended and retractable hopper 28 of the dryer by a loader. Step 4: The grain and oil material in the feeding hopper 28 in step 3 is driven by the power device 27 of the tubular chain machine. The chain 31 and chain segments 32 rotate repeatedly, and the grain and oil material is transported through the tubular chain telescopic sleeve to the grain loading channel 26 and then enters the drying chamber. Step 5: Dry the grain and oil materials in the drying chamber of Step 4. The drying system generates hot air that circulates in the drying chamber, transferring heat to the grain and oil materials to ensure even heat distribution and accelerate moisture evaporation. The entire drying process can be precisely controlled by the control system 12 to regulate temperature and time, and the moisture content of the grain and oil materials can be monitored in real time by the temperature and humidity sensor 9 to achieve efficient and uniform drying and effectively reduce the moisture content of the grain and oil materials. Step 6: Based on the moisture content of the grain and oil materials after step 5, set a reasonable tempering time, temperature, and relative humidity.

[0042] Maintain good ventilation in the tempering warehouse to allow moisture to escape, and turn the grain and oil materials over from time to time to avoid local compaction that leads to uneven drying, so that the moisture content of the grain and oil materials gradually becomes more even and the overall quality of the dried grain and oil materials is improved. Step 7: After reducing the moisture content of the grain and oil materials processed in Step 6 to the preset moisture content, transport them into the material storage warehouse through the grain unloading system. Step 8: After completing the processing of grain and oil materials in Step 7, the dryer can retract the materials to a certain volume through the chassis system and telescopic mechanism, and place them in a convenient parking position for use in the next operation.

After drying, the grain and oil materials are transported to the upper lifting auger (16) of the unloading system through the tube chain conveyor pipe (29).

5. A general-purpose box-type dryer according to claim 1, characterized in that: The telescopic mechanism (5) includes: a telescopic mechanism track and a telescopic mechanism power unit; Multiple telescopic mechanism tracks are respectively arranged below multiple drying chambers, and the telescopic mechanism power unit is connected to the telescopic mechanism track to provide power to the telescopic mechanism track.

6. A general-purpose box-type dryer according to claim 5, characterized in that: The drying system includes: a fan (13), a burner (14), a heat exchanger (15), and a wind chamber; The burner (14) is connected to the heat exchanger (15), the heat exchanger (15) is connected to the fan (13), the heat exchanger (15) transfers heat to multiple air chambers to dry grain and oil materials, and the multiple air chambers are powered by a telescopic power device to extend and retract synchronously with the multiple drying chambers.

7. A general-purpose box-type dryer according to claim 1, characterized in that: The chassis system includes: chassis components, support legs (1), wheels (2), and chassis main beam (6). The chassis assembly includes multiple chassis, all of which are located above the main beam (6) of the chassis. The support legs (1) and the wheels (2) are located below the main beam (6) of the chassis. The support legs (1) are equipped with a support leg lifting device (30) with lifting function.

8. A general-purpose box-type dryer according to claim 7, characterized in that: The number of drying chambers is the same as the number of chassis. The size of the multiple drying chambers increases sequentially according to the direction of expansion and contraction, and the height of the chassis increases as the size of the drying chambers increases.

9. A general-purpose box-type dryer according to claim 8, characterized in that: The control system (12) is connected to the temperature and humidity sensor (9) via a communication protocol. The temperature and humidity sensor (9) is installed in the drying chamber and is used to monitor the temperature and humidity data of grain and oil materials in real time and control the start and stop of the dryer.

10. A drying method, comprising a general-purpose box-type dryer according to any one of claims 1-9, characterized in that: Includes the following steps: Clean the grain and oil materials to remove impurities; Move the dryer to the work area and control the extension and retraction of the dryer through the telescopic mechanism (5) according to the amount of grain and oil materials to be processed. The cleaned grain and oil materials are fed into the feed hopper (28) of the dryer. The materials in the feed hopper (28) are transported to the drying chamber through the tubular chain conveyor system. The drying system generates hot air that circulates within the drying chamber, transferring heat to the grain and oil materials and drying them. During the drying process, the temperature and drying time of the drying chamber are controlled by the control system (12) and the moisture content of the grain and oil materials is monitored in real time. The tempering time, temperature and relative humidity are set according to the moisture content. After the moisture content of the processed grain and oil materials is reduced to the preset moisture content, they are transported into the material storage warehouse through the grain unloading system. After drying is completed, the dryer is folded up and stored using the chassis system and telescopic mechanism (5) for use in the next operation.
