A drying component 5 is arranged on the other side of the partition curtain 16 for drying the residual moisture of the basketed lettuce after blowing water by using high temperature blowing. A water collecting bucket 6 for collecting the blown away moisture is also arranged below the partition curtain 16.
[0014] The blowing assembly 4 comprises a breather 11, a first air blower 10, a first pipe frame 9, a manifold 8 and a first air nozzle 7, the first air blower 10 is arranged on the upper part of the frame 3 on the inner side of the cover body 1, which is the power source of the blowing assembly 4 and is used to generate high-pressure air flow, one end of the first air blower 10 is connected with the breather 11, the breather 11 has the functions of dehumidification and impurity removal, which can ensure that the air entering the first air blower 10 is dry and clean, avoiding secondary pollution to the lettuce, the frame 3 on the inside of the cover body 1 is further provided with the first pipe frame 9, which is a hollow structure and is sleeved outside the conveying belt 2, the first pipe frame 9 is in a square structure and is stably installed on the frame 3 to support and fix the subsequent manifold 8 and first air nozzle 7, one side of the first pipe frame 9 is connected with the first air blower 10 through a hose, so that the high-pressure air generated by the first air blower 10 can enter the inside of the first pipe frame 9 through the hose, the two sides of the first pipe frame 9 are uniformly and spacedly provided with the manifold 8 which is in communication with the first pipe frame 9 and extends outward in the circumferential direction, the design of the manifold 8 enables the high-pressure air to be uniformly distributed to each first air nozzle 7, ensuring that each part of the surface of the lettuce can be evenly blown, the first air nozzle 7 is arranged below the manifold 8, which is the terminal component of the blowing assembly 4 and is used to spray high-pressure air to the surface of the lettuce, so as to blow away the water floating on the surface of the lettuce, in the working process, when the cleaned basket filled with lettuce is conveyed to the blowing assembly 4 area by the conveying belt 2, the first air blower 10 is started and dry and clean air is sucked in through the breather 11, the high-pressure air enters the first pipe frame 9 through the hose, and then is distributed to each first air nozzle 7 through the manifold 8, the high-pressure air sprayed by the first air nozzle 7 directly acts on the surface of the lettuce, blowing away the water attached to the lettuce, in this way, most of the water on the surface of the lettuce can be quickly and effectively removed, preparing for the subsequent drying operation.
[0015] The drying assembly 5 comprises a heater 15, a second pipe frame 12, a second air nozzle 13 and a second fan 14. The second fan 14 and the second pipe frame 12 are arranged on the upper part of the frame 3 inside the cover body 1. The second fan 14 is the power source of the drying assembly 5 and is responsible for generating the required high-temperature air flow. In order to heat the air, the heater 15 is arranged inside the cover body 1, so that the air passing through the fan can be heated to the appropriate temperature. The second pipe frame 12 is also a hollow structure and is sleeved outside the conveying belt 2. Similar to the first pipe frame 9, the second pipe frame 12 is also a square structure and is stably installed on the frame 3. One side of the second pipe frame 12 is connected with the second fan 14 through a hose, so that the high-temperature air after heating can smoothly enter the inside of the second pipe frame 12 through the hose. A plurality of second air nozzles 13 are arranged in the circumferential direction of the second pipe frame 12 and are spaced apart. These second air nozzles 13 are connected with the inside of the second pipe frame 12 and can uniformly spray high-temperature air to the surface of the lettuce. The high-temperature air sprayed through the air nozzle can effectively dry the water remaining on the surface of the lettuce and further improve the drying degree of the lettuce. After the lettuce passes through the water blowing assembly 4 to remove most of the water, the conveying belt 2 will continue to convey it to the area of the drying assembly 5. At this time, the second fan 14 is started and the air sucked in is heated to the appropriate temperature through the heater 15. The high-temperature air after heating enters the second pipe frame 12 through the hose and is uniformly sprayed to the surface of the lettuce through the second air nozzle 13. Under the action of the high-temperature air, the water remaining on the surface of the lettuce will be rapidly evaporated, thereby realizing the rapid drying of the lettuce. Through the processing of the drying assembly 5, the lettuce can not only further remove the surface water, but also can achieve the effects of sterilization and preservation to a certain extent. The whole drying process has high automation degree and simple operation, which can significantly improve the production efficiency and ensure the quality and taste of the lettuce.
[0016] In use, first, the cleaned basket is placed at the starting end of the conveying belt 2, ensuring that the lettuce is evenly distributed in the basket, so that the subsequent draining process is more uniform and effective, the operator starts the drying device, the conveying belt 2 starts to move slowly, and the lettuce basket is brought into the cover body 1, at the same time, the water blowing assembly 4 and the drying assembly 5 also start to work, preparing for the next step of processing, when the lettuce basket enters the water blowing assembly 4 area, high-pressure air is uniformly sprayed to the surface of the lettuce through the air nozzle, this strong airflow effectively blows away the excess water on the lettuce leaves, achieving rapid and gentle surface moisture removal, then, the lettuce basket enters the drying assembly 5 area, where high-temperature air blows the lettuce evenly through the second air nozzle 13, making the residual moisture on the surface of the lettuce evaporate quickly, the drying process not only further improves the drying degree of the lettuce, but also helps to improve the sanitary quality of the lettuce, after the two steps of water blowing and drying, the lettuce has basically reached the requirement of draining, at this time, the conveying belt 2 transports the lettuce basket to the outlet end of the device, the operator can easily take out the drained lettuce for subsequent packaging or storage work. It should be noted that the power of the second fan 14 is less than that of the first fan 10, so as not to cause the lettuce to be over-dried under high temperature and high pressure.
