Description

Technical Field

[0001] This utility model relates to the field of blueberry processing technology, and more specifically to a blueberry washing and drying device. Background Technology

[0002] Blueberries, as a high-value fruit rich in anthocyanins, vitamins and various trace elements, are easily contaminated with dust, soil and pesticide residues during harvesting and transportation. Therefore, blueberries are washed. After washing, a lot of moisture remains on the surface of the blueberries. If they are not dried in time, the residual moisture can easily breed bacteria, accelerate the spoilage of blueberries, shorten their shelf life, and cause many inconveniences for subsequent processing, packaging and storage.

[0003] Currently, when blueberries are air-dried after washing, the rigid conveyor belts used to transport them often damage the fruit during transport, affecting its integrity and appearance and increasing the defect rate. Therefore, developing an air-drying device that can reduce fruit damage has become an urgent technical problem to be solved in the current blueberry processing field. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a blueberry washing and drying device to solve the problem that the fruit is easily damaged during transportation, which affects the integrity and appearance of the fruit and increases the defect rate.

[0005] This utility model provides the following technical solution: a blueberry washing and drying device, including a base frame, a cover fixed to the top of the base frame by bolts, a mesh conveyor belt fixed on the base frame between the cover and the base frame, a sponge pad tied to the outer circumference of the mesh conveyor belt by cable ties, an air inlet on the top of the cover, a fan frame fixed between the inner walls of both sides of the cover below the air inlet, the fan frame being composed of multiple fans, and a squeezing roller rotating between the two sides of the base frame below the mesh conveyor belt, the top of the squeezing roller squeezing the sponge pad below the mesh conveyor belt for drainage of the sponge pad.

[0006] As a further embodiment of this utility model, at least one slide is slidably connected between the inner walls of the two sides of the cover. The bottom of the slide is inclined, and a silicone strip is adhered to the side of the inclined surface facing the mesh conveyor belt.

[0007] As a further embodiment of this utility model, lead screws are welded to both outer walls of the slide, and the same number of guide grooves as the slide are opened on both sides of the cover. One end of the lead screw passes through the guide groove and slides in the guide groove. A nut is threaded to the outer circumference of the lead screw.

[0008] As a further embodiment of this utility model, a washer is provided between the nut and the cover, the washer is sleeved on the outer circumference of the lead screw, and both sides of the washer are in contact with the nut and the cover respectively.

[0009] As a further embodiment of this utility model, a mounting frame is provided below the fan frame and fixed between the inner walls of multiple sides of the cover, and a filter screen is provided on the inner walls of multiple sides of the mounting frame.

[0010] As a further embodiment of this utility model, a windproof cloth fixed on the mounting frame is provided below the filter screen, and the windproof cloth has multiple ventilation holes.

[0011] As a further embodiment of this utility model, the bottom of the cover is fixed with two baffles by bolts, and the two baffles are located on both sides of the sponge pad.

[0012] As a further embodiment of this invention, a water tank fixed on the base frame is provided below the mesh conveyor belt for the collection of wastewater.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the combination of sponge pad and squeezing roller, can prevent the fruit from being damaged by excessive moisture and provide stable and flexible protection for the blueberries during subsequent transportation, effectively improving the integrity of the fruit during transportation and reducing the defect rate.

[0014] 2. This utility model, through the cooperation of the slide and the silicone strip, can gently contact the surface of blueberries, gently separate the stacked fruits, and avoid damage to the skin caused by the fruits squeezing each other.

[0015] 3. By incorporating a windproof cloth, this utility model can divert and buffer the airflow generated by the fan frame, dispersing the originally concentrated strong airflow into multiple gentle airflows. This ensures sufficient airflow to achieve the drying effect while avoiding the problem of the fruit rolling, colliding, or even falling off the sponge pad due to the direct impact of excessively strong airflow on the blueberries. This further improves the stability of the drying process and the protection of the fruit. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4 This utility model provides a blueberry washing and drying device, including a base frame 1, a cover 2 fixed to the top of the base frame 1 by bolts, a mesh conveyor belt 4 fixed to the base frame 1 between the cover 2 and the base frame 1, a sponge pad 6 tied to the outer circumference of the mesh conveyor belt 4 by cable ties, an air inlet on the top of the cover 2, a fan frame 10 fixed between the inner walls of both sides of the cover 2 below the air inlet, the fan frame 10 being composed of multiple fans, a squeezing roller 5 rotating between the two sides of the base frame 1 below the mesh conveyor belt 4, the top of the squeezing roller 5 squeezing the sponge pad 6 below the mesh conveyor belt 4, and a water tank 3 fixed to the base frame 1 below the mesh conveyor belt 4. When in use, place the blueberries on the sponge pad 6 of the mesh conveyor belt 4. The mesh conveyor belt 4 will move the blueberries forward. Because the sponge pad 6 is soft and has a certain elasticity, it can cushion and protect the blueberries, avoiding mechanical damage caused by direct collision between the traditional rigid conveyor belt and the fruit. When the blueberries enter the enclosure 2 along the conveyor belt, multiple fans on the fan frame 10 start simultaneously, drawing in outside air from the air inlet and forming a downward airflow to perform preliminary air drying on the blueberries during the conveying process, removing some of the moisture attached to the surface of the fruit. Meanwhile, the squeezing roller 5 located below the mesh conveyor belt 4 continues to rotate, and its top continuously squeezes the lower surface of the sponge pad 6, causing the water absorbed by the sponge pad 6 during the blueberry transportation process to be squeezed out. The water drips along the gaps in the mesh belt into the water tank 3 preset at the bottom of the frame 1, keeping the sponge pad 6 dry and ensuring that the blueberries transported later can still receive good cushioning and water absorption protection, effectively maintaining the integrity of the blueberry fruit and reducing the defect rate caused by damage. By combining the sponge pad 6 with the squeezing roller 5, the fruit will not be damaged by excessive moisture, and the blueberries will be continuously and stably protected during subsequent transport. This effectively improves the integrity of the fruit during transport and reduces the defect rate.

[0023] It should be noted that the mesh conveyor belt 4 is existing technology, including a drive motor, a drive roller, a driven roller and an annular mesh belt. Its working principle can be learned by those skilled in the art through technical manuals, and will not be elaborated on here.

[0024] In this utility model, at least one slide 8 is slidably connected between the inner walls of the two sides of the cover 2. The bottom of the slide 8 is inclined, and a silicone strip 14 is bonded to the side of the inclined surface facing the mesh conveyor belt 4. During the process of blueberries being transported by the conveyor belt, the silicone strip 14 at the bottom of the carriage 8 can gently contact the surface of the blueberries, gently separating the stacked fruits and avoiding damage to the skin caused by the fruits squeezing each other. Meanwhile, the softness of the silicone strip 14 will not scratch the blueberry skin, and it can ensure that the fruit is arranged more evenly during transportation, which will facilitate subsequent sorting, packaging and other processes, thereby improving the processing quality of blueberries in the overall process.

[0025] Furthermore, lead screws 12 are welded to both outer walls of the slide 8. The cover 2 has the same number of guide grooves 11 as the slide 8 on both sides. One end of the lead screw 12 passes through the guide groove 11 and slides in the guide groove 11. A nut is threaded to the outer circumference of the lead screw 12. A washer 13 is provided between the nut and the cover 2. The washer 13 is sleeved on the outer circumference of the lead screw 12, and both sides of the washer 13 are in contact with the nut and the cover 2 respectively. After adjusting the height of the slide 8, when it is necessary to fix the height of the slide 8, tighten the nut on the screw 12 so that the washer 13 fits tightly against the outer wall of the cover 2. Through the thread locking force of the nut and the screw 12 and the increased friction of the washer 13, the slide 8 is fixed firmly at the current height position, preventing the slide 8 from shifting due to vibration during the operation of the device, and ensuring that the silicone strip 14 can always contact the blueberries at a suitable height and continue to play the role of spreading the fruit evenly. This height-adjustable design allows the device to adapt to blueberries of different sizes and ripeness. By adjusting the height of the slide 8, the distance between the silicone strip 14 and the conveyor belt can be changed, avoiding poor material feeding or damage to the fruit due to large differences in fruit size, thus improving the versatility and applicability of the device.

[0026] Furthermore, a mounting frame 9 is provided below the fan frame 10 and fixed between the inner walls of multiple sides of the cover 2. The inner walls of the mounting frame 9 are provided with filters 15. The filters 15 are made of high-density non-woven fabric, which can effectively filter dust, impurities and fine particles in the air, prevent these pollutants from adhering to the surface of the blueberries with the airflow, and ensure that the fruit is not contaminated during the drying process. Meanwhile, the detachable design of the filter 15 facilitates regular cleaning and replacement, preventing the filter 15 from becoming clogged after long-term use and affecting ventilation efficiency, ensuring a stable and long-lasting airflow effect for the fan holder 10, and providing a clean airflow environment for the blueberry drying process.

[0027] Below the filter 15 is a windproof cloth 16 fixed to the mounting frame 9. The windproof cloth 16 has multiple ventilation holes, which are evenly distributed in a matrix. The size of the holes is optimized to divert and buffer the airflow generated by the fan frame 10, dispersing the originally concentrated strong airflow into multiple gentle airflows. This ensures sufficient airflow to achieve the drying effect while avoiding the problem of the fruit rolling, colliding, or even falling off the sponge pad 6 due to the strong airflow directly impacting the blueberries. This further improves the stability of the drying process and the protection of the fruit.

[0028] Furthermore, the bottom of the cover 2 is fixed with two baffles 7 by bolts. The two baffles 7 are located on both sides of the sponge pad 6, which can play a lateral limiting role for the blueberries during the conveying process, preventing the blueberries from sliding to both sides under the influence of the inertia of the mesh conveyor belt 4 or the airflow of the fan, and ensuring that the fruit is always within the effective bearing range of the sponge pad 6. The inner edge of the baffle 7 is rounded to avoid scratching and damaging the blueberries. At the same time, its top is higher than the surface of the sponge pad 6 and its bottom is lower than the surface of the sponge pad 6. This does not affect the normal transport of blueberries and forms a reliable protective barrier, further improving the stability of the device during operation and the integrity of fruit transport.

[0029] The working principle of this utility model: Blueberries are placed on the sponge pad 6 of the mesh conveyor belt 4. The mesh conveyor belt 4 moves the blueberries forward. Because the sponge pad 6 is soft and has a certain elasticity, it can cushion and protect the blueberries. When the blueberries enter the enclosure 2 along the conveyor belt, multiple fans on the fan frame 10 start simultaneously, drawing in outside air from the air inlet and forming a downward airflow to perform preliminary air drying on the blueberries during the conveying process, removing some of the moisture attached to the surface of the fruit. When the blueberries move inside the cover 2, the silicone strip 14 at the bottom of the slide 8 can gently contact the surface of the blueberries, gently separating the stacked fruits and avoiding damage to the skin caused by the fruits squeezing each other. Meanwhile, the windproof cloth 16 above the slide 8 will divert and buffer the airflow generated by the fan frame 10, dispersing the originally concentrated strong airflow into multiple gentle airflows. This avoids the problem of the fruit rolling, colliding, or even falling off the sponge pad 6 due to the strong airflow directly impacting the blueberries, further improving the stability of the drying process and the protection of the fruit.
