[0002] Apple polyphenols are a class of natural compounds with various physiological activities widely present in fruits, and have important applications in industries such as food, medicine, and cosmetics. During the extraction process of apple polyphenols, whether it is for the fruit raw material itself, or in the intermediate extraction links and the separation and purification stage of the final extract, screening operations are often required to ensure the extraction efficiency and product quality. Although traditional vibration screening devices can achieve the basic function of material screening, there are some deficiencies when applied to apple polyphenol extraction. When replacing filter holes of different sizes in existing apple polyphenol screening devices, it often requires manual disassembly of the filter screen, and it is impossible to quickly and automatically adjust the screen to a suitable mesh gap according to different sizes of apple polyphenol molecules and the vibration frequency, and there is a lack of protective measures, making it difficult to meet the diverse filtering requirements of different extraction stages, resulting in damage to its active ingredients and affecting the screening continuity.

The number of the first motor 41, the stirring shaft 42, the stirring blades 43 and the buffer inclined plate 44 is four. The buffer inclined plate 44 is fixed inside the primary screening frame 32; Specifically, when the apple polyphenol compound is put into the four feeding hoppers 31, first, it is preliminarily screened by the first filter screen 33 and the second filter screen 34 inside the primary screening frame 32, and then the first motor 41 in the stirring structure 4 drives the stirring shaft 42 and the four stirring blades 43 to act simultaneously, which is convenient for preliminarily filtering and stirring the preliminarily screened apple polyphenol compound.

[0023] Example 2. The adjustment structure 8 is arranged behind the discharge port 7. The sealing sliding frame 5 is slidably connected to the inside of the primary screening frame 32. The pore size of the first filter screen 33 is larger than that of the second filter screen 34, and the pore size of the third filter screen 85 is larger than that of the fourth filter screen 88. Specifically, by arranging the adjustment structure 8 behind the discharge port 7, when it is necessary to automatically adjust the pore sizes of the third filter screen 85 and the fourth filter screen 88, only need to start the third motor 81 to drive the driving gear 82 and the driven gear 83 to move. The two linkage rods one 84 and the two linkage rods two 87 are linked to drive the two fourth filter screens 88 and the third filter screen 85 to overlap, which is convenient for automatically adjusting to a suitable mesh pore size. Through the arrangement of the sealing sliding frame 5, for some easily oxidized apple polyphenols, their active ingredients will not be damaged under the conditions of long-term exposure to air and heat accumulation caused by vibration.

[0024] Example 3. The heat dissipation scraper structure 10 includes a transmission frame 101, a fourth motor 102, a heat pump fan 103, a pulley 104 and a transmission belt 106. The two fourth motors 102 are fixed inside the transmission frame 101. The transmission belt 106 is transmitted on the output end of the fourth motor 102. The pulley 104 is transmitted on the transmission belt 106. A transmission shaft 105 is fixed between the two pulleys 104. A cleaning roller 107 is arranged on the transmission shaft 105. Side scrapers 108 are transmitted on both sides of the transmission shaft 105. Two grooves are opened behind the sealing sliding frame 5. A hydraulic rod 109 is fixed inside the grooves. The heat pump fan 103 is arranged at the bottom of the transmission frame 101. Air blowing pipes 110 are fixed on both sides of the bottom of the heat pump fan 103. A temperature sensor 11 and a shock sensor 12 are arranged inside the primary screening frame 32. Specifically, when the temperature sensor 11 detects a high temperature, start the heat pump fan 103, and the air blows into the inside of the transmission frame 101 from the air blowing pipes 110 arranged at the bottom to cool the inside of the transmission frame 101. When the temperature sensor 11 detects a low internal temperature, start the heat pump fan 103 to perform the internal temperature increase operation.

[0025] Example 4. Sliding grooves are opened on both side walls of the sealing sliding frame 5. The sliding plate 67 is slidably connected to the inside of the sliding grooves. The number of the two buffer inclined plates 44 is two and they are symmetrically arranged. Universal wheels are fixed at the four corners of the bottom of the main body frame 2. Transparent windows are arranged on the front surfaces of the sealing sliding frame 5 and the main body frame 2. Specifically, when the sliding plate 67 slides, the second motor 61 drives the wheel shaft 62 and the eccentric wheel 63 to rotate, driving the sliding plate 67 to slide on the sliding rod 69. At this time, the limiting ball 65 slides inside the limiting ring 66. Restricted by the limiting ball 65 of the limiting ring 66, the shock structure 6 oscillates the apple polyphenol molecules inside the primary screening frame 32, and the oscillation effect is good. And by arranging two shock structures 6 to slide on the sliding rod 69, the sliding is more stable.

[0026] Embodiment 5: Temperature sensors 11 are provided at the four corners inside the sealed sliding frame 5, and a controller is fixed on the outer wall of the right side of the main frame 2. The controller is electrically connected to the temperature sensors 11, the shock sensor 12, the first motor 41, the second motor 61, the third motor 81, the fourth motor 102, the first telescopic rod 86, and the hydraulic rod 109 respectively; Specifically, the temperature sensors 11 are provided to detect the temperature inside the screening equipment main body 1 in real time. The controller is connected to each device, facilitating the real-time control of each device to ensure the normal operation of each device.

[0027] Specifically, the second motor 61 in the two shock structures 6 drives the wheel shaft 62 to rotate simultaneously, driving the rotating rod 64 and the limiting ball 65 on the eccentric wheel 63 to slide inside the fixed plate 661, promoting the entire primary screening structure 3 to shake the apple polyphenol molecules inside the primary screening frame 32. By setting the aperture of the first filter screen 33 to be larger than that of the second filter screen 34, it is convenient to filter and screen the apple polyphenol molecules for the first time while shaking. Through the setting of the second telescopic rod 14 and the telescopic spring 15, it is convenient to drive the third filter screen 85 and the fourth filter screen 88 to vibrate while vibrating the first filter screen 33 and the second filter screen 34. After the vibration is completed, the shock sensor 12 analyzes the vibration frequency to obtain the current vibration frequency, and starts the third motor 81 in the adjustment structure 8 to drive the driving gear 82 and the driven gear 83 to rotate. The two first linkage rods 84 and the second linkage rod 87 are linked, facilitating the coincidence of the third filter screen 85 and the fourth filter screen 88, thereby changing the gap between the third filter screen 85 and the fourth filter screen 88, realizing different overall aperture sizes as a whole, achieving the effect of filtering according to requirements, and thus realizing the effect of automatically adjusting to a suitable mesh gap according to the sizes of different apple polyphenol molecules and the vibration frequency.

[0028] Specifically, through the setting of the first filter screen 33, the second filter screen 34, the third filter screen 85, and the fourth filter screen 88, during the preliminary filtration of the first filter screen 33 and the second filter screen 34, the first motor 41 is started to drive the stirring shaft 42 and the stirring blades 43 to stir the apple polyphenol molecules. At the same time, the shock structure 6 performs shock filtration on the entire primary screening structure 3. When it enters the third filter screen 85 and the fourth filter screen 88, superimposed filtration and separate filtration can be realized as needed, and the screening continuity is good.

[0029] Working principle: First, the screening equipment body 1 is moved to the position where it needs to be used through the four universal wheels at the bottom, and the apple polyphenol molecules enter the interior of the screening equipment body 1 through the four hoppers 31. The apple polyphenol molecules are preliminarily filtered through the first filter screen 33 and the second filter screen 34, and enter the buffer inclined plate 44 for buffering. At the same time, the second motor 61 in the oscillation structure 6 drives the wheel shaft 62 to rotate, and drives the rotating rod 64 on the eccentric wheel 63 and the limiting ball 65 to slide inside the fixed plate 661. The entire primary screening structure 3 oscillates and shakes the apple polyphenol molecules inside the primary screening frame 32. The telescopic rod 14 and the telescopic spring 15 are simultaneously extended and retracted, and the third filter screen 85 and the fourth filter screen 88 are driven to vibrate while the first filter screen 33 and the second filter screen 34 vibrate. During this period, the staff can observe in real time through the transparent window in front of the main frame 2. When the internal temperature is too high or too low, the temperature sensor 11 senses it and sends a command to the controller to start the heat pump fan 103 and the blow pipe 110 to vibrate the interior of the main frame 2 Blowing air to achieve cooling or heating operation. When it is necessary to clean the inner wall of the sealing sliding frame 5, the fourth motor 102 in the heat dissipation scraper structure 10 is started to drive the pulley 104 to rotate, and the transmission belt 106 drives the cleaning roller 107 and the two side scrapers 108 to swing horizontally and vertically. When the two hydraulic rods 109 rise, the cleaning roller 107 cleans the inner wall of the sealing sliding frame 5, and cooperates with the two side scrapers 108 to achieve comprehensive cleaning of the interior. The apple polyphenol molecules enter the discharge port 7. The apertures of the two third filter screens 85 are consistent. When the oscillation sensor 12 detects that equivalent apertures of different sizes need to be formed, the third motor 81 is started to drive the driving gear 82 and the driven gear 83 to transmit, and the two linkage rods 1 84 and the linkage rod 2 87 are linked to overlap or separate the third filter screen 85 and the fourth filter screen 88, thereby changing the gap between the third filter screen 85 and the fourth filter screen 88. Subsequently, the apple polyphenol molecules are filtered from the third filter screen 85 and the fourth filter screen 88. At this point, the entire workflow ends.
