Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a device for removing impurities from watermelon seed kernels. Background Technology

[0002] Watermelon seeds are the shelled part of watermelon seeds. They are sweet and neutral in nature. Watermelon seeds are rich in protein, fat, vitamins and minerals, and have the effects of moisturizing the intestines and relieving constipation, clearing the lungs and resolving phlegm, and supplementing nutrition.

[0003] Impurity removal devices can effectively remove impurities from watermelon seed kernels, such as empty shells, broken shells, dust, and pebbles, thereby improving the purity and quality of the watermelon seed kernels. Therefore, impurity removal devices are necessary. However, the design of traditional impurity removal devices may focus more on removing larger impurities, such as empty shells and broken shells, while lacking an effective extraction mechanism for tiny dust impurities. This may lead to the accumulation of dust impurities inside the device, making it difficult to remove them effectively. Dust may contain harmful substances such as microorganisms and bacteria. If it cannot be effectively extracted, it may pose a threat to the food safety of watermelon seed kernels. Long-term consumption of food containing dust impurities may have adverse effects on human health. The main design purpose of watermelon seed kernel impurity removal devices is to remove impurities, rather than to finely sieve the watermelon seed kernels. Therefore, the design of the device may focus more on the effect of impurity removal than on the realization of sieving function. If the sieving effect is not good, the watermelon seed kernels may still contain impurities, such as immature watermelon seeds, broken watermelon rinds, watermelon pulp, or other foreign substances. These impurities will reduce the overall quality of the product and affect consumers' willingness to buy and their eating experience. Utility Model Content

[0028] Working principle: In use, watermelon seed kernels are first poured into the feeding frame 18. At this time, the second motor 15 is turned on, and the rotation of the second motor 15 drives the conveyor shaft 16 to rotate. The rotation of the conveyor shaft 16 drives the watermelon seed kernels to be conveyed through the device body 1 and into the cylinder 81. At this time, the first motor 10 is turned on, and the rotation of the first motor 10 drives the rotating rod 11 to rotate. The rotation of the rotating rod 11 drives the mounting plate 83 to rotate. The rotation of the mounting plate 83 drives the rotating roller 84 to rotate. When the cylinder 81 rotates, the watermelon seed kernels will bounce in the air to remove impurities. The watermelon seed kernels that fall directly out of the cylinder 81 have already completed the first layer of impurity removal through squeezing and collision during the conveying process. The impurities and dust in the watermelon seeds are removed by the collision of the rotating roller 84. At this time, the blower 6 is turned on, which creates a negative pressure in the conversion box 4. The air is connected to the main body 1 through the connecting pipe 3, and the dust and impurities are drawn into the conversion box 4. The regulating valve is opened to discharge them. The watermelon seeds in the cylinder 81 that are within the diameter of the sieve hole 82 will fall into the hopper 2. The sealing plate 25 is opened to remove them. If there are no watermelon seeds that are within the size of the sieve hole 82, the regulating plate 23 is opened, and then the fixing plate 24 is opened to remove the remaining watermelon seeds in the cylinder 81. This achieves the effect of removing impurities and screening at the same time. In addition, the watermelon seeds that are within the size of the sieve hole 82 have already been removed by collision and compression during the conveying process of the conveyor shaft 16.
