Technical Field
[0001] The utility model belongs to the technical field of food processing, and in particular relates to a quinoa particle screening device. Background Art
[0002] Quinoa is a high-nutrient, low-sugar, high-altitude crop.
[0003] In order to facilitate the uniformity and size of quinoa during shelling, a screening device is often set up for screening before processing. The existing particle screening devices mostly use a vibration device to make the screen plate shake, so that the particles above fall, and screen. In order to prevent the middle and high-level particles from falling, except for the last layer, the screen plates in other places are mostly in an active sealing state, resulting in more and more particles above the middle and high-level screen plates as the working time goes by, causing the shaking effect to become worse and worse, and the particles entering later cannot pass through the obstruction of the particles below and enter the lower layer for screening, which ultimately leads to the inability to perform effective particle screening.
[0004] Therefore, how to provide a quinoa particle screening device is a problem that those skilled in the art urgently need to solve. Utility Model Content
[0005] The utility model aims to provide a quinoa particle screening device, aiming to solve the problems mentioned in the background technology.
[0006] The utility model is implemented as follows: a quinoa particle screening device comprises:
[0007] Screening boxes;
