Abstract
Description
Technical Field
[0001] This utility model relates to the field of soybean processing technology, and in particular to a low-temperature preservation and high-efficiency peeling and kernel separation device for soybeans. Background Technology
[0002] Soybeans are an important basic raw material for the food industry, and their peeling process is a key pretreatment step in many deep processing technologies (such as protein extraction and soy food production). However, existing mainstream soybean peeling technologies have the following significant drawbacks: Traditional processes often employ hot air drying and impact or rubbing methods to remove the skins. However, high-temperature hot air can destroy heat-sensitive nutrients such as vitamins and active proteins in soybeans, and can also easily cause protein denaturation, affecting the flavor and functionality of subsequent products. At the same time, impact-based peeling can easily cause the soybean kernels to break, producing a large number of fragments and reducing the yield of high-value whole kernels.
[0003] In addition, existing separation devices are inefficient. For example, single air separation or screening is not thorough, and cross-contamination problems often occur, such as bean skin mixed with bean kernel powder and bean kernel mixed with broken skin. This makes it impossible to accurately feed materials into subsequent processes. For example, in the case of pure bean kernel demand, bean skin will make the product taste rough and dark in color. In the case of processing with skin, broken kernels will affect the stability of the process. On the other hand, it makes it impossible to classify and utilize materials of different values such as whole bean kernels and broken pieces of different sizes.
[0004] Therefore, this utility model provides a low-temperature preservation and high-efficiency soybean peeling and kernel separation device. Summary of the Invention

Whole bean kernels and larger broken pieces pass through the upper screen plate 44 and are intercepted by the lower screen plate 43. They enter the vibrating air separation mechanism 5 from the middle discharge pipe 46. Fine particles pass through the lower screen plate 43 and are discharged from the lower discharge pipe 47, thus realizing the primary separation of bean skin, kernel pieces and particles. It also includes a vibrating air separation mechanism 5, which is set behind the gravity screening mechanism 4 and is used to perform a secondary screening operation on the beans that have been screened in the first screening. The vibrating air separation mechanism 5 includes a rectangular support 3 51 and a secondary screening chamber 52 connected to the top of the support 3 51. A spring is also provided between the support 3 51 and the secondary screening chamber 52, which works with the vibrating motor 3 to make the secondary screening chamber 52 vibrate.

The broken bean kernels pass through the vibrating screen 56 and are discharged from the broken bean kernel outlet 55. At the same time, the negative pressure suction port 53 removes the residual bean skins, realizing the secondary selection of whole bean kernels, broken bean kernels and residual bean skins.
[0022] The working principle of this utility model is as follows: Soybeans are fed into the main feed inlet 21 at the top of the peeling chamber 2 and fall between two differentially rotating peeling rollers 28. Under the action of the tearing force of the peeling rollers 28, the soybean skin is peeled off from the weak parts such as the hilum of the soybean, forming a mixture of soybean skin, soybean kernel and broken pieces, which is discharged from the feed hopper 22 at the bottom of the peeling chamber to the gravity screening mechanism 4 for processing, screening and separation. During the initial screening, the vibration motor 3 at the bottom of the primary screening chamber 42 is started through the PLC control box 14, and the blower 12 is started at the same time to blow air into the feed inlet of the gravity screening mechanism 4. The mixture moves along the upper screen plate 44 with the assistance of vibration and wind. During the movement, the bean skin is discharged from the upper discharge pipe 45 and can be collected for dietary fiber extraction. Whole bean kernels and broken pieces enter the vibrating air separation mechanism 5 from the middle discharge pipe 46, and fine fragments are discharged from the lower discharge pipe 47 and used as auxiliary materials for feed or low-value products. Furthermore, the vibration motor 3 at the bottom of the secondary screening chamber 52 and the external exhaust fan connected to the negative pressure suction port 53 are started using the PLC control box 14. When the mixture of kernels and petals conveyed by the middle discharge pipe 46 enters the secondary screening chamber 52, the vibrating screen 56 vibrates. Whole kernels are discharged from the whole kernel outlet 54 along the inclined direction of the vibrating screen 56 and are used for high-end tofu, protein extraction and other processes. Broken bean petals are discharged from the broken bean petal outlet 55 along the inclined direction of the bottom of the secondary screening chamber 52 and are used for soy flour, soy milk and other processes. During the vibration, the remaining fine bean skins are sucked in by the negative pressure suction port 53 and collected by the bean skin collection box to achieve thorough purification of kernels and petals. Therefore, after completing one batch of processing, all motors and fans are shut down through the PLC control box 14, and each screen plate and screen is cleaned to avoid material residue affecting the processing accuracy of the next batch.
