Description

Technical Field

[0001] This utility model relates to the field of brewing, and in particular to a device for crushing and removing impurities from grain raw materials used in brewing. Background Technology

[0002] Crushing and removing impurities from the five grains used in brewing is a crucial step in the brewing process, aiming to improve the utilization rate of raw materials and the quality of the liquor. The five grains are composed of various grains such as sorghum, corn, wheat, rice, and barley. Each grain has different physical properties and composition. Therefore, they need to undergo crushing and impurity removal processes before brewing. The crushing process uses specialized equipment to grind the raw materials into particles of a certain size to increase their contact area with water and yeast, thereby accelerating the saccharification process. The degree of crushing directly affects the fermentation efficiency and taste of the liquor. The particle size of the five grains should be moderate and not too fine to prevent affecting the activity of yeast or causing incomplete saccharification.

[0003] The impurity removal process is to remove impurities from the raw materials. Impurities not only affect the quality of brewing but may also damage production equipment. Through equipment such as vibrating screens, magnetic separators, and airflow separators, these impurities can be effectively removed, ensuring that the raw materials entering the brewing process are clean and pure. Raw materials that have been crushed and impurity removed are more uniform, ensuring the smooth progress of subsequent processes such as saccharification and fermentation, thereby improving the yield and quality of the wine. In addition, proper crushing and impurity removal can also reduce off-flavors in the wine, enhance its taste, and make the final product of higher quality.

[0004] When crushing grain raw materials, the filter screen inside the equipment needs to be replaced according to the size of the grain particles to ensure that the crushed grain particles are of consistent size. However, in traditional raw material crushing devices, the filter screen is replaced by turning a manual bolt to open the cover plate. Turning the manual bolt requires a lot of force, which is time-consuming, labor-intensive, and inefficient. Therefore, a grain raw material crushing and impurity removal device for brewing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grain crushing and impurity removal device for brewing, which aims to improve the problem that in traditional raw material crushing devices, changing the filter screen is done by turning a manual bolt to open the cover plate.

[0021] Working Principle: When using the crusher 1 to crush grains, first adjust the mesh size of the filter screen 3 according to the size of the grain particles to be crushed. By pulling the handle 10, the pull rod 7 extends out of the housing 6. At the same time, the sliding plate 8 squeezes the spring 9 and pulls the handle 10 outward, disengaging it from the hook 5. At this time, the cover plate 4 is unlocked. Open the cover plate 4, then remove the original filter screen 3 and replace it with a suitable filter screen 3. Close the cover plate 4 again, then pull the pull rod 7 back and release the handle 10. At this time, the spring 9 will immediately push the sliding plate 8, driving the pull rod 7 to pull the hook 5, so that the cover plate 4 is tightly attached to the front of the crusher 1 and remains stable. At this time, the crusher 1 can be controlled to start working, and the internal crushing system starts to rotate. Then, the grains are fed into the crusher 1 through the feed inlet 2. After entering the feed inlet 2, the grains will fall into the crusher 1 through the central hole. At this time, the motor 14 drives the gear 13 to rotate. Through the meshing of the two, the crushing process is completed. When the magnetic roller 11 rotates, its suction force will remove metal impurities from the grains, thus preventing impurities from affecting the quality of the raw materials. When the magnetic roller 11 rotates, the impurities will be scraped off by the scraper 12 and fall into the collection frame 16. The grains falling into the crusher 1 are crushed and filtered by the filter screen 3. Grains of qualified size are discharged from the outlet until the grains are completely crushed. Then, the collection frame 16 is removed to remove the impurities. By pulling the collection frame 16 forcefully, it is removed from the sleeve frame 15 and detached from the ball bearing 20. After removing the impurities, the collection frame 16 is slid back into the sleeve frame 15. Initially, the collection frame 16 will squeeze the ball bearing 20, causing the sliding frame 19 to compress the second spring 18. When the collection frame 16 slides to the bottom, the second spring 18 will immediately push the sliding frame 19 to reset the ball bearing 20, causing the ball bearing 20 to lock into the back of the collection frame 16. Then, it can be used again. The operation is convenient and labor-saving.
