Description

Technical Field

[0001] This utility model relates to the field of malt processing technology, and in particular to a malt root removal machine. Background Technology

[0002] Most freshly roasted malt contains 3% to 4% root sprouts. The root sprouts contain about 43% protein, have a bitter taste, are dark in color, and easily absorb water, making them unsuitable for storage. The root sprouts not only have no value in wort preparation, but also affect the taste, color, and non-biological stability of beer. Therefore, the root sprouts must be removed, and this process is called root removal.

[0003] Root removal is typically done using a malt root remover, which relies on friction between the wheat grains themselves and between the grains and a rotating drum to remove the roots. Therefore, the wheat roots must be very dry and brittle to easily detach. However, during the root removal process, the friction and compression of the malt can easily increase breakage. Furthermore, if the feed speed of the root remover is too fast, the throwing and friction of the malt will be ineffective, resulting in incomplete root removal. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a malt root removal machine to solve the problems of increased malt breakage and incomplete malt root removal caused by existing malt root removal machines.

[0005] This utility model is implemented as follows:

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figures 1-3 The diagram shows a malt root removal machine according to this invention, comprising a frame 1, a vibrating screen 2 mounted on top of the frame 1, the vibrating screen 2 being inclined, and connected to the frame 1 by multiple springs. Vibrating motors 3 are fixed to both sides of the vibrating screen 2, with the feed end of the vibrating screen 2 higher than its discharge end. An air separator (not shown) is connected to the discharge end, and a cleaning device 4 is movably connected to the top of the vibrating screen 2. The air separator is an existing, mature piece of equipment used to separate light impurities such as dust and grain husks to improve the cleaning effect.

[0026] The vibrating screen 2 has an open top and contains a screen 21 that divides it into an upper and lower space. The upper space, a rectangular cylindrical structure, is used to hold the malt to be derooted. The lower space is a conical storage compartment 22 used to store the derooted malt. A second discharge port (not shown) is located at the bottom of the storage compartment 22, through which the derooted malt is transferred from the storage compartment 22 to other containers. A first discharge port 23 is located at the lower end of the upper space, and a collection compartment 5 is located at the first discharge port 23 to collect the derooted malt roots.

[0027] like Figure 4 As shown, the cleaning device 4 includes a crossbar 41 and a cleaning brush assembly. The crossbar 41 has a U-shaped structure with its opening facing downwards. The crossbar 41 is slidably mounted on the top of the vibrating screen 2. The inner wall of the top of the crossbar 41 abuts against the top of the vibrating screen 2. There is a gap between the inner walls on both sides of the crossbar 41 and the outer walls on both sides of the vibrating screen 2, so that the crossbar 41 can move flexibly and without jamming when sliding back and forth along its length on the top of the vibrating screen 2. The top of the crossbar 41 is also provided with two handles 411 for the operator to grip when sliding the crossbar 41. Set screws 412 are screwed onto the side walls on both sides of the crossbar 41. One end of the set screw 412 abuts against or separates from the corresponding side wall of the vibrating screen 2. When it is necessary to slide the crossbar 41, one end of the set screw 412 is separated from the side wall of the vibrating screen 2, and the crossbar 41 is not fixed to the vibrating screen 2 and can slide freely on its top. When it is necessary to fix the crossbar 41, move the crossbar 41 to the higher end of the vibrating screen 2, and rotate the set screw 412 so that one end of the set screw 412 abuts against the side wall of the vibrating screen 2, so that the crossbar 41 is firmly connected to the vibrating screen 2.

[0028] The cleaning brush assembly has several vertically arranged screws 42 at its top. The top ends of the screws 42 pass through the crossbar 41 and are vertically connected to the crossbar 41. In this embodiment, there are three screws 42, which are evenly distributed along the length of the crossbar 41. Two nuts 43 are screwed to the outside of each screw 42. The bottom of one nut 43 abuts against the top of the crossbar 41, and the top of the other nut 43 abuts against the bottom of the crossbar 41, so that the cleaning brush assembly and the crossbar 41 are kept at a stable height. In use, the nuts 43 are rotated to move both nuts 43 away from the crossbar 41. Then, the relative height between the screws 42 and the crossbar 41 is adjusted. After reaching the correct height, the nuts 43 are rotated in the opposite direction to move both nuts 43 closer to the crossbar 41 and lock the screws 42 and the crossbar 41.

[0029] The cleaning brush assembly includes a brush body 44, the width of which is smaller than the internal width of the vibrating screen 2. Preferably, the width of the brush body 44 is slightly smaller than the internal width of the vibrating screen 2, so that the brush body 44 is located inside the vibrating screen 2, and there is a certain gap between the two ends of the brush body 44 and the two inner sidewalls of the vibrating screen 2. The bottom of the brush body 44 is provided with multiple bristles 45, arranged in a matrix. The bristles 45 include nylon bristles and steel wire bristles; the alternating arrangement of nylon bristles and steel wire bristles greatly improves the service life and cleaning effect of the bristles 45. When the bristles 45 wear down, the height of the screw 42 can be lowered so that the bristles 45 can brush the screen 21 below. When the vibrating screen 2 is working, the height of the screw 42 can be raised to create a certain distance between the bristles 45 and the screen 21. The screw 42 and nut 43 are designed to facilitate the operator's adjustment of the height of the bristles 45.

[0030] like Figure 2 and Figure 3 As shown, there are four springs: two first springs 6 and two second springs 7. The two first springs 6 and two second springs 7 are symmetrically arranged on both sides of the vibrating screen 2, with the length of the first spring 6 being greater than the length of the second spring 7. The first springs 6 are positioned near the feed end of the vibrating screen 2, and the second springs 7 are positioned near the discharge end of the vibrating screen 2. The bottom ends of the first springs 6 and second springs 7 are fixedly connected to the top of the frame 1, and the top ends of the first springs 6 and second springs 7 are fixedly connected to the sides of the vibrating screen 2. Through the connection of the first springs 6 and second springs 7 of different lengths, the vibrating screen 2 is inclined above the frame 1.

[0031] In use, the malt root remover of this invention places the malt to be rooted into the vibrating screen 2, starts the vibrating motor 3, and drives the vibrating screen 2 to reciprocate up and down under the action of the spring, thereby separating the malt and the root. The malt falls through the screen 21 into the storage bin 22 below, while the root is shaken out of the first discharge port 23 and falls into the collection bin 5. When it is necessary to clean the screen 21, the two set screws 412 are loosened from the vibrating screen 2, and the slide rod is pushed to slide back and forth along the length of the vibrating screen 2, so that the brush bristles 45 can clean the screen 21.

[0032] While this utility model discloses preferred embodiments to achieve the above objectives, it is not intended to limit the structural features of this utility model. Anyone skilled in the art should know that any easily conceivable variations or modifications are possible under the technical spirit of this utility model and are covered by the patent claims of this utility model.
