Description

Technical Field

[0001] The invention belongs to the technical field of filtering devices, in particular to a beer saccharification filtering device. Background Art

[0002] Beer saccharification and filtration is to separate the lees from the wort. The filtration uses the lees to form a filter layer to filter the wort. When filtering, the existing filter tank pours the mixed solution of lees and wort into the filter tank, and stirs the mixed solution to make the lees and wort evenly distributed. Then, the mixture is allowed to stand for a period of time to allow the lees to settle on the filter plate to form a filter layer. The wort passes through the lees filter layer and the filter plate in turn to filter out clear wort. When the mixed solution is stirred, the pressure of the stirring rod on the lees can easily press the large particles in the lees into the filter groove of the filter plate, thereby causing the filter plate to be blocked, affecting the subsequent wort to pass through the filter plate and flow out of the filter tank. The blocked filter groove cannot be cleaned in time, affecting normal filtration. Therefore, we have invented a beer saccharification and filtration device to solve the above problems.

The first strip-shaped through groove 9 and the second strip-shaped through groove 10 can completely overlap or completely not overlap. By adjusting the movable plate 8 to move left and right, the overlapping part of the first strip-shaped through groove 9 and the second strip-shaped through groove 10 can be adjusted, thereby adjusting the width of the filtering through groove. The rotating tube 11 is rotatably installed in the second strip-shaped through groove 10, and the upper part of the rotating tube 11 is located in the corresponding first strip-shaped through groove 9. The rotating tube 11 can slide left and right in the corresponding first strip-shaped through groove 9. The rotating tube 11 can rotate in the first strip-shaped through groove 9 and the second strip-shaped through groove 10. One side of the outer periphery of the rotating tube 11 is in sliding contact with the corresponding side wall of the second strip-shaped through groove 10. The movable plate 8 is provided with a driving mechanism that can drive the rotating tube 11 to rotate. The present invention has a simple structure and an ingenious design. The first strip-shaped through groove 9 and the second strip-shaped through groove 10 are distributed up and down to form a filtering through groove. The width of the filtering through groove is adjusted by adjusting the overlap between the first strip-shaped through groove 9 and the second strip-shaped through groove 10 to meet the filtering requirements of different precisions, and the filtering through groove can be completely closed to avoid clogging of the filtering through groove caused by the lees being pressed into the filtering through groove during stirring. At the same time, a rotating tube 11 is provided. When the rotating tube 11 rotates, large particles of lees clogging in the filtering through groove can be cleaned out without affecting normal filtration.When using the present invention, first, by adjusting the movable plate 8 to move to the left, the first strip-shaped through-groove 9 and the second strip-shaped through-groove 10 are completely non-overlapping, and the filtering through-groove is closed, and then the mixed solution of lees and wort is injected into the tank body 1 through the feed port 2, and the sealing door 6 at the feed port 2 is closed, and the mixed solution is located on the upper side of the fixed plate 7, and then the mixed solution is stirred to make the lees and wort evenly mixed, and then the mixed mixed solution is allowed to stand for twenty minutes, so that the lees are precipitated on the upper side of the fixed plate 7 to form a filtering layer, and the wort is located above the filtering layer; and then by adjusting the movable plate 8 to move to the right, the first strip-shaped through-groove 9 and the second strip-shaped through-groove 10 are gradually overlapped to form a filtering through-groove, and the width of the filtering through-groove is gradually increased, and the filtering through-groove is opened until the width of the filtering through-groove is two millimeters.

At the same time, the rotating tube 11 rotates, and the rotating tube 11 and the bottom of the lees rub against each other. When the bottom side of the lees is transitionally compacted due to the extrusion of sedimentation, the speed of wort passing through the lees is reduced, or it cannot pass through the lees, the filtration efficiency is reduced, or it cannot be filtered. At this time, the rotating rotating tube 11 can destroy the transitionally compacted lees, and can avoid the transitional compaction of the lees sediment extrusion of the attachment on the top side of the fixed plate 7, so that the filtration can proceed normally.

The method for using the beer saccharification and filtration device according to claim 1, characterized in that: The method comprises the following steps: firstly, adjusting the movable plate (8) to move leftward so that the first strip-shaped through groove (9) and the second strip-shaped through groove (10) do not overlap at all, so that the filtering through groove is closed; then, injecting a mixed solution of lees and wort into the tank body (1) through the feed port (2), and closing the sealing door (6) at the feed port (2), so that the mixed solution is located on the upper side of the fixed plate (7); then, stirring the mixed solution so that the lees and the wort are evenly mixed; then, allowing the mixed solution to stand for twenty minutes so that the lees are precipitated on the upper side of the fixed plate (7) to form a filtering layer, and the wort is located above the filtering layer; and then, adjusting the movable plate (8) to move rightward so that the first strip-shaped through groove (9) and the second strip-shaped through groove (10) gradually overlap. A filtering groove is formed, the width of which gradually increases. When the filtering groove is opened, wort flows into the bottom of the tank body (1) through the lees filtering layer and the filtering groove, and can be discharged from the tank body (1) through the drainage hole (4). When cleaning the lees, the sealing door (6) at the discharge port (3) is opened to clean the lees. When the filtering groove is blocked, the rotating tube (11) is driven to rotate clockwise by the driving mechanism (1), and the rotating tube (11) can push the blockage upwards so that the blockage returns to the upper side of the fixed plate (7). The filtering groove can be cleaned while filtering. The lees adhering to the rotating tube (11) can be scraped off at the contact position between the movable plate (8) and the rotating tube (11), thereby cleaning the rotating tube (11).
