Technical Field

[0001] The utility model belongs to the technical field of wort filtration, and particularly relates to a beer wort filtration device. Background Art

[0002] Wort is the main raw material for beer production. During the saccharification process of wort, it is necessary to filter the wort to obtain clear wort.

[0003] For wort filtration devices, in the prior art, after retrieval, a utility model patent with the Chinese patent publication number CN204981829U discloses a beer wort filtration device. As Figure 1 shown, it mainly includes a filtration tank a, which is divided into a filtration chamber b on the upper side and a boiling pan c on the lower side. A filter screen d is provided at the bottom of the filtration chamber b, a sewage outlet e is provided at the bottom of the boiling pan c, a feed inlet f is provided at the upper part of the boiling pan c, and the filtered wort in the filtration chamber b directly enters the boiling pan c for boiling.

[0004] In the prior art, for beer wort filtration devices with similar technical solutions above, it is found that there are areas for improvement during actual implementation: when the wort starts to be filtered, the formed filtration layer is not yet stable enough, resulting in the initially filtered wort being relatively turbid (containing starch paste). This part of the turbid wort directly flows into the boiling pan for the next process, which easily affects the taste of the beer. Summary of the Utility Model

[0005] In view of the deficiencies and defects existing in the prior art, the purpose of the present utility model is to provide a beer wort filtration device, which solves the problem that the turbid wort that appears when the wort is initially filtered in the existing wort filtration device directly flows into the boiling pan for the next process, which easily affects the taste of the beer.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions: a beer wort filtration device includes a filtration tank and a boiling pan. The upper part of the filtration tank is provided with a feed inlet, and further includes a three-way liquid outlet pipe. A conical transition hopper is provided at the bottom of the filtration tank. A filter plate is provided above the conical filtration hopper inside the filtration tank. The bottom of the conical transition hopper is provided with a liquid outlet. A reflux port is provided on one side of the top of the filtration tank. One end of the three-way liquid outlet pipe is communicated with the liquid outlet, one end is communicated with the reflux port through a reflux pipe, and the other end is communicated with the boiling pan through a flow pipe. A stirring member is provided inside the filtration tank. A circle of spray heads is provided near the upper end inside the filtration tank. The spray heads are connected to a water tank. Valves are provided at one end of the reflux pipe and the flow pipe close to the three-way liquid outlet pipe. A reflux pump is provided on the reflux pipe.

[0007] As a further improvement of the present utility model, a heat insulation layer is provided outside the filtration tank.

[0008] As a further improvement of the present utility model, the stirring member includes a stirring shaft and stirring blades. The stirring blades are vertically arranged on the stirring shaft, and the bottom of the stirring blades is serrated. The top of the stirring shaft extends out of the filter tank and is connected to a motor.

[0009] As a further improvement of the present utility model, a transparent observation cylinder is connected to the middle of the reflux pipe.

[0010] As a further improvement of the present utility model, a flow-through pump is provided on the flow-through pipe.

[0011] As a further improvement of the present utility model, an annular support slot is arranged in the filter tank at the position where the filter plate is arranged, and the filter plate is snap-fitted in the support slot.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. By providing a three-way liquid outlet pipe, a reflux pipe, a reflux port and a flow-through pipe, one end of the three-way liquid outlet pipe is connected to the liquid outlet, one end is communicated with the reflux port through the reflux pipe, and the other end is communicated with the boiling pot through the flow-through pipe. Then, within an initial period of filtration time, the wort flowing out of the filter tank first flows into the filter tank again through the reflux pipe for further filtration. After the flowing wort becomes clear, the reflux pipe is closed, the flow-through pipe is opened, and then the wort is diverted into the boiling pot for subsequent processes, avoiding the problem of affecting the taste of beer caused by the directly flowing of the initially filtered turbid wort from the filter tank into the boiling pot.

[0014] In addition, by providing a conical transition hopper at the bottom of the filter tank, it is convenient for the downward diversion of the wort. And a ring of spray heads is arranged near the upper end in the filter tank. When the filtration is approaching the end, the spray heads are opened, and the spray heads inject water into the filter tank to wash the wort in the spent grains to complete the mash lautering.

[0015] 2. By providing a heat preservation layer outside the filter tank, it is convenient to keep the filtrate warm, so that the filtration temperature in the filter tank is maintained within a suitable temperature range (about 78 degrees Celsius).

[0016] 3. By providing a stirring member in the filter tank, the wort and the spent grains can be stirred, so that the spent grains are flattened on the filter plate to form a stable filtration layer, and the wort in the spent grains is fully filtered out.

[0017] 4. By connecting a transparent observation cylinder to the middle of the reflux pipe, it is convenient to observe the clarity of the refluxing wort.

[0018] 5. By providing a support slot and arranging the filter plate on the support slot, the filter plate can be disassembled for convenient cleaning. Description of the Drawings

[0024] For the convenience of description, a coordinate system is now defined as Figure 2 shown, and the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0025] An embodiment of the present utility model discloses a beer wort filtration device. Referring to Figure 2 , a beer wort filtration device includes a filter tank 1, a boiling pot 11, and a three-way liquid outlet pipe 4. The outside of the filter tank 1 is provided with a thermal insulation layer 15 to facilitate heat preservation of the filtrate, so that the filtration temperature in the filter tank 1 is maintained within a suitable temperature range (about 78 degrees Celsius). The upper part of the filter tank 1 is provided with a feed inlet 3, and the bottom of the filter tank 1 is provided with a conical transition hopper 5 to facilitate the downward flow of the wort. Above the conical filter hopper in the filter tank 1, a filter plate 6 is provided. The filter plate 6 is detachably connected to the filter tank 1 by bolts. For example, an annular support slot for supporting the filter plate 6 can be provided in the filter tank 1, and the filter plate 6 can be directly snap-fitted on the support slot, so that the filter plate 6 can be detached for easy cleaning.

[0026] In addition, a liquid outlet 7 is provided at the bottom of the conical transition hopper 5, and a reflux port 8 is provided on one side of the top of the filtration tank 1. One end of the tee liquid outlet pipe 4 is communicated with the liquid outlet 7, one end is communicated with the reflux port 8 through a reflux pipe 9, and the other end is communicated with a boiling pan 11 through a flow pipe 10. A ring of spray heads 12 is provided near the upper end inside the filtration tank 1, and the spray heads 12 are connected to a water tank (not shown in the drawings). When the filtration is nearly finished, the spray heads 12 are opened, and the spray heads 12 inject water into the filtration tank 1 to wash the wort in the spent grains, completing the mash lautering. Valves 13 are provided at one ends of the reflux pipe 9 and the flow pipe 10 close to the tee liquid outlet pipe 4. A reflux pump 14 is provided on the reflux pipe 9, and a flow pump 17 is provided on the flow pipe 10. The opening and closing of the valves 13 can be controlled by a control system. For example, the valve 13 on the reflux pipe 9 is opened at the initial stage of filtration and closed after a certain time of reflux is set.

[0027] In addition, a transparent observation cylinder 16 is connected to the middle of the reflux pipe 9, which is convenient for observing the clarity of the refluxed wort.

[0028] In addition, a stirring member 2 is provided inside the filtration tank 1. Specifically, the stirring member 2 includes a stirring shaft 21 and stirring blades 22. The stirring blades 22 are vertically arranged on the stirring shaft 21, and the bottom of the stirring blades 22 is serrated. The top of the stirring shaft 21 extends out of the filtration tank 1 and is connected to a motor 23; thereby, the wort and the spent grains can be stirred, so that the spent grains are flattened on the filter plate 6 to form a stable filtration layer, and the wort in the spent grains is fully filtered out.

[0029] The implementation process of the present utility model is as follows: Close the valves 13 on the reflux pipe 9 and the flow pipe 10, add filtrate into the filtration tank 1, and turn on the motor 23. The motor 23 stirs the filtrate through the stirring shaft 21 and the stirring blades 22. After standing for a certain time, the spent grains sink to the bottom to form a filtration layer. Open the valve 13 on the reflux pipe 9 and the reflux pump 14, and the filtered wort starts to reflux into the filtration tank 1 from the reflux pipe 9 for re-filtration. After a certain time, the valve 13 on the reflux pipe 9 is closed, and the valve 13 on the flow pipe 10 is opened. The clear wort flows into the boiling pan 11 through the flow pipe 10. At the end of filtration, the spray heads 12 are opened to spray water into the filtration tank 1 to complete the washing of the spent grains. After a certain time, the spray heads 12 are closed to complete the entire filtration process.

[0030] The implementation effect of the present utility model is as follows: By providing a three-way liquid outlet pipe 4, a reflux pipe 9, a reflux port 8 and a flow-through pipe 10, one end of the three-way liquid outlet pipe 4 is connected to the liquid outlet 7, one end is communicated with the reflux port 8 through the reflux pipe 9, and the other end is communicated with the boiling pot 11 through the flow-through pipe 10. During the initial filtration period, the wort flowing out from the filtration tank 1 first flows into the filtration tank 1 again through the reflux pipe 9 for re-filtration. After the flowing wort becomes clear, the reflux pipe 9 is closed, the flow-through pipe 10 is opened, and then the wort is diverted into the boiling pot 11 for subsequent processes, avoiding the problem that the turbid wort initially filtered from the filtration tank 1 directly flows into the boiling pot 11, which affects the taste of the beer.
