Description

Technical Field

[0001] This utility model relates to the field of beer production technology, specifically to a backwashable parallel basket filter device for beer production. Background Technology

[0002] Beer is a low-alcohol beverage brewed from water, barley, yeast, and hops. It typically has a refreshing taste and rich foam, and is one of the world's most popular alcoholic drinks.

[0003] Beer semi-finished fermentation liquid contains turbid substances such as yeast, large molecular proteins, polyphenols, and hop resins. In order to improve the flavor stability of the finished beer, prevent sedimentation after bottling that would affect the appearance and sales of the beer, and extend the shelf life of the beer, the beer industry usually uses centrifugation to clarify the fermentation liquid. However, existing filtration devices used in beer production have the following drawbacks:

[0004] (1) Currently, during the fermentation of craft beer, hops, tea leaves, etc. are usually added to the fermentation tank to produce beer with a distinctive style and characteristics. Hops, tea leaves, etc. are large in volume and light in weight, and are often suspended in the fermentation liquid, resulting in a large amount of large particles remaining in the fermentation liquid. This will frequently clog the centrifuge during the centrifugation process, resulting in a low centrifugation rate.

[0005] (2) Additional additives during the fermentation of craft beer can also cause large particles to remain in the sake after centrifugation, affecting bottling efficiency and the quality of the finished beer. Utility Model Content

[0006] The purpose of this invention is to provide a backwashable parallel basket filter device for beer production, so as to solve the existing problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a backwashable parallel basket filter device for beer production, comprising two filters, both filters having a feed pipe fixedly connected to their bottoms, a drain pipe fixedly connected to their bottom ends, a discharge pipe fixedly connected to their tops, and a top cover installed on the top of each filter. An exhaust pipe is fixedly connected to one side of each top cover, and a backwash pipe is fixedly connected to the other side of each top cover. A basket filter screen is fitted onto the top of the inner wall of each filter, and a bottom filter screen is installed at the bottom of the inner wall of the basket filter screen. Support rods are fixedly connected to both sides of the bottom end of the top cover, and an annular pressure frame is fixedly connected to the bottom ends of the two support rods. An inclined tube is installed at the bottom of the top cover, and a washing ball is fixedly connected to the bottom end of the inclined tube.

[0008] When using a backwashable parallel basket filter device for beer production based on this technical solution, the device is installed between the fermentation liquid and the centrifuge. By capturing large particles remaining in the fermentation liquid, it achieves a coarse filtration effect, reduces the centrifugal load on the centrifuge, and improves the centrifugal effect.

[0009] In a preferred embodiment of this invention, an annular frame is installed inside the basket filter. The annular frame supports the basket filter and prevents it from being crushed.

[0010] In a preferred embodiment of this invention, support frames are installed on both sides of the bottom of the inner wall of the filter, and the basket filter screen is placed on top of the two support frames. The support frames are provided to support the basket filter screen and improve its placement stability.

[0011] In a preferred embodiment of this invention, a sealing ring is fitted at the connection between the inner wall of the filter and the basket filter screen. This sealing ring improves the sealing performance and prevents the leakage of large particles.

[0012] In a preferred embodiment of this invention, one end of each of the two feed pipes is connected to a common feed pipe, one end of each of the two drain pipes is connected to a common drain pipe, one end of each of the two discharge pipes is connected to a common discharge pipe, one end of each of the two backwash pipes is connected to a common backwash pipe, and one end of each of the two exhaust pipes is connected to a common exhaust pipe. The common pipe connects the pipes on the two filters together.

[0013] As a preferred embodiment of this invention, sight glasses are installed at the top of the feed pipe and the bottom of the discharge pipe. These sight glasses allow for observation of the fermentation broth's condition.

[0014] In a preferred embodiment of this invention, pressure gauges are installed in the common inlet pipe, the common outlet pipe, and the exhaust pipe. The pressure gauges are used to detect the pipe pressure.

[0015] In a preferred embodiment of this invention, valves are installed in the feed pipe, drain pipe, discharge pipe, backwash pipe, and exhaust pipe. These valves are used to control the opening and closing of the pipes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This filtration device is installed between the fermentation tank and the centrifuge pipeline. The beer fermentation liquid is fed from the bottom and discharged from the top, passing through the basket filter inside the filtration chamber to intercept large particles in the fermentation liquid. This can achieve a coarse filtration effect, reduce the centrifugal load on the centrifuge, and improve the centrifugal effect. The filtration device can judge the clogging status of the filtration device by the pressure change of the pressure gauge at the material inlet and outlet of the chamber. When the basket filter is clogged, it can be backwashed through the top flushing pipeline and drained through the bottom drain valve.

[0018] 2. This filtration device can select a single filtration system or multiple filtration systems by controlling the pipeline through valves according to the amount of incoming fermentation liquid and the amount of particulate matter. The mesh size of the basket filter can be changed according to the size of the particulate matter, resulting in excellent filtration effect and avoiding the presence of large particulate matter residue in the clear wine after centrifugation, which would affect bottling efficiency and the quality of the finished wine.

A basket filter screen 13 is snapped into the top of the inner wall of the filter 1. A bottom filter screen 15 is installed at the bottom of the inner wall of the basket filter screen 13 for filtering large particles. Support rods 18 are fixedly connected to both sides of the bottom end of the top cover 2. The bottom ends of the two support rods 18 are fixedly connected to an annular pressure frame 19 for pressing the filter cylinder. An inclined tube 16 is installed at the bottom of the top cover 2. A washing ball 17 is fixedly connected to the bottom end of the inclined tube 16 for rinsing.

[0026] In use, the upper part of the cover 2 has an exhaust pipe 11 to prevent the filtration process from filling the cavity. The lower part is provided with an annular pressure frame 19 to press the basket filter screen 13. The basket filter screen 13 can be rinsed by the washing ball 17. The fermentation liquid is input from the feed pipe 3, enters the basket filter screen 13 from the bottom and the surrounding mesh, exits from the middle of the basket filter screen 13, and is discharged from the discharge pipe 7. The common discharge pipe 8 is connected to the centrifuge.

[0027] The basket filter 13 has an internal annular frame 14 to prevent deformation.

The first filtration system is checked for blockage by observing the pressure difference between the pressure gauges 24 in the feed pipe 3 and 7 in the discharge pipe. If blockage occurs during filtration, the drain valve 23 in the drain pipe 5 can be opened for drainage. If the drainage effect is not significant, feeding can be stopped and the backwash can be opened simultaneously. The washing pipe 9 valve 23 and the sewage discharge pipe 5 valve 23 backwash the basket filter screen 13 to discharge slag. The upper part of the cover 2 has an exhaust pipe 11 to prevent the filter from filling the cavity during the filtration process. The lower part is equipped with an annular pressure frame 19 to press the basket filter screen 13. The basket filter screen 13 can be washed by the washing ball 17.
