Description

Technical Field

[0001] This utility model relates to the field of beer boiling pot technology, and in particular to a boiling pot heated by direct fire. Background Technology

[0002] In craft beer wort production, there are two heating methods for the boiling pot: electric heating and steam heating. Electric heating can easily cause localized scorching due to the excessively high temperature around the resistance wire; while steam heating, because the temperature is not high enough, results in insufficient Maillard reaction during the wort boiling process, which means that the final beer lacks malt flavor.

[0003] Currently, natural gas stoves are commonly used to directly heat the bottom of the boiling pot, resulting in a very thorough Maillard reaction and a beer with a prominent malt aroma. However, this can also cause the bottom of the pot to burn, leading to a change in the beer's flavor. Therefore, it is crucial to prevent burning and ensure thorough boiling when using direct-fire heating. Thus, there is a pressing need for a boiling pot designed for direct-fire heating. Utility Model Content

[0004] The purpose of this invention is to provide a direct-fire heating boiling pot to solve the problem of scorching at the bottom of the pot, which leads to a deterioration in the taste of beer.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A direct-fire heating boiling pot includes a pot body, a motor, a rotating shaft, spiral blades, a scraper, and a wall scraper. The rotating shaft is vertically arranged and rotatably mounted in the pot body. The motor is mounted on the top of the pot body and connected to the top of the rotating shaft. The spiral blades and the scraper are both arranged on the rotating shaft, and the wall scraper is mounted on the outer end face of the scraper.

[0007] A further technical solution is that a filter screen is provided on the outside of the spiral blades.

[0008] A further technical solution is that the rotating shaft is a hollow tube, and the bottom of the rotating shaft is connected to the discharge port at the bottom of the pot body.

[0009] A further technical solution is that the wall scraper consists of multiple scrapers and is mounted on the scraper plate by screws.

[0010] A further technical solution is that the outer side of the scraper is provided with a knife-shaped protrusion, which is adapted to the inner wall of the pot body.

[0011] A further technical solution is: an arc-shaped baffle adapted to the blade-shaped protrusion is provided on the outer side of the scraper blade, and a material storage cavity is formed between the blade-shaped protrusion and the arc-shaped baffle.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] This invention proposes a direct-fire heating boiling pot. Inside the pot, a rotating shaft drives a scraper and a wall scraper to rotate, scraping away beer from the pot walls to prevent scorching. Furthermore, the rotating shaft also drives a spiral blade, which churns the beer, ensuring even heating and a full Maillard reaction. Additionally, the wall scraper has a storage chamber to temporarily store the scraped beer residue, preventing it from affecting the beer's taste. Attached Figure Description

[0024] This implementation example Figure 1 and Figure 2 As shown, a direct-fire heating boiling pot includes a pot body 1, a motor 2, a rotating shaft 3, a spiral blade 4, a scraper 5, and a wall scraper 6. The rotating shaft 3 is vertically arranged and rotatably installed inside the pot body 1. The motor 2 is installed on the top of the pot body 1 and connected to the top of the rotating shaft 3. The spiral blade 4 and the scraper 5 are both arranged on the rotating shaft 3. The wall scraper 6 is installed on the outer end face of the scraper 5.

[0025] When the natural gas stove heats the bottom of the pot 1, the motor 2 will also rotate the shaft 3, and the spiral blade 4, scraper 5 and wall scraper 6 will also rotate together to start the beer heating and boiling process. During this time, the wall scraper 6 can scrape the beer off the inner wall of the pot, especially near the bottom, to prevent the pot wall from being heated and causing it to burn. In addition, the spiral blade 4 will also churn the beer in the pot to ensure that the beer is heated evenly and that the Maillard reaction is complete, thus ensuring the taste of the beer.

[0026] Preferably, a filter screen 7 is provided outside the spiral blade 4.

[0027] The filter screen 7 will block the paste scraped off the inner wall of the pot by the scraper 6.

[0028] Preferably, the rotating shaft 3 is a hollow tube, and the bottom of the rotating shaft 3 is connected to the discharge port at the bottom of the pot body 1.

[0029] With the filter screen 7 blocking the paste-like substances, the pure beer will flow out from the discharge port at the bottom of the pot body 1 through the rotating shaft 3.

[0030] Preferably, the wall scraper 6 consists of multiple scrapers and is mounted on the scraper 5 by screws.

[0031] The wall scraper consists of multiple scrapers, which serves two purposes: first, to facilitate installation and disassembly; and second, to make it easy to operate and greatly reduce costs when the scrapers may be damaged and need to be replaced after a period of operation. Example

[0032] Based on the previous embodiment, this embodiment shows that the outer side of the scraper blade 6 is provided with a blade-shaped protrusion 8, which is adapted to the inner wall of the pot body 1. The outer side of the scraper blade 6 is provided with an arc-shaped baffle 9 adapted to the blade-shaped protrusion 8, and a material storage cavity 10 is formed between the blade-shaped protrusion 8 and the arc-shaped baffle 9.

[0033] When the scraper blade 6 rotates, the blade-shaped protrusion 8 will press against the inner wall of the pot body 1 to scrape the paste-like material adhering to the inner wall of the pot body 1. The scraped-off material will be blocked by the arc-shaped baffle 9. The scraper blade has a material storage cavity, which can temporarily store the scraped-off material (beer paste) to prevent the material from having an adverse effect on the taste of the beer.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
