Technical Field

[0001] This utility model relates to the technical field of boiling equipment, and in particular to a material boiling pot. Background Technology

[0002] Boiling the wort is a crucial step in the beer brewing process. Boiling sterilizes the wort, stops enzyme activity, evaporates water, and concentrates the wort. It occurs after saccharification (converting starch in malt into sugar) and before fermentation.

[0003] For example, Chinese utility model patent CN223201813U discloses a boiling pot for beer production, including a pot body for containing wort and heating and boiling the wort, and a heat exchanger. Before entering the pot body, the low-temperature wort exchanges heat with the high-temperature wort flowing out of the pot body in the heat exchanger. This makes the entire heating process more uniform, avoids localized overheating, improves beer quality, and fully recovers and utilizes heat, saving energy and reducing the additional energy required to cool the high-temperature wort.

[0004] However, the above-mentioned device still has the following drawbacks: water needs to be evaporated during the wort boiling process, and the existing boiling pot has a limited evaporation area, which is not conducive to the concentration of wort, and the uniformity of heating of wort during the boiling process needs to be further improved.

[0017] As described in the background art, a boiling pot for beer production is used. During the boiling process of wort, water needs to be evaporated. Existing boiling pots have limited evaporation area, which is not conducive to the concentration of wort. Furthermore, the uniformity of heating of wort during the boiling process needs to be further improved.

[0018] To solve this technical problem, this utility model provides a material boiling pot, which is applied to the boiling treatment of wort.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Example 1 Please refer to Figures 1-4A material boiling pot includes a heating pot body 1 and a heating assembly for heating and boiling wort inside the heating pot body 1; it also includes a hollow shaft 2 installed in the upper part of the heating pot body 1, a spray plate 3 installed at the bottom of the hollow shaft 2, a connecting pipe 4, and a circulation pump 5. The input end of the circulation pump 5 extends into the bottom of the heating pot body 1. One end of the connecting pipe 4 is connected to the input end of the circulation pump 5, and the other end of the connecting pipe 4 is connected to the upper part of the hollow shaft 2 and communicates with the interior of the hollow shaft 2. The spray plate 3 has a liquid distribution chamber 6, and multiple liquid distribution pipes 7 connected to the interior of the liquid distribution chamber 6 are installed on the spray plate 3. The multiple liquid distribution pipes 7 are evenly distributed around the circumference of the spray plate 3; furthermore, the spray plate... The liquid level 3 is at least 40cm higher than the highest liquid level inside the heating pot 1 to ensure that the wort sprayed from the liquid distribution pipe 7 has sufficient falling height; multiple liquid distribution pipes 7 are arranged radially along the spray plate 3 so that the wort sprayed from each liquid distribution pipe 7 forms an umbrella-shaped surface; the central axes of the heating pot 1, the hollow shaft 2, and the spray plate 3 coincide; the heating components can be electric heating elements, gas heating elements, or steam heating elements; the bottom of the heating pot 1 is equipped with a drain pipe, and a drain valve is installed on the drain pipe. Necessary switching valves and other valves are installed on the connecting pipe 4 and the input end of the circulating pump 5; the heating pot 1 is equipped with a maintenance cover so that operators can perform maintenance and repair on the inside of the heating pot 1.

[0022] For details, please refer to Figures 3-4 The hollow shaft 2 is rotatably mounted on the heating pot body 1. The bottom of the spray plate 3 is fixedly mounted with a stirring shaft 8, and a stirring paddle 9 is mounted on the stirring shaft 8. The output end of the liquid distribution pipe 7 is equipped with a nozzle 10. The central axis of the nozzle 10 forms an angle of 30-60° with the corresponding radial line on the spray plate 3. The outlet end of the nozzle 10 faces the outside of the spray plate 3. The outlet ends of multiple nozzles 10 are all inclined clockwise or counterclockwise around the spray plate 3. The hollow shaft 2 is rotatably and sealed to the connecting pipe 4 through a rotating sealing joint, etc.

[0023] For details, please refer to Figures 3-4 The outer wall of the heating pot body 1 is covered with a heat insulation layer 19; furthermore, the heat insulation layer 19 can be a vacuum heat insulation layer or an equidistant heat insulation structure with heat insulation effect such as heat insulation cotton.

[0024] The material boiling pot provided in this embodiment, after the wort is sprayed from the nozzle 10, exerts a tangential force on the spray plate 3, causing the spray plate 3 to rotate. During the rotation of the spray plate 3, the stirring shaft 8 and the stirring paddle 9 rotate. The stirring paddle 9 agitates the wort solution at the bottom of the heating pot 1. Under the agitation, the uniformity of contact between the wort and the heating components is further improved, thereby improving the uniformity of heating of the wort. Moreover, the agitation facilitates the evaporation of water in the wort, improving the concentration efficiency of the wort. The heat insulation layer 19 can reduce the heat loss from the heating pot 1, making it more energy-efficient.

[0025] Example 2 The material boiling pot provided in Example 1 has been further optimized. For details, please refer to [link / reference needed]. Figures 3-5 Multiple anti-splash plates 11 are fixedly installed in the upper part of the heating pot body 1. The multiple anti-splash plates 11 are evenly distributed around the inner wall of the heating pot body 1. The anti-splash plates 11 are arranged corresponding to the nozzles 10. The anti-splash plates 11 are used to reflect the water flow at the nozzles 10 and provide reverse thrust for the rotation of the spray plate 3.

[0026] For details, please refer to Figures 2-5 The heating assembly includes a spiral heating tube 20, an air inlet pipe 21 connected to the air inlet end of the spiral heating tube 20, and an air outlet pipe 22 connected to the air outlet end of the spiral heating tube 20. The spiral heating tube 20 is fixedly installed on the inner wall of the heating pot body 1.

[0027] Specifically, both the heating pot body 1 and the anti-splash plate 11 are made of stainless steel.

[0028] For details, please refer to Figures 3-4 The anti-splash plate 11 extends downwards to below the liquid level inside the heating pot 1.

[0029] In the material boiling pot provided in this embodiment, pressurized wort sprayed from each nozzle 10 is sprayed onto the anti-splash plate 11. Under the reverse thrust of the anti-splash plate 11, the reverse thrust generates a greater rotational torque on the spray plate 3, thereby increasing the rotational speed of the spray plate 3 and further improving the stirring effect of the agitator 9 on the wort. The anti-splash plate 11 can further disperse the wort in contact with the anti-splash plate 11, further increasing the evaporation area of ​​the wort and improving the concentration effect of the wort. External high-temperature steam can be injected into the spiral heating tube 20 through the air inlet pipe 21, and the spiral heating tube 20 heats the heating pot body 1 and the wort inside the heating pot body 1. The anti-splash plate 11 can heat the heating pot body Heat from point 1 is transferred to the upper and middle parts of the heating pot body 1 to improve the temperature uniformity within the heating pot body 1. The stainless steel material is not easily corroded, meets the hygiene requirements for food processing, and has good thermal conductivity. It can transfer the heat from the heating element to the entire heating pot body 1 through the heating pot body 1 and the anti-splash plate 11, further ensuring the uniform heating of the wort. The anti-splash plate 11 extends to the bottom of the heating pot body 1, and heat is transferred to the wort through the anti-splash plate 11. Some of the wort sprayed onto the anti-splash plate 11 flows down along the anti-splash plate 11, thus increasing the heat exchange area between the wort and the heating element, improving heat exchange efficiency, and greatly reducing the temperature difference within the entire heating pot body 1.

[0030] Example 3 The material boiling pot provided in Example 2 has been further optimized. For details, please refer to [link / reference needed]. Figures 1-4A curved steam pipe is installed on the top of the heating pot body 1. The curved steam pipe includes a first vertical pipe 12, a horizontal pipe 13, and a second vertical pipe 14. One end of the first vertical pipe 12 is connected to the interior of the heating pot body 1, one end of the horizontal pipe 13 is connected to the other end of the first vertical pipe 12, and the other end of the horizontal pipe 13 is connected to one end of the second vertical pipe 14. A spiral pipe 15 is installed on the other end of the second vertical pipe 14. A shell 16 is covered on the spiral pipe 15, and a heat exchange cavity is formed between the spiral pipe 15 and the shell 16. A liquid replenishment pipe 17 connected to the lower part of the shell 16 and a liquid inlet pipe 18 connected to the upper part of the shell 16 are installed on the shell 16. The output end of the liquid inlet pipe 18 extends into the heating pot body 1. Furthermore, both the first vertical pipe 12 and the second vertical pipe 14 are parallel to the vertical direction.

[0031] In the material boiling kettle provided in this embodiment, the steam generated during the wort boiling process enters the curved steam pipe. Under the action of the first vertical pipe 12, the horizontal pipe 13, and the second vertical pipe 14, the steam moves upward along the first vertical pipe 12 and then downward through the horizontal pipe 13 and the second vertical pipe 14 to prevent the water formed after steam condensation from falling back into the heating pot body 1. When the wort level in the heating pot body 1 drops due to discharge or other reasons and needs to be replenished, the new wort is pumped into the heat exchange chamber through the replenishment pipe 17 via an external pressurizing device. After the steam enters the spiral pipe 15, it can heat the wort in the heat exchange chamber. The heated wort then enters through the inlet pipe 18. The new wort enters the heating pot 1, thus preheating it and increasing its temperature. This prevents significant temperature fluctuations within the heating pot 1. Simultaneously, the low-temperature wort entering the heat exchange chamber absorbs heat from the spiral tube 15, cooling and liquefying the steam within the spiral tube 15, facilitating the absorption of the liquefied water. In another embodiment, if the steam after passing through the spiral tube 15 remains gaseous, the output end of the spiral tube 15 can be connected to the input end of the air inlet pipe 21, utilizing the residual heat of the steam to heat the interior of the heating pot 1, further reducing its energy consumption.

[0032] The process of using the material boiling pot provided by this utility model is as follows: the wort in the heating pot 1 is boiled by the heating component. The circulating pump 5 pressurizes the wort at the bottom of the heating pot 1 and injects it into each distribution pipe 7 through the hollow shaft 2 and the liquid distribution chamber 6. The pressurized wort is sprayed out through each nozzle 10 and acts on the anti-splash plate 11. After being splashed by the anti-splash plate 11, the wort is dispersed and falls from the top of the heating pot 1 to the bottom of the heating pot 1. At the same time, the reaction force generated during the wort splashing process drives the spray plate 3 to rotate. The spray plate 3 drives the stirring shaft 8 and the stirring paddle 9 to rotate. The stirring paddle 9 stirs the wort in the heating pot 1. The steam generated by the evaporation of wort is discharged through the bent steam pipe. The wort after boiling can be discharged through the drain pipe, thus realizing the boiling treatment of wort.
