[0027] Embodiment 1

[0028] This embodiment provides an energy-saving and environmentally friendly multi-pass special evaporation device for brewing. As one of the components of the split-type brewing evaporator, a steamer cover 24 and a condensing pipe 25 are installed at the top of the evaporation device. The condensing pipe 25 is connected to a condenser 26, and the distilled wine vapor enters the condenser 26 through the condensing pipe for storage.

[0029] Refer to Figures 1-5 , including a base 1, a steamer barrel 2, and a heating element 3;

[0030] The base 1 is made of high-temperature resistant materials such as 304 stainless steel, or high-temperature resistant 310S stainless steel, or heat-resistant alloy, with good corrosion resistance and strength, ensuring safety and lifespan in high-temperature environments;

[0031] The base 1 is of an overall rectangular structure, with a circular opening in the center. The steamer barrel 2 is embedded in the circular opening of the base 1 by welding.

[0032] The steamer barrel 2 is of a hollow structure. The bottom of the steamer barrel 2 is a steam chamber 16, and a heating component is arranged inside the steam chamber 16. The heating component is at a certain distance from the bottom of the steamer barrel. Liquid raw materials (yellow water, spent liquor, and clear water) are contained inside the steam chamber 16, and the water level line 28 of the liquid raw materials is higher than the heating component, and the heating component needs to be immersed; above the steam chamber 16 is a fermentation material tank 17; a porous partition 15 is arranged between the fermentation material tank 17 and the steam chamber 16. An annular boss 14 is arranged on the inner wall of the steamer barrel. The porous partition 15 is placed on the annular boss 14, and the inside of the steamer barrel is partitioned through the porous partition 15. The area below the porous partition is the steam type, and the area above is the fermentation material tank 17. Distillers' grains 27 are contained inside the fermentation material tank 17. The heated steam volatilizes upward through the hole partition into the fermentation material tank 17. The distillers' grains 27 in the upper fermentation material tank 17 are steam-distilled, and the distillers' grains 27 are distilled through the steam of yellow water, spent liquor, and clear water to extract flavor substances into the wine body, and can also make the wine body flavor more intense.

[0033] A water pipe 13 for both water injection and drainage is also arranged at the bottom of the steamer barrel 2. The water pipe 13 is communicated with the steam chamber 16. The other end of the water pipe 13 far from the steam chamber 16 is provided with a water inlet branch pipe 18 and a drainage branch pipe 19. The water inlet branch pipe 18 and the drainage branch pipe 19 are arranged in parallel. A check valve 20, a water pump 21, and a water tank 22 are sequentially connected on the water inlet branch pipe 18, and a drainage valve 23 is arranged on the drainage branch pipe 19.

[0034] A water level observation pipe 29 is also arranged on the side of the steamer barrel. The water level observation pipe 29 is communicated with the steam chamber, facilitating direct observation of the water level inside the steam chamber 16 and preventing dry burning.

[0035] The heating element 3 includes a combustion chamber 12, and a multi-pass flame channel 4 is arranged inside the combustion chamber 12. The design of the flame channel prolongs the residence time of the flame during the flowing process, thereby improving the heat exchange efficiency.

[0036] The combustion chamber 12 is externally connected to a burner and an exhaust pipe 5. The burner provides a stable flame, and the flame circulates in the multi-pass flame channel 4 to ensure sufficient heating of the liquid.

[0037] The present technical solution has the following technical effects:

[0038] Because the multi-pass flame channel 4 structure is adopted in the combustion chamber 12 of the present device, the heating area of the liquid outside the combustion chamber 12 is relatively large, and the heat exchange efficiency of the present invention is 30% higher than that of traditional boilers. This not only shortens the evaporation time but also saves energy consumption.

[0039] Embodiment 2

[0040] On the basis of the above Embodiment 1, the design of the retort 2 and its related components is further optimized as follows. Refer to Figures 1-5 :

[0041] A retort cover and a condensing pipe are installed on the top of the retort 2, and the condensing pipe is connected to a condenser;

[0042] The retort 2 is made of high-temperature resistant materials such as 304 stainless steel, or high-temperature resistant 310S stainless steel, or heat-resistant alloy, with good corrosion resistance and strength, ensuring safety and service life in a high-temperature environment.

[0043] The retort 2 is a cylindrical container, and the lower half is embedded in the base 1 to enhance stability and safety.

[0044] The heating element 3 is installed at the bottom of the retort 2 and is itself made of a high thermal conductivity material to ensure the heat exchange efficiency between the heating element 3 and the liquid is sufficient, so as to achieve rapid temperature rise and uniform heating.

[0045] A plurality of installation ports are provided on the side wall of the lower half of the retort 2, and a square pipe 6 is arranged on one side of the combustion chamber 12 and is fixedly welded to the installation ports to prevent the liquid in the retort from leaking out.

[0046] A large round pipe is sleeved inside the square pipe, and a small round pipe is sleeved inside the large round pipe. The internal space of the small round pipe is the channel Ⅰ9. One end of the channel Ⅰ9 is communicated with the burner to ensure smooth entry of combustion gas into the flame channel; the other end is communicated with the flame channel inside the combustion chamber, and the fire is sprayed in from inside the small round pipe; the space between the small round pipe and the large round pipe is a sandwich filled with water, which is connected to the liquid outside the combustion chamber;

[0047] The space between the large round pipe and the square pipe is a sandwich, which is the channel Ⅱ10. One end of the channel Ⅱ10 is communicated with the flame channel inside the combustion chamber, and the other end is connected to the exhaust pipe.

[0048] The flame channel is designed as a multi-pass structure, effectively prolonging the flame residence time and improving the heat exchange efficiency.

[0049] Example 3

[0050] Based on the above-mentioned Embodiment 1 and Embodiment 2, the design of the multi-pass flame channel 4 is further optimized as follows. Refer to Figures 1-5 :

[0051] The multi-pass flame channel 4 includes a main channel 7 and "Z"-shaped sub-channels 8 symmetrically and continuously arranged on both sides of the main channel 7. One end of the main channel 7 is connected to the channel I 9, and the other end is connected to the sub-channel 8; the end of the sub-channel 8 far from the main channel 7 is connected to the exhaust pipe 5 through the channel II 10.

[0052] The main channel 7 is the main flow path of the combustion flame. One end is connected to the channel I 9 of the burner, and the other end is connected to the sub-channels 8 on both sides. The cross-sectional shape of the main channel 7 should be designed to be streamlined to reduce the flow resistance and ensure the smooth flow of the combustion flame.

[0053] Continuous "Z"-shaped sub-channels 8 are symmetrically arranged on both sides of the main channel 7. The side walls of each sub-channel 8 present a "Z"-shaped structure, and the "Z"-shaped structure of the sub-channel 8 forms a plurality of gaps between the side walls. These gaps can effectively increase the contact area between the flame and the fluid and improve the heat exchange efficiency. When designing, the sizes of these gaps need to be calculated to ensure that the fluid can flow fully in the sub-channel 8.

[0054] An interface 11 connected to the burner is provided on the square pipe 6. The design of the interface 11 needs to ensure the sealing performance to prevent gas leakage. The interface 11 can adopt a quick-connection design for easy maintenance and replacement.

[0055] The burner is communicated with the channel I 9 in the square pipe 6 through the interface 11. The flame in the burner enters the main channel 7 through the channel I 9, and then is evenly transported to the sub-channels 8 on both sides of the main channel 7. The sub-channel 8 is of a "Z"-shaped structure, and a number of gaps are formed between the side walls of the "Z"-shaped structure, which can greatly increase the contact area between the flame channel and the liquid, increase the heat exchange efficiency, and the generated flue gas after acting is connected to the exhaust pipe 5 through the channel II 10.

[0056] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
