TECHNICAL FIELD

[0001] The utility model relates to a kind of high-efficiency energy-saving dealcoholization equipment, belong to beer production technical field. BACKGROUND

[0002] Beer as a kind of world's drink, due to its special nutritional value, and containing various amino acids and other nutrients required by human body, whether it is beer production, or sales all are in the forefront in various wine, has become an indispensable part in people's life. But beer as a kind of alcoholic beverage, drink too much can be harmful to liver and other human organs. At this time, people begin to keenly demand new brewing technology to produce a kind of low-alcohol, even alcohol-free beer to replace traditional beer.

[0003] Traditional beer dealcoholization method is divided into two categories, one is vacuum distillation method, one is fermentation inhibition method. Vacuum distillation method needs to be heated to 30-50°C, resulting in a large number of losses of volatile flavor substances (such as esters, terpenes), and there is a problem of high energy consumption (≥50kWh per ton of processing). Fermentation inhibition method is to change fermentation strain or process conditions in brewing process, to limit the amount of alcohol production in production process. Because the method changes the original brewing process, the taste of the alcohol-free beer produced is greatly different from that of ordinary beer, and the sugar residue is high, the taste is sweet and greasy, leading to consumer's difficulty in accepting.

[0004] From the above, it is obvious that the prior art has inconvenience and defects in actual use, so it is necessary to improve. CONTENT OF THE UTILITY MODEL

[0005] The utility model in prior art provides a kind of high-efficiency energy-saving dealcoholization equipment, can reduce ethanol content in beer by physical separation method, retain the original flavoring substance and nutrient component of beer simultaneously, dealcoholization efficiency is high, and energy consumption is low.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A kind of high-efficiency energy-saving dealcoholization equipment, including multiple membrane shells arranged side by side, the inclined reverse osmosis membrane of being installed in membrane shell, the end of membrane shell away from reverse osmosis membrane is connected with raw liquid inlet pipe, the end of membrane shell close to reverse osmosis membrane is connected with permeate delivery pipe and concentrated solution delivery pipe respectively;Raw liquid inlet pipe is successively equipped with booster pump, precision filter and high-pressure pump;The delivery end of concentrated solution delivery pipe is connected with the top of circulating tank inner chamber, and heat exchanger and wine mixer are successively installed on concentrated solution delivery pipe.

[0008] Further, the membrane shell is arranged along the transverse direction.

[0009] Furthermore, the reverse osmosis membrane is a composite polyamide membrane.

[0010] Furthermore, the precision filter is equipped with a PP cotton filter element.

[0011] Furthermore, one end of the heat exchanger is connected to the cooling water inlet pipe, and the other end is connected to the cooling water outlet pipe.

[0012] Furthermore, the beverage mixer is also connected to a deoxygenated water inlet pipe.

[0014] Furthermore, the bottom of the circulation tank is connected to the deethanolated wine delivery pipe.

[0015] Furthermore, the delivery end of the permeate delivery pipe is connected to the permeate tank.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0017] The beer concentrate is first pumped into a precision filter for pre-filtration to remove particles that may clog the reverse osmosis membrane. Then, it is pushed by a high-pressure pump through the reverse osmosis membrane inside the membrane housing. The reverse osmosis membrane effectively separates the ethanol. The separated dealcoholized beer is then temperature-controlled by a heat exchanger and enters the beer-water mixer. After being mixed with deoxygenated water, it enters the circulation tank.

Detailed Implementation

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] like Figure 1 As shown, this utility model provides a high-efficiency and energy-saving de-alcoholization device, including multiple membrane housings 1 arranged side by side. The membrane housings 1 are arranged horizontally, and each membrane housing 1 is equipped with an inclined reverse osmosis membrane 2. The end of the membrane housing 1 away from the reverse osmosis membrane 2 is connected to the feed liquid inlet pipe 3, and the end of the membrane housing 1 close to the reverse osmosis membrane 2 is connected to the permeate delivery pipe 7 and the concentrate delivery pipe 9 respectively.

[0026] The reverse osmosis membrane 2 is a composite polyamide membrane, which achieves efficient separation of ethanol (retention rate ≥90%) while retaining flavor substances (retention rate ≤10%).

[0027] The raw liquid inlet pipe 3 is sequentially equipped with a booster pump 4, a precision filter 5, and a high-pressure pump 6. The precision filter 5 is equipped with a PP cotton filter element.

[0028] The booster pump 4 pumps the beer concentrate into the precision filter 5, which pre-filters the beer concentrate to remove particles that may clog the reverse osmosis membrane 2. The high-pressure pump 6 provides sufficient pressure to push the beer through the reverse osmosis membrane 2.

[0029] The end of the concentrated liquid delivery pipe 9 is connected to the top of the inner cavity of the circulation tank 12, and a heat exchanger 10 and a wine-liquid mixer 11 are installed on the concentrated liquid delivery pipe 9 in sequence.

[0030] One end of the heat exchanger 10 is connected to the cooling water inlet pipe 13, and the other end is connected to the cooling water outlet pipe 14. The heat exchanger 10 is used to regulate the temperature of the concentrate in real time, keeping it at 10-20°C to prevent loss of flavor components and ensure the de-alcoholization effect.

[0031] The beverage mixer 11 is also connected to the deoxygenated water inlet pipe 15. After the deoxygenated water and concentrate are mixed by the beverage mixer 11, they enter the circulation tank 12.

[0032] The top of the circulation tank 12 is also connected to a carbon dioxide inlet pipe 16 and an exhaust pipe 17.

[0033] The bottom of the circulation tank 12 is connected to the dealcoholized spirits conveying pipe 18, through which the dealcoholized spirits are sent to bottling or post-processing.

[0034] The end of the permeate delivery pipe 7 is connected to the permeate tank 8, and the filtered ethanol enters the permeate tank 8 for storage.

[0035] The specific working principle of this utility model is as follows:

[0036] The beer concentrate is first pumped into the precision filter 5 by the booster pump 4. The precision filter 5 pre-filters the beer concentrate to remove particles that may clog the reverse osmosis membrane 2. The high-pressure pump 6 provides sufficient pressure to push the beer through the reverse osmosis membrane 2 inside the membrane housing 1. The reverse osmosis membrane 2 effectively separates the ethanol. The beer after de-alcoholization is temperature controlled by the heat exchanger 10 and then enters the beer-water mixer 11. The deoxygenated water and the de-alcoholized beer are mixed in the beer-water mixer 11 and then enter the circulation tank 12. The de-alcoholized beer in the circulation tank 12 is sent to bottling or post-processing via the de-alcoholized beer delivery pipe 18. The ethanol filtered by the reverse osmosis membrane 2 is stored in the permeate tank 8.

[0037] This invention reduces the ethanol content in beer through physical separation (the de-alcoholization rate can reach over 95%), while retaining the original flavor substances (such as esters, phenols, organic acids, etc.) and nutrients (such as amino acids and B vitamins) of the beer. It is suitable for producing non-alcoholic beer (ABV≤0.5%) or low-alcohol beer (ABV≤1.2%).
