Description

Technical Field

[0001] This invention belongs to the technical field of peanut beverage preparation equipment, specifically a device and method for preparing freshly squeezed peanut juice beverage. Background Technology

[0002] In recent years, with the increasingly fast pace of life and rising living standards, people are pursuing healthier diets, especially favoring plant-based foods, particularly plant-based protein foods with health and medicinal benefits. Due to their unique taste, effects, and good health benefits, peanuts have become an ideal raw material for producing health supplements.

[0003] Fresh peanuts are rich in various vitamins, amino acids, and trace elements essential for the human body. Studies have shown that when peanuts undergo secondary processing, such as dehydration, boiling, or frying, a significant amount of nutrients are lost, reducing their nutritional value. Therefore, when using peanuts as a raw material for beverage preparation, direct pressing of fresh peanuts maximizes the retention of essential amino acids and vitamins. However, in actual peanut beverage preparation, it has been found that peanuts are prone to carrying aflatoxin, resulting in a higher probability of aflatoxin contamination in the juice extracted from freshly pressed peanuts. Aflatoxin is heat-resistant, difficult to degrade, and highly toxic, thus posing a technical challenge to the preparation of beverages from fresh peanuts.

[0004] In related technologies, to prevent aflatoxin contamination of peanut products from peanuts, ultraviolet (UV) irradiation of specific wavelengths is often used to degrade aflatoxin in peanut products. For example, a Chinese patent, application number 2018105980606, describes an automatic control circulating peanut oil aflatoxin degradation machine. This solution uses UV irradiation on peanut oil, one of the peanut products, to kill and degrade bacteria and aflatoxin in the peanut oil. However, when using UV sterilization on peanut slurry prepared from freshly ground peanuts, it was found that because peanut slurry is a suspension with many solid particles, UV transmission is difficult, resulting in reduced efficiency in killing and degrading bacteria and aflatoxin in the peanut slurry. Therefore, this invention proposes a device and method for preparing freshly squeezed peanut juice beverages to solve the above-mentioned technical problems.

Detailed Implementation

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] like Figures 1 to 10 As shown, the apparatus and method for preparing freshly squeezed peanut juice beverage according to the present invention includes a sterilization tank 1 and a sterilization lamp tube 11. The sterilization lamp tube 11 is installed inside the sterilization tank 1. A feed pipe 12 is installed at the bottom of the sterilization tank 1. The sterilization lamp tube 11 adopts an ultraviolet sterilization lamp core.

[0045] It also includes an atomizing sterilization component, which is installed inside the sterilization tank 1 and is used to enhance the contact efficiency between ultraviolet light and peanut juice.

[0046] The atomizing sterilization component includes a booster pump 2, which is installed on the sterilization tank 1 and is used to extract peanut juice from inside the sterilization tank 1.

[0047] Atomizing nozzle 21 is connected to the output end of booster pump 2. The atomizing nozzle 21 is a tubular structure with multiple atomizing nozzles. The atomizing nozzle 21 is used to atomize and spray peanut juice into sterilization tank 1.

[0048] The sterilization lamp tubes 11 are designed in multiples and are evenly arranged inside the sterilization tank 1. The atomizing nozzle extends to the top of the sterilization lamp tubes 11.

[0049] Separation disc 22 is installed inside sterilization tank 1, and the separation disc 22 divides sterilization tank 1 into atomization chamber 23 and circulation chamber 24.

[0050] The liquid outlet pipe 25 is fixedly installed on the separation plate 22, and the liquid outlet pipe 25 is externally connected to the peanut juice storage container;

[0051] A flow guide plate 26 is fixedly installed inside the sterilization tank 1 via a guide rod. An annular groove 27 is provided on the flow guide plate 26. A retaining ring 28 is rotatably installed in the annular groove 27. The retaining ring 28 is rotatably and sealingly installed in the annular groove 27. The atomizing nozzle 21 is fixedly installed on the retaining ring 28. The atomizing nozzle 21 and the booster pump 2 are both designed to be connected to the annular groove 27. The atomizing nozzles are all arranged along the circumference of the retaining ring 28.

[0052] In the peanut juice preparation process, fresh peanuts are ground into juice, and after settling and filtering, the raw peanut juice is produced. Before secondary processing, it needs to be sterilized and disinfected to reduce harmful substances such as bacteria and aflatoxin in the peanut juice, thus facilitating the storage and secondary processing of the peanut juice. When disinfecting the peanut juice, ultraviolet disinfection is used because it is environmentally friendly, safe, has few side effects, and has excellent degradation effect on aflatoxin. While disinfecting the peanut juice, it reduces damage to the peanut juice. In addition, by setting up an atomizing sterilization component in this application, compared with the traditional flow-through disinfection method, the ultraviolet light acts more evenly and comprehensively on the peanut juice, thereby enhancing the removal of harmful substances such as bacteria and aflatoxin in the peanut juice.

[0053] Specifically, during the sterilization of peanut juice, the filtered peanut juice is introduced into the circulation chamber 24 of the sterilization tank 1 through the inlet at the bottom of the sterilization tank 1. Simultaneously, the sterilization lamp 11 located in the sterilization tank 1 is activated, emitting ultraviolet light of a specific wavelength. This ultraviolet light irradiates the peanut juice, destroying the structure of bacteria and aflatoxin, thus achieving sterilization. At the same time, the atomizing sterilization component is activated. The booster pump 2 in the atomizing sterilization component draws the peanut juice from the circulation chamber 24 and, after pressurization, pumps it into the annular groove 27 and the atomizing nozzle 21. The atomizing nozzle on the atomizing nozzle 21 sprays the peanut juice into the atomizing chamber 23. Under pressure, the peanut juice breaks down into evenly distributed small droplets, which then disperse downwards under gravity. During this process, the ultraviolet light emitted by the sterilization lamp 11 irradiates the atomized... In the peanut juice, the atomization of the peanut juice enhances the penetration effect of the ultraviolet light beam, causing the atomized peanut juice to come into uniform contact with the ultraviolet light beam, thereby achieving comprehensive disinfection and sterilization of the atomized peanut juice. At the same time, when the atomizing nozzle sprays the peanut juice, under the action of the reaction force, the atomizing nozzle 21 has a tendency to move in the opposite direction. Since the atomizing nozzle 21 is fixedly installed on the baffle ring 28, and the baffle ring 28 is rotatably connected to the guide plate 26 through the annular groove 27, the reaction force causes the atomizing nozzle 21 to rotate. The rotation of the atomizing nozzle 21 causes the atomized peanut juice to be evenly sprayed on the top of the atomizing chamber 23, and gradually aggregates and condenses to form peanut juice during the downward settling process. After being intercepted by the separation plate 22, the peanut juice is collected by the separation plate 22 and enters the liquid outlet pipe 25, and flows to the next process through the liquid outlet pipe 25.

[0054] This invention, by setting up an atomizing sterilization component, uses a booster pump 2, an atomizing nozzle 21, and an atomizing head to break liquid peanut juice into atomized droplets, thereby enhancing the penetration of ultraviolet light into the peanut juice and ensuring uniform contact between the peanut juice and ultraviolet light. Compared to flow-through sterilization, this effectively enhances the comprehensiveness of peanut juice disinfection and sterilization. At the same time, the rotation of the atomizing nozzle 21 ensures that the atomized peanut juice is more evenly dispersed and distributed within the atomizing chamber 23, further enhancing the uniformity of peanut juice treatment.

[0055] As a preferred embodiment of the present invention, it further includes an efficiency adjustment component, which is installed inside the sterilization tank 1 and is used to adjust the peanut juice sterilization efficiency.

[0056] The efficiency adjustment component includes a control rod 3, which is fixedly installed inside the sterilization tank 1. The control rod 3 has evenly distributed pressing grooves 31 at equal intervals. Each pressing groove 31 is equipped with a push-button switch 32. The multiple push-button switches 32 are used to control the output power of the sterilization lamp tube 11. The separation plate 22 has a through groove 33. The separation plate 22 is slidably connected to the control rod 3, the transmission rod 44, and the sterilization lamp tube 11 through the through groove 33. The push-button switches 32 are positioned corresponding to the separation plate 22 and are located on the movement path of the separation plate 22. The density of the separation plate 22 is less than that of peanut juice.

[0057] The separation disk 22 has a tapered cross-section, with a high center and low edges. Multiple isolation rings 34 are fixedly installed on the separation disk 22, and the isolation rings 34 correspond one-to-one with the through grooves 33.

[0058] In the peanut juice production line process, the filtered peanut juice is directly drawn into the circulation chamber 24. The supply rate of the peanut juice is uneven. Therefore, an efficiency adjustment component is installed to adjust the sterilization efficiency based on the peanut juice supply rate, thus making the equipment conform to the energy-saving and environmentally friendly production concept. Specifically, after the peanut juice enters the circulation chamber 24, as the liquid level gradually rises, the separation plate 22, which is slidably installed in the sterilization tank 1, rises. Under the action of buoyancy, the separation plate 22 always floats on the surface of the peanut juice. During the up-and-down movement of the separation plate 22, a relative displacement occurs between the separation plate 22 and the control rod 3. Multiple press-activated switches are installed in the pressing groove 31 on the control rod 3. These multiple press-activated switches 32 correspond to different power levels of the sterilization lamps 11. Under the control of a pre-set program, when a press-activated switch 32 is pressed, a corresponding command is sent, causing the power of the sterilization lamps 11 to be adjusted to the preset value. Therefore, the peanut juice in the sterilization tank 1... When the liquid level changes, as the peanut juice feed rate increases, the liquid level rises continuously. The separation plate 22 rises under buoyancy, and during the rise, multiple push-button switches 32 are pressed sequentially according to the rising distance, causing the power of the sterilization lamp 11 to increase sequentially. Conversely, when the feed rate decreases, the peanut juice level drops, and the power of the sterilization lamp 11 gradually decreases. It should be noted that the suction power of the booster pump 2 remains constant in this invention. When the liquid level in the sterilization tank 1 is low, the power of the sterilization lamp 11 is low, but because the height of the atomization chamber 23 is relatively large, the distance from which the atomized peanut juice falls onto the separation plate 22 is relatively long. When the liquid level in the sterilization tank 1 is high, the power of the sterilization lamp 11 is high, but because the height of the atomization chamber 23 is relatively low, the falling path of the peanut juice is short. Therefore, the disinfection and sterilization effect of the peanut juice remains consistent throughout the sterilization process, and the power adjustment makes the equipment conform to the production concept of energy conservation and emission reduction.

[0059] In a preferred embodiment of the present invention, a perforated plate 4 is slidably installed inside the sterilization tank 1, and a plurality of scraper rings 41 are fixedly embedded on the perforated plate 4. An annular scraper blade 42 is fixedly installed on the inner wall of the scraper ring 41, and the annular scraper blade 42 is interference-fitted with the sterilization lamp tube 11.

[0060] A transmission ring 43 is fixedly installed at the bottom of the atomizing nozzle 21. A transmission rod 44 is rotatably installed inside the sterilization tank 1. The transmission rod 44 extends into the inner cavity of the transmission ring 43, and a transmission wheel 45 is fixedly installed in the inner cavity of the transmission ring 43. The transmission rod 44 is a reciprocating screw, and a nut 5 is helically installed on the transmission rod 44. The nut 5 is connected to the hollow plate 4.

[0061] A limiting plate 51 is fixedly installed inside the sterilization tank 1. The limiting plate 51 is slidably connected to the nut 5. The limiting plate 51 is used to restrict the rotation of the nut 5. A magnetic ring 52 is embedded in the hollow plate 4. The magnetic ring 52 cooperates with the nut 5. The nut 5 is detachably fixedly connected to the scraper ring 41 through the magnetic ring 52.

[0062] The number of transmission rods 44 is at least two and they are evenly divided into two groups; the number of hollow plates 4 is two and they are respectively installed on both sides of the separation plate 22.

[0063] As the atomizing nozzle 21 rotates continuously under the action of the reaction force, the transmission ring 43, which is fixedly installed with the atomizing nozzle 21, rotates. The transmission ring 43 meshes with the transmission wheel 45, which is fixedly installed on the transmission rod 44. Therefore, during the rotation of the atomizing nozzle 21, the transmission rod 44 is driven to rotate. The nut 5, which is screw-driven and installed on the transmission rod 44, then moves back and forth under the restriction of the limiting plate 51. When the nut 5 aligns with the magnetic ring 52 on the perforated plate 4, the nut 5 engages with the perforated plate 4 under the action of magnetic attraction, thereby driving the perforated plate 4 to move up and down within the sterilization tank 1. During the up and down movement, the perforated plate 4 scrapes the sterilization lamp tube 11 through the scraping ring 41 and the annular scraper 42. The scraping action removes the peanut juice mist adhering to the sterilization lamp tube 11 in the atomizing chamber 23, promoting the outflow of the sterilized peanut juice and enhancing the penetration of ultraviolet light into the peanut juice mist. Meanwhile, the movement of the perforated plate 4 below the separation plate 22 enhances the flow of peanut juice in the circulation chamber 24, achieving pre-sterilization of the peanut juice. It should be noted that when the nut 5 moves to the separation plate 22, it gradually separates from the current separation plate 22 due to the obstruction of the separation plate 22. When it moves to the other side of the separation plate 22, it drives the other perforated plate 4 to move. Through the alternating movement of the two nuts 5, the nuts 5 and the separation plate 22 are alternately engaged.

[0064] In a preferred embodiment of the present invention, a suction pipe 6 is fixedly installed on the separation plate 22, and the suction pipe 6 is designed to have an opening on the bottom surface of the separation plate 22. The suction pipe 6 is fixedly connected to the input end of the booster pump 2.

[0065] The suction pipe 6 is designed so that the booster pump 2 always draws peanut juice from the area near the separation plate 22, and then atomizes and disinfects the peanut juice in the circulation chamber 24 in sequence.

[0066] A method for preparing a freshly squeezed peanut juice beverage, the method comprising the following steps:

[0067] S1: Select fresh and plump peanut kernels, and after washing, air separation and rinsing in a bubble washing machine, spread the peanut kernels evenly and send them into the high-speed crusher by belt elevator. Pure mineral water is added at the same time to make the peanuts crushed evenly in an instant.

[0068] S2: The crushed slurry is sent into the airbag belt press, where the concentrated juice is rapidly separated under high pressure. After settling and filtration, the peanut juice is passed into the sterilization tank 1. After being boosted by the booster pump 2, it is sprayed into the atomizing chamber 23 by the atomizing nozzle on the atomizing nozzle pipe 21 and comes into uniform contact with the ultraviolet light beam for sterilization.

[0069] S3: Add 0.2% α-amylase to the sterilized peanut juice and hydrolyze it at 60℃ for 35 min. Add 0.16% protease and hydrolyze it at 45℃ for 40 min. Then add 0.1% xanthan gum, 0.1% CMC, and 0.05% guar gum. Hydrolyze and emulsify the mixture in a mixing tank and preserve it for 15-40 min. After mixing, add white sugar, sterile water, antioxidants, and flavor enhancers and protectants to adjust the volume and flavor.

[0070] S4: Heat the liquid material prepared in S3 to boiling for 10 minutes to inactivate the enzyme in the slurry. Then, perform vacuum degassing and homogenization. After homogenization, heat and sterilize the liquid material again, then cool and pack it into boxes to output the finished peanut juice.

[0071] Specifically, when screening peanuts, the raw peanuts should be fresh and plump, and they should be carefully selected to remove impurities and moldy particles, so as to minimize the introduction of aflatoxin into the product.

[0072] During pulp-residue separation, peanut pulp is filtered through four layers of gauze to remove residue.

[0073] During enzymatic hydrolysis and emulsification, the addition of amylase and protease can improve the stability of peanut beverages. At the same time, through single-factor and orthogonal experiments on temperature, time, enzyme concentration, and pH, the optimal enzyme treatment conditions were determined. The optimal process is: α-amylase addition of 0.2%, enzymatic hydrolysis at 60℃ for 35 min; protease addition of 0.16%, enzymatic hydrolysis at 45℃ for 40 min.

[0074] Emulsification and stabilization treatments, along with the addition of stabilizers, can improve the stability of peanut beverages. The order of influence of xanthan gum, CMC, and guar gum on the stability of peanut beverages is: xanthan gum > CMC > guar gum. The optimal combination of stabilizers is: xanthan gum 0.10%, CMC 0.10%, and guar gum 0.05%. Enzymatic emulsification and storage in a mixing tank for 15-40 minutes are recommended.

[0075] Antioxidants and flavor enhancers are added to fruit juice for three reasons: first, to protect the vitamins in the juice; second, to protect the aroma components in the juice; and third, to facilitate full dissolution and maximize their effectiveness.

[0076] Homogenization is a key process for improving the taste and stability of peanut beverages. The homogenization temperature is 25℃-55℃, and the pressure is 25-40MPa.

[0077] Vacuum degassing uses low vacuum to remove oxygen and unpleasant odors from the product, thereby ensuring stable product quality. High-pressure homogenization can reduce the particle size of dispersed particles and the radius of fat globules, while allowing emulsifying stabilizers to play their full role.

[0078] Preferably, the degassing temperature in S4 is 55–60°C;

[0079] Preferably, the vacuum degree of degassing in S4 is -0.08 to -0.05 MPa;

[0080] The combination of the above specific numerical ranges can enable the removal of gases such as oxygen that affect the composition of the feed liquid during the degassing process, thereby reducing the damage of these gases to the nutrients in the feed liquid.

[0081] Preferably, the homogenization pressure in step S4 is 20-25 MPa, but it is not limited to the listed values. Other unlisted values ​​within the above ranges are also applicable.

[0082] The aforementioned specific homogenizing pressure can fully disperse the solids in the liquid into smaller solid particles, making the product more aesthetically pleasing and with a better taste.

[0083] Preferably, the sterilization temperature in step S4 is 85–90°C;

[0084] Preferably, the sterilization time in step S4 is 15–30 seconds;

[0085] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
