Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a production line for ultraviolet sterilization of wolfberry pulp. Background Technology

[0002] With the increasing demand for natural and healthy beverages, goji berry juice, as a functional drink rich in nutrients and retaining the original flavor of goji berries, has gradually gained widespread market attention. In the industrial production of goji berry juice, sterilization is a crucial step in ensuring product safety and extending shelf life. Traditionally, heat sterilization methods such as pasteurization and high-temperature instantaneous sterilization are widely used in the processing of liquid foods. These methods effectively eliminate bacteria and microorganisms, ensuring product safety.

[0003] However, while high-temperature sterilization effectively kills pathogens, it can also lead to the inactivation or denaturation of active ingredients in goji berry juice, thus affecting its nutritional value and taste. Furthermore, high-temperature treatment can cause color changes and flavor loss, reducing the quality of the final product. Therefore, finding a method that can efficiently sterilize without damaging goji berry juice has become particularly important. In recent years, ultraviolet (UV) sterilization, as a non-thermal treatment method, has been increasingly used in the food industry. It achieves sterilization by destroying the DNA structure of microorganisms with specific wavelengths of UV light. It has advantages such as no heating required, no chemical residue, and simple operation, making it particularly suitable for the sterilization of temperature-sensitive liquid foods such as goji berry juice.

[0004] Therefore, it is necessary to design a UV sterilization production line for wolfberry pulp to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0021] Example: A UV sterilization production line for wolfberry pulp, such as... Figures 1-4As shown, the system includes a support frame 11, a storage tank 1, a feed valve 101, an observation window 102, a first motor 5, a stirring assembly 6, a connecting pipe 3, a variable frequency metering pump 4, a sterilization drum mechanism 2, a discharge valve 7, and an integrated controller 12. The storage tank 1 is bolted to the top right side of the support frame 11. The feed valve 101 is connected to and communicates with the upper right side of the storage tank 1. Observation windows 102 made of transparent material are opened at four positions in the middle of the storage tank 1. A first motor 5 with an output shaft vertically downward and penetrating the top of the storage tank 1 is installed on the top of the storage tank 1. The motor 5 has a stirring assembly 6 connected to its output shaft by bolts. The stirring assembly 6 is located inside the storage tank 1. The bottom left side of the storage tank 1 is connected to and connected to a connecting pipe 3. A variable frequency metering pump 4 is installed on the upper part of the connecting pipe 3. A sterilization roller mechanism 2 is provided on the top left side of the support frame 11. A discharge valve 7 is connected to and connected to the left side of the sterilization roller mechanism 2. An integrated controller 12 is installed on the top right side of the support frame 11 at the lower front position of the storage tank 1. The variable frequency metering pump 4 and the first motor 5 are both electrically connected to the integrated controller 12.

[0022] like Figures 1-5 As shown, the sterilization roller mechanism 2 includes an outer cover 21, a transparent roller 23, ultraviolet lamps 22, and spiral lifting plates 231. The outer cover 21 is connected to the top left side of the support frame 11 by bolts. The transparent roller 23 is rotatably connected inside the outer cover 21. Multiple ultraviolet lamps 22 are arranged in a ring between the transparent roller 23 and the outer cover 21. The inner wall of the outer cover 21 is coated with a reflective coating to enhance the ultraviolet reflection effect. The right sides of the outer cover 21 and the transparent roller 23 are connected and communicated with the connecting pipe 3, respectively. The lower left side of the outer cover 21 is connected and communicated with the discharge valve 7. Three spiral lifting plates 231 extending in the spiral direction are integrally formed inside the transparent roller 23. The ultraviolet lamps 22 are electrically connected to the integrated controller 12.

[0023] like Figures 1-4 As shown, it also includes a second motor 8, a driving gear 9, and a driven gear ring 10. The second motor 8, with its output shaft pointing horizontally to the right, is connected to the top left side of the outer cover 21 by bolts. The driving gear 9 is connected to the output shaft by bolts. A contact groove is provided at the position corresponding to the driving gear 9 on the top left side of the outer cover 21. The driven gear ring 10 is provided on the outer left side of the transparent roller 23. The driven gear ring 10 meshes with the driving gear 9 through the contact groove. The second motor 8 is electrically connected to the integrated controller 12.

[0024] Operators can apply the corresponding technical solutions in this device to the ultraviolet sterilization technology in the continuous production of goji berry pulp, depending on the specific circumstances. When this device is needed to assist in the sterilization of goji berry pulp, firstly, the goji berry pulp to be treated is conveyed to the storage tank 1 through the feed valve 101. Under the control of the integrated controller 12, the first motor 5 is started to drive the stirring component 6 to uniformly stir the pulp, so as to prevent material sedimentation and improve the stability of subsequent conveying.

[0025] Subsequently, the variable frequency metering pump 4 accurately extracts the raw pulp from the connecting pipe 3 according to the set parameters and stably delivers it to the sterilization drum mechanism 2. The sterilization drum mechanism 2 consists of an outer cover 21, a transparent drum 23, and annularly arranged ultraviolet lamps 22. When the raw pulp flows through the inside of the transparent drum 23, it is irradiated by the high intensity of multiple sets of ultraviolet lamps 22, thereby achieving efficient sterilization treatment without chemical residue.

[0026] To enhance sterilization and material flowability, the transparent drum 23 is equipped with three spiral lifting plates 231 extending in a spiral direction, causing the slurry to be distributed in a spiral shape within the drum and extending its residence time in the ultraviolet irradiation area. Simultaneously, the second motor 8 drives the drive gear 9 to rotate, which meshes with the driven gear ring 10 on the outer ring of the transparent drum 23, causing the entire transparent drum 23 to rotate slowly, ensuring uniform irradiation of the slurry and avoiding incomplete sterilization in certain areas.

[0027] During the operation of the sterilization drum mechanism, the ultraviolet light emitted by the ultraviolet lamps not only directly irradiates the goji berry pulp flowing through the transparent drum, but also projects some light onto the inner wall of the outer casing. Because the inner casing is made of reflective material, it effectively reflects ultraviolet light that might otherwise be absorbed or scattered back to the transparent drum area, thereby increasing the ultraviolet intensity and utilization rate per unit area inside the drum. This structural design enhances the sterilization effect, allowing the goji berry pulp to receive more sufficient ultraviolet irradiation in a shorter time, further improving sterilization efficiency and uniformity.

[0028] After sterilization, the goji berry pulp is discharged through discharge valve 7 and enters the next process. Throughout the operation, operators can monitor the material status in storage tank 1 in real time through observation window 102 to ensure normal system operation. All actuators are uniformly coordinated and managed by integrated controller 12, realizing automated control and process adjustment of equipment operation, improving sterilization efficiency and product quality consistency.
