Description

Technical Field

[0001] The utility model relates to the technical field of UHT sterilization equipment, in particular to a juice UHT sterilizer. Background Art

[0002] In the UHT (Ultra High Temperature Instantaneous Sterilization) process, the heat source is the energy source used to heat food or beverages to achieve the purpose of sterilization. Common heat sources include steam, water or gas. These heat sources can provide enough heat to heat food or beverages to the required ultra-high temperature, thereby effectively killing the germs and spores in them and extending the shelf life of the food.

[0003] Steam is a commonly used and efficient heat source because it can transfer heat quickly and evenly and is easy to control and adjust. In UHT sterilizers, steam is usually used to heat liquid products through specially designed heaters, such as tubular or plate heaters. This heating method ensures that the product can reach the required ultra-high temperature in a very short time, thereby achieving an efficient sterilization effect.

[0004] In the production process of UHT sterilization technology, water is often used as a medium for cleaning and disinfecting pipes and equipment. This is because water has excellent solubility and fluidity, and can effectively remove stains, microorganisms and other impurities attached to the inner wall of the pipe. However, after cleaning and disinfection, if it is not thoroughly dried, residual moisture may remain in the pipe. The design and installation of the pipe may also affect the existence of residual moisture. For example, if there are bends, slopes or low-lying parts in the pipe, these areas are prone to accumulate moisture. In addition, there may be small gaps or leaks in pipe joints, valves, flanges and other components, resulting in residual moisture. Utility Model Content

[0005] The utility model aims to provide a juice UHT sterilizer to solve the problem in the above background technology that after cleaning and sterilization, if the drying process is not carried out thoroughly, residual moisture may be left in the pipeline.

[0006] To achieve the above-mentioned purpose, the utility model provides a juice UHT sterilizer, including a UHT sterilization bin, a bottom end of the UHT sterilization bin is connected to a feed pipe, a top end of the UHT sterilization bin is connected to a discharge pipe, an outer end of the discharge pipe is installed with an electric four-way valve, an output port on one side of the electric four-way valve is connected to a material recovery tank through a recovery pipeline, a top output port of the electric four-way valve is connected to a filling pipeline, a discharge pipe is connected to the bottom of the material recovery tank, a valve and a liquid pump are installed on the discharge pipe, and the outer end of the discharge pipe is connected to a re-deployment pipeline.

[0007] Preferably, the other side output port of the recovery pipeline is connected to a circulation pipeline.

[0008] Preferably, a plurality of horizontal tube groups are arranged inside the UHT sterilization chamber, and the ends of the horizontal tube groups are connected in sequence from top to bottom through U-shaped connecting tubes, one end of the uppermost horizontal tube group is connected to the discharge pipe, and one end of the lowermost horizontal tube group is connected to the feed pipe.

[0009] Preferably, a steam inlet is provided at the bottom of the UHT sterilization chamber, and a steam outlet is provided at the top of the UHT sterilization chamber.

[0010] Preferably, the horizontal pipe group consists of a plurality of parallel horizontal pipelines.

[0011] Preferably, a stirring motor is installed on the top of the material recovery tank, a stirring rod is installed on the bottom output shaft of the stirring motor, and a plurality of stirring blades are installed on the outside of the stirring rod.

[0012] Preferably, a feed port is provided on one side of the top of the material recovery storage tank, and a feed port is provided on the other side of the top of the material recovery storage tank, and the outer end of the feed port is connected to the recovery pipeline.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In this juice UHT sterilizer, through its innovative design and process optimization, the sterilization efficiency, product quality and flexibility of the production process are significantly improved. First of all, steam is used as the heat source, combined with the specially designed UHT sterilization chamber and horizontal pipe group, the juice is evenly heated and efficiently sterilized in a very short time, ensuring that the nutritional components and taste of the juice are retained to the maximum extent. The sterilizer is equipped with an electric four-way valve and a recovery pipeline, which can flexibly control the flow direction of the juice and realize the rapid recovery and treatment of unqualified juice. This design not only improves production efficiency, but also reduces material waste, which helps enterprises achieve cost control and sustainable development. The design of the material recovery tank is also quite ingenious. Through the drive of the stirring motor, it can ensure the uniform mixing of the recovered juice, which provides convenience for subsequent processing. At the same time, the setting of the feeding port also allows the recovered juice to be re-deployed as needed, further improving the utilization rate of materials and the diversity of products. The utility model juice UHT sterilizer also fully considers the problem of residual water in the pipeline. Through reasonable pipeline layout and "material push water" operation, the cleanliness of the pipeline is ensured at the beginning of production, thus avoiding problems such as product dilution, contamination or microbial growth. This not only improves the safety and quality stability of the product, but also reduces the risks in the production process. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a juice UHT sterilizer, such as Figure 1-Figure 3 As shown, it includes a UHT sterilization bin 2, one end of the bottom of the UHT sterilization bin 2 is connected to a feed pipe 1, one end of the top of the UHT sterilization bin 2 is connected to a discharge pipe 25, an outer end of the discharge pipe 25 is installed with an electric four-way valve 3, one side output port of the electric four-way valve 3 is connected to a material recovery tank 7 through a recovery pipeline 4, the top output port of the electric four-way valve 3 is connected to a filling pipeline 5, which is used to output and fill materials that meet the requirements, the bottom of the material recovery tank 7 is connected to a discharge pipe 74, a valve 8 and a liquid pump 9 are installed on the discharge pipe 74, and the outer end of the discharge pipe 74 is connected to a re-deployment pipeline 10, which is used to recover materials that do not meet the indicators.

[0022] In this embodiment, the other side output port of the recovery pipeline 4 is connected to a circulation pipeline 6 to facilitate the introduction of cleaning water for circulating cleaning work.

[0023] Specifically, a plurality of horizontal tube groups 23 are arranged inside the UHT sterilization chamber 2, and the ends of the horizontal tube groups 23 are connected in sequence from top to bottom through U-shaped connecting tubes 24, one end of the uppermost horizontal tube group 23 is connected to the discharge pipe 25, and one end of the lowermost horizontal tube group 23 is connected to the feed pipe 1.

[0024] Furthermore, a steam inlet 21 is provided at the bottom of the UHT sterilization chamber 2 to facilitate the entry of steam, and a steam outlet 22 is provided at the top of the UHT sterilization chamber 2 to facilitate the discharge of steam.

[0025] Furthermore, the horizontal pipe group 23 is composed of a plurality of parallel horizontal pipes.

[0026] Furthermore, a stirring motor 72 is installed on the top of the material recovery storage tank 7 , a stirring rod 721 is installed on the bottom output shaft of the stirring motor 72 , and a plurality of stirring blades 722 are installed on the outside of the stirring rod 721 .

[0027] Furthermore, a feed port 73 is provided on one side of the top of the material recovery storage tank 7 , and a feed port 71 is provided on the other side of the top of the material recovery storage tank 7 . The outer end of the feed port 73 is connected to the recovery pipeline 4 .

[0028] When the juice UHT sterilizer of the utility model is used, the juice material to be UHT sterilized first enters the UHT sterilization chamber 2 through the feed pipe 1 for material juice sterilization. In this process, the residual water in the pipeline is pushed by the material to be treated and discharged out of the system, thereby ensuring the cleanliness of the production line and the purity of the product. This step is very important in the UHT sterilization process because it helps prevent problems such as product dilution, contamination or microbial growth caused by residual water in the pipeline. Through the "material push water" operation, it can be ensured that at the beginning of production, the pipeline is filled with pure materials to be processed, rather than residual water that may contain impurities or microorganisms. When the material juice passes through the electric four-way valve 3, the electric four-way valve 3 is adjusted to allow the material to enter the recovery pipeline 4, allowing the material juice with reduced indicators to enter the material recovery storage tank 7 for recovery. After collection, open the valve 8, start the liquid pump 9, and enter the preparation system through the re-dispensing pipeline 10 for use. During the recovery process, until the material index reaches the production index, the side output port of the electric four-way valve 3 can be closed, and the top output port can be opened to allow the material to enter the filling pipeline 5 for filling.
