Description
Technical Field
[0001] This utility model relates to the field of camel milk production technology, specifically to a spray sterilization device based on flash evaporation technology. Background Technology
[0002] Sterilization of camel milk is a crucial step, aiming to kill harmful microorganisms in the material, extend the product's shelf life, and ensure its safety and quality stability. Traditional sterilization methods, such as high-temperature long-term sterilization and ultra-high-temperature instantaneous sterilization, while achieving sterilization effects to some extent, have many problems. High-temperature long-term sterilization leads to a significant loss of heat-sensitive nutrients and flavor compounds in the material, affecting the product's nutritional value and taste.
[0003] Existing ultra-high temperature instantaneous sterilization technology mainly consists of a flash chamber, a steam ejector, and a heating device. The flash chamber is a sealed pressure vessel with excellent heat preservation performance. The steam ejector is installed at the top of the flash chamber, with its nozzle facing the inner cavity. The heating device surrounds the outside of the flash chamber and can use electric heating or steam heating to rapidly heat the material inside. When the material enters the flash chamber through a delivery pump, the steam ejector injects high-temperature, high-pressure steam into the flash chamber, mixing with the material's steam flow to further increase the material's temperature and flow rate. Under the high-temperature, high-speed environment, the microbial cells in the material are rapidly killed due to intense thermal shock, shear force, and pressure changes. Flash sterilization is extremely short, generally between a few seconds and tens of seconds, effectively avoiding the loss of nutrients and flavor substances caused by prolonged heating.
[0004] However, the steam injector mentioned above directly sprays steam into the flash chamber, and the steam's own impact force alone is insufficient to quickly and fully contact all the camel milk. Therefore, there is still room for improvement in sterilization efficiency and effectiveness. Utility Model Content
[0005] The purpose of this invention is to provide a spray sterilization device based on flash evaporation technology to solve the above problems, as detailed below.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] This utility model provides a spray sterilization device based on flash evaporation technology, including a flash tank and a steam emitter. A dispersion tube is vertically fixedly connected inside the flash tank for dispersing steam into the flash tank. The steam output end of the steam emitter is connected to the dispersion tube.
[0008] A stirring component is rotatably connected inside the dispersion tube. After steam enters the dispersion tube, it can drive the stirring component to rotate and stir the camel milk.
[0009] The flash evaporator is fixedly connected to a dispersing component, which is used to block the flow of camel milk and increase the disorder of the camel milk flow.
[0010] The aforementioned spray sterilization device based on flash evaporation technology involves injecting camel milk into a flash tank, then injecting high-temperature steam into the flash tank via a steam emitter. The steam is evenly injected into the camel milk through a dispersion tube. When the steam enters the dispersion tube, it can drive the stirring component, causing the stirring component to stir the camel milk and promote its flow. When the flowing camel milk is blocked by the dispersing component, it will change its flow direction, thereby increasing the disorder of the camel milk flow and allowing the high-temperature steam to fully contact the camel milk, thus improving the efficiency of heating the camel milk. The camel milk can be sterilized by heating it for a short time.
[0011] Preferably, the upper end of the dispersion tube passes through the flash tank, and the dispersion tube is sealed to the upper wall of the flash tank. The portion of the dispersion tube inside the flash tank has several through holes.
[0012] Preferably, the stirring assembly includes a rotating shaft, which is rotatably connected inside the dispersion tube and is coaxial with the dispersion tube. An impeller is fixedly connected to the rotating shaft, and the lower end of the rotating shaft passes through the bottom of the dispersion tube and is fixedly connected to a stirring paddle.
[0013] Preferably, the dispersing component includes several vertically arranged annular rings, which are fixedly connected to the flash tank by connecting rods, and the dispersing tube passes through the annular rings.
[0014] Preferably, the annular ring corresponds to the first through hole, and the annular ring is provided with a plurality of second through holes.
[0015] Preferably, the flash tank has several annular grooves on its surface, and a shell for covering the annular grooves is fixedly connected to the surface of the flash tank. A condensate drain pipe is provided at the bottom of the shell, and the top of the flash tank is connected to the shell through a pressure valve.
[0016] Preferably, a discharge valve is fixedly connected to the bottom of the flash tank, and a camel milk injection valve is fixedly connected to the top of the flash tank.
[0017] Preferably, a pressure sensor and a temperature sensor are respectively installed at the top and bottom of the flash tank.
[0018] Preferably, the flash tank, dispersion tube, stirring assembly, and dispersing assembly are all made of stainless steel.
[0019] Preferably, the surface of the housing is provided with heat-insulating material.
[0020] The beneficial effects are:
[0021] High-temperature steam is injected into the flash tank via a steam emitter. The steam is then evenly distributed into the camel milk through a dispersion tube. As the steam enters the dispersion tube, it drives the stirring components, causing the camel milk to agitate and flow. Simultaneously, the flowing camel milk is obstructed by the dispersing components, which changes its flow direction and increases the disorder of the milk flow. This allows the high-temperature steam to fully contact the camel milk, thereby improving the efficiency of heating the camel milk. Compared with existing technologies, this further improves the sterilization efficiency. Attached Figure Description

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0031] See Figures 1-5 As shown, this utility model provides a spray sterilization device based on flash evaporation technology, including a flash tank 1 and a steam emitter 2. A dispersion tube 3 is vertically fixedly connected inside the flash tank 1 to disperse steam into the flash tank 1. The steam output end of the steam emitter 2 is connected to the dispersion tube 3.
[0032] A stirring component 12 is rotatably connected inside the dispersion tube 3. After steam enters the dispersion tube 3, it can drive the stirring component 12 to rotate and stir the camel milk.
[0033] A dispersing component 13 is fixedly connected inside the flash evaporator 1 to block the flow of camel milk and increase the disorder of the camel milk flow.
[0034] As an optional implementation, the upper end of the dispersion tube 3 passes through the flash tank 1, and the dispersion tube 3 is sealed to the upper wall of the flash tank 1. The part of the dispersion tube 3 inside the flash tank 1 is provided with several through holes 11. The steam can be dispersed through the several through holes 11 so that the steam can fully contact the camel milk.
[0035] The stirring assembly 12 includes a rotating shaft 15, which is rotatably connected inside the dispersion tube 3 and is coaxial with the dispersion tube 3. An impeller 16 is fixedly connected to the rotating shaft 15, and the lower end of the rotating shaft 15 passes through the bottom of the dispersion tube 3 and is fixedly connected to a stirring paddle 14.
[0036] After the steam enters the dispersion tube 3, it can drive the impeller 16 to rotate. The impeller 16 can drive the stirring paddle 14 to rotate through the rotating shaft 15. The stirring paddle 14 stirs the camel milk, causing the camel milk to flow in the flash tank 1.
[0037] The dispersing component 13 includes several vertically arranged annular rings 17. The annular rings 17 are fixedly connected to the flash tank 1 by connecting rods 18. The dispersing tube 3 passes through the annular rings 17. The annular rings 17 correspond to the through holes 11, and several through holes 19 are provided on the annular rings 17. When the flowing camel milk encounters the obstruction of the annular rings 17, it will change its flow direction. A portion of the camel milk will pass through the through holes 11 and collide with the inner wall of the flash tank 1, so that the camel milk can be fully tumbled in the flash tank 1.
[0038] The surface of the flash evaporator 1 has several annular grooves 10. A shell 4 for covering the annular grooves 10 is fixedly connected to the surface of the flash evaporator 1. A condensate drain pipe is provided at the bottom of the shell 4. The top of the flash evaporator 1 is connected to the shell 4 through a pressure valve 5. The annular grooves 10 can increase the heating area of the flash evaporator 1. After the camel milk is heated, the high-temperature water vapor in the flash evaporator 1 is first discharged into the shell 4 through the pressure valve 5. This heat can be used to increase the surface temperature of the flash evaporator 1, which is beneficial for heating the camel milk at a uniform speed.
[0039] In addition, when the steam emitter 2 injects high-temperature steam into the flash tank 1, the pressure valve 5 can also be opened to introduce some steam into the shell 4 to preheat the outside of the flash tank 1.
[0040] A discharge valve 8 is fixedly connected to the bottom of the flash tank 1, and a camel milk injection valve 6 is fixedly connected to the top of the flash tank 1. The injection valve 6 is a one-way pressure valve. In addition, a flow sensor is installed in the injection valve 6 to monitor the amount of camel milk injected into the flash tank 1. The flash tank 1 must not be filled with camel milk, and space must be left for steam injection.
[0041] A pressure sensor 7 and a temperature sensor 9 are respectively installed at the top and bottom of the flash tank 1.
[0042] The flash tank 1, dispersion tube 3, stirring assembly 12, and dispersing assembly 13 are all made of stainless steel.
[0043] The surface of the housing 4 is provided with heat insulation material, which can be an insulated surface to prevent heat loss and improve the thermal efficiency of the device.
[0044] Using the above structure, camel milk is injected into flash tank 1, and then high-temperature steam is injected into flash tank 1 through steam emitter 2. The steam is evenly injected into the camel milk through dispersion tube 3. When the steam enters dispersion tube 3, it can push stirring component 12 to stir the camel milk and promote its flow. When the flowing camel milk is blocked by dispersing component 13, it will change its flow direction, thereby increasing the disorder of the camel milk flow and allowing the high-temperature steam to fully contact the camel milk, thereby improving the efficiency of heating the camel milk. The camel milk can be sterilized by heating it for a short time.
[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
