Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Embodiment 1
[0023] Please refer to Figures 1-4The purpose of the embodiment is to provide a sterilization homogenization enzyme-killing system suitable for replacing the raw material of lamb milk, which comprises a sterilization machine 1, the sterilization machine 1 comprises a sterilization tank 11, a high-temperature box 13 is fixedly arranged inside the sterilization tank 11 near the top end, an electric heater is fixedly installed on the bottom surface in the high-temperature box 13, the inside of the sterilization tank 11 and the high-temperature box 13 is filled with pure water for heat conduction, the high-temperature box 13 is immersed in the pure water in the sterilization tank 11, when the electric heater heats the pure water in the high-temperature box 13, the pure water heats the high-temperature box 13 through heat exchange between the high-temperature box 13 and the tank body, the high-temperature box 13 heats the pure water in the sterilization tank 11 through heat exchange, because hot water will float on the upper layer of cold water, therefore the temperature of the upper layer water near the high-temperature box 13 in the sterilization tank 11 will be higher than that of the lower layer water, a homogenizer 2 is arranged on one side of the sterilization tank 11, a preheating pipe 12 is fixedly connected inside the sterilization tank 11 near the bottom end, one end of the preheating pipe 12 penetrates through the lower side wall of the sterilization tank 11 and is fixedly installed with a feeding pump, the input port of the feeding pump is in communication with a pipeline for conveying materials, when the feeding pump conveys the materials into the inside of the preheating pipe 12, the materials will flow through the section of the preheating pipe 12 inside the sterilization tank 11, at this time the pure water in the sterilization tank 11 will heat the pipe wall of the preheating pipe 12 through heat exchange, the pipe wall of the preheating pipe 12 heats the materials inside through heat exchange, so that the temperature of the materials rises to about 72 degrees, through heating the materials, the molecular motion of the materials is intensified and the average molecular distance is increased, so that the materials flow more easily, thereby reducing the viscosity of the materials, the other end of the preheating pipe 12 penetrates through one side of the sterilization tank 11 and is fixedly arranged on the input port of the homogenizer 2, when the preheating pipe 12 conveys the heated materials into the inside of the homogenizer 2, the homogenizer 2 homogenizes the materials, because the heated materials have low viscosity in the homogenizer 2, the materials are not easy to adhere to the rotor and stator in the homogenizer 2, so that the rotor and stator in the homogenizer 2 can sufficiently shear and emulsify the materials, thereby improving the homogenization effect of the homogenizer 2 on the materials.
[0024] The heat exchange pipe 14 is arranged in the interior of the sterilization tank 11 and in the interior of the high-temperature box 13. The output port of the homogenizer 2 is fixedly connected with a feeding pipe 21. One end of the feeding pipe 21 penetrates the side wall of the sterilization tank 11 and is fixedly connected with the end of the heat exchange pipe 14 away from the outer shell 41. The feeding pipe 21 penetrates the upper side wall of the high-temperature box 13. After the homogenized material is input into the heat exchange pipe 14 through the feeding pipe 21, the material in the heat exchange pipe 14 is heated by the heat exchange pipe 14 wall through heat exchange with the pure water in the high-temperature box 13. The temperature of the material is heated to about 85 degrees by the heat exchange pipe 14 wall. The steam heating mechanism 4 is arranged on the upper side of the sterilization machine 1. One end of the heat exchange pipe 14 penetrates the top of the sterilization tank 11 and is connected with the steam heating mechanism 4. When the material flows into the steam heating mechanism 4 from the heat exchange pipe 14, the steam heating mechanism 4 further heats the material to about 105 degrees by spraying high-temperature steam into the material. The material is sterilized and enzyme is killed by the high temperature. The parallel holding pipe 3 is arranged on the side of the steam heating mechanism 4 away from the heat exchange pipe 14. The parallel holding pipe 3 is a long-stroke serpentine heat preservation pipe. The other end of the parallel holding pipe 3 is provided with a discharging assembly. The high-temperature material takes a long time to flow into the discharging assembly from the parallel holding pipe 3 after the steam heating mechanism 4 delivers the heated material to the parallel holding pipe 3. The material in the parallel holding pipe 3 is heat preserved in this time period, and the material is kept at a high temperature for a long time, so that the material is fully sterilized and enzyme is killed, and the quality of the material is improved.
[0025] The structure of the steam heating mechanism 4 is refined as follows. Figure 3 and Figure 4The steam heating mechanism 4 comprises an outer shell 41 fixedly installed at one end of the heat exchange pipe 14, a Venturi tube 42 fixedly installed inside the outer shell 41, the internal passage of the Venturi tube 42 being of a structure with thick ends and a thin middle, a parallel holding tube 3 fixedly connected to the other end of the Venturi tube 42, the Venturi tube 42 being in communication with the heat exchange pipe 14 and the parallel holding tube 3, a plurality of feeding holes 421 being transversely arrayed on the Venturi tube 42 near the parallel holding tube 3, a one-way valve 422 being fixedly installed inside each feeding hole 421, the flow direction of the one-way valve 422 being from the outer shell 41 to the Venturi tube 42, that is, the one-way valve 422 only allows steam to enter the Venturi tube 42 and does not allow the material in the Venturi tube 42 to leak out through the feeding holes 421, a steam inlet pipe 43 being fixedly connected to the top of the outer shell 41 for conveying steam into the outer shell 41, when the material enters the Venturi tube 42 from the heat exchange pipe 14, when the material passes through the narrowest part of the passage of the Venturi tube 42, the flow rate of the material rapidly increases due to the sudden reduction of the cross-sectional area of the passage of the Venturi tube 42, thereby forming a low-pressure area, when high-temperature steam is injected into the outer shell 41 through the steam inlet pipe 43, the high-temperature steam enters the Venturi tube 42 through the one-way valve 422 to supplement the low-pressure area, in this process, the high-temperature steam fully contacts the material in the Venturi tube 42, the heat in the high-temperature steam heats the material through heat exchange, at the same time, the high-temperature steam increases the pressure inside the Venturi tube 42, thereby increasing the boiling point temperature of the material, so that the material can be heated to a high temperature of 105 degrees Celsius, thereby fully sterilizing and deactivating the enzymes of the material, compared with the traditional indirect heat exchange, the use of this steam direct heat exchange to heat the material can effectively improve the thermal efficiency, and the mixture of the high-temperature steam and the material is in a stable solution state, the material is not easy to scale on the inner wall of the Venturi tube 42, so that the Venturi tube 42 will not be blocked, so that the system can be stably operated for a long time.
[0026] At the same time, the steam heating mechanism 4 further comprises an electric regulating valve 44 and a steam valve 45 fixedly connected to the steam inlet pipe 43, the steam valve 45 being arranged on the side of the electric regulating valve 44 away from the outer shell 41, a communication pipe 46 being fixedly connected between the electric regulating valve 44 and the parallel holding tube 3, an adjuster 47 being fixedly connected to the communication pipe 46, the adjuster 47 being capable of adjusting the steam pressure in the communication pipe 46, when the steam flow rate conveyed by the steam inlet pipe 43 into the Venturi tube 42 is too large, causing the pressure in the Venturi tube 42 and the parallel holding tube 3 to be too large, the excess steam in the parallel holding tube 3 will flow back to the electric regulating valve 44 through the communication pipe 46, the adjuster 47 and the electric regulating valve 44 can adjust the steam flow rate in the steam inlet pipe 43 according to the amount of steam flowing back in the communication pipe 46, so that the steam inlet pipe 43 can always convey an appropriate amount of high-temperature steam into the Venturi tube 42, avoiding the situation that the pressure in the Venturi tube 42 and the parallel holding tube 3 is too large, thereby causing a safety hazard.
[0027] The structure of the discharging assembly is detailed as follows: the cooling pipe 31 is arranged inside the sterilizing tank 11, one end of the parallel holding pipe 3 penetrates the top wall of the sterilizing tank 11 and is connected with one end of the cooling pipe 31, the other end of the cooling pipe 31 penetrates the position close to the bottom end of the sterilizing tank 11 and is fixedly connected with the discharging pipe 32, the other end of the discharging pipe 32 is fixedly installed with the back pressure valve 33, the back pressure valve 33 is used for adjusting the pressure in the discharging pipe 32, the three-way plug valve 34 is fixedly installed on the side wall of the discharging pipe 32 close to the position of the back pressure valve 33, the cooling pipe 31 is arranged longitudinally in the sterilizing tank 11, because the temperature of the pure water in the sterilizing tank 11 gradually decreases from top to bottom, the heating capacity of the pure water with different temperatures on the pipe wall of the cooling pipe 31 is different, therefore, the temperature of the pipe wall of the cooling pipe 31 gradually decreases from top to bottom, when the high-temperature material enters into the cooling pipe 31 from the parallel holding pipe 3, because the temperature of the material is higher than the temperature of the pipe wall of the cooling pipe 31, the material will heat the pipe wall of the cooling pipe 31 through heat exchange, in this process, the material will be cooled due to heat loss, when the material enters into the discharging pipe 32 from the cooling pipe 31, the temperature of the material will be reduced to the storage temperature without losing nutrients, at this time, the back pressure valve 33 adjusts the pressure in the discharging pipe 32, so that the material flows out stably through the output port of the three-way plug valve 34, and the safe discharging of the material is realized.

It should be understood by the person skilled in the art that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and the description in the specification are only preferred examples of the utility model and are not used to limit the utility model, various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
