Abstract
Description
Technical Field
[0001] This utility model relates to the field of sterilization machine technology, and in particular to a steam injection sterilization machine. Background Technology
[0002] An evaporator is a device that evaporates moisture from materials, increasing their concentration. It lowers the boiling point of the material to around 60°C by creating a vacuum, allowing water to evaporate at this temperature. The basic process of a falling film evaporator is as follows: The material enters the heater, which heats it, causing a film to form along the heating tube wall. Partially vaporized steam carries the material down the pipe. The mixture of gas and liquid enters the evaporation chamber. In the evaporation chamber (also called a gas-liquid separator), gas-liquid separation occurs. The gas flows through a pipe above the evaporation chamber to the condenser. The gas is cooled in the condenser, turning back into liquid, which is then discharged by a centrifugal pump. Non-condensable gases are removed by a water ring vacuum pump; the entire system's vacuum environment is also generated by the vacuum pump. The liquid, after gas-liquid separation in the evaporation chamber, becomes the finished product and is pumped out by a centrifugal pump, thus completing the evaporation process.
[0003] Traditional equipment uses direct steam injection without much post-processing, making it difficult to control the concentration of concentrated materials and often resulting in substandard concentrations. Utility Model Content
[0004] The purpose of this invention is to provide a steam injection sterilizer to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A steam injection sterilizer includes a workbench. A steam sterilization module and a concentration pipeline module are fixedly installed on the top of the workbench. The main inlet of the concentration pipeline is connected to the outlet of the steam sterilization module. The steam sterilization module consists of a sterilization reactor, a steam injection system, and inlet / outlet pipes. The inlet / outlet pipes are used for feeding and discharging materials into the sterilization reactor. The steam injection system is used for injecting high-temperature steam into the sterilization reactor. An overflow valve is installed on the top of the sterilization reactor. A filter membrane is installed at the position where the overflow valve communicates with the interior of the sterilization reactor. The filter membrane is used to filter the material so that the material remains inside the sterilization reactor. The concentration pipeline is used to concentrate the material sterilized by the sterilization reactor.
[0007] By adopting the above technical solution, since high-temperature steam needs to be injected during the sterilization process, it is not convenient to control the dilution concentration of the material by the steam. By adding a concentration pipe for material concentration in the subsequent process of the sterilization reactor, the concentration of the material can be controlled, thus realizing the concentration control of the final product and ensuring the quality of the finished product while achieving excellent sterilization effect.
[0008] In a further embodiment, the concentration pipeline comprises multiple sets of overflow devices and heat exchange tubes, with an overflow device provided between each set of heat exchange tubes. The inlet and outlet pipelines include an inlet pipe, a first outlet pipe, a second outlet pipe, a third outlet pipe, and a fourth outlet pipe. Three overflow devices are provided; the first outlet pipe and the second outlet pipe are connected through one overflow device; the second outlet pipe and the third outlet pipe are connected through another overflow device; and the third outlet pipe and the fourth outlet pipe are connected through a third overflow device. The heat exchange tubes are connected and consist of four tubes. The four heat exchange tubes are sleeved on the outside of the first, second, third, and fourth discharge tubes, and the inner diameter of the heat exchange tubes is larger than the outer diameter of the first, second, third, and fourth discharge tubes. Each end of the heat exchange tube is provided with a sealing end cap, and the sealing end cap is provided with a clearance hole to allow the first, second, third, and fourth discharge tubes to pass through. A sealing ring is provided in the clearance hole.
[0009] By adopting the above technical solution, multiple heat exchange tubes heat the first, second, third, and fourth discharge tubes respectively. When the material flows inside the first, second, third, and fourth discharge tubes, it absorbs a large amount of heat energy, which increases its internal entropy. When the material enters the overflow device, the water in the material will turn into steam and overflow from the top of the overflow device, thereby achieving graded concentration of the material and ultimately controlling the concentration and accuracy of the concentration.
[0010] In a further embodiment, the overflow device includes a hollow sealed shell, a one-way valve, and a reverse osmosis membrane. A first connector and a second connector are symmetrically arranged at the bottom end of the sealed shell. Both the first connector and the second connector are in communication with the interior of the sealed shell. The other end of the first connector and the second connector are used to communicate with a first discharge pipe, a second discharge pipe, a third discharge pipe, and a fourth discharge pipe. An exhaust hole is provided at the top of the sealed shell, and an exhaust pipe is provided at the top of the sealed shell. The bottom end of the exhaust pipe is in communication with the exhaust hole. The one-way valve is located inside the exhaust pipe, and the reverse osmosis membrane is located inside the exhaust hole, and the reverse osmosis membrane completely blocks the exhaust hole.
[0011] By adopting the above technical solution, the one-way valve is used to prevent external air and other objects from falling into the interior of the sealed shell and causing material contamination. Because the material accumulates a large amount of heat energy inside the first, second, third, and fourth discharge pipes, when the material enters the interior of the sealed shell, the water contained therein will evaporate quickly and then be discharged from the sealed shell through the reverse osmosis membrane and the one-way valve. The material in the steam will be blocked by the reverse osmosis membrane and remain inside the sealed shell. Because the molecules of the material are large protein molecules, their molecules are much larger than water molecules, so they can be filtered and isolated by the reverse osmosis membrane.
[0012] In a further embodiment, a temperature detection sensor is provided on the outer wall of the overflow device.
[0013] By adopting the above technical solution, the temperature detection sensor is used to detect the surface temperature of the overflow device's outer shell to determine whether the temperature is too high. If the temperature is too high, the reverse osmosis membrane effect will decrease and some of the material will be discharged. Therefore, it is necessary to detect the temperature in real time.
[0014] In a further embodiment, a temperature sensor is provided at the top of the interior of the sterilization reactor, and the temperature sensor is used to detect the temperature at the top of the interior of the sterilization reactor.
[0015] By adopting the above technical solution, the steam temperature required for sterilization is superheated steam. Therefore, it is necessary to determine whether it is necessary to increase the steam injection volume by judging the steam temperature at the inner top of the liquid material surface.
[0016] In a further embodiment, the steam injection system is used to input high-temperature steam into the inner bottom of the sterilization reactor.
[0017] By adopting the above technical solution, more precisely, the distance between the end face of the steam injection system used to inject steam into the sterilization reactor and the lowest point of the inner bottom of the sterilization reactor is between 1 and 1.5 cm, ensuring that the high-temperature steam can be fully effective.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. Because high-temperature steam needs to be injected during the sterilization process, it is not easy to control the dilution concentration of the material by the steam. By adding a concentration pipe for material concentration in the subsequent process of the sterilization reactor, the concentration of the material can be controlled, thus achieving control over the concentration of the final product and ensuring the quality of the finished product while achieving excellent sterilization effect.
