Description

Technical Field

[0001] This invention relates to the field of material sterilization technology, and in particular to a continuous high-temperature instantaneous sterilization system. Background Technology

[0002] Sterilization systems play a vital role in the food industry, and with the continuous development of the industry, the demand for food sterilization is increasing. Effective sterilization can extend the shelf life of food, ensure food safety, and meet consumers' requirements for health and quality, playing a key role in the stable development of the food industry and market supply. In recent years, the scale of food processing has gradually expanded, placing higher demands on the efficiency and stability of sterilization systems.

[0003] In the traditional food sterilization field, intermittent sterilization is a commonly used method. The specific operation involves placing materials in batches into the sterilization equipment and sequentially completing a full cycle of "heating-holding-cooling," after which the materials are removed. Then, the next batch of materials needs to undergo the same process. This method is widely used in the sterilization process of various foods, whether solid or liquid. When more efficient sterilization methods are lacking, intermittent sterilization has become a standard choice to meet basic sterilization needs.

[0004] However, this intermittent sterilization method has significant drawbacks. Because each batch needs to independently complete the full "heating-holding-cooling" cycle, and subsequent batches must repeat the process, the overall sterilization efficiency is low. Furthermore, during the operation, slight variations in equipment operation or human error can easily lead to quality fluctuations between different batches, making it impossible to guarantee consistent sterilization effects and quality across all batches. Summary of the Invention

[0005] This application provides a continuous high-temperature instantaneous sterilization system, which adopts continuous high-temperature instantaneous sterilization to improve sterilization efficiency and ensure the consistency of food quality.

[0006] This application provides a continuous high-temperature instantaneous sterilization system, which adopts the following technical solution: A continuous high-temperature instantaneous sterilization system includes a feeding mechanism. A heating and sterilization mechanism is provided on one side of the feeding mechanism. The heating and sterilization mechanism includes a steam generator and a heating and sterilization pipe. The steam generator is connected to the heating and sterilization pipe through a pipeline. A first high-pressure blower is provided between the feeding mechanism and the heating and sterilization mechanism. The first high-pressure blower is used to provide power for conveying raw materials. High-temperature airflow is formed by mixing steam with air drawn in by the high-pressure blower to achieve high-temperature sterilization. A separation device is provided at the end of the heating and sterilization mechanism away from the feeding mechanism. A steam discharge device and a cooling device are respectively provided on both sides of the separation device. A recovery device is provided at the end of the cooling device away from the separation device.

[0007] By adopting the above technical solution, the present invention designs a continuous high-temperature instantaneous sterilization system. In use, raw materials are added through a feeding mechanism. After addition, the raw materials are transported by a first high-pressure blower. After the raw materials enter the heating sterilization tube, the steam generated by the steam generator mixes with the air drawn in by the high-pressure blower to form a high-temperature airflow, thereby sterilizing the raw materials in the heating sterilization tube at high temperature. After high-temperature sterilization, the raw materials enter a separation device to separate the raw materials and the steam in the raw materials. The steam enters a steam discharge device to exchange heat with cooling water and is discharged as discharge water. The raw materials enter a cooling device for cooling and are collected after cooling. In summary, this system can achieve continuous high-temperature instantaneous sterilization, avoiding the problems of low efficiency and easy quality fluctuations of intermittent sterilization. It uses the mixture of steam and air drawn in by the high-pressure blower to form a high-temperature airflow for high-temperature sterilization, and can simultaneously separate steam, cool materials, and recover products.

[0008] Preferably, the feeding mechanism includes a feeder, which is located at the inlet of the heating and sterilization mechanism. The feeder is provided with an HRV raw material inlet for adding raw materials, and the product raw materials are added through the HRV raw material inlet.

[0009] By adopting the above technical solution, the feeder is installed at the inlet of the heating and sterilization tube during use. At the same time, the feeder is equipped with an HRV raw material inlet to facilitate the addition of raw materials, so that the raw materials can smoothly enter the continuous high temperature instantaneous sterilization system.

[0010] Preferably, an auxiliary heating tube is provided on the outside of the heating and sterilization tube, which is used to keep the heating and sterilization tube warm.

[0011] By adopting the above technical solution, during use, the auxiliary heating tube is installed on the outer wall of the heating and sterilization tube. The auxiliary heating tube insulates the heating and sterilization tube, maintaining a high-temperature environment inside the heating and sterilization tube and ensuring the effect of high-temperature sterilization.

[0012] Preferably, the separation device includes a first cyclone separator, which is installed at the end of the heating and sterilization tube away from the feeder, and is used to separate the moisture in the raw material into steam.

[0013] By adopting the above technical solution, when in use, the first cyclone separator is installed at the end of the heating sterilization tube. The first cyclone separator can separate the moisture in the raw material into steam, which facilitates subsequent steam discharge and cooling operations, improves sterilization efficiency, and avoids the problems of low efficiency and quality fluctuations in intermittent sterilization.

[0014] Preferably, the steam discharge device includes a heat exchanger installed on the side of the first cyclone separator away from the heating and sterilization tube. The heat exchanger exchanges heat between the steam separated from the raw material and the cooling water, and discharges it through a drain outlet.

The heat exchanger is used to exchange heat between the steam separated from the raw material and the cooling water and then discharge it, which can achieve effective heat treatment and avoid energy waste and environmental impact caused by direct steam discharge.

[0016] Preferably, a pressure detection device is also provided on the connecting pipeline between the separation device and the steam discharge device, and the pressure detection device is used to control the inlet pressure of the first cyclone separator.

[0017] By adopting the above technical solution, the pressure detection device can ensure that the first cyclone separator operates under stable pressure conditions during use, avoiding poor separation effect due to pressure fluctuations, thereby ensuring the stable operation of the entire sterilization system and the consistency of sterilization effect.

[0019] By adopting the above technical solution, the cooling pipe is installed on the outer wall of the connecting pipe during use. The cooling water in the cooling pipe is used to cool the raw materials in the connecting pipe, which can quickly cool down the raw materials that have been sterilized at high temperature, avoid the adverse effects of high temperature on the quality of the raw materials, and this cooling method can ensure the uniformity of raw material cooling.

[0020] Preferably, the recovery device includes a buffer tank and an equipment box. The buffer tank is used to buffer the cooled raw material and transport it to the equipment box. A second cyclone separator is provided on the top of the buffer tank. The second cyclone separator is connected to the connecting pipe and further separates the steam in the raw material and discharges it to the outside.

[0021] By adopting the above technical solution, during use, the second cyclone separator is used to separate the gas and solid components of the material, further separating the steam in the material to prevent residual moisture from remaining in the material. Then, the material is stably transported to the buffer tank for subsequent processing. At the same time, the equipment box can store and manage the material, improving the operational stability of the entire sterilization system and the orderly handling of materials.

[0022] Preferably, a second high-pressure blower is also connected to the connecting pipe. The second high-pressure blower is installed on one side of the first cyclone separator and is interconnected with the first high-pressure blower through a pipeline.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] This invention discloses a continuous high-temperature instantaneous sterilization system, such as... Figure 1 As shown, the system includes a feeding mechanism 1, a heating and sterilization mechanism 2, a first high-pressure blower 3, a separation device 4, a steam emission device 5, a cooling device 6, and a recovery device 7. The heating and sterilization mechanism 2 is located on one side of the feeding mechanism 1. The first high-pressure blower 3 is located between the feeding mechanism 1 and the heating and sterilization mechanism 2. The separation device 4 is located at the end of the heating and sterilization mechanism 2 furthest from the feeding mechanism 1. The steam emission device 5 and the cooling device 6 are located on opposite sides of the separation device 4. The recovery device 7 is located at the end of the cooling device 6 furthest from the separation device 4. This system achieves continuous high-temperature instantaneous sterilization, improving sterilization efficiency and ensuring stable food quality. This is because the system enables continuous material conveying and sterilization, avoiding the inefficiency and quality fluctuations associated with intermittent batch sterilization operations.

[0030] Specifically, the feeding mechanism 1 includes a feeder 11, which is located at the inlet end of the heating sterilization tube 22. The feeder 11 has an HRV (High-Voltage Ratio) feed inlet for adding raw materials. The feeder 11 can be a screw feeder 11, which transports the raw materials into the heating sterilization tube 22 through the rotation of its helical blades. Its material is typically stainless steel, which has good corrosion resistance. The HRV feed inlet can be funnel-shaped for easy material addition. Alternatively, a vibrating feeder 11 can be used as a replaceable feature of the feeder 11. The vibrating feeder 11 uses vibration to ensure the raw materials enter the heating sterilization tube 22 evenly. The feeder 11 and the HRV feed inlet are connected by welding or bolts to ensure a tight and stable connection. The combination logic of the feeder 11 and the HRV feed inlet is that the HRV feed inlet adds the raw materials to the feeder 11, and the feeder 11 transports the raw materials to the heating sterilization tube 22, achieving a continuous supply of raw materials.

[0031] The heating and sterilization mechanism 2 includes a steam generator 21 and a heating and sterilization pipe 22. The steam generator 21 is connected to the heating and sterilization pipe 22 via a pipeline. The steam generator 21 can be an electrically heated steam generator 21, which heats water into steam using electrical energy. Its outer shell is typically made of carbon steel, and it contains components such as heating tubes. The heating and sterilization pipe 22 can be a stainless steel pipe, which has good thermal conductivity and corrosion resistance. The connecting pipe 10 between the steam generator 21 and the heating and sterilization pipe 22 can be made of high-temperature resistant rubber or metal tubing. Alternatively, a gas-fired steam generator 21 can be used as an alternative feature, which uses the heat generated by the combustion of gas to heat water into steam. The steam generated by the steam generator 21 is transported to the heating and sterilization pipe 22 through the pipeline, where it mixes with the air drawn in by the first high-pressure blower 3 to form a high-temperature airflow, which sterilizes the raw materials at high temperature.

[0032] The first high-pressure blower 3 provides power for conveying raw materials. It utilizes the mixture of steam and air drawn into the blower to form a high-temperature airflow, achieving high-temperature sterilization. The first high-pressure blower 3 can be a centrifugal blower, which generates high-pressure airflow through the rotation of its impeller. Its outer casing is typically made of cast iron, and it contains components such as an impeller and a motor. The motor drives the impeller to rotate at high speed, drawing in and pressurizing air before delivering it to the heating and sterilization tube 22. Alternatively, an axial-flow high-pressure blower can be used as an alternative feature to the first high-pressure blower 3, generating high-pressure airflow through the rotation of an axial-flow impeller. The first high-pressure blower 3 is connected to the feeding mechanism 1 and the heating and sterilization mechanism 2 via pipelines to ensure smooth airflow delivery. The power provided by the first high-pressure blower 3 enables the raw materials to be continuously conveyed from the feeding mechanism 1 to the heating and sterilization mechanism 2, simultaneously mixing with steam to form a high-temperature airflow for high-temperature sterilization.

[0033] The separation device 4 includes a first cyclone separator 41, which is installed at the end of the heating and sterilization tube 22 away from the feeder 11. The first cyclone separator 41 is used to separate the moisture in the raw material into steam. The main body of the first cyclone separator 41 is usually cylindrical, made of carbon steel or stainless steel, and contains components such as spiral blades. After the raw material enters the first cyclone separator 41, the moisture is separated and forms steam under the action of centrifugal force. The first cyclone separator 41 is connected to the heating and sterilization tube 22 by a flange for easy installation and disassembly. The first cyclone separator 41 separates the moisture from the raw material after high-temperature sterilization, preparing for subsequent steam discharge and cooling treatment.

[0034] The steam discharge device 5 includes a heat exchanger 51, which is installed on the side of the first cyclone separator 41 away from the heating and sterilization tube 22. The heat exchanger 51 exchanges heat between the steam separated from the raw material and the cooling water, and then discharges the steam through a drain port. The heat exchanger 51 can be a plate heat exchanger, which consists of multiple metal plates, and the heat exchange between the steam and the cooling water is achieved through the channels between the plates. The material of the heat exchanger 51 is usually stainless steel, which has good thermal conductivity and corrosion resistance. The drain port can be pipe-shaped and connected to the drainage system. Alternatively, a shell-and-tube heat exchanger 51 can be used as an alternative feature of the heat exchanger 51, which achieves heat exchange through tube bundles and a shell. The heat exchanger 51 is connected to the first cyclone separator 41 through a pipe. Steam enters the heat exchanger 51 and exchanges heat with the cooling water, transferring the heat in the steam to the cooling water, and then the condensate is discharged through the drain port, realizing the discharge of steam and the recovery and utilization of heat.

[0035] The cooling device 6 includes a cooling pipe 61 installed outside the connecting pipe 10, with an inlet for adding cooling water. The cooling pipe 61 can be a spiral copper pipe with good thermal conductivity. The inlet of the cooling pipe 61 can be a circular interface for easy addition of cooling water. Alternatively, a square cooling pipe 61 can be used as an alternative, as it has a larger heat dissipation area. The cooling pipe 61 is connected to the connecting pipe 10 by welding or clamping to ensure effective cooling. The cooling water in the cooling pipe 61 absorbs heat from the raw material in the connecting pipe 10, rapidly cooling the material.

[0036] The recovery device 7 includes a buffer tank 71 and an equipment box 72. The buffer tank 71 buffers the cooled raw material and transports it to the equipment box 72. A second cyclone separator 12 is installed on the top of the buffer tank 71 and is connected to the connecting pipe 10. The second cyclone separator 12 further separates the vapor from the raw material and discharges it to the outside. The buffer tank 71 can be a rubber tube with a certain degree of elasticity to buffer the impact force of the raw material. The equipment box 72 can be a plastic box or a metal box for storing the raw material after sterilization and cooling. The structure of the second cyclone separator 12 is similar to that of the first cyclone separator 41. A gravity separator can also be used as an alternative feature of the second cyclone separator 12, which separates the vapor from the raw material by gravity. The buffer tank 71 is connected to the equipment box 72 and the second cyclone separator 12 through a pipeline. The buffer tank 71 transports the cooled raw material to the equipment box 72, and the second cyclone separator 12 further separates the vapor from the raw material to ensure the quality of the recovered raw material.

[0037] The implementation principle of this embodiment is as follows: The continuous high-temperature instantaneous sterilization system continuously supplies raw materials through the feeding mechanism 1. The first high-pressure blower 3 provides power to transport the raw materials to the heating and sterilization mechanism 2. The heating and sterilization mechanism 2 uses a high-temperature airflow formed by mixing steam and air to sterilize the raw materials at high temperature. The separation device 4 separates the moisture from the raw materials, the steam emission device 5 discharges steam and recovers heat, the cooling device 6 cools the raw materials, and the recovery device 7 buffers and recovers the cooled raw materials. The entire system realizes continuous material transportation and sterilization, avoids the defects of intermittent sterilization, improves sterilization efficiency, ensures the stability of food quality, and has significant improvements and contributions to existing technologies.

[0038] Example 2 The difference between this embodiment and the previous embodiment is that a pressure detection device 9 is also provided on the connecting pipe 10 between the separation device 4 and the steam discharge device 5. The pressure detection device 9 is used to control the inlet pressure of the first cyclone separator 41. The pressure detection device 9 can be a pressure sensor, which detects the pressure on the connecting pipe 10 and converts the pressure signal into an electrical signal. The pressure sensor typically consists of a pressure-sensitive element and a signal processing circuit, and is installed on the connecting pipe 10. Alternatively, a pressure switch can be used as a replacement feature of the pressure detection device 9, automatically opening or closing when the pressure reaches a set value. The pressure detection device 9 is connected to the first cyclone separator 41 via a signal line to monitor and control the inlet pressure of the first cyclone separator 41 in real time.

[0039] The implementation principle of this embodiment is as follows: the pressure detection device 9 monitors the pressure on the connecting pipe 10 between the separation device 4 and the steam emission device 5 in real time. By controlling the inlet pressure of the first cyclone separator 41, the normal operation of the separation device 4 is ensured, the steam emission is made more stable, and the reliability and stability of the entire system are improved. This optimizes and improves the existing technology.
