Description

Technical Field

[0001] This utility model relates to the technical field of yeast production and processing equipment, and in particular to a high-efficiency and energy-saving high-protein yeast extract high-temperature dissolution and sterilization system. Background Technology

[0002] Existing high-temperature sterilization devices, such as Figure 1 As shown, a heat exchanger for sterilization is provided, which includes two modules: a steam heating module and a cooling module. The steam heating module uses coils to heat the material with steam, and the heated material is cooled by coils in the cooling module to complete high-temperature sterilization. This sterilization device has the following problems during use:

[0003] 1. The production of yeast extract has high steam energy consumption and large cooling water consumption;

[0004] 2. Using steam for rapid, linear heating can cause denaturation of certain proteins, clogging internal pipes and reducing production efficiency.

[0005] 3. Low level of automation control. Utility Model Content

[0006] This invention provides a high-efficiency and energy-saving high-protein yeast extract high-temperature dissolution and sterilization system, which aims to solve the problems of high steam energy consumption, large cooling water consumption, rapid denaturation of special proteins causing blockage of internal pipes due to rapid heating leading to decreased production efficiency, and low level of automation control in the existing sterilization devices.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A high-efficiency and energy-saving high-protein yeast extract high-temperature dissolution and sterilization system includes a heat exchanger for high-temperature dissolution and sterilization, wherein the heat exchanger is respectively equipped with a material heat energy recovery module, a steam condensate heat energy recovery module, a steam heating module and a cooling module;

[0009] The initial material enters the material heat recovery module and exchanges heat with the fourth material to form the secondary material. The cooled fourth material forms the fifth material and enters the cooling module.

[0010] Secondary materials enter the steam condensate heat recovery module and exchange heat with the steam condensate to form tertiary materials. The cooled steam condensate is discharged from the heat exchanger.

[0011] The tertiary material enters the steam heating module and exchanges heat with high-temperature steam to form the quaternary material. After the high-temperature steam cools down, it forms steam condensate, which enters the steam condensate heat energy recovery module. The quaternary material enters the material heat energy recovery module.

[0012] After the material enters the cooling module five times and exchanges heat with the cooling water, it forms a sixth material discharge heat exchanger, and the heated cooling water is discharged from the heat exchanger.

[0013] Preferably, the material heat recovery module, the steam condensate heat recovery module, the steam heating module, and the cooling module are all coil heat exchange structures.

[0014] More preferably, the material heat recovery module, the steam condensate heat recovery module, the steam heating module, and the cooling module are all housed separately within the same heat exchanger.

[0015] Furthermore, the initial material temperature of the material heat recovery module does not exceed 65°C, and the temperature of the secondary material is at least 85°C.

[0016] Furthermore, the temperature of the tertiary materials formed by the steam condensate heat recovery module is at least 95°C, and the temperature of the steam condensate entering the steam condensate heat recovery module is 100~135°C.

[0017] Preferably, the temperature of the four materials generated by the steam heating module is 120~130℃.

[0018] More preferably, the temperature of the six materials at the outlet of the cooling module is 75~85°C.

[0019] Furthermore, a thermometer is installed at the outlet of the material coil of the steam heating module. The sensing end of the thermometer monitors the temperature of the generated five-stage material. A steam regulating valve is installed on the high-temperature steam feed pipe of the material in the steam heating module. The steam regulating valve is linked with the thermometer measuring the temperature of the five-stage material through the plant's control system.

[0020] Furthermore, the high-temperature steam feed pipe is also equipped with a steam pneumatic switch valve and a pressure gauge.

[0021] Furthermore, a thermometer is installed at the outlet of the material coil of the cooling module. The sensing end of the thermometer monitors the temperature of the generated six materials. A cooling water regulating valve is installed on the cooling water inlet pipe. The control system of the cooling water regulating valve is linked with the thermometer that measures the temperature of the six materials.

[0022] The beneficial effects of this utility model are:

[0023] 1. Set up a material heat recovery module. The initial material is preheated to form secondary material, which saves the steam consumption of the steam heating module. The quinary material formed after cooling saves the cooling water consumption of the cooling module.

[0024] 2. A steam condensate heat energy recovery module is set up so that secondary materials are preheated to form tertiary materials, saving steam consumption of the steam heating module and reducing heat energy waste of steam condensate.

[0025] 3. Through primary and secondary preheating, a multi-stage stepped heating is formed before steam heating, avoiding single-stage rapid heating, reducing the amount of protein denaturation and precipitation, and effectively dissolving the special proteins that have been precipitated before the material enters, solving the problem of pipeline blockage and improving efficiency.

[0026] 4. The addition of a steam regulating valve and an electronic thermometer after steam heating improves the automation level of steam heating and saves steam consumption through refined control; the addition of a cooling water regulating valve and an electronic thermometer after cooling water cooling improves the automation level of cooling and saves cooling water consumption through refined control.

[0030] The embodiments will be further described below with reference to the accompanying drawings.

[0031] like Figure 2 and Figure 3 As shown in the preferred embodiment 1, a high-efficiency and energy-saving high-protein yeast extract high-temperature dissolution and sterilization system includes a heat exchanger for high-temperature dissolution and sterilization, wherein the heat exchanger is respectively provided with a material heat energy recovery module 1, a steam condensate heat energy recovery module 2, a steam heating module 3 and a cooling module 4.

[0032] The initial material enters the material heat recovery module 1 and exchanges heat with the fourth material to form the secondary material. The cooled fourth material forms the fifth material and enters the cooling module 4.

[0033] Secondary materials enter the steam condensate heat recovery module 2 and exchange heat with the steam condensate to form tertiary materials. The cooled steam condensate is discharged from the heat exchanger.

[0034] The tertiary material enters the steam heating module 3 and exchanges heat with high-temperature steam to form the quaternary material. After the high-temperature steam cools down, it forms steam condensate and enters the steam condensate heat energy recovery module 2. The quaternary material enters the material heat energy recovery module 1.

[0035] After the material enters the cooling module 4 five times and exchanges heat with the cooling water, it forms a sixth material discharge heat exchanger, and the heated cooling water is discharged from the heat exchanger.

[0036] This patent adds a material heat recovery module 1 and a steam condensate heat recovery module 2 to the heat exchanger used in existing high-temperature sterilization devices. The newly added material heat recovery module 1 (i.e....) Figure 2 The first section of the coil group from the right in the middle exchanges heat with the four materials heated by steam. The initial material is preheated to form the secondary material, saving the steam consumption of the steam heating module 3.

[0037] The heat energy of the fourth-stage material is recovered for preheating. After cooling, the fourth-stage material becomes the fifth-stage material, which then passes through cooling module 4 (i.e., Figure 2 The cooling water of the fourth section of the coil group from the right in the middle is cooled down to form six material discharges, and the five material discharges formed after cooling down save the cooling water consumption of the cooling module 4.

[0038] Secondary materials enter the steam condensate heat recovery module 2 (i.e. Figure 2 The second section of the coil group from the right in the middle exchanges heat with the high-temperature steam condensate, and the secondary material is thus preheated to form the tertiary material, saving the steam consumption of the steam heating module 3 and reducing the heat energy waste of the steam condensate.

[0039] The initial material undergoes primary preheating and secondary preheating in sequence during the process from initial material to tertiary material. This multi-stage stepped heating before steam heating avoids rapid heating in a single stage, reduces the amount of protein denaturation and precipitation, and can also effectively dissolve any precipitated special proteins attached to the material before it enters, solving the problem of pipeline blockage and improving efficiency.

[0040] In a preferred embodiment 2, the material heat recovery module 1, the steam condensate heat recovery module 2, the steam heating module 3, and the cooling module 4 are all coil heat exchange structures. The added structure is almost identical to the original heat exchanger, facilitating installation and layout.

[0041] The material heat recovery module 1 is a heat exchange coil group formed by the initial material coil and the fourth material coil. The feed end of the initial material coil is connected to the material inlet pipe, and the discharge end of the fourth material coil is connected to the feed end of the fifth material coil through the connecting pipe.

[0042] The steam condensate heat recovery module 2 is a heat exchange coil group formed by a steam condensate coil and a secondary material coil. The feed end of the secondary material coil is connected to the discharge end of the initial material coil through a connecting pipe, and the discharge end of the steam condensate coil is connected to the steam condensate discharge pipe outside the heat exchanger.

[0043] The steam heating module 3 is a coil group formed by a tertiary material coil and a steam coil. The feed end of the steam coil is connected to the steam inlet pipe outside the heat exchanger, and the discharge end of the steam coil is connected to the feed end of the steam condensate coil through a connecting pipe. The feed end of the tertiary material coil is connected to the discharge end of the secondary material coil through a connecting pipe, and the discharge end of the tertiary material coil is connected to the feed end of the quaternary material coil through a connecting pipe.

[0044] The cooling module 4 is a coil group formed by a cooling water coil and a five-stage material coil. The discharge end of the five-stage material coil is connected to the material processing completion pipe outside the heat exchanger, the feed end of the cooling water coil is connected to the cooling water inlet pipe outside the heat exchanger, and the discharge end of the cooling water coil is connected to the cooling water outlet pipe outside the heat exchanger.

[0045] In a preferred embodiment 3, the material heat recovery module 1, the steam condensate heat recovery module 2, the steam heating module 3, and the cooling module 4 are all housed separately within the same heat exchanger. This modification reduces the installation area required for additional equipment and controls wiring complexity by modifying the existing heat exchanger.

[0046] As a preferred embodiment 4, the initial material temperature of the material heat recovery module 1 does not exceed 65°C, and the temperature of the secondary material is at least 85°C.

[0047] The temperature of the tertiary materials formed by the steam condensate heat recovery module 2 is at least 95°C, and the temperature of the steam condensate entering the steam condensate heat recovery module 2 is 100~135°C.

[0048] The temperature of the four materials generated by the steam heating module 3 is 120~130℃.

[0049] The temperature of the six materials at the outlet of the cooling module 4 is 75~85℃.

[0050] Ensure the temperature and properties of the materials processed in the sixth stage.

[0051] As a preferred embodiment 5, a thermometer is provided at the outlet of the material coil of the steam heating module 3. The sensing end of the thermometer monitors the temperature of the generated five-stage material. A steam regulating valve is provided on the high-temperature steam feed pipe of the material of the steam heating module 3. The steam regulating valve is linked with the thermometer measuring the temperature of the five-stage material through the plant's control system.

[0052] To facilitate automatic control, the steam regulating valve FCV3125 automatically adjusts the temperature based on the temperature set by the thermometer TT31805. When the temperature is lower than the minimum value of the set temperature range, the thermometer TT31805 increases the flow rate of the steam regulating valve FCV3125 through the control system, thereby increasing the flow rate of high-temperature steam to raise the temperature until it returns to the set range, maintaining the flow rate of the steam regulating valve FCV3125. When the temperature is higher than the maximum value of the set temperature range, the thermometer TT31805 decreases the flow rate of the steam regulating valve FCV3125 through the control system, thereby decreasing the flow rate of high-temperature steam to lower the temperature until it returns to the set range, maintaining the flow rate of the steam regulating valve FCV3125. The temperature of the four materials needs to be controlled between 120℃ and 130℃.

[0053] As a preferred embodiment 6, the high-temperature steam feed pipe is also equipped with a steam pneumatic switch valve and a pressure gauge. The steam pneumatic switch valve FV31325 protects the regulating valve, serving as an alternative shutdown operation in case of regulating valve failure, facilitating maintenance. The pressure gauge PI31695 is used to monitor whether the pressure in the steam feed pipe is normal, thereby assisting in judging whether the subsequent process is normal. For example, if the pressure is higher than the theoretical pressure of the steam at this flow rate, there may be blockage in the subsequent process or abnormality of the regulating valve.

[0054] As a preferred embodiment 7, a thermometer is provided at the outlet of the material coil of the cooling module 4. The sensing end of the thermometer monitors the temperature of the generated six materials. A cooling water regulating valve is provided on the cooling water inlet pipe. The control system of the cooling water regulating valve is linked with the thermometer that measures the temperature of the six materials.

[0055] To facilitate automatic control, the cooling water regulating valve FCV31216 automatically adjusts its flow rate based on the temperature value set by the thermometer TT31806. When the temperature is below the minimum value of the set temperature range, the thermometer TT31806 reduces the flow rate of the cooling water regulating valve FCV31216 through the control system, thereby reducing the cooling water flow to raise the temperature until it returns to the set range, maintaining the flow rate of the cooling water regulating valve FCV31216. When the temperature is above the maximum value of the set temperature range, the thermometer TT31806 increases the flow rate of the cooling water regulating valve FCV31216 through the control system, thereby increasing the cooling water flow to lower the temperature until it returns to the set range, maintaining the flow rate of the cooling water regulating valve FCV31216. The temperature of the sixth-stage material at the outlet is generally controlled between 75℃ and 85℃.

[0056] The working principle of this utility model:

[0057] This patent adds a material heat recovery module 1 and a steam condensate heat recovery module 2 to the heat exchanger used in existing high-temperature sterilization devices. The newly added material heat recovery module 1 (i.e....) Figure 2The first section of the coil group from the right in the middle exchanges heat with the four materials heated by steam. The initial material is preheated to form the secondary material, saving the steam consumption of the steam heating module 3.

[0058] The heat energy of the fourth-stage material is recovered for preheating. After cooling, the fourth-stage material becomes the fifth-stage material, which then passes through cooling module 4 (i.e., Figure 2 The cooling water of the fourth section of the coil group from the right in the middle is cooled down to form six material discharges, and the five material discharges formed after cooling down save the cooling water consumption of the cooling module 4.

[0059] Secondary materials enter the steam condensate heat recovery module 2 (i.e. Figure 2 The second section of the coil group from the right in the middle exchanges heat with the high-temperature steam condensate, and the secondary material is thus preheated to form the tertiary material, saving the steam consumption of the steam heating module 3 and reducing the heat energy waste of the steam condensate.

[0060] The initial material undergoes primary preheating and secondary preheating in sequence during the process from initial material to tertiary material. This forms a multi-stage stepped heating before steam heating, avoiding single-stage rapid heating, reducing the amount of protein denaturation and precipitation, and effectively dissolving the special proteins that have precipitated before the material enters. This solves the problem of pipeline blockage and improves efficiency.

[0061] The addition of a steam regulating valve and an electronic thermometer after steam heating improves the automation level of steam heating and saves steam consumption through refined control; the addition of a cooling water regulating valve and an electronic thermometer after cooling water cooling improves the automation level of cooling and saves cooling water consumption through refined control.
