DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

1 shows an embodiment of the operating structure of a heat exchanger according to the present invention.

Referring to FIG. 1, a heat exchanger for regulating and discharging a homogenized raw material according to the present invention includes a circulation unit 12 for circulating the raw material. A cooling fluid supply unit (14) for supplying cooling fluid to the circulation unit (12); An adjusting unit (15) for adjusting the amount of fluid supplied from the cooling fluid supply unit (14); A sensor 16 for detecting the temperature of the raw material discharged from the circulation unit 12; And a control module (11) for determining the opening and closing level of the control unit (15) according to a predetermined temperature range based on the information transmitted from the sensor (16).

The heat exchanger according to the present invention may have a function of finally treating and discharging the raw material homogenized in the homogenizer. A homogenizer may be applied to the food sector such as foodstuffs, powdered milk, margarine or mayonnaise, the chemical field such as ink, soap, fuel oil, vitamins, toothpaste, paint or perfume, pharmaceuticals, dyes, It does not. The pressure applied to the homogenizer may be 500 to 80,000 psi, but may be suitably adjusted depending on the product being applied. In the homogenizer, the raw material can be pulverized to a predetermined size by cavitation, turbulence, or shear force while passing through a homogeneous unit formed of nanocells made of, for example, a diamond material. The pulverized raw material is supplied to the heat exchanger and finally treated and discharged.

The heat exchanger according to the present invention may have a function of uniformly dispersing the pulverized raw material in the dispersion medium in the circulation process. In the process of homogenization, the temperature control can be a major factor affecting the properties of the product. According to the present invention, the temperature inside the heat exchanger can be automatically adjusted within a predetermined range. The homogenization process can be performed in any homogenizer and the present invention is not limited by the type of homogenizer.

According to the present invention, the temperature inside the heat exchanger can be controlled by a fluid such as cooling water, and the supply amount or supply speed of cooling water can be controlled by a proportional control valve in which the opening and closing level can be electronically controlled. The valve or the flow rate control may be performed in the separately installed control module 11. A suitable temperature range at the control module 11 may be predetermined and entered and a valve or flow rate control may be made based on the information delivered from the sensors 16a, 16b. The control can be done in the same way as proportional integral-derivative control (PID), for example, and the operation can be adjusted as a whole according to the program logic control (Program Logic Control). This control structure allows the temperature of the heat exchanger to be precisely and accurately controlled. The control module 11 can also be housed in a control box installed independently of the heat exchanger and allows the operation of the heat exchanger to be controlled while being related to other operations of the homogenizer. This allows automatic control of the entire homogenizer.

The raw material supply unit 13 may include a homogeneous unit in which the raw material is crushed and a controllable on / off valve which can be a transport pipe capable of fluid transport. The raw material supply unit 13 may also include an inlet provided in the heat exchanger. The structure of the raw material supply unit 13 is not particularly limited, and it may have any structure capable of supplying the pulverized raw material into the heat exchanger.

The raw material supply unit 13 can be installed inside the heat exchanger and can be arranged, for example, in a spiral shape. The raw material is circulated in the raw material supply unit 13, and the raw material is uniformly dispersed in the dispersion medium, so that the stabilization can be achieved. The raw material can be cooled while being circulated and the cooling water can be supplied from the cooling water supply unit 14 for this purpose. The cooling water can circulate in the direction opposite to the direction in which the raw material is circulated in the starting direction from the end portion of the circulation unit 12. [ By supplying the cooling water in the reverse direction in this way, the cooling efficiency can be increased, and at the same time, the raw material can be discharged in the required temperature range.

The first sensor 16a may be installed in the circulation unit 12 and the second sensor 16b may be installed in the cooling water supply unit 14 as necessary. A detection value such as temperature or flow rate detected by the first sensor 16a or the second sensor 16b may be transmitted to the control module 11. [ Then, the control module 11 can control the open / close level of the control unit 15 based on the measured measurement data. The supply amount or the supply speed of the cooling water supplied from the cooling water supply unit 14 can be controlled accordingly. The control module 11 can obtain data related to the open / close level from the database 17. The control module 11 can retrieve data corresponding to the detection value from the database 17 according to the transmitted detection value. The opening and closing level of the control unit 15 can be determined according to the matching data.

The operation of the heat exchanger having such a structure will be described below.

Figure 2 shows an embodiment of a method of operating a heat exchanger according to the invention.

Referring to FIG. 2, basic information may first be input for temperature control of the heat exchanger (S21). The basic information can be, for example, the characteristics of the raw material, the pressure in the homogeneous unit depending on the pressure of the hydraulic cylinder and the corresponding temperature level or the speed of the raw material. The basic information can be inputted to the control module, and the control module can control the supply amount of the cooling water by controlling the control unit according to the inputted information. And the temperature of the pulverized raw material discharged from the heat exchanger can be detected (S22).

The detected temperature value may be transmitted to the control module and it may be determined whether it is within an error range (S23). If it is out of the error range (NO), the input value of the basic information can be set again (S21). On the other hand, if the detected temperature value is within the allowable error range (YES), the cooling water can be supplied under the predetermined condition (S24).

When the homogenizer is operated and a predetermined time has elapsed, the environmental condition may be changed (S25). Accordingly, the control module can adjust the cooling water supply level to a predetermined amount (S26). And it needs to be judged whether the adjustment corresponds to the appropriate level. In this case, when the operating condition is changed and the amount of the cooling water is changed, the temperature value may be feedback (S261). Then, the control module determines whether the temperature value is within the allowable range based on the feedback value (S27). If it is within the allowable range (YES), the supply level of cooling water can be maintained until the cooling water is adjusted again. On the other hand, if the allowable range is exceeded (NO), factor analysis can be performed (S28). The factor analysis means, for example, the change in temperature depending on the supply pressure, the temperature of the cooling water or the amount of the cooling water. Then, the control can be performed according to the degree of deviation or the controllable factor (S29). And the amount of cooling water can be regulated accordingly (S26). And again the above process can be repeated.

According to the present invention, the change of the operating factor and accordingly the control of the cooling water can be made according to the proportional integral-differential control (PID). Proportional-Integral-Derivative Control can be applied. The proportional-integral-differential control is a feedback control method. For example, the proportional integral-differential control can be compared with a reference value according to a raw material stored in the control module by measuring a temperature value to be controlled. The error is then calculated to determine, for example, the amount of cooling water, the temperature of the cooling water, or the environmental conditions inside the heat exchanger. For proportional integral-derivative control of the heat exchanger, the amount of cooling water can be controlled primarily. And the temperature of the cooling water is controlled and finally the environmental conditions inside the heat exchanger can be changed. Alternatively, the amount of cooling water can be adjusted first and then the amount of cooling water and the temperature of the cooling water can be controlled at the same time. The control module may control the factor for proportional integral-derivative control according to a predetermined method.

The embodiment shown in FIG. 2 is illustrative and the temperature of the heat exchanger can be controlled in various ways, and the present invention is not limited to the embodiments shown.

An embodiment of a homogenizer to which a heat exchanger with temperature control according to the present invention is applied will be described below.

FIG. 3 shows an embodiment of a homogenizer to which a heat exchanger according to the present invention is applied.

The pressure module 40 may first be controlled by the control module 20 for operation of the homogenizer. The pressure module 40 may include, for example, a hydraulic cylinder, a plunger actuated by a hydraulic cylinder, a pump for actuation of the hydraulic cylinder, a solenoid block or a motor. The control module 20 may be installed in a separate position from the homogenizer and the control module 20 may comprise a control unit 21 having a microprocessor or central processing unit, an input unit 22 for inputting control commands, Or a display unit 23 for displaying an input situation and a storage unit 24 for storing data related to the operation.

The pressure to be generated in the pressure module 40 is determined according to the kind of the raw material and can be inputted through the input unit 22. [ At the same time, the temperature of the raw material to be discharged from the heat exchanger 31 can be input. The temperature of the heat exchanger 31 can then be detected by the temperature sensor 33a. The detected value may be transferred to the control module 20 and the control unit 21 may retrieve the value stored in the storage unit 24 to determine the amount of cooling water that matches the temperature of the input raw material.

When the pressure module 40 is operated, the pressure can be transmitted to the homogenizer module 50 through the first conveyance pipe 41 and the raw material to be crushed can be introduced into the conveyance pipe 41. The raw material pulverized in the uniform module 50 may be transferred to the discharge module 30 through the second transfer pipe 51.

A temperature sensor 33a may be installed in the discharge port 311 or the heat exchanger 31. The opening / closing control unit 34 may be installed in the adjusting unit 32 as required. The opening / closing control unit 34 may be connected to, for example, a detection sensor 33b for detecting the condition of the cooling water. However, the opening / closing control unit 34 may be installed as required, and the detection sensor 33b may be directly connected to the control module 20. [ The opening and closing control unit 34 can periodically communicate with the control module 20 while adjusting the opening and closing level of the adjusting unit 32. [ The opening and closing control unit 34 has an advantage that the temperature stabilization can be rapidly performed by controlling the adjusting unit 32 quickly according to the condition of the cooling water.

The pulverized raw material is circulated in the heat exchanger (31) and discharged to the discharge port (311). The cooling water supplied from the cooling water supply source 35 is regulated in the regulating unit 32 through the first circulation line 351 and supplied to the inside of the heat exchanger 31 through the second circulation line 352 . The cooling path of the cooling water can be opposite to the circulating path of the raw material and the cooling water circulated inside the heat exchanger 31 can be discharged through the discharge line 30 and transferred to the cooling water supply source 35 .

The temperature of the discharged raw material can be changed according to a change in the operating environment of the homogenizer and can be detected by the temperature sensor 33a. If the detected value is out of the permissible range, the control unit 21 makes a search for the appropriate control condition from the storage unit 24 and retrieves the most matching data for adjustment. Then, the retrieved data can be transferred to the opening / closing control unit 34 and accordingly the controlling unit 32 can be controlled. Then the temperature can again be detected by the temperature sensor 33a and the control unit 32 can be controlled accordingly. And the amount of cooling water or the temperature of the cooling water can be controlled, for example, according to the proportional integral-derivative control method as described above. Suitable cooling means may be provided in the cooling water supply 35 for temperature control of the cooling water.
