[0002] To remove unpleasant odors from vegetable oils, increase their smoke point, improve their flavor, enhance safety, and extend their shelf life, vegetable oils need to undergo deodorization treatment during production. Currently, the industry uses the dry saturated steam direct distillation method under vacuum conditions to deodorize oils. The stability of the vacuum system directly affects the quality of the deodorized oil.
[0003] In the intermittent vegetable oil deodorization process, due to the small designed capacity, most companies now use vacuum collection tanks with condensation devices to intermittently collect the extracted hot waste gas, distillate, and a small amount of free fatty acids. Because the collection tank has a limited volume and cannot automatically discharge wastewater, distillate overflow often occurs, causing the distillate to be drawn into the vacuum pumps of each stage of the vacuum system. This can lead to unnecessary machine jams, failure to meet process requirements for vacuum, and other accidents, posing safety hazards to the quality of the finished oil and increasing unnecessary equipment maintenance costs.

[0023] like Figure 1-2 As shown, a condensate self-draining device for a high-vacuum deodorization system includes:
[0024] A condensation assembly is used to condense the distillates in the exhaust gas into liquid, while reducing the temperature of the exhaust gas entering the vacuum system.
[0025] The self-draining mechanism includes a collector housing 9, an upper collector head 9-1, a lower collector head 9-2, a conical baffle 17, and a connecting pipe 10. The upper collector head 9-1 is located below the condenser assembly and above the collector housing 9. The lower collector head 9-2 is located below the collector housing 9. The conical baffle 17 is located on the inner wall of the collector housing 9. The connecting pipe 10 is connected to the collector housing 9, with both ends located on the upper and lower sides of the conical baffle 17. The collector is equipped with a gravity check valve 10-1. An upper chamber gas distribution pipe 11 is connected to the upper end cap 9-1 of the collector. A lower chamber gas distribution pipe 12 is connected to the collector housing 9 and located below the conical partition 17. An electrically controlled actuator valve 13 is connected to the upper chamber gas distribution pipe 11 and the lower chamber gas distribution pipe 12. An air balance pipe 14 is connected to the electrically controlled actuator valve 13. A pair of liquid level sensors 15 are arranged vertically inside the collector housing 9. A drain assembly is arranged at the bottom of the lower end cap 9-2 of the collector.
[0026] The condensation assembly includes:
[0027] A flow guide head 1, wherein a partition 2 is provided inside the flow guide head 1, and an air inlet pipe 1-1 and an exhaust pipe 1-2 are connected and arranged on the flow guide head 1 and on both sides of the partition 2;
[0028] The condenser housing 5 is located below the flow guide head 1 and above the collector upper head 9-1. A pair of condenser orifice plates 3 are provided on the upper and lower sides of the interior of the condenser housing 5. Multiple condenser tubes 4 are provided on the pair of condenser orifice plates 3. Cooling water inlet pipe 6 and cooling water outlet pipe 7 are connected and arranged on the upper and lower sides of the condenser housing 5.
[0029] Multiple baffles 8 are staggered inside the condenser shell 5, and multiple condenser tubes 4 pass through the multiple baffles 8.
[0030] The drainage assembly includes a drainage pipe 19, a drainage pump 20, and a valve 21. The drainage pipe 19 is connected to the bottom of the lower end cap 9-2 of the collector. The drainage pump 20 is installed on the drainage pipe 19. The valve 21 is installed on the drainage pipe 19 and located on the outlet side of the drainage pump 20.
[0031] The collector's upper end cap 9-1 is equipped with a splash-proof baffle 16.
[0032] An observation window 18 is provided on the collector housing 9.
[0033] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:
[0034] According to the instruction manual Figure 1-2 As can be seen, the conical baffle 17 of this utility model is set inside the collector housing 9, dividing the inside of the collector housing 9 into an upper liquid collection chamber 9-3 and a lower liquid storage chamber 9-4. A pair of liquid level sensors 15 are set vertically inside the collector housing 9 and connected to the control system circuit. They can transmit the detected signals to the PLC system to control the state of the electrically controlled actuator valve 13. In use, the condensation assembly is set between the deodorization pipeline and the vacuum system. The condensation assembly condenses the waste gas containing distillate into liquid and reduces the temperature of the waste gas entering the vacuum system, thereby causing the condensate to collect inside the liquid collection chamber 9-3. The liquid level inside the liquid storage chamber 9-4 is lower than the height of the liquid level sensor 15 below. Under the control of the PLC system, the electrically controlled actuator valve 13 is set to a state where the upper chamber gas distribution pipe 11 and the lower chamber gas distribution pipe 12 are connected, so that the liquid collection chamber 9-3 and the liquid storage chamber 9-4 are under the same pressure, and the gravity check valve 10 on the connecting pipe 10... 1. When the circuit is open, condensate flows from the collection chamber 9-3 into the storage chamber 9-4 through the connecting pipe 10. When the condensate level in the storage chamber 9-4 reaches the position of the upper level sensor 15, the PLC system drives the electrically controlled actuator valve 13 to operate. The valve position of the electrically controlled actuator valve 13 is in the state where the lower chamber gas distribution pipe 12 is connected to the air balance pipe 14, so that the storage chamber 9-4 is connected to the atmosphere. At this time, the gravity check valve 10-1 is closed, so that the condensate in the collection chamber 9-3 cannot flow into the storage chamber 9-4. Finally, the condensate in the storage chamber 9-4 is discharged to the outside through the drainage component. After drainage, the PLC program is re-executed from initialization to complete the closed-loop control. This utility model realizes automatic continuous sewage discharge operation through the automatic reversing of the electrically controlled actuator valve 13, while reducing the temperature of the exhaust gas entering the vacuum system, effectively preventing the distillate from being drawn into the vacuum pumps of each stage of the vacuum system, avoiding unnecessary equipment maintenance, providing a continuous and stable vacuum condition for the deodorization process, and improving the quality of the finished oil.
[0035] One possible implementation is that, during the condensation of the distillate, the inlet pipe 1-1 on the guide head 1 is connected to the deodorization pipeline, and the exhaust pipe 1-2 is connected to the vacuum system. When the vacuum system is activated, a negative pressure is created in the guide head 1 and the condenser tubes 4. The cooling water inlet pipe 6 is connected to the refrigeration unit outlet, and the cooling water outlet pipe 7 is connected to the refrigeration unit inlet. The refrigeration unit provides low-temperature water at approximately 5 degrees Celsius. The multiple condenser tubes 4 are divided into a first pass 4-1 and a second pass 4-2, with the middle position being controlled by the guide head 1. The baffle 2 inside the flow head 1 separates the flow. During use, the waste gas containing distillate enters the flow head 1 through the inlet pipe 1-1, and then enters the first tube 4-1 through the baffle 2, so that some of the distillate is condensed. The waste gas containing distillate that is not condensed enters the second tube 4-2 after passing through the collector upper head 9-1. At this time, all the distillate is condensed. The condensate flows back into the collection chamber 9-3 in the second tube 4-2, thus completing the condensation process of the distillate.
[0036] One possible implementation is that multiple baffles 8 are staggered inside the condenser shell 5, so that the cooling water can perform turbulent heat exchange.
[0037] One possible implementation is that when the condensate level inside the collector housing 9 reaches the position of the upper level sensor 15, the drain pump 20 is started, the valve 21 on the drain pipe 19 is opened, and the condensate inside the collector housing 9 is discharged outward.
[0038] One possible implementation is that the collector head 9-1 is provided with a splash guard 16 inside, which prevents the falling condensate from splashing.
[0039] One possible implementation is to provide an observation window 18 on the collector housing 9, which facilitates observation of the conditions inside the collector housing 9.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
