Description

Technical Field

[0001] The utility model relates to the technical field of edible oil processing, in particular to an edible oil steam deodorizing device. Background Art

[0002] The edible oil refining process includes key steps such as degumming, deacidification, decolorization, and deodorization. Deodorization removes low-molecular-weight aldehydes, ketones, unsaturated hydrocarbons, glycerides, and free fatty acid oxides from the oil. These substances have low boiling points. Under the same processing conditions, steam distillation is used to remove them under high temperature and high vacuum conditions, leveraging the volatility difference between these substances and triglycerides. During the liquid-gas mass transfer process, contact between the vapor and liquid causes the vapor to become saturated with the volatile substances, releasing the oil, thereby removing odorous substances from the oil and raising the smoke point of the edible oil, thereby improving its flavor. Furthermore, during the gas-liquid mass transfer process, the water vapor pressure can also destroy some pigments in the edible oil, making it brighter and more transparent.

[0003] Existing deodorization processes and corresponding equipment can meet the deodorization needs of common edible oils. High temperature helps remove odorous substances in oils and fats and can significantly shorten the deodorization time. However, odorous substances enter the vacuum system along with water vapor and easily accumulate in the vacuum system, clogging the vacuum system. Utility Model Content

[0031] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The technical solutions of the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of the overall structure of an edible oil steam deodorizing device according to an embodiment of the present invention;

[0034] Figure 2 It is a structural schematic diagram of a deodorizing tank 1 shown in an embodiment of the present utility model.

[0035] like Figure 1 and Figure 2 As shown, a cooking oil vapor deodorizing device provided by Example 1 of the present utility model includes a deodorizing tank 1 and a heat exchanger 2;

[0036] The deodorizing tank 1 has a first chamber 11 and a second chamber 12. The first chamber 11 is provided with a condensing mechanism 3 connected to the second chamber 12. The condensing mechanism 3 is used to cool the deodorizing water vapor.

[0037] A medium cavity 21 is provided in the heat exchanger 2, and a heat transfer tube 22 is provided in the medium cavity 21. The heat transfer tube 22 is arranged in a wavy structure. The first end of the heat transfer tube 22 is connected to the first chamber 11, and the second end is connected to a negative pressure medium cavity 21 connected to the steam generator 4 and the soft water storage tank 5.

[0038] In this embodiment, the steam generator 4, the soft water storage tank 5, and the vacuum steam deodorization of the deodorizer 1 are prior art, and their working principles are not described in detail here. The edible oil steam deodorization device includes a deodorizer 1 and a heat exchanger 2, wherein the deodorizer 1 is provided with a first chamber 11 and a second chamber 12. The first shell is connected to the second chamber 12 through a condensing mechanism 3. After the edible oil is stripped by the second chamber 12, the water vapor flows into the first chamber 11 under the action of negative pressure. Part of the water vapor is captured and liquefied by the condensing mechanism 3, achieving primary separation. The first chamber 11 is connected to the heat exchanger 2. Under the action of negative pressure, the water vapor flows through the heat transfer tube 22 and undergoes heat exchange with the soft water after the heat exchanger 2. This realizes waste heat recovery of the water vapor and secondary separation, thereby increasing the initial temperature of the water source supplied to the steam generator 4 and effectively reducing the energy consumption of the steam generator 4.

[0039] In a preferred embodiment, a partition 13 is obliquely arranged in the deodorizing tank 1 of the above-mentioned edible oil vapor deodorizing device, and a mounting hole is provided on the partition 13, and the condensing mechanism 3 is installed on the mounting hole; a waste interface 100 is also provided on the deodorizing tank 1, and the waste interface 100 is connected to the first chamber 11.

[0040] A partition 13 is provided in the deodorizing tank 1. The partition 13 divides the deodorizing tank 1 into two chambers, namely the first chamber 11 and the second chamber 12. A mounting hole is provided on the partition 13, and the condensing mechanism 3 is mounted on the mounting hole of the partition 13. After the water vapor from the steam generator 4 enters the second chamber 12, it conducts vapor-liquid mass transfer with the edible oil. During the mass transfer process, the low molecular weight aldehydes, ketones, unsaturated hydrocarbons, glycerides, and free fatty acid oxides and other substances in the edible oil are dissolved. Under vacuum conditions, the water vapor containing the above substances flows through the condensing mechanism 3 into the first chamber 11. After the water vapor encounters the condensing mechanism 3, its path of travel is blocked by the condensing mechanism 3, and a process of liquefaction and condensation occurs. The liquefied water vapor converges in the first chamber 11. The partition 13 is arranged at an angle to facilitate the discharge of all waste working fluids (i.e., water containing low molecular weight aldehydes, ketones, unsaturated hydrocarbons, glycerides, and free fatty acid oxides and other substances) from the waste interface.

[0041] Based on the above specific implementation, technicians in this field can also connect a container for collecting waste working fluid to the waste interface, thereby ensuring that the cooking oil vapor deodorization device can perform deodorization work for a long time, eliminating the need to clean the first chamber 11.

[0042] In a preferred embodiment, in order to avoid the liquefied waste working medium formed on the lower end surface of the partition 13 (i.e., the end surface facing the second chamber 12), a second waste interface can be provided on the deodorizing tank 1. The waste interface is similarly connected to a container so that the waste working medium formed on the lower end surface of the partition 13 can be directly collected in the container through the inclined partition 13.

[0043] Furthermore, in order to slow down the heat transfer effect of the partition 13 on water vapor and reduce the liquefaction of water vapor at the lower end surface of the partition 13, the partition 13 of the edible oil vapor deodorizing device includes a shell and a heat insulation layer wrapped in the shell.

[0044] In a preferred embodiment, the housing of the cooking oil vapor deodorizer is made of stainless steel or glass, and the thermal insulation layer is an aerogel layer. When stainless steel is used as the housing, multiple pieces of stainless steel can be welded together to form a seal. When glass is used, an open hollow glass panel can be blown, and the aerogel layer can be placed inside the hollow glass panel, which can then be sealed together.

[0045] In a preferred embodiment, the aerogel layer of the edible oil steam deodorizing device is a silicon-based aerogel, and the thickness of the silicon-based aerogel is 30 to 65 mm.

[0046] Compared with the prior art, the edible oil vapor deodorization device provided by the present invention realizes multiple separations of the waste working medium by setting up a condensation mechanism 3 and a heat exchanger 2, and the inclined partition 13 and the waste interface can ensure long-term edible oil deodorization work.

[0047] In a preferred embodiment, Figure 3 As shown, the condensing mechanism 3 of the cooking oil vapor deodorizing device comprises a tube body 31, a rib plate 32, and a cap 33. The tube body 31 is mounted on the mounting hole, and the cap 33 is connected to the tube body 31 via the rib plate 32. The bottom of the cap 33 has a wide opening that radially tapers from the bottom toward the top, and the diameter of the opening is larger than the diameter of the tube body 31. Water vapor liquefies on the cap 33 and flows along the sidewall of the cap 33 from the opening onto the partition 13. By setting the opening diameter larger than the diameter of the tube body 31, the liquefied water vapor is prevented from falling into the second chamber 12.

[0048] In a preferred embodiment, a flow channel is provided on the cap 33 of the edible oil steam deodorizing device, and the flow channel is connected to the soft water storage tank 5 and the steam generator 4 through a pipeline.

[0049] In a preferred embodiment, the edible oil vapor deodorization device further includes a waste liquid container 6, which is connected to the various troughs of the heat transfer tube 22 via a pipe. The waste liquid container 6 can be a glass kettle or a stainless steel tank. After being connected to the heat transfer tube 22, under the action of negative pressure, the water vapor is liquefied through heat exchange in the heat transfer tube 22, and then converges at the troughs of the heat transfer tube 22. Then, the water vapor enters the waste liquid container 6 by its own weight, thereby avoiding the formation of a liquid seal on the water vapor in the heat transfer tube 22.

[0050] In a preferred embodiment, a regulating valve 7 is further provided on the pipeline connecting the soft water storage tank 5 of the edible oil vapor deodorization device and the medium cavity 21 , and the regulating valve 7 is used to adjust the flow rate of the soft water storage tank 5 .

[0051] Specifically, the regulating valve 7 can be controlled by a control system, or a thermometer can be set on the pipeline conveying the steam generator 4, and the operator can adjust the opening of the regulating valve 7 according to the temperature to increase the inlet temperature of the soft water in the steam generator 4.

[0052] In a preferred embodiment, the deodorizing tank 1 of the edible oil vapor deodorizing device includes a tank body 10, which is provided with a vacuum steam connection port 101, a steam inlet 102, an oil inlet 103, an oil outlet 104, an oil drain port 105, an electric heating connection port 106, a thermometer interface 107, and a sight glass port 108. The vacuum steam connection port 101 is connected to the heat transfer pipe 22. A steam injection pipe 109 is also provided in the tank body 10, and the steam injection pipe 109 is connected to the steam inlet 102. Specifically, after starting the device, a certain amount of edible oil is poured into the tank body 10 through the oil inlet 103, the vacuum system 8 is started to vacuum the deodorizing tank 1, the heating pipe is turned on to heat the edible oil, and when the temperature of the edible oil reaches a preset temperature, the steam generator 4 is started to deliver water vapor to the tank body 10, thereby performing the edible oil vapor deodorization process.

[0053] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0054] While various embodiments of the present invention have been described above, the above descriptions are illustrative and non-exhaustive, and are not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
