Description

Technical Field

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

[0002] During the frying process, the frying oil will undergo hydrolysis, oxidation, polymerization and other reactions under high temperature and interaction with factors such as moisture and oxygen in the food, generating substances such as free fatty acids, oxidized triglycerides, and oxidized triglyceride polymers.

[0003] The free fatty acid content affects the acid value of edible oils, which reflects the degree of oxidation in the oil. A higher acid value indicates a higher degree of oxidation and lower quality. Free fatty acids, oxidized triglycerides, and oxidized triglyceride polymers are collectively referred to as polar components. The content of these components directly impacts the quality of edible oils and their health effects. A higher content of these polar components indicates a higher degree of oxidation and a greater negative impact on human health.

[0004] my country's national food safety standard, GB 2716, stipulates that frying oil with a polar component content of 27% or greater and an acid value exceeding 5 mg / g must be discarded and cannot be used as frying oil. Therefore, during the frying process, frying oil must be filtered to remove polar components and extend its frying life.

[0005] Existing cooking oil filtration systems typically filter frying oil by mixing filter powder with the frying oil for a set period of time, then taking a sample of the mixture for testing. If the sample passes the test, the mixture is then filtered.

[0006] The existing cooking oil filtration system is used to filter the oil used for frying, which takes a long time and has low filtration efficiency. Utility Model Content

DETAILED DESCRIPTION

[0036] Existing cooking oil filtration systems typically include a mixing tank and a filter. When filtering frying oil, filter powder and the frying oil are typically placed in a mixing tank and mixed for a set period of time (e.g., one hour). The resulting mixture is then sampled and tested. If the test passes, the mixture is filtered. If it fails, more filter powder is added to the mixing tank, and the mixture is mixed again for a set period of time, followed by sample testing until it passes.

[0037] In practical applications, when testing a mixture of oil filter powder and frying oil, the main tests include acid value testing and polar component testing of the mixture.

[0038] The acid value of a mixture is typically measured using a near-infrared analyzer. Specifically, the sample is placed in a measuring vessel and irradiated directly with high-intensity, broadband white light. The diffusely reflected light from the sample is collected and used to determine the acid value of the sample.

[0039] Testing for polar components in a mixture is typically performed using an edible oil quality tester. A sample is placed in a stainless steel container with enough oil to submerge the tester's sensor. Once the oil temperature drops to approximately 60°C, the sensor can be immersed in the oil and the polar component content can be read on the tester's screen.

[0040] However, when using the existing edible oil filtration system to filter frying oil, the oil filter powder and the frying oil are first filtered after being mixed for a set time, and the filtered frying oil is taken out as a sample to detect the acid value and polar components of the frying oil. The acid value and polar components of the frying oil are not detected in real time, resulting in a long processing time and low filtration efficiency.

[0041] Furthermore, when filtering frying oil using existing edible oil filtration systems, a fixed amount of filter powder is added each time. If a product fails the test, a fixed amount of filter powder must be added to the mixing tank again, even if the actual amount of filter powder required is less than the added amount. This results in excessive amounts of filter powder being added. Furthermore, when testing the acid value and polar components of the frying oil, the filtered frying oil must be sampled for testing, resulting in loss of frying oil. Excessive amounts of filter powder and the resulting loss of frying oil undoubtedly increase filtration costs.

[0042] To address this problem, the present invention provides an edible oil filtration system, in which an oil quality detection component is provided. The oil quality detection component can perform real-time oil quality detection operations on the mixture of the oil to be detected and the adsorbent. In this way, when the oil quality detection result is less than a preset oil quality detection target, the control component can control the filtering component to perform a filtering operation on the mixture of the oil to be detected and the adsorbent, without having to wait for the mixture of oil filter powder and frying oil to reach a set time, and without having to separately take out the oil filter powder and frying oil for sample testing, thereby shortening the time required for filtration and improving filtration efficiency.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] Reference Figure 1 The embodiment of the present invention provides an edible oil filtration system 10, which may include: a mixing component 11, a filtering component 12, an oil quality detection component 13, and a control component 14.

[0045] The mixing assembly 11 is suitable for performing a mixing operation between the oil to be tested and the adsorbent;

[0046] The filtering component 12 is connected to the mixing component 11 and is suitable for performing a filtering operation on the mixture of the oil to be tested and the adsorbent;

[0047] The oil quality detection component 13 is adapted to perform a real-time oil quality detection operation on the mixture of the oil to be detected and the adsorbent;

[0048] The control component 14 is connected to the oil quality detection component 13 and is suitable for obtaining the oil quality detection result of the oil quality detection component 13 and controlling the filtering component 12 to perform a filtering operation on the mixture of the oil to be detected and the adsorbent when the oil quality detection result is less than a preset oil quality detection target.

[0049] By setting up an oil quality detection component 13 to perform a real-time oil quality detection operation on the mixture of the oil to be detected and the adsorbent, once the oil quality detection result reaches the preset oil quality detection target, the filter component 12 can be controlled to perform a filtering operation on the mixture of the oil to be detected and the adsorbent, without having to wait for the mixing time of the oil to be detected and the adsorbent to reach the preset set time, thereby shortening the time required for filtration. In addition, since the oil quality detection component 13 can directly perform oil quality detection on the mixture of the oil to be detected and the adsorbent, there is no need to separately remove a portion of the mixture of the oil to be detected and the adsorbent as a sample to achieve detection, thus avoiding the increase in filtration time due to sampling, and further shortening the time required for filtration. In addition, it can also avoid the loss of the oil to be detected due to separately removing a portion of the mixture of the oil to be detected and the adsorbent as a sample, thereby reducing the filtration cost.

[0050] Figure 2 This is a structural diagram of an edible oil filtration system in another embodiment of the present invention. Figure 2 The mixing assembly may include a mixing tank 111 and a mixing drive assembly connected to the mixing tank 111. The mixing tank 111 is adapted to provide a chamber for accommodating the oil to be tested and the adsorbent. Once the oil to be tested and the adsorbent are placed in the chamber, the mixing drive assembly can mix the oil to be tested and the adsorbent within the chamber. The mixing tank 111 is typically cylindrical.

[0051] In the specific implementation, refer to Figure 2 The hybrid drive assembly may include an oil pump 112, a motor 113, and a stirring blade 114. The oil pump 112 is connected to the oil output port 111a of the mixing tank 111 and the oil input port of the filter assembly. The motor 113 is connected to the stirring blade 114, which is located in the mixing tank 111. The oil pump 112 and the motor are connected to the control assembly 14.

[0052] In one embodiment, in order to remove odor from the oil to be tested, the hybrid drive assembly may further include a vacuum pump 115 . The vacuum pump 115 is connected to the mixing tank 111 .

[0053] In a specific implementation, after the edible oil filtration system is powered on and a mixing operation is required, the control component 14 sends a control signal to the vacuum pump 115, causing the vacuum pump to evacuate the mixing tank 111. Simultaneously, the control component 14 can send a control signal to the motor to control the motor's rotation at a set speed, ensuring thorough mixing of the oil to be tested and the adsorbent. The motor's speed can be matched to the total weight of the oil to be tested and the adsorbent. Specifically, the control component 14 can control the motor's speed based on the total weight of the oil to be tested and the adsorbent.

[0054] At this time, the motor can drive the stirring blade 114 to rotate, thereby achieving a mixing operation of the oil to be tested and the adsorbent, so that the adsorbent can adsorb the polar components in the oil to be tested. Among them, the greater the weight of the oil to be tested and the adsorbent, the higher the speed of the motor and the faster the stirring blade rotates.

[0055] When the mixing operation needs to be stopped, the control component 14 can send a control signal to the motor 113 to control the reducer to reduce the speed of the motor 113, thereby gradually slowing down the rotation of the stirring blade 114 until it stops rotating, thereby stopping the mixing operation. At the same time, the control component 14 can control the vacuum pump 115 to stop vacuuming.

[0056] In a specific implementation, the oil quality detection component can be used to perform at least one oil quality detection operation, and the number of oil quality detection operations that can be performed is not limited.

[0057] In one embodiment of the present invention, referring to Figure 3 The oil quality detection component may include: an acid value detector 131. The acid value detector 131 is suitable for performing a real-time acid value detection operation on a mixture of the oil to be detected and the adsorbent.

[0058] In a specific implementation, the acid value detector 131 may have various structures, which are not limited here.

[0059] In one embodiment, referring to Figure 2 The acid value detector 131 may include: a first detection body 1311 and a first probe 1312 connected to the first detection body 1311; the first probe 1312 is in contact with the mixture of the oil to be detected and the adsorbent, and the first detection body 1311 is fixed on the mixing tank.

[0060] In a specific implementation, the outer surface of the first detection body 1311 can be provided with a first fixing portion, and the acid value detector 131 is fixed to the mixing tank via the first fixing portion. For example, the first fixing portion can be a thread, and accordingly, a threaded through hole can be provided on the mixing tank, and the first fixing portion is fixed to the mixing tank via the thread and the through hole. When the acid value detector 131 is fixed on the mixing tank, the free end of the first probe 1312 is located above the mixture of the oil to be detected and the adsorbent, thereby realizing acid value detection. Wherein, the position of the acid value detector 131 on the mixing tank 111 can be adjusted according to the mixture of the oil to be detected and the adsorbent. For example, the acid value detector 131 can be fixed to the top of the mixing tank 111.

[0061] In a specific implementation, the first detection body 1311 may generally include: a light source, a fiber optic sensor, a diffraction grating, and a diode detection array. The light source is suitable for irradiating white light onto the surface of the mixture of the oil to be detected and the adsorbent through the first probe; after the mixture of the oil to be detected and the adsorbent reflects the white light, it reaches the diffraction grating via the fiber optic sensor, and then is transmitted to the diode detection array after being split by the diffraction grating. In this way, after the mixture of the oil to be detected and the adsorbent diffusely reflects the white light, it can be incident on the fiber optic sensor, and then reach the diffraction grating through the fiber optic sensor, and then be transmitted to the diode detection array after being split by the grating. All spectral signals obtained by the diode detection array are irradiated onto a series of photodiodes arranged according to fixed wavelengths. Each photodiode senses a signal corresponding to a specific wavelength, thereby achieving the synchronous collection of continuous spectral signals.

[0062] In this case, the control component may include an acid value analyzer. The acid value analyzer is adapted to acquire the signal transmitted by the photodiode and obtain an acid value detection result. The wavelength of the signal transmitted by the photodiode is related to the acid value of the oil being tested. Therefore, the acid value of the oil being tested can be determined based on the wavelength of the signal transmitted by the photodiode.

[0063] In practical applications, the acid value detection target can be preset. For example, the preset acid value detection target can be 0.5 mg / g. At this time, when the acid value detection result is less than 0.5 mg / g, the control component can control the filtering component to perform a filtering operation on the mixture of the oil to be detected and the adsorbent.

[0064] Specifically, refer to Figure 2 The control component can turn off the motor 113 and the vacuum pump 115 in the mixing component when the acid value test result is less than 0.5 mg / g, and start the oil pump 112 when the speed of the stirring blade 114 drops below the preset speed value. The oil pump 112 transports the mixture of the oil to be tested and the adsorbent through the oil output port 111a of the mixing tank 111 to the filter component for continuous filtration.

[0065] In another embodiment of the present invention, referring to Figure 4 The oil quality detection assembly may include a polar component detector 132. The polar component detector 132 is in contact with the mixture of the oil to be detected and the adsorbent, and is suitable for performing a real-time polar component detection operation on the mixture of the oil to be detected and the adsorbent.

[0066] In a specific implementation, the polarity component detector 132 may have various structures, which are not limited here.

[0067] In one embodiment, the polar component detector 132 may include: a second detection body 1321 and a second probe 1322 connected to the second detection body 1321; the second probe 1322 contacts the mixture of the oil to be detected and the adsorbent, and the second detection body 1321 is fixed on the mixing tank.

[0068] In a specific implementation, the end portion where the second probe 1322 is connected to the second detection body 1321 may be provided with a second fixing portion, and the polarity component detector 132 is fixed to the mixing tank via the second fixing portion. For example, the second fixing portion may be a threaded portion, and correspondingly, a threaded through hole may be provided on the mixing tank, and the second fixing portion is fixed to the mixing tank via the threaded portion and the through hole. When the polarity component detector 132 is fixed to the mixing tank, the second probe 1322 may contact and penetrate into the mixture of the oil to be detected and the adsorbent (e.g., Figure 2 The position of the polar component detector 132 on the mixing tank can be adjusted according to the mixture of the oil to be detected and the adsorbent.

[0069] In a specific implementation, the second detection body 1321 may include an electromagnetic wave generating structure and a dielectric constant detection structure. The electromagnetic wave generating structure is adapted to generate electromagnetic waves that propagate through the mixture of the oil to be detected and the adsorbent within the second probe; and the dielectric constant detection structure is adapted to detect the dielectric constant value of the mixture of the oil to be detected and the adsorbent.

[0070] Specifically, when electromagnetic waves propagate through a mixture of the oil to be tested and the adsorbent, the molecules and ions in the mixture absorb and scatter the waves, affecting their propagation speed and wavelength. The dielectric constant detection structure can measure the propagation speed and wavelength of the electromagnetic waves in the mixture and calculate the dielectric constant of the mixture.

[0071] In this case, the control assembly may include a polar component analyzer adapted to obtain the dielectric constant value detected by the dielectric constant detection structure and obtain a polar component detection result based on the dielectric constant value. Specifically, the polar component analyzer may calculate the content of the polar component in the mixture based on the linear relationship between the dielectric constant value and the polar substance.

[0072] In practical applications, the polar component detection target can be preset. For example, the preset polar component detection target can be 2%. At this time, the control component can control the filtering component to perform a filtering operation on the mixture of the oil to be detected and the adsorbent when the polar component detection result is less than 2%.

[0073] Specifically, refer to Figure 2The control component 14 can turn off the motor 113 and the vacuum pump 115 in the mixing component when the polar component detection result is less than 2%, and start the oil pump 112 when the speed of the stirring blade 114 drops below the preset speed value. The oil pump 112 is used to transport the mixture of the oil to be tested and the adsorbent through the oil output port 111a of the mixing tank 111 to the filter component for continuous filtration.

[0074] In other embodiments, the oil quality detection component may include an acid value detector and a polar component detector at the same time. In this case, the control component 14 may control the filtering component to perform a filtering operation on the mixture of the oil to be detected and the adsorbent when the acid value detection result is less than a preset acid value detection target and the polar component detection result is less than a preset polar component detection target.

[0075] Furthermore, the oil quality detection component may also include components capable of performing other oil quality detection operations, which will not be specifically described here. It should be understood that regardless of the specific oil quality detection operation performed by the oil quality detection component, as long as the oil quality detection component detects oil quality in real time and the control component controls the system based on the oil quality detection results in real time, it is within the scope of protection of the present utility model.

[0076] In one embodiment of the present invention, referring to Figure 1 The edible oil filtering system may further include: an adsorbent component 15, which may be connected to the mixing component 11 and is suitable for providing an adsorbent.

[0077] In practical applications, the adsorbent is typically oil filter powder composed of magnesium silicate and silica gel. The content of magnesium silicate and silica gel in the adsorbent, as well as the total amount of adsorbent, can be adjusted based on the desired oil quality testing objectives. The adsorbent absorbs polar components in the oil being tested, thereby extending the service life of the oil.

[0078] In one embodiment of the present invention, in order to further reduce the adsorption cost, the adsorbent component 15 can be connected to the control component 14 and is suitable for providing an amount of adsorbent matching the oil quality detection result under the control of the control component 14.

[0079] Specifically, refer to Figure 2 The adsorbent assembly includes: an adsorbent quantitative tank 151, and a weighing module 152 and a switch module 153 located at the end of the adsorbent quantitative tank 151; the weighing module 152 is connected to the control component 14 and is suitable for weighing an amount of adsorbent that matches the oil quality test result under the control of the control component 14; the switch module 153 is connected to the control component 14 and is suitable for opening or closing the adsorbent quantitative tank 151 under the control of the control component 14.

[0080] In a specific embodiment, the adsorbent quantitative tank 151 is typically cylindrical. The adsorbent quantitative tank 151 has a receiving cavity containing adsorbent. When adsorbent needs to be added to the mixing tank 11, the control component 14 can control the weighing module 152 to weigh the adsorbent that matches the current oil quality test results, and control the switch module 153 to open the adsorbent quantitative tank 151. The adsorbent in the adsorbent quantitative tank 151 will fall into the mixing tank 11 under the action of gravity and mix with the oil to be tested. After the adsorbent is added, the control component 14 can control the switch module 153 to close the adsorbent quantitative tank 151. The switch module can be a valve.

[0081] The control component 14 can control the addition of adsorbent based on the current oil quality test results of the oil to be tested, rather than adding a fixed amount of adsorbent each time. Specifically, in the initial state, the control component 14 performs an initial test on the oil to be tested and obtains an initial oil quality test result. At this time, the control component 14 can control the weighing module 152 to weigh adsorbent that matches the initial oil quality test result. After the oil to be tested and the adsorbent are mixed for a certain period of time, an intermediate oil quality test result can be obtained again. If this intermediate oil quality test result is still greater than or equal to the preset oil quality test target, the control component 14 can control the weighing module 152 to weigh adsorbent that matches the intermediate oil quality test result, without adding adsorbent that matches the initial oil quality test result. This can reduce the amount of adsorbent added and further reduce filtration costs.

[0082] In the specific implementation, refer to Figure 2 The filter assembly may include a filter 121 and a filter screen located within the filter 121. The mixture of the oil to be tested and the adsorbent enters the filter 121 through the oil pump 112 and is filtered by the filter screen, thereby separating the oil to be tested from the adsorbent, thereby obtaining the oil to be tested that does not contain the adsorbent or has a very low adsorbent content.

[0083] In one embodiment of the present invention, referring to Figure 1 The edible oil filtering system 10 may further include an oil storage component 16, which is connected to the filtering component 12 and is suitable for storing the oil to be tested after the filtering operation is completed.

[0084] Specifically, refer to Figure 2 The oil storage assembly may include an oil tank 161 and an automatic valve. The oil tank 161 may contain the separated oil to be tested discharged from the filter assembly 12. The automatic valve may open or close the oil tank 161.

[0085] In actual application, the filter 121 is usually cylindrical. The bottom of the filter assembly is usually provided with an automatic valve, the top is usually provided with a pressure gauge, and the filter 121 is also provided with an air compressor. The pressure gauge can monitor the pressure in the filter 121 and feed it back to the control assembly 14. The control assembly 14 decides whether to squeeze the oil to be tested separated in the filter 121 into the oil storage tank 161 based on the pressure value in the filter 121. For example, when the pressure in the filter 121 is higher than 6mPa, the control assembly 14 can turn on the air compressor to compress the air, thereby squeezing the residual oil in the filter 121 into the oil storage tank 161, and then open the automatic valve of the filter 121 to discharge the residual adsorbent, and then close the automatic valve to carry out the next batch of operations.

[0086] In a specific implementation, the edible oil can be oil for frying or other oils.

[0087] As can be seen from the above content, the edible oil filtration system in the embodiment of the utility model can filter edible oil with high efficiency, and can also reduce the filtration cost and remove the odor in the edible oil.

[0088] In order to enable those skilled in the art to better understand and implement the present invention, the control method corresponding to the above-mentioned cooking oil filtering system is described in detail below.

[0089] Reference Figure 5 The present invention provides a method for controlling an edible oil filter system. The edible oil filter system can refer to the above Figures 1 to 4 The method may include the following steps:

[0090] Step 51 : During the mixing operation of the oil to be tested and the adsorbent, the oil quality testing component is controlled to perform the oil quality testing operation in real time to obtain the oil quality testing result.

[0091] In a specific implementation, the control component can control the flow of a fixed amount of oil to be tested from the oil pan into the mixing tank. After the oil to be tested from the oil pan enters the mixing tank, the control component can control the oil quality detection component to perform an initial oil quality test on the oil to be tested. For example, the control component can perform an initial acid value test on the oil to be tested to obtain an initial acid value test result, and perform a polar component test on the oil to obtain an initial polar component test result.

[0092] After the initial test, the control component can control the amount of adsorbent added based on the initial test results. Once the adsorbent is added, the mixing drive component can be controlled to perform a mixing operation on the mixture of the oil to be tested and the adsorbent. During the mixing operation, the oil quality detection component is controlled to perform an oil quality detection operation in real time to obtain the oil quality detection results.

[0093] Step 52: Determine whether the current oil quality test result is less than the corresponding preset oil quality test target.

[0094] Once the current oil quality detection result is less than the corresponding preset oil quality detection target, step 53 is executed; otherwise, step 54 is executed.

[0095] Step 53: Control the filter assembly to perform a filtering operation on the mixture of the oil to be detected and the adsorbent.

[0096] That is to say, when the current oil quality test result is less than the corresponding preset oil quality test target, a filtering operation is performed on the mixture of the oil to be tested and the adsorbent, so as to separate the oil to be tested from the adsorbent. The separated oil to be tested can be stored in an oil storage tank for reuse.

[0097] Step 54 : Control the adsorbent assembly to provide an amount of adsorbent that matches the oil quality detection result, and control the mixing assembly to continue performing the mixing operation until the oil quality detection result of the mixing operation reaches the preset oil quality detection target.

[0098] That is to say, when the oil quality detection result is still greater than the corresponding preset oil quality detection target during the mixing operation, adsorbent can be added to the mixing tank again, and the mixing operation can be continued until the oil quality detection result of the mixing operation reaches the preset oil quality detection target.

[0099] It should be noted that the control component can obtain multiple oil quality test results during the mixing operation. Adsorbent is only added to the mixing tank when each of these multiple oil quality test results exceeds the corresponding preset oil quality test target. This multiple oil quality test results can prevent the control component's decision-making from being affected by insufficient mixing of the adsorbent and the oil to be tested, thereby improving control accuracy.

[0100] In practical applications, the control component can control the amount of adsorbent added based on the difference between the current oil quality test result and the preset oil quality test target, rather than adding a fixed amount each time. For example, if the difference between the current oil quality test result and the preset oil quality test target is large, the amount of adsorbent added can be increased, while if the difference is small, the amount of adsorbent added can be reduced. It is understood that the amount of adsorbent added corresponding to the current oil quality test result should be less than the initial amount of adsorbent added, thereby reducing adsorption costs.

[0101] In a specific implementation, after executing step 53, that is, controlling the filtering component to perform a filtering operation on the mixture of the oil to be tested and the adsorbent, the oil storage component can also be controlled to store the oil to be tested after the filtering operation is completed, and the adsorbent separated by the filtering component is stored in the filter.

[0102] The above scheme can not only filter the edible oil efficiently, but also reduce the filtering cost.

[0103] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
