Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically a rapid food extraction device. Background Technology

[0002] In the field of food testing and processing, rapid food extraction devices are increasingly widely used, aiming to efficiently obtain target components to meet analytical and production needs. Food extraction separates target analytes from complex food matrices for subsequent detection and analysis.

[0003] However, many current rapid food extraction devices have significant shortcomings when dealing with food samples with complex matrices. Food samples are extremely complex in composition, containing not only conventional components such as proteins, fats, and fibers, but also various micronutrients, additives, and potentially harmful substances. The interactions between different components form complex systems that some extraction devices struggle to adapt to effectively. In particular, when processing oil-rich foods (such as fried foods, meat products, and baked oil products), the oil easily adheres to the inner walls of the extraction device.

[0004] In existing technologies, traditional cleaning methods require disassembling parts and soaking and scrubbing the inner walls, which is cumbersome and time-consuming, greatly affecting work efficiency. These methods are also labor-intensive and can easily damage the equipment. While chemical cleaning can dissolve grease, there is a risk of chemical residue, threatening food safety. With the food industry's increasing demand for rapid and precise extraction, innovative technologies are urgently needed to solve the problem of grease adhesion in complex matrices. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid food extraction device to solve the problem mentioned in the background art where grease easily adheres to the inner wall of the food extraction filter cylinder. Traditional cleaning methods require disassembling parts and soaking and scrubbing the inner wall, which is cumbersome and time-consuming, greatly affecting work efficiency. It is also time-consuming, labor-intensive, and can easily damage the device. Although chemical cleaning can dissolve grease, there is a risk of chemical reagent residue, which threatens food safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid food extraction device includes a filter cylinder for rapid food extraction and filtration. The filter cylinder includes a first filter cylinder body and a cleaning cylinder body sleeved outside the first filter cylinder body. An inner wall cleaning component for cleaning grease on the inner wall of the first filter cylinder body is provided between the first filter cylinder body and the cleaning cylinder body.

[0008] The first filter cylinder has an I-shaped structure with a hollow interior and open sides. An grease discharge valve is integrally connected to the bottom of the first filter cylinder.

[0009] Preferably, the inner wall cleaning assembly includes a cleaning ramp pipe, a magnetic fluid, a coil, and a conveying component for conveying the magnetic fluid. The cleaning ramp pipe is distributed in a spiral structure on the outer circumferential wall of the first filter cylinder. The coil is distributed on the outer circumferential wall of the cleaning ramp pipe on the inner wall of the cleaning cylinder. The coil is electrically connected to an external controller via a wire.

[0010] Preferably, the conveying component includes a conveying pump and a magnetic fluid mixture. The magnetic fluid mixture is connected to the inlet of the conveying pump via a pipeline. The outlet of the conveying pump is connected to the top of the cleaning ramp pipe. The outlet of the cleaning ramp pipe is connected to an external magnetic fluid mixture pool.

[0011] Preferably, the first filter cylinder and the cleaning cylinder are made of stainless steel 316.

[0012] Preferably, the inner circumferential wall of the first filter cartridge is coated with a superhydrophobic material layer that reduces grease adhesion.

[0013] Preferably, the spiral angle of the cleaning ramp pipe is 15°-30° and the pitch is 5-10mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application achieves effective cleaning of the grease on the inner wall of the filter cylinder by setting a spirally distributed cleaning ramp pipe on the outer circumferential wall of the first filter cylinder, and by using a coil to generate a magnetic field to magnetize the magnetic fluid, and by controlling the current to form a magnetic field gradient along the spiral direction, driving the magnetic fluid to flow spirally downward along the ramp. The magnetic field can penetrate the cylinder wall of the first filter cylinder and act on the grease on the inner wall, thereby scraping off the grease and discharging it through the grease discharge valve at the bottom.

[0016] 2. The Joule heat generated by the electromagnetic coil can be conducted through the cylinder wall, raising the temperature of the inner wall and reducing the viscosity of the grease. This helps the grease to be more easily peeled off from the inner wall of the filter cylinder, further improving the cleaning effect.

[0017] 3. The first filter cylinder and the cleaning cylinder are made of 316 stainless steel, which has good corrosion resistance and strength. Stainless steel reduces the magnetic field shielding effect and ensures that the magnetic field can effectively penetrate the cylinder wall. At the same time, the inner circumferential wall of the first filter cylinder is coated with a superhydrophobic material layer, which can reduce the adhesion of grease. Combined with the cleaning effect of magnetic fluid, it better ensures the cleanliness of the filter cylinder and the efficiency and quality of food extraction.

[0018] 4. The design of the spiral angle and pitch of the cleaning ramp pipe is conducive to the formation of a stable spiral flow of the magnetic fluid inside the pipe, ensuring the driving effect of the magnetic field on the magnetic fluid and the effect of the grease on the inner wall.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0027] Please see the appendix Figure 1-5As shown, a rapid food extraction device includes a filter cylinder 1 for rapid food extraction and filtration. The filter cylinder 1 includes a first filter body 11 and a cleaning cylinder 12 sleeved outside the first filter body 11. The first filter body 11 and the cleaning cylinder 12 are made of food-grade stainless steel 316. This material has excellent corrosion resistance and can effectively resist the erosion of various acids and alkalis during food extraction, preventing chemical reactions between the material and the food and ensuring food safety. At the same time, 316 stainless steel reduces the magnetic field shielding effect, ensuring that the magnetic field can effectively penetrate the cylinder wall and guarantee the operation of the inner wall cleaning components. The first filter body 11 is I-shaped with an internal hollow structure and open sides. The structural design provides ample space for the extraction and filtration of food samples, allowing them to pass through smoothly and reducing residue. The bottom of the first filter cylinder 11 is integrally connected with an oil discharge valve 13, which, together with the inner wall cleaning function, can promptly discharge the cleaned oil, preventing oil accumulation inside the cylinder and ensuring the continuity of the extraction process. The inner circumferential wall of the first filter cylinder 11 is coated with a superhydrophobic material layer that reduces oil adhesion. The superhydrophobic material layer is a silica nanoparticle layer, which has good superhydrophobicity, a certain degree of wear resistance and chemical stability, and can resist the erosion of various chemical substances during food extraction, ensuring the long-term stability of superhydrophobic performance.

[0028] Food samples enter from one end of the first filter cylinder 11. Under the action of gravity, the samples pass through the filter structure. The target components are collected through the filter holes on the cylinder wall, while impurities, grease, and other substances adhere to the inner wall of the first filter cylinder 11. The control equipment starts the inner wall cleaning component to clean the grease adhering to the inner wall of the first filter cylinder 11 and discharge it through the grease discharge valve 13 at the bottom. The automatic cleaning function of this application reduces the frequency of manual disassembly and cleaning, and reduces labor intensity. The stainless steel material and reasonable structural design extend the service life of the equipment and reduce maintenance and replacement costs.

[0029] Please see the appendix Figure 1 , 3As shown in Figures 4 and 5, an inner wall cleaning assembly is provided between the first filter cylinder 11 and the cleaning cylinder 12 for cleaning grease on the inner wall of the first filter cylinder 11. The inner wall cleaning assembly consists of four main components: a cleaning ramp pipe 2, a magnetic fluid 21, a coil 22, and a conveying component. Through structural design and electromagnetic control, automated and precise grease cleaning is achieved. The cleaning ramp pipe 2 is arranged in a spiral structure on the outer circumferential wall of the first filter cylinder 11, with a spiral angle of 15°-30° and a travel distance of 5-10mm. The helical pitch surrounds the outer circumferential wall of the first filter cylinder 11. The helical angle ensures that the magnetic fluid generates a stable tangential force during flow. The pitch setting ensures the contact frequency between the magnetic fluid and the cylinder wall, avoiding blind spots caused by excessive spacing, while preventing a surge in fluid resistance caused by insufficient spacing. This helical structure not only provides a directional flow path for the magnetic fluid, but also extends the flow trajectory, allowing the magnetic fluid to penetrate and fully contact the inner wall, thus improving cleaning efficiency. The coils 22 are distributed on the outer circumferential wall of the cleaning ramp pipe 2 on the inner wall of the cleaning cylinder 12. The coils 22 are electrically connected to an external controller through wires. By controlling the magnitude and direction of the coil current, the magnetic field strength and direction can be adjusted in real time, forming a dynamic magnetic field gradient along the helical ramp. This design breaks through the traditional static cleaning mode, enabling the magnetic fluid to flexibly adjust its flow speed and intensity according to the grease adhesion under the drive of a magnetic field, achieving "on-demand cleaning". The conveying components include a delivery pump and a magnetic fluid mixture. The magnetic fluid mixture is connected to the inlet of the delivery pump through a pipeline, and the outlet of the delivery pump is connected to the top of the cleaning ramp pipe 2. The outlet of the cleaning ramp pipe 2 is connected to an external magnetic fluid mixture pool. After the spiral ramp completes the cleaning task, it flows back to the external magnetic fluid mixture pool through the outlet. This circulation design avoids magnetic fluid waste and reduces usage costs. On the other hand, by replenishing and updating the magnetic fluid in real time, it ensures its cleaning activity. Compared with the single-use mode, the consumption of magnetic fluid is reduced.

[0030] During operation, food samples enter the first filter cylinder 11. During the filtration process, grease gradually adheres to the inner wall of the cylinder. At this time, the cleaning component is in standby mode, the delivery pump stops working, the coil is de-energized, and the magnetic fluid remains still in the mixing tank. During cleaning, the delivery pump starts running, injecting the magnetic fluid mixture into the top of the cleaning ramp pipe 2. At the same time, the coil 22 is energized, generating a magnetic field along the spiral direction, magnetizing the magnetic fluid inside the tube. Under the guidance of the magnetic field force and the spiral ramp, the magnetic fluid flows spirally downward along the outer wall of the cylinder. During this process, the magnetic fluid cleans the grease through two mechanisms: First, the magnetic field of the magnetic fluid penetrates the cylinder wall, adsorbing magnetic impurities in the grease and cleaning them. During cleaning, the magnetic fluid moves inside the cleaning ramp pipe 2, driving the grease towards the grease discharge valve 13. Second, the Joule heat generated by the electromagnetic coil is conducted through the cylinder wall, reducing the viscosity of the grease and making it easier to be washed away. The cleaned grease slides down with the magnetic fluid to the bottom of the filter cylinder and is discharged through the grease discharge valve 13. After cleaning, the magnetic fluid flows back to the mixing tank through the outlet of the cleaning ramp pipe 2. Through a magnetic filter or centrifugal separator, the magnetic fluid and grease are separated. The magnetic fluid can participate in the cleaning work again, forming a sustainable cleaning cycle.

[0031] The inner wall cleaning component of this application is disposed between the first filter cylinder 11 and the cleaning cylinder 12. The magnetic fluid flows in the cleaning ramp pipe 2 and acts on the grease through the magnetic field penetrating the cylinder wall. It does not need to directly contact the food inside the filter cylinder. This non-contact cleaning method fundamentally eliminates the risk of food contamination by the cleaning medium (magnetic fluid, coil and other components), avoids the introduction of impurities and chemicals during the cleaning process that may affect the food composition and quality, and ensures that the extracted food components are pure and safe, meeting the strict hygiene and quality standards of the food industry. It is particularly suitable for food testing and high-end food processing scenarios with extremely high safety requirements.

[0032] Furthermore, during the cleaning process, the food extraction and filtration work inside the first filter cylinder 11 is not affected and can continue to operate normally. The start-up and operation of the cleaning components are precisely controlled by an external controller. When cleaning is required, the delivery pump and coil start working, and the magnetic fluid performs spiral flow cleaning in the external cleaning ramp pipe 2, which is completely separated from the food flow path inside the filter cylinder. This allows the device to complete the cleaning of the inner wall grease without stopping the machine during continuous production, which significantly improves production efficiency and reduces the time wasted and production interruption caused by stopping the machine for cleaning.

[0033] Furthermore, traditional cleaning methods, such as manual scrubbing or chemical cleaning, can easily cause wear and corrosion to the inner wall of the filter cartridge due to frequent operation, shortening the equipment's service life. This device, however, uses magnetic fluid non-contact cleaning, which gently removes grease through magnetic force and thermal effects without causing any physical damage to the material and structure of the filter cartridge's inner wall. Simultaneously, the application of a superhydrophobic material layer further reduces direct contact and adhesion between grease and the inner wall, lowering the difficulty and frequency of cleaning. The combination of these two methods effectively protects the integrity of the filter cartridge, extends its service life, and reduces equipment replacement costs.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
