Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to storage tanks, as well as a continuous pre-filling and mixing system and process method having storage tanks. Background Technology

[0002] In the food industry, especially in the production of seasonings and edible oils, the separation and bottling of oil-residue mixtures is a crucial process. Traditional oil-residue separation technologies mainly employ methods such as static sedimentation, centrifugation, or multi-stage filtration to separate the oil from the residue.

[0003] In existing technologies, filling equipment is mainly used for filling single liquids or sauces. For products that require "filling first, then oil," the common practice is to use a "dry residue filling - weighing - oil filling" model because oil residue needs to be quantitatively controlled separately. First, the oil residue needs to be completely separated beforehand and then filled into the target containers, a cumbersome process that increases pre-processing costs. Second, it relies heavily on manual operation, requiring a large number of people for quantitative weighing, resulting in high labor intensity. Third, production continuity is poor; the filling speed cannot keep up with increasing market demand, hindering capacity expansion. Finally, the traditional process is inefficient, with issues of transfer losses and time-consuming steps. These problems affect production efficiency and product quality stability, making it difficult to meet the requirements of modern food industry for continuous and automated production. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a storage cylinder that has the advantages of compact structure and integrated functions.

[0005] The present invention also proposes a continuous pre-filling and mixing system and process method having the above-mentioned storage tank.

[0006] The storage tank according to the present invention comprises: The cylinder body is provided with a feed inlet and an oil residue discharge outlet. A filter element is fixedly installed inside the cylinder body, and the filter element is used to separate the oil from the residue in the oil-sludge mixture. The oil residue outlet is located at the bottom of the cylinder body, and the bottom of the cylinder body has an inclined structure to guide the material flow to the oil residue outlet.

[0007] The storage tank according to the present invention has at least the following beneficial effects: By fixing a filter element inside the tank, in-situ separation and storage of the oil-sludge mixture are integrated, eliminating the need to transfer the material to a separate separation device, thus simplifying the equipment layout and process flow. Simultaneously, the inclined structure at the bottom of the tank allows gravity to guide the material automatically to the oil-sludge outlet, avoiding the residue accumulation common in flat-bottomed containers, ensuring smooth discharge, and improving filling continuity and production efficiency. The fixed installation of the filter element allows for automatic solid-liquid separation of the oil-sludge mixture upon entering the tank. The separated sludge is temporarily stored inside the tank, while the oil can be separated from the sludge through the filter element, creating conditions for subsequent processes. Since the separation process is completed in-situ within the tank, losses and contamination risks during material transfer are avoided. Furthermore, the compact structure and integrated functions of the tank adapt to continuous production needs, significantly reducing labor intensity and improving overall operational efficiency.

[0008] According to some embodiments of the present invention, the inclined structure of the storage tank includes at least one inclined slope that is inclined toward one side of the oil residue outlet.

[0009] According to some embodiments of the present invention, the inclined angle of the inclined surface of the storage cylinder is α, where 5°≤α≤30°.

[0010] According to some embodiments of the present invention, the storage tank has two filter elements, which are spaced apart in the tank body.

[0011] According to some embodiments of the present invention, the storage cylinder includes a first filter cylinder and a second filter cylinder, wherein the first filter cylinder is sleeved on the outside of the second filter cylinder, and the filter pore diameter of the first filter cylinder is larger than that of the second filter cylinder.

[0012] According to some embodiments of the present invention, a porous filter plate with a mesh size of 50 is fixedly disposed on the side wall of the second filter cylinder, and a porous plate with a pore diameter of 2mm is fixedly disposed on the side wall of the first filter cylinder.

[0013] The continuous pre-filling and mixing system according to the present invention includes a storage tank as described in the present invention, and further includes a cooking device, a conveying device, a filling machine, and an oil replenishing device. The cooking device is used to prepare an oil-residue mixture. The conveying device is connected to the outlet of the cooking device, and the inlet is connected to the output end of the conveying device. The storage tank is provided with an oil outlet. The filling machine is connected to the oil-residue outlet of the storage tank. The oil replenishing device is connected to the oil outlet and is used to quantitatively store the separated oil and replenish it into the container.

[0014] The continuous pre-filling and mixing system according to the present invention has at least the following beneficial effects: By integrating the cooking equipment, conveying device, storage tank, filling machine, and oil replenishment device, a fully continuous production line from raw material processing to finished product filling is constructed. The oil-sludge mixture prepared by the cooking equipment is directly pumped into the storage tank via the conveying device. In the tank, the oil and sludge are physically separated immediately through a filter, eliminating the need for separate centrifuge or sedimentation equipment and completely breaking the traditional process of "separation first, storage then filling". The separated oily sludge is temporarily stored at the bottom of the tank and, due to the guiding effect of the inclined structure, can be smoothly conveyed to the filling machine for filling. Simultaneously, the separated oil enters the oil replenishment device for quantitative storage through the oil outlet, and is precisely replenished into the same container after the sludge is filled. This achieves automated production of "cooking – conveying – separation – filling – oil replenishment", maintaining suitable fluidity of the oily sludge and effectively avoiding the risk of dry sludge clogging the pipeline.

[0015] According to some embodiments of the present invention, the continuous pre-filling and mixing system includes a conveying device comprising a diaphragm pump and a conveying pipeline. The input end of the diaphragm pump is connected to the outlet of the cooking equipment, and the output end of the diaphragm pump is connected to the inlet. The storage cylinder is connected to the filling machine through the conveying pipeline. The oil replenishment device includes an oil supply pipe and an oil inlet machine. One end of the oil supply pipe is connected to the oil outlet, and the other end is connected to the oil inlet machine.

[0016] The process method according to the present invention includes using the storage cylinder described in the present invention, and includes the following steps: The mixture of cooked oil residue is conveyed to the storage tank. Separation: The oil-sludge mixture is separated into solid and liquid components by a filter element in the storage tank to obtain oil and oil-containing sludge. Pre-extraction: A predetermined mass of the oil is extracted from the oil outlet of the storage tank and stored as spare oil. Filling: The residue mixed with the remaining oil in the storage tank is conveyed to the filling machine through the oil residue outlet and filled into the target container. Replenishing oil involves adding the spare oil into the target container that has already been filled with slag material using an oil replenishment device.

[0017] According to the process method described in this invention, at least the following beneficial effects are achieved: By directly conveying the cooked oil-residue mixture to a storage tank for in-situ separation, the entire process of "cooking – conveying – separation – filling – oil replenishment" is integrated and continuous, avoiding the cumbersome procedures of complete separation and multiple transfers required in traditional processes. This method uses a "pre-extraction" step to separate and store a portion of the oil in advance, while the remaining oil-containing residue is directly filled while maintaining suitable fluidity. This not only meets the "residue first, oil later" product filling requirement but also effectively avoids the risk of dry residue clogging the pipeline. Finally, the "oil replenishment" step quantitatively replenishes the reserved oil into the container, ensuring precise and controllable oil-residue ratio. Some experiments show that this method increases the filling speed of 1kg product from 400EA / H to 700EA / H and 7kg product from 150EA / H to 300EA / H, significantly improving production efficiency. Simultaneously, the fully automated operation greatly reduces manual intervention, ensuring the stability and consistency of product quality.

[0018] According to some embodiments of the present invention, the mass of the residue in the oil-containing residue material accounts for 50%, the mass of the oil in the oil-containing residue material accounts for 20%, and the mass of the spare oil accounts for 30%.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0025] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0026] In the description of this invention, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] Currently, mainstream filling equipment in the market is mainly used for filling single liquids or sauces. For products that require "filling first and then oiling," such as oil-infused sauces and oil residue mixed seasonings, a separate operation mode of "dry residue filling, weighing, and oiling" is generally adopted because the oil residue needs to be quantitatively controlled separately. However, in existing technologies, on the one hand, oil residue separation and storage are usually completed by two independent devices. The cooked oil residue mixture must first be transferred to the separation device for complete separation, and then the separated dry residue is transferred to a storage container for temporary storage. The equipment layout is scattered, occupies a large area, and the process connection is not smooth, resulting in increased pre-processing costs. On the other hand, traditional storage containers are mostly flat-bottomed structures, and manual assistance is required to push or tilt the container when discharging. It is impossible to achieve gravity discharge of materials. Especially for oil residue mixtures with high viscosity, residue is easily formed at the bottom of the container, resulting in poor discharge and affecting the continuity of filling. In addition, existing separation equipment mostly adopts static sedimentation or manual filtration, which takes a long time to separate and requires frequent manual intervention for quantitative weighing. This results in high labor intensity and high dependence on manual labor, making it impossible to achieve synchronous transportation and in-situ separation of oil-sludge mixtures, thus limiting production cycle and restricting capacity improvement.

[0028] Therefore, such as Figures 1 to 3 As shown, the storage tank proposed in this invention includes a tank body 100 and a filter element 200. The tank body 100 has a rectangular structure and is provided with an inlet 110 and an oil residue outlet 120. The inlet 110 is located at the top of the tank body 100 and is used to receive the oil residue mixture from the conveying device. The oil residue outlet 120 is located at the bottom of the tank body 100 and is used to output the separated oil residue mixture. The bottom of the tank body 100 adopts an inclined structure design, which can effectively guide the material flow to the oil residue outlet 120, avoid residue accumulation at the bottom, and ensure smooth discharge. By fixing the filter element 200 inside the tank body 100, the in-situ separation and storage of the oil residue mixture are integrated, eliminating the need to transfer the material to a separate separation device, simplifying the equipment layout and process flow. Meanwhile, the inclined structure at the bottom of the cylinder 100 allows gravity to guide the material automatically to the oil residue outlet 120, avoiding the residue buildup common in flat-bottomed containers, ensuring smooth discharge, and improving filling continuity and production efficiency. The fixed arrangement of the filter element 200 enables automatic solid-liquid separation of the oil-residue mixture upon entering the cylinder 100. The separated residue is temporarily stored inside the cylinder, while the oil can be separated from the residue through the filter element 200, creating conditions for subsequent processes. Because the separation process is completed in situ within the cylinder, losses and contamination risks during material transfer are avoided. Furthermore, the compact structure and integrated functions of the cylinder 100 adapt to continuous production needs, significantly reducing labor intensity and improving overall operational efficiency.

[0029] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the inclined structure at the bottom of the cylinder 100 includes at least one inclined surface 140, which slopes towards the oil residue outlet 120. Utilizing gravity, the oil residue mixture flows naturally towards the outlet, improving the system's continuity and automation. The inclination angle of the inclined surface 140 is α, controlled within the range of 5° ≤ α ≤ 30°. When the inclination angle is less than 5°, the guiding effect is not significant, and the material easily accumulates at the bottom; when the inclination angle is greater than 30°, the material flows too quickly, hindering thorough separation. In a preferred embodiment, the inclination angle can be set to 15°, ensuring both good guiding effect and sufficient separation.

[0030] In some embodiments of the present invention, reference is made to 1 to Figure 3 The filter element 200 is fixedly installed inside the cylinder body 100 to separate the oil from the sludge in the oil-sludge mixture. Multiple handles 210 are provided on the side wall of the filter element 200 for easy lifting and removal from the cylinder body 100 by the operator. Two filter elements 200 are configured, spaced apart inside the cylinder body 100 to improve separation efficiency and accuracy. Each filter element 200 includes a first filter cylinder 220 and a second filter cylinder 230, with the first filter cylinder 220 sleeved over the second filter cylinder 230 to form a double-layer filtration structure. The pore size of the first filter cylinder 220 is larger than that of the second filter cylinder 230, achieving a gradient separation process from coarse filtration to fine filtration.

[0031] In some embodiments of the present invention, reference is made to... Figure 2 In terms of specific filtration parameter settings, a porous filter plate 231 with a mesh size of 50 is fixedly installed on the side wall of the second filter cylinder 230, which can effectively block fine slag particles and only allow oil to pass through. A porous plate 221 with a pore size of 2mm is fixedly installed on the side wall of the first filter cylinder 220, which is mainly used to intercept larger slag particles for preliminary separation. The double-layer filtration helps to ensure efficient physical separation of oil and slag. The separated oil is extracted through a dedicated oil outlet 130, while the slag flows to the oil slag outlet 120 under the guidance of gravity and the inclined structure.

[0032] In related technologies, the storage tank lacks an insulation structure, which easily leads to temperature loss during oil storage and separation, causing the oil viscosity to increase. This not only reduces filtration and separation efficiency but also increases material transport resistance, easily causing blockages in pipes and interfaces. Furthermore, the interfaces of existing storage tanks lack unified industrial standards, the material selection does not take into account both food contact safety and structural strength for industrial production, and the accessories have poor compatibility with workshop conveying equipment, further restricting the continuity and automation level of production.

[0033] Furthermore, in some embodiments of the present invention, reference is made to... Figures 1 to 3The cylinder body 100 is made of food-grade 304 stainless steel with a double-layer insulation structure. The double-layer insulation structure of the cylinder body 100 is a stainless steel jacket structure, and the inside of the jacket is filled with food-grade insulation medium. All interfaces and accessories are insulated. The cylinder body 100 is made of 304 stainless steel plates of different specifications. The main body of the cylinder body 100 is made of 1200×1040×7mm or 1300×1200×2mm 304 stainless steel plates. The internal guide inclined surface 140 and the filter element 200 are made of 1200×1000×2mm or 100×100×2mm 304 stainless steel plates. All interface accessories are made of 304 stainless steel derivative materials of specifications 304 / 18, 304 / 78, and 304 / 84. The side wall of the first filter cylinder 220 is fixedly provided with a 304 stainless steel porous plate 221 with a hole diameter of 2mm, and the side wall of the second filter cylinder 230 is fixedly provided with a 304 stainless steel porous filter plate 231 with a mesh size of 50. The filter element 200 is a fixed installation structure, which is welded or snap-fitted to the inside of the cylinder 100 to ensure the sealing and heat preservation effect of the cylinder 100.

[0034] The continuous pre-filling and mixing system according to an embodiment of the present invention includes a storage tank according to an embodiment of the present invention. It also includes a cooking device, a conveying device, a storage tank, a filling machine, and an oil replenishment device. The cooking device is used to prepare an oil-residue mixture, providing raw materials for the entire system. The conveying device is connected to the outlet of the cooking device and is responsible for conveying the prepared oil-residue mixture to the storage tank. The storage tank serves as a separation and temporary storage component of the system. The filling machine is connected to the oil-residue outlet 120 of the storage tank, and the oil replenishment device is connected to the oil outlet 130 of the storage tank for quantitatively storing and replenishing the separated oil into the container.

[0035] According to an embodiment of the present invention, the continuous pre-filling and mixing system integrates the cooking equipment, conveying device, storage tank, filling machine, and oil replenishment device to construct a fully continuous production line from raw material processing to finished product filling. The oil-residue mixture prepared by the cooking equipment is directly pumped into the storage tank via the conveying device. Within the tank, the oil and residue are physically separated instantly by the filter element 200, eliminating the need for separate centrifuges or sedimentation equipment and completely breaking away from the traditional process of "separation first, storage then filling." The separated oily residue is temporarily stored at the bottom of the tank 100. Due to the guiding effect of the inclined structure, it can be smoothly conveyed to the filling machine for filling. Simultaneously, the separated oil enters the oil replenishment device for quantitative storage through the oil outlet 130, and is precisely replenished into the same container after the residue filling is completed. This achieves automated production of "cooking – conveying – separation – filling – oil replenishment," maintaining suitable fluidity of the oily residue and effectively avoiding the risk of dry residue clogging the pipeline.

[0036] In a further embodiment of the invention (not shown in the figures), the conveying device includes two main components: a diaphragm pump and a conveying pipeline. The input end of the diaphragm pump is connected to the discharge port of the cooking equipment, and the output end is connected to the inlet 110 of the storage tank, enabling the simultaneous pumping of the cooked oil-sludge mixture into the storage tank. The diaphragm pump adopts the principle of volumetric conveying, generating suction and pressure through the reciprocating motion of the diaphragm to achieve continuous conveying of the oil-sludge mixture, making it particularly suitable for conveying viscous materials containing solid particles. The storage tank is connected to the filling machine through the conveying pipeline, forming a complete conveying chain from cooking to filling.

[0037] The working principle of the entire continuous pre-filling and mixing system is as follows: The oil-residue mixture prepared by the cooking equipment is pumped to the inlet 110 of the storage tank by a diaphragm pump. The mixture undergoes separation treatment by a double-layer filter element 200 within the storage tank. The oil flows through the filter element 200 into the oil outlet 130 and is then transported to the oil filling machine for storage and standby. The remaining oil-containing residue flows to the oil-residue outlet 120 under the guidance of an inclined structure and is transported to the filling machine for filling via a conveying pipeline. Based on the total mass of the final filled product, the residue mass in the oil-containing residue accounts for 50%, the oil mass accounts for 20%, and the reserved oil mass accounts for 30%. After filling, the oil filling machine precisely replenishes the reserved 30% oil into the container already filled with residue, completing the "residue first, oil later" full-process filling operation. The continuous pre-filling and blending system integrates storage, separation, and conveying functions, breaking through the traditional "separate first, then fill" process and forming a closed-loop continuous production process of "cooking – conveying – separation – pre-extraction – filling – oil replenishment". By maintaining a 20% oil content in the slag, the system improves the fluidity of the slag during filling, avoids dry slag blockage, and ensures the quality requirements of the final product, significantly improving production efficiency and automation.

[0038] Reference Figure 4According to the process method of this embodiment of the invention, a storage tank according to this embodiment of the invention is used. The process also includes the following steps: Conveying: The oil-sludge mixture after cooking is drawn from the outlet of the cooking equipment using a diaphragm pump and conveyed to the storage tank via a dedicated conveying pipeline. The storage tank has a square structure, with an inlet 110 at the top and an oil-sludge outlet 120 at the bottom. The bottom of the tank 100 adopts an inclined structure design, including at least one inclined slope 140, which is inclined towards the oil-sludge outlet 120 at an angle of 15°, effectively guiding the material flow to the oil-sludge outlet 120 and preventing residue accumulation. Separation: The oil and sludge are physically separated in the storage tank using a filter element 200. The filter element 200 consists of two elongated square filter screens, spaced apart inside the tank 100. The pore size of the filter screens precisely matches the size of the product sludge particles, allowing only oil to pass through. The oil automatically flows into the filter screen under gravity and is discharged from the oil outlet 130 through a dedicated oil delivery pipe connected to the filter screen. Pre-extraction: Of the total separated oil, 30% is extracted through a dedicated oil delivery pipe to the oil inlet machine for storage and later use in the replenishment process, ensuring precise oil metering. Filling: The remaining oil-sludge mixture in the storage tank is guided by the inclined bottom structure and pumped through the oil sludge outlet 120 to the filling machine via a conveying pipe for precise filling into the target container. Replenishment: The oil inlet machine is then started, and the reserved 30% of oil is meteredly added to the container already filled with sludge through the replenishment device, completing the "sludge first, oil later" filling process.

[0039] In some embodiments, the inclination angle of the inclined slope 140 at the bottom of the storage cylinder can be set in the range of 5° to 30°, and the most suitable angle can be selected according to the characteristics of different materials to optimize the material flow effect.

[0040] According to the process method of this invention, by employing the storage tank of this invention, integrated continuous production of "cooking - conveying - separation - pre-extraction - filling - oil replenishment" is achieved, eliminating the need for additional oil residue separation processes and significantly improving production efficiency. Automated operation reduces labor intensity and significantly increases production speed; for example, 1kg product output increases from 400EA / Hr to 700EA / Hr, and 7kg product output increases from 150EA / Hr to 300EA / Hr, effectively meeting incremental market demand.

[0041] Other configurations and operations of the continuous pre-filling and mixing system and process according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
