Description

TECHNICAL FIELD

[0001] The utility model relates to food processing technical field, concretely relates to multistage oil separation device. BACKGROUND

[0002] As a popular food, the production scale of hot pot condiment is also increasing. In the existing hot pot condiment production process, in order to give hot pot condiment rich and mellow flavor, frying with oil is an essential link. In the frying process, various spices such as chili, star anise, cassia bark and pepper are fully mixed with oil to form a unique flavor. However, after frying is completed, oil and material need to be separated for subsequent processing and packaging.

[0003] At present, there are many related technical solutions disclosed. For example, patent announcement No. CN205455873U, a kind of automatic production line of beef tallow hot pot condiment, which sends the finished condiment into a steaming tank first, then from the steaming tank into a separator, and the separated residue is discharged from the residue discharge channel, while the oil is directly pumped into the filling machine. In addition, patent publication No. CN117256893A, a kind of hot pot condiment frying equipment and its process, also sends the fried condiment into a separation device for solid-liquid separation, and after separation, it is transferred into a solid material tank and an oil tank for temporary storage (the oil tank for temporarily storing oil is also called oil storage tank in this paper), and then it is filled and packaged by a filling and packaging equipment.

[0004] However, these existing production methods have obvious disadvantages. When hot pot condiment is separated, although it has gone through the solid-liquid separation step of the separation equipment, there will still be a large amount of small size / small particle residue in the oil. If these residues are not further filtered and directly sent to the oil storage tank, there will be more residue on the pipeline leading to the oil storage tank and in the oil storage tank. The residue on the pipeline can easily reduce the smoothness of the pipeline, which may cause higher energy consumption of the pump body to send the same amount of oil into the storage tank, increasing energy consumption, or even cause blockage. Similarly, the residue in the oil storage tank can also cause pipeline blockage when pumped to the filling and packaging machine. In addition, the presence of more residue in the oil storage tank when oil is pumped to the filling and packaging machine can cause large fluctuations in the oil content of the oil liquid (the residue will sink to the bottom in the resting state when the oil storage tank is temporarily stopped to output raw materials to the subsequent process, and the lower or bottom layer of raw materials is pumped out first when pumping, so that the residue content in the oil liquid pumped out at the beginning of each use of the oil storage tank is higher, resulting in fluctuations in the oil content of the oil liquid sent out), ultimately causing fluctuations in the oil content and spice content of the hot pot condiment after filling, affecting the consistency of product quality. In addition, the residue deposited on the pipeline may deteriorate due to the special ingredients and production environment of hot pot condiment, thereby affecting the quality of hot pot condiment and reducing the taste and safety of the product. The utility model discloses a multistage oil separation device, which is used for separating the oil liquid separated by a solid-liquid separation device.

[0005] The utility model discloses a multistage oil separation device, which is used for separating the oil liquid separated by a solid-liquid separation device.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] The multistage oil separation device is used for re-filtering the oil liquid separated by the solid-liquid separation device, and includes a separation vehicle, a first filter, an oil storage tank and a second filter which are sequentially connected. The oil outlet end of the first filter is connected to the oil storage tank, and the oil outlet end of the second filter is used for connecting to a filling packaging machine. The separation vehicle includes a feeding accommodating cavity and a discharging accommodating cavity. The oil separated by the solid-liquid separation device falls into the feeding accommodating cavity. The feeding accommodating cavity and the discharging accommodating cavity are connected through a metal filter screen. The discharging accommodating cavity is connected to a liquid outlet pipe, and the liquid outlet pipe is connected to the first filter.

[0008] The principle and advantages of the present scheme are as follows: The oil and solid material separated from the solid-liquid separation device are not directly sent to the oil storage tank for storage, but first enter the feeding accommodating cavity of the separation vehicle. The oil is separated by the metal filter screen between the feeding accommodating cavity and the discharging accommodating cavity. The separated oil liquid is discharged from the liquid outlet pipe of the discharging accommodating cavity to the first filter. The filtered oil liquid is sent to the oil storage tank for storage after being filtered again by the first filter.

[0009] Since the oil storage tank does not supply oil liquid to the subsequent process at all times, small particles of residue inevitably exist in the oil liquid. To avoid the influence of the residue contained in the oil liquid in the oil storage tank on the subsequent pumping, the second filter is arranged to perform the last filtration on the oil liquid. Therefore, the oil liquid sent to the filling packaging machine is ensured to have higher purity after being separated by the solid-liquid separation device and filtered by the multistage oil separation device through three-stage filtration. This helps to ensure the stability of the oil and spice ratio during the filling packaging stage and the consistency of product quality. In addition, the multistage filtration also reduces the probability of residue remaining in the pipeline, greatly reducing the probability of pipe blockage.

[0010] Preferably, as an improvement, the first filter and the second filter are both edible oil filters.

[0011] Preferably, as an improvement, a switch valve is connected between the liquid outlet pipe and the first filter. In this way, the oil liquid in the discharging accommodating cavity of the separation vehicle can be allowed to stand for a certain period of time before being sent to the first filter, so that the residue contained in the oil liquid sent by the separation vehicle is less.

[0012] Preferably, as an improvement, the first filter is connected to the switch valve through a male and female joint, facilitating the disconnection of the first filter and the separating vehicle when the separated sediment in the vehicle needs to be treated separately.

[0013] Preferably, as an improvement, a metal mesh is arranged on the feeding accommodating cavity, the metal mesh forms a downward arc-shaped recess in the feeding accommodating cavity, and the metal mesh is arranged higher than the metal filter screen, so that the arc-shaped recess facilitates manual collection of the sediment on the metal mesh when the sediment is too much.

[0014] Preferably, as an improvement, the mesh of the metal mesh is smaller than that of the metal filter screen.

[0015] The mesh of the metal mesh is finer than that of the metal filter screen, and the metal mesh is more flexible, so that most of the sediment can be filtered out through the metal mesh, and the probability of the sediment entering the discharging accommodating cavity is reduced. The metal filter screen is used to flow the filtered oil to the discharging accommodating cavity and reduce the disturbance of the newly entered oil to the existing oil, thereby helping the finer sediment that is not filtered to be precipitated in the separating vehicle.

[0016] Preferably, as an improvement, the top of the separating vehicle is open, and the top of the feeding accommodating cavity and the discharging accommodating cavity is open. The fried oil has a certain temperature when being separated by the solid-liquid separation device, and the open top of the separating vehicle is helpful for the cooling of the oil.

[0017] Preferably, as an improvement, the metal mesh is detachably connected to the top opening of the feeding accommodating cavity.

[0018] Preferably, as an improvement, a filter frame is hung in the separating vehicle, the top of the filter frame is open, the inner space of the filter frame forms the feeding accommodating cavity, and the filter screen is arranged around the filter frame.

[0019] Preferably, as an improvement, an upward protruding piece is fixed on each edge of the top end of the filter frame, the metal mesh is clamped on the protruding piece by using a clip to fix the metal mesh, the structure is simple, easy to realize, and convenient for disassembly and assembly of the metal mesh.

[0029] The first filter 200 and the second filter 400 are both the filters for filtering the filter residue of edible oil.
