Description

Technical Field

[0001] This utility model relates to the field of soy sauce production, specifically to a soy sauce oil separation tank. Background Technology

[0002] Soy sauce's main ingredients are soybeans and wheat. Since soybeans naturally contain a certain amount of oil, this oil is gradually released during the soy sauce brewing process as the soybeans decompose and ferment. If this oil is stored in soy sauce for a long time, it is prone to oxidation, producing rancid and other unpleasant odors that severely affect the soy sauce's flavor. Excessive oil also makes the soy sauce taste greasy. Furthermore, the presence of oil makes the soy sauce appear cloudy, affecting its transparency and visual appeal. In addition, oil is a good carbon source for microbial growth and reproduction; excessive oil residue in soy sauce increases the risk of microbial contamination, making it more susceptible to spoilage and decay during storage and transportation.

[0003] Therefore, in the soy sauce production process, it is usually necessary to separate the soy sauce and oil to reduce the possibility of microbial growth, extend the shelf life of the soy sauce, and minimize losses due to spoilage. Soy sauce with the oil separated can better meet relevant quality standards and ensure the stability and consistency of product quality.

[0004] In existing technologies, separation techniques such as static separation, centrifugal separation, and filtration are commonly used to separate oil from soy sauce. However, the processes involved in these separation methods are quite complicated and the oil separation is time-consuming, resulting in low efficiency and high cost in the actual production process of soy sauce. Utility Model Content

[0005] To address the above problems, this utility model provides a soy sauce oil separation tank, which can quickly and conveniently separate soy sauce and oil of different qualities, while also saving soy sauce production costs and improving soy sauce production efficiency to a certain extent.

[0006] This utility model provides a soy sauce oil separation tank, including a light-pressure oil tank, a heavy-pressure oil tank, an oil discharge chamber, a light-pressure oil discharge chamber, and a heavy-pressure oil discharge chamber. The light-pressure oil tank and the heavy-pressure oil tank are separated by a first partition, the top of which is lower than the other side walls of the light-pressure oil tank. The oil discharge chamber and the heavy-pressure oil tank are separated by a second partition, the top of which is lower than the other side walls of the heavy-pressure oil tank. A first connecting pipe is provided in the light-pressure oil discharge chamber, its first lower port connecting to the bottom of the light-pressure oil tank, and its first upper port extending to a position corresponding to and higher than the top of the first partition. A second connecting pipe is provided in the heavy-pressure oil discharge chamber, its second lower port connecting to the bottom of the heavy-pressure oil tank, and its second upper port extending to a position corresponding to and higher than the top of the second partition.

[0007] Optionally, a light pressure oil inlet is provided above the light pressure oil tank, and a heavy pressure oil inlet is provided above the heavy pressure oil tank.

[0008] Optionally, the first upper port of the first connecting pipe is a height-adjustable threaded head.

[0009] Optionally, the second upper port of the second connecting pipe is a height-adjustable threaded head.

[0010] Optionally, the inner walls of the grease discharge chamber, the light pressure oil discharge chamber, and the heavy pressure oil discharge chamber all have a horizontal cross-sectional area that gradually decreases from top to bottom.

[0011] Optionally, the bottom of the grease discharge chamber, the light pressure oil discharge chamber, and the heavy pressure oil discharge chamber are all provided with discharge ports.

[0012] Optionally, the height of the first upper port is 5mm-10mm higher than the height of the top of the first partition.

[0013] Optionally, the height of the second upper port is 5mm-10mm higher than the height of the top of the second partition.

[0014] The soy sauce oil separator provided by this invention allows for the simultaneous injection of light-pressed oil and heavy-pressed oil produced during the soy sauce brewing process into the light-pressed oil tank and heavy-pressed oil tank, respectively. Utilizing the density difference between soy sauce and oil, the two are naturally separated into layers under gravity. Furthermore, by using connecting pipes and baffles with a specific height difference between them within the soy sauce oil separator, the separated soy sauce and oil can be quickly and conveniently separated at a low cost, thereby improving the production quality and efficiency of soy sauce.

Detailed Implementation

[0018] 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.

[0019] Taking advantage of the lower density of oil compared to soy sauce, this embodiment provides a soy sauce separation tank 100. This tank allows the oil and soy sauce to naturally separate under gravity, enabling rapid and convenient separation of the upper oil layer and the lower soy sauce layer, which are then collected separately into designated containers. This soy sauce separation tank 100 not only ensures effective separation of oil from the soy sauce and improves the production efficiency of high-quality soy sauce, but also allows for the unified collection of the separated oil, which can then be further processed or directly applied in the food, daily chemical, and other industrial sectors.

[0020] In the raw material pretreatment stage of soy sauce brewing, when processing oily raw materials (such as soybeans), a relatively gentle pressing method will produce light-pressed oil. This pressing method allows the oil in the raw materials to seep out without excessively damaging the cell structure. The amount of oil separated in this process is less than the amount of soy sauce, and it also reduces the amount of impurities (such as protein fragments and pigments in the raw materials) mixed into the oil and entering the soy sauce. Therefore, the soy sauce obtained by separating light-pressed oil is of higher quality and can meet the requirements for refined soy sauce flavor.

[0021] In soy sauce production, to increase the yield, the raw materials need to be subjected to high-intensity pressing, which produces heavy-pressed oil. The intense pressure completely destroys the cell structure of soybeans, causing a large amount of oil to be released from the cells. While heavy-pressing increases the yield, it also significantly increases the oil content. Furthermore, the severe damage to the soybean cell structure leads to the extraction of more impurities (such as protein fragments and pigments) along with the oil, which then enter the soy sauce. Therefore, heavy-pressed oil typically has a more complex composition than light-pressed oil, and the soy sauce obtained after separation usually requires further processing to meet specified quality requirements.

[0022] The soy sauce oil separation tank 100 provided in this embodiment includes a light-pressure oil tank 1, a heavy-pressure oil tank 2, an oil discharge chamber 3, a light-pressure oil discharge chamber 4, and a heavy-pressure oil discharge chamber 5. The light-pressure oil tank 1 and the heavy-pressure oil tank 2 are separated by a first partition 12. In actual soy sauce production, considering the relatively stable temperature of the underground environment and the avoidance of direct sunlight, and to reduce potential safety risks during soy sauce brewing, the soy sauce oil separation tank 100 is usually located underground to ensure that the soy sauce and oil can be separated in a relatively stable temperature environment. Furthermore, to facilitate the flow of light-pressure oil and heavy-pressure oil into the light-pressure oil tank 1 and heavy-pressure oil tank 2 respectively, in this embodiment, a light-pressure oil inlet 11 and a heavy-pressure oil inlet 21 are respectively provided above the light-pressure oil tank 1 and the heavy-pressure oil tank 2.

[0023] Because lightly pressed oil contains less oil, some soy sauce may mix with the oil during the oil separation process and be separated along with it. Therefore, in this embodiment, the oil layer in the lightly pressed oil tank 1 flows unidirectionally into the heavy-pressed oil tank 2 to achieve the initial separation of soy sauce and oil, and then separates again in the heavy-pressed oil tank to achieve the secondary separation of soy sauce and oil. (Reference) Figure 1 The top of the first partition 12 is lower than the other side walls of the light pressure oil tank 1. When the light pressure oil is injected into the light pressure oil tank 1 and naturally stratifies under gravity, as the light pressure oil continues to be injected, the height of the light pressure oil in the light pressure oil tank 1 will be higher than the top of the first partition 12. At this time, the upper layer of grease with lower density will overflow from the top of the first partition 12 and flow into the heavy pressure oil tank 2. To prevent the liquid in the heavy pressure oil tank 2 from flowing back into the light pressure oil tank 1, the side wall height of the heavy pressure oil tank 2 can be lower than the first partition 12.

[0024] In this embodiment, the grease discharge chamber 3 provided in the soy sauce separation tank 100 is used to collect or store the grease separated from the heavy-pressure oil tank 2, as shown in the reference. Figure 2 The grease discharge chamber 3 and the heavy-pressure oil tank 2 are separated by a second partition 22, the top of which is lower than the other side walls of the heavy-pressure oil tank 2. When the heavy-pressure oil is injected into the heavy-pressure oil tank 2 and naturally stratifies under gravity, as the heavy-pressure oil flowing out of the heavy-pressure oil inlet 21 and the grease overflowing from the light-pressure oil tank 1 are continuously injected into the heavy-pressure oil tank 2, until the liquid level in the heavy-pressure oil tank 2 is higher than the top of the second partition 22, the lower-density upper layer of grease will overflow from the top of the second partition 22 and flow into the grease discharge chamber 3. Because the heavy-pressure oil contains a large amount of grease, and with the continuous injection of grease overflowing from the light-pressure oil tank 1, the grease layer in the heavy-pressure oil tank 2 is relatively thick, and the stratification of soy sauce and grease is more pronounced. Therefore, when the grease layer in the heavy-pressure oil tank 2 begins to overflow from the top of the second partition 22, the grease entering the grease discharge chamber 3 has a higher purity.

[0025] In this embodiment, the light-pressure oil discharge chamber 4 in the soy sauce separation tank 100 is used to recover a portion of the soy sauce separated from the light-pressure oil tank 1. Since the light-pressure oil tank 1 only allows light-pressure oil to pass through, and the light-pressure oil contains less oil and other impurities, the soy sauce separated from the light-pressure oil tank 1 is of higher quality. This portion of soy sauce, after being passed into the light-pressure oil discharge chamber 4, can be used directly or after simple processing before being shipped out. (Reference) Figure 1 A first connecting pipe 13 is provided in the light-pressure oil discharge chamber 4. The first lower port 132 of the first connecting pipe 13 is connected to the bottom of the light-pressure oil tank 1, and the first upper port 131 of the first connecting pipe 13 extends to a position corresponding to and higher than the top of the first partition 12. Preferably, the height of the first upper port 131 is 5mm-10mm higher than the height of the top of the first partition 12. When the light-pressure oil introduced into the light-pressure oil tank 1 separates into layers under the action of gravity, the upper layer of liquid is the oil layer, and the lower layer of liquid is the soy sauce layer. As the light-pressure oil is continuously injected, when the upper liquid in the light-pressure oil tank 1, i.e., the oil layer, begins to overflow from the top of the first partition 12 into the heavy-pressure oil tank 2, the bottom position of the light-pressure oil tank 1, which is connected to the first lower port 132 of the first connecting pipe 13, is filled with the soy sauce layer. As the grease layer in the light-pressure oil tank 1 begins to overflow from the first partition 12 into the heavy-pressure oil tank 2, the upper surface of the grease layer is higher than the end face of the first upper port 131. According to the principle of communicating vessels, the soy sauce layer in the light-pressure oil tank 1 begins to flow from the first lower port 132 of the first connecting pipe 13 to the first upper port 131, and then from the first upper port 131 into the light-pressure oil discharge chamber 4, so as to complete the separation and collection of the soy sauce layer in the light-pressure oil.

[0026] In this embodiment, the heavy-pressed oil discharge chamber 5 in the soy sauce separation tank 100 is used to recover a portion of the soy sauce separated from the heavy-pressed oil tank 2. Because the heavy-pressed oil has a high oil content and contains a large amount of other impurities, the soy sauce collected in the heavy-pressed oil discharge chamber 5 is of poor quality. This portion of soy sauce still needs to be further processed in the next step before it can be used. (Reference) Figure 1 and Figure 2A second connecting pipe 23 is provided in the heavy-pressure oil discharge chamber 5. The second lower port 232 of the second connecting pipe 23 is connected to the bottom of the heavy-pressure oil tank 2, and the second upper port 231 of the second connecting pipe 23 extends to a position corresponding to and higher than the top of the second partition 22. Preferably, the height of the second upper port 231 is 5mm-10mm higher than the height of the top of the second partition 22. When the heavy-pressure oil introduced into the heavy-pressure oil tank 2 separates into layers under the action of gravity, the upper layer of liquid is an oil layer, and the lower layer is a soy sauce layer. As heavy-pressure oil and oil from the light-pressure oil tank 1 are continuously injected, the upper layer of liquid in the heavy-pressure oil tank 2, i.e., the oil layer, begins to overflow from the top of the second partition 22 into the oil discharge chamber 3. At this time, the bottom of the heavy-pressure oil tank 2, which is connected to the second lower port 232 of the second connecting pipe 23, is filled with the soy sauce layer. As the grease layer in the heavy-pressure oil tank 2 begins to overflow from the second partition 22 into the grease discharge chamber 3, the upper surface of the grease layer in the heavy-pressure oil tank 2 is higher than the end face of the second upper port 231. According to the principle of communicating vessels, the soy sauce layer in the heavy-pressure oil tank 2 begins to flow from the second lower port 232 of the second connecting pipe 23 to the second upper port 231, and then from the second upper port 231 into the heavy-pressure oil discharge chamber 5, so as to complete the separation and collection of the soy sauce layer in the heavy-pressure oil.

[0027] To ensure that the lower layer of soy sauce in the light-pressure oil tank 1 and the heavy-pressure oil tank 2, after stratification, can smoothly pass through the first connecting pipe 13 and the second connecting pipe 23, and enter the light-pressure oil discharge chamber 4 and the heavy-pressure oil discharge chamber 5 respectively for collection, in this embodiment, the first upper port 131 of the first connecting pipe 13 and the second upper port 231 of the second connecting pipe 23 are both height-adjustable threaded heads. Before the soy sauce separator 100 is put into use, the height of the threaded heads can be adjusted and fixed according to the specific height of the first partition 12 and the second partition 22. That is, the height of the first upper port 131 and the second upper port 231 is adjusted so that when the oil begins to overflow from the top of the first partition 12 and the second partition 22, the height of the upper surface of the oil layer in the light-pressure oil tank 1 and the heavy-pressure oil tank 2 can be higher than the height of the first upper port 131 and the second upper port 231 respectively. Thus, according to the principle of communicating vessels, the soy sauce layer can be smoothly discharged into the designated chamber.

[0028] In this embodiment, the bottom of the oil discharge chamber 3, the light-pressure oil discharge chamber 4, and the heavy-pressure oil discharge chamber 5 are all provided with discharge ports 6, which are used to discharge the oil and soy sauce of different qualities separated and collected in each chamber to other receiving containers (not shown in the figure) or to the next processing step (not shown in the figure). In order to discharge the oil and soy sauce from the discharge ports 6 more centrally and avoid spillage, in this embodiment, the inner walls of the oil discharge chamber 3, the light-pressure oil discharge chamber 4, and the heavy-pressure oil discharge chamber 5 are all shaped with a horizontal cross-sectional area that gradually decreases from top to bottom. This allows the oil or soy sauce entering each chamber to flow along the inner wall to the bottom of each chamber with a smaller horizontal cross-sectional area, and finally discharge from the discharge port 6 at the bottom of each chamber to the outside of the soy sauce separator 100, so that the separated soy sauce or oil can be collected or transferred to the next process.

[0029] Through the above methods, the soy sauce separation tank provided in this embodiment can quickly and conveniently separate the layered soy sauce and oil at low cost, thereby improving the production quality and efficiency of soy sauce.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
