Soybean oil separation system used in soy sauce production process

Abstract

This utility model discloses a soybean oil separation system for soy sauce production. The system includes a first storage unit, a separation device, and a flow control device. The first storage unit stores mixed oil. The separation device has two output ends and is used to separate the mixed oil into soybean oil and soy sauce, which are then transported separately through the two output ends. The flow control device is located between the separation device and the first storage unit, and is connected to a first flow path and a second flow path. The second flow path is connected to the separation device. Because the flow rates of soybean oil and soy sauce are different, when the soybean oil layer is extracted, the flow control device can detect the flow rate change and promptly redirect the flow of soybean oil to the first flow path, preventing soybean oil from entering the separation device. This reduces the risk of soybean oil mixing with soy sauce, improves the quality of soy sauce production, and avoids production losses.

Description

Technical Field

[0001] This utility model relates to the field of soy sauce manufacturing technology, and in particular to a soybean oil separation system used in soy sauce production processes. Background Technology

[0002] In traditional soy sauce manufacturing, the blended oil after pressing soybeans contains both soy sauce and soybean oil. This blend is temporarily stored in a tank where it naturally separates into layers. Since soybean oil is less dense than soy sauce, it floats to the top, forming a soybean oil layer, while the soy sauce sinks to the bottom, forming a soy sauce layer. The separated soy sauce layer in the storage tank needs to be extracted and centrifuged for further soybean oil separation. Currently, the extraction of soy sauce from the storage tank is done manually, which is prone to errors or delays. If the extraction is not stopped promptly when the soybean oil layer is reached, the soybean oil will mix with the soy sauce, resulting in incomplete separation, affecting the quality of the soy sauce and increasing production costs.

[0023] In traditional soy sauce manufacturing, the blended oil after pressing soybeans contains both soy sauce and soybean oil. This blend is temporarily stored in a tank where it naturally separates into layers. Since soybean oil is less dense than soy sauce, it floats to the top, forming a soybean oil layer, while the soy sauce sinks to the bottom, forming a soy sauce layer. The separated soy sauce layer in the storage tank needs to be extracted and centrifuged for further soybean oil separation. Currently, the extraction of soy sauce from the storage tank is done manually, which is prone to errors or delays. If the extraction is not stopped promptly when the soybean oil layer is reached, the soybean oil will mix with the soy sauce, resulting in incomplete separation, affecting the quality of the soy sauce and increasing production costs.

[0024] Therefore, as shown in the figure, the soybean oil separation system for soy sauce production proposed in this utility model includes: a first storage unit 100, a separation device 200, a flow control device 300, a second storage unit 400, a third storage unit 500, a first flow path 600, and a second flow path 700. The first storage unit 100 stores a mixed oil containing soybean oil and soy sauce. In actual production, the mixed oil will naturally separate into layers in the first storage unit 100. Due to the lower density of soybean oil, it will float on the upper layer to form a soybean oil layer, while the soy sauce will sink to the lower layer to form a soy sauce layer. The flow control device 300 is disposed between the separation device 200 and the first storage unit 100. The flow control device 300 is connected to the first flow path 600 and the second flow path 700. The second flow path 700 is connected to the separation device 200. The flow control device 300 can detect the flow rate of the mixed oil and control the flow of the mixed oil to the first flow path 600 or the second flow path 700. In some applications, because soybean oil and soy sauce have different flow rates, when the soybean oil layer is extracted, the flow measurement and control device 300 can detect the flow change and promptly switch the flow direction of the soybean oil to the first flow path 600 to prevent the soybean oil from entering the separation device 200. This reduces the risk of soybean oil mixing with soy sauce, improves the quality of soy sauce production, and avoids production losses.

[0025] In some embodiments of this utility model, as shown in the figures, the flow measurement and control device 300 includes a flow meter 310, a data logger, and a control component 320. The flow meter 310 detects the flow rate of the mixed oil in real time and generates a flow rate signal. The data logger receives and records the flow rate signal. When the flow rate signal changes by a preset amplitude, the data logger generates a trigger signal and sends it to the control component 320. The control component 320 controls the flow direction of the mixed oil according to the received signal. It should be noted that the data logger and the control component 320 are electrically connected to a control system. When the flow rate of the flow meter 310 changes, the data logger sends a signal to the control system. The control system alarms and simultaneously sends an electrical signal to the control component 320 to control the flow direction of the mixed oil, thereby switching the flow direction of soybean oil in a timely manner to prevent it from mixing into the soy sauce and affecting the production quality.

[0026] Specifically, in some embodiments of this utility model, the data logger is preferably a paperless recorder for receiving and recording flow rate signals. The paperless recorder integrates a signal receiving module, a data storage module, a threshold comparison module, and a signal output module. Its signal receiving module receives the flow rate signal transmitted by the flow meter 310 in real time, and the data storage module continuously records the flow rate value and time information corresponding to the flow rate signal, forming a traceable flow data curve. Simultaneously, the threshold comparison module has a built-in preset flow rate change threshold, which can be manually set according to the requirements of the mixed oil conveying process.

[0027] In some embodiments of this utility model, as shown in the figures, the control component 320 includes a first control valve 321 and a second control valve 322, both preferably electromagnetic pneumatic valves, which offer fast response and high control precision. The first control valve 321 is located in the first flow path 600, and the second control valve 322 is located in the second flow path 700. Under normal operating conditions, the mixed oil is transported to the separation device 200 via the second flow path 700. When the flow meter 310 detects a significant increase in flow rate, indicating that the soybean oil layer has begun to be extracted, the control component 320 closes the second control valve 322 and opens the first control valve 321, switching the mixed oil to the first flow path 600. It should be noted that when the flow rate changes at the flow meter 310, the paperless recorder sends a signal to the control system, which alarms and simultaneously sends an electrical signal to the control component 320, thereby closing the second control valve 322 and opening the first control valve 321, allowing the soybean oil to flow from the first conduction path to the second storage unit 400.

[0028] In some embodiments of this utility model, as shown in the figure, the first flow path 600 is connected to the second storage unit 400. Soybean oil separated by the separation device 200 can flow to the second storage unit 400 for storage. Soybean oil separated by the first storage unit 100 can also flow through the first flow path 600 to the second storage unit 400 for storage. The second storage unit 400 can serve as a unified storage terminal for soybean oil, avoiding the separation device 200 and the first storage unit 100 from being stored in different containers, thus reducing space waste caused by decentralized storage.

[0029] In some embodiments of this utility model, as shown in the figure, a centrifugal pump 110 is provided between the first storage unit 100 and the flow measurement and control device 300. The centrifugal pump 110 is used to pump and pressurize the mixed oil. After the mixed oil settles and separates in the first storage unit 100, the centrifugal pump 110 starts, drawing out the lower layer of soy sauce. After flowing through the flow measurement and control device 300, it enters the separation device 200 through the second flow path 700 for centrifugal separation. The separated soybean oil and soy sauce enter the second storage unit 400 and the third storage unit 500, respectively. When the flow meter 310 detects a sudden increase in flow rate, indicating that the soybean oil layer has been reached, the data logger sends a signal, and the control component 320 activates, switching the oil path to the first flow path 600. The soybean oil directly enters the second storage unit 400, preventing the soybean oil from entering the separation device 200, thereby reducing the risk of soybean oil mixing with soy sauce, improving the quality of soy sauce production, and avoiding production losses.

[0030] In some embodiments of this utility model, as shown in the figure, a pressure sensor is provided at the output end of the first storage unit 100. The start and stop of the centrifugal pump 110 can be controlled by the pressure sensor at the output end of the first storage unit 100. When the mixed oil in the first storage unit 100 is evacuated, the pressure sensor detects the pressure change and sends a signal to stop the centrifugal pump 110 from working. The flow measurement and control device 300 controls the first control valve 321 to close, thereby closing the first flow path 600, that is, stopping the delivery of soybean oil, thus avoiding idling or equipment damage.

[0031] In some embodiments of this utility model, as shown in the figure, the separation device 200 is preferably a centrifugal separator with two output ends, which are used to output the separated soybean oil and soy sauce respectively. The soybean oil output end is connected to the second storage unit 400, and the soy sauce output end is connected to the third storage unit 500. The first flow path 600 is connected to the second storage unit 400, so that the separated soybean oil can directly enter the second storage unit 400 for storage without passing through the separation device 200, thereby preventing soybean oil from mixing with the soy sauce.

[0032] In some embodiments of this utility model, as shown in the figures, the soybean oil separation system of this utility model effectively avoids the untimely and error-prone nature of manual operation through automated detection and control, significantly improving the production quality of soy sauce and the recovery rate of soybean oil, while reducing production costs and equipment wear and tear. The system has a reasonable structure, rapid response, and high reliability, making it suitable for the large-scale, continuous production needs of soy sauce production enterprises. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of this utility model.
