Description

Technical Field

[0001] This invention relates to the field of enzyme hydrolysate separation equipment, and in particular to a multi-stage centrifuge device for enzyme hydrolysate separation. Background Technology

[0002] Enzymatic hydrolysis is a chemical reaction that uses enzymes as catalysts and has a wide range of applications. During the enzymatic hydrolysis of animal proteins, a large amount of oil is produced. This oil mixed in the hydrolysate can affect the quality of the final product. Existing technologies generally utilize the principle that oil and hydrolysate are immiscible and have different densities to separate the oil from the hydrolysate through static stratification. However, this separation method requires a long settling time, which is not conducive to improving separation efficiency. In addition, during separation, the close contact between the oil layer and the hydrolysate layer can lead to incomplete separation, thereby reducing the quality of the hydrolysate separation. In view of this, we propose a multi-stage centrifuge device for hydrolysate separation. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing enzyme hydrolysate separation equipment, namely, low separation quality and low separation efficiency, and to propose a multi-stage centrifuge device for enzyme hydrolysate separation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The separation chamber is provided with a feed block for filtering insoluble matter, and a multi-stage centrifuge mechanism for separating oil components in the enzymatic hydrolysate is provided in the separation chamber and below the feed block.

[0006] The multi-stage centrifugal mechanism includes a primary separation cylinder fixedly installed in a separation chamber and a secondary separation cylinder connected to a discharge pipe. The primary and secondary separation cylinders each have a primary purification annular cavity and a secondary purification annular cavity connected to the discharge pipe, respectively. The primary and secondary purification annular cavities each have purification holes connected to the primary or secondary separation cylinder. The lower part of the primary separation cylinder has a guide pipe that communicates with both the secondary separation cylinder and the primary purification annular cavity. Both the primary and secondary separation cylinders contain centrifugal components for driving the enzymatic hydrolysate centrifugation and impurity removal components for removing grease. The separation chamber contains a drive component and a transmission component for driving the centrifugal components. One-way valves are provided at the discharge hole, both ends of the guide pipe, and within the impurity removal annular cavity.

[0007] Preferably, the centrifugal assembly includes a rotating tube rotatably mounted in a primary separation cylinder and a rotating rod rotatably mounted in a secondary separation cylinder, and centrifugal plates are provided on the outside of both the rotating tube and the rotating rod.

[0008] Preferably, the impurity removal assembly includes impurity removal annular cavities respectively opened in the primary separation cylinder and the secondary separation cylinder, and the separation box is equipped with an impurity removal pipe communicating with the impurity removal annular cavities.

[0009] Preferably, the upper end of the rotating tube is connected to the feed inlet via a feeding block, and it is provided with a discharge outlet that connects to the inner cavity of the primary separation cylinder. The discharge hole or the outlet of the guide pipe is respectively located in the middle of the primary separation cylinder and the secondary separation cylinder.

[0010] Preferably, the one-way valve includes conical cavities respectively opened in the discharge port, both ends of the guide pipe and the impurity removal ring cavity, and a one-way baffle is elastically installed in the conical cavity.

[0011] Preferably, the drive assembly includes a drive motor installed on one side of the separation box, a drive wheel one coaxially mounted on the output end of the drive motor, a drive wheel two rotatably mounted on the bottom of the first-stage separation cylinder and fixed coaxially with the rotating tube, and a drive belt externally driven by the drive wheel one and the drive wheel two.

[0012] Preferably, the transmission assembly includes a transmission gear ring coaxially mounted below the second drive wheel, a first transmission gear meshing with the inner side of the transmission gear ring and rotatably connected to the second-stage separator cylinder, and a second transmission gear meshing with the first transmission gear on one side and fixed coaxially with the rotating rod.

[0013] Preferably, the feeding block includes a feeding cavity inside the feeding block, the lower part of the feeding block is provided with an output pipe that communicates with the feeding cavity, and the output pipe is interconnected with the inner cavity of the rotating tube, the upper part of the feeding block is equipped with an insoluble filter screen, and a cleaning baffle is installed on one side of the separation box near the insoluble filter screen.

[0014] Preferably, the rotating tube is coaxially sleeved outside the output tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention utilizes the centrifugal force generated when the enzymatic hydrolysate is rotated by the rotating tube, rotating rod, and centrifuge plate. This forces the oils in the enzymatic hydrolysate to quickly accumulate in the lower part of the hydrolysate. With the cooperation of the impurity removal ring chamber, the purpose of separating the oils is achieved. Compared with the traditional separation mode, this method greatly reduces the required separation time, thereby improving the separation efficiency of the device. In addition, under the action of the primary purification ring chamber, purification hole, and feed pipe, the enzymatic hydrolysate in the primary separation cylinder can be transferred to the secondary separation cylinder for secondary separation, thereby improving the separation effect of the enzymatic hydrolysate and facilitating the promotion of the equipment.

[0017] 2. This invention achieves secondary separation of the enzymatic hydrolysate through the cooperation of the transmission assembly, rotating rod, and centrifuge plate. Furthermore, the rotational speed of the rotating rod is increased by the meshing of the transmission gear ring, transmission gear one, and transmission gear two, thereby increasing the centrifugal force of the enzymatic hydrolysate during rotation in the secondary separation cylinder and further improving the separation quality of the enzymatic hydrolysate and oil.

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

[0026] Example 1

[0027] Reference Figures 1-6 A multi-stage centrifuge device for separating enzymatic hydrolysate includes a separation chamber 1, and an inlet and an outlet pipe respectively installed at the top or bottom of the separation chamber 1. The separation chamber 1 is equipped with a feed block 3 for filtering insoluble matter. The separation chamber 1 is equipped with a multi-stage centrifuge mechanism 2 for separating oil components in the enzymatic hydrolysate, located below the feed block 3. During separation, the enzymatic hydrolysate is first fed into the separation chamber 1 through the feed inlet. Under the processing of the feed block 3, the insoluble solids in the enzymatic hydrolysate can be filtered out, thereby reducing the difficulty of cleaning impurities in the enzymatic hydrolysate. Then, the multi-stage centrifuge mechanism 2 is controlled to operate, and the oil is separated from the enzymatic hydrolysate by utilizing the physical characteristics that oil is insoluble in water and has a density less than that of water, thereby completing the separation of the enzymatic hydrolysate.

[0028] The multi-stage centrifuge mechanism 2 includes a primary separation cylinder 21 fixedly installed in the separation chamber 1 and a secondary separation cylinder 22 connected to the discharge pipe. The primary separation cylinder 21 and the secondary separation cylinder 22 each have a primary purification annular cavity 29 and a secondary purification annular cavity 210 connected to the discharge pipe, respectively. The primary purification annular cavity 29 and the secondary purification annular cavity 210 each have purification holes 211 connected to the primary separation cylinder 21 or the secondary separation cylinder 22, respectively. The lower part of the primary separation cylinder 21 has a guide pipe 24 that is interconnected with both the secondary separation cylinder 22 and the primary purification annular cavity 29. Both the primary separation cylinder 21 and the secondary separation cylinder 22 are equipped with features for driving the enzymatic hydrolysate to centrifuge. The centrifugal assembly 23 for centrifugal motion and the impurity removal assembly 28 for removing grease are located in the separation chamber 1. A drive assembly 26 and a transmission assembly 27 are provided to drive the centrifugal assembly 23. One-way valves 25 are installed at the discharge port, both ends of the feed pipe 24, and in the impurity removal ring cavity 281. When the enzymatic hydrolysate passes over the feed block 3 and enters the primary separation cylinder 21, the drive assembly 26 can be activated to drive the centrifugal assembly 23. This rotation of the enzymatic hydrolysate in the primary separation cylinder 21 generates centrifugal motion. Because grease is insoluble in water and has a lower density than water, it will be centrifuged during the centrifugal rotation of the enzymatic hydrolysate. Under the influence of force, the oil gradually accumulates in the lower part of the enzymatic hydrolysate, achieving rapid separation of the oil and the enzymatic hydrolysate. Compared with the traditional separation mode, this greatly reduces the required separation time, thereby improving the separation efficiency of the device. Simultaneously, under the operation of the centrifugal assembly 23, the outer ring of enzymatic hydrolysate separated from the oil rises until it contacts the purification orifice 211. It then enters the primary purification annular cavity 29 along the purification orifice 211. Since the inner cavity of the primary purification annular cavity 29 is connected to the feed pipe 24, the enzymatic hydrolysate entering the primary purification annular cavity 29 quickly enters the feed pipe 24 and then flows along the feed pipe 24 into the secondary separation cylinder 22. At this time, the centrifugal component 23 installed in the secondary separation cylinder 22 will drive the enzymatic hydrolysate entering the secondary separation cylinder 22 to repeatedly centrifuge, thereby performing secondary separation of the enzymatic hydrolysate. The separated enzymatic hydrolysate enters the secondary purification ring 210 through the purification hole 211 set on the secondary purification ring 210, and is finally separated through the feed pipe, thus completing the separation task. The two-stage separation operation improves the separation quality of the enzymatic hydrolysate, which is conducive to the promotion of the equipment. In addition, the grease accumulated in the lower part of the primary separation cylinder 21 and the secondary separation cylinder 22 will be discharged through the impurity removal component 28 during the separation process, thereby completing the separation of grease.

[0029] The centrifuge assembly 23 includes a rotating tube 231 rotatably mounted in the primary separation cylinder 21 and a rotating rod 233 rotatably mounted in the secondary separation cylinder 22. Both the rotating tube 231 and the rotating rod 233 are equipped with centrifuge plates 232. During centrifugation, the rotating tube 231 can be driven to rotate by the drive assembly 26. Since the rotating tube 231 is equipped with centrifuge plates 232, the rotating tube 231 can drive the enzymatic hydrolysate in the primary separation cylinder 21 to centrifuge through the centrifuge plates 232. Since the rotating rod 233 is rotatably mounted in the secondary centrifuge cylinder, when the rotating rod 233 rotates under the action of the drive assembly 26 and the transmission assembly 27, it will drive the enzymatic hydrolysate that has entered the secondary separation cylinder 22 to undergo repeated centrifugation through the centrifuge plates 232 mounted on its exterior, thereby performing secondary separation of the enzymatic hydrolysate.

[0030] The impurity removal assembly 28 includes impurity removal ring cavities 281 respectively opened in the primary separation cylinder 21 and the secondary separation cylinder 22. The separation box 1 is equipped with an impurity removal pipe 282 that communicates with the impurity removal ring cavity 281. During the separation process, the grease that accumulates in the lower part of the primary separation cylinder 21 and the secondary separation cylinder 22 will slowly pass through the one-way valve 25 and enter the impurity removal ring cavity 281 as the mass increases, and finally be discharged from the impurity removal pipe 282, thereby completing the grease separation operation.

[0031] The upper end of the rotating tube 231 is connected to the feed inlet through the feeding block 3, and it is provided with a discharge port that connects to the inner cavity of the primary separation cylinder 21. The discharge hole or the outlet of the guide pipe 24 is respectively located in the middle of the primary separation cylinder 21 and the secondary separation cylinder 22. The special setting of the discharge hole and the outlet of the guide pipe 24 can prevent the enzymatic hydrolysate that has just entered the primary separation cylinder 21 or the secondary separation cylinder 22 from being discharged from the impurity removal ring cavity 281, the primary purification ring cavity 29 and the secondary purification ring cavity 210, which further improves the quality of enzymatic hydrolysate separation and improves the practicality of the device.

[0032] The one-way valve 25 includes a conical cavity 251 respectively opened in the discharge port, both ends of the feed pipe 24 and the impurity removal ring cavity 281. A one-way baffle 252 is elastically installed in the conical cavity 251. When the mass of the enzymatic hydrolysate on one side of the conical cavity 251 reaches the set value, it will squeeze the one-way baffle 252 to move, thereby opening the one-way valve 25 and completing the flow of enzymatic hydrolysate and oil in the separation box 1. In addition, as shown in the figure, a solenoid valve is provided on the impurity removal ring cavity 281, which is intermittently arranged with the one-way valve 25. After the enzymatic hydrolysate separation is completed, the solenoid valve can be opened to discharge the remaining liquid in the separation box 1 through the impurity removal ring cavity 281 from the impurity removal pipe 282.

[0033] The drive assembly 26 includes a drive motor 261 mounted on one side of the separation chamber 1. A drive wheel 262 is coaxially mounted on the output end of the drive motor 261. A drive wheel 264, coaxially fixed with the rotating tube 231, is rotatably mounted on the bottom of the primary separation cylinder 21. A drive belt 263 is externally sleeved on the drive wheel 262 and the drive wheel 264. During separation, the drive motor 261 is started to drive the drive wheel 262 to rotate, and the drive wheel 264 is driven to rotate through the drive belt 263 externally sleeved on it. Since the drive wheel 264 is coaxially fixed with the rotating tube 231, the rotation of the drive wheel 264 will drive the rotating tube 231 to rotate, thereby driving the centrifugal motion of the enzymatic hydrolysate in the primary separation cylinder 21.

[0034] The transmission assembly 27 includes a transmission gear ring 271 coaxially mounted below the second drive wheel 264. A first transmission gear 272, rotatably connected to the secondary separation cylinder 22, meshes inside the transmission gear ring 271. A second transmission gear 273, coaxially fixed to the rotating rod 233, meshes on one side of the first transmission gear 272. Since the transmission gear ring 271 is coaxially mounted below the second drive wheel 264, it synchronously drives the transmission gear ring 271 to rotate when the second drive wheel 264 rotates. Because the transmission gear ring 271 and the first transmission gear 272 mesh with each other, the transmission gear ring 271 rotates... The transmission gear 272 drives the transmission gear 273 to rotate, which in turn drives the rotating rod 233, which is fixed coaxially with the transmission gear 273, to rotate. This achieves centrifugal motion of the enzymatic hydrolysate in the secondary separation cylinder 22. In addition, since the number of teeth on the transmission gear ring 271 and the transmission gear 272 is greater than that on the transmission gear 273, the rotational speed of the rotating rod 233 will be increased synchronously when the transmission assembly 27 drives the rotating rod 233 to rotate. This increases the centrifugal force of the enzymatic hydrolysate when it rotates in the secondary separation cylinder 22, further improving the separation effect of the enzymatic hydrolysate and the oil.

[0035] Example 2

[0036] Reference Figures 1-6This embodiment is basically the same as Embodiment 1, but with an optimization: the feeding block 3 includes a feeding cavity 31 inside the feeding block 3. The lower part of the feeding block 3 is provided with an output pipe 34 communicating with the feeding cavity 31, and the output pipe 34 is interconnected with the inner cavity of the rotating pipe 231. An insoluble matter filter screen 32 is installed on the upper part of the feeding block 3. A cleaning baffle 33 is installed on one side of the separation box 1 near the insoluble matter filter screen 32. After the enzymatic hydrolysate enters the separation box 1 through the inlet and comes into contact with the feeding block 3, it will pass over the insoluble matter filter screen 32 and enter the feeding cavity 31, where the encapsulated insoluble solids will be... As shown in Figures 1 and 2, the feeding chamber 31 is shaped like a "√", and the output pipe 34 is installed at the lowest point of the feeding chamber 31. Therefore, the enzymatic hydrolysate can quickly enter the output pipe 34 from the feeding chamber 31, which improves the separation efficiency of the enzymatic hydrolysate to a certain extent. Since the two sides of the feeding chamber 31 are higher on one side and lower on the other, the insoluble matter filter screen 32 installed on the feeding block 3 is tilted, which makes it easier for the insoluble solids filtered out on the insoluble matter filter screen 32 to slide down to the cleaning baffle 33. After a certain number of batches are separated, the cleaning baffle 33 can be opened to clean the insoluble solids.

[0037] The rotating tube 231 is coaxially sleeved outside the output tube 34, as shown in the figure. One end of the output tube 34 is located inside the rotating tube 231 and does not contact the inner wall of the rotating tube 231, which is beneficial to the conduction and separation of the enzyme hydrolysate.
