Description

Technical Field

[0001] This utility model belongs to the field of enzymatic extraction technology, and in particular relates to an enzymatic extraction device. Background Technology

[0002] Enzymatic extraction is a biotechnology that uses enzymes to break down and extract active substances from products such as meat. Specifically, meat products, such as seafood like fish, contain a large amount of protein, which is composed of various amino acids. Therefore, enzymatic extraction technology breaks down proteins into amino acids, resulting not only in enzymatically hydrolyzed products with unique flavors, but also in amino acid products with higher nutritional value.

[0003] Therefore, enzymatic extraction of meat products has a wide range of industrial applications. For example, in the production of seasonings, flavor amino acid products are extracted through enzymatic extraction technology and used as seasonings in food cooking.

[0004] During the enzymatic extraction process, the meat products are placed in a cage-shaped extraction cage for solid-liquid separation. Specifically, as the enzymatic hydrolysis progresses, the material (meat products such as fish) gradually breaks down under the action of enzymes. Therefore, the extraction cage facilitates the separation of the extraction residue (the decomposition products such as flavor amino acids from enzymatic hydrolysis are dissolved in the extraction solvent, waiting for subsequent desolventization to obtain the flavor amino acid products).

[0005] However, during enzymatic hydrolysis, due to the inability of biological enzymes to tolerate high temperatures, enzymatic hydrolysis is carried out within the range of the enzyme's active temperature (e.g., 37 degrees Celsius). Excessive temperature can easily deactivate the enzyme. Consequently, during enzymatic extraction, the dynamic movement of the solvent (the higher the temperature, the more vigorous the movement of solvent molecules – Brownian motion) is weaker, and a large amount of meat product accumulates in the cage structure, resulting in a slow enzymatic extraction process.

[0006] Therefore, in actual operation, the contact between solvent molecules (the enzyme is also dissolved in the solvent) and meat products is increased by driving the extraction cage to rotate, so as to improve the efficiency of enzymatic extraction.

[0007] However, because the cylindrical extraction cage has a slow effect on the flow of the solvent during the enzymatic extraction process, especially during slow stirring, the solvent and the biological enzymes dissolved in the solvent cannot be fully dispersed and move during the enzymatic extraction process, and cannot fully interact with the meat in the cage.

[0008] Meanwhile, during the enzymatic extraction process, meat decomposes, but due to the slow dispersion of the solvent, the local concentration of decomposition products is too high. Since biodecomposition is essentially a chemical process, excessive product concentration inhibits the chemical reaction process and further affects the enzymatic hydrolysis efficiency. Utility Model Content

[0009] Based on the above background, the purpose of this utility model is to provide an enzymatic extraction device.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] An enzymatic extraction device includes an extraction cylinder, wherein a lifting cage mechanism is rotatably connected inside the extraction cylinder;

[0012] The cage lifting mechanism includes a cage body, on which several agitation units are hingedly installed. Each agitation unit includes an upper agitation rod and a lower agitation rod respectively hingedly installed at the upper and lower ends of the cage body.

[0013] The upper and lower stirring rods are each hinged with several auxiliary stirring rod structures that swing in opposite directions.

[0014] Preferably, the extraction cylinder is connected to an inlet pipe structure and an outlet pipe structure that are spaced apart vertically.

[0015] The top of the extraction cylinder is detachably fitted with an upper cover;

[0016] The top of the cage is rotatably connected to the top cover.

[0017] Preferably, the cage includes a lower base, and a stainless steel cage cylinder with a plurality of mesh holes is welded and fixedly connected to the top of the lower base.

[0018] The top of the stainless steel cage is fixedly connected to a mouth ring bracket.

[0019] The upper and lower stirring rods are respectively hinged to the mouth ring bracket and the lower base.

[0020] Preferably, the top of the upper stirring rod and the bottom of the lower stirring rod are respectively fixedly connected with hinge seats;

[0021] The mouth ring bracket and the lower base are respectively provided with hinge slots on their side walls, and the hinge seat is hinged to the hinge slot by a pin.

[0022] Preferably, the upper and lower stirring rods are each provided with a long hinge slot;

[0023] The auxiliary stirring rod structure includes a short stirring rod, the inner end of which is fixedly connected to a hinge seat body, which is hingedly installed in a long hinge slot.

[0024] The hinge body is hinged to the long hinge slot by a pin.

[0025] Preferably, a limiting rotating head is fixedly connected to the bottom center of the lower base;

[0026] A turntable is rotatably connected to the bottom center of the extraction cylinder, and a slot is provided on the top of the turntable to cooperate with the limiting turn head.

[0027] A motor is fixedly installed at the bottom center of the extraction cylinder, and the output shaft of the motor is fixedly installed at the bottom of the turntable.

[0028] Preferably, the limiting rotating head is in the shape of a regular hexagon, and the slot is a regular hexagonal groove.

[0029] Preferably, a cage top cover is detachably installed on the top of the mouth ring bracket;

[0030] A rotating shaft is fixedly connected to the top center of the cage cover, and an installation opening is provided at the top center of the top cover, in which a bearing is fixedly installed.

[0031] The rotating shaft is installed on the inner ring of the bearing via a limiting plug-in structure.

[0032] Preferably, a tension spring is fixedly connected between the free ends of the upper and lower stirring rods.

[0033] This utility model has the following beneficial effects:

[0034] 1. During extraction, the rotating cage mechanism drives the upper and lower stirring rods to rotate. In their hinged position, the upper and lower stirring rods are flung outwards. Therefore, during extraction, the amplitude of the flung rods' dispersion is controlled based on the extraction progress (cage rotation speed), thus controlling the agitation amplitude of the solvent system. For example, to accelerate the extraction process, the rotation speed of the cage mechanism is increased. With this increased rotation speed, the amplitude of the flung rods' dispersion increases under centrifugal force.

[0035] 2. The structure consists of several auxiliary stirring rods that are hinged to the upper and lower stirring rods and swing in opposite directions.

[0036] Specifically, both the upper and lower stirring rods are provided with long hinge slots; the auxiliary stirring rod structure includes a short stirring rod, the inner end of which is fixedly connected to a hinge seat, which is hingedly installed in the long hinge slot; the hinge seat is hinged in the long hinge slot via a pin. Specifically, the short stirring rods disperse inwards and outwards. When the cage rotates, the short stirring rods disperse in the following order from top to bottom: outwards-inwards-outwards-inwards… Therefore, the short stirring rods are hinged in an alternating inwards and outwards manner. This structure further enables the extraction solvent to be thoroughly stirred and dispersed in different directions by multiple short stirring rods. Attached Figure Description

[0049] Example 1

[0050] like Figure 1-7 As shown, an enzymatic extraction device includes an extraction cylinder 1, which is a stainless steel extraction cylinder disclosed in the prior art, with the same structure as existing extraction cylinders 1. The extraction cylinder 1 is connected to an inlet pipe structure 12 and an outlet pipe structure 13, which are arranged at intervals (each equipped with a valve for pumping in the extractant and enzyme, while the extract is pumped out from the outlet pipe structure 13). A top cover 11 is detachably installed on the top of the extraction cylinder 1. Specifically, an annular flange is welded to the edge of the opening of the extraction cylinder 1, and several screws are welded onto the annular flange, passing through the top cover 11. Nuts are threaded onto the screws.

[0051] During operation, the top cover 11 can be opened using the methods described above.

[0052] Meanwhile, a lifting cage mechanism 2 is rotatably connected inside the extraction cylinder 1. The lifting cage mechanism 2 is a cage-shaped structure. The enzyme-extracted meat (such as fish meat) is placed in the lifting cage mechanism 2 and immersed in the extraction solvent and enzyme agent by pumping.

[0053] Specifically, the cage lifting mechanism 2 includes a cage body, on which several stirring units 23 are hinged. Each stirring unit 23 includes an upper stirring rod 231 and a lower stirring rod 232, which are respectively hinged to the upper and lower ends of the cage body.

[0054] Specifically, the cage body includes a lower base 24, and a stainless steel cage cylinder 21 (2.5mm thick) with several mesh holes is welded and fixedly connected to the top of the lower base 24. The size of the cage cylinder is adapted to the size of the extraction cylinder 1.

[0055] The top of the stainless steel cage 21 is welded and fixedly connected to a mouth ring bracket; the upper stirring rod 231 and the lower stirring rod 232 are respectively hinged to the mouth ring bracket and the lower base 24.

[0056] The upper stirring rod 231 and the lower stirring rod 232 are 60cm long. Under normal circumstances, the upper stirring rod 231 and the lower stirring rod 232 are in a hanging position when in the hinged state. During extraction, the upper stirring rod 231 and the lower stirring rod 232 rotate under the drive of the rotating cage mechanism 2, while the upper stirring rod 231 and the lower stirring rod 232 in the hinged state are flung outward. Therefore, during the extraction process, the amplitude of the flung rod 231 and the lower stirring rod 232 is controlled according to the extraction progress (rotation speed of the cage), thereby controlling the stirring amplitude of the solvent system.

[0057] During the extraction process, in order to speed up the extraction process, the rotation speed of the lifting cage mechanism 2 is increased. After the rotation speed of the lifting cage mechanism 2 is increased, the amplitude of the upper stirring rod 231 and the lower stirring rod 232 being flung apart increases under the action of centrifugal force.

[0058] The hinge structure of the upper stirring rod 231 and the lower stirring rod 232 is as follows: the top of the upper stirring rod 231 and the bottom of the lower stirring rod 232 are respectively fixedly connected to the hinge seat A; correspondingly, the side wall of the mouth ring bracket and the lower base 24 are respectively provided with hinge slots, and the hinge seat A is hinged on the hinge slot by a pin.

[0059] The above structure enables the upper and lower stirring rods 231 and 232 to disperse the material according to the rotation speed of the cage during the cage rotation process, thereby improving the extraction effect.

[0060] The aforementioned rotating structure of the cage is a conventional method disclosed in the prior art. Specifically, it is the same as the existing drive cage rotating structure, with a limit rotating head B (shaped like a regular hexagon) fixedly connected to the bottom center of the lower base 24.

[0061] Meanwhile, a turntable C is rotatably connected to the bottom center of the extraction cylinder 1. The top of the turntable C has a slot that cooperates with the limiting turn head. The slot is a regular hexagonal groove.

[0062] Meanwhile, according to the existing method of driving the cage to rotate, a motor (not shown in the figure) is fixedly installed at the bottom center of the extraction cylinder 1, and the output shaft of the motor is fixedly installed at the bottom of the turntable C. According to the existing method, the output shaft of the motor is fixedly installed at the bottom of the turntable C, and the motor sleeve for mounting the motor is also fixedly installed at the bottom of the extraction cylinder 1.

[0063] Meanwhile, in accordance with the existing method, several support frames (not shown in the figure) are welded to the bottom of the extraction cylinder 1 to suspend it in the air and support the extraction cylinder 1.

[0064] Meanwhile, in order to achieve sealed rotation, a sealed bearing is installed at the bottom of the extraction cylinder 1, which is the same as the existing sealing structure, and the motor output shaft is connected to the sealed bearing for rotation.

[0065] Meanwhile, similar to the existing cage structure rotation structure, the top of the above-mentioned mouth ring bracket is detachably fitted with a cage top cover 22 (the method is: several circumferentially distributed mounting screws are welded to the top of the mouth ring bracket, and the mounting screws pass through the cage top cover 22 and are tightened with locking nuts).

[0066] Meanwhile, a rotating shaft 221 is fixedly connected to the top center of the cage top cover 22, and an installation port is opened at the top center of the upper top cover 11, in which a bearing 111 is fixedly installed; the rotating shaft 221 is installed on the inner ring of the bearing 111 through a limiting insertion structure. Specifically, the insertion structure includes several protrusions integrally formed on the outer wall of the rotating shaft 221, and correspondingly, the inner ring of the bearing 111 has a matching groove.

[0067] When the cage is hoisted to the limit position and the rotating head is inserted into the slot, the top cover 11 is installed in the manner described above. At the same time, the protrusion on the rotating shaft is inserted into the bearing slot (i.e., the rotating shaft inserts into the bearing). After the top cover 11 is fixedly installed, the rotating shaft is rotatably connected to the bearing.

[0068] Driven by a motor, the cage can rotate smoothly.

[0069] The rotating cage, according to the above principle, achieves thorough agitation of the extraction solvent through centrifugal dispersion by the upper stirring rod 231 and the lower stirring rod 232.

[0070] Example 2

[0071] like Figure 1-7 As shown, in order to further improve the solvent stirring effect, based on the structure of Example 1, several auxiliary stirring rod structures that swing in opposite directions are respectively hinged to the upper stirring rod 231 and the lower stirring rod 232.

[0072] Specifically, the upper stirring rod 231 and the lower stirring rod 232 are respectively provided with long hinge slots; the auxiliary stirring rod structure includes a short stirring rod 231, the inner end of which is fixedly connected to a hinge seat body, which is hingedly installed in the long hinge slot; the hinge seat body is hingedly installed in the long hinge slot through a pin.

[0073] Specifically, the short stirring rod 231 is thrown outwards and inwards. Specifically, when the cage rotates, the short stirring rod 231 is thrown outwards in the following order from top to bottom: outwards-inwards-outwards-inwards… Therefore, the short stirring rod 231 is hinged in an alternating inwards and outwards hinged installation.

[0074] The above structure enables the extraction solvent to be further stirred and dispersed in different directions by multiple short stirring rods 231.

[0075] Example 3

[0076] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 1, a tension spring 233 is fixedly connected between the free ends of the upper stirring rod 231 and the lower stirring rod 232. Under the tension limit of the tension spring 233, the upper and lower stirring rods are prevented from being pulled by the tension spring 233, thus preventing them from being thrown outwards without restriction and easily hitting the extraction cylinder 1. Similarly, it can prevent them from hitting the cage.

[0077] When the upper and lower stirring rods are flung apart, the tension spring 233 is stretched, thereby preventing the upper stirring rod 231 and the lower stirring rod 232 from flung apart indefinitely.

[0078] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
