Description

Technical Field

[0001] This invention relates to the field of mixing technology, and in particular to a ventilated mixer for the production of theanine. Background Technology

[0002] Theanine is an amide compound with a variety of important physiological functions, and is therefore widely used in the food, health products and pharmaceutical industries.

[0003] Currently, there are many methods for producing theanine, at least one of which utilizes an enzyme-catalyzed reaction to obtain theanine. For example, the method for extracting and purifying theanine from an enzyme-catalyzed reaction disclosed in patent announcement number CN114213276B requires stirring and extraction with an ethanol-water solution. Therefore, a stirrer is an indispensable piece of equipment for theanine production.

[0004] However, although there are many types of mixers available, the feed inlet is usually located at the top of the mixer. All materials (such as ethanol-water solutions) enter the mixer through a single feed inlet. Therefore, the feeding method is limited, especially for materials added to the mixer later. It is difficult to achieve rapid mixing with other materials from multiple angles, which affects the mixing efficiency between materials.

[0005] Secondly, when the agitator of the current mixer is stirring, the material inside the mixer rotates synchronously with the agitator, which easily forms a "vortex" and produces a solid rotation phenomenon (referring to the phenomenon that the fluid rotates as a whole like a rigid body in the container), which affects the mixing efficiency of the material. Although baffles have been added to the mixer, the effect of the baffles on the mixing of the material is difficult to achieve as expected. Therefore, further improvements are needed. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a ventilated mixer for theanine production, which aims to solve the problems mentioned in the background technology.

[0007] The technical solution of this invention is implemented as follows: a ventilated agitator for theanine production, comprising:

[0008] The machine body has a mixing chamber and is equipped with a feed nozzle and a discharge nozzle.

[0009] A stirrer is rotatably mounted inside the machine body, and a drive unit for controlling the rotation of the stirrer is installed on the machine body. The machine body also includes an additive mechanism, which comprises:

[0014] By adopting the above technical solution:

[0015] This invention installs an additive mechanism inside the mixing chamber of a mixer. This additive mechanism adds a path for the solvent to enter the mixer. Unlike the prior art, the additive mechanism of this invention is located inside the machine body and allows the solvent to enter the mixing chamber in a radial direction, thereby enabling the solvent and other materials to mix quickly and increasing the mixing efficiency.

[0028] The drive shaft is rotated by a motor mounted on the machine body.

[0029] By adopting the above technical solution:

[0030] The feeding tube of the present invention controls the feeding through a piston shaft set inside it. When the piston shaft moves, a negative pressure is formed inside the extrusion tube to achieve feeding through the extrusion tube, and the solvent is squeezed into the stirring chamber by the piston shaft.

[0031] Furthermore, this invention can supply air into the mixing chamber using the air chamber while feeding materials, using the airflow to assist mixing and increase mixing efficiency; while the induced air can introduce gas to cool the drive unit of the agitator.

[0053] 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.

[0054] Example 1:

[0055] like Figures 1-3 As shown, this invention discloses a ventilated mixer for theanine production, comprising:

[0056] The machine body 10 has a mixing chamber 100, and is provided with a feed nozzle 101 and a discharge nozzle 102, and is supported by a bracket 10a. Both the feed nozzle 101 and the discharge nozzle 102 are control valves, and a material pipe (for feeding or discharging) is connected to the feed nozzle 101 and the discharge nozzle 102.

[0057] A stirrer 20 is rotatably disposed within a machine body 10, and a drive unit 21 for controlling the rotation of the stirrer 20 is mounted on the machine body 10. The stirrer 20 consists of a stirring shaft 200 whose rotation is controlled by the drive unit 21 and stirring blades 201 mounted on the stirring shaft 200. It also includes an additive mechanism mounted on the machine body 10, the additive mechanism comprising:

[0058] The addition tube 30 is located inside the stirring chamber 100 and has an addition chamber;

[0059] The discharge pipe is located on the addition pipe 30 and is equipped with a first one-way valve 31a;

[0060] The feed pipe is located on the machine body 10, communicates with the addition chamber, and is equipped with a second one-way valve 32a;

[0061] The addition chamber is equipped with a piston shaft that can be controlled to reciprocate by a driving device. When the piston shaft reciprocates, it can create a negative pressure in the addition chamber and draw in the solvent from the feed pipe, and add it into the stirring chamber 100 from the discharge pipe.

[0062] In this embodiment: the driving device includes:

[0063] The piston shaft is composed of a first piston shaft 41 and a second piston shaft 42 that are spaced apart.

[0064] The telescopic cavity 41a is formed at one end of the first piston shaft 41 near the second piston shaft 42;

[0065] The connecting shaft 43 is connected to the second piston shaft 42 and can be inserted into the telescopic cavity 41a;

[0066] A limiting spring 44 is connected between the first piston shaft 41 and the second piston shaft 42;

[0067] The drive structure is mounted on the machine body and is used to control the lifting and lowering of the piston shaft;

[0068] The feed pipe includes a first feed pipe 321 and a second feed pipe 322, the discharge pipe includes a first discharge pipe 311 and a second discharge pipe 312, and an air chamber is formed between the first piston shaft 41 and the second piston shaft 42, which communicates with the first feed pipe 321 and the first discharge pipe 311; a liquid chamber is formed between the first piston shaft 41 and the addition pipe 30, which communicates with the second feed pipe 322 and the second discharge pipe 312.

[0069] In this embodiment, one-way valves are provided on the first inlet pipe, the second inlet pipe, the first row pipe, and the second row pipe. The one-way valves allow for unidirectional flow of gas and solvent, i.e., gas enters the gas chamber from the first inlet pipe and enters the stirring chamber through the first row pipe, and solvent enters the liquid chamber from the second inlet pipe and enters the stirring chamber through the second row pipe.

[0070] In this embodiment, the driving structure is a hydraulic cylinder. The driving end of the hydraulic cylinder 6 (which is the piston rod of the hydraulic cylinder) passes through the machine body and the adding pipe in sequence and is connected to the second piston shaft. The mating surfaces of the driving end of the hydraulic cylinder 6 and the machine body, as well as the driving end of the hydraulic cylinder and the adding pipe, can be sealed to ensure the sealing performance of the machine body and the adding pipe.

[0071] In this embodiment: the body 10 is provided with a pressure relief valve 5.

[0072] In this embodiment: the addition tube 30 is integrally formed with the body 10, and the addition tube 30 forms a curved turbulence surface 300a with the inner wall of the stirring chamber, which can prevent solid rotation.

[0073] refer to Figures 1-3 The principle of this embodiment is:

[0074] In this embodiment, a solvent, such as an aqueous ethanol solution, can be supplied to the liquid chamber through a second inlet pipe.

[0075] In this embodiment, gas can be supplied to the gas chamber through the first inlet pipe. In this embodiment, it is recommended to use an inert gas to avoid the possibility of ethanol oxidation. At the same time, dry gas (free of moisture) should be used as much as possible to avoid affecting the extraction effect.

[0076] After all the above conditions are prepared, the theanine raw material (such as the clarified liquid obtained by enzyme catalysis and filtration, and the dried product obtained by evaporation of the clarified liquid) is added into the stirring chamber through the feed nozzle. Then, the drive unit is started to control the stirrer to stir the theanine raw material in the stirring chamber. At the same time, the hydraulic cylinder is started to control the first piston shaft and the second piston shaft to move up and down and reciprocate in the extrusion tube. When the first piston shaft moves back and forth, a negative pressure is continuously formed in the liquid chamber, and an ethanol aqueous solution is introduced from the second inlet pipe and enters the extrusion chamber through the second outlet pipe. When the second piston shaft moves back and forth, especially when the first piston shaft has moved to the bottom of the extrusion tube, the second piston shaft continues to descend, which will squeeze the gas in the gas chamber out from the first outlet pipe and enter the stirring chamber.

[0077] In the above process, ethanol and water can easily enter from the side, and the stirring of the theanine raw material by the stirrer can improve the mixing efficiency of the solvent and theanine raw material. In addition, when the first exhaust pipe is vented, the airflow in the mixture of theanine raw material and solvent can increase the mixing efficiency of the two, thereby improving the extraction efficiency.

[0078] It is worth mentioning that in this embodiment, the first piston shaft and the second piston shaft are connected by a limiting spring. When the first piston shaft and the second piston shaft move, the first piston shaft moves first to the bottom of the extrusion tube to ensure that all the ethanol-water solution can be discharged. Then, the second piston shaft gradually presses the limiting spring and squeezes out the airflow in the gas chamber. This ensures that when the gas is discharged, there is already enough ethanol-water solution in the stirring chamber. Therefore, the gas can be used to promote the mixing of the ethanol-water solution and theanine raw material. If the gas is discharged first from the gas chamber, the stirring chamber will form an airflow discharge path through the gas chamber and the pressure relief valve, resulting in the theanine raw material being discharged from the pressure relief valve. Therefore, this embodiment can avoid the occurrence of this phenomenon.

[0079] In this embodiment, the first piston shaft is reciprocated, and a sufficient amount of ethanol-water solution is introduced into the stirring chamber through the liquid chamber. To meet the requirements of the ratio of theanine raw material to ethanol-water solution during extrusion, the solution in the stirring chamber is at least higher than the first row of pipes. In this way, the airflow discharged from the first row of pipes can assist in the mixing of materials in the stirring chamber.

[0080] Example 2 differs from Example 1 in that:

[0081] like Figures 4-7 As shown, in this embodiment, a receiving cavity 70 for mounting the drive unit 21 and with an open top is formed on the frame 10a of the body 10. The body 10 also has two air ducts 71 located on either side of the receiving cavity 70. A chassis is mounted on the frame 10a, consisting of a box body 720 and a box cover 721. The receiving cavity and air ducts are formed on the chassis. The drive structure includes:

[0082] Piston plate 80 is movable within air venting chamber 71 and is connected to second piston shaft 42 via linkage shaft 81;

[0083] A return spring 82 is connected between the piston plate 80 and the air duct 71. A spring cavity is formed on the piston plate 80, and a positioning post 83 that can move in the spring cavity is provided in the air duct 71. The return spring is located in the spring cavity and is connected between the positioning post 83 and the spring cavity.

[0084] Cam 84 is horizontally positioned and rotatably connected to the inner wall of air duct 71 via transmission shaft 85, with its side wall in contact with piston plate 80.

[0085] The chassis is also equipped with a one-way air intake valve 73 and a one-way exhaust valve 74 that can communicate with the air intake chamber 71. The output end of the one-way exhaust valve 74 is connected to the receiving chamber 70.

[0086] The drive shaft 85 is rotated by a motor 75 mounted on the chassis.

[0087] In this embodiment, the piston plate 80 is provided with a guide ramp 80a, and a support spring 81a is provided between the linkage shaft 81 and the air duct 71, and the support spring 81a causes one end of the linkage shaft 81 to abut against the guide ramp 80a.

[0088] In this embodiment, there are two air intake chambers 71 and two adding tubes 30, and the piston plate 80 in each air intake chamber 71 extends longitudinally and can move horizontally back and forth in the air intake chamber 71; wherein, a synchronization structure for controlling the synchronous movement of each cam 84 is also installed on the frame 10a of the machine body.

[0089] When the cam 84 moves synchronously, it feeds material into the mixing chamber 100 synchronously through each discharge pipe.

[0090] In this embodiment, the synchronization structure includes:

[0091] Pulley 90 is connected to cam via drive shaft 91;

[0092] The drive belt 91 drives the transmission between pulleys 90;

[0093] In this configuration, any pulley 90 is controlled to rotate by the motor 75.

[0094] In this embodiment, the chassis is provided with a movable cavity through which the drive belt passes, and the movable cavity and the receiving cavity are spaced apart.

[0095] In this embodiment, the jet direction of the first pipe 311 is opposite to the rotation direction of the stirrer.

[0096] refer to Figures 4-7 The principle of this embodiment is:

[0097] This embodiment sets up two addition tubes (based on this embodiment, setting up more than two addition tubes should also be within the protection scope of this invention, and the distribution of multiple addition tubes can be circumferentially distributed with the axis of the stirring chamber as the reference). Taking two addition tubes as an example, this invention sets up a chassis on the frame, and sets up a synchronization structure on the chassis. More specifically, when the motor controls any pulley to rotate, the transmission belt drives each pulley to run synchronously and drives each cam to move.

[0098] When the cam moves, the cam and the return spring work together to make the piston plate reciprocate in the air intake chamber. The guide plate and the support spring on the piston plate work together to control the linkage shaft to control the reciprocating movement of the first piston shaft and the second piston shaft in the addition tube. This allows airflow to be introduced from the air chamber into the stirring chamber and solvent to be introduced from the liquid chamber into the stirring chamber.

[0099] In this embodiment, the appropriate solvent and theanine raw material are prepared in proportion. Part of the solvent and theanine raw material can be added to the mixing chamber through the feed nozzle, while the remaining solvent is fed into the mixing chamber through the second inlet pipe. Air is introduced into the mixing chamber through the first inlet pipe to assist the mixing of materials in the mixing chamber. Although part of the solvent and theanine raw material are added to the mixing chamber through the feed nozzle in this embodiment, the remaining solvent will still be insufficient to enter the mixing chamber through the second inlet pipe. The solvent entering the mixing chamber from the liquid chamber can still improve the mixing efficiency in the mixing chamber. Furthermore, due to the setting of multiple addition pipes, the number of turbulence surfaces is also increased. Therefore, the mixing efficiency is more outstanding than that of Embodiment 1.

[0100] Secondly, the air outlet direction of the first row of pipes in this embodiment is opposite to the rotation direction of the stirrer, as shown in the reference. Figure 7 The stirring gas can rotate clockwise, and the gas outlet of the first row of pipes sprays gas counterclockwise to further disrupt the movement of materials in the stirring chamber and improve the mixing efficiency.

[0101] In addition, another way to use this embodiment is:

[0102] The addition tube does not have a liquid chamber; instead, both chambers are air chambers. This means that the solvent and theanine raw material can be added to the mixing chamber together through the feed nozzle. Airflow is then introduced into the mixing chamber through the air chamber of the addition tube to assist in material mixing. At the same time, the one-way inlet valve and one-way outlet valve on the chassis can introduce gas into the priming chamber when the piston plate moves and discharge it into the receiving chamber through the one-way outlet valve, thereby cooling the drive unit. This embodiment allows the air chamber to continuously supply air to the mixing chamber without affecting the ratio of solvent and theanine raw material, while also cooling the drive unit.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
