Description

Technical Field

[0001] The present invention relates to the field of mixing technology, in particular to a ventilation mixer for theanine production. Background Art

[0002] Theanine is an amide compound that has many important physiological functions and is therefore widely used in food, health products and pharmaceutical industries.

[0003] Currently, there are many methods for producing theanine, at least one of which utilizes an enzymatic reaction to obtain theanine. For example, a method for extracting and purifying theanine through an enzymatic reaction, disclosed in Authorization Publication No. CN114213276B, requires stirring and extracting an ethanol-water solution. Therefore, a mixer is an essential and important piece of equipment for theanine production.

[0004] However, although there are many types of mixers currently available, the feed port is mostly set at the top of the mixer, and the feeding channels of various materials (such as ethanol and aqueous solution) all enter the mixer through one feed port. Therefore, the feeding method is single, especially the materials added to the mixer later, which are difficult to achieve faster mixing with other materials at multiple angles, affecting the mixing efficiency between the materials.

[0005] Secondly, when the agitator of the current mixer is stirring, the material in 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), affecting the mixing efficiency of the material. Although spoilers have been added to the mixer, the effect of the spoiler on the mixing of materials is difficult to achieve the expected effect. Therefore, further improvement is needed.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] Example 1:

[0055] like Figure 1-Figure 3 As shown, the present invention discloses a ventilation mixer for theanine production, comprising:

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

[0057] The stirrer 20 is rotatably disposed within the body 10, and a driving unit 21 for controlling the rotation of the stirrer 20 is mounted on the body 10. The stirrer 20 comprises a stirring shaft 200 whose rotation is controlled by the driving unit 21 and a stirring blade 201 mounted on the stirring shaft 200. The stirrer 20 also includes an adding mechanism mounted on the body 10, the adding mechanism comprising:

[0058] The addition pipe 30 is disposed in the stirring chamber 100 and has an addition cavity;

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

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

[0061] The adding chamber is provided with a piston shaft that can be controlled by a driving device to reciprocate. When the piston shaft reciprocates, negative pressure is formed in the adding chamber and the solvent is sucked in from the feed pipe and added to 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 which are spaced apart;

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

[0065] A connecting shaft 43 connected to the second piston shaft 42 and capable of being inserted into the telescopic cavity 41a;

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

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

[0068] Among them, the feed pipe includes a first inlet pipe 321 and a second inlet pipe 322, the discharge pipe includes a first row of pipes 311 and a second row of pipes 312, and an air cavity connected to the first inlet pipe 321 and the first row of pipes 311 is formed between the first piston shaft 41 and the second piston shaft 42; a liquid cavity connected to the second inlet pipe 322 and the second row of pipes 312 is formed between the first piston shaft 41 and the addition pipe 30.

[0069] In this embodiment, one-way valves are provided on the first inlet pipe, the second inlet pipe, the first row of pipes and the second row of pipes. The one-way valves can enable one-way flow of the airflow and the solvent, that is, the gas enters the gas cavity from the first inlet pipe and flows into the stirring cavity through the first row of pipes in one direction, and the solvent enters the liquid cavity from the second inlet pipe and flows into the stirring cavity through the second row of pipes in one direction.

[0070] In this embodiment, the driving structure is a hydraulic cylinder, and the driving end of the hydraulic cylinder 6 (the piston rod of the hydraulic cylinder) passes through the body and the addition 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 body and the driving end of the hydraulic cylinder and the addition pipe can be sealed to ensure the sealing of the body and the addition pipe.

[0071] In this embodiment, a pressure relief valve 5 is provided on the machine body 10 .

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

[0073] refer to Figure 1-Figure 3 , the principle of this embodiment is:

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

[0075] In this embodiment, gas can be provided to the gas cavity through the first inlet pipe. In this embodiment, it is recommended to use inert gas to avoid the possibility of ethanol oxidation. At the same time, dry gas (without moisture) should be used as the main gas 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 evaporated material obtained by evaporating the clarified liquid) is added to the stirring chamber through the feed nozzle, and then the driving unit is started at the same time to control the stirrer to stir the theanine raw material in the stirring chamber. At the same time, the hydraulic cylinder starts to control the first piston shaft and the second piston shaft to move up and down and reciprocatingly in the extrusion tube; when the first piston shaft reciprocates, negative pressure is continuously formed in the liquid chamber, and ethanol aqueous solution is introduced from the second inlet pipe and enters the extrusion chamber through the second row of pipes; when the second piston shaft reciprocates, especially when the first piston shaft has moved to the bottom of the extrusion tube, at this time, when the second piston shaft continues to descend, the gas in the gas chamber will be squeezed out from the first row of pipes and enter the stirring chamber.

[0077] In the above process, ethanol 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 the theanine raw material. In addition, when the first row of pipes is exhausted, the air flow flowing in the mixed liquid 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 limit spring. When the first piston shaft and the second piston shaft move, the first piston shaft moves to the bottom of the extrusion tube first to ensure that the ethanol-water solution can be completely discharged. Then the second piston shaft gradually compresses the limit spring and squeezes out the airflow in the air cavity. In this way, 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 from the air cavity first, the stirring chamber will construct an airflow discharge path through the air cavity and the pressure relief valve, and the theanine raw material will be discharged from the pressure relief valve. Therefore, this embodiment can avoid the occurrence of this phenomenon.

[0079] During the specific implementation of this embodiment, the first piston shaft is first reciprocated, and a sufficient amount of ethanol-water solution is first introduced into the stirring chamber through the liquid chamber. When the theanine raw material and the ethanol-water solution are easily extruded in the required ratio, the solution in the stirring chamber is at least higher than the first row of tubes, so that the airflow discharged from the first row of tubes can assist in mixing the materials in the stirring chamber.

[0080] Example 2 is different from Example 1 in that:

[0081] like Figure 4-Figure 7 As shown, in this embodiment, a receiving chamber 70 for mounting the drive unit 21 and having an open top is formed on the frame 10a of the machine body 10. The machine body 10 is further provided with two air bleed chambers 71 located on both sides of the receiving chamber 70. A chassis is mounted on the frame 10a. The chassis consists of a box body 720 and a box cover 721. The receiving chamber and the air bleed chamber are formed on the chassis. The driving structure includes:

[0082] The piston plate 80 moves in the air inlet chamber 71 and is connected to the second piston shaft 42 via a linkage shaft 81;

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

[0084] The cam 84 is horizontally arranged and rotatably connected between the inner walls of the air inlet chamber 71 through the transmission shaft 85, and the side wall contacts the piston plate 80;

[0085] The chassis is further provided with a one-way air inlet valve 73 and a one-way air exhaust valve 74 that can communicate with the air inlet cavity 71 , and the output end of the one-way air exhaust valve 74 is communicated with the accommodating cavity 70 ;

[0086] The transmission shaft 85 is controlled to rotate by the motor 75 installed on the chassis.

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

[0088] In this embodiment, two air bleed chambers 71 and two addition pipes 30 are provided, and the piston plate 80 in each air bleed chamber 71 extends longitudinally and can reciprocate horizontally within the air bleed chamber 71. A synchronization structure for controlling the synchronous movement of the cams 84 is also mounted on the frame 10a of the machine body.

[0089] When the cams 84 move synchronously, materials are supplied synchronously into the stirring chamber 100 through the discharge pipes.

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

[0091] The pulley 90 is connected to the cam via the transmission shaft 91;

[0092] A transmission belt 91 is driven between pulleys 90;

[0093] The arbitrary pulley 90 is controlled to rotate by the motor 75 .

[0094] In this embodiment, a movable cavity for the transmission belt to pass through is provided on the chassis, and the movable cavity is spaced apart from the accommodating cavity.

[0095] In this embodiment, the jetting direction of the first row of pipes 311 is opposite to the rotation direction of the agitator.

[0096] refer to Figure 4-Figure 7 , the principle of this embodiment is:

[0097] This embodiment provides two addition tubes (based on this embodiment, providing more than two addition tubes should also be within the scope of protection of the present invention, and the distribution of multiple addition tubes can be circumferentially distributed based on the axis of the stirring chamber). Taking two addition tubes as an example, the present invention provides a chassis on the frame, and a synchronization structure is provided on the chassis. In more detail, when the motor controls the rotation of any pulley, the transmission belt drives each pulley to run synchronously, and drives each cam to move.

[0098] When the cam moves, the cam cooperates with the return spring to make the piston plate reciprocate in the air inlet chamber, thereby controlling the linkage shaft to control the first piston shaft and the second piston shaft in the addition tube to move up and down reciprocatingly through the guide inclined plate and the support spring on the piston plate, thereby introducing air flow from the air chamber into the stirring chamber, and introducing solvent from the liquid chamber into the stirring chamber.

[0099] When using this embodiment, the corresponding solvent and theanine raw material are prepared in proportion. Part of the solvent and theanine raw material can be added to the stirring chamber through the feed nozzle in sequence, and the remaining solvent is sent into the stirring chamber through the second inlet pipe, and the first inlet pipe is used to assist in the mixing of the materials in the stirring chamber. Although part of the solvent and theanine raw material are added to the stirring chamber through the feed nozzle in this embodiment, the remaining solvent will still be insufficient to enter the stirring chamber through the second inlet pipe, and the solvent entering the stirring chamber from the liquid chamber can still improve the mixing efficiency in the stirring chamber. Moreover, since multiple addition tubes are provided, the number of turbulent surfaces is also increased, so the mixing efficiency will be more prominent than that of Example 1.

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

[0101] In addition, another usage of this embodiment is:

[0102] There is no liquid cavity in the addition tube, and both are air cavities. That is to say, the solvent and theanine raw material can be added to the stirring chamber together through the feed nozzle, and the air flow is introduced into the stirring chamber through the air cavity of the addition tube to assist in material mixing. At the same time, the one-way air inlet valve and the one-way exhaust valve provided on the chassis can introduce gas into the air inlet cavity when the piston plate moves and discharge it into the accommodating cavity from the one-way exhaust valve, thereby dissipating heat to the driving unit. This embodiment allows the air cavity to continuously supply air to the stirring chamber without considering that it will affect the ratio of the solvent and theanine raw material, and can also dissipate heat to the driving 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 in the scope of protection of the present invention.
