Stirring paddle for flavor and fragrance production

Abstract

This utility model relates to the field of agitator technology and discloses an agitator for fragrance and flavor production, including a shaft with two sets of blades fixedly mounted on it. These two sets of blades propel material convection. The two sets of blades can work together to form a powerful, directional fluid circulation. The upper blades push the fluid downwards, while the lower blades push it upwards, creating a strong vertical convection circulation loop within the entire tank. This effectively prevents solid particles from settling and accumulating at the bottom of the tank, maintaining a uniform suspension for extended periods, ensuring product consistency and stability, and thus improving energy utilization.

Description

Technical Field

[0001] This utility model relates to the field of stirring paddle technology, specifically a stirring paddle for the production of fragrances and flavorings. Background Technology

[0002] In the fragrance and flavor industry, product quality is highly dependent on its uniformity, stability, and sensory characteristics (such as color, aroma, and taste). Mixing is one of the core steps in production, and the design of the mixing paddle directly determines the efficiency, effectiveness, and final product quality of the mixing process.

[0003] Existing agitators transfer mechanical energy to the fluid through their rotation, thereby generating various forms of flow within the fluid and ultimately achieving mixing. However, during the rotation of the agitator, the solution inside the tank can only flow in one direction. Mixing is achieved by the unidirectional flow of the solution impacting the inner wall of the tank. The fluid, like a solid, undergoes a circular motion along with the agitator blades, with almost no relative velocity or shear between layers. Mixing mainly relies on the impact force of the impact on the tank wall. To achieve the desired mixing effect, the agitation speed must be significantly increased, which leads to a sharp increase in energy consumption and energy waste. Utility Model Content

[0004] The purpose of this invention is to provide a stirring paddle for the production of fragrances and flavors, which solves the problem of low energy utilization caused by the material mainly relying on the impact force of hitting the tank wall for mixing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a stirring paddle for the production of fragrances and flavors, including a shaft body, on which two sets of blades are fixedly installed, and the two sets of blades promote the convection of materials.

[0007] Furthermore, the blade assembly includes a sleeve fitted onto the shaft, and the outer surface of the sleeve is provided with two sets of helical blades and a set of rods. Furthermore, a spacer is fitted between the two sets of blade assemblies, and the length of the spacer is selected according to the usage requirements.

[0008] Furthermore, the outer surface of the spacer is provided with a plurality of vertically distributed plates, which are distributed radially along the spacer.

[0009] Furthermore, two sets of extension components are installed on the shaft, which push the material toward the central axis position.

[0010] Furthermore, the extension includes a tube seat sleeved on the shaft, on which two inclined blades are fixed, with the two sets of inclined blades located outside the blade sets.

[0011] Furthermore, a limiting member is installed on the shaft to limit the movement of the extension.

[0012] This utility model has the following beneficial effects:

[0013] The two sets of blades in this invention can work together to form a powerful, directional fluid circulation. The upper blade set presses the fluid downwards, while the lower blade set pushes the fluid upwards, thus creating a strong vertical convection circulation loop throughout the tank. This effectively prevents solid particles from settling and accumulating at the bottom of the tank, keeping them in a uniformly suspended state for a long time, ensuring product consistency and stability, and thereby improving energy utilization.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the fragrance and flavor industry, product quality is highly dependent on its uniformity, stability, and sensory characteristics (such as color, aroma, and taste). Mixing is one of the core steps in production, and the design of the mixing paddle directly determines the efficiency, effectiveness, and final product quality of the mixing process.

[0026] Existing agitators transfer mechanical energy to the fluid through their rotation, thereby generating various forms of flow within the fluid and ultimately achieving mixing. However, during the rotation of the agitator, the solution inside the tank can only flow in one direction. Mixing is achieved by the unidirectional flow of the solution impacting the inner wall of the tank. The fluid, like a solid, undergoes a circular motion along with the agitator blades, with almost no relative velocity or shear between layers. Mixing mainly relies on the impact force of the impact on the tank wall. To achieve the desired mixing effect, the agitation speed must be significantly increased, which leads to a sharp increase in energy consumption and energy waste.

[0027] Please see Figs. 1-2 As shown, this utility model is a stirring paddle for the production of fragrances and flavors, including a shaft 1, on which two sets of blades 2 are fixedly installed, and the two sets of blades 2 promote the convection of materials; the shaft 1 includes a cylindrical structure and a prism structure, and the blades 2 are sleeved on the prism structure and fixed by welding, thereby realizing the synchronous rotation of the shaft 1 and the blades 2.

[0028] The two sets of blades 2 can work together to form a powerful, directional fluid circulation. The upper set of blades 2 pushes the fluid downwards, while the lower set of blades 2 pushes the fluid upwards, thus forming a strong vertical convection circulation loop throughout the tank.

[0029] It can effectively prevent solid particles from settling and accumulating at the bottom of the tank, keeping them in a uniform suspension state for a long time, thus ensuring the consistency and stability of the product.

[0030] The blade assembly 2 includes a sleeve 201 fitted onto the shaft 1. Two sets of spiral blades 202 and a set of rods 203 are provided on the outer surface of the sleeve 201. The set of rods 203 is located between the two sets of spiral blades 202.

[0031] The spiral blades 202 on a single sleeve 201 are divided into two groups. When the material is moved, the material passes through the rod 203. After the material and the particles it contains impact the rod 203, the particles are crushed and the mixing effect is improved.

[0032] A spacer 3 is fitted between the two sets of blades 2. The length of the spacer 3 is selected according to the usage requirements. The height H formed by the two sets of blades 2 and the spacer 3 is selected according to the height h of the solution inside the tank, where H≤h.

[0033] Both the blade assembly 2 and the spacer 3 can be made of stainless steel, thereby improving the overall corrosion resistance of the structure.

[0034] like Figs. 3-4 As shown, several vertically distributed plates 301 are provided on the outer side of the spacer 3. The plates 301 are distributed radially along the spacer 3. The spacer 3 rotates synchronously with the shaft 1, and the plates 301 push the middle layer material to diffuse outward.

[0035] like Figs. 5-6 As shown, two sets of extension parts 4 are installed on the shaft 1, and the extension parts 4 push the material to move towards the central axis position.

[0036] The extension 4 includes a tube seat sleeved on the shaft 1, and two inclined blades 401 are fixed on the tube seat. The two sets of inclined blades 401 are located outside the blade set 2.

[0037] A limiting member 5 is installed on the shaft 1 to limit the extension member 4;

[0038] The function of the limiting part 5 is to ensure the reliable realization of the function of the extension part 4 and to prevent the extension part 4 from moving up and down on the shaft 1. The limiting part 5 can be a nut, which is installed in conjunction with the external thread on the shaft 1.

[0039] As the extension 4 rotates with the shaft 1, the inclined blade 401 pumps the material on the outside and pushes it toward the central axis, solving the problem that the blades have difficulty driving the material flow at the tank wall.

[0040] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
