Description

Technical Field

[0001] This utility model belongs to the field of steviol glycoside production technology, specifically relating to a steviol glycoside production residue extrusion device. Background Technology

[0002] Steviosides possess excellent properties such as high temperature resistance, acid and alkali resistance, and resistance to mold growth. They are readily soluble in water with high solubility, exceeding 40% at room temperature. Furthermore, steviol glycosides are stable in acidic and salt solutions and remain relatively stable at room temperature.

[0003] Juice Residue Issues: During the extrusion process, due to improper design or operation of the extrusion device, the juice in the raw material may not be fully extracted, resulting in a large amount of juice remaining in the residue. This not only reduces the extraction efficiency of steviol glycosides but also increases the difficulty and cost of subsequent processing. Unsatisfactory Extrusion Effects: Existing extrusion devices may not provide sufficient pressure or have uneven extrusion force distribution, resulting in the inability to effectively squeeze out the juice from the raw material. In addition, the structural design of the extrusion device may also affect the juice extraction efficiency, such as the fit between the extrusion plate and the inner wall of the box, the distribution and number of extrusion balls, etc. Poor Discharge Issues: During the extrusion process, due to the high viscosity of the residue or unreasonable design of the extrusion device, poor discharge may occur. This not only affects production efficiency but may also cause equipment blockage and damage. Outlet Blockage: The design or size of the outlet may not meet the actual needs, making it easy for the residue to block during discharge. In addition, if the outlet lacks an effective cleaning and maintenance mechanism, it may also exacerbate the blockage problem. Utility Model Content

[0024] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0025] A slag extrusion device for steviol glycoside production, comprising,

[0026] Sealing cylinder 1;

[0027] The extrusion assembly is located on the inner wall of the sealing cylinder 1. The extrusion assembly includes a rotating frame 5, a limiting groove 501, a suspension frame 6, a filter screen 7, an extrusion roller 8, a scraper 9, a roller 10, a moving block 11, and a fine-tuning component. The suspension frame 6 is fixedly installed on the inner wall of the sealing cylinder 1 by a bracket. The rotating frame 5 is rotatably embedded in the inner wall of the suspension frame 6. The filter screen 7 is embedded in the inner wall of the suspension frame 6. The extrusion roller 8 is rotatably inserted into the protruding ends of two of the moving blocks 11. The scraper 9 is sleeved on the protruding ends of the remaining two moving blocks 11. The roller 10 is sleeved on the outer wall of the moving block 11 and is rotatably embedded in the inner wall of the limiting groove 501. The limiting groove 501 is opened on the outer wall of the rotating frame 5. The fine-tuning component is located on the outer wall of the rotating frame 5. The scraper 9 and the filter screen 7 are matched with each other. A base 101 is fixedly installed at the bottom of the outer wall of the sealing cylinder 1. Sealing covers 2 are slidably embedded on both sides of the outer wall of the sealing cylinder 1.

[0028] In a specific embodiment of this utility model, the extrusion assembly enables efficient multiple extrusions of the residue used in steviol glycoside production, maximizing the separation of raw material juice and residue. This avoids incomplete separation of residue due to single extrusion, which ultimately leads to low steviol glycoside extraction rates and significant raw material waste. First, the base 101 and sealing cylinder 1 are deployed to the designated working position. The feeding device continuously supplies the material to the feeding pipe 3. Then, the residue is collected using the discharge pipe 4. When a specified amount of raw material falls to the center of the bottom of the inner wall of the filter screen 7, an external motor drives the rotating frame 5 to reciprocate, causing the extrusion roller 8 to continue extruding the raw material. The juice falls through the filter screen 7 to the bottom of the inner wall of the sealing cylinder 1 and is collected through a pipe. After the residue is squeezed dry, the rotating frame 5 continues to rotate, causing the scraper 9 to rotate at high speed. The scraper 9 scrapes the filter screen 7 and then concentrates and shovels the residue, concentrating it into the discharge pipe 4. The process continues after the residue is discharged.

[0029] Specifically, the fine-tuning components include a lead screw 12, a limiting frame 13, and a protective housing 14.

[0030] In a specific embodiment of this utility model, the fine-tuning component can adjust the working distance of the extrusion roller 8, thereby adjusting the extrusion pressure on the filter screen 7.

[0031] Specifically, the limiting frame 13 is fixedly installed on the outer wall of the rotating frame 5, and the moving block 11 is slidably embedded in the inner wall of the limiting frame 13.

[0032] In a specific embodiment of this utility model, the moving block 11 is slidably embedded in the inner wall of the limiting frame 13, which can ensure its movement accuracy.

[0033] Specifically, the lead screw 12 is rotatably embedded in the inner wall of the limiting frame 13.

[0034] In a specific embodiment of this utility model, the lead screw 12 is rotatably embedded in the inner wall of the limiting frame 13, which can ensure its movement accuracy.

[0035] Specifically, one end of the lead screw 12 is threaded to the inner wall of the moving block 11, and the protective shell 14 is fixedly installed on the outer wall of the rotating frame 5. The slot of the protective shell 14 matches the moving block 11.

[0036] In a specific embodiment of this utility model, the slot of the protective shell 14 matches the moving block 11, which can achieve stable protection of the lead screw 12.

[0037] Specifically, the outer wall of the sealing cylinder 1 is embedded with a feed pipe 3 and a discharge pipe 4. One end of the feed pipe 3 and the discharge pipe 4 are connected to the inner wall of the filter screen 7, and the scraper 9 is matched with the discharge pipe 4.

[0038] In a specific embodiment of this utility model, the scraper 9 and the discharge pipe 4 are matched to ensure the discharge of residue.

[0039] Working principle:

[0040] The extrusion assembly enables efficient multiple extrusions of the raw material residue for steviol glycoside production, maximizing the separation of raw material juice and residue. This avoids incomplete separation caused by single extrusion, which leads to low steviol glycoside extraction rates and significant raw material waste. First, the base 101 and sealing cylinder 1 are deployed to the designated working position. The feeding device continuously supplies material to the feeding pipe 3, and then the residue is collected using the discharge pipe 4. When a specified amount of raw material falls to the bottom center of the inner wall of the filter screen 7, an external motor drives the rotating frame 5 to reciprocate, causing the extrusion roller 8 to continue extruding the raw material. The juice falls through the filter screen 7 to the bottom of the inner wall of the sealing cylinder 1 and is collected through a pipe. After the residue is squeezed dry, the rotating frame 5 continues to rotate, causing the scraper 9 to rotate at high speed. The scraper 9 scrapes the filter screen 7 and then concentrates and shovels the residue, directing it to the discharge pipe 4. The process continues after the residue is discharged.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
