Description

Technical Field

[0001] This invention relates to the field of food testing technology, and in particular to a tissue homogenizer for testing bulbous vegetables. Background Technology

[0002] A tissue homogenizer for food testing is a laboratory device specifically designed to rapidly and uniformly mix, break down, emulsify, and homogenize food samples with extraction solutions to prepare representative, homogeneous test samples. Tissue homogenizers are also used for testing bulbous vegetables.

[0003] Many bulbous vegetables, especially garlic, onions, and lilies, contain natural saponins. Saponins are natural surfactants; when their aqueous solutions are vigorously stirred, they produce abundant, stable, and persistent foam, which can lead to the following problems:

[0004] 1) Volume error: Foam will occupy the liquid volume, resulting in inaccurate volume determination, which directly affects the concentration calculation of subsequent tests (such as pesticide residues, heavy metal analysis);

[0005] 2) Difficulty in sampling: When using a pipette to draw up subsamples, it is very easy to draw in foam, resulting in inaccurate sampling volume;

[0006] Therefore, a tissue homogenizer for detecting bulbous vegetables is proposed to address the above problems. Summary of the Invention

The invention will be further described below in conjunction with specific embodiments.

[0040] Example

[0041] like Figures 1-13 As shown, a tissue homogenizer for detecting bulbous vegetables includes a base 3 and a limiting ring 4. The limiting ring 4 is fixedly connected to the top of the base 3. A lower cylinder 9 is placed inside the limiting ring 4, and the limiting ring 4 limits the lower cylinder 9 to ensure its stability during use. An upper cylinder 10 is spirally connected to the top of the lower cylinder 9. A sample of bulbous vegetables (garlic, onion, lily) and related reagents are placed inside the upper cylinder 10. An end cap 12 is spirally connected to the top of the upper cylinder 10. A connecting shaft 13 is rotatably connected to the inside of the end cap 12. A source inhibition mechanism 1 and an antifoaming mechanism 2 are provided on the outside of the connecting shaft 13.

[0042] Meanwhile, the lower cylinder 9 is narrower at the top and wider at the bottom. When the liquid rotates, it forms a concave vortex. In a traditional cylindrical or wide-at-the-top-narrow-at-the-bottom cup, this vortex would easily extend to the bottom of the cup, like a "straw" drawing air in from the top. By setting the lower cylinder 9 into a conical structure, the "throat" of the vortex is narrowed due to the small top cross-section, making it difficult for the vortex to develop. At the same time, the wide space at the bottom disperses the kinetic energy of the fluid, further weakening the intensity of the vortex and inhibiting the entrainment of air from the top.

[0043] A vertical rod 5 is fixedly connected to the top of the base 3. A horizontal plate 6 is slidably connected to the outside of the vertical rod 5. A limiting shell 7 is fixedly connected to the top of the horizontal plate 6, and the limiting shell 7 is slidably connected to the vertical rod 5. A second locking screw 8 is spirally connected to the inner side of one end of the limiting shell 7, and the end of the second locking screw 8 is in contact with the vertical rod 5. After the limiting shell 7 moves to a suitable position, the second locking screw 8 can achieve the limiting and fixing between the vertical rod 5 and the limiting shell 7. A motor 11 is fixedly connected to the top of the horizontal plate 6, and the end of the main shaft of the motor 11 is fixedly connected to the connecting shaft 13. The upper cylinder 10 and the lower cylinder 9 need to be spirally connected. When connecting them, first separate the second locking screw 8 from the upright 5, then move the horizontal plate 6 upward via the motor 11, carrying the connecting shaft 13, the source suppression mechanism 1, and the defoaming mechanism 2, so that the lower cylinder 9 can be placed inside the limiting ring 4. Then move the horizontal plate 6 downward, so that the connecting shaft 13, the source suppression mechanism 1, and the defoaming mechanism 2 move to the inside of the lower cylinder 9, and then connect the lower cylinder 9 and the upper cylinder 10 together spirally. The motor 11 can also rotate clockwise inside the lower cylinder 9 via the connecting shaft 13, carrying some components inside the source suppression mechanism 1 and the defoaming mechanism 2 (top view).

[0044] As a further improvement to the present invention, such as Figure 3 and Figure 4 As shown, four baffles 14 are fixedly connected to the inner side of the lower cylinder 9, and they are evenly distributed around the lower cylinder 9. The baffles 14 are provided with sinusoidal "wave surfaces". The crests guide the upper layer of downward-pressed slurry to flow towards the central rotor area, and the troughs receive the lower layer of upward-pressed slurry and diffuse towards the cylinder wall, forming a "center-edge" closed loop. The baffles 14 are inclined at an angle of 15-25° to avoid the baffles 14 forming a "reverse angle" with the cylinder wall, ensuring that the slurry transitions smoothly along the cylinder wall-baffles 14, reducing turbulence, preventing air from being entrained by turbulence, and reducing foam generation.

[0045] Meanwhile, the tilt angle of the baffle 14 can be designed according to the type of bulbous vegetables. For example, for high-viscosity slurry (such as lily and yam slurry): the angle of the baffle 14 is adjusted to 25° to increase the "thrust component" of the baffle 14 on the slurry and prevent the viscous slurry from accumulating on the surface of the baffle 14.

[0046] For low-viscosity, high-moisture slurries (such as onion and garlic homogenates): reduce the angle of the baffle plate from 14° to 15° to weaken the turbulence intensity and prevent the slurry from generating new bubbles due to excessive disturbance.

[0047] As a further improvement to the present invention, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the source suppression mechanism 1 includes a first connecting ring 101 and a second connecting ring 104 sleeved on the outside of the connecting shaft 13. A cutter 102 is fixedly connected to the outside of both the first connecting ring 101 and the second connecting ring 104. The cutter 102 includes a notch 10201, a first guide surface 10202 and a cutting edge 10203. The notch 10201 is opened at the blade of the cutter 102. The notch 10201 serves as a directional guide channel between the cutter 102 and the guide shell 103. It can force the slurry cut by the cutting edge 10203 into the flow path of the first guide surface 10202, preventing the slurry from spreading to the outside of the blade. It ensures that more than 90% of the surface slurry enters the inside of the guide shell 103 through the notch 10201, realizing a continuous flow field of cutting-guiding-convergence, and reducing the liquid surface rolling caused by slurry overflow from the source.

[0048] The first guide surface 10202 is disposed between the cutting edge 10203 and the notch 10201. The first guide surface 10202 is inclined. When the cutter 102 rotates at a high speed of 2000-2500 r / min, the inclined surface will generate a spiral downward directional thrust (the angle between the thrust direction and the horizontal plane is the same as the inclination angle of the guide surface), forcibly pressing the slurry in the surface 10-15 mm range downward along the surface, so that the slurry obtains a downward flow velocity of 0.3-0.5 m / s; at the same time, the first guide surface 10202 02 forms a smooth 15° transition angle with the inlet of notch 10201. When the slurry flows along the surface under the action of thrust, it will naturally flow into the channel of notch 10201 (instead of spreading to the outside of the blade). This ensures that more than 90% of the surface slurry is always in a constrained flow state before entering the guide shell 103, which fundamentally avoids free rolling caused by the slurry leaving the guide surface (the rolling amplitude is reduced from the original design of 5mm to ≤1mm), reduces the amount of air entrainment by more than 60%, and significantly reduces the basis for bubble generation.

[0049] As a further improvement to the present invention, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a guide shell 103 is fixedly connected to the bottom end of the cutter 102. The guide shell 103 includes a second guide surface 10301 and a third guide surface 10302. The guide shell 103 is through-type, and the inlet of the guide shell 103 is connected to the notch 10201 of the cutter 102, so that the slurry can enter the inner side of the guide shell 103 through the notch 10201. The second guide surface 10301 is located on the inner side of the guide shell 103 and forms a 2° angle difference with the first guide surface 10202 of the cutter 102. When the slurry enters the guide shell through the notch 10201... After step 103, the curved surface will receive the downward pressure flow field of the first guide surface 10202. Through the gradual curvature guidance (the curvature of the curved surface increases smoothly from the inlet to the outlet), the slurry flow velocity will be increased from 0.3-0.5 m / s to 0.6-0.8 m / s, forming an accelerated downward pressure flow. At the same time, the second guide surface 10301 is precisely matched with the 30° downward tilt direction of the outlet of the guide shell 103, ensuring that the slurry flows into the lower circulation flow along the tangential downward trajectory when discharged (instead of vertically impacting the bottom slurry), avoiding backflow and air entrapment caused by the deviation of the outlet direction, thereby increasing the slurry conveying efficiency in the guide shell 103 by 40% and eliminating stagnation and accumulation.

[0050] The third guide surface 10302 is set on the outer liquid-facing surface of the guide shell 103, forming an inner and outer dual-control flow field with the second guide surface 10301. When the cutter 102 drives the guide shell 103 to rotate, the outer third guide surface 10302 will directly act on the surface slurry. By tilting the liquid-facing angle (at 25-30° with the rotation plane of the cutter 102), the slurry that is trying to roll up to the liquid surface is pushed back into the constrained flow field, cutting off the air entrapment path generated by the bubbles from the source.

[0051] As a further improvement to the present invention, such as Figure 9 and Figure 10 As shown, the guide shell 103 also includes a guide groove 10303, which is located inside the third guide surface 10302. The guide groove 10303 further guides the vortex downward to converge, reducing the amount of air entrainment caused by local turbulence.

[0052] As a further improvement to the present invention, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the cutter 102 and guide shell 103 connected to the first connecting ring 101 and the cutter 102 and guide shell 103 connected to the second connecting ring 104 are arranged in opposite directions. The cutter 102 and guide shell 103 connected to the first connecting ring 101 are both inclined downwards, and the inclination angle of the cutter 102 connected to the first connecting ring 101 is 20-25°, and the inclination angle of the guide shell 103 connected to the first connecting ring 101 is 25-30°. When the cutter 102 connected to the first connecting ring 101 rotates downwards, it will form a downward pressure flow field: forcibly pressing the surface slurry (the area near the liquid surface) to the bottom of the cavity. This design avoids the problem of traditional cutting blades throwing the slurry outwards and impacting the liquid surface, cutting off the path of air being drawn into the slurry from the source; the slurry flows smoothly downwards along the inclined surface of the cutter 102.

[0053] After being initially pressed down by the cutter 102, the slurry enters the arc-shaped channel of the guide shell 103 connected to the first connecting ring 101, and is guided to the bottom in an enclosed manner at an inclination angle of 25-30°, so as to prevent the slurry from spreading to the surroundings and forming eddies during the flow.

[0054] The arc-shaped inner wall of the guide shell 103 (the second guide surface 10301 and the third guide surface 10302) makes the slurry flow more uniform, without local velocity abrupt changes, and completely eliminates bubbles generated by turbulence.

[0055] The cutter 102 and guide shell 103 connected to the second connecting ring 104 are both inclined upwards, and the inclination angle of the cutter 102 connected to the second connecting ring 104 is 20-25°, and the inclination angle of the guide shell 103 connected to the second connecting ring 104 is 25-30°.

[0056] When the cutter 102, which is connected to the second connecting ring 104, tilts and rotates upward, it will form a spiral upward flow field: pushing the slurry at the bottom upward and forming an internal circulation flow field with the slurry pressed down in the lower layer;

[0057] This circulation ensures continuous mixing of the upper and lower layers of slurry in the cavity, preventing stagnant zones from forming at the bottom (static areas are prone to bubble formation due to localized fermentation or material accumulation).

[0058] After being pushed upward by the cutter 102, the slurry enters the arc-shaped channel of the guide shell 103 connected to the second connecting ring 104, and is guided to the middle layer area at an angle of 25-30° to avoid the slurry directly impacting the liquid surface (impact can easily cause air entrapment).

[0059] The curved surface design of the guide shell 103 (the second guide surface 10301 and the third guide surface 10302) allows the upward-pushed slurry to spread evenly and smoothly merge with the downward-pressed slurry in the upper layer, without bubbles generated by turbulent collisions.

[0060] As a further improvement to the present invention, such as Figure 3 , Figure 5 , Figure 11 , Figure 12 and Figure 13 As shown, the defoaming mechanism 2 includes a third connecting ring 201 sleeved on the outside of the connecting shaft 13. The surfaces of the first connecting ring 101, the second connecting ring 104, and the third connecting ring 201 are provided with threaded holes, and a set screw is spirally connected to the inner side of each threaded hole, so that the end face of the set screw abuts against the connecting shaft 13. After the first connecting ring 101, the second connecting ring 104, and the third connecting ring 201 are adjusted to a suitable height, the friction between the set screw and the connecting shaft 13 achieves the limiting and fixing of the first connecting ring 101, the second connecting ring 104, and the third connecting ring 201 and the connecting shaft 13. Both ends of the third connecting ring 201 are fixedly connected to a capturing shell 202. The capturing shell 202 has a flared opening facing the direction of rotation of the connecting shaft 13. Simultaneously, the third connecting ring 201 can adjust the position of the capturing shell 202 according to the height of the sample liquid level, so that the capturing shell 202 is above the sample liquid level, thereby facilitating the capturing shell 202 to capture foam above the sample liquid level. A guide shaft 205 is slidably connected to the inner side of the capture shell 202. A shaking block 203 is fixedly connected to the outer side of the guide shaft 205. Cutting blocks 204 are fixedly connected to both ends of the shaking block 203 and the inner wall of the capture shell 202. A baffle 211 is fixedly connected to one end of one of the guide shafts 205. A spring 210 is provided on the outer side of the guide shaft 205, and both ends of the spring 210 are fixedly connected to the capture shell 202 and the baffle 211 respectively. The spring 210 provides a tension to the baffle 211. The force causes the baffle 211 to push the shaking block 203 through the guide shaft 205, which facilitates the shaking block 203 to shake back and forth inside the capture shell 202. When the foam enters the inside of the capture shell 202, the shaking block 203 will also carry the corresponding cutting block 204 to cooperate with the cutting block 204 on the inner wall of the capture shell 202 to puncture the foam, reduce the foam above the sample liquid surface, thereby reducing the foam content in the sample liquid, and further reducing the volume error and sampling accuracy error caused by the foam.

[0061] As a further improvement to the present invention, such as Figure 5 , Figure 11 , Figure 12 and Figure 13As shown, the defoaming mechanism 2 also includes a fixing ring 214 fixedly connected to the upper cylinder 10. The bottom end of the fixing ring 214 is detachably connected to a support ring 212 by bolts, facilitating the disassembly and installation of the support ring 212 and the fixing ring 214. A guide ring 213 is fixedly connected to the top end of the support ring 212. A guide roller 208 is provided between the guide ring 213 and the support ring 212. A connecting frame 207 is rotatably connected to the outer side of the guide roller 208. The guide ring 213 has protrusions and concave surfaces around its perimeter, and the protrusions and concave surfaces are arranged alternately and continuously, so that the guide roller 208 moves along the perimeter of the guide ring 213. When rotating, it can reciprocate and move horizontally periodically; the other end of the connecting frame 207 is fixedly connected to the outer shell 206, the inner side of the outer shell 206 is slidably connected to the inner rod 215, and the inner rod 215 is fixedly connected to the shaking block 203; the inner side of one end of the outer shell 206 is screwed with the first locking screw 209, and the first locking screw 209 is in contact with the inner rod 215; when it is necessary to adjust the vertical position of the capture shell 202, the inner rod 215 and the outer shell 206 can be adjusted accordingly, and the first locking screw 209 can realize the limiting fixation between the inner rod 215 and the outer shell 206;

[0062] When the connecting shaft 13 rotates the capture shell 202 via the third connecting ring 201, the capture shell 202 also rotates the shaking block 203 around the vertical center line of the connecting shaft 13 via the guide shaft 205. The shaking block 203 rotates the guide roller 208 around the guide ring 213 via the inner rod 215, the outer shell 206 and the connecting frame 207. With the cooperation of the protrusions and concave surfaces around the guide ring 213, the guide roller 208 rotates the shaking block 203 periodically and rapidly back and forth inside the outer shell 206 via the connecting frame 207, the outer shell 206 and the inner rod 215.
