Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable processing technology, and in particular relates to a wet threshing machine for fruits and vegetables. Background Technology

[0002] In the fruit and vegetable processing step of breaking the sac, two common methods are used: one is to use chemical methods to remove the skin of the sac segments first, and then use a machine to break the segments apart to obtain juice vesicles; the other is to use a high-speed rotating and tumbling device to subject the sac segments with juice vesicles to continuous impacts until the skin ruptures and the juice vesicles fall out of the device. During this process, the sac segments and scattered juice vesicles tumble and tumble rapidly within the device, experiencing friction and impacts from all directions, which easily leads to juice vesicle damage. In traditional dry threshers, the impact stress between the sac segments and the inner wall of the device can reach 0.6-0.8 MPa, far exceeding the tolerance limit of fruit and vegetable juice vesicles, resulting in a high juice vesicle damage rate and increased material loss. Therefore, there is a need for equipment that can reduce juice vesicle loss during the sac breaking process. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a wet threshing machine for fruits and vegetables.

[0004] This utility model is achieved through the following technical solution.

[0005] This utility model provides a wet threshing machine for fruits and vegetables, including a desiccant chamber, a sedimentation chamber, a discharge trough, a conveyor, and a water circulation mechanism. The desiccant chamber is connected to the sedimentation chamber, one end of the discharge trough is connected to the sedimentation chamber, and the other end is connected to the conveyor. A water collection tank on the conveyor is connected to the inlet of the water circulation mechanism, and the outlet of the water circulation mechanism is connected to both the desiccant chamber and the sedimentation chamber.

[0006] Preferably, a partition is provided between the capsule breaking chamber and the sedimentation chamber, and an opening is provided on the partition. The capsule breaking chamber and the sedimentation chamber are connected through the opening, and mesh slots for installing mesh are provided on both sides of the opening.

[0007] Preferably, the inner wall of the cyst-breaking chamber is provided with auxiliary cyst-breaking rods, the top of the cyst-breaking chamber is provided with a crossbeam and a slag discharge port, the bottom of the cyst-breaking chamber is connected to a water circulation mechanism through a first water supply pipe, a motor is installed on the crossbeam, the output shaft of the motor is connected to a connecting rod, the connecting rod extends into the cyst-breaking chamber, and several main cyst-breaking rods are provided on the connecting rod.

[0008] Preferably, the adjacent main rupture rods are horizontally installed at staggered angles, and the auxiliary rupture rod is located between two adjacent main rupture rods on the horizontal plane.

[0009] Preferably, a waste discharge valve and a second water supply pipe are provided at the bottom of the sedimentation tank, and the sedimentation tank is connected to a water circulation mechanism through the second water supply pipe.

[0010] Preferably, the sedimentation tank is provided with a discharge port, and mesh slots for installing the discharge port mesh are provided on both sides of the discharge port. The water outlet axis of the second water supply pipe is inclined towards the discharge port.

[0011] Preferably, a settling pit and a mesh screen are provided on the discharge trough, and a slag discharge valve is provided at the bottom of the settling pit.

[0012] Preferably, the conveyor is a conveyor using a mesh conveyor belt, and the water collection tank is located below the mesh conveyor belt.

[0013] Preferably, the water circulation mechanism includes a circulation pump and a connecting pipe. The inlet of the circulation pump is connected to the outlet of the water collection tank through the connecting pipe, and the outlet of the circulation pump is connected to the capsule breaking chamber and the sedimentation chamber through the connecting pipe.

[0014] The beneficial effects of this utility model are as follows: This invention uses a blasting chamber to break up the sacs and juice cells of fruits and vegetables. After passing through a sedimentation chamber and a discharge trough for multiple filtrations to remove impurities, the juice cells flow with water into a conveyor belt, where they separate from the water. Finally, the juice cells are transferred to the next process via a mesh conveyor belt. The components of this invention can be made of stainless steel, and the smooth surface reduces damage caused by the movement of the juice cells. The buoyancy of water protects the juice cells, reducing collisions and lowering the breakage rate. The sac segments float or are suspended in the water due to buoyancy. As the equipment operates rapidly, when the segments are impacted by the main blasting bar, the reaction force causes them to bounce off. However, the water resistance prevents the rebound speed and distance of the segments, reducing ineffective collisions with the equipment and lowering the breakage rate. During the blasting process in the threshing machine, water is continuously supplied to the blasting chamber, and the scattered juice cells flow out of the equipment with the water flow, thus achieving automatic threshing. A circulation component enables water circulation, reducing production costs. Attached Figure Description

Detailed Implementation

[0016] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0017] Example: like Figure 1 As shown, a wet threshing machine for fruits and vegetables includes a desiccant chamber 1, a sedimentation chamber 2, a discharge trough 11, a conveyor 14, and a water circulation mechanism. The desiccant chamber 1 is connected to the sedimentation chamber 2. One end of the discharge trough 11 is connected to the sedimentation chamber 2, and the other end is connected to the conveyor 14. A water collection tank 15 provided on the conveyor 14 is connected to the water inlet of the water circulation mechanism. The water outlet of the water circulation mechanism is connected to the desiccant chamber 1 and the sedimentation chamber 2 respectively.

[0018] A partition 18 is provided between the cell-breaking chamber 1 and the sedimentation chamber 2. The partition 18 has an opening with a size of 30cm * 100cm, through which the cell-breaking chamber 1 and the sedimentation chamber 2 are connected. Slots for installing a mesh screen 7 are provided on both sides of the opening to facilitate the replacement of the mesh screen 7. The mesh screen 7 has a mesh size of 2cm * 2cm and is used to filter large particles while allowing juice cells to pass through. During use, the cell-breaking chamber 1 and the sedimentation chamber 2 are filled with water. Juice cells can flow from the cell-breaking chamber 1 to the sedimentation chamber 2 with the water flow. Under the stirring action of the motor 20, the water flow agitation prevents juice cells from remaining on the mesh screen 7 for extended periods and causing blockage.

[0019] The inner wall of the capsule-breaking chamber 1 is equipped with several stainless steel auxiliary capsule-breaking rods 5 arranged from top to bottom. The auxiliary capsule-breaking rods 5 are perpendicular to the inner wall of the capsule-breaking chamber 1. The auxiliary capsule-breaking rods 5 passively impact the fruit and vegetable capsules, increasing resistance and improving capsule-breaking efficiency. The top of the capsule-breaking chamber 1 is equipped with a crossbeam 19 and a slag discharge port 3. The bottom of the capsule-breaking chamber 1 is connected to a water circulation mechanism through a first water supply pipe 6. Water is sprayed upward from the opening of the first water supply pipe 6, which can effectively promote the upward and downward circulation of materials in the capsule-breaking chamber 1. A motor 20 is installed on the crossbeam 19. The output shaft of the motor 20 is connected to a connecting rod 21. The connecting rod 21 extends into the capsule-breaking chamber 1 and is equipped with several main capsule-breaking rods 4. After the capsules are broken, some capsule skin and fibers are produced. These are relatively light and float on the water surface, and can be discharged from the capsule-breaking chamber 1 through the slag discharge port 3.

[0020] The main function of the capsule-breaking chamber 1 is to break down the skin of the fruit and vegetable segments after the outer skin has been removed, and to break the juice vesicles inside the segments into individual particles through agitation, thus achieving capsule breaking and granulation. The capsule-breaking chamber 1 has a capacity of 1 cubic meter and is equipped with a cylindrical inner wall with a diameter of 1 meter. The motor 20 rotates, driving the connecting rod 21 to rotate. The motor 20 rotates at a speed of 180 r / min to reduce the probability of juice vesicle breakage, which in turn drives the stainless steel main capsule-breaking rod 4 to rotate. During operation, the main capsule-breaking rod 4 continuously impacts the segments, achieving the effect of capsule breaking.

[0021] The adjacent main rupture rods 4 are horizontally installed and staggered at a 15-degree angle. The auxiliary rupture rod 5 is located on the horizontal plane between the two adjacent main rupture rods 4. The distance between the auxiliary rupture rod 5 and the main rupture rod 4 can be set to 1.5-2 cm as needed. The installation distance between the two main rupture rods 4 is 5 cm, and the main rupture rods 4 are installed all the way to the lower end of the connecting rod 21. In practical applications, this arrangement results in the highest uniformity of rupture fragmentation (uniformity coefficient 0.85), the shortest rupture time, and the auxiliary rupture rod 5 also minimizes the impact blind zone.

[0022] The sedimentation chamber 2 collects juice sacs, pericarps, seeds, and some fruit and vegetable fibers flowing from the sac-breaking chamber 1. A waste discharge valve 9 and a second water supply pipe 8 are installed at the bottom of the sedimentation chamber 2, which is connected to a water circulation mechanism via the second water supply pipe 8. The sedimentation chamber 2 is rinsed with running water to further separate the juice sacs. The heavier seeds sink to the bottom, while the pericarps and fibers float on the surface, leaving only the juice sacs in the middle. The waste discharge valve 9 is used to discharge seeds and other debris. The sedimentation chamber 2 is provided with a discharge port 10, the height of which is greater than the height of the conveyor 14. Slots for installing the discharge port mesh are provided on both sides of the discharge port 10, facilitating mesh replacement. The mesh size of the discharge port mesh is 2cm x 2cm, further filtering large particles. The outlet axis of the second water supply pipe 8 is inclined towards the discharge port 10. When juice cells and other materials in the cell-breaking chamber 1 flow into the sedimentation chamber 2, the water flow generated by the second water supply pipe 8 pushes these materials towards the discharge port 10. As the water flow force weakens, the materials begin to separate, with heavier materials sinking and lighter materials floating. The juice cells are located below the floating cell skin and fiber layer. The water flow velocity of the second water supply pipe 8 can be set to 0.5m / s to avoid damage to fruits and vegetables.

[0023] The discharge trough 11 is provided with a sedimentation pit 12 and a discharge trough mesh 13. The discharge trough mesh 13 is provided with multiple channels along the discharge trough 11 to further intercept fruit and vegetable fibers. The discharge trough mesh 13 is provided with a slot connection method for easy replacement. The sedimentation pit 12 is provided with a slag discharge valve 22 at the bottom. The fruit pits that flow out with the juice cells sink into the sedimentation pit 12 and are finally discharged through the slag discharge valve 22.

[0024] The conveyor 14 is the conveyor for the mesh conveyor belt 16. This conveyor is a structure that includes a motor and rollers and can drive the conveyor belt to move. It is existing technology and will not be described in detail here. The mesh conveyor belt 16 separates juice cells and water. The water collection tank 15 is located below the mesh conveyor belt 16 to facilitate the water flowing out of the discharge trough 11 to fall into the water collection tank 15.

[0025] The water circulation mechanism includes a circulation pump 17 and a connecting pipe 23. The inlet of the circulation pump 17 is connected to the outlet of the water collection tank 15 through the connecting pipe 23, and the outlet of the circulation pump 17 is connected to the first water supply pipe 6 of the capsule breaking chamber 1 and the second water supply pipe 8 of the sedimentation chamber 2 through the connecting pipe 23.

[0026] When using this invention, water is filled into the capsule breaking chamber 1 and the sedimentation chamber 2. After the water level reaches the height of the discharge port 10, the processed capsules are placed in. The capsules of fruits and vegetables are broken in the capsule breaking chamber 1 and the juice cells are dispersed. Then they enter the sedimentation chamber 2 for further filtration and sedimentation. Afterward, the juice cells enter the discharge trough 11 with the water flow. After being filtered multiple times in the discharge trough 11, they flow to the conveyor 14. The juice cells are separated from the water by the mesh conveyor belt 16 and finally sent to the next processing step.

[0027] Wet threshers use water as a medium. In practical use, the buffering effect of water can reduce impact stress to 0.2-0.25 MPa, which is lower than the cell wall's tolerance stress, fundamentally reducing damage. This equipment can control the fruit and vegetable juice cell breakage rate to below 8% and increase material separation efficiency to over 92%, resulting in excellent processing performance.
