Description

Technical Field

[0001] This invention relates to the field of fruit peeling devices, and particularly to a roller-type fruit peeling device and its shell-meat separation system. Background Technology

[0002] Lychee fruit is delicious and nutritious, but its peel easily loses water and discolors after harvesting, thus losing its nutritional value. Therefore, the deep processing of lychee is imperative. Peeling is a crucial step in this process. Traditional manual peeling suffers from low efficiency, high cost, and severe damage to the fruit flesh. Existing mechanical peeling technologies such as squeezing, impact, and grasping peeling also have drawbacks, including high fruit flesh breakage rates, poor adaptability, and high costs. Therefore, roller-type mechanical peeling devices are gradually becoming the mainstream choice.

[0003] An existing patent (publication number: CN107242585A) discloses an automatic lychee pitting and peeling machine, including a housing; it also includes a feeding mechanism disposed at the upper end of the housing for loosening lychees, a pitting mechanism disposed inside the housing and opposite to the feeding mechanism for removing lychee pits, a peeling mechanism disposed inside the housing and connected to the pitting mechanism for removing lychee shells, and a discharge port disposed on one side of the housing and connected to the peeling mechanism. The housing is also provided with a driving device for driving the feeding mechanism, the pitting mechanism and the peeling mechanism. The driving device is provided with a first driving mechanism for driving the pitting mechanism and a second driving mechanism for driving the feeding mechanism and the peeling mechanism.

[0004] Although this application can effectively ensure the integrity of the fruit pulp, improve production efficiency, and reduce labor intensity, it relies solely on the direct squeezing of the first and second pressure rollers during peeling, which increases the risk of fruit pulp damage. It also causes some fruits to be unable to be separated due to small cracks, requiring manual assistance for peeling, thus reducing peeling efficiency. At the same time, the insufficient friction between the smooth roller surface and the fruit shell causes the lychees to easily slip in place after entering the rollers, making it difficult to transport them stably forward. This not only easily leads to the problem of alternating roller idling and fruit accumulation, but also causes the fruit to be subjected to continuous static pressure, which aggravates fruit pulp damage. Summary of the Invention

[0005] The purpose of this invention is to provide a roller-type fruit peeling device and its shell-meat separation system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roller-type fruit peeling device, comprising a washing component and an installation box installed on one side of the washing component. The installation box is provided with a screening component and a peeling component. The peeling component is located below the screening component. The screening component is used to sort fruits according to their particle size. The feed end of the screening component is connected to the discharge end of the washing component.

[0007] The installation box has a processing chamber inside. The peeling assembly includes a first extrusion roller and a second extrusion roller rotatably connected inside the processing chamber. The first extrusion roller and the second extrusion roller are arranged in a V-shape. Both the first extrusion roller and the second extrusion roller are fixed with bevel gears. The first extrusion roller and the second extrusion roller rotate synchronously in opposite directions through the bevel gears. Both the first extrusion roller and the second extrusion roller are provided with protrusions, which are evenly arranged in a spiral shape.

[0008] Preferably, the surface of the first extrusion roller is provided with a guide groove, and the inside of the first extrusion roller is provided with a negative pressure chamber and an exhaust chamber. The negative pressure chamber and the exhaust chamber are both connected to the guide groove. The inner wall of the negative pressure chamber is provided with a connecting hole, and the inner wall of the connecting hole is rotatably connected to a one-way baffle by a torsion spring. The negative pressure chamber and the exhaust chamber are connected or closed by the rotation of the one-way baffle.

[0009] Preferably, a discharge plate is fixed to the side of the mounting box, and an air pump is installed inside the discharge plate. The output end of the air pump is rotatably inserted into the negative pressure chamber. The air pump is used to keep the negative pressure chamber in a negative pressure state during the shelling operation. One end of the first extrusion roller passes through the mounting box, and one end of the first extrusion roller is connected to an external drive motor.

[0010] Preferably, a limiting plate is fixed to the side of both the first and second extrusion rollers. The lower surface of the limiting plate has an arc-shaped surface. A connecting pipe passes through the side of the limiting plate. The other end of the connecting pipe is connected to the water pump of the cleaning component. A control valve is also installed on the surface of the connecting pipe. A drainage hole is opened inside the limiting plate. The arc-shaped surface of the limiting plate is spaced 2-5mm from the surface of the first extrusion roller.

[0011] Preferably, the screening assembly includes a rotary motor installed on the side of the housing, a screening barrel fixed to the output end of the rotary motor, a screening chamber opened inside the housing, a fixing plate fixed to the inner wall of the screening chamber, a slider fixed to the side of the screening barrel, a groove corresponding to the slider opened on the side of the fixing plate, the slider moving inside the groove, and the screening barrel rotating inside the screening chamber by the rotary motor and the slider.

[0012] Preferably, a feed pipe is fixed on the upper surface of the fixed plate, a guide plate is fixed on the side of the fixed plate, the other side of the guide plate passes through the inside of the screening barrel, two sets of screening holes of different diameters are opened on the surface of the screening barrel, a spiral blade is fixed on the inner wall of the screening barrel, a discharge port is opened on the inner wall of the screening chamber, the screening chamber is connected to the processing chamber through the discharge port, and the position of the discharge port corresponds to the shelling component.

[0013] Preferably, the processing chamber is further provided with a collection trough, which is located below the shelling assembly. The front of the mounting box has a discharge port, and the position of the discharge plate corresponds to the discharge port.

[0014] The present invention also provides a shell-meat separation system, comprising the following steps: S1. The fruit is fed into the washing unit for washing to remove surface impurities, and then the clean fruit is fed into the screening unit through the feed pipe. S2. The screening barrel is driven to rotate by a rotary motor, so that the fruit is pushed along the axis by the spiral blades and graded according to particle size using screening holes of different diameters. The graded fruit falls into the peeling component in the corresponding area through the feeding port. S3. Start the external drive motor to make the first and second extrusion rollers rotate synchronously in opposite directions through bevel gear transmission. The spiral protrusions on the roller surface apply extrusion and friction to the fruit shell, causing the fruit shell to crack along the natural texture. At the same time, the air pump generates negative pressure in the negative pressure chamber, and the fruit shell is adsorbed through the guide groove to enhance the peeling effect. The separated fruit shell falls into the collection tank, and the fruit pulp is discharged from the discharge port through the discharge plate to complete the separation. S4. After separation, the water pump delivers water to the inside of the limiting plate through the connecting pipe. The water is sprayed out through the drain hole to clean the surface of the first and second extrusion rollers. At the same time, the air pump introduces air into the negative pressure chamber. The one-way baffle rotates under the action of the airflow, connecting the negative pressure chamber with the exhaust chamber, so that the airflow is sprayed out through the guide groove to clean the guide groove and the roller surface.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention enables the peeling of fruit and separation of the flesh from the shell by setting a peeling component. The first and second squeezing rollers are arranged in a V-shape and have spiral protrusions on their surfaces. They rotate synchronously in opposite directions through bevel gears, which not only increases the squeezing and friction on the fruit shell, causing the shell to crack along its natural texture, but also effectively reduces the risk of damage to the flesh compared to the traditional direct squeezing method. At the same time, it improves the success rate of peeling and reduces the need for manual peeling. Moreover, the spiral protrusions can guide the fruit to be transported forward stably, avoiding the fruit from slipping in place and the rollers from spinning idly. This reduces the damage to the flesh caused by static squeezing and improves peeling efficiency and flesh integrity.

[0016] 2. The present invention utilizes a negative pressure chamber and guide groove inside the first extrusion roller. During the peeling process, the negative pressure chamber is generated by an air pump to adsorb the fruit shells and enhance the peeling effect, thereby improving the peeling success rate. At the same time, after separation, the surfaces of the first and second extrusion rollers can be cleaned by a water pump and an air pump, respectively, ensuring the cleanliness of the first and second extrusion rollers and the smooth progress of subsequent peeling operations, thus extending the service life of the device.

[0017] 3. This invention uses a screening component to grade fruits according to their particle size, allowing fruits of different sizes to fall into the corresponding peeling components. This effectively avoids uneven peeling caused by differences in fruit size, improves peeling accuracy and adaptability, reduces equipment jamming or incomplete peeling caused by mismatched fruit sizes, and enhances overall production efficiency.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1 This invention provides, for example Figures 1 to 7 The roller-type fruit peeling device shown includes a washing component 1 and an installation box 2 installed on one side of the washing component 1. The installation box 2 is equipped with a screening component 3 and a peeling component 4. The peeling component 4 is located below the screening component 3. The screening component 3 is used to sort the fruit according to its particle size. The feed end of the screening component 3 is connected to the discharge end of the washing component 1.

[0022] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The installation box 2 has a processing chamber 203 inside. The peeling assembly 4 includes a first squeezing roller 401 and a second squeezing roller 402 rotatably connected inside the processing chamber 203. The first squeezing roller 401 and the second squeezing roller 402 are arranged in a V-shape. Both the first squeezing roller 401 and the second squeezing roller 402 have bevel gears 408 fixed on their surfaces. The first squeezing roller 401 and the second squeezing roller 402 rotate synchronously in opposite directions through the bevel gears 408. Both the first squeezing roller 401 and the second squeezing roller 402 have protrusions 403 on their surfaces, which are evenly arranged in a spiral shape. The V-shaped arrangement of the first squeezing roller 401 and the second squeezing roller 402 allows the fruit to naturally converge to the middle area of ​​the two rollers, preventing the fruit from spreading outwards during transportation. Lateral offset ensures that the fruit can be squeezed simultaneously by the first squeezing roller 401 and the second squeezing roller 402. The bevel gear 408 enables the first squeezing roller 401 and the second squeezing roller 402 to rotate synchronously in opposite directions, ensuring that a uniform and symmetrical squeezing force is applied to the fruit, preventing the fruit from being squeezed off the roller body or damaged due to uneven force due to unilateral force. At the same time, the spirally evenly distributed protrusions 403 on the surface of the first squeezing roller 401 and the second squeezing roller 402 not only enhance the friction with the fruit shell and drive the fruit to be transported forward stably in the spiral direction, but also apply force along the natural texture of the fruit shell, causing the fruit shell to crack along the natural texture. Meanwhile, the dispersed protrusions 403 can also avoid excessive concentration of squeezing force and reduce squeezing damage to the fruit pulp.

[0023] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7The first extrusion roller 401 has a guide groove 404 on its surface and a negative pressure chamber 405 and an exhaust chamber 406 inside it. Both the negative pressure chamber 405 and the exhaust chamber 406 are connected to the guide groove 404. The inner wall of the negative pressure chamber 405 has a connecting hole 409. The inner wall of the connecting hole 409 is rotatably connected to a one-way baffle 410 by a torsion spring. The negative pressure chamber 405 and the exhaust chamber 406 are connected or closed by the rotation of the one-way baffle 410. The guide groove 404 is connected to the negative pressure chamber 405 and the exhaust chamber 406. The connection between 06 and the negative pressure chamber 405 allows the guide groove 404 to form a stable adsorption force on the cracked fruit shells during the peeling process, making the fruit shells adhere more closely to the surface of the extrusion roller, which facilitates subsequent separation operations. The one-way baffle 410 can flexibly switch the connection state between the negative pressure chamber 405 and the exhaust chamber 406 by rotating itself. During peeling, the negative pressure of the negative pressure chamber 405 is kept stable to maintain the adsorption effect. During cleaning, it can connect to the exhaust chamber 406, allowing airflow to be sprayed out through the guide groove 404 to clean the roller surface.

[0024] Please see Figure 2 , Figure 3 and Figure 4 A discharge plate 7 is fixed to the side of the mounting box 2. An air pump 407 is installed inside the discharge plate 7. The output end of the air pump 407 is rotatably inserted into the negative pressure chamber 405. The air pump 407 is used to keep the negative pressure chamber 405 in a negative pressure state during the peeling operation. One end of the first extrusion roller 401 passes through the mounting box 2 and is connected to an external drive motor. The air pump 407 installed in the discharge plate 7 can continuously provide a stable negative pressure environment for the negative pressure chamber 405, ensuring that the adsorption force of the guide groove 404 on the fruit shell is always uniform and reliable, and avoiding incomplete separation of the fruit shell and pulp due to insufficient negative pressure. Limiting plates 602 are fixed to the sides of the first extrusion roller 401 and the second extrusion roller 402. The lower surface of the limiting plate 602 has an arc-shaped surface. A connecting pipe 601 passes through the side of the limiting plate 602. The other end of the connecting pipe 601 is connected to the cleaning... The water pump of component 6 is connected, and a control valve is installed on the surface of the connecting pipe 601. The limiting plate 602 has a drain hole 603 inside. The arc-shaped surface of the limiting plate 602 is 2-5mm away from the surface of the first extrusion roller 401. The arc-shaped surface of the limiting plate 602 and the surface of the extrusion roller maintain an appropriate distance, which not only limits the fruit during transportation and prevents the fruit from falling from both sides of the roller, but also avoids hard contact with the roller surface and avoids damage to the roller surface and the limiting plate 602 itself. The connecting pipe 601 is connected to the water pump of cleaning component 6. With the help of the drain hole 603 in the limiting plate 602, cleaning liquid can be sprayed onto the roller surface to wash away the residual fruit shell debris and juice on the roller surface, keep the roller surface clean and maintain a stable peeling effect. At the same time, the control valve can control the opening and closing of the connecting pipe 601 according to the working status to ensure that the peeling work is not disturbed.

[0025] Please see Figure 2 and Figure 4The screening assembly 3 includes a rotary motor 301 mounted on the side of the housing. A screening barrel 302 is fixed to the output end of the rotary motor 301. A screening chamber 201 is opened inside the housing 2. A fixing plate 303 is fixed to the inner wall of the screening chamber 201. A slider 304 is fixed to the side of the screening barrel 302. A groove corresponding to the slider 304 is opened on the side of the fixing plate 303. The slider 304 moves inside the groove. The screening barrel 302 rotates inside the screening chamber 201 through the rotary motor 301 and the slider 304. The slider 304 and the groove not only support the screening barrel 302 and ensure the stability of the screening barrel 302 when rotating, avoiding shaking and uneven screening, but also reduce the frictional resistance when rotating, reduce the noise and wear of the parts during the operation of the device. With the help of the rotary motor 301, the screening barrel 302 can rotate continuously to achieve rolling screening of the fruit. Furthermore, the rotation of the screening barrel 302 inside the screening chamber 201 allows the fruit to be screened in a relatively enclosed space, preventing the fruit from falling.

[0026] Additionally, please see Figure 1 , Figure 2 and Figure 4 A feed pipe 305 is fixed to the upper surface of the fixed plate 303, and a guide plate 306 is fixed to the side of the fixed plate 303. The other side of the guide plate 306 passes through the inside of the screening barrel 302. Two sets of screening holes 307 of different diameters are opened on the surface of the screening barrel 302. Spiral blades 308 are fixed to the inner wall of the screening barrel 302. A discharge port 202 is opened on the inner wall of the screening chamber 201. The screening chamber 201 is connected to the processing chamber 203 through the discharge port 202. The position of the discharge port 202 corresponds to the peeling component 4. The cooperation between the feed pipe 305 and the guide plate 306 can filter the cleaned material. The fruit is smoothly fed into the screening bin 302, avoiding accumulation or bumping during feeding and reducing fruit damage. The two sets of screening holes 307 of different sizes on the surface of the screening bin 302 can classify the fruit according to its particle size, allowing fruits of similar size to enter the peeling component 4 below. This ensures that the squeezing pressure during peeling is suitable for the fruit, avoiding incomplete peeling or damage to the pulp due to excessive differences in fruit size. At the same time, the spiral blades 308 on the inner wall of the screening bin 302 can drive the fruit to move axially when the bin rotates, so that the fruit passes evenly through the screening holes 307, improving screening efficiency and uniformity.

[0027] Please see Figure 2 and Figure 6The processing chamber 203 is also equipped with a collection trough 5, which is located below the shelling component 4. The front of the installation box 2 has a discharge port, and the position of the discharge plate 7 corresponds to the discharge port. The collection trough 5 located below the shelling component 4 can promptly collect the fruit shells separated during the shelling process, preventing the fruit shells from accumulating in the processing chamber 203 and interfering with the shelling operation. It also facilitates the subsequent centralized cleaning of the fruit shells. The discharge plate 7 corresponds to the discharge port, so that the peeled fruit pulp can be smoothly discharged from the device, preventing the fruit pulp from falling or accumulating during discharge and ensuring that the fruit pulp is discharged intact.

[0028] It should be noted that a hydrophobic membrane is embedded inside the guide groove 404. This membrane prevents fruit juice from seeping into the negative pressure chamber 405 and the exhaust chamber 406, thus avoiding contamination and blockage of the chambers and ensuring long-term smooth airflow. Preferably, the outer layer of the first extrusion roller 401 and the second extrusion roller 402 is a Shore 45A soft layer, and the inner layer is a Shore 60A support layer. The soft layer can closely conform to the texture of the fruit shell surface. Combined with the spiral protrusions 403 of the extrusion roller, it enhances the friction with the fruit shell, preventing slippage and stagnation during fruit transport. It also guides the shear force along the natural weak line of the fruit shell (the stem-top line of the lychee), improving the accuracy of directional cracking. The high-hardness support layer provides sufficient rigidity for the extrusion roller, preventing over-extrusion. During the process, the rollers deform due to the force, allowing the first squeezing roller 401 and the second squeezing roller 402 to maintain their preset gap. This ensures that the squeezing force on the fruit is uniform and consistent, preventing some fruits from being incompletely peeled or over-squeezed due to roller deformation. The inclination of the first squeezing roller 401 and the second squeezing roller 402 is 3°-5°. When the first squeezing roller 401 and the second squeezing roller 402 rotate synchronously in opposite directions, there is a small angle in the linear velocity direction at each point of contact with the fruit. This means that the friction force of the first squeezing roller 401 and the second squeezing roller 402 on the surface of the lychee is not pure squeezing, but rather forms a "misaligned" shearing force to tear the peel, thus tearing it along the naturally occurring weak lines of the lychee.

[0029] In addition, the flexible bonding of the outer layer of the first extrusion roller 401 and the outer layer of the second extrusion roller 402 enhances the adsorption effect of the guide groove 404. Specifically, when the soft layer deforms, the guide groove 404 contacts the fruit shell more tightly, the negative pressure adsorption force is more stable, and the fruit shell will not fall off during rotation, thus achieving peeling in conjunction with shearing force.

[0030] The working principle of the above embodiments is as follows: First, the device is placed in the designated location and connected to an external power source and control equipment. The control equipment specifically includes known conventional equipment such as a controller and computer with control functions. Then, the staff pours the fruit into the washing assembly 1. The washing assembly 1 uses its internal washing mechanism to perform preliminary washing of the fruit, removing surface dirt, impurities, etc. The washed fruit enters the feed pipe 305 of the screening assembly 3 through the discharge end of the washing assembly 1. The fruit smoothly enters the screening barrel 302 along the feed pipe 305 and the guide plate 306. At this time, the rotary motor 301 is started, which drives the screening barrel 302 to rotate in the screening chamber 201. The spiral blades 308 on the inner wall of the screening barrel 302 drive the fruit to move axially, so that the fruit passes evenly through two sets of screening holes 307 of different diameters on the surface of the screening barrel 302. The fruit is graded according to its particle size, and the water bucket with the same particle size enters the corresponding peeling assembly 4 in the processing chamber 203 through the screening holes 307 and the lower discharge port 202.

[0031] The fruit entering the peeling assembly 4 converges in the middle area where the first squeezing roller 401 and the second squeezing roller 402 are arranged in a V-shape. An external drive motor drives the first squeezing roller 401 to rotate, and the first squeezing roller 401 drives the second squeezing roller 402 to rotate synchronously in the opposite direction through a bevel gear 408. The spirally evenly distributed protrusions 403 on the surfaces of the first squeezing roller 401 and the second squeezing roller 402 enhance the friction with the fruit shell, causing the fruit to be stably conveyed forward in the spiral direction. At the same time, force is applied along the natural texture of the fruit shell, causing the fruit shell to crack along the natural texture. The dispersed protrusions 403 prevent excessive concentration of squeezing force and reduce squeezing damage to the fruit pulp. During the peeling process, the fruit is installed in the discharge plate 7. The air pump 407 operates, putting the negative pressure chamber 405 inside the first extrusion roller 401 into a negative pressure state. This causes the guide groove 404, which is connected to the negative pressure chamber 405, to form a stable adsorption force on the cracked fruit shell, making the fruit shell adhere more closely to the surface of the extrusion roller. At the same time, the one-way baffle 410 can block the connection between the exhaust chamber 406 and the negative pressure chamber 405, so that the negative pressure chamber 405 can maintain the stability of the negative pressure during peeling to maintain the adsorption effect. After peeling, the fruit shell falls into the collection trough 5, and the fruit pulp is discharged from the outlet along the discharge plate 7. During the operation of the device, the limiting plate 602 plays a limiting role in the conveying of fruit, preventing the fruit from falling from both sides of the roller body, and avoiding hard contact with the roller surface.

[0032] During the peeling process, the outer soft layers of the first and second squeezing rollers 401 and 402 closely adhere to the surface texture of the fruit shell, enhancing the friction with the fruit shell and guiding the shearing force along the natural weak lines of the fruit shell, thus improving the accuracy of directional cracking. The inner support layer provides sufficient rigidity for the squeezing rollers to prevent deformation of the rollers during the squeezing process. At the same time, the inclined setting of the first and second squeezing rollers 401 and 402 creates a "misaligned" shearing force at the point of contact with the fruit, tearing it along the naturally occurring weak lines of the lychee. The flexible adhesion of the outer layers of the first and second squeezing rollers 401 and 402 enhances the adsorption effect of the guide groove 404, ensuring that the fruit shell will not fall off during rotation, thus achieving peeling in conjunction with the shearing force.

[0033] When the roller surface needs to be cleaned, the water pump of the cleaning component 6 delivers cleaning liquid to the limiting plate 602 through the connecting pipe 601. The cleaning liquid is sprayed onto the roller surface through the drain hole 603 to wash away the residual fruit shell fragments and juice on the roller surface. The control valve controls the opening and closing of the connecting pipe 601 according to the working status to ensure that it does not interfere with the peeling work. At the same time, the air pump 407 introduces air into the negative pressure chamber 405. The one-way baffle 410 rotates under the action of the airflow, so that the negative pressure chamber 405 is connected to the exhaust chamber 406, thereby allowing the airflow to be sprayed out through the guide groove 404 to clean the roller surface. During the cleaning process, the hydrophobic membrane embedded in the guide groove 404 prevents the fruit juice from seeping into the negative pressure chamber 405 and the exhaust chamber 406, avoiding contamination and blockage of the chamber by juice.

[0034] Example 2 The present invention also provides a shell-meat separation system, comprising the following steps: S1. The fruit is sent into the washing assembly 1 for washing to remove surface impurities. Then the clean fruit is introduced into the screening assembly 3 through the feed pipe 305. S2. The rotary motor 301 drives the screening barrel 302 to rotate, so that the fruit is pushed along the axis by the spiral blade 308, and is graded according to particle size using screening holes 307 of different diameters. The graded fruit falls into the peeling component 4 in the corresponding area through the feeding port 202. S3. Start the external drive motor to make the first extrusion roller 401 and the second extrusion roller 402 rotate synchronously in opposite directions through the bevel gear 408. The spiral protrusions 403 on the roller surface apply extrusion and friction to the fruit shell, causing the fruit shell to crack along the natural texture. At the same time, the air pump 407 generates negative pressure in the negative pressure chamber 405, and the fruit shell is adsorbed through the guide groove 404 to enhance the peeling effect. The separated fruit shell falls into the collection tank 5, and the fruit pulp is discharged from the discharge port through the discharge plate 7, completing the separation. S4. After separation, the water pump delivers water to the inside of the limiting plate 602 through the connecting pipe 601. The water is sprayed out through the drain hole 603 to clean the surface of the first extrusion roller 401 and the second extrusion roller 402. At the same time, the air pump 407 introduces air into the negative pressure chamber 405. The one-way baffle 410 rotates under the action of the airflow, so that the negative pressure chamber 405 is connected to the exhaust chamber 406, thereby allowing the airflow to be sprayed out through the guide groove 404 to clean the guide groove 404 and the roller surface.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
