DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Please see attached Figure 1 The present invention provides a method for cutting fresh potato curly fries, comprising:

[0048] (1) The potatoes are fed into the hydraulic cutter through the feeder, and the potatoes and water are pumped into the conveying pipeline using a special pump.

[0049] In this embodiment, step S1 is to convey potatoes to the conveying pipeline of the hydraulic cutter through the feeder, and to pump potatoes and water into the pipeline together with a special pump to achieve continuous conveying of potatoes.

[0050] Typically, a feeder is used to transport potatoes from the raw material storage area to the inlet of the hydraulic cutter. The feeder can be a belt conveyor or a vibrating conveyor, depending on the processing capacity requirements and the shape and size of the potatoes.

[0051] Specifically, after the conveyor belt delivers the potatoes to the feed port of the hydraulic cutter, the potatoes immediately enter the delivery pipe connected to the dedicated pump. Generally, the inner diameter of the delivery pipe needs to be designed according to the maximum short diameter of the potatoes. In a possible implementation, the inner diameter of the delivery pipe is set to 1.5 times the maximum short diameter of the potatoes.

[0052] The function of the dedicated pump is to extract water from the water storage tank and pump the potatoes and water into the delivery pipeline in a high-pressure form. Generally, the flow rate and pressure of the dedicated pump need to match the resistance in the delivery pipeline to maintain a stable delivery efficiency. In some embodiments, the dedicated pump can be a centrifugal pump or an axial flow pump.

[0053] (2) Use a guiding mechanism to orient potatoes

[0054] In this embodiment, step S2 uses a guiding mechanism to orient the potatoes so that their long axis direction is consistent with the direction of the water flow and is located at the center of the water flow, thereby providing accurate and stable raw material positioning for the subsequent cutting step.

[0055] Generally, the guide mechanism is set between the conveying pipe and the cutting device. Its main function is to adjust and constrain the posture of the potatoes so that the potatoes can enter the cutting device in a predetermined direction. The structural design of the guide mechanism must take into account the fluid mechanics characteristics and the shape characteristics of the material to avoid the potatoes from being offset or under-rotated during the orientation process.

[0056] Specifically, the guide mechanism consists of a tapered channel and a directional plate. The tapered channel is used to gradually reduce the inner diameter of the conveying pipe and guide the potatoes in a free state to the center. The directional plate adjusts the direction of its long axis to be parallel to the water flow direction through contact and friction with the potato surface.

[0057] In one possible implementation, the conical channel is designed with a tapered structure, and its contraction angle can be adjusted according to the average short diameter of the potato. For example, for potatoes with a short diameter of 4 to 6 cm, the contraction angle of the conical channel can be set to 15° to 20° to achieve smooth fluid contraction; while for potatoes with a short diameter of 6 to 8 cm, the contraction angle can be appropriately increased to 25° to 30° to speed up the orientation process.

[0058] The design of the directional plate usually adopts an inclined or curved structure, and the specific form can be optimized according to the shape characteristics of the potato. In a possible implementation, the directional plate is composed of a plurality of plates with an inclination angle of 10° to 15°, which are arranged around the channel outlet to adjust the direction of the potato through multi-point contact. As an improvement, strip-shaped protrusions or fine lines can be set on the surface of the directional plate to increase the friction between the potato and the plate to ensure a more precise directional effect.

[0059] (3) After being oriented, the potatoes enter the cutting device. Under the combined action of high-speed water flow and the rotating motion of the cutter, the potatoes are first cut into rolls of constant thickness, and then the rolls are further cut into rolls of constant width.

[0060] In this embodiment, step S3 is that the potatoes are oriented and then enter the cutting device, and the cutting operation is completed under the combined action of the high-speed water flow and the rotating motion of the cutter, specifically including first cutting the potatoes into curly sheets of constant thickness, and then further cutting the curly sheets into curly strips of constant width. The structure, cutting principle and technical details of the cutting device are described in detail below.

[0061] In this embodiment, the cutting device is composed of a rotary joint, a pipe-type tool holder and a tool. The tool is the core component of the cutting device, and its design must meet the requirements of cutting accuracy and processing efficiency. The cutting device is directly connected to the guide mechanism, and a sealing structure is formed through a flange to ensure that the potatoes maintain the stability of direction and position when entering the cutting device.

[0062] Specifically, the cutter comprises a blade body, a first cutting edge and a blade set, wherein the blade body is a hollow cone structure, the radial section is an equidistant spiral curve design, the inlet diameter is larger than the short diameter of the potato, and the outlet diameter corresponds to the thickness of the rolled strips after cutting.

[0063] As an option, the blade’s helical curve design can be adjusted to suit processing requirements. Generally, the pitch should be designed to match the target thickness of the roll, e.g. if the target thickness is 10 mm, the blade’s pitch should also be set to 10 mm to ensure that the blade’s rotation is coordinated with the potato feed motion during cutting.

[0064] The first cutting edge is arranged at the entrance of the blade body, and is used to cut the outer diameter portion of the potato into curly slices of constant thickness. As an improvement, the first cutting edge can adopt an annular blade structure, and the inner edge curvature thereof matches the spiral curve of the blade body, so as to ensure that the thickness of the cut sheet is uniform. In some embodiments, the material of the first cutting edge can be selected from high-strength stainless steel or ceramic composite materials to improve wear resistance and service life.

[0065] The blade set is arranged at equal intervals along the blade body from the inlet to the outlet, and each blade in the blade set has a second cutting edge for further cutting the roll sheet into roll strips of constant width. Specifically, the blades of the blade set can be straight blades or curved blades, and the spacing between the blades is adjusted according to the target width of the roll strip. For example, when the target width is 10 mm, the spacing of the blade set should be maintained at 10 mm.

[0066] In a possible implementation, in order to ensure the cutting effect, the blade thickness of the blade set can be set to 1 / 5 to 1 / 10 of the width of the roll strip. For example, for a roll strip with a width of 10 mm, the blade thickness can be selected to be in the range of 1 to 2 mm, which can ensure the smoothness of the cutting process and reduce the interference with the shape of the sheet.

[0067] As an improvement, the rotary joint of the cutting device is used to provide stable high-speed rotation power for the cutter, and its connection mode can adopt belt drive, chain drive or gear drive. In some embodiments, the design of the rotary joint can include high-speed bearings and sealing structures to reduce vibration and noise during the cutting process.

[0068] (4) The cut potato strips and remaining stick-shaped potato cores are discharged through the outlet

[0069] In this embodiment, step S4 is to discharge the cut strips and the remaining stick-shaped potato cores through the outlet and enter the subsequent processing link. The smooth discharge design of the cut products and the residual materials is very important, which can not only improve the production efficiency, but also ensure the integrity and quality of the materials during the processing.

[0070] Generally, the outlet of the cutting device needs to be directly connected to the discharge pipe, and the inner diameter of the discharge pipe should be designed to be slightly larger than the sum of the maximum finished product size and the residual material size after cutting to avoid clogging of the outlet.

[0071] Specifically, the outlet of the cutting device usually adopts a circular or elliptical cross-section to adapt to the natural shape of the cut material and the direction of water flow. In a possible implementation, the outlet can be designed as a structure with guide vanes, which are evenly distributed around the outlet to guide the cut potato strips and potato cores to different directions, thereby facilitating subsequent separation and processing.

[0072] In a possible implementation, the cut finished potato strips and potato cores can be transported to respective processing areas by water flow.

[0073] In general, the present invention successfully realizes the industrial processing of potato curly fries by combining hydraulic conveying, directional and rotary cutting technologies. Specifically, the water flow is used to push the potatoes into the guide mechanism so that the long axis direction is consistent with the water flow direction and stabilized in the center of the pipeline; then, the potatoes enter the cutting device and are cut into curly sheets of constant thickness and curly strips of constant width in turn under the action of the high-speed rotating cutter; after the cutting is completed, the finished fries and the residual potato core are discharged through the outlet and separated. The method has a reasonable process design, high cutting efficiency, uniform finished product specifications, and reduces the waste of raw materials, and is suitable for large-scale, continuous production.

[0074] Please see attached Figure 2 -Attached Fig. 9 The present invention also provides a cutting device for cutting fresh potato into curly fries, which is composed of a cutter and a pipeline-type cutter holder, and is used to complete the processing of potatoes under the action of high-speed water flow and rotary cutting. The specific structure and function of each component are described in detail below.

[0075] The cutter comprises a blade body, a first cutting edge and a blade set. The blade body is a hollow cone structure, and the cross section is designed as an equidistant spiral curve along the radial direction. Specifically, the inlet size of the blade body is larger than the short-direction outer diameter of the potato, and the outlet size is adapted to the cutting spacing of the first cutting edge, thereby ensuring that the entire cutting process is smooth and efficient.

[0076] The blade is the main part of the knife, made of high-strength stainless steel with excellent wear resistance and corrosion resistance. The blade supports the first cutting edge and the blade set, provides structural stability during high-speed rotation, and blocks the potatoes driven by high-speed water flow during cutting, so that they are cut thinly on the short outer diameter and continue to feed forward with the water flow.

[0077] In a possible implementation, the inlet base circle diameter of the blade is set to 10 cm, the outlet base circle diameter is 10 mm, the pitch is 10 mm, and the blade length is 20 cm. This design is not only convenient for processing and manufacturing, but also can maximize the use of raw potatoes for cutting, and is convenient for discharging the residual stick-shaped potato cores generated during the cutting process.

[0078] Specifically, the first cutting edge is arranged at the entrance of the blade body, and is used to cut the potato into a roll of constant thickness. Due to the characteristics of the equidistant spiral curve, the distance of the first cutting edge from the entrance to the exit of the blade body to the curved surface is kept constant, so that the consistency of the thickness of the cut sheet can be ensured during the potato feeding process.

[0079] The blade set is welded to the inner surface of the blade body and arranged at equal intervals from the inlet to the outlet of the blade body. Each blade in the blade set has a second cutting edge for further cutting the roll sheet into roll strips of constant width. In a possible embodiment, the blade spacing of the blade set is 10 mm, which matches the target width of the roll strip. The thickness of the blade is designed to be 1 to 2 mm to ensure a smooth cutting process while reducing interference with the shape of the roll strip.

[0080] In some embodiments, in order to adapt to potatoes of different shapes and sizes, the structure of the blade body can adopt various forms, including a hollow cone with a polygonal radial cross section, a circular hollow cone, and a partially circular hollow cylinder.

[0081] like Figure 7 As shown, in this structure, the cross section of the blade is polygonal, and the number of sides of the polygon can be designed according to the cutting requirements, such as pentagon or hexagon. This design can form a stronger cutting stability when the cutter rotates, while increasing the guiding effect on the water flow, which is suitable for situations where high stability is required during the cutting process. In addition, the polygonal corners can also be used to optimize the chip removal effect after cutting, making it easier for the residual potato core to be discharged from the outlet.

[0082] like Figure 8 As shown in the figure, the hollow cone with a circular cross-section is one of the most common blade designs. It is characterized by extremely high symmetry and stability when rotating, and is suitable for cutting potatoes of various specifications. The circular cross-section can evenly distribute the water flow pressure and avoid the variation of cutting thickness caused by uneven local water flow. This structure significantly improves the cutting efficiency and is especially suitable for continuous processing lines with high production efficiency requirements.

[0083] like Fig. 9 As shown in the figure, the partially circular hollow cylinder structure is a design that combines flexibility and cutting efficiency. Its cross section is a combination of a part of a circular arc and a straight line. This design can form a certain guiding effect in the tool, constraining the cutting trajectory of the potato within a specific range, thereby improving the cutting accuracy. At the same time, the partially circular cross section also has a strong chip removal ability, which is suitable for situations where the potato core separation is required during the processing process.

[0084] The pipeline tool holder is used to support the tool and connect it to the conveying pipeline and power source to ensure stability and efficiency during the cutting process.

[0085] The above-mentioned cutting device is described in detail below with reference to the accompanying drawings and specific embodiments.

[0086] Example:

[0087] The embodiment of the present invention provides a method and device for freshly cutting 10 mm rolled French fries, which are used in large quantities in processing plants and have an oblong potato shape, a diameter of no more than 10 cm, and a maximum strip length of no more than 20 cm.

[0088] The cutting device is composed of a rotary joint 1, a pipe-type tool holder 2, a tool 3, and a belt drive mechanism 4. Figure 2 shown.

[0089] The pipeline tool holder 2 is composed of a pipeline 21 with flanges at both ends and a pulley 22 welded on the pipeline 21. Figure 3 shown.

[0090] The tool 3 is composed of a flange 31, a blade body 32, a first cutting edge 33, and a blade set 34 composed of a plurality of blades. Each blade in the blade set 34 has a second cutting edge 341. Figure 4 shown.

[0091] The blade body 32 is the main part of the cutter 3, and plays the role of supporting the first cutting edge 33 and the blade set 34 and rotating at high speed and stability. It is made of high-strength stainless steel. The blade body can block the potatoes driven by the high-speed water flow in the long direction. After the potatoes are cut thinly on the outer diameter in the short direction by the high-speed rotation, the potatoes can continue to feed forward driven by the water flow, thereby completing the cutting of the whole potato.

[0092] The blade body 32 is a hollow cone with an equidistant spiral curve along the radial section. The base circle diameter of the equidistant spiral curve of the blade body inlet 321 is 10 cm, and the pitch is 10 mm. The base circle diameter of the equidistant spiral curve of the blade body outlet 322 is 10 mm, and the pitch is 10 mm. This is not only convenient for processing and manufacturing, but also can maximize the use of raw potatoes to cut into curly strips and facilitate the removal of chips from the remaining stick-shaped potato cores.

[0093] The blade 32 has a length of 20 centimetres.

[0094] Due to the characteristics of the equidistant spiral curve, the distance between the first cutting edge 33 and the blade curved surface is equidistantly 10 mm from the blade entrance 321 to the blade exit 322, thus ensuring that as the potato is continuously fed forward, as many rolls of a constant thickness of 10 mm as possible are cut.

[0095] The blade set 34 is welded to the blade body and arranged at an equal interval of 10 mm from the blade body entrance 321 to the blade body exit 322, so as to ensure that as many strips of 10 mm width as possible can be cut.

[0096] The first cutting edge 33 first cuts the potato into curly slices with a thickness of 10 mm, and the blade assembly 34 then cuts the curly slices into a plurality of curly strips with a width of 10 mm.

[0097] The stator 11 of the rotary joint 1 is detachably connected to the guide mechanism flange via a flange.

[0098] The rotor 12 of the rotary joint 1 is detachably connected to the tool flange 31 and the flange at one end of the pipeline tool holder 2 via the flange.

[0099] The flange at the other end of the pipeline tool holder 2 is detachably connected to the second rotor 13 of the rotary joint 1 .

[0100] The second stator 14 of the rotary joint 1 is detachably connected to the delivery pipeline flange via a flange.

[0101] The belt transmission mechanism 5 transmits the rotational power to the pipeline tool holder 2 and the tool 3 through the pulley 22, thereby realizing the rotational cutting.

[0102] During the cutting process, the high-speed water flow pushes the potatoes into the cutter inlet. First, the first cutting edge cuts the outer diameter of the potato into slices of constant thickness; then, these slices continue to move forward under the action of the water flow and the rotary motion of the cutter, and are cut into strips of constant width by the second cutting edge of each blade in the blade set. The cut strips and the remaining stick-shaped potato core are discharged from the cutter outlet and enter the subsequent separation and processing links.

[0103] The invention also provides a processing device for cutting fresh potato into curly fries, comprising a cutting device and a power transmission mechanism.

[0104] The cutting device is the structure described in detail above, including a knife and a tubular knife holder. The knife is connected to the tubular knife holder through a rotating joint and is used to cut potatoes into rolled slices of constant thickness and rolled strips of constant width under the action of water flow and high-speed rotation.

[0105] The power transmission mechanism is a structure described in detail above, including belt drive, chain drive or gear drive, which transmits power to the tool through the pipeline tool holder to achieve high-speed rotary cutting of the tool. The transmission method of the power transmission mechanism can be selected according to specific needs to adapt to different processing environments and efficiency requirements.

[0106] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
