JP5114016B2 - Nozzle device for cutting solid food with high-pressure water - Google Patents

Description

This invention relates to disconnect nozzle device solid food by high-pressure water for the purpose of slicing food solid (e.g. raw potato, etc.) with high pressure water.

  Conventionally, in order to cut a solid food, it is easily cut regardless of whether it is thick or thin due to the balance between the forward speed of the food and the top and bottom of the cutting blade.

  In addition, in order to cut one piece of raw potato at a time, a necessary number of thin blades are juxtaposed to form a cutting blade, which is cut in a conventional manner.

In some cases, the other tough thin wires (for example, piano wires) are stretched in parallel, and the solid food is pressurized and cut simultaneously.

  According to the conventional cutting blade method, when a solid food is cut from one side, it can be cut sequentially with a target thickness, but there is a problem that improvement of cutting efficiency is difficult.

  Also, when thin blades are juxtaposed and piano wires are stretched in parallel, not only the thin blades are damaged, but increasing the blade thickness will cause inconvenience for the blades to be pinched, resulting in inevitably being cut It is difficult to reduce the thickness (for example, 2 mm or less). Also, in the case of a piano wire, there is a problem that it is difficult to maintain the same accuracy (sharpness) for a long time because there is a risk of sagging or breaking because the raw potato is pressed with a strong force.

  Next, when a high-pressure water jet is used, there is a problem that the thickness of the cut object becomes 10 mm or more at the minimum due to the fixture of the nozzle. Therefore, for example, there is a problem that cutting of potato chips (for example, 1 mm to 2 mm in thickness) is physically impossible.

  The present invention succeeds in keeping the interval between the high-pressure water beams narrow by time difference cutting, and solves the above-mentioned conventional problems.

  In the time difference cutting, the nozzle ridges are arranged at a small angle with respect to the traveling direction of the solid food, and the thickness of the solid food to be cut can be determined by adjusting the angle.

For example , the solid food can be moved at a constant speed, and a large number of high-pressure water beams can be jetted in parallel from above, below, or up and down at right angles to the traveling direction, and the solid food can be cut thinly by time difference cutting . Further, it is possible to a solid food causes a constant speed movement, and injected in parallel a number of high-pressure water beam from the upward and lateral direction of the traveling direction perpendicular to cut the solid food bar-like cross-section quadrilateral .

The high-pressure water beam is 200 kgf / cm ^{2 to} 3000 kgf / cm ² , and the diameter of the beam is 0.05 mm to 0.3 mm. The interval between the high-pressure water beams is 1.0 mm to 5 mm. 0.0 mm and the solid food is raw potato.

The present invention is directed to a high pressure water feed rod, a nozzle rod in which a large number of orifices for high pressure water are arranged in a straight line, across the moving direction of the solid food, one or both of the upward direction, the downward direction and the lateral direction. The nozzle device for cutting solid food is characterized in that the angle is set to be variable and a rotary shaft for angle adjustment is connected to the nozzle rod .

2. The solid food according to claim 1 , wherein two nozzle troughs are arranged in a direction perpendicular to the moving direction of the solid food, and high pressure water projected from the nozzles of each nozzle trough is crossed. It is a nozzle device for cutting .

Water pressure in said cutting material becomes uneven is less than 200 kgf / cm ^2, since no specific improve even beyond 3000 kgf / cm ^2, the cutting of relatively soft material, such as raw potato, 500 kgf / cm ^It may be ^{2 to} 1500 kgf / cm ² and varies depending on the object.

  The diameter of the beam in the present invention is 0.05 mm to 0.3 mm, but in the case of raw potatoes, the objective can be sufficiently achieved at around 0.1 mm.

  Next, by changing the angle of the nozzle rod, the interval between the high-pressure water beams becomes 1.0 mm to 5.0 mm or more, but in the case of raw potatoes, 1.0 mm to 2.5 mm is required due to product requirements. Used a lot.

  In the present invention, cutting with a high-pressure water beam is performed by water pressure with a high-pressure water beam of about 0.1 mm, so there is almost no cutting debris, and the quality of the product is adversely affected by pressure heat at the time of cutting (for example, There is no risk of thermal effects.

  In the present invention, since the solid food is cut into thin pieces by the high-pressure water beam, there is an effect that the solid food can be continuously cut efficiently and without adversely affecting the solid food.

  Further, as compared with the conventional apparatus, there is an effect that the service life of the cutting device (for example, nozzle) portion can be dramatically extended (for example, 3000 hours or more). The service life of the present invention is the service life of the nozzle, and is the wear time due to the passage of high-pressure water. Therefore, although it depends on the material of the nozzle used, long service life can be considered.

  Normally, when cutting metal or other hard objects with high-pressure fluid, fine hard particles are mixed in water, so the nozzle is also easily worn, but since fine hard particles are not mixed in cutting solid food in this invention, The service life of the nozzle is greatly extended.

  In the present invention, a nozzle rod with the nozzle orifice fixed as close as possible is installed at a small angle with respect to the traveling direction of the solid food to be cut (for example, adjusted to a nozzle interval of 1.5 mm). Is stably held (placed on a conveyor) and moved forward, it is quickly cut by a high-pressure water beam ejected from the nozzle. Although the time difference in this case varies depending on the traveling speed of the conveyor, if it is 60 mm per second, the adjacent cutting time difference is approximately 1/5 second, so there is no significant difference from the simultaneous cutting visually.

  An embodiment of the present invention will be described with reference to FIG. 1. A mesh conveyor 3 having a large number of protrusions 2 and 2 for stationaryly supporting a raw potato 1 is installed, and a number of nozzle holes 4 and 4 are installed in parallel above the conveyor 3. The nozzle rod 5 is placed horizontally (parallel to the conveyor 3) at a small angle θ (for example, 7 degrees) with respect to the traveling direction of the potato 1 (arrow 7).

  A large number of orifices 6 having nozzle holes 4 are provided in the nozzle rod 5 at regular intervals (for example, L = about 13 mm). In the above, when the potato 1 is inclined by 7 degrees with respect to the traveling direction, the interval L between the nozzle holes 4 and 4 becomes about 1.5 mm, and the potato chip material having a thickness of 1.5 mm is cut (FIG. 2).

  In the said Example, if the conveyor 3 is advanced to the direction of arrow 7, the raw potato 1 will be cut | disconnected by the thickness of 1.5 mm. In this case, if the speed of the conveyor 3 is 60 mm per second, the raw potato 1 having a length of 60 mm to 120 mm is cut into a chip material having a thickness of 1.5 mm in 1 second to 2 seconds. When cut with a high-pressure water beam, the raw potatoes proceed in their original form, and when an external force is applied, they are divided into chips.

  Referring to FIG. 3, another embodiment of the present invention will be described. A raw potato 1 is placed on a conveyor 3 with protrusions 2 and is advanced in the direction of arrow 7. A nozzle rod 5 a having a large number of nozzle holes is installed horizontally above the conveyor 3, and a nozzle rod 5 b is installed vertically to the side of the conveyor 3 where the raw potato 1 travels. When high-pressure water beams 8a and 8b are projected from the nozzle holes of the nozzle rods 5a and 5b as indicated by arrows 9 and 10, the raw potato 1 is cut vertically and horizontally by the high-pressure water beams 8a and 8b, and has a square cross section. The chip 11 is formed (FIG. 3).

  That is, by projecting parallel high-pressure water beams vertically and horizontally, the raw potato 1 is cut into a square cross section, and a large number of chips 11 are formed.

  Referring to FIG. 4, another embodiment of the present invention will be described. When the raw potato 1 is placed on the roller conveyor 12 and the roller 12 a is rotated in the direction of arrow 13, the raw potato 1 advances in the direction of arrow 17. Then, it is cut by the high-pressure water beam projected from the nozzle rod 4 or the high-pressure water beam projected from the nozzle rod 4a, so that a potato chip material is formed.

  There is a magnetized portion 12b at the end of the roller 12a, and a magnetized wheel 14 is opposed to the magnetized portion 12b with a small gap. Since the magnetizing wheel 14 is fixed to the rotating shaft 15 and one end of the rotating shaft 15 is linked to the motor 16, the roller 12a can be rotated via the magnetizing wheel 14 by turning on the motor 16. . Since the rotation in the above is a non-contact rotation, no noise is generated and dust is not generated, so that it is very hygienic. The non-contact rotation is an example, and the present invention is not limited to this.

  Referring to FIG. 5, another embodiment of the present invention will be described. Rollers 24a, 24a of roller conveyors 24, 24 arranged in a V-shape are laid in parallel while maintaining a small gap. In this case, the angles of the rollers 24a and 24a vary depending on the food to be handled, but in the case of raw potato 1, the angle is set to 60 degrees to 90 degrees.

  Each of the rollers 24a and 24a has magnetic conduction in which a magnetizing roll 25 is fixed to one shaft end portion, and a magnetizing wheel 26 is disposed in a non-contact manner on the magnetizing roll 25.

  In the above, the nozzle rods 27a, 27a are arranged obliquely at a predetermined interval, and the nozzle holes 28, 28 of each nozzle rod are equally spaced through all the nozzle holes. Therefore, the raw potato 1 is thinly cut at the interval. Since the high-pressure water beam is projected and cut from the nozzle holes 28 and 28 of the plurality of nozzle rods 27a and 27b, the time difference is cut due to the positional relationship of the nozzle holes. / 5 seconds to 1/10 seconds), there is no problem. In the figure, 30 is a motor and 31 is a conduction shaft.

  In the above, the raw potato 1 advances in the direction of the arrow 32. However, since the nozzle rods 27a and 27b are inclined with respect to this traveling direction, a considerably wide space (or a large distance between the orifices fixed to the nozzle rods 27a and 27b ( (For example, 13 mm), the nozzle holes can be spaced at an interval of 10 mm or less by slanting, and if another nozzle hole is inserted between them, the whole can be further narrowed into two equal parts (for example, 5 mm intervals). . In this way, by adjusting the angle and number of the nozzle rods, the thickness of the potato chip material can be selected from any of 1.5 mm to 5 mm.

  The rotational force of the roller is based on non-contact conduction, but other conduction means can be used.

  Referring to FIG. 6, another embodiment of the present invention will be described. An annular bulging hole 18a is provided in the middle part of the water tank 18, and several strip-like walls 18b, 18b are provided in the part with a small gap. A rotary blade 19 is installed at the bottom of the water tank 18, and the shaft 20 of the rotary blade 19 is connected to power (not shown).

  A nozzle ridge 21 is installed outside the annular bulging hole 18a, and a high-pressure water beam is ejected inward as indicated by an arrow 21a from the gap between the band-like walls 18b and 18b.

  In the above embodiment, when the rotor blade 19 is rotated (for example, 500 rpm to 1000 rpm), the water accumulated in the bottom of the water tank 18 rises as indicated by an arrow 22 by obtaining a centrifugal force, and the annular bulging hole 18a. Pops out as shown by arrow 22. Therefore, if an appropriate amount of raw potato is put into the water tank 18 (in effect, raw potato and water are continuously fed), the raw potato rises together and is cut by a high-pressure water beam. In this case, if a high-pressure water beam is projected from the nozzle hole, the raw potato 1 is cut into thin pieces and discharged as a potato chip material.

  That is, the raw potato 1 receives centrifugal force with water and rotates (or stops) in parallel with the annular bulging portion, so that it is easily cut by the high-pressure water beam, and each potato chip material 1a, 1b, 1c has a gap S. Is taken out as shown by arrow 29.

  The width and gap of the belt-like wall and the position of the nozzle that emits the high-pressure water beam are determined in consideration of the thickness of the potato chip material.
