[0005] [Patent Document 1] Patent No. 6901789 [Patent Document 2] Patent No. 2983002 [Patent Document 3] Patent No. 6873421 Summary of the Invention [Problem to be solved by the invention]

[0006] The invention of Patent Document 1 is a method of making wasabi beads by creating drips that drip from the bottom end of a double pipe; the size of the beads can be changed by changing the ratio of the inner pipe diameter to the outer pipe diameter, but if the inner diameter of the double pipe is increased in an attempt to make beads with a larger diameter, the weight of the drip exceeds the surface tension of the drip before it reaches the specified size, so there is a problem that the diameter can only be made up to 8 mm, as described in the examples.

[0007] The invention of Patent Document 2 is a manufacturing method in which particles released from a double tubular nozzle become salmon roe-like artificial fish eggs, but there is no description of a method for changing the diameter of the salmon roe-like artificial fish eggs, and there is a problem in that it is difficult to change the diameter of the salmon roe-like artificial fish eggs.

[0008] The invention of Patent Document 3 is a method for producing beads with a diameter of about 20 mm, but because the size of the beads can be changed by changing the length between the air injection part and the bottom end of the injection nozzle, there is the problem that changing the size of the beads requires a cumbersome setup change, i.e., changing the injection nozzle. Also, because the injection nozzle of the device in Patent Document 3 is a single-walled pipe, there is the problem that it cannot produce double-layered beads such as wasabi beads, salmon roe-like artificial fish eggs, or edible beads containing vegetable oils such as lemon oil, orange oil, and mandarin oil extracted from plants.

[0009] The present invention was devised in consideration of these problems, and its objective is to provide an edible bead manufacturing apparatus that can continuously produce large edible beads containing edible oils such as vegetable oil or animal oil without changing the setup. [Means for solving the problem]

[0010] The edible beads manufacturing apparatus according to claim 1 comprises an encapsulating liquid storage tank for storing a viscous aqueous solution containing sodium alginate, an encapsulating oil storage tank for storing an edible oil containing vegetable oil or animal oil, a bead-preparing water tank for storing a calcium chloride aqueous solution, a double pipe disposed vertically above the bead-preparing water tank and having an inner pipe through which the edible oil can flow and an outer pipe through which the viscous aqueous solution can flow, an inner / outer layer forming section for beads consisting of only the outer pipe extended downward from the lower end of the double pipe, an edible oil supply intermittent means for supplying the edible oil intermittently and disposed in a pipe connecting the encapsulating oil storage tank and the inner pipe, and a supplying means for supplying the edible oil intermittently and disposed in a pipe connecting the encapsulating liquid storage tank and the outer pipe. the control unit is characterized in that the control unit is configured to control the viscous aqueous solution supply pump for supplying the viscous aqueous solution, which is disposed in a piping connected to the outer tube of the bead inner / outer layer forming unit, to separate the viscous aqueous solution while the control unit is turning on the viscous aqueous solution supply pump, to cause the edible oil supply intermittent means to repeat a cycle of putting the edible oil supply pump into a supply state for a predetermined time and then stopping the supply for a predetermined time, and to separate in the vertical direction the portion where only the viscous aqueous solution formed in the bead inner / outer layer forming unit flows down when the edible oil supply intermittent means is stopped from supplying for the predetermined time.

[0011] The edible bead manufacturing apparatus of claim 2 is characterized in that, in claim 1, the separation means comprises a compressor that supplies compressed air, an air injection unit attached to the peripheral wall of the outer tube of the inner and outer bead layer forming unit so as to be able to inject compressed air into the tube, and an electromagnetic valve interposed in the piping connecting the compressor and the air injection unit so as to be able to cut off or switch the flow of the flowing compressed air, and the control unit causes the electromagnetic valve to be able to flow compressed air and inject compressed air from the air injection unit at a timing when only the viscous aqueous solution flows down to the height of the tip of the air injection unit, thereby separating the viscous aqueous solution in the vertical direction.

[0012] The edible bead manufacturing apparatus described in claim 3 is characterized in that, in claim 1 or 2, the edible oil supply interruption means is in a form in which the edible oil supply is performed by only an edible oil supply pump, or in a form in which the edible oil supply is performed by a combination of an edible oil supply pump and an electromagnetic valve. [Effects of the Invention]

[0013] The edible bead manufacturing apparatus according to any one of claims 1 to 3 can manufacture larger beads, for example, beads with a diameter of 20 mm, by increasing the on-time of the edible oil supply interruption means that is turned on for a predetermined time, and can manufacture smaller beads, for example, beads with a diameter of 5 mm, by decreasing the on-time. In this way, by varying the predetermined time for which the edible oil supply interruption means is turned on in accordance with the size of beads to be manufactured, beads of the same size can be manufactured continuously, or beads of different sizes, for example, beads of three different sizes can be manufactured continuously in succession, without the need for a setup change.

[0014] If compressed air is injected, for example, from an air injection unit, at a location where the encapsulated edible oil flows down the inner layer and the encapsulated viscous aqueous solution flows down the outer layer, the edible oil will scatter and it will not be possible to encapsulate the edible oil within the beads. However, by intentionally creating a timing where only the viscous aqueous solution flows down and injecting compressed air at this point, only the viscous aqueous solution is separated, and clean beads encapsulating the edible oil can be produced.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The edible bead manufacturing apparatus 1 of the present invention can continuously produce edible beads 50 containing edible oil such as vegetable oil or animal oil, of any size, from large edible beads 50 with a diameter of about 20 mm to small edible beads 50 with a diameter of a few millimeters, and can produce edible beads 50 of different sizes without having to replace any parts.

[0017] The vegetable oils include citrus oils extracted from citrus fruit peels, such as mandarin oil, lemon oil, and orange oil, as well as salad oil, rapeseed oil, soybean oil, linseed oil, palm oil, sunflower oil, castor oil, rice bran oil, and corn germ oil. The animal oils include fish oil, liver oil, whale oil, pupa oil, and bone oil.

[0018] As shown in Figures 1 to 3, the edible bead manufacturing apparatus 1 of the present invention comprises an encapsulating liquid storage tank 2 for storing a viscous aqueous solution 30 containing sodium alginate, an encapsulating oil storage tank 3 for storing an edible oil 31 containing a vegetable oil or an animal oil, a bead-preparing water tank 4 for storing a calcium chloride aqueous solution 32, a double pipe 8 disposed vertically above the bead-preparing water tank 4 and having an inner pipe 6 through which the edible oil 31 can flow and an outer pipe 7 through which the viscous aqueous solution 30 can flow, a bead inner / outer layer forming section 9 consisting only of the outer pipe 7 extended downward from the lower end of the double pipe 8, an edible oil supply / discharge means 10 intermittently supplying the edible oil 31 and disposed in a piping 26 connecting the encapsulating oil storage tank 3 and the inner pipe 6, and The apparatus includes a viscous aqueous solution feed pump 11 for feeding the viscous aqueous solution 30, which is disposed in a pipe 27 connected to the outer pipe 7; a separation means 20 for the flowing viscous aqueous solution 30, which is attached to the peripheral wall of the outer pipe 7 of the beads inner / outer layer forming section 9; and a control section (not shown). The control section, while turning on the viscous aqueous solution feed pump 11, causes the edible oil feed intermittent means 10 to repeat a cycle of putting the edible oil feed pump 11 into a feeding state for a predetermined time and then stopping the feeding state for a predetermined time, and controls the separation means 20 to separate in the vertical direction the portion where only the viscous aqueous solution 30 formed in the beads inner / outer layer forming section 9 flows down when the edible oil feed intermittent means 10 is in a feeding stopped state for the predetermined time.

[0019] First, the encapsulating liquid storage tank 2 is a tank for storing a viscous aqueous solution 30 containing sodium alginate. The sodium alginate dissolves well in cold water or hot water to form a viscous aqueous solution, and when the sodium alginate aqueous solution comes into contact with the calcium chloride aqueous solution 32, ionic cross-linking occurs instantly, resulting in gelation. Therefore, sodium alginate is used as the encapsulating material for the edible beads 50.

[0020] The encapsulated oil reservoir 3 is a reservoir for storing edible oil 31, including vegetable oil or animal oil. The taste, aroma, and color of edible beads 50 vary depending on the edible oil 31, so edible beads 50 with a variety of tastes, aromas, and colors can be produced. For example, if lemon oil is used, edible beads 50 containing bright yellow lemon-flavored beads can be produced.

[0021] The bead-making tank 4 stores a calcium chloride aqueous solution 32, and has a removable storage basket 5 for storing edible beads 50. A mass enveloped in a viscous aqueous solution 30 containing sodium alginate, which falls from the inner and outer bead layer forming unit 9 installed above, is instantly transformed into a sphere by the calcium chloride solution 32, and spherical edible beads 50 with a two-layer structure are completed.

[0022] When a predetermined number of spherical edible beads 50 are formed in the storage basket 5 in a two-layer structure, the storage basket 5 is removed from the bead-making tank 4 and washed with water, and the edible beads 50 are completed.

[0023] The double pipe 8 is disposed vertically above the bead-preparing tank 4, and has an inner pipe 6 through which the edible oil 31 can flow, and an outer pipe 7 through which the viscous aqueous solution 30 can flow. As shown in Fig. 3, the edible oil 31 flows down from an opening at the top end of the inner pipe 6 of the double pipe 8, and the viscous aqueous solution 30 flows into the outer pipe 7 from holes provided in the peripheral wall of the outer pipe 7 into a ring-shaped gap between the outer peripheral surface of the inner pipe 6 and the inner peripheral surface of the outer pipe 7, and flows downward.

[0024] The inner and outer layer forming section 9 for beads is the portion consisting of only the outer tube 7 extended downward from the lower end of the double tube 8, and in the inner and outer layer forming section 9 for beads, as shown in FIG. 3, the edible oil 31 flowing down from the inner tube 6 flows down into the center portion corresponding to the inner layer, and the viscous aqueous solution 30 flowing down from the ring-shaped gap between the inner tube 6 and the outer tube 7 flows down into the outer layer outside the inner layer, forming a two-layer flow.

[0025] A separating means 20 for separating the viscous aqueous solution 30 while it is flowing down is attached to the peripheral wall of the outer tube 7 of the inner and outer bead layer forming section 9 .

[0026] The separating means 20 includes a compressor 21 for supplying compressed air 33, an air injection unit 22 attached to the peripheral wall of the outer tube 7 of the bead inner / outer layer forming unit 9 so as to be able to inject the compressed air 33 into the tube, and an electromagnetic valve 23 interposed in a pipe 28 connecting the compressor 21 and the air injection unit 22 so as to be able to cut off or switch the flow of the flowing compressed air 33. The control unit controls the electromagnetic valve 23 to enable the flow of compressed air so as to inject the compressed air 33 from the air injection unit 22 at a timing when only the viscous aqueous solution 30 flows down to the height of the tip of the air injection unit 22, thereby separating the viscous aqueous solution 30 in the vertical direction.

[0027] The compressor 21 is a compressor that generates compressed air 33, and the compressed air 33 is injected from the air injection part 22 to separate the viscous aqueous solution 30 into upper and lower parts.

[0028] The air injection unit 22 is attached to the peripheral wall of the outer tube 7 of the inner and outer bead layer forming unit 9, and injects compressed air 33 toward the viscous aqueous solution flowing down inside the outer tube. This injection separates the viscous aqueous solution 30 in the vertical direction into pieces of a size corresponding to each of the edible beads 50.

[0029] The solenoid valve 23 is interposed in the pipe 28 connecting the compressor 21 and the air injection unit 22, and is capable of blocking or switching the flow of the flowing compressed air 33, and is, for example, a two-way solenoid valve. When the solenoid valve 23 is open, the compressed air 33 is injected from the air injection unit 22, and when it is closed, the compressed air 33 is not injected from the air injection unit 22.

[0030] The cooking oil supply interruption means 10 is a means for supplying the cooking oil 31, interposed in the piping 26 connecting the encapsulated oil reservoir 3 and the upper opening of the inner pipe 6. The cooking oil supply interruption means 10 may be, for example, type A, as shown in Figure 1, in which the supply of the cooking oil 31 is controlled only by the cooking oil supply pump 10a, or type B, as shown in Figure 4, in which the supply of the cooking oil 31 is controlled by a combination of the cooking oil supply pump 10a and a two-way solenoid valve 24, as a combination of the cooking oil supply pump 10a and a solenoid valve, or type C, as shown in Figure 5, in which the supply of the cooking oil 31 is controlled by a combination of the cooking oil supply pump 10a and a three-way solenoid valve 25. The cooking oil supply interruption means 10 is not limited to these and may be any type that can control the supply of the cooking oil 31 intermittently.

[0031] In the case of form A, for example, there is a variable volumetric liquid pump 10a, and when the cooking oil supply interruption means 10 is in a supply state, the variable volumetric liquid pump 10a is turned on, and when the cooking oil supply interruption means 10 is in a supply stop state, the variable volumetric liquid pump 10a is turned off.

[0032] In the case of form B, for example, as shown in Figure 4, there is a combination of a variable quantitative liquid pump 10a and a two-way solenoid valve 24, and when the cooking oil supply interruption means 10 is set to a supply state, the variable quantitative liquid pump 10a is turned on and the two-way solenoid valve 24 is set to an open state, and when the cooking oil supply interruption means 10 is set to a supply stop state, the variable quantitative liquid pump 10a is maintained in an on state and the two-way solenoid valve 24 is controlled to a closed state.

[0033] In the case of form C, for example, as shown in Figure 5, there is a combination of a variable quantity liquid pump 10a and a three-way solenoid valve 25, and when the cooking oil supply interruption means 10 is set to a supply state, the variable quantity liquid pump 10a is turned on and the three-way solenoid valve 25 is set to a state in which it supplies cooking oil to the piping 26 connected to the inner pipe 6, and when the cooking oil supply interruption means 10 is set to a supply stop state, the variable quantity liquid pump 10a is maintained in an on state and the three-way solenoid valve 25 is controlled to return cooking oil 31 to the encapsulated oil storage tank 3 via the piping 29 connected to the encapsulated oil storage tank 3.

[0034] The cooking oil supply interruption means 10 is controlled by the control unit to be in a supplying state or a supply stop state, and supplies or stops supplying the cooking oil 31 to the inner pipe 6. During the time period when the cooking oil supply interruption means 10 is in a supply stop state, the front of the cooking oil 31 that is flowing down stops at the opening 6a at the lower end of the inner pipe 6 and stops flowing down.

[0035] The viscous aqueous solution feed pump 11 is a pump that feeds the viscous aqueous solution 30 and is interposed in the piping 27 that connects the outer tube 7 with the outer liquid reservoir 2, and is, for example, a variable volume liquid pump. The viscous aqueous solution feed pump 11 is constantly operated during the production of the edible beads 50, and continues to feed the viscous aqueous solution 30 into the annular gap between the inner circumferential surface of the outer tube 7 and the outer circumferential surface of the inner tube 6.

[0036] The control unit is connected by an electric circuit to the edible oil feed interruption means 10, the viscous aqueous solution feed pump 11, the compressor 21, and the solenoid valve 23. In addition, the control unit, the edible oil feed interruption means 10, the viscous aqueous solution feed pump 11, the compressor 21, and the solenoid valve 23 are electrically connected to a commercial power source.

[0037] The control unit controls at least the feeding state and feeding stop state of the cooking oil feed interruption means 10, and further controls to open the solenoid valve 23 and inject compressed air 33 from the tip of the air injection unit 22 at the moment when only the viscous aqueous solution 30 in the inner / outer bead layer forming unit 9 flows down to the height of the tip of the air injection unit 22, which occurs when the cooking oil feed interruption means 10 is put into the feeding stop state. The timing to open the solenoid valve 23 is set by confirming the time difference between the timing when the cooking oil feed interruption means 10 is put into the feeding stop state and the timing when only the viscous aqueous solution 30 in the inner / outer bead layer forming unit 9 flows down to the height of the tip of the air injection unit 22, and setting the time difference to be shifted to the timing of the cooking oil feed interruption means 10 feeding stop state.

[0038] The control unit repeats a cycle of turning on the viscous aqueous solution feed pump 11 and then stopping the feeding of the edible oil feed intermittent means 10 for a predetermined time, and then stopping the feeding of the edible oil feed intermittent means 10 for a predetermined time, and controls the separation means 20 to separate in the vertical direction the portion where only the viscous aqueous solution 30 formed in the beads inner / outer layer forming unit 9 flows down when the edible oil feed intermittent means 10 is stopped for the predetermined time.

[0039] By setting the time that the edible oil supply interruption means 10 is in the supply state longer, it is possible to produce spherical edible beads 50 with a larger diameter, for example, 20 mm, whereas by setting the time that the edible oil supply interruption means 10 is in the supply state shorter, it is possible to produce spherical edible beads 50 with a smaller diameter, for example, 5 mm. In this way, by changing the time setting for the supply state of the edible oil supply interruption means 10, it is possible to produce edible beads 50 of different sizes. The time setting can be done on a control panel (not shown).

[0040] The operation panel can be used to turn on and off the cooking oil supply intermittent means 10, set the supply time and supply stop time, turn on and off the viscous aqueous solution supply pump 11, turn on and off the compressor 21, set the time interval which is the timing for opening the solenoid valve 23, and turn the power on and off.

[0041] Next, the method of use will be described. As shown in Figure 1, the viscous aqueous solution 30 is stored in the encapsulating liquid storage tank 2, the edible oil 31 is stored in the encapsulating oil storage tank 3, and the calcium chloride aqueous solution 30 is stored in the bead-preparing water tank 4 having the storage basket 5 installed therein. Then, the power to the operation panel is turned on, and the control unit, the edible oil supply interruption means 10, the viscous aqueous solution supply pump 11, the compressor 21, and the solenoid valve 23 are made operable.

[0042] As shown in Figure 3, within the double pipe 8, by setting the edible oil supply interruption means 10 to a supply state, the edible oil 31 flows down while filling the inner pipe 6, and by turning on the viscous aqueous solution supply pump 11, the viscous aqueous solution 30 flows down while filling the annular gap between the inner surface of the outer pipe 7 and the outer surface of the inner pipe 6, and in the inner / outer layer forming section 9 for beads, a fluid flows down which has formed two layers, with the edible oil 31 in the inner layer which is the center and the viscous aqueous solution 30 in the outer layer.

[0043] Then, by repeatedly controlling the cooking oil supply interruption means 10 to stop supplying for a predetermined time and then to supply for a predetermined time, the two-layer portion and a portion containing only the viscous aqueous solution 30 are alternately formed in the inner / outer bead layer forming section 9, and compressed air 33 is injected from the air injection section 22 into the portion containing only the viscous aqueous solution 30, separating the portion containing only the viscous aqueous solution 30 in the vertical direction to form lumps of the two-layer portion one by one. The separated lumps are pushed downward by the compressed air 33 and fall.

[0044] The separated two-layer portion is dropped from the opening at the bottom end of the outer tube 7 of the inner and outer bead layer forming section 9, and upon contact with the calcium chloride solution 32 in the bead preparation tank 4, it instantly turns into a spherical gel, completing the edible beads 50. The completed edible beads 50 are stored in the storage basket 5, and the storage basket 5 is removed from the bead preparation tank 4, and the edible beads 50 are washed with water.
