DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below. The present invention provides a filling method and a device capable of filling a container with a solid-liquid mixture that eliminates the variation in the number of solids in a product and does not damage the solids and has a uniform color tone and flavor. For example, a method shown in FIGS. 5 and 6 is used to mix a base mix such as yogurt mix and a liquid containing solid matter such as pulp blaze, that is, a blaze and fill the container with the mixture. In FIG. 5, the base mix tank 1
The base mix 3 flows from the measuring tank 5 to the measuring section 5 while the preserving tank 2 flows the preserving tank 4 into the measuring tank 6, and the pipe 9 flows from the measuring tank 6 to the measuring tank 5 to mix with the base mix. The resulting product flows through the pipe 10 to the reservoir 7, and the pipe 12 allows the container 7 to be filled with the mixed food. In FIG. 6, the base mix tank 1 flows from the base mix 3 to the measuring section 6a, while the preservative tank 2 flows from the preserving tank 4 to the measuring section 6 and the respective liquids are mixed from the measuring sections 6 and 6a through the pipes 11 and 11a. 7
After being mixed by flowing into the container, the mixed food is filled into the container 8 from the pipe 12. FIG. 5 shows an example in which a metered preserve is injected and mixed into a metered base mix flow, and FIG. 6 shows an example in which a base mix and a preserve are metered and mixed. However, both of them show a method in which a fluid having a high solid content ratio and a fluid having no solid content or a low solid content ratio are separately measured and then filled.

FIG. 7 shows the specific device of FIG. That is, one end of the mixing pipe 10 is connected to the lower end of the base mix tank 1. The mixing tube 10 has a reduced diameter portion 13 in the middle portion. A blaze discharge pipe 14 is connected to the lower end of the blaze tank 2, and the blaze discharge pipe 14 is connected to a first cylinder 15 serving as a first pump means via a three-way valve 6. 3-way valve 6 is the first cylinder
Alternately, 15 is switched and connected to the preserve discharge pipe 14 and the reduced diameter portion 13 of the mixing pipe 10. The other end of the mixing pipe 10 is connected to the second cylinder 17 that serves as the second pump means via the second three-way valve 5, and the second three-way valve 5 is connected to the shutter 7 that serves as the filling section. There is. This second three-way valve 5 has a second cylinder 17
Are alternately switched and connected to the mixing tube 10 and the shutter 7. The shutter 7 is provided with an actuator 16 for opening and closing the shutter 7. The first cylinder 15 is connected to the air compressor 20 via a control valve 18, and the second cylinder 17 is connected to the air compressor 20 via a control valve 19. A control circuit 21 is provided to control the operation of the control valves 18,19. When the first cylinder 15 is in the suction process, the control circuit 21 uses the second cylinder 17 as the discharge process, and when the first cylinder 15 is in the discharge process, the second cylinder 17 is in the discharge process.
The control valves 18 and 19 are controlled so that 17 becomes the suction process. The control circuit 21 is also connected to the valves 6 and 5 so as to control the three-way valves 6 and 5, and in the suction process of the first cylinder 15, the first cylinder 15 is connected to the reserve discharge pipe,
In the discharge process of 15, the first cylinder 15 is changed to the reduced diameter portion of the mixing pipe 10.
Operate the 3-way valve 6 to connect to 13. Control circuit
Reference numeral 21 indicates that when the second cylinder 17 is in the suction process, the second cylinder 17 is connected to the mixing pipe 10, and when the second cylinder 17 is in the discharge process, the second cylinder 17 is connected to the shutter 7, which is the filling section. The operation of the three-way valve 5 is controlled so as to connect. In operation, the three-way valve 6 connects the preserve discharge pipe 14 to the first cylinder 15 and the three-way valve 5 connects to the second cylinder 17
Is connected to the shutter 7. Here, the suction process of the first cylinder 15 is started. The second cylinder 17 is a discharging process. The base mix in the mixing tube 10 does not flow. The preserve 4 containing solid matter is sucked from the tank 2 through the discharge pipe 14 into the first cylinder 15 by an amount determined by the stroke of the first cylinder 15. In this process the second cylinder 17
Is in the discharging step, and the mixture in the second cylinder 17 is filled into the container from the shutter 7. Next, the three-way valves 6 and 5 are switched, and the first cylinder 15 is changed to the reduced diameter portion 13 of the mixing pipe 10,
Also, the second cylinders 17 are connected to the mixing tubes 10, respectively.
Here, the first cylinder 15 is the discharge step, and the second cylinder 17 is the suction step. The base mix in the tank 1 is sucked into the second cylinder 17 through the mixing pipe 10. In this process, the preserve in the first cylinder 15 is discharged to the reduced diameter portion 13 of the mixing tube 10 and mixed with the base mix flowing through the mixing tube 10. Since the preserve is discharged to the reduced diameter portion 13 of the mixing pipe 10, the mixing with the base mix becomes uniform. The mixture sucked into the second cylinder 17 is filled into the container from the shutter 7 in the next step.

[0008] As described above, in the case of producing a solid-liquid mixture by mixing the preserve with the liquid base mix such as yogurt, it is difficult to adjust the solid-liquid mixture, especially when the viscosity of the liquid is high. This is because if the viscosity is high, a sufficient stirring effect cannot be obtained and the concentration distribution becomes non-uniform if only part of the liquid is drained. Also, when the solid matter is easily broken, the stirring itself is limited. On the other hand, if you try to put a lot of pulp, it is necessary to increase the solids ratio in the blaze, but if you increase the solids ratio in the blazing process, the flow will deteriorate in the process of continuous sterilization, or the damage to the solids will increase. There is a limit to the ratio of solids charged. Therefore, in the present invention, first, the solid content ratio of the solid-liquid mixture is adjusted.

In the present invention, in order to adjust the solid content ratio, a solid-liquid mixture which flows continuously or intermittently at a constant flow rate and which has a constant flow rate of liquid capable of adjusting the solid content ratio is continuously or intermittently passed through a separator. It is separated and extracted. Therefore, the use of the separator will be described.

In FIGS. 8, 9, 10, and 11, the double cylinder is used for separating the solid-liquid mixture, and the inner tube is composed of a perforated tube, a wire mesh, or a combination thereof, and the solid-liquid mixture is contained in the inner tube. The liquid is drawn out between the inner tube and the outer tube through the pipe and taken out to the outside. That is, in FIG. 8, 22 is a solid-liquid mixture feed pipe, 23 is a solid-liquid mixture discharge pipe in which the solid content ratio is adjusted, and a separator 24 composed of double cylinders 25 and 26 is provided between them. It is provided. The inner tube 26 is made of a perforated tube, a wire mesh, or a combination thereof, and the hole of the perforated tube includes not only a circular shape but also a slit-shaped hole. Between the inner pipe 26 and the outer pipe 25, the liquid is extracted from the solid-liquid mixture that has passed through the inner pipe 26 and is discharged to the outside from the outer extraction pipe 27. By using the separator 24 as described above, for example, a blaze having a solid content of 32% was obtained from a blaze having a solid content of 32%. Then, the distribution of the solid matter, which was removed, was uniform. This is a result of the liquid being evenly drained. Therefore, depending on the adjustment method, an arbitrary density can be switched to an arbitrary density.

FIG. 9 shows a separator 24 provided with a clogging prevention mechanism, in which the inner pipe 26 is the inner and outer double pipes 26a and 26b.
Each of them is made of a perforated pipe, a wire mesh, or a combination thereof, and the inner pipe 26a serves to prevent clogging.

FIG. 10 shows a separator in which a solid-liquid mixture is allowed to flow to the outside, and an outer pipe 25 of the separator 24 is connected to a solid-liquid mixture feed pipe 22 and a solid-liquid mixture discharge pipe 23 having a adjusted solid content ratio. Inner tube
26 is connected to the external extraction pipe 27, and the solid-liquid mixture is supplied to the external pipe 25.
The liquid enters into the inner pipe 26 from the inner pipe 26 and the separated liquid is extracted from the inner pipe 26 to the outer outlet pipe 27. Inner tube 26 is double tube 26
a and 26b, both of which are made of a perforated pipe, a wire mesh, or a combination thereof, and the pipe 26b serves to prevent clogging, but this is not necessary.

FIG. 11 shows a case in which a scraping blade is rotated as a clogging preventing mechanism. That is, 22 is a solid-liquid mixture feed pipe, 23 is a solid-liquid mixture discharge pipe having a adjusted solid content ratio, and these are connected by a double-cylindrical separator 24. The scraping blade 29, which rotates on the shaft 28, comes into contact with the inner surface and
It is designed to prevent 26 clogging. According to this, the liquid flows out of the hole of the inner pipe 26 and is discharged to the outside from the outer extraction pipe 27.

FIG. 12 shows an apparatus in which a metering pump corresponding to a solid-liquid mixture is used for feeding a solid-liquid mixture, and the liquid separated by the separator is sucked at a constant flow rate by a metering pump corresponding to the liquid. . That is, 30 is a solid-liquid mixture tank, from which the liquid is sent to the separator 24 via the pipe 22, and at that time, a metering pump 31 corresponding to the solid-liquid mixture is used. Separator
The liquid extracted from 24 passes through the metering pump 38 and the external extraction pipe.
It is collected from 27 into the liquid tank 34. The solid-liquid mixture of which the fixed rate is adjusted passes through the inner tube 26 of the separator 24 and is collected from the tube 23 into the solid-liquid mixture tank 33 of which the solid content ratio is adjusted. At that time, the solid-liquid mixture of which the solid content ratio is adjusted flows through the pipe 23 by the back pressure applying device 32. This back pressure applying device may be omitted if it is not necessary. The metering pump 31 may be composed of a piston and a cylinder. In addition, intermittent operation is also possible, and it is possible to prevent clogging by inserting reverse rotation operation during operation.

In FIG. 13, a metering pump corresponding to a solid-liquid mixture is placed after the separator, and the solid-liquid mixture is flown into the separator by suction and the separated liquid is taken out by the metering pump. . That is, the solid-liquid mixture tank 30 has a pressurizing device 35 by air, the liquid enters the separator 24 from the liquid supply pipe 22 by the pressurization, and the solid-liquid mixture with the adjusted solid content ratio is discharged to the tank 33 by the discharge pipe 23. At that time, the solid-liquid mixture of which the solid content ratio is adjusted is sucked by the metering pump 37 for liquid and is collected in the tank 33. Separator 24
The liquid separated in step 2 is piped with a metering pump 36 for solid-liquid mixtures.
Is inhaled through and collected in the tank 34.

As described above, the solid content ratio of the solid-liquid mixture can be adjusted by using the separator. In order to increase the number of solids in the product, it is necessary to increase the ratio of solids in the solid-liquid mixture, for example, pulp preserve, but it is possible to increase the ratio of solids by using the separator as described above. In the present invention, in adjusting the solid content ratio as described above, the liquid (source) extracted and separated by a separator is further mixed with the base mix and sufficiently stirred to eliminate color unevenness and homogenize the structure, and then the solid content ratio. It is characterized in that the presab prepared in (1) and the base mix prepared by mixing and stirring as described above are mixed and filled in a container.

FIG. 1 shows the present invention, in which a solid-liquid mixture tank 30 such as a pulp blame is 40% preservative and is separated by a metering pump 31 corresponding to the solid-liquid mixture via a liquid feed pipe 22.
The liquid is sent to 24, and the solid-liquid mixture of 60% in which the solid content ratio is adjusted is recovered from the discharge 23 pipe to the tank 33 via the back pressure valve 32. On the other hand, the liquid (source) discharged and separated in the separator 24 is stored in the tank 39 via the metering pump 38 from the external extraction pipe 27.
Will be collected. The tank 39 is supplied with the base mix from the base mix tank 41 via the pipe 42 and the pump 49. Therefore, the liquid (source) extracted from the separator 24 and separated is mixed and stirred by the stirrer 40. . Further, a valve 44 is provided in the middle of the external extraction pipe 27 so that a part of the liquid (source) separated and extracted can be extracted if necessary. The solid-liquid mixture in which the solid content ratio of the tank 33 is adjusted and the adjusted base mix of the tank 39 are respectively weighed by a weighing device 45.46, mixed by the mixing device 50, and filled in the container 47 of the conveyor 48. As a filling method, a metering method with a piston as shown in FIG. 7 or a dosing with a pump can be considered. Further, as shown in FIG. 2, the liquid in the mixing tank 39 of the liquid and the base mix extracted from the separator 24 is first filled in the container 47, and the solid-liquid mixture tank 33 in which the solid content ratio is adjusted in the next section. When the method of filling the container 47 with the solid substance is used, the solid substance can be topped and the appearance can be seen clearly.

In the filling of the solid-liquid mixture, the variation in the filled solid is smaller as the solid content ratio is higher. This is shown in FIG. The solid content ratio is plotted on the horizontal axis of FIG. 3, and the standard deviation of the number of solids filled is plotted on the vertical axis. When the average value of the number of solids filled in filling the solid-liquid mixture is constant, It shows the relationship between the solid content ratio of the solid-liquid mixture and the number of filled solid materials. or,
In the present invention, since the solid content ratio of the blazer is adjusted and then measured, it is possible to increase the solid content ratio and perform the measurement, and thus the variation can be reduced. In FIG. 4, the horizontal axis shows the number of solids filled and the vertical axis shows the frequency, respectively, and is a histogram of the number of solids filled when the solids ratio A <solids ratio B, and the filling amount is an average. The figure shows the case where the solidification is adjusted to be the same, and it is shown that the higher the solid content ratio is, the smaller the variation is than the lower solid content ratio.

Higher grades, or if the base mixes differ in their color (eg, red strawberry preserve and white yogurt), require considerable agitation for their uniform mixing, which is generally a solid. Causes damage to things. In addition, if mixing is performed after weighing, there is a tendency for the variation in the number of filled solids to increase. Therefore, in the present invention, the liquid (source) that has been separated and extracted is mixed with the base mix, and the mixture is uniformly mixed therein to make the color tone, flavor, stabilizer, etc. uniform. Also, the liquid (source) brought in by the solid-liquid mixture (preserve) whose proportion of solids to be filled later is adjusted.
Although there is a possibility of some color unevenness due to the above, the effect on production is very large because the color tone, flavor and the like of the whole product can be made fairly uniform by preliminary mixing. When it is desired to increase the number of solids in other products, the number of solids can be easily increased by wiping a part of the separated liquid (source) with the valve 44 of FIG. The present invention can be applied to jelly, yogurt with preserve, curry, sauce and the like.

[0020]

According to the present invention, the base mix and the liquid (source) separated and extracted by the separator are mixed and uniformly mixed so that the color tone, the flavor, the stabilizer and the like are made uniform, and then the solid content ratio is changed. Since a highly granular large pulp that does not deform the pulp itself is added, there is no variation in the number of solids in the product, and there is no damage to the solids. Fill the container with a solid-liquid mixture with a uniform color tone and flavor. You can
