Description

[Detailed Description of the Invention] This invention relates to a semi-automatic crystal canning sugar brewing device that semi-automatically performs the crystallizing sugar boiling process.

For example, as shown in FIG. 1, the sugar solution 3 to be roasted is poured into an upright crystallizer 1 having a calandria-type heating section 2 from the bottom via a regulating valve 4. Supplied. Heating steam 5
is applied to the heating section 2 in the crystal can 1 via the control valve 6. The sugar solution is concentrated by heating and evaporated, and the sugar solution is replenished.The fluidity of the sugar solution is measured, and when the crystallization concentration that allows crystal precipitation is reached, seed sugar is added to the sugar solution. 20 through the valve 21 to generate crystal nuclei suitable for each variety. After that, in order to prevent these crystal nuclei from combining with each other and from generating new various types of undesired crystal nuclei (pseudocrystals), sugar solution or water is supplied while monitoring the inside of the can. Continue concentration and crystal growth. When the crystals grow to a certain extent, the volume of the crystals per unit volume in Shiroshita (a mixture of sugar solution and crystals) exceeds a certain value, and the crystals come quite close to each other, a false It becomes relatively difficult for crystals to form, and it is further concentrated, making it easier for crystals to grow, and supplying sugar solution, the volume inside the can increases to a certain value, and the grain size of the crystals grows to the required size. Then, the white bottom 7 inside the can is discharged from the discharge valve 8. The discharged white flour is separated into crystals and sugar solution using a centrifuge, and the sugar solution is repeatedly used to make decoction sugar. In order to make the concentration of Shiroshita in the roasted sugar to an appropriate value, a difference of water 10 can be supplied into the can 1 through the valve 11.
The condition inside can be monitored through the viewing window 13. The steam in the can 1 is transferred to the condenser 14 through the valve 1.
5 by an air pump 16, this condenser 14 is cooled by water 18 through a valve 17. After the white undercoat 7 is discharged, steam is supplied into the can through the can washing steam valve 19 for cleaning.

It has been proposed to automatically perform such boiling sugar work. For example, the flow rate of the white bottom 7 in the can 1 is measured with a flow meter 22 such as a rheometer, the output thereof and the output setting value of the program setting device 23 are supplied to the controller 24, and the output of the controller 24 is The water difference valve 11 or the regulating valve 4 for the sugar solution 3 is controlled so that the measured flow rate becomes the set value, and the decoction is automatically performed.

In this case, the flow rate setting value program generated by the program setting device 23 differs depending on the type of sugar solution. If a set value program for one type of sugar solution is used to perform automatic decoction for another type of sugar solution, an abnormal state may occur and pseudocrystals may occur. For this reason, in the past, if the setting program for the sugar solution was not determined or the type of sugar solution was unknown, it was not possible to perform automatic decoction for the sugar solution, and the operator was forced to manually decoct the sugar solution. I was going to sugar. This manual brewing process takes a lot of time and effort, and requires many years of experience and skill.

From this point of view, this invention uses an appropriate set value program when the type of sugar solution is unknown, and uses a setting program for a different type of sugar solution to semi-automatically roast sugar, thereby reducing labor. To provide a semi-automatic sugar brewing device which reduces time and time and does not require skill.

That is, in conventional manual decanting, when pseudocrystals begin to appear, a relatively large amount of water is added to eliminate the pseudocrystals. Focusing on this, this invention performs automatic brewing using an appropriate set value program, and when pseudocrystals occur in the roasting sugar, it switches to automatic brewing that only adds water. Since the automatic water-blending sugar is used to erase pseudocrystals, a relatively large amount of water is added at the beginning, and the setting value of this automatic water-blending sugar becomes abnormal, that is, when pseudocrystals are detected. It has been found that if the program is set based on the set value of white under flow rate at the time of occurrence, the original set value can be returned in a relatively short time.
When it returns to the original setting value, it returns to automatic brewing according to the preset program. This operation of switching to automatic pouring and returning to automatic roasting is performed while the operator monitors the condition inside the crystallizer, but there is no need to spend all time on the crystallizer, and compared to fully manual roasting. This requires less effort and time, and does not require skill.

FIG. 2 shows the main parts of the crystal can automatic brewing device according to this invention, in which, for example, a timer 30 controls the program setting device 23 of FIG. It is connected between the power supply lines 33 and 34 through the process selection switch _S1 and through the contact a of the changeover switch 32. The switch S ₁ corresponding to the current step among the plural steps in one automatic roasting process is turned on, and in that step, the program setting value changes according to the slope of the setting value-time characteristic determined by the timer 30. be done. When the measured output of the fluidity meter 22 matches this set value, an output is generated from the controller 24 (Fig. 1) and the contact 36
a turns on. One end of this contact 36a is connected to the power supply line 34 through a differential water brewing sugar selection contact 37 and a sugar solution brewing sugar selection contact 38, respectively, and through a differential water valve controller 39 and a sugar solution valve controller 40.
The other end is connected to the power supply line 33 through the contact a of the changeover switch 41.

Therefore, the measured flow rate matches the set value, and the contact point 36
When a is turned on, if the contact 37 is on at that time, the differential water valve controller 39 is driven to dispense a certain amount of water, and if the contact 38 is on, the sugar solution valve controller 40 is driven. A fixed amount of sugar solution is supplied.
After this process is completed, the switch
S ₁ is turned off, a selection switch (not shown) for the next process is turned on, and the program setter 23 is controlled by the timer 30 connected to it and other timers corresponding to it, and the same operation is performed. will be held. Automatic brewing is performed in this way.

In this invention, a control system is provided that only performs automatic differential water-fusing. That is, a differential water valve controller 42 is further provided, which is connected to the power supply line 34 and has a contact 3 controlled by the output of the controller 24.
6b (this contact operates simultaneously with contact 36a)
It is further connected to the power supply line 33 through the contact c of the changeover switch 41. In addition, the changeover switch 32
is interlocked with the changeover switch 41, and when the changeover switch 41 is connected to the contacts a, b, or c, the changeover switch 32 is also connected to the contacts a, b, or c. Contact a is the position of the automatic brewing sugar, contact b is the stop position, and contact c is the automatic pouring sugar position. Therefore, when the flow rate of the sugar solution becomes abnormal in automatic brewing, the changeover switches 32 and 41 are switched to the contact point c. Therefore, when the measured flow rate reaches the setting value of the program setter 23 at the time of switching, contact 3
6b is turned on, the water difference valve controller 42 is driven, a certain amount of water is poured, and this process is repeated to perform automatic water difference and decoction. When the condition inside the can 1 becomes normal due to this automatic addition of water and the sugar, this is confirmed through the peephole 13 and the changeover switches 32, 41 are turned on.
is switched to the automatic roasting sugar position, that is, contact a.

In addition, when increasing the set value of the flow rate in the above-mentioned automatic differential boiling sugar, as shown in FIG. 3 with the same reference numerals attached to the parts corresponding to those in FIG. S ₁ a - A contact 45 that is turned on for a certain period of time by the output of the controller 24 - Connected to the power supply line 34 through a controller 46 that increases the set value of the program setter 23 by a certain value. Therefore, the changeover switches 32 and 41 are connected to the contact point c, and when the measured flow rate becomes equal to the set value of the program setting device 23, the differential water valve controller 42 is driven, and a fixed amount of water is boiled. At the same time, the switch 45 switches the switches 36a, 3
6b is turned on, the controller 46 is driven, and the setting value of the program setting device 23 is set to a large value by a certain value. This operation is repeated thereafter.

As mentioned above, according to this invention, even if the type of sugar solution is unknown, automatic brewing can be performed using a set value program for a different sugar solution.
If an abnormal condition occurs in which false crystals are likely to occur, such as excessive sugar solution during the automatic roasting, simply switching the switches 32 and 41 will cause the automatic boiling sugar to change to a different temperature.
By eliminating the abnormal condition and returning to automatic roasting according to the original set value program, there is no need for a human to perform manual roasting all the time, which reduces labor accordingly.
