Description

The present invention relates to an apparatus and method for treating sake lees. The present invention relates to processing equipment and processing methods.

In the process of producing shochu using potatoes, rice, barley, or the like as raw materials, solid shochu lees are produced at the stage of separation from moromi by filtering the liquid component that will become shochu.
This shochu lees has a high biochemical oxygen demand. Therefore, the disposal of shochu into rivers and the sea is prohibited, and the disposal of shochu lees, which is produced in large quantities during the production of shochu, has become a problem.
In recent years, as one of the methods of treating shochu lees to solve this problem, a method of turning this shochu lees into animal feed has been proposed. On the other hand, in the sake production process, the sake lees produced by the liquefaction preparation method are not suitable for eating, so they are mainly treated as feed and fertilizer.

As a specific example, Patent Literature 1 discloses a method for producing shochu lees feed by drying shochu lees.
In this method, the shochu lees is dried by dispersing and supplying the shochu lees slurry in the form of a mist in the combustion gas generated by burning the fuel in the pulse combustion device, and the dried shochu lees is heated by indirect heat exchange with the heat medium used for cooling the pulse combustion device, and the dried shochu lees are further dried by this heating. Then, rice bran is mixed with the shochu lees dried by this method, and the mixture is fermented to obtain feed mainly composed of dried shochu lees.

As another processing method, a method of incinerating the shochu lees has been proposed. For example, Patent Document 2 discloses a solid-liquid separation step for solid-liquid separation of shochu lees, a concentration step for producing a shochu lees concentrate by concentrating the liquid side of the shochu lees after the solid-liquid separation, and the shochu A method for recycling shochu lees, comprising a recycling step of recycling a concentrate of shochu lees, comprising a combustion step of incinerating at least a portion of the concentrate of shochu lees, and combustion heat obtained in the combustion step. A method for recycling shochu lees, which includes a steam recovery step of recovering steam using

In Patent Document 3, the dried shochu lees discharged from the vacuum dryer is pulverized with a pulverization device, primary air is supplied with a blower to make powdered fuel, and it is burned in a boiler with a powder burner, and the ash is A method for treating shochu lees, which is used as a raw material for high-quality roof tiles, has been proposed.

Further, Patent Document 4 proposes the use of a rotary kiln as a dry incineration apparatus for waste such as rice bran. Specifically, a rotary kiln for drying and incinerating waste, an incinerator that supplies hot gas to the rotary kiln, a waste supply device that supplies waste to the rotary kiln, and an external A waste dry incineration system has been proposed which consists of an exhaust stack which discharges to a

By the way, in the method of converting sake lees such as shochu lees as feed described in Patent Document 1, there is a problem that the equipment is large and the manufacturing cost of the equipment is high. In addition, when sake lees such as shochu lees are converted into feed using such an apparatus, a large amount of feed is generated, and there is a problem that it is difficult to sell a large amount of feed.

In addition, in the methods of incinerating shochu lees described in Patent Documents 2 and 3, similarly to the device of Patent Document 1, there is a problem that the size of the device increases and the manufacturing cost of the device increases. Moreover, when incinerating shochu lees, since shochu lees contain moisture, it is necessary to dry the shochu lees before combustion. In particular, when incinerating liquefied sake lees produced by high-heat liquefaction preparation, etc., which is a method of manufacturing sake, it is impossible to incinerate efficiently unless it is sufficiently dried and the moisture content is reduced. was there.

Furthermore, Patent Document 4 proposes, as a dry incineration apparatus for waste such as rice bran, a dry incineration apparatus equipped with a rotary kiln for drying and incinerating the waste and an incinerator for supplying high-temperature gas to the rotary kiln. However, since the rotary kiln waste is dried and incinerated, there was the problem that the waste incineration energy could not be effectively used.

Therefore, in order to solve the above problems, the present inventors, on the premise that the sake lees of sake and shochu are incinerated, have made the device simpler and more compact, and further suppress the cost of incineration. It was investigated.
Then, they found that the apparatus can be simplified and downsized by using a kiln as a drying apparatus and incinerating the dried sake lees in an incinerator.
Furthermore, by introducing the combustion gas obtained by burning sake lees dried in the kiln and drying the sake lees in the kiln, it is possible to reduce the drying cost, and waste oil is used as the main fuel for the combustion equipment. Since the sake lees are completely burned, the waste oil can be treated, and the combustion gas is obtained, so that the fuel used for incineration can be suppressed, and the dried sake lees discharged from the rear end of the kiln. It was found that the sake lees can be burned more completely by charging the sake lees into the incinerator from the upper part of the incinerator.
The present inventors have completed the present invention based on these findings.

By charging the sake lees S into the incinerator from the top, it can be incinerated more completely by the flame of the spiral flow F as described above.

(Processing method)
Next, a method for treating sake lees using the apparatus for treating sake lees according to the embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG.
First, the air A is supplied to the air discharge pipe 19 in the combustion furnace through the air supply pipe 18 by the blower 17, and the air A is discharged into the furnace.
After that, waste oil is fed into the incinerator from the waste oil tank 14 through the waste oil supply pipe 15 and ignited by the ignition burner 16 to generate a spiral flow F of the flame, and the combustion gas (exhaust gas) G is discharged through the exhaust gas pipe 13. into the kiln 2 through the
The introduced combustion gas (exhaust gas) has a temperature of 800° C. to 900° C. measured by the first temperature sensor 20 .

Then, the temperature inside the kiln is raised to a predetermined temperature or higher by the combustion gas G. For example, the kiln is heated until the second temperature sensor 21 reaches approximately 200°C.

After that, sake lees are put into the kiln 2 .
That is, in the process in which the combustion gas generated from the incinerator 4 is introduced into the kiln 2, the temperature of the exhaust gas is measured by the first and second temperature sensors 20 and 21, and after reaching a predetermined temperature, the exhaust gas is discharged into the kiln. A step of throwing sake lees is executed.
Thus, in the process of introducing the combustion gas generated from the incinerator 4 into the kiln 2, the temperature of the exhaust gas is measured by the first and second temperature sensors 20 and 21, and after reaching a predetermined temperature, the kiln Since the step of introducing sake lees into the chamber 2 is executed, drying of the sake lees can be efficiently performed.

Since this sake lees is a liquid (sludge) mixture of shochu lees and sake lees, as shown in FIGS. Sake lees is introduced into
The sake lees introduced into the kiln 2 are dried by combustion gas (exhaust gas) generated from the incinerator 4 .
The drying time for sake lees varies depending on the water content and viscosity of the liquid material (sludge material) in which shochu lees and sake lees are mixed, and is approximately 3 to 15 minutes.

The dry state of the sake lees discharged from the kiln 4 is adjusted by adjusting the temperature of the sake lees discharged from the kiln while maintaining the temperature of the first thermometer at 800°C to 900°C and the temperature of the second thermometer at approximately 200°C. See, this is done by adjusting the number of revolutions of the kiln.
That is, when the sake lees discharged from the kiln 2 are insufficiently dried, the rotation speed of the kiln is lowered to lengthen the residence time in the kiln 2 to sufficiently dry the sake lees. On the other hand, when sake lees are dried and burnt or carbonized, the rotation speed of the kiln is increased to shorten the retention time of sake lees in the kiln, thereby preventing burning or carbonization.

Also, the dryness of sake lees discharged from the kiln 2 can be adjusted by reducing the amount of sake lees introduced into the kiln 2 .
That is, when the sake lees discharged from the kiln 2 are not sufficiently dried, the amount of the sake lees put into the kiln 2 is reduced, and the amount of the sake lees exposed to the combustion gas is reduced to achieve sufficient drying. conduct. On the other hand, if the sake lees discharged from the kiln 2 are dried and burned or carbonized, the amount of sake lees put into the kiln 2 is increased, and the amount of sake lees exposed to the combustion gas is increased. Prevent burning or charring.
Incidentally, it is preferable to adjust the drying by adjusting the amount of sake lees put into the kiln 2 and adjusting the rotational speed of the kiln 2 .

In this way, in the step of drying the sake lees S in the kiln 2 with the combustion gas G generated from the incinerator 4, the number of rotations of the kiln 2 is controlled according to the drying state of the sake lees after passing through the kiln 2, and the incinerator is dried. After the sake lees S are dried to an incinerable state in step 4, a step of conveying the dried sake lees S to an incinerator is executed.
In this way, the process of controlling the rotation speed of the kiln 2 according to the drying state of the sake lees after passing through the kiln 2 and conveying the dried sake lees S to the incinerator 4 after the sake lees are dried to a state that can be incinerated in the incinerator is executed. Therefore, sake lees can be incinerated more completely.

The dried sake lees S are collected by a recovery hopper 3 provided at the rear end of the kiln 2 and introduced into the screw conveyor 5 from an inlet 5a at one end of the screw conveyor 5. As shown in FIG.
Then, the dried sake lees S are conveyed by the screw conveyor 5 and introduced into the incinerator 4 from the discharge port 5 b at the other end of the screw conveyor 5 .
That is, the dried sake lees S are conveyed to the incinerator 4 by the screw conveyor 5 .

The dried sake lees S are put into the incinerator 4 from the sake lees inlet 4c at the top and incinerated.
At this time, the temperature in the furnace is approximately 1200° C., and the flame is formed in the spiral flow F, so that the sake lees are almost completely burned and the incineration ash is almost zero.
Combustion gas G generated by incineration is introduced into the kiln 2 through the exhaust gas pipe 13 to dry the sake lees S in the kiln 2 .

In this way, the kiln 2 is used as a drying device, and the combustion gas G obtained by burning the sake lees S dried in the kiln in an incinerator is introduced into the kiln 2 to dry the sake lees S. Cost can be reduced. In addition, since dried sake lees are incinerated to obtain combustion gas, the amount of fuel used for incineration can be reduced.

In the above embodiment, the exhaust gas (combustion gas) is emitted from the exhaust pipe 6b to the outside. Since the exhaust gas has a high temperature, water is heated by the exhaust gas, heat exchange is performed, and energy is generated. You can try to make effective use of it.
