水分蒸発、即ちａ縮が実施されるものである。That is, an operation is carried out to separate and remove water so that the solid content and water in the waste potato shochu are as close to the solid content as possible. By the way, one of the characteristics of this potato shochu waste liquid is that if its water content falls below a certain range and its temperature falls below a certain level, then... It has been confirmed that the fluidity required for evaporation for the compression operation is lost. Specifically, according to the applicant's experiments, the initial water content of the potato shochu waste liquid was approximately 9.
The water content is about 5%, but depending on its properties and characteristics, the water is gradually evaporated, and when the water drops to about 85% or less, and the temperature drops to 79°C or less, the water for evaporation starts to evaporate. It has been confirmed that liquidity is lost. Of course, as long as the water content of the potato shochu waste liquid is maintained at 85% or more, fluidity due to evaporation is not lost. In order to release moisture from the potato shochu waste liquid in order to concentrate it, we had to be careful about the fluidity characteristics of the potato shochu waste liquid. Therefore, in the past, we had no choice but to adopt the normal pressure single can concentration method. For example, it consists of a tank with a stirring means and a heated steam jacket placed around the tank.The tank contains the potato shochu waste liquid, and while stirring with the stirring means, the potato shochu waste liquid in the tank is heated by the heated steam inside the jacket. It was heated to ~80°C to evaporate water at normal or near normal pressure, causing it to shrink. This is because this normal pressure single can system can constantly maintain the temperature of potato shochu waste at 100 to 90 degrees Celsius at normal pressure or near normal pressure, and easily allows fluidity for evaporation. It is. [Problems to be Solved by the Invention] However, according to the above-mentioned prior art, (1) the water evaporation rate of the potato shochu waste liquid is slow. Therefore, it takes a long time to obtain C4 condensate at a given concentration. ■Since the evaporation capacity is small, in order to obtain a predetermined amount of effervescent liquid, it is necessary to prepare this normal pressure single can for a corresponding number of minutes, which increases both equipment and operating costs. Become. Furthermore, as the potato shochu waste liquid is exposed to high temperatures for a long time,
The quality deteriorates, and in some cases, a burnt odor develops. There are problems such as. Therefore, the reality is that this normal pressure single can system is hardly used. Therefore, the purpose of the present invention is, of course, to solve the problems in L. However, the object of the present invention is to provide a method that enables concentration using a multi-effect can that requires only 4 to 5 times less fuel consumption. More specifically, the potato shochu waste liquid has fluidity characteristics for evaporation as described above,
Simply applying a multi-effect can would not provide fluidity and would make operation impossible, but this problem can be solved and the advantages of a multi-effect can can be utilized to concentrate potato shochu waste liquid. [Means for solving the problem] In order to achieve the above object, the present invention has the following technical means. That is, the present invention provides a concentration method using a multi-effect can; the above-mentioned waste liquid is a potato shochu waste liquid, and this potato shochu waste liquid is supplied from the final stage evaporator, and then passed through each stage evaporator to the first stage evaporator. In addition to collecting the condensed liquid from the second evaporator, the moisture content of the potato shochu waste liquid in the first evaporator was reduced to 8.
While maintaining the temperature in the range of 0 to 87%, the temperature should be kept at 80 to 12%.
This is a fluidity-maintaining multi-effect a-condensation method for potato shochu waste liquid, which is characterized by the following five features: maintaining the temperature in the range of 0°C, maintaining the fluidity of the potato shochu waste liquid, and concentrating it. [Operation] According to the above method, the final concentrated liquid is collected in the first step.
The moisture content of the potato shochu waste liquid in the first stage base can is maintained in the range of 80 to 87%, and the temperature is maintained in the range of 80 to 120°C. Since the system is operated at a constant temperature, sufficient fluidity for evaporating the potato shochu waste liquid in the first stage evaporator can be obtained. Therefore, the desired al@ can be performed. The fact that the moisture content in the first stage is maintained at 87 to 80% even in the second and subsequent evaporators means that in the previous stage the moisture content was higher than that, such as a quadruple effect can. Assuming that, the second stage evaporator is 90-92%, the third stage evaporator is 32-93%,
In the fourth stage evaporator at the final stage, the pressure is about 95%, so the pressure inside each evaporator is reduced, and the evaporation temperature under reduced pressure conditions is, for example, 90°C, 70°C, 50
Even if the temperature gradually decreases to ℃, the fluidity for evaporation of the potato shochu waste liquid is maintained. Therefore, concentration using the multiple effect method is easily and smoothly carried out. [Example] Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, I will briefly explain the multi-effect can itself. In this example, a 1-liter membrane falling type evaporator is used, and an example of a quadruple-effect can is shown. Of course, the present invention may also use a calandria type evaporator. Now, in the figure, 1, 2, and 3.4 are each one-stage evaporator,
The second stage evaporator, the third stage evaporator, and the fourth stage evaporator at the final stage are shown. Now, externally heated steam S is supplied to the heat exchange tube 5 of the first stage evaporator 1. External heating steam S
is provided only here. Steam S1 evaporated in the first stage evaporator l is sent to the heat exchange tube 6 of the second stage evaporator 2, and the heat exchange tube 7 of the third stage evaporator 3 is sent to the heat exchange tube 6 of the second stage evaporator 2.
The evaporated air S2 in the second-stage evaporator 2 is sent to the heat exchange tube 8 of the fourth-stage evaporator 4.
Steam S3 evaporated in the stage evaporator 3 is sent.
That is, the waste steam from the previous stage evaporator is used as the heating heat source for the evaporators 2, 3.4 in the second and subsequent stages. In order to make this possible, a vacuum pump 9 is connected to the fourth and final stage evaporator 4. In this example, the vacuum capacitor 10
, cooling tower l1 is included. It is also shown. As a result, for example, the internal pressure in the fourth stage evaporator 4 is -
868lHg, the pressure inside the third stage evaporator 3 is -526■
Intestinal Hg. The pressure inside the evaporator 2 is -234Il
mHg. 1st stage k9. The pressure inside the can 1 is maintained at approximately normal pressure, for example, 1.46 κg. Therefore, the evaporation temperature of the potato shochu waste liquid supplied into each can is, for example, 110°C in the first stage evaporator 1, and 9°C in the second stage evaporator 2.
The temperature gradually decreases to 0°C, 70°C in the third stage evaporator 3, and 50°C in the fourth stage evaporator 4. Then, the sweet potato shochu waste K is supplied from the fourth stage evaporator 4 at the final stage, and the third stage evaporator 3 and
It is sequentially supplied to the second stage evaporator 2 and the first stage evaporator 1. Then, the concentrated liquid N is recovered from the first stage evaporator 1 by the suction pump l2. Of course, this example shows an example of a thin film falling type evaporator, so in each can, the potato shochu waste liquid is circulated from bottom to top and from top to bottom by the pump eye and circulation pipe 13, and heat is generated. The structure is such that it flows down in the form of a film onto the heat exchange surface of the exchange tube, and heat is exchanged in the process. In the above, this invention maintains the moisture content of the potato shochu waste liquid in the first stage evaporator 1 in the range of 80 to 87%, and maintains the temperature in the range of 80 to 120°C during operation. This is how it was done. Based on the above configuration, heating steam S is now supplied from the outside only to the heat exchange tube 5 of the first stage evaporator 1, and the five vacuum pumps 9 are driven, and the potato shochu waste liquid K is supplied to the final stage, the fourth stage. Supplied into the evaporator 4. In this case, in the present invention, the moisture content of the potato shochu waste liquid in the first stage evaporator L is maintained in the range of 80 to 87%, and the temperature is maintained in the range of 80 to 120°C during operation. Therefore, if we focus on the first stage evaporator L, the fluidity for evaporating the potato shochu waste liquid there will not be lost. This is because the fluidity for evaporation of potato shochu waste liquid is 85% water content.
It is lost when the temperature drops below 80°C, but this is because the operation is performed within the range where fluidity is maintained as described above. The fact that the moisture content in the first stage is maintained at 87 to 80% even in the second and subsequent stage evaporators means that, for example, in the second stage evaporator 2 at the previous stage, the moisture content is maintained at 87 to 80%. 92%, for example 9 in the third stage evaporator 3
2 to 83%, and in the fourth stage evaporator 4, the initial moisture content is, for example, about 95%, so the pressure inside each evaporator is reduced, and the evaporation temperature under each reduced pressure condition gradually becomes lower. Even so, the fluidity for evaporation of the potato shochu waste liquid is maintained. For example, the second stage evaporator? In the third stage evaporator 3, the can internal pressure was 234 mmHg, the evaporation temperature was 90°C, and the third stage evaporator 3 had an internal pressure of 526 mm. ．． Filtration temperature 70℃,
In the fourth stage evaporator 4, the internal pressure is -868+smHg,
Even if the evaporation temperature is 50°C, the fluidity of the sweet potato shochu residue is maintained because the moisture content of the potato shochu waste is outside the range where fluidity is lost as described above. Therefore, in the first stage evaporator 1, the steam S from the outside and the potato shochu waste liquid are exchanged and water evaporation, that is, concentration is carried out, and in the second stage evaporator 2 and subsequent stages, the steam S from the outside is exchanged with the potato shochu waste liquid. Heat is exchanged with the waste steam of the potato shochu waste liquid in the evaporator, and moisture evaporation, that is, a-condensation, is carried out.
