However, it was just a guess before, but now it has been successfully verified with data.

Theoretically speaking, the more soybeans are soaked, the easier they are to crush. Soybeans that have been soaked for two days already have a flavor.

Therefore, considering the actual situation, soaking soybeans for one day and one night is enough.

In the entire system where the grinder is working, the soybean soaking time variable subordinate to the soybean variable has been measured.

——

Finally, the variable - water.

Is the crushing efficiency faster when water is added, or when no water is added? If it is faster when water is added, then how much water is added for how many beans is most efficient.

It's the same waterwheel, and it's the same sharp blade. Use soybeans that have been soaked for the same time. For the first time, without adding water, grind them for two hours. Fill a tube with soybean residue and weigh it.

The second time, I still used beans that had been soaked for a day, added water to cover the soybeans, changed to new tools, and crushed them for the same two hours. This time, because of the addition of water, the soybean dregs and water have already formed soy milk. Filter out the bean dregs and drain them.

Slurry water, dry the wet bean dregs briefly to remove part of the water, then put it into a cylinder and weigh it.

This time, the weight is a little higher.

The third time, I used beans that had been soaked for a day, added water to cover the soybeans by an inch, replaced them with new knives, and crushed them for two hours. Finally, I filtered the bean dregs, soaked the bean dregs with water and dried them, then put them into a cylinder and weighed them. The weight was higher than the previous two times.

.

This chapter is not over yet, please click on the next page to continue reading! Then, for the fourth time, add water and add half an inch more water. At the end of the weighing, the weight of the okara has not changed significantly.

The fifth time, add water and increase the height by half an inch. After weighing, the weight change is not obvious.

The sixth time, I added half an inch more water. The degree of crushing of the bean dregs seemed to have decreased.

The seventh time, when the water was increased again, the weighing weight dropped a little, and it seemed that the degree of crushing dropped even more.

…

By the tenth time, the water had been added to five and a half inches, and the weighing weight was obviously less.

Li Mengxi summarized all the weighing weights, and he found that the degree of crushing of bean dregs seemed to increase from low to high, and after reaching a certain position, it slowly gradually decreased.

This made him confused as to why the data was like this. Could it be that the machine was aging or the waterwheel was weak?

In order to verify whether there was any problem with the data, I tried again. This time, the water was only added until it was level with the soybeans, and then the soybeans were crushed for two hours. The weight was weighed, and the weight became higher again, which means that the degree of crushing also changed.

Taller.

There is no problem with the power of the waterwheel, which means there is no problem with the data.

Although I don’t know why, the crushing efficiency is not the highest when there is no water, but when there is some water, the efficiency actually drops. Although I don’t know why this is so, I don’t know what the truth is hidden in it.

, but the data shows this is the case.

Li Mengxi speculated based on the data. He derived some conclusions based on his own knowledge. First, the crushing efficiency is higher after adding water. This may be because after adding water, the power of the knife is transmitted to the water flow, and with the help of the water flow,

The power of water flow pulls a large number of soybeans at the same time, making the entire system more orderly, thus improving efficiency.

Therefore, in the initial data, the more water, the higher the crushing efficiency, which should also be related to water. The more water, the more coordinated and powerful the entire system.

But then, when the water reaches a certain level, the flow itself has resistance, and the higher the water level, the greater the water pressure at the bottom. This means that when the water reaches a certain level, the resistance brought by the water flow will slowly be offset.

Advantage.

This is just a guess.

Another guess is that water may be added to turn the entire system into a fluid. During the operation of the crusher, it is a process of continuously producing soybean residue. If there is no water, after the inner layer of soybeans is crushed,

It is not easy for the broken soybeans to be thrown to the outside, and it is not easy for the outside soybeans to contact the blade, which affects the crushing efficiency.

To put it simply, the mixture of beans and bean dregs needs to be shaken vigorously for a long time to separate the bean dregs from the beans without adding water. However, if water is added, all the bean dregs will sink to the bottom within a few turns.

It may be for this reason that after adding water, the crushing efficiency of the soymilk machine will be improved.

These are all Li Mengxi's guesses.

No matter what, no matter which guess is correct, no matter whether the truth is true or not, the data shows that anyway, the data shows that adding an appropriate amount of water can effectively improve the crushing efficiency.

Li Mengxi took a look and found that when the crushing efficiency was at its highest, the amount of water was added until it was three inches below the soybeans.

As for how much production efficiency is improved by this optimal efficiency compared with the ordinary efficiency, I don’t know. Li Mengxi doesn’t know how to divide the degree of crushing. If we talk about detailed data, the detailed data is that when the water is three inches high, after two hours of crushing, the collected

Dry the bean dregs and put them into a cylinder for weighing. At this time, the weight of the bean dregs is the heaviest, about three cents heavier than when no water is added.

In the entire system where the pulverizer is working, the [water] variable has been measured.

——

wooden barrel.

In the test of wooden barrels, Li Mengxi felt that there was no need to test the shape of the barrel. A round barrel was definitely better, and a circle was a perfect shape. But what if, what if other shapes are more efficient?

Well, what if the feeling is wrong?

Out of caution, Li Mengxi made a brief test.

Simple shapes include circles, squares, triangular shapes, ellipses, polygons, etc.

Wood processing is simple, and it didn't take long for the craftsmen to make various barrels.

In the same river, the same waterwheel, the same new knives with the same sharpness, the same soybeans soaked for a day, the same five pounds of soybeans, the difference is that the bucket cover for holding the soybeans is different, with the same height

Barrels of the same thickness but different shapes.

Then, it was shattered for two hours.

The method provided by the craftsmen is very useful. The degree of bean crushing is almost impossible to measure directly, and it is even more difficult to observe and compare. However, you only need to put the bean dregs into the tube and weigh it. Then, as long as the degree of crushing is higher, more must be packed.

No matter how small the difference is, it can be visually reflected in the weight.

The test of different wooden cylinders is over.

We weighed the bean dregs and compared the results, the shape of the wooden tube is really related to efficiency. The cylinder is the most efficient, followed by the ellipse, followed by the regular polygon, and then the square. It seems that the closer the shape is to a circle, the higher the efficiency.

Li Mengxi speculated that this may be because when wooden barrels with other shapes other than round are rotated, the water flow will continuously wash against the irregular barrel walls, causing the water flow to be messy, thus affecting the crushing efficiency.

Sure enough, the round barrel is better.

At the end of the test, Li Mengxi was almost ready to cross this step. But suddenly, Li Mengxi suddenly realized that there is a difference between a circle and a circle. There are round barrels that are as thick as the top and bottom, and some are thick at the top and thin at the bottom.

There are thin ones and thick ones, so which one is better?

Three types of cylinders were made urgently. In order to magnify the difference, the upper and lower thicknesses of the barrels were greatly different, and then the tests were carried out according to the process.

Not long after, the test results came out.

It is actually related. After weighing the weight of the crushed bean dregs from the bucket with a thick top and a thin bottom, the weight of the crushed bean dregs is obviously higher. This shows that this kind of bucket with a thick top and a thin bottom can crush the bean dregs most delicately.

Taking all the data together, this is further supported by the fact that the weighing weight of a barrel that is thick at the top and thin at the bottom is greater than that of a barrel that is generally thick at the top and bottom, and weighs more than a barrel that is thin at the top and thick at the bottom.

It seems that the thicker the upper edge of the barrel and the thinner the lower edge, the higher the crushing efficiency.

This chapter is not over, please click on the next page to continue reading! But why is this? Why is this so.

With Li Mengxi's poor knowledge, it was difficult for him to discover the truth hidden in the data.

In a daze, his memory came back, and Li Mengxi suddenly remembered that the soymilk machines in his impression were indeed cup-shaped, with a larger structure at the top and a smaller one at the bottom. Could this be the same thing?

No matter what, no matter what the reason is, the data shows that cup-shaped barrels are the most efficient.

Then, use this shape as the cover barrel of the crusher.

After shape, going down, is size.

The shape of the barrel has been determined, it is a round barrel with a larger upper part and a smaller lower part. The difference in the size of the bucket means that the size of the chassis is different.

Li Mengxi had no way of knowing or knowing whether the size of the barrel was related to the crushing efficiency. He could only use barrels of different sizes to test.

The buckets of different sizes used as samples are all distinguished by the bottom of the bucket. The smallest bucket bottom is only slightly larger than a circle of blades, and the largest one is as big as half a table.

On the same river, in the same position, the same waterwheel, the same gear set, replace with new blades of the same sharpness, use five pounds of soybeans soaked for the same time to crush them for two hours.

After a series of tests, it was found that the size of the barrel has a huge relationship with the crushing efficiency.

The most unexpected discovery was that Li Mengxi found that the smallest bucket, the one with the bottom slightly larger than the blade, had been two hours old, but the five kilograms of soybeans had not been completely crushed, and the bottom was covered with a thick layer.

The beans are dregs, but there are still many beans on top that are still intact.

Li Mengxi guessed that this may be because the bottom of the bucket is too small and the beans sink not smoothly enough, which is commonly known as getting stuck.

This round of statistical data regarding the size of wooden barrels is up and down again.

At the beginning, in the data, as the barrel slowly increased from the smallest to the largest, the crushing efficiency gradually increased. Li Mengxi speculated that this may be because the thicker the barrel, the beans are easier to flip and move, resulting in higher efficiency.

When the data is higher than a certain value, no matter how big the bucket is, the subsequent data begins to gradually decrease.

Li Mengxi didn't know what the reason was. Anyway, judging from the data, the efficiency was highest when the bottom of the barrel was two inches larger than the blade.

Is there any correlation between the size of the barrel and the size of the blade? If so, what is the correlation between the two? I don’t know. I’ll just wait and test again in the future.

For the barrel, after the shape and size are tested, the material is reached.

The material probably has nothing to do with efficiency. But the feeling may be wrong, and experimentation will definitely be accurate.

The only materials for making wooden barrels are wood, clay, and metal, and these three are the only ones easily available.

There is only one kind of sample made of clay, there are two kinds of metals: iron sheet and copper sheet, and there are many kinds of wood. There are more than ten kinds of wooden barrels made of various types of wood.
