Chapter 221 Starch Extraction

"With starch, we can make other foods, including foods that can be stored for longer periods of time."

"We can have our staple food and freedom before the rice harvest."

Taro still makes up the majority of their diet, and they're getting tired of eating it every day.

Taro is the most common plant in the jungle. You don't have to put in much effort; you can dig up lots and lots of taro as long as you find a spot.

Although taro tastes good, I'm already tired of eating it after so many days.

Also, there are still a lot of taro in the fields they have cultivated, and they will be harvested soon.

Judging from the fact that several more granaries would need to be built, Shi Nianqing had already decided against building storage rooms and that it would be better to build several granaries instead.

The height of the grain silo was increased using water power to ensure it wouldn't leak when it rained.

Place some waterproof material underneath, and then put the staple food they harvested there.

In winter, you won't have to go out to find food.

Getting back to the main point, Shi Nianqing put the cleaned branches into the stone mortar that had been prepared beforehand, and after crushing them, a distinct white liquid could be seen.

This is starch. The baobab tree has a very high starch content, unlike its fruit. The pulp inside the fruit can be used to make tea, and it tastes quite good.

The root contains a lot of water and tastes somewhat like coconut, but it's not as delicious.

The branches contain a lot of starch. Shi Nianqing also knows of a similar tree called the sago palm. If she could find one, she could eat staple food every day for the next six months.

Unfortunately, no trace of this tree has been found to date.

After crushing, add water and stir, then filter with gauze.

After filtering about twice, a cloudy liquid remained on top.

The bundle of branches that Shi Nianqing brought back was quite large, but after being crushed, there wasn't actually much left.

They probably obtained about three buckets of starch water.

Set it aside to settle, while Shi Nianqing searched for trees that could be used to make a small cart.

These trees were all cut down by them before, and some were left over and placed on the side.

With trees of various shapes, you can often find the perfect tree here when you need to make any kind of tool.

Shi Nianqing quickly found several tablets that they had discarded, designed the frame of the cart in her mind, and took out all the trees to expose them to the sun.

These layers of stacked timber actually contained a large number of water containers.

In the following time, Shi Nianqing went upstairs to check on the raw rubber that had been dried.

These rubbers were piled up densely together. After drying, they felt a bit dry to the touch, but overall they were still very soft.

Squeezing it, you can still feel the elasticity. Shi Nianqing used a backlight to select some relatively dry raw rubber and brought them to the tool shed.

They opened the window of the tool shed wide and had one of the friends fan the air from the other window.

This stuff is extremely toxic; even Shi Nianqing herself had to cover her face with several layers of it. The raw rubber was boiled in a pot until it turned into a liquid, then filtered through a strainer to remove the residue, quickly yielding a clean liquid of raw rubber.

What was originally white turned black after being boiled, looking just like poison.

That's true, this stuff really is poisonous.

These liquids have a very pungent smell, and if you get too close, you can feel dizzy.

Seeing that the condition was about right, Shi Nianqing pressed down on the rubber in the pot and added 5% sulfur.

A strong smell instantly hit her face, and Shi Nianqing could feel the wind being blown out of the window by her friends.

The taste has lessened considerably, at least reducing the risk of poisoning.
Once the two ingredients had completely melted together, Shi Nianqing took the mold she had made earlier and slowly poured the liquid from the pot into it.

This stuff solidifies very quickly, in about half an hour.

It has become a beautiful tire, but this is not the final step. These tires need to be connected together, and an air valve needs to be made.

The most important point is that they still need to be put back into the mold and then slowly vulcanized at a very high temperature.

Shi Nianqing confirmed that there was no damage inside, reinstalled the mold, and placed it in the lake to carry out a slow vulcanization reaction.

This will take about two hours. During these two hours, Shi Nianqing will turn on the stove and then make the air valve by pounding.

The method of making this thing is quite simple. It just requires adding a closable device in the middle and then adding an air core on the outside.

Meanwhile, a pot on the side was boiling new rubber, and Shi Nianqing was preparing to make a long tube, as long as possible.

This way, you can cut a piece whenever it's needed, no matter where it's used.

Most importantly, Shi Nianqing wanted to install a pipe on the water tower. The pipes that had been installed before were all made of iron, which would rust over time. If rubber water pipes could be mass-produced, Shi Nianqing would prefer to replace the iron water pipes with rubber ones.

This makes it easy to replace later, and it won't rust inside, plus the cost is much lower.

Iron can be melted down and made into other things. Shi Nianqing was making several guns. With this, one could basically do whatever one wanted on this ancient Earth. If any problems arose, one would at least have the power to resist.

Like that strange insect they encountered before, if everyone had guns, Shi Nianqing wouldn't have been so worried.

When Shi Nianqing was working, the rubber had already been completely vulcanized. When she took it out, it was bulging and was placed aside to cool.

It was at this time that Shi Nianqing used a water pipe mold to make a long water pipe and added a cooling device in the middle of the mold.

Basically, you put one end of the mold into water, and then gently pull it while pouring in the liquid, while the other side is constantly being shaped.

A long water pipe can be made quickly. Vulcanization is simple; just put it in a fire and bake it through a mold to make a smooth water pipe.

Shi Nianqing spent the entire half-day here.

My friend kept fanning the air outside the window.

Seeing the three people looking exhausted, Shi Nianqing considered whether to install a fan here. Even without electricity, she could make a simple hand-cranked fan.

With this hand-cranked fan, they won't be so tired when they're helping out from behind.

Moreover, this thing is simple to make; it can be made using only wood.
