Chapter 466: Salt Grass

Nian: "Hahaha, Bell, your eyes are still limited to survival in the wilderness, haven't you noticed that Jungle is an authentic foodie? When the other teams are still satisfied with raw fish, grilled fish, and roasted cassava, he has to match every meal with seasonings! Now with vegetable oil and salt, I believe there will be a lot of oriental food in the next show!"

Luan: "yes, hahaha, even their little dried fish is baked in cattails, how do I feel a little hungry......"

Nian: "There are also coconut crabs boiled in coconut milk, I don't get tired of watching them eat for a day, and I miss my mother's meals a little bit......"

Bell: "Hey, hey, you two, we're still doing a show, haven't you noticed? As I pointed out from the beginning, China's efficiency! This time, it's energy efficiency!"

Nian: "Ah, speaking of which, we would like to thank the Chinese team, who are striking for their efficient use of fuel and the protection of the natural resources of our islands. ”

"Whether it is the long stove or the dry leaf ditch for insulation on both sides, the utilization rate of energy is maximized, and it is always a few things that use energy at the same time, while boiling oil, it is also thickening seawater, baking desiccated coconut, drying firewood, refining knives and ....... ”

Lune: "And the pair of baskets newly made by Jungle, uh, in my eyes, that's already a craft......"

Bell: "No, no, no, don't you see the burnt blade on the side of the blade?" and when the show is over, I'm going to have to give it to me, it's the real work of art......

Lune: "In the end, Jungle seems to have obtained three chemical reagents, one from seaweed, one from shells, and one from the blend of seaweed and shells, I guess this has something to do with tomorrow's salt refining, I have never looked forward to tomorrow so much, tomorrow, Jungle will definitely show us his Chinese magic ......"

That evening, the two went for a walk by the beach, by the way, about what they were going to do tomorrow.

Li Junge carried a basket and tweezers, picking up shells on the beach like a shoveling shitman, and said while picking them up: "The ancients gave a very special name to the ashes burned from shells, called mirage. They don't know that it's actually the same lime from limestone, which is calcium oxide. Do you need alkali to make soap?"

Ayin smiled: "When I go back, I will break the soaphorn shell and scatter it, I usually use that, and rarely use things like caustic soda, because it will produce bubbles in the soap body." Lime water is also not good because the organic calcium produced is insoluble in water. ”

Li Junge said: "If you want soda, I can make it for you, baking soda is already there, and baking soda is not impossible to make." ”

Ayin smiled: "There is no need to be so troublesome, I will requisition the large and small basins tomorrow, and then find a section with the right temperature on the dragon kiln, and it will not delay your big event." ”

Li Junge said with a smile: "No matter which of us does it, as long as it can improve our lives, it will be a big deal." I'll make a few more pots later. ”

While talking, the two walked to the place where the coconut crab was caught that day.

Li Junge asked Ayin to take out the throwing rope from a distance and get ready.

No strange crabs were found, but there were obvious signs of creatures crawling in the pile of coconut shells.

Li Junge smiled: "I hope there is a play in the cage." ”

Scraped the dirt and weeds off the trap, and sure enough, there was a strange crab on one side of the two cages.

Li Junge restored the two cages, and the two began to walk back.

Ah Yin said: "The two big claws of the strange crab, no matter how hard the bamboo cage is, it will be pierced, right?

Li Junge said: "Arthropods have no IQ, I studied this thing for a long time yesterday, and finally found a similar version." ”

After speaking, he picked up a conch and picked out a hermit crab from the bamboo stick inside. "Look, I'll just say that the strange crab looks familiar, doesn't it look like it?"

Ah Yin looked at the hermit crab, which was smaller than melon seeds, and said, "Hahaha, in addition to the size, it is really a bit similar." ”

Li Junge smiled: "So, they have no motivation to escape. For example, if we were to live in a lakeside villa in Lijiagou, would you still have the heart to build a shed? I made a nest for the strange crabs so comfortable that the depth was enough, as long as they felt safe inside, they would not destroy it. ”

Ah Yin smiled: "This is born in sorrow and died in peace." ”

Li Junge said with a smile: "No, no, no, this is sacrifice and dedication to seek benevolence, no regrets!"

Ah Yin said: "Your mouth, people's strange crabs originally ate coconut well, but in a blink of an eye, you begged for mercy!"

Li Junge said with a smile: "So Zhuangzi can see it thoroughly, the big turtle of Chu in the fable he wrote once said, you send my shell to the temple to offer it to me, and Lao Tzu would rather 'drag the tail in the mud'......!

Back at the camp, Li Junge smiled and said, "Ayin, you rest first! Tomorrow morning, Meimei will have a meal of crab meat and start our chemical production! I will make another bucket and a few pots!"

……

When they got up the next day, Li Junge and Ayin went to check on Fang Qi.

Ah Yin said with a smile: "Erpi, you are doing this, as if you want to farm." ”

Li Junge said with a smile: "Don't say it, the method mentioned in Lao Song's "Heavenly Creation" is called 'planting salt'! But they are the ones who serve the crops. ”

Ayin smiled: "According to what you say, salt can still grow on its own on this ground?"

Li Junge gently brushed aside the grass ash and scooped out a small crystal from it: "Hey, hey, isn't this growing?

Ah Yin clapped his hands and laughed: "Wow!

Li Junge said: "It's not that Lao Song is powerful, well, although he is also very powerful, but he is only a recorder, and he is still a witness when he is long." The truly powerful practitioners, those are still the working people of ancient China!"

After washing, Li Junge began to cook, grabbed one of the strange crabs in the trap, and cooked a pot of coconut milk strange crab soup.

I didn't dare to cook too much, and washed the pot after eating. Today, this pot will come in handy.

Hurry up and start boiling oil, then collect the desiccated coconut on the dragon kiln, and re-spread the desiccated coconut left over from last night's coconut milk on the dragon kiln.

This matter was handed over to Ah Yin, and Li Junge began to wash the two water tanks that had just been vacated.

The water tank was washed and placed next to Fang Qi, and Li Junge began to weave a big hat with bamboo again.

Coconut palm silk was spread in the hat, and a large hat was woven to sandwich the brown silk in the middle, which resulted in a large filter with a diameter of one meter. He also built a solid shelf with a bamboo pole, placed a large hat on it, and then made a pair of buckets, picked up seawater, and filled most of the water tanks.

There are still some times when the salt is collected and the brine is poured, Li Junge made three dustpans, and the residual mortar that had been made of lime water yesterday was wiped on the dustpan with a bamboo knife and scraped flat, which is also mentioned in "Tiangong Kaiwu", called "salt pan"

Ayin boiled the rest of the oil, and got two full of thick bamboo tubes, and the oil refining project of the two officially ended, and the whole process got more than 20 catties of edible oil, as well as two or three catties of waste oil quenched with knives.

Li Junge went to filter out the oil from the quenching knife with a small coconut shredded funnel for Ayin and put it into a thick bamboo tube.

Ayin began to boil the soaphorn shell water that had been soaked overnight.

Li Junge took a flint hammer and smashed the soaked saponaria on a hard stone plate with a thickness of six or seven centimeters.

The hard stone plate was also specially rested by Li Junge, who tied two wooden nails with thin rattan, drew a circle with a radius of forty centimeters, and then roughly beat it into a circle with a flint chisel.

Grind only at the center of the circle, then grind at the center of the circle, and collect the ground bean pulp residue into a bucket of freshly made toner resin.

When the beans were smashed, the center of the stone plate also went down a centimeter or two, forming a small nest.

Add water to the bucket, rub it repeatedly, make a large bamboo colander, filter the soybean milk into the basin, and then take the remaining bean dregs to the disc nest for grinding, and then put it into a basin, scoop two scoops of soybean milk and rub it, filter out the soy milk again, and repeat it many times until the soaphorn beans are fully utilized.

Ayin, on the other hand, has already started the process of making soap.

The soaphorn water is boiled well, and Ayin determines the good concentration through the smoothness of its feel, cools it until it is lukewarm to the touch, and then filters it into a small basin and keeps it warm behind the dragon kiln.

Pour out a small pot of waste coconut oil, heat it slightly, it is lukewarm, Ayin brought the pot to the back of the dragon kiln, and began to add soaphorn water to the coconut oil, and the bamboo shovel kept stirring.

The mixture begins to heat up and gradually thickens to a pale milky yellow color, and when the slurry on the bamboo shovel drips into the pot, it does not disappear immediately, but can be stacked on top of it, and that's about it.

Pour the slurry into a bamboo tube with an inner diameter of about five cm, plug the mouth of the bamboo tube, bury the bamboo tube in the middle of the leaf insulation ditch, and let the mixture slowly saponify itself.

Then I started to make the next pot, and I poured a total of five cylinders, and the soaphorn water was not used up, but the grease was used up.

This can't be wasted, Ah Yin took out clean clothes and drove Li Junge to the stream to take a bath.

Li Junge came back after half an hour and said, "It's so refreshing, hahaha, at least rub half a catty of oil sludge!"

Ah Yin pursed her lips and smiled, took Li Junge's dirty clothes, and went to the stream to take a bath, wash her hair and wash the clothes she had changed.

It was already two or three o'clock in the afternoon, and Li Junge went to look at the grass ash in the square furrow again, the salt grass had grown old and could be collected.

The salt obtained now is called gray salt, and the plant ash has replaced the sodium ions in the saline soil, and most of the magnesium and calcium ions are in the soil.

Take a basin and scoop some gray salt into the large hat filter, drag the empty water tank to the bottom of the hat, Li Junge began to scoop the seawater and pour grass ash, and the clear salt water flowed down from the bottom of the filter and flowed into the water tank below.

After pouring most of the water in the tank, Li Junge dragged the filter to the top of the vacated empty tank, and after repeated pouring, the concentration of seawater gradually increased, and finally it became a concentrated brine close to saturation concentration.

Then Li Junge began to add the sodium hydroxide solution obtained by the mixed reaction of lime water and sodium carbonate solution to the clear concentrated brine, and the magnesium ions in the concentrated brine began to react with the hydroxide ions to form a magnesium hydroxide suspension.

After the two reacted for a while, and then added the sodium carbonate solution obtained by burning seaweed ash to the solution, the concentrated brine suddenly became more turbid, because the calcium ions in the concentrated brine met the carbonate ions and became calcium carbonate precipitates.

After waiting for a while, when the reaction was sufficient and the calcium carbonate was fully formed, Li Junge vacated the grass ash of the filter and filtered out the solution again, and most of the residual calcium and magnesium ions in the concentrated brine were removed again.
