Unbeknownst to Achill, however, the arrival of a third caravan had completely changed the wheat harvest on Liberty Island, making it no longer a dreaded tire-dead man's job.

The Governor of Xiao Er was overjoyed, he did not expect that a series of new farm tools would be transported not from the main island of Liuqiu, but from the new business district of Marbury in the Tianzhu area!

He also received a letter of encouragement from Wu Dapeng's family.

It turned out that the first step of the war in the Tianzhu region had been successfully completed, and the great agricultural development was now underway, and the cotton fields and wheat and rice cultivation there were rapidly developing, and soon they would reach the level of western Australia, becoming the second largest overseas agricultural resource supplier of the Union Empire.

In order to facilitate the provision of new agricultural tools, the island has opened a fourth large-scale farm tool factory in the new business district of Marbury!

The equipment and technical personnel required by the fourth large-scale agricultural tool factory were transferred from the large agricultural tool factories in Liuqiu Island, Shandong and Western Australia.

The agricultural development of the Tianzhu region had natural advantages, so it was extremely important for the Federal Empire, and it had to quickly build a large farm tool factory for them alone.

The high-quality iron ore in the Tianzhu area provides high-quality raw materials for agricultural tool factories, and although the graphite crucible steelmaking method of Liuqiu Island is still low in output and high in cost, the quality of steel is easy to improve.

Therefore, it is completely possible to manufacture qualified agricultural tools.

Wu Dapeng's family also mentioned an incident in the letter, which was also brought to his attention by Lieutenant Colonel Wang Xuanbin when he was transporting the Delhi iron pillars to the main island of Liuqiu.

Everyone seems to have forgotten to collect local cultural relics, books, and research local production technology!

Wu Dapeng's family told the Governor of Xiao Er something.

He originally thought that the Federal Empire was the only place in the world where zinc was needed------ zinc could be used to make the rust-proof layer of white iron sheets, brass could be made, and it could also be used to make dry batteries------ and the world might be able to refine pure zinc from the Federal Empire!

As mentioned above, the non-ferrous metal smelter on the island uses the upper condensation method to refine zinc

The zinc smelting furnace there is rectangular in shape and is equipped with 120 reaction tanks.

The shape of the reaction tank resembles an inverted super vat, and the lower part of the tank contains siderite or calamine, that is, zinc carbonate and charcoal or pulverized coal, and the mouth is equipped with a bowl-shaped condensing cylinder.

During smelting, carbonic acid decomposes to form ZnO and CO2, the latter of which forms CO with charcoal, acting as a reducing agent and reducing the former to zinc metal.

The zinc rises to the lower temperature of the tank in the form of steam and condenses into ingots in the condensing device, so this condensation method is called condensation.

In fact, this method of condensation was invented by the ancient alchemists of the Eastern continent, and was widely used in the production of mercury from the Han Dynasty to the Tang Dynasty------ of course, they were far less large than the current federal empire.

However, what Wu Dapeng's family didn't expect was that the northern part of the Tianzhu region had already begun smelting metal zinc hundreds of years ago!

He asked people to take pictures in person, and brought him metal zinc to show him, and he believed that ------ confirmed that Tianzhu was the first place to smelt zinc.

Judging from the photos, they used sulphide ore to smelt zinc, or did they smelt it after roasting and oxidizing.

The smelting furnace is roughly square, the furnace cylinder is about 1 meter square, and 36 reaction tanks are erected on the perforated partition in the middle.

The reaction tank is in the shape of an inverted bottle, which contains a charge composed of oxide ore, dolomite and charcoal powder, and a hollow clay pipe is inserted into the tank.

During smelting, charcoal is burned on the separator for heating, and the dolomite in the reaction tank should be decomposed to form CO with charcoal, which acts as a reducing agent, and the reduced zinc vapor is condensed into ingots under the lower temperature separator through a ceramic tube.

This condensation method belongs to the downward condensing type.

The output is not low, with an annual output of 180 tons!

Therefore, Wu Dapeng's family reminded in the letter that we should not only keep our eyes on gold and silver, but also pay attention to the transportation of their cultural relics and ancient books, and pay attention to the production technology in Europe that we could not think of.

The Governor pondered for a moment, cultural relics and ancient books may be available, but what production technology will there be in this tattered European region that we can't think of?

They are still basically all-wood agricultural tools in agriculture, and they are shocked when they see our sickles------ even if they smelt steel, it will be more expensive than silver.

Bronze and wrought iron are the mainstay of their metal tools.

What is the Kingdom of Scotland in a hurry to import now? It's just a simple agricultural tool.

The second lieutenant shook his head, let's wait until we meet him.

The third year's wheat harvest was much more than Achill expected!

The harvest of wheat and barley was handed over to the coachman!!

He saw a coachman sitting easily in a light carriage made of iron pipes, driving four horses.

On the side of the carriage was a large wheel more than a man high, which kept spinning as the carriage moved forward.

If you look closely, you can see that the wheel is composed of snowy blades more than a meter long, and as the wheel turns, it directly cuts off the hateful wheat!

A little below the runner was an iron sheet, on which the cut wheat was piled up------ but there was a belt that could carry them to the cart behind, and then they were beaten into bundles, and then they fell out of the cart------ and so on, that a meal could cut down an acre of wheat!

God, how did those Orientals come up with this?!

Old Baum also looked at it for a long time, sighed and said, "That wheat is sturdy without a bunch------

Achill nodded in agreement, and the elder Baum was the best baling technique of all whites------ probably no use now.

It's effortless to cut the wheat, but you still have to suffer!

Originally, Liberty Island used a foot-operated thresher, but now it uses a pot-powered thresher.

When using the original thresher, no matter how hot the day is, you have to put on thick clothes, and you have to wrap your head and face with a scarf to cover it, even if you cover it so tightly, it is inevitable that there will be wheat mangs in to tie the meat!

At this time, there is nostalgia for the countryside of the Kingdom of England, where women did the work and they had to beat the wheat into a wooden barrel.

But it is by no means clean and fast with a foot-operated threshing machine!

Well, in order to harvest some more wheat, bear with it.

However, the new pot camel power machine thresher is unbearable!

For hours on end, the whole person was soaked in dust, grass clippings, sweat and the roar of the machine, and the long belt seemed to be able to drive forever in the flickering up and down!

The people at the mouth of the wheat threshing machine can only wave the handle all the time, and the mountain of wheat straw is all over again.

By the time the machine finally stopped, everyone's body seemed to fall apart, and they just wanted to lie on the ground.

At this time, the spitting came out, and it was no exaggeration to say that it was a large mass of thick mud, and the nostrils had to be thoroughly cleaned to resume breathing, and countless red spots were pricked out on the exposed skin of the body.

The happiest thing at the moment is to jump the whole person into the warm bath at once, and feel comfortable in the sour, and comfortable in the sour.

Trail had good luck and he was sent to thresh peanuts with a hand-cranked spoke thresher.

The freshly shoveled peanuts have the aroma of earth, and there will be no such terrible wheat mang------ an English girl shakes off the soil from the roots of peanuts and sends them to a hand-cranked spoke thresher------ and Archiel shakes them easily, and the spokes easily knock the peanuts off one by one.

Originally, they had to pull it one by one, and it was tiring.

Of course, it's easier now------ Archill smiled at the girl, what a pity, there were too many freckles on her face.
