After passing the fish pickling area, Yan Changqing soon brought the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes to the fish drying area.
"This is the fourth small area of the salted fish area - the fish drying area."
"All the marinated sea fish in the marinating area will be transported to this area for sun-drying."
Yan Changqing stopped at the fish drying area and introduced.
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes looked left and right, looking around at the fish drying area.
The fish drying area in front of you is different from the previous areas. The fish drying area is an indoor ventilated and breathable area.
The only thing that's special is that its top is covered with a huge transparent glass.
Under the transparent glass ceiling cover, there are criss-crossing barbed wire fences.
Workers in the fish drying area work together in pairs. One sits on the ladder and hangs the fish on the wire mesh, while the other stands below and hands the fish to the workers on the ladder.
Thousands of marinated sea fish were hung one by one under the barbed wire.
The sun shines through the glass ceiling and shines on thousands of pickled sea fish.
From all directions, the wind blows gently from time to time, causing the sea fish to sway slightly in the air, and even collide with each other.
“The glass ceiling above was installed specially to prevent the fish from getting wet by rainwater during the sun drying process, causing the fish to fail.”
Yan Changqing saw Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, who were more concerned about the glass ceiling above, so he opened his mouth to explain.
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes all nodded to express their understanding.
"what is that?!!"
Prince Zhu Biao pointed to something not far to the right that looked like a huge fan blade and wheel, and asked in shock.
Zhu Xi, Zhu Fan, Zhu Di and other princes also looked at it and found that there was a worker sitting there next to the huge fan wheel, with his left and right feet stepping on something like a pedal.
When the worker stepped on the pedal, the huge fan wheel would rotate, and then the wind would blow towards them.
"Oh, that's a human-powered windmill, adapted from a waterwheel."
"Because drying marine fish requires maintaining a ventilated environment, but because the area is so large, it is difficult for the natural wind blowing in from the outside to reach the central area."
"So in order to dehydrate marine fish faster, we made some human-powered windmills for indoor blowing."
Yan Changqing glanced at the human-powered windmill in front and explained.
The so-called human-powered windmills are actually huge fan impellers, which were the common fans in Yan Changqing's previous life.
It's just that the fans in Yan Changqing's previous life were all driven by electricity (bhff), but the fans he made are purely driven by manpower.
By stepping on the bicycle pedal under your feet, with the help of the transmission of the gear chain device, the fan impeller is driven to rotate, and then the fan impeller generates air blowing toward the salted fish facing the human-powered fan.
"A human-powered windmill like this, or a human-powered fan can also be used."
"In the entire fish drying area, there are probably hundreds of them, fixed at various locations in the fish drying area."
"Every hour, these human-powered fans blow for two quarters of an hour and then stop for six quarters of an hour."
"In this way, marine fish can be dehydrated faster, thereby further shortening the drying time of marine fish."
Yan Changqing further explains the role of these human-powered fans.
"If we had these human-powered fans, wouldn't we not have to be as tired as others fanning us in the future?!!"
Qi King Zhu Shu felt the wind blowing from the human-powered fan, and his eyes lit up.
This kind of foot-operated fan is obviously much easier than a hand-fan.
And looking at the relaxed look on the worker's face, it can be seen that the current strong wind has not reached its extreme, and it can still produce even stronger winds.
Yan Changqing glanced at Qi King Zhu Zun, nodded and said:
"Relatively speaking, this kind of foot-operated fan is indeed easier than a hand-operated fan."
"If your highnesses like it, you can go back to the capital and ask the craftsmen to make some for your highnesses."
"However, this fan has a greater purpose than just fanning it."
King Yan Zhu Di immediately became interested and asked:
"What's the bigger purpose?!!"
Yan Changqing's eyes fell on King Yan Zhu Di, and he faintly uttered three words:
"propeller!!!"
Looking at the puzzled looks of Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, Yan Changqing explained:
"The fan is placed in the air, and it can push out the ubiquitous air to create wind."
"If it is placed in the water, it can also discharge the water that is everywhere in the water, thereby forming a driving force and thus pushing the boat bed forward."
"The so-called propeller is a propeller developed based on the fan in front of you."
"This foot-operated propeller can greatly increase the speed of the ship by replacing the previous manual rocking propellers."
"Without considering the wind force, the speed of the current foot-operated propeller is about five to ten times faster than the previous human-powered propeller!!!"
Again, limited by the current objective environment and conditions, it is basically impossible to develop steam-powered propellers or electric-powered propellers.
Even if Yan Changqing is lucky enough to make a steam-powered propeller, or even an electric-powered propeller, it doesn't mean much in this era.
Because it is destined that only Yan Changqing can make such a thing by luck, and no one else has the ability to copy it!!!
And if only Yan Changqing can luckily make it by hand, it means that it will be difficult to mass-produce it.
The inability to mass-produce and manufacture means that it does not have the ability to promote equipment applications on a large scale.
If the application of equipment cannot be promoted on a large scale, it will not matter whether it is a steam-powered propeller or an electric-powered propeller.
At best, it can only be regarded as an "incredible" treasure for the people of the Ming Dynasty, rather than an artifact that can cause changes in the productivity of the Ming Dynasty!!!
So after knowing that the current main power system of Ming Dynasty ships relied on wind power and human-powered rocking propellers, he retreated and changed the human-powered rocking propellers to foot-operated propellers.
Although the source of power is still human power, at least the same human output drives the rotation of the propeller through the power transmission of mechanical gears. The final driving force generated is five to ten times that of the previous human-powered boat propellers!!!
This is also the reason why Japanese pirates and bandits at sea basically cannot escape as long as they are encountered by the Ming Navy.
After all, although the foot-operated propeller is not a dimensionality-reducing blow to the human-powered boat propeller, it still has the advantage of technological overpowering!
"If your highnesses are interested in this, you can learn more about it later when you visit the shipbuilding area."
Yan Changqing looked at the princes Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes and said gently.
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes also nodded, becoming more and more interested in the following areas.
