Deserted Island Survival Belt System

354 Chapter 383, Refrigerator

Make ice!

On a tropical desert island, even if ice is made, it is not so easy to store it properly.

The daytime temperature of the deserted island is around 40 degrees, no amount of ice will melt, and the amount of liquid nitrogen is limited, only a few bottles were found.

Qin Fengyi has a whole package of ice making plans, the first is to build a cellar, a cellar that can keep warm without water leakage.

"For making ice, liquid nitrogen is indeed much better than saltpeter, but... there is still too little liquid nitrogen." Lin Qingxue pursed her lips, "I want to know Qin Fengyi's thoughts."

It is very simple to make ice with liquid nitrogen. Use a wooden barrel to hold some liquid nitrogen, then throw several bottles filled with water into the wooden barrel, and try to seal it as much as possible, because the temperature of liquid nitrogen is very low, at about minus 200 degrees, it will Evaporates in a short time.

Before the liquid nitrogen evaporates, a large amount of water needs to be prepared. Just fill the plastic bottle with water. After a simple calculation, there are bottle caps in the shelter, and there are hundreds of sealable bottles.

This is also thanks to the diligence in picking up marine garbage, otherwise it would be impossible to hoard so many plastic bottles. At the same time, it also shows in disguise how serious the pollution is now, and plastic garbage has begun to spread in the global ocean.

It is really difficult to make ice on a small island in the South Pacific. First of all, the high temperature all day is a big threat to the ice. At normal temperature, the ice will melt into water within a few hours.

Therefore, an ice cellar that can keep warm is needed.

"First of all, what we need to do is not ice, but something that keeps ice!" Qin Fengyi pointed to a place not far away, "There is an underground stone chamber, about 7 meters deep, and the temperature in the stone chamber is relatively low. The daytime temperature on land is 40 degrees, and the temperature in the stone chamber may be around 25 degrees."

"So, you plan to make a cellar there?" Han Xuening roughly knew the ancient way of storing ice, which is to use the ice in winter to hide in the cellar, and take some insulation measures in the cellar to form an ice cellar.

"However, the cellar alone is not enough, that requires a series of insulation measures!" Qin Fengyi said, "I remember when I was a child, there were small vendors who wrapped ice cream in quilts and sold them on the street. Melting so fast..."

"But...we don't have quilts..." Lin Qingxue blinked and said, there are silk and linen, but the gap between these things and cotton is not usually big.

"It can be replaced by other things, such as combining these foams into a box, surrounded by thick weeds to make a thick straw mat, and then putting a large number of frozen bottles into the foam box..." Qin Fengyi explained, " Now buildings are pasted with foam on the outer wall, just for insulation, I think... the foam insulation effect should be good."

"You can try..."

Lin Qingxue and Han Xuening thought about it for a while, and they felt that it was feasible. The only shortcoming was that there was too little foam. It was really difficult to make the foam box that Qin Fengyi mentioned.

"Saturday, Sunday, you go outside and bring in those hay." Qin Fengyi said to the sleeping giant ape.

"Wow woo woo..."

The giant ape reluctantly stood up slowly. When the giant ape opened up wasteland some time ago, a lot of weeds were dug out. Most of the weeds on the deserted island grew extremely lush, all at knee height.

"This is all the foam in the shelter... It's hard to make the kind of box you mentioned with such a small amount." Lin Qingxue and Han Xuening sorted out a little bit, and found a few pieces of foam. These foams were of different sizes and thicknesses.

"It can only be said that the ideal is very full, but the reality is very skinny..." Qin Fengyi's plan to use foam to build a large refrigerator fell through...

Leaving a civilized city and wanting to build, nature will always give you some problems. Don’t be discouraged when you are in trouble. Think hard, try more, and make reasonable use of everything you have. After that, you will find that most of the problems can be solved easily. .

"Let's do it step by step..." Qin Fengyi thought again, maybe he can use mud and stones to make a mud refrigerator, the thick mud should be able to insulate a little temperature, just make mud into the refrigerator to make a good insulation layer.

The giant apes have strong physical strength, and it didn't take long for them to bring in all the weeds. There were a lot of these weeds, and they were exposed to the sun for a long time, and the water in the grass was evaporated, and all the weeds turned yellow-green.

Lin Qingxue and Han Xuening started weaving the straw mats. The two girls were both ingenious, and the weaving of the straw mats went smoothly.

Qin Fengyi's work is heavier, he has to use yellow mud and stones to make a mud refrigerator.

"I'll make the mud, and you weave slowly. After the basic preparations are completed, we will try to make ice." Qin Fengyi watched the two girls weaving the straw mat so quickly, and he nodded in satisfaction.

In the yellow land by the river, there are many cacti growing here, and these cacti also have some purple fruits.

Later, you can try to pick some cactus fruits. This small red-purple fruit tastes delicious, but there are many thorns growing on it. You need to clean up these sharp thorns, otherwise you will be pricked when you taste it. Doubt about life.

"That's right here!" Qin Fengyi found a low-lying place and ordered the giant ape, "Dig a hole here, mix mud in it, and transport the mud there for me."

Dig a hole here, not only can you get the mud for making a refrigerator, but you can also make a well if you dig deeper.

Although there is a slowly flowing river next to it, the water of the river comes from the ground, and no one knows how long this river will last.

Perhaps, the source of the river will dry up due to various reasons in the next moment, and a deep well can be drilled to store fresh water.

One well, enough to feed them...

The giant ape dug the pit with an iron pickaxe, and worked very hard on Saturday and Sunday. After a few pickaxes, a hole half a meter deep and 2 meters in diameter was dug out.

The yellow soil is very viscous, and there are almost no impurities. It looks like a special soil for clay sculptures. In the yellow viscous soil, there are many earthworms. Some unlucky eggs were cut by the giant ape with an iron pick. two halves.

Qin Fengyi found some dry palm leaves, crushed them and mixed them with the mud, which can increase the adhesion of the mud.

Afterwards, all the mud was moved to the underground stone chamber, and the prototype of the mud refrigerator was made. Generally speaking, it is a mud pool, which is round in shape, with a diameter of about 2 meters and a depth of 1 meter.

The finished mud refrigerator is filled with prepared straw mats. Although the insulation of the straw mats is not as good as that of cotton quilts, it is worse than nothing.

There is a lot of dead grass in the prison cells of ancient movies, and it is obvious that this thing can indeed keep warm.

New book (Cultivation of Immortal God's Demon Pet) for collection...

The writing of this book is suspended, the subject matter is limited, and I can't continue writing at all. It has begun to become a fantasy, and the content of survival is getting less and less. It is not what I expected at the beginning.

Sorry... I did my best.
