In fact, if you really want to produce canned food, the technical requirements are actually quite high.

Last time, Yang Yinuan fooled the Gao family father and son, saying that he could jointly produce canned food with them.

also boasted about the benefits of this canned food and the Gao family father and son, which really made the Gao family father and son very happy.

In this era, there is no shortage of protein, especially in the northern world.

To the east of this iron city, to the south there is the vast and boundless Handa grassland, how big this grassland is, no one can say clearly.

It's just that there are countless bison and wild sheep living in this grassland, which is true.

And countless ordinary people go to the wild to hunt these bison and wild sheep in order to have a full stomach.

Although the danger is very high, in order to fill their stomachs, countless farmers still put down their hoes, pick up knives and guns and go to the grassland to become hunters every year.

However, for these hunters, there are also problems that cause them the most headaches.

It is a question of how to store the loot once it has been caught in the wild.

For example, the bison in the wild can easily weigh about 1.5 tons, and some of the larger ones can weigh up to 2 tons.

It's twice as heavy as the cow on the blue star.

On the one hand, this is due to the talent of wild animals here, and on the other hand, I want to thank this Handa grassland is so rich and beautiful, and there are countless wild grasses and wild fruits.

Let the wild creatures living here never worry about eating and drinking.

Therefore, hunting such a huge wild animal is very dangerous for hunters.

Generally, it takes several people to cooperate in order to succeed in hunting.

But the problem is that if they hunt wild animals, they are far away from their villages.

How to transport the wild stuff back is enough to give them a headache.

Even in the wild, they can divide the wild animals into several pieces, but they can carry them on horses and walk back.

If you are more than 100 kilometers away from your village, then this part of the road will be very dangerous.

Because the beef and mutton hanging on the horse's back will constantly attract all kinds of predatory beasts, such as tigers, buns, jackals, hunting dogs, and even brown bears.

And even if you can evade the tracking of these beasts, it will take you two days to walk back more than 100 kilometers.

If it's a little hotter, even if you can bring the wild stuff back, it will stink a long time ago.

Therefore, how to preserve meat is one of the most headaches for locals.

Nowadays, the larger hunting teams will not kill these wild animals on the spot, but will capture them in groups.

Then drive these wild things, and sell these live bison and wild sheep in herds to the Iron City, or the Thousand Mountains City.

In the past, the Gao family also had Qianshan Ranch, and they could buy a large number of these bison and wild sheep and send them to Qianshan Ranch to be raised in captivity.

But not now......

But they still haven't given up on buying bison and goats, after all, it's a long-term deal.

And the profits are also very large.

In the past, they had to transport a batch of cattle and sheep to the Sixteen Cities of Yanyun every year, and these were all hard currency.

After all, although these bison and wild sheep are not very rare on their side, if they get those farming areas in the Sixteen Cities of Yanyun, they will be treasures.

There is a great shortage of cattle there, and there are even many city-states that prohibit the eating of beef.

Cattle are considered to be important strategic materials!

Every year an order is placed for them to order a batch of cattle to go over.

And they are also very good at tricks, such as castrating cattle when they send them over, so that the cattle cannot produce offspring.

In this way, there is only a constant supply of energy and they buy ......

So this business, they do it very well, and they can get back a lot of wealth every year.

And now, although there is no Qianshan Ranch, they can't break this business line.

On the one hand, they can make money, and on the other hand, they can maintain their relationship with Yanyun Sixteen Cities.

But what gave the Gao family father and son a headache was another problem.

That is, so many cattle and sheep are harvested every year, there will always be some of them, and they will die for one reason or another before they are sold to the sixteen cities of Yanyun.

So what to do with these dead cattle and sheep?

Eat a part of it yourself and reward it to your subordinates, but there will still be a large part that you can't handle.

Even if it's made into jerky, it's too late to make sausages or something.

Because sometimes these cattle and sheep will get sick for some inexplicable reason, and then die suddenly.

Sometimes it's a hot summer, and if you don't have time to deal with it, you can only watch the meat rot.

There is also a situation in which disaster strikes.

For example, there is a flood in the summer and a snow disaster in the winter.

A large number of livestock will die, and what will happen to these livestock?

It's too wasteful to just throw it away?

But even if you eat it yourself, you can't eat it at all, so what should I do?

In the past, they didn't have a good way at all, but after listening to Yang Yinuan talk about the benefits of this canned meat.

They know that with canned food, then those meats that have not had time to digest have the best place to go.

Canned directly!

And Yang Yinuan is the one who has mastered the method of making canned food!

Originally, he thought that this thing should be quite easy to make, but when he went back, he checked it and got a big head.

It turns out that this thing, like instant noodles, requires a lot of high-temperature cooking equipment.

Now it's a numb claw to look at him!

Especially for the outer skin of packaging, many canned meat are made of tinplate.

But you say that in this world, the special mother, even iron is not enough, where do you let them go to make tinplate?

So how to produce canned meat on Falken has become a problem for him.

Fortunately, Yang Yinuan soon figured it out, and he began to rummage through the information on the birth of this can on Blue Star again.

That's when I came up with a solution.

It turned out that this thing was first invented by Lu Gaoren.

At that time, the dwarf emperor of the Lu Gao people was competing with the Mi Niu Kingdom.

In order to challenge the maritime supremacy of the Miniu people, the Lugao people built a large navy.

At that time, the Mi Niu Navy was an out-and-out maritime hegemon, so Lu Gaoren's enthusiasm for being a navy was not high.

Therefore, in order to enhance people's enthusiasm for being in the navy, the dwarf emperor thought of a way to find a way to sail food.

A reward of more than 10,000 gold coins was offered to encourage people to invent food that could be stored at sea for a long time.

The last consioner, in the course of an accident, invented canning.

Then this product soon became one of the most popular foods among ocean-going sailors.

And he looked up some of these early cans, and he was amazed.

It turns out that this can is not difficult to make, and it can even be said to be quite simple......
