Wang Shouzhe didn't pay much attention to these small episodes, but turned the topic to the main one: "By the way, second brother, the live fish in your fish stall is the most valuable, right?"
"Yes, apart from spirit fish, some high-quality live fish are the most valuable. Bass, anchovy, mandarin fish, anchovy, shad, and anchovy are all famous for their freshness and tenderness, and are very popular among wealthy businessmen and others alike. I like it, the only requirement is freshness." Wang Shouyi frowned and said, "Uncle Liu's fishing fleet has live water tanks, and after landing from the live water tanks, they need to be transported to Changning Acropolis overnight in a special carriage, and we also need to get them to Changning Acropolis in the shortest possible time. Send it to the buyer. Even if it takes a very short time, there will be many mistakes, and 60% to 70% of the 10% will die, and the value will drop by half after death, so it can only be sold as fresh fish."
After a little thought, Wang Shouzhe said: "In this way, the cost of the transportation process and the lethality of live fish are the two keys. Solving these two problems, even if the catch output does not increase, can earn a lot of extra money in a year. .”
The reason why he traveled around to inspect the various industries of the family was because he wanted to see every aspect of the production of the family industry. If he could use his thinking of modern earthlings to make some optimizations, the output of the family property could be increased.
"If the fourth brother can find a way to solve the death of live fish, it is conservatively estimated that there will be an extra seventy or eighty thousand gold per year." Wang Shouyi couldn't help feeling distressed on his face, "The ones that die are all pure profit."
"It's hard to say now, I have to see your original plan, second brother."
"Fourth brother, come with me." Wang Shouyi led Wang Shouzhe to the backyard of the other courtyard, where two carriages were parked. The difference from ordinary carriages is that they do not have passenger cars, but each has a large round wooden barrel. He said, "One of the carriages holds running water and fish, and the other only holds running water. Every hour , it is necessary to replace part of the water in the wooden bucket containing fish. But even so, if there are a little more live fish, it will still cause death. It has increased a lot."
Seeing Wang Shouyi's live fish transportation method, Wang Shouzhe's eyelids twitched. The number of valuable live fish that Uncle Liu can catch every day is not much, at most it is only one or two thousand catties a day.
To use such an astonishing means when transporting? These fish tanks are also unexpectedly crude, with no oxygen enhancement or filtration at all, just two words, change the water!
In order to change the water, even a carriage was used to fill the water. This is not enough, Wang Shouyi is planning to add another carriage
But Wang Shouzhe also knew that it was really not Wang Shouyi's fault. Because this is a basalt world, everyone is thinking about how to improve their cultivation and how to improve their personal strength.
Of course, not all human elites do not study some natural subjects. It's just that even if those people have researched some of the results, they will still cherish themselves, and all kinds of knowledge are strictly kept secret, making it difficult to spread outward.
It's not their fault. Even the knowledge that Wang Shouzhe has researched will only be used secretly by the family, and it's impossible to let him spread it to benefit other families.
When Wang Shouzhe went to work in his last life, he was an unideal salted fish. He often went fishing with his friends on holidays. He caught a lot of fish. He also bought oxygen pumps to feed the fish slowly, but it turned out that only the oxygenated fish He also died very quickly. After a little research and study, he understood some simple principles.
If you want to feed fish to eat slowly, you have to make your water tank meet three conditions.
The first is the amount of dissolved oxygen in the water. Fish need oxygen to survive, but the oxygen in the water is limited. The more fish in a bucket, the greater the oxygen consumption. This can be achieved by increasing oxygen.
The second is to clean the water quality. Fish feces and food residues will produce ammonia and nitrite, and breathing will produce nitrogen. These are the factors that kill fish, which can be solved by changing water and filtering.
The other is the temperature. The higher the temperature, the greater the activity of the fish, the more oxygen that needs to be consumed, and the more toxic substances such as ammonia produced. Therefore, it is also very effective to maintain the relatively low temperature of the water quality.
After combining these three points, the two entered Wang Shouyi's study room. After some thought, Wang Shouzhe drew a simple sketch with paper. In the barrel, this uses the simplest principle of dripping oxygen.
And in as simple a way as possible, he and Wang Shouyi popularized the principle of oxygen and toxic substances.
Wang Shouyi has been working in the fish stall for more than ten years, and he quickly understood the principle of Wang Shouzhe. He suddenly realized: "After listening to the fourth brother, I suddenly understood a lot. In the past, the elders in the family just passed down the saying to change the running water. , the reason is that the fish need to eat the vital energy in the water, and if the vital energy is not enough, the water will become stagnant and the fish will die. The fourth brother means that the method of dripping water with rain can increase the vital energy in the water, but I have never thought about it.”
"This is from ancient books. It's hard to say whether it will be effective or not. Second brother needs to do a few more experiments to compare." Wang Shouzhe nodded secretly, just be active, it's easier to understand than the awkward word oxygen.
"Fish eat live air and spit out dead air. If there is too much feces in the water, it will produce poisonous gas. Filter out the fecal poisonous gas in the water through the cotton cloth layer, crushed charcoal, and gravel layer. The water is non-toxic, and the fish will naturally not die. Why didn't I think of that?" ?”
The more Wang Shouyi talked, the more excited he became: "Also, the hot and cold conditions mentioned by the fourth brother are also quite reasonable. The colder the weather, the less dead fish are transported, and the more live fish die in summer. It turns out that fish are more active in hot weather, so they need more water. The more vitality you have... No wonder the transportation during the day is not as good as at night! If you add some ice to the water... "
The theory taught by Wang Shouzhe seemed to have opened the door to a new world for Wang Shouyi. Many things that had been puzzling before were all figured out at once.
"Second brother, it's fine if you understand. You can ask the craftsmen to make a few small devices to try more." Wang Shouzhe looked at the sky, "It's getting late, I have other things to deal with, so I will leave first."
As the patriarch, Wang Shouzhe didn't come to invent and create. What's more, it's easier to know than to do, let him fix those things by himself may not be able to do a good job.
As long as Wang Shouyi understood the principle, he would be able to undertake the next work.
"Fourth brother, don't leave in a hurry." Wang Shouyi held him tight, "It's rare for you to come to the fish stall once, and the second brother hasn't treated you well yet. We have dinner at Baiweixuan at noon, and we supply the live fish in that restaurant , the taste of all kinds of dishes is excellent. My second brother still has a few things that I don’t want to understand. The siphon effect drainage type you mentioned? What is the principle of using a pump to increase the vitality of the water tank? How to use the pump principle to make the water go to a higher place Walk… "
Got it!
Wang Shouzhe listened to the "100,000 whys" in his mouth. Although he was a little confused, he knew it was a good thing. Wang Shouyi has been running fish stalls for many years. If he can really get into this way, the business of fish stalls will get better and better in the future. This can be regarded as a great contribution to the family.
In this Changningwei, it is not only Wang's fish stall family, but more than ten aristocratic families are running the fish stall business. Especially the Liu family and the Zhao family are doing things on a larger scale than the Wang family.
The better their own fish stalls do, the more wealth they create, but at the same time they squeeze the living space of their opponents.
Therefore, Wang Shouzhe spent some more time, and then had a good "initiative education" with Wang Shouyi. Both the siphon effect and the manual pump require pipes. The use of pipes in this world is quite rough. There are only bamboo pipes, pottery pipes, and copper pipes, but they are barely enough.
It doesn't matter if the manual pump can't do it temporarily, use the simple siphon principle to suck out the bottom water, and ask the staff to pour water into the filter layer manually. In this way, the transportation volume of a carriage will be greatly increased, and the live fish rate will also be greatly increased.
Wang Shouyi was so fascinated by what he heard, that he even pulled Wang Shouzhe to chatter and ask questions when he was eating at Baiweixuan at noon.
"Second brother, are these Baiweixuan really the best restaurants in Changningwei?" Wang Shouzhe ate those dishes of Baiweixuan, and suddenly felt that the taste was average, but the ingredients were superior.
Of course, the level of seasoning is still higher than that of the chef of the Wang family, but there is still a big gap between the taste and the earth.
"Fourth brother, I ate 32 big coppers and 73 dimes for this meal..." Wang Shouyi's face turned dark, and he cried out for injustice, "This is all the private money that Brother Yu worked so hard to save. How can you not eat such delicious dishes?" Satisfy?"
Wang Shouzhe touched his chin, guessing that it was caused by monosodium glutamate. When he was on earth in his previous life, monosodium glutamate and chicken essence filled every corner of the food world, which had already raised the threshold of delicious food in his soul memory. to a high degree.
If MSG can be produced, can it also become an industry
