Chapter 158

With the installation function of the system, Chen Xin just moved an idea to install a set of fish vegetable symbiosis equipment originally placed in the storage room into the planting greenhouse, and connected several water tanks of hydroponic planting plates.

The fish vegetable symbiosis system has strict requirements on the oxygen content, pH value, total nitrogen, temperature and alkalinity of the water body, so after Chen Xin installed the equipment, although he did not let the equipment run, Chen Xin still needs to use the monitoring instrument attached to the equipment to detect the water quality to ensure that it can meet the requirements.

Fortunately, Chen Xin uses groundwater, and only adds nutrient solution to grow vegetables. There is still no problem with the water quality.

However, due to the recent rise of groundwater temperature, the temperature of water used in the shelter is somewhat high, which is also associated with the high temperature of water in the hydroponic cultivation tray in the greenhouse.

There's no problem growing vegetables, but if it's used to raise fish, unless it's tropical fish, it will make the fish a little uncomfortable.

So in the actual use, Chen Xin needs to consider the control of water temperature, lest the water temperature is too high, and fish farming becomes fish soup.

This is actually very easy to control, because the groundwater used by Chen Xin is pumped up first and then stored in the water tank. When needed, it is transported from the water tank to the water pipe in the shelter.

Therefore, as long as the groundwater with higher temperature is pumped up by the water pump, it will not be used immediately, but it will be reused after cooling for a period of time.

As for the hot spring bath that Qin LAN wanted before, it's easy to do. Just add a heat preservation water tank and put the hot water into the heat preservation water tank for heat preservation. It's even simpler. You can use it as you like.

After all, the temperature of most of the so-called hot springs is either too high or too low. There are few hot springs that are really suitable for bathing. Therefore, most of the hot springs need to be heated or cooled, and even some of them are just hot spring water transported to the pool to boil.

With these thoughts rolling in his mind, Chen Xin had no inspiration when he looked at the drawings of the dryer on the computer. He was so upset that he didn't bother to do it any more. So he simply turned off the computer, took a bath and went to bed.

The efficiency of Li Yulong's work is very high, perhaps because even in the end, there are still people under his father's hands working for him.

So he didn't let Chen Xinjiu wait. After two days, he came to the door again.

"Bruce Lee, did you get the dryer I wanted or the gauze?" Invited by Li Yulong to his luxury saloon car, sitting on the sofa, looking at Li Yulong's happy face, Chen Xin asked curiously.

Li Yulong didn't sell the key, but said with a smile: "brother Chen, you are lucky. Before you told me you wanted the dryer, I went back to find the source of goods. Guess what? I found it

"Did you really find the dryer?" When Chen Xin heard Li Yulong say this, he couldn't help showing a happy expression and asked him, "what kind of dryer, how big is it? What's the effect? "

"I found it. It's a fruit and vegetable machine used to be used in the kitchen of my father's hotel to make dried fruits. At that time, I bought a relatively large machine, which can dry about 30 to 40 kilograms of fruits at a time. It's also a LCD touch screen with intelligent temperature control. It's very good." Li Yulong looks like he's asking for credit. At the same time, he's boasting about what he's found.

After listening to Li Yulong's explanation, Chen Xin suddenly widened his eyes and said in surprise, "fruit and vegetable machine?"

"Yes, fruit and vegetable machine! Although it was used to dry fruits, I found the manual, which said that there was no problem in drying grains. And it's almost brand new. I bought it in the second half of last year, and I hardly used it. " Li Yulong did not expect to find such a thing.

Chen Xin was so excited by the situation introduced by Li Yulong that he asked him, "what about the power consumption? Is it big? "

"The power consumption is 500 watts. This thing doesn't consume as much power as an induction cooker." Li Yulong seems to know that Chen Xin wants to ask these questions, so he takes out the prepared manual and hands it to Chen Xin: "it's a little big, because it's for the hotel, but it's already towed over. It's in my car and can be dragged in at any time for brother Chen."

After receiving the manual from Li Yulong, Chen Xin seriously opened it and looked at it.

This fruit and vegetable machine is really as Li Yulong said. It's a little big, but it's not particularly big. It's less than one meter high. Although it weighs 40 kilograms according to the instructions, it's not too big.

Although you can only bake 30-40 Jin of grain at a time, some of them are very good.

So Chen Xin nodded with satisfaction and said, "it's really good. Now it's hard to find such a machine. Help me get it in."

"All right, brother Chen, you are satisfied!" Li Yulong still nodded with a smile and asked the bodyguards to help Chen Xin carry things into the shelter.

After placing the fruit and vegetable machine in a public space and putting it against the wall, it was turned on. Seeing that it could be turned on normally, Chen Xin brought a bag of rice from the corner of the wall and was ready to try the machine.Seeing this, Li Yulong asks the bodyguard to go back to the car outside first, while he happily stays with Chen Xin and helps him put the rice into the mesh tray of the fruit and vegetable machine.

Because it is the first time to use it, Chen Xin adjusted the temperature to a relatively low level and set it for only one hour. He planned to see the effect first.

Seeing Chen Xin testing the machine, Li Yulong didn't rush to go. Instead, he talked with Chen Xin about how to set up a greenhouse after he got the ground source heat pump from him.

"Bruce Lee, if you want to build a plantation, and the ground source heat pump comes from me, then the heating problem is solved, but where are you going to set up the plantation?" Chen Xin looked at Li Yulong and asked him this crucial question.

This is a very important problem, because in the current environment, even with the ground source heat pump provided by Chen Xin, it is still impossible to build a plantation on the surface, not only because of the bad environment on the surface, but also because the cold will affect the construction.

In the freezing cold, how to mix cement and build bricks?

Even if we use steel and glass to build a greenhouse, how can such a fragile structure resist the erosion of the environment?

Compared with spending a lot of resources to build plantations on the surface, it is the most reasonable way to find a suitable underground space. Even if we use manpower to dig holes in the ground, it is better than building houses on the surface.

So Chen Xin is very curious about where Li Yulong, who has won the support of the city government and his father, will choose the site of the plantation.
