After the breakup, I returned to the island and the sea became my golden fishing ground.

Chapter 145

Jiang Han pushed open Zhang Haidai's door and saw Zhang Haidai holding his head and banging his head against the wall.

"Hey, what are you doing?"

"Brother Han, I'm really stupid. I can't even memorize such a small thing."

Jiang Han didn't realize the thing called talent before. He thought that he had good grades because he was also working hard.

Now seeing that Zhang Haidai worked so hard, but still couldn't memorize it. He felt that talent might really exist.

He looked at what Zhang Haidai was memorizing.

"Is it difficult?"

"Difficult."

Jiang Han: "..."

He really thought that with just a few lines of words, he could memorize it after reading it once or twice.

"You don't have to be so anxious. If you really can't pass the test, we won't test it."

"How can this be!" What Zhang Haidai wanted to do most was to help Brother Han. If he couldn't even pass the boat driving license, how could he help Brother Han do more things?

"Or we can find a way." Seeing that Zhang Haidai insisted, Jiang Han could only encourage him.

He marked those lines of words. He also explained it to Zhang Haidai again.

Zhang Haidai was stunned. After Jiang Han's explanation, it seemed that he could memorize it much better.

"Brother Han, you are so amazing. When I was studying, if you were a teacher, my grades would definitely not be so bad."

Jiang Han was speechless. If he was really an excellent teacher. Then he could teach Zhang Haidai well, and he could teach others better.

Compared with others, Zhang Haidai's grades might still be at the bottom.

Jiang Han saw that Zhang Haidai was serious again, so he left Zhang Haidai's room and went to another room.

Jiang Han turned on his mobile phone and checked the online fresh food delivery.

He checked several stores and finally found the answer in the comment area of ​​a fresh food store.

There was a customer who sent several pictures in a row.

He took pictures of the process of receiving the express and opening the package.

According to those pictures, Jiang Han saw that after opening the foam packaging box, the outermost was a bag of dry ice.

Then inside, it was wrapped with a layer of insulation bag.

This insulation bag has a layer of pearl cotton inside and a layer of silver aluminum foil outside. When he bought ice cream in the town supermarket, the clerk gave him such a bag.

Inside, there are two bags of ice bags. The fresh food is placed together with these ordinary ice bags.

From ice bags, to insulation bags, to dry ice, and finally to the outer layer of foam box, there are four layers of insurance in total.

He checked online again and found that the rise of cold chain transportation in recent years is due to the use of dry ice.

The temperature of dry ice is very low and cannot be in direct contact with seafood. So the insulation bag has two effects.

One is to prevent the temperature of the ice bag in the insulation bag from leaking too quickly, and the other is to prevent the dry ice from being too cold and freezing the seafood.

He checked other comments and found that many customers reported that the dry ice bags they received were empty. But the ice bags in the insulation bag did not melt.

In other words, dry ice transportation is effective.

Solid dry ice absorbs heat and turns into air. But it ensures the freezing effect of the fresh food in the insulation bag.

Jiang Han knew what to do immediately, and remembered that Mr. Yu from the ice shop had left him a business card.

He called Mr. Yu again, "Mr. Yu, do you have dry ice?"

"Dry ice? I can make it. But the price is a little higher." It must be more expensive than normal ice.

The dry ice here is basically bought by seafood restaurants.

The Haolaiwang Restaurant often comes to him to buy dry ice. The restaurant usually uses it when making sashimi.

So when eating sashimi in the restaurant, there will always be fairy-like white smoke. Those white smoke are the state of dry ice when it turns into gas.

Jiang Han asked about the price and felt that the price was within his acceptable range.

If his seafood is sold in this way, the selling price will definitely be higher than their local market price.

So he can't lose money.

For those high-end seafood, the packaging cost of this is almost negligible.

As for whether this method is feasible, you have to use it to know.

He checked online and found that refrigerated insulation bags can be bought online.

He ordered a batch of insulated bags online.

But it would take several days for the bags to arrive.

He went downstairs and ran to the town supermarket, "Can you sell me a few of your insulated bags?"

The salesperson was stunned for a moment, "We don't sell insulated bags here."

So Jiang Han bought a dozen popsicles and asked the clerk to pack them in refrigerated insulated bags.

When he arrived at the Holiwong Hotel, he divided the popsicles and kept the insulated bag for himself.

He carefully observed the insulated bag, which seemed to have more than two layers.

It didn't matter what the middle layer was, as long as the insulation effect was good.

It is said that using this bag alone for insulation is effective in keeping the cold.The freezing effect can last for several hours.

Meng Guo brought Jiang Han a glass of watermelon juice, "Why are you staring at a bag?"

Jiang Han took the watermelon juice and took a sip. This freshly squeezed watermelon juice tasted good.

"I am sighing. This technological development has indeed brought a lot of convenience."

If it were in the past, the fresh food delivery business would not have been able to develop at all.

Meng Guo carefully observed Jiang Han's expression, "Do you have a new channel?"

During this period, because Jiang Han's seafood is good, more and more customers come to the store.

Jiang Han didn't want to lie to her, "I'm still trying."

He turned his head and saw Meng Guo's lost face. He couldn't help but stretched out his hand and flicked her forehead, "What are you thinking? I just have the possibility of having another channel, not that I won't cooperate with you."

Meng Guo's face immediately turned red. Hearing Jiang Han say this, she finally felt a little relieved.

The last time she saw Jiang Han selling barnacles through express delivery, she felt that Jiang Han was not an ordinary person, and this small island could not hold him.

But she didn't care too much at the time, after all, there are few seafoods with strong vitality like barnacles.

But seeing Jiang Han's current state, he might really start to make a move on fresh food.

"Do you want more bags like this?" Meng Guo immediately calmed down. She became the cheerful Meng Guo again.

Jiang Han was stunned, "How many do you have?"

"Three."

Jiang Han: "..."

"I packed it when I bought it, I didn't throw it away."

Jiang Han: "..."

Jiang Han put away his bag, "Okay, give it to me."

Meng Guo didn't expect Jiang Han to really want it.

She found the three bags and gave them to Jiang Han.

Jiang Han found that the three bags Meng Guo gave him were larger than the one he bought.

And they were thicker.

Thicker, does it mean better insulation?

He didn't notice this when he placed the order online.

He found the store where he placed the order and asked the customer service.

Customer service Taotao: [The thicker the better, the more expensive it is. You ordered the regular version, and the thicker version is in another link. If the quantity is large, we can also customize it for you according to your needs. ]
