Chapter 136： Something happened to your 4th sister

Ye Xiuqing followed Professor Jiang and soon came to an office in another teaching building.

"Old Lu, I'm here!"

The door of Professor Lu's office was not closed. Professor Jiang knocked on the door and walked in directly.

Ye Xiuqing, who went in behind him, said hello to Professor Lu for the first time.

"Ye Xiuqing is good, please sit down."

Ye Xiuqing and Professor Jiang found a chair in the office.

"Your matter, Lao Jiang told me yesterday. You want to build a machine that can seal the packaging bag, right?"

Hearing Professor Lu's words, Ye Xiuqing nodded hastily.

"Yes, I think this will keep the food longer."

"This can indeed extend the preservation time of food. However, I heard from Lao Jiang that what you want to preserve is cooked food. Generally speaking, with our country's current mechanical technology, it is difficult to achieve a complete vacuum.

Under these conditions, normal cooked food can be stored for about ten days. If the weather is hot, the storage time may be shorter, even as short as five days.

This storage time is enough to save the things you can't finish eating at home. But Lao Jiang said that you are planning to sell cooked food abroad and want to sell cooked food farther away. Some of this preservation time is too short.

Not to mention, it costs a lot of money to make a machine that can be sealed and packaged. After listening to Lao Jiang's words last night, I figured it out at home. Even if it is a lot of materials that need to be used, I can help find some substitutes. Want to make a finished machine, at least nearly 10,000 yuan.

If you count it this way, it's too untimely. "

Ye Xiuqing never thought that the first difficulty he encountered when he wanted to make his business bigger and stronger was actually food preservation.

In the last life, Ye Xiuqing did not sell vacuum cooked food. At that time, the vacuum packaging technology was much better than it is now. Moreover, the express delivery industry is very developed, even if it is mailed from one end of the motherland to the other end of the motherland, it will not take long.

Customers who receive cooked food can keep things in the refrigerator for several months.

Therefore, she had never thought that the vacuum machine of this era could keep food fresh for such a short period of time.

More importantly, most people in this era don't have access to a freezer.

Thinking of this, Ye Xiuqing also has a big head. If the food preservation problem is not solved, their family's business will be difficult to grow.

Is it necessary to develop franchise stores in every city like the chain stores of later generations? However, given their current business scale, there is really no way to save money to open a branch in a short period of time.

"Professor Lu, thank you for telling me this. Since the vacuum machine can only keep the food quality for such a short time, then I don't need it. I'm sorry, I didn't consider it thoroughly before, which caused you trouble."

Seeing Ye Xiuqing's squat expression, Professor Lu glanced at Professor Jiang, who was sitting next to him, and said to Ye Xiuqing.

"Actually, it is not impossible to keep the food quality for a long time."

"Really? Any way?"

Professor Lu pointed to Professor Jiang who was sitting there, but did not speak.

Seeing his movements, Ye Xiuqing was shocked. Then, he reacted immediately. Yes, why did she fall into a misunderstanding of thinking? The vacuum machine doesn't work, don't there still have preservatives?

Even in the era of the pursuit of zero addition and low zero corrosion in later generations. If you want to keep food for a long time, don't you also need to use preservatives?

"Professor Jiang? You are a professor in the Department of Chemistry? Can I ask you to contact a professor who can make preservatives for me?"

Seeing Ye Xiuqing look at her with bright eyes, Professor Jiang smiled and nodded at her.

"Okay, I know all about your situation, and there is no need to contact others anymore. I can solve this problem for you.

Of course, what you buy is food, and the requirements for preservatives are relatively strict. Don't worry, I still have a fertilizer project at this time. I took the time to make your preservative for you. I can give you the finished product in about a month. "

Ye Xiuqing was even more happy when she heard Professor Jiang's words.

"Professor Jiang, you have helped me a lot."

Having said that, Ye Xiuqing is also embarrassed.

"Then, if you need any materials or other things in the process of research, you can directly contact me and I will provide them."

Hearing what Ye Xiuqing said, Professor Jiang wanted to say no more. But seeing Ye Xiuqing's firm face, he hesitated for a while, and nodded after all.

Seeing Professor Jiang nodding, Ye Xiuqing couldn't help but smile more happily.

The thing she had been thinking about in her heart had been resolved. After chatting with the two professors for a while, she saw that Professor Lu seemed to have something to leave, so she said goodbye to them directly.

Rejecting Professor Jiang's plan to send her to the guest house, Ye Xiuqing returned to the guest house after leaving her mailing address.

She came back earlier, and the classmates who went out with the team leader have not yet come back.

Ye Xiuqing went back to her room first to plan how their business would go about after they had preservatives.

Thinking about it, she fell asleep. When I woke up again, it was night, and Li Xiaoxiao, who was out to play, was sitting in the room, ready to call her out for dinner.

Early the next morning, the team leader took their students back to the city. The leaders of each county brought the students from their own county back to the county, and this event was a complete success.

After returning to the county, Ye Xiuqing walked towards the yard they had bought before.

When she went to take the exam, Ye Jiangong was preparing to decorate the courtyard. I don't know how the decoration of the house has been in the past few days.

It was also a coincidence. She had just walked outside the gate of the yard and saw Ye Jiangong and Zhou Cuiyun who led Ye Yimin and rushed out of the yard.

"Qing girl, are you back?"

Seeing Ye Xiuqing, Ye Jiangong and Zhou Cuiyun were obviously very happy. Although she knew that she was only going to participate in the competition this time, and there was a teacher leading the team, there would be no problems.

However, when the child really appeared in front of her, Zhou Cuiyun still looked at it for herself before letting go.

"Just got out of the car, father, mother, what are you doing so eagerly?"

Hearing Ye Xiuqing's words, Ye Jiangong's expression suddenly became difficult to look at.

"Go back to the village, something happened to your fourth sister."
