Cold chain for 20 years

Chapter 195 The ultimate temperature control

In addition to the medical freezer project of the provincial department, the Refrigeration Research Institute has only received a constant temperature and humidity cold storage project from a pharmaceutical company for more than half a year.The medical freezer is in the final stage of commissioning. This cold storage project is seamlessly connected. No matter how you look at it, the first year of the Refrigeration Research Institute has nothing to do with the food cold chain.

This cold storage project was introduced by Daye Group. Li Zhou wanted to customize the intelligent management and operating system for this enterprise. He learned about the establishment of the constant temperature and humidity storage project earlier, so he asked the Refrigeration Research Institute if he had any intentions.

Faced with such a big topic, people in the hospital agreed that it was impossible for Luan Pingxin to accept it. It had nothing to do with the cold chain of any system, but a cost-effective issue.It is no exaggeration to say that the pharmaceutical cold chain belongs to the top of the industry's pyramid. Compared with the pharmaceutical cold storage, the fruit and vegetable storage is undoubtedly extensive, and the pharmaceutical cold chain aggregates the sophisticated technologies of many industries.

The Refrigeration Research Institute is an enterprise, and everyone relies on business to make a living. The medical freezer has been delayed for half a year. I really want to build this constant temperature and humidity store. I don’t know how long these technicians will have to study hard for technical problems. .In people's eyes, getting involved in such a project has deviated from the original intention of the institute.

However, what surprised everyone was that Luan Pingxin not only took over this big project, but also dispatched a small number of people to follow up on the medical freezer, and the rest of the staff were all devoted to cold storage technology.And her request at the meeting made people even more stressed.

"Our goal is to control the temperature in the warehouse at 4.5-5.5°C throughout the year, and keep the humidity between 55%-65%. Our focus is first on the constant temperature and humidity unit that matches the enterprise, and secondly on the ethylene glycol The cold storage of the brine, and finally the specific numerical scheme of the air supply hole and the exhaust pipe.”

Luan Pingxin spoke in an orderly manner, but everyone felt dizzy when they heard it. The value she asked for was too exaggerated. Compare it with the values ​​stipulated by national regulations. The temperature is 2-8°C and the humidity is 45%-75%. The specified value of the constant temperature and humidity cold storage for medicines.

Only a temperature fluctuation of 1°C and a humidity change of 10% are allowed. This is undoubtedly the ultimate constant temperature and humidity storage. If it can be successful, it will definitely be the advanced level in the industry.

In essence, this topic is the difference in the cooling methods of refrigeration equipment. In the field of food cold storage, almost all of them use direct cooling, that is to say, the evaporator is used to directly deliver cold air to the storage. The cooling speed is fast and the system is relatively simple.

However, due to the particularity of the pharmaceutical industry and the differences in temperature and humidity across the country, anti-mildew, moisture-proof, anti-bacterial, anti-drying, and anti-static, the storage quality and safety of pharmaceuticals have always had extremely strict standards, so it cannot use simple direct cooling. Nor is it a means to achieve a constant temperature.

This must mention another cooling method of refrigeration equipment, that is, indirect cooling, which uses an intermediate medium to dissipate heat, and first cools the brine in the evaporator, such as brine and ethylene glycol, and then enters it in a water-cooled manner. cold storage.To make a metaphor, one is to hit someone with a fist, and the other is to touch with a palm, so as to achieve a real constant temperature, and the central air conditioner is also based on this principle.

You can imagine the time and energy invested here.

So, is it worth it?
The Refrigeration Research Institute not only violated the expectations of the market, but even the people inside felt that the road had gone astray.

All the technicians present were there. Looking at the silent scene, Luan Pingxin had no intention of explaining to the people, "I hope everyone will go all out for this project, and more importantly, they must be single-minded."

The words "one-hearted and single-minded" are a bit precious at this time. The Refrigeration Research Institute is not an independent cave, and voices from the outside world come in every day.Especially in recent days, words such as "Stuffy gourds that don't make money with cash" have emerged.

What is even more incomprehensible to people is that the powerful Byron Group has already proposed to continue to cooperate with the Refrigeration Research Institute on the Zhengyang project.Once this compressor project is successful, it will boost the Refrigeration Research Institute in an all-round way. Apart from other things, the terms of Byron's sole contribution and revenue sharing will not allow people to shake their heads at all.

But no one could guess what Director Luan was thinking. She seemed to be obsessed with making a medical refrigerator.

Of course, everyone can see her hard work, follow up on major and minor items, work in the equipment room in the middle of the night, and hold special meetings for subdivided teams. At most, she can conduct four technical discussions a day.

However, anyone who can change their thinking, contact Zhengyang and let the research institute enter the food cold chain market at the same time, based on the current situation that is everywhere, must be full of money.But she thinks about everything, but she doesn't want these things, so she stubbornly follows the cold chain of medicines, which is very similar to the famous saying "direction is more important than hard work".

But Luan Pingxin's temper, people have also experienced it, either sit down and concentrate on work, if you want to leave the pick, please let it go.People are very helpless, because as long as Luan Pingxin is in charge, the research and development can continue to advance. With her strength, no one has to do it.

After the meeting, the manager of the marketing department walked in again, and the materials in the folder were almost squeezed out.

But without saying a few words, the manager left again with familiar frustration.Regarding the meeting of the marketing department, this was already the fifth time he had heard "another day" within a month.

The word "market" is the irritability in Luan Pingxin's heart. If she is a bus driver, dozens of passengers in the back row are all calling grassland grassland, but she drives into a tunnel.

These were fine, but what she didn't expect was that Lao Luan, who was far away from Mozi, also had an opinion.

If he didn't make a good living of his fruit business, he drove to the research institute to scold his own girl.
