Cold chain for 20 years

Chapter 273 The Power of Technology
Frost has always been a headache in the operation of cold storage. Low-temperature storage must be defrosted regularly, and high-temperature storage must be defrosted continuously. In this year, any cold chain enterprise must set up a department related to frost.

It's all caused by evaporative coolers, no matter what type of cooler, frost will form when it is below -[-] degrees.The increase of frosting will produce a frost layer. This frost layer is like wearing a coat during the cooling process. The evaporation temperature drops and the refrigerant circulation volume decreases, which will inevitably reduce the cooling efficiency.

Take the current meat processing workshop as an example. When a certain amount of frost has formed, it must be defrosted for six hours before reprocessing.When defrosting, the main engine needs to be shut down, which will inevitably lead to temperature rise. In order to quickly cool the main engine to the indoor temperature, it is necessary to activate the fan for subsequent cooling. The whole process is very cumbersome.

In Tongxing's meeting room, Luan Pingxin demonstrated the prepared courseware. First, he introduced the various shortcomings of traditional coolers, and then analyzed the market prospect of "automatic switching defrosting".

"The low-temperature storage of more than 30 degrees below zero is not within the scope of our research and development. We focus on defrosting instead of deicing. If our products can provide uninterrupted refrigeration power for the pre-cooling room in the chain park, first, it will solve the defrosting cost of the enterprise, cancel the defrosting device, and there will be no energy cost during the defrosting process.”

"Secondly, the regular shutdown and defrosting will cause large fluctuations in the temperature in the warehouse if it is small, and it is an interruption of the cold chain if it is large."

Luan Pingxin's remark is not a big deal, the reason why it is called a chain is that it is uninterrupted in essence.Strict cold chain from the field to the terminal, there should not be even a 1-minute interruption of temperature control, because these are temperature-sensitive products, which are prone to bacterial growth. For those who really do technology, "extremely easy" is equal to " at any time".

"Third, if the defrosting link is removed, the freshness of refrigerated vegetables and fruits will definitely be improved and the loss of dry consumption will be reduced. We will draw specific numerical conclusions through experiments later."

It was clearly a few words from the technical staff, but they made the people on the scene feel agitated.

In fact, when people hear about processing room and pre-cooling room, people have fully grasped its prospects. High temperature, low temperature, and ultra-low temperature are strictly speaking different categories of refrigeration technology.Among the three, the market prospect of high-temperature equipment around zero is the most promising.The reason is simple, because pre-cooling has the widest application and processing has the largest premium space, and it is an important part of many emerging cold chain parks.

If such a product can be launched on the market, it will be tantamount to being born out of nowhere. At that time, it will not be a question of how Tongxing will promote it, but a question of who to choose to cooperate with.Cooperating with a large industrial and trade group, the annual output starts at [-] units, which means a turnover of more than one billion yuan. Such a prediction is not an exaggeration. The equipment that can really meet the needs of large and small cold chain enterprises will make manufacturers swarm to.

Looking back, there are many people who want to start from this angle, but their confidence in this topic is not high.Moreover, unlike R&D centers in colleges and universities, R&D personnel in enterprises are most worried about stretching the battle line too long, worrying that it will cost a lot to mobilize many people, but the final result will be unsatisfactory, which will have a great impact on themselves. This is what all professionals look forward to.

But since Luan Pingxin can say this, he already has a set of working technical principles. In addition to research and development, there is also an equally important experimental stage. This link can only be used in a place like Tongxing.

"My idea is to divide the main body of the cooler into two independent parts, and the two parts allow air to enter at the same time, among which A provides cooling power and hangs frost, and B uses circulating air to defrost. Here The key technology is how to switch between A and B by adjusting the load operation."

"Our purpose is to turn the frost into humidity and return it to the air circulation by switching the cooler regularly, instead of accumulating more and more like traditional coolers. In simple terms, A's frost B melts, B's frost Jialaihua, when defrosting, the other party provides cooling, and the functions to be realized, you can refer to the inverter air conditioner."

This speech made the people present understand a lot, and at the same time jumped out of the previous thinking. "Slimming" and "subtraction" are buzzwords in many industries today, and "less is more" is regarded as a standard in many fields.

In terms of cold chain technology, people are also trying to lose weight, and light weight is regarded as a trend, so people only think about the realization of one cooler, and things like two coolers were not considered at the beginning.

But in Luan Pingxin's view, the function is the biggest. The first consideration of the cold chain is to do everything possible to do a good job of cooling. No one has ever taken an additional installation process as a standard.Of course, everything is based on data.

The next process will not be easy, not to mention the fruit and vegetable test after forming, the debugging of the product itself is a complicated process, but the future of this product is worth everyone's full dedication.It has to be admitted that it is very difficult for Tongxing people to do this. In terms of concrete equipment research and development, Tongxing is almost blank.

However, Qingyan Refrigeration not only came with a big frame, but most of the accompanying people were from the Department of Mechanical and Electrical Engineering of Longda, which also touched the hearts of many Ming students in Tongxing R&D Center, returning to the purely technical field with them, Fang Jue It is even more lining up with the word "research and development".

Throughout the whole process, Hu Shutong did not speak, mainly because Luan Pingxin's words completely left him no room for development.He originally thought that some things in terms of prospects might need to be supplemented, but it turned out that he is not a "technical nerd", and has a unique understanding of the various needs of the upstream and downstream of the cold chain in terms of equipment.

Tongxing's R&D center was started by Luan Pingxin at the beginning, and her shadow is everywhere in the subsequent series.Hu Shutong even felt that Luan Pingxin had already prepared a way for the R&D Center to survive technically.

In the past, we attracted talents and let people who are interested in technical equipment from major universities enter Tongxing. Loose orders continue to make a name for themselves.

But Tongxing can't just do things on paper, and can't just go forward for applause and appreciation. No matter everyone or a small family, they should assign themselves some real things.

She knows that he is a very stubborn person sometimes, but doing this has not changed the original intention of the R&D center. We are also working on front-line technology and benefiting the industry.So what is the difference between the description of vision planning and the creation of actual technical equipment?

This reminded Hu Shutong of the little sticky notes she had made when she was a child. She was doing what she said when she was a child. This meeting was for two teams, but it seemed to be saying——

However, it is time for us to realize.

Technology has the power of technology, and this is just the beginning.
