Chapter 59 Race against time
……

"Hurry up, hurry up, keep up!"

"Come on, take the sticks, good guy, you have a few sticks here, take it easy and don't lose your waist!"

"Pi Wa, why are you still taking on the burden? You just need to greet everyone."

"Forget it, let's go quickly, don't stick around, you have to wait after you stop."

……

The season of lychee harvesting has finally arrived, and every household in Lijiagou has entered a busy harvesting period.

Litchi harvesting needs to be at dusk and early morning, because the temperature is lower and it is suitable for lychee preservation.

During this period of time, except for the elderly and children at home, everyone's life has been completely reversed. In Li Junge's words, we are now living in American time.

Beginning in the evening, baskets of harvested lychees were piled up on the pier, and they were lifted up when Wuxi No. [-] came back.

Li Junge invited some strong guys from Lijiagou to wait by the pier. Everyone was waiting for the arrival of Wuxi No. [-].

Before this, Wang Qingguo and Uncle Wu had checked and maintained Wuxi No. [-] several times, and the turbine is now in the best condition.

"Here we come!" Looking at the approaching Wuxi No. [-], Li Junge stood among the crowd holding a pole, feeling extremely excited.

As the boat approached the pier, Uncle Wu pushed down the two gangplanks, one for the upper and the other for the lower.

Then came the scene just now.

Every time a burden is picked up on the boat, Uncle Wu will hand over a stick to the boy who carries the burden. After taking the stick, the young man turns around and disembarks from the other gangway, so as not to delay the people who board the boat, and finally takes the stick to find Dad settles the picking money in a unified way.

A race against time begins.

The litchi harvest season is in midsummer, and the temperature often reaches above [-] degrees.

Moreover, the lychee peel is thin and has a lot of juice, so it is very vulnerable to mechanical damage such as bumps and microbial infection and causes rot.

At the same time, lychee peels are rich in polyphenol oxidase and peroxidase, which are the key enzymes for the browning of the peel. Usually placed at room temperature, the ripe lychees harvested will change color in less than 24 hours.

Because of the above reasons, lychee is one of the most difficult fruits to keep fresh.

That's why there was a scene of using flying cavalry to deliver lychees to Concubine Yang, and the scene of "a concubine laughing on a ride".

By the way, the lychees that Concubine Yang ate were Jiachuan lychees. If it was really necessary to transport them from places like Guangxi and Guangdong, the transportation conditions at that time were simply unrealistic. By the time they were transported to Chang’an, they would have been unable to see or eat them. up.

Later, people racked their brains and developed a number of litchi preservation techniques.

Litchi fresh-keeping technology is divided into color protection and fresh-keeping.

Color protection technology generally uses various lychee color protection agents to soak lychees for a few minutes, and then use other fresh-keeping methods to preserve freshness after treatment. Compared with lychees without color protection treatment, lychees can be kept fresh for three days. The color protection agents are generally citric acid and salt It is prepared from a solution, and there is also a special lychee color protectant.

Although there are only three more days of color protection, this is already a remarkable improvement.

Fresh-keeping technology is also divided into multiple, the first is the liquid chemical agent fresh-keeping method.

Dissolving the drug in water and attaching it to the surface of litchi can form an invisible transparent film, which can not only effectively close the stomata, reduce the breathing intensity, delay the aging of the fruit, but also act as an adhesive to evenly distribute it on the entire litchi surface , and play antiseptic effect.

Preservatives must have the characteristics of high efficiency, broad spectrum, low toxicity, low residue, and no harm to users and consumers.

At the same time, it must be able to effectively control crown rot, black rot, green mold, and anthracnose.

Soak the lychee for 1 minute, pick it up, quickly dry it with an electric fan, and then pack it with a non-toxic, breathable, and water-resistant plastic wrap as soon as possible.

The second is the fresh-keeping method of solid-state preservatives, that is, sulfur fumigation treatment. The principle is to use sulfur dioxide gas produced by chemical agents to sterilize and bleach litchi.

This method can be used to inhibit pathogenic bacteria during long-term storage or long-distance transportation.The disadvantage is that the bleaching effect of sulfur dioxide has a certain impact on color protection.

Put the chemical agent package and the lychee into a sealed plastic bag, the agent package will release sulfur dioxide to protect the lychee.

In recent years, still inspired by the method of transporting lychees in the Tang Dynasty, people invented the fresh-keeping bag preservation method.

The transportation of lychees in the Tang Dynasty, after research, found that after harvesting, they were put into fresh large bamboo tubes, lychee leaves were stuffed on the top of the bamboo tubes, and then the openings of the bamboo tubes were completely sealed with beeswax, and the bamboo tubes were transported to Chang'an and opened again.

This method utilizes the principle that lychees can maintain the quality of fresh fruit after breathing in a sealed environment and forming a low-oxygen environment.

So people invented a special fresh-keeping bag, which is a plastic film composite heavy-duty packaging bag with a multi-layer structure, which can reflect more than 95% of the light, so that the temperature in the bag does not rise significantly under direct sunlight. It has excellent moisturizing performance, and can adjust the gas composition in the bag by itself, forming a low-oxygen and high-carbon dioxide storage environment, which can perfectly simulate the state inside the bamboo tube.

All three methods require low-temperature refrigeration.

A complete set of fresh-keeping process is adopted, that is, color protection, liquid fresh-keeping or solid-state fresh-keeping, ice cubes in foam boxes, special fresh-keeping bags outside the box, bamboo baskets or wooden crates outside the bag, and the whole process of cold chain treatment, and finally you can get Pretty good freshness preservation.

If the storage temperature can be maintained at 80.00°C to 80.00°C, and the relative humidity is [-]%, it can be kept fresh for one month, and the good fruit rate is guaranteed to be more than [-]%.
The storage temperature is seven to eight degrees, and it can be kept fresh for about 25 days;
The storage temperature is nine to twelve degrees, and it can be kept fresh for about three weeks.

But the temperature is not as low as possible. If it is lower than [-] degrees, irreversible freezing damage will occur to lychee.

Therefore, it is a race against time from the time when the lychees are dropped from the trees to the fruit bowls placed in the homes of thousands of households.

Seeing that the loose fruit on the Lijiagou side was almost finished, Li Junge jumped onto the boat and shouted to Uncle Wu, "Uncle Wu, hurry up and set sail, it's troublesome, our place is in such a mess, Pan'ao Township still doesn't You know how long it will take!"

Wuxi No. [-] immediately left the shore and headed for Pan'ao Township.

When the boat arrived in Pan'ao Township, it was nine o'clock in the evening, and the small pier was brightly lit. Liang Huili had already led a team of villagers and waited anxiously there.

Seeing the boat coming, Liang Huili directed the villagers to carry the two big guys.

Those are two slideways made of iron sheets.

The lychees are already boxed.The bottom of the chute extended to the cabin, Liang Huili commanded two young men to board the boat to guard, and the people on the shore began to move boxes of lychees onto the chute.

The cardboard box containing lychees slid into the cabin along the slide, and the two young men caught the cardboard box and placed it neatly in the cabin reserved for them by Li Junge.

"Damn! Why didn't I think of it!" Li Junge slapped his forehead angrily beside Liang Huili: "We in Lijiagou know how to be stupid!"

Liang Huili pursed her lips and said with a smile, "I see you are so confident, I thought you were ready. These two slides are placed next to the lobby of the township government cafeteria. You have gone in and out so many times and you haven't noticed?"

"Hi! I thought it was used for harvesting millet. Girl Liang, you are not authentic. You made me carry the burden all night."

"Hahaha, it's all your own stupidity to blame, who else can you blame?"

"Forget it, time is too tight, I have to leave immediately, and I will settle accounts with you when I come back!"

Li Junge jumped on the boat, still full of anger, this is really science and technology is the primary productive force!

Then he turned back and shouted to Liang Yatou: "Hurry up and get another one for us, I almost didn't die from exhaustion this night! I'm practicing silly boy!"

Wuxi No. [-] rushed to the county seat at full speed.

It is advanced on the pier. It is a rubber belt with a motor. After it is started, put the lychees on the rubber belt, and the rubber belt will carry the lychees up.

Er Meng had arranged for a refrigerated truck a long time ago, and when the truck was full, it would send out a truck. These were all the goods he wanted from the fruit merchants in Shudu, and the whole process was cold chained.

Li Junge jumped onto the pier, saw that Ermeng was personally in command, immediately went over to smoke, and said, "Brother Meng, I'm so embarrassed that I have to ask you to do it yourself for such a small business."

Er Meng didn't show any politeness to him, and said: "Isn't this the first time you've been used to pull the grinder, I'm afraid you won't be able to turn it away, so come over and throw two whips, hahahahaha!"

The black line on Li Junge's forehead, most of these two men came from the countryside, and they like to compare people to animals.

Looking at the busy loading scene, I couldn't help but sigh with emotion: "All snakes bite people, and there are skills in every line of work. I still have to learn more from you!"

Ermeng said: "It's okay, once you are a novice and second time you are an acquaintance, I can do it as a dock worker, and you are fine."

Li Junge told Ermeng about the slide in Pan'ao Township, and then said: "I've been educated on the first day, and I've sold my stupid strength all night."

Er Meng laughed out loud.

Seeing that the last refrigerated truck was closed, Li Junge said to Ermeng: "Yes, I have to take another bus. This is the first time I deal with customers, and I have to show my sincerity. Then we will see you later."

He also asked Qiaodou to explain to Ergou, and said: "The merchants in Manzhou want those loose fruits. After loading, you have to go with the car to meet the merchants. We will have a long-term relationship in the future. On the pier Learn more from Brother Ermeng!"

Then he jumped into the refrigerated truck, waved to Er Meng, and said, "Brother Meng, let the brothers drink later!"

Pass through the customs all the way, and get on the expressway in Manzhou. The Manzhou expressway has specially opened a green channel to ensure that Jiachuan lychees can be shipped out in time.

There was no words all the way, at four o'clock in the morning, the refrigerated truck arrived at the cold storage of the Shudu Agricultural Products Wholesale Market.

The wholesale market was busier at night than during the day, and there were trucks transporting agricultural products everywhere, which made the road-crazy Li Junge a little dizzy.

When I got out of the car, I saw a young woman in a professional suit directing there.

"Your transportation department hastened to take over. There is no need to unload the truck. This batch of lychees is of good quality. You go directly to the East Railway Station. I will contact you there and send BJ right away!"

"The ones that have just been unpacked for inspection, together with this car, will be taken to the supermarkets immediately. I will see the lychees in the supermarkets at eight o'clock this morning!"

　I finally got the signing done today, and it will be sent out tomorrow. It’s not easy. I blame Lao Zhou. The first upload was wrong, and the second ID card was too black... Hahaha I’m not ashamed to tell the editor that Lao Zhou is just like that black!Please continue to recommend!Lao Zhou will definitely work hard!
