Chapter 59: A Race Against Time

……

"Hurry up, hurry up, keep up!"

"Come on, take the skewers, good guy, you have a few skewers, don't flash your waist slowly!"

"Piwa, why are you still carrying the burden, you just need to greet everyone. ”

"Forget it, hurry up, don't pestle, you have to wait as soon as you stop. ”

……

The lychee harvesting season has finally arrived, and every household in Lijiagou has begun to enter a busy harvest period.

Lychee harvesting needs to be done at dusk and early in the morning, as it is cooler and suitable for lychee preservation.

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

Since the evening, the harvested lychees have been piled up on the dock one by one, waiting for Wuxi No. 1 to come back and carry them up.

Li Junge invited some strong guys from Lijiagou to wait on the edge of the dock, and everyone was waiting for the arrival of Wuxi No. 1.

Before this, Wang Qingguo and Uncle Wu had already maintained and inspected Wuxi No. 1 several times, and the engine was now in the best condition.

"It's coming, it's coming!" Looking at Wuxi No. 1, which was approaching, Li Junge stood among the people with a flat pole, feeling extremely excited.

The boat docked, and the fifth cousin pushed down two gangplanks, one on the top and one on the other.

And then there was the scene just now.

Every time he picks up a burden on the boat, the fifth cousin will hand the guy who picks the burden a stick, and the young man takes the sign and turns around and gets off the boat from another springboard, which will not delay the person on the boat, and finally takes the sign to find the father to settle the picker money.

A race against time has begun.

The lychee harvest season is in the middle of summer, and the temperature often reaches more than 30 degrees.

In addition, the lychee peel is thin and has a lot of juice, so it is very susceptible to mechanical damage such as bumps and microbial infection and cause rot.

At the same time, the peel of lychee is rich in polyphenol oxidase, peroxidase, which is the key enzyme for peel browning, usually placed at room temperature, and the ripe lychee shell will change color in less than 24 hours.

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

That's why there was a flying horse to transport lychees to Yang Guifei back then, and there was a scene of "riding the red dust and smiling".

By the way, the lychee eaten by Yang Guifei is Jiachuan lychee, if it really wants to be transported from Guangxi and Guangdong, it is simply unrealistic with the transportation conditions at that time, and when it is transported to Chang'an, it will be impossible to see it or eat it.

Later, people racked their brains and developed a number of lychee preservation technologies.

Lychee preservation technology is divided into color protection and preservation.

The color protection technology is generally to use a variety of lychee color protection agent to soak the lychee for a few minutes, and then use other preservation methods to keep it fresh after treatment, which can be kept fresh for three days more than the lychee without color protection treatment, and the color protection agent is generally made of citric acid and salt solution, and there are also special lychee color protection agents.

Although it only has three extra days of color protection, this is already a great improvement.

There are also many types of preservation techniques, the first of which is the liquid chemical preservation method.

Dissolving the drug in water and attaching it to the surface of lychee can form an invisible transparent film, which can not only effectively seal the stomata, reduce the breathing intensity, delay the senescence of the fruit, but also act as an adhesive to make it evenly distributed on the entire surface of the lychee, and play an antiseptic and sterilizing role.

Preservatives must have the characteristics of high efficiency, broad spectrum, low toxicity, low residue, and harmless to users and consumers.

At the same time, it should also be able to effectively prevent and control crown rot, black rot, pelange mold and anthracnose.

Soak the lychee for 1 minute, scoop it up, quickly dry it slightly with an electric fan, and then wrap it in non-toxic, breathable, and water-suitable plastic wrap as soon as possible.

The second is the solid-state preservative preservation method, that is, fumigation sulfur treatment, the principle is to use the sulfur dioxide gas produced by chemical agents to sterilize and bleach lychees.

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 effect on color protection.

Put the chemical packet and the lychee together in a sealed plastic bag, which will release sulphur dioxide and protect the lychee.

In recent years, inspired by the method of lychee transportation in the Tang Dynasty, people have invented the fresh-keeping bag preservation method.

In the Tang Dynasty, it was found that the lychee transportation was to be harvested and loaded into a fresh bamboo tube, stuffed with lychee leaves above the bamboo tube, and then completely sealed the opening of the bamboo tube with beeswax, and transported to Chang'an to open it again.

This method uses the principle that the quality of the fresh fruit can be maintained after the lychee is respirated in a sealed environment and forms a low-oxygen environment.

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

For all three methods, low temperature refrigeration is required.

A complete set of preservation process is adopted, that is, after color protection, liquid preservation or solid preservation, foam box ice cubes, special fresh-keeping bags outside the box, bamboo basket or wooden box protection outside the bag, plus the whole cold chain treatment, and finally can obtain an ideal preservation effect.

If the storage temperature can be maintained at four to six degrees, and the relative humidity is 75-90%, it can be kept fresh for one month, and the good fruit rate is guaranteed to be more than 85%;

The storage temperature is seven to eight degrees, which can be kept fresh for about 25 days;

The storage temperature is 9 to 12 degrees, and it can be kept fresh for about 3 weeks.

But the temperature is not as low as possible, below four degrees, the lychee will have irreversible freezing damage.

Therefore, from the lychee under the tree to the fruit bowl in the homes of thousands of residents, it is a race against time.

Seeing that the scattered fruits on Lijiagou's side were basically loaded, Li Junge jumped on the boat and shouted to the fifth cousin: "Fifth cousin, hurry up and start the boat, good guy, we are all in chaos here, Panao Township still doesn't know how long it will be delayed!"

Wuxi No. 1 immediately sailed off the shore to Panao Township.

When the boat arrived at Panao Township, it was nine o'clock in the evening, the lights on the small pier were bright, and Liang Huili had already led the team of villagers to wait anxiously there.

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

It was a two-piece slide.

The lychee is already boxed. After the bottom of the slipway reached the cabin, Liang Huili commanded two young men to get on the boat to guard, and the people on the shore began to carry boxes of lychees to the chute.

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

"Damn! Why didn't I think of it!" Li Junge slapped his head angrily beside Liang Huili: "We Li Jiagou know how to sell stupid strength!"

Liang Huili pursed her lips and smiled beside her, and said, "I saw that you were so confident, and I thought you were ready." These two slides are placed next to the lobby of the township government canteen, and you haven't noticed them after so many times?"

"Hey, I thought it was used when harvesting grain, Liang girl, you are not authentic, I picked the burden for a night. ”

"Hahaha, it's all your own fault for being too stupid, who else can you blame?"

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

Li Junge jumped on the boat, and he was still angry, this is really science and technology is the primary productive force!

He turned back to Liang Yatou and shouted: "Hurry up and get one for us over there, the good guy didn't tire me to death this night!

Wuxi No. 1 rushed to the county seat at full speed.

The dock is first, it is a rubber belt with a motor, after starting, put the lychee on the rubber belt, and the rubber belt will go up with the lychee.

Ermeng has already arranged a refrigerated truck, and a car will be sent out when it is full, which is all goods to Shudu fruit merchants, and the whole cold chain is carried out.

Li Junge jumped on the dock, and when he saw that it was Er Meng who commanded it personally, he immediately went over to smoke and said, "Brother Meng, I'm really embarrassed that I still have you to go out in person for this little business." ”

Er Meng didn't say anything polite to him, and said: "Isn't this the first time you've been on the set, I'm afraid you won't be able to turn away, come over and throw two whips, hahahahaha!"

Li Junge's black line in his head, most of these two fierce men are also from the township, so he likes to compare people to livestock.

Looking at the busy loading scene, I couldn't help but sigh with emotion: "Every snake bites, there is a doorway in every line, I have to learn more from you!"

Er Meng said: "It's okay, once born and twice cooked, I can do it as a dock worker, and you have no problem." ”

Li Junge told Er Meng about the slide in Panao Township, and then said: "I was educated on the first day, and I sold my stupid strength all night." ”

Ermeng laughed when he heard it.

Seeing that the last refrigerated truck was closed, Li Junge said to Er Meng: "Yes, I still have to deal with customers for the first time, and my sincerity must be shown." We'll see you later. ”

He also called the bean to explain to the second dog, and said: "That batch of loose fruits is wanted by the merchants of Manzhou, and you will also have to follow the car after loading, and meet the merchants, we will deal with them for a long time in the future." Learn more about the things on the dock from Brother Ermeng!"

Then he jumped on the refrigerated truck, waved his hand to Ermeng, and said, "Brother Meng, go back and invite the brothers to drink!"

All the way through the customs, to Manzhou on the expressway, Manzhou Expressway has opened a green channel to ensure that Jiachuan lychees can be transported out in time.

There was nothing to say all the way, and at four o'clock in the morning, the refrigerated truck arrived at the cold storage of the Shudu Agricultural Products Wholesale Market.

This wholesale market is more lively at night than during the day, and there are cars transporting agricultural products everywhere, which makes Li Junge, who is a road idiot, a little dizzy.

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

"Your Ministry of Transportation quickly takes over, you don't need to unload the car, this batch of lychee fruits is of good quality, you go directly to the East Railway Station, I will contact you there, and it will be sent to Beijing immediately!"

"Those who have just opened the box and inspected the goods, together with this car, will be pulled to the supermarkets immediately, and I will see the lychees on the shelves of the supermarkets at eight o'clock this morning!"
