Chapter 205: Ultra-low temperature freezing
After its blood was released, Li Xiaofeng, Han Minghua, Li Xiaoliang and Li Xiaoming worked together to carry the big bluefin tuna, which was full of three or four hundred catties, to the freezer, and then spread the crushed ice evenly on its body until its whole body was covered with crushed ice.
However, this method of preservation is only used for a short period of time to maintain the freshness of the blue flag tuna, and it cannot be maintained for a long time.
Li Xiaofeng now feels more and more that there are more and more drawbacks in the use of this cold and fresh method of adding crushed ice on fishing boats.
First of all, they have to buy a lot of crushed ice almost every time they go to sea, which costs a lot of money every time, and this crushed ice will also increase the load of the fishing boat and increase the fuel consumption of the fishing boat.
Secondly, it is difficult to grasp how much ice to bring each time, it costs money and oil to bring more, and if you bring less, you are afraid that if you harvest a large amount of fish at that time, the crushed ice on the ship for preservation is not enough, and the fish harvested will rot and deteriorate.
And this kind of ice preservation method can actually keep fresh for a long time, generally up to 10-15 days, once this time is exceeded, it will seriously affect the freshness and taste of the fish caught on the boat, then these seafood will not be worth much!
In fact, fishing boats with a length of 30 meters and a displacement of more than 100 tons can already be qualified for pelagic fishing operations, but in fact, due to the supply of materials and the preservation of fish, such a large fishing vessel cannot operate independently in the open sea.
However, there is no solution, and sometimes many of these fishing vessels form a large fleet and work together in the open ocean.
The fleet will also be followed by specialized processing vessels and supply vessels to meet the needs of other fishing vessels in the fleet.
However, when Li Xiaofeng's new ship arrives, there will be no such trouble.
His new ship is equipped with seawater ice-making devices directly on it.
This is a machine that directly transforms seawater into a mixture of spherical ice crystals and liquids – ice slurry.
Because the ice slurry can flow, it can wrap the seafood in all directions, and can ensure that the seafood is not squeezed and scratched by hard ice cubes, and the original appearance of the seafood can be maintained to the greatest extent.
In addition, his new fishing boat is also equipped with an ultra-low temperature freezer, which can freeze the fish at minus 60 degrees Celsius, so as to maximize the freshness of some cherished fish, and even the fishing boat is specially equipped with two ultra-large ultra-low temperature freezers.
After the bluefin tuna was put away, Li Xiaofeng and his party came to the sorting cabin again to help sort the fish together.
It didn't take long for Li Xiaoming to shout at Li Xiaofeng, "Brother Feng, come and take a look, is this one the cigar Dharma shark you just mentioned?"
After Li Xiaofeng heard this, he walked quickly to Li Xiaoming, and saw that there was a fish more than half a meter long lying in the fish basket beside him, with a body that was far away, looking a little like a dog shark, but a little different.
The fish is now dying because it has been out of the water for so long.
After reading it, he nodded with a smile and said, "That's right, this is the Cigar Dharma Shark!" You'll freeze it alone in a moment."
"Okay, Brother Feng!" Li Xiaoming readily agreed.
The catch was more abundant and more varied, and they sorted it until almost twelve o'clock.
When the catch is sorted, their catch for the day is over.
After eating supper, they each went back to take a shower and go to sleep.
Early the next morning, Li and Xiaofeng got up and found that the weather was not good today, the whole sky was gloomy, and a heavy rain was about to fall, but fortunately, the wind on the sea was not strong today.
This kind of weather is not uncommon at sea.
After breakfast, Li Xiaofeng and his entourage gathered in the cockpit, which could be regarded as a simple morning meeting.
After discussing the matter, Li Xiaofeng specially said to Li Yongmin: "Third uncle, it is estimated that it will rain soon, you will remind the crew on the deck to pay attention to safety!"
Li Yongmin glanced at the dim sky outside, he estimated that the rain should not be small for a while, so it was also very solemn
Nodding.
After the meeting, everyone went back to their posts.
Li Xiaofeng also nodded and motioned for Han Minghua to start the fishing boat, and then with the roar of the machine, the fishing boat headed southeast.
Today, they plan to travel across the entire Diaoyutai Sea area to the vicinity of the Okinawa Trough on the east side of the Diaoyutai and then return to the port of Moss to end their trip to the Diaoyutai Sea.
Not long after the fishing boat sailed out, Li Xiaofeng informed Li Yongmin to arrange for the crew to drag the net into the sea before it rained.
Not long after the trawl was launched, a bolt of lightning streaked across the dim sky, and the rain poured down as expected amid lightning and thunder.
The visibility on the sea surface also dropped immediately, which made Han Minghua, who encountered this situation for the first time, a little scrambling. Of course, this is no surprise to Li Xiaofeng next to him, so he is calm and calm next to him.
Seeing Han Minghua's somewhat helpless appearance, Li Xiaofeng hurriedly comforted him and said, "Huazi, don't worry, it's normal to be nervous when you encounter such a situation for the first time! Now calm yourself down, turn on the emergency lights and searchlights on the fishing boat, and then notify all the crew to return to the cabin and close the hatch!"
Hearing Li Xiaofeng's words, Han Minghua suddenly had a backbone, and he quickly calmed down.
Then, as Li Xiaofeng said, he quickly turned on the emergency lights and searchlights on the fishing boat, and then quickly picked up the radio to inform all the crew members on the deck to return to the cabin immediately, and closed the hatch.
The crew members who were busy on the deck immediately put down their work and returned to the cabin to take shelter from the rain after receiving the notice.
After a while, Li Yonglin and Li Yongmin came to the cockpit wearing raincoats.
Looking at the heavier and heavier rain outside, both of them were somewhat worried that the fishing boat would be in danger in this situation.
Seeing the rain outside the window getting heavier and heavier, it was almost pitch black outside, as if it had suddenly re-entered the night.
Seeing this situation, Li Xiaofeng said to Han Minghua next to him, "Huazi, you have completed the task, now hand over the fishing boat to me!"
Hearing his words, Han Minghua quickly gave up the position of the bridge and wiped the sweat from his forehead.
Just a moment of hard work made him nervous and sweaty.
After Li Xiaofeng took over the fishing boat, he adjusted the direction a little and drove the fishing boat to continue towards the southeast sea.
In this way, the fishing boat drove for almost two hours in the torrential rain, and then the fishing boat sailed out of the range of the torrential rain as if through a rain curtain and came to a clear sea area.
