The experiment was successful.
When you put the small pieces of meat into pieces and shake the handle, the pieces of meat inside are crumbled into a ball, and finally the meat filling is discharged from the meat outlet like noodles.
There is no abnormal noise, no signs of jamming, the gear bite is tight, the blade is sharp and the angle layout is reasonable, and the blade can be guaranteed not to be entangled by the shredded meat filling when the meat is lowered.
Li Fengman was very satisfied, in this era when transportation was basically by walking and talking was basically by roaring, the old blacksmith was able to make this kind of simple strength of meat grinding machinery with only the iron-striking kung fu in his hands, and Li Fengman couldn't help but want to give him a few more praises.
"Very good!"
Li Fengman did not hesitate to praise himself, stretched out a thumbs up at Feng Cai, and said with a smile: "The master's craftsmanship is really not to say, it has completely exceeded my surprise, it seems that this time to create these things to find you, I really found the right person." ” Feng Cai bowed: "Li Gongzi has won the award, you are satisfied!"
” The apprentice behind him looked proud, and couldn't help but pout at Genfu, but unfortunately Genfu's attention had been attracted by the meat grinder, and he didn't receive his proud signal, which made the little apprentice couldn't help but be discouraged.
"Actually, before inviting Childe over, we had already made a preliminary attempt, and even wrapped a few bowls of wontons with ground meat filling to eat, which tasted quite good, no different from the fine meat filling cut and chopped out on the cutting board."
Feng Cai showed a relaxed smile on his face, and also stretched out his thumb to Li Fengman and praised: "The old man and these apprentices in the store, but they are all shocked by the whimsical design of Childe. ” "Although we deal with ironware all day long, we never thought that the meat filling can be made like this, and Li Gongzi's wonderful idea can be regarded as an eye-opener for me!"
Li Fengman laughed and took the old blacksmith's praise, "Actually, this old man is not as good as you say, I am just better at thinking than ordinary people." ” Li Fengman was interested and boasted: "In fact, this meat grinder, in addition to being used to grind out meat filling, can also directly process meat slices, shredded meat, and even meat mud foam as long as it is slightly improved." ” When Feng Cai heard this, his eyes suddenly lit up, "Is Childe's words true?"
” The old blacksmith seemed to see a bright business opportunity shining in front of him, and endless copper coins beckoned to him.
Once the meat grinder with many functions described in Li Fengman's mouth is processed, it will definitely be very favored by those raw meat shop owners.
With such a tool that can produce meat slices, shredded meat and meat foam in front of the store, it will definitely attract more customers.
"Of course!"
Li Fengman nodded affirmatively, and then changed his tone, "However, this is just a general direction, and it is up to you to figure out how to achieve these functions." ” Li Fengman is just a chef, and he is not a mechanical engineering background, so it is already a surprise to be able to remember the general structure of the manual meat grinder, but he really doesn't remember other things.
Feng Cai nodded in disobedience, and the passion that had just burned was half extinguished at once.
There is only a general direction, but there are no specific construction drawings, and the difficulty of making it is not ordinary.
However, being able to get so many functional concepts from Li Fengman's mouth can be regarded as an unexpected gain for Feng Cai.
Most great inventions often start with a small concept.
Why did no one ever think of grinding meat by machinery before Li Fengman?
Feng Cai couldn't think of it, the apprentices couldn't think of it, and the sages of the ancient past also didn't think of such a question, is it that they are not as smart as Li Fengman?
Obviously not, it's just that they're used to thinking the way they used to think, and they've never thought about it, and they've never thought of changing innovation.
This shows how important an idea, or an idea, is to anything.
The meat grinder was handed over to Genfu to play, and Li Fengman turned around and went to several other utensils.
Those knives were not unusual with ordinary iron pots, as long as a blacksmith with a little skill could make them, Li Fengman's main attention was still focused on the pressure cooker.
The function of a pressure cooker is mainly focused on the word high pressure.
The higher the air pressure in the pot, the boiling point of the water will also rise, when the temperature of the water reaches 100 degrees without boiling, the food can be cooked well, and some foods that need to be boiled for a long time, such as pork knuckles, stick bones and other ingredients, can become crispy and delicious in a very short time.
The high pressure is mainly focused on the sealing performance of the pot body.
The pressure cooker of later generations is generally used as a rubber ring as the sealing ring at the junction of the pot body and the lid, the rubber ring has a good thermal expansion and contraction performance, and the sealing performance is very good, its existence can ensure that the pot body will not have gas leakage when heating, and ensure that the air pressure in the pot can continue to rise.
And now in the Tang Dynasty of this era, there doesn't seem to be such a thing as rubber, so Li Fengman is very curious about what method the old blacksmith will use to solve the problem of sealing performance.
"Threads, of course!"
Feng Cai explained to Li Fengman in a fixed voice: "The soft and extremely strong material that Gongzi said has not been found for the time being, so Lao Yu thought that using a few more layers of threads might be able to solve the sealing problem that Gongzi said. ” As he spoke, Feng Cai reached out and picked up the pressure cooker he made and personally demonstrated for Li Fengman.
The walls of the iron pot are very thick, and in order to prevent high-pressure explosion, the old blacksmith deliberately thickened the thickness of the pot wall, which is about twice that of the ordinary iron pot, which also provides the possibility for him to polish the threads on the periphery of the pot body.
Circle after circle, in order to be safe, Feng Cai polished eight threads on the outer wall of the pot mouth, each of which was tightly fitted with the threads in the pot lid, so that even if there was no sealing of the rubber ring, the tightness of the air in the pot could be ensured.
After eight rounds, Feng Cai removed the lid from the pot body, and the corners of Li Fengman's mouth twitched, but he had to admire the old blacksmith's adaptability.
Although it will be a lot of trouble when loading and unloading the pot, at least it ensures its tightness and can basically achieve the performance of the pressure cooker.
In the absence of rubber, this is a rare workaround.
"Have you tried this?"
Li Fengman raised his hand and pointed to the pressure cooker that was dismantled by Feng Cai, and asked him softly.
Feng Cai shook his head and said no, although this pot was made by himself, but the shape of this pot is quite peculiar, and the usage is unknown, plus Li Fengman had warned them before that it would explode if they didn't use it well, so out of caution, this pot has never been tried after it was made.
"Alright, let's give it a try now!"
Li Fengman glanced at the surrounding environment, in the blacksmith shop, even in the product placement area, there are indispensable tools for striking iron, boilers, and clean water.
Li Fengman added half a pot of water to the pot, then put the two pieces of pork belly left over from the meat grinder just now, twisted the lid eight times and sealed it tightly, checked the outlet pipe, safety valve and pressure limiting valve on the lid of the pot, and after making sure that it was correct, he put the iron pressure cooker on the stove to burn.
