Seeing that Kong Wanxiang was pointing to the electric mill he had bought before, Xu Yi nodded with a smile and admired: "Boss Kong has a really good memory. ”

"After the prize, I compared the two machines myself, and the rice noodles ground by this machine are much finer than the other, and the speed of this machine is low, only more than 20 laps a minute. The rice noodles will not heat up during the processing process, unlike the rice noodles ground by the machine, which are hot to the touch, and may even burn off if they stick to the machine for a long time. As he spoke, Kong Wanxiang opened the bag inside the box, revealing a stone mill inside.

The cyan stone mill in the box, which is almost forty centimeters in diameter, looks one size bigger than his own stone mill, except for the fine polishing, I don't see anything too special.

Xu Yi stretched out his hand and knocked on the stone mill, and said with some doubts: "Boss Kong, this machine seems to be quite ordinary. ”

"Hehe, what can be seen in this way, this machine is divided into two boxes, there is only a stone mill here, and the bracket and power mechanism below are not in it. This machine is very heavy, my waist has just twisted a little bit of strength, you help me take a hand, let's lift the grinding fan out to see. ”

Xu Yi said with a smile: "Boss Kong, don't do it, I'll do it." ”

As he spoke, Xu Yi directly bent down and reached in from the two side corners of the box, directly reached under the bottom and grabbed the chassis of the stone mill to lift it out of the box, and then carefully placed it on the ground next to him.

Kong Wanxiang just wanted to say something, but seeing that Xu Yi had easily got things done, he couldn't help but give Xu Yi a thumbs up. "I'll go. You're awesome, boy. Originally, I wanted to move the upper fan of this grinding disc out. You've moved the whole stone mill out!"

"Ahh I thought you meant to move the entire stone mill out, so it's okay to take it out, right?" Xu Yi scratched his head, but he didn't understand the spirit.

But come to think of it, this stone mill is almost half a meter high when placed on the ground. Speaking of this stone grinding material, it is quite solid, the grinding fan on the top is almost nearly a foot thick, and the lower fan is not so thick, but it is connected to a grinding table with a diameter of more than 60 centimeters, I am afraid that it is not much lighter than the upper fan.

Kong Wanxiang reached out and touched the grinding plate. Raised his head and asked Xu Yi with a smile, "Do you know how heavy this stone mill is?"

"I think it's almost more than two hundred pounds, right?" Xu Yi shook his head and deliberately said something higher. If it is calculated according to his feelings, this stone mill will be more than 100 catties at most.

"You're too good, let me tell you, this stone mill adds up to more than 400 catties, how did you move it!"

"Is it so heavy?" Xu Yi couldn't help but feel a little embarrassed when he heard this, no wonder this Kong Wanxiang saw that he had moved the stone mill out, and his mouth was so open that he could stuff an egg.

"This mill is made of granite, and this granite is almost 6,000 catties per cubic meter. You calculate the volume and weight of this thing. Do you say you can have more than 400 catties?" Kong Wanxiang was still shocked, looked up at Xu Yi and said with a smile: "You are really blind if you don't go to participate in the weightlifting competition!"

"Then it's okay to take out this machine, right?"

Kong Wanxiang waved his hand. "It's better and you can see it better. Kong Wanxiang squatted down, pointed to the two small holes on both sides of the grinding fan, and then said to Xu Yi. "There are two steel handles in the ground inside the box, you take them and stick them in them.

Although Xu Yi said that he could easily remove this grinding fan, in order to avoid attracting too much attention, he naturally did so.

Kong Wanxiang watched Xu Yi insert the handle in, and continued to guide him: "You lift the grinding fan vertically, and you can lift the grinding fan more than ten centimeters." ”

Then he dragged the empty box over, covered the lid, and said to Xu Yi: "You move it to this, turn it over and put it on top of the box, well, don't smash this box slowly." ”

"Do you see the difference between this grinding fan?" as he spoke, Kong Wanxiang removed the upper fan from a small stone mill next to him and put it on the box in turn.

The two grinding fans can be compared to see the obvious difference, the grinding fan that Xu Yi removed is a layer of white porcelain-like material, which is densely covered with three circles of fine grinding teeth, but only the middle layer is the fan-shaped grinding teeth of ordinary stone grinding, and the outer two circles are radial patterns. And the grinding fan that Kong Wanxiang removed was carved out under the grinding fan to grind the chamber and teeth.

"See, this layer of almost two centimeters thick under this mill is not a natural stone, this is made of four hundred mesh of high-purity white corundum, it is not as rough as the grinding teeth of this stone mill at all, and it feels a little coarse porcelain at most, so the speed of this stone grinding is not so fast - of course, compared to this, it is still a lot faster. Kong Wanxiang flicked the handmade stone mill next to him.

Xu Yi also reached out and touched it, indeed, the edge of the grinding teeth was much smoother than that kind of small stone grinding.

"The middle circle of this stone mill is not much different from the ordinary stone mill, and the most important thing is that the two finer grinding teeth on the outside are completely processed by laser precision engraving molds. The material itself is delicate, and the grinding teeth are fine and wear-resistant, which is the reason for the high precision of this stone grinding. Speaking of which, my family has been using it for more than half a year, and it is still no different from the new one. ”

Kong Wanxiang walked to the side, patted another slightly smaller wooden box next to him and said, "You can help me take out the things in here." ”

Xu Yi walked over, and after moving all the things inside, he saw that in addition to the funnel on which the materials were fed, there was a square cabinet that was almost half a meter high, with a steel shaft the thickness of a rolling pin exposed in the middle of the top, as well as an operating switch.

"This is the base, and inside is the mechanical power part. The machine is made of absolutely solid materials, and even the steel plates on this side are welded from two-millimeter-thick stainless steel plates, which are corrosion-resistant and easy to clean. ”

Kong Wanxiang pulled the handle to open the base, pointed to the things inside and said to Xu Yi: "This motor is an imported silent maintenance-free motor, and there is a gear gearbox on it, so the sound is very small when working." ”

"How big is the motor in here?" Xu Yi couldn't see the motor nameplate, so he turned his head and asked Kong Wanxiang.

Kong Wanxiang took out a sealed bag from the base, pointed to the list on it and said to Xu Yi: "Two thousand two hundred watts of single-phase motor." ”

Xu Yi nodded, this motor is much larger than his own water mill motor. "Is there any other advantage to that?"

"This machine is easy to operate, there is nothing to say, even if you haven't used it and read the manual, you can understand it. The rest is nothing more than the use of materials, these materials are all safe and non-toxic materials, even the middle shaft sleeve is made of food-grade stainless steel, and the rest of the special functions will be tested for you later. ”

As he spoke, Kong Wanxiang instructed Xu Yi to put the upper and lower machines together, and after turning on the power, he scooped over a bowl of rice, plugged the feeder into the feeding port on the grinding mountain, and turned on the power.

I saw that with the slight sound of the motor, the grinding fan on it slowly rotated, and it was really very quiet.

Seeing that there was broken rice coming out of the gap in the middle of the grinding fan, the boss smiled and said to Xu Yi: "Ordinary small stone mills can't adjust the gap between the two grinding fans, so there is no way to adjust the granularity of the processed flour, but this machine is not. ”

"Well, that's really the case, Xu Yi nodded. ”

"If this machine processes broken rice the size of millet grains, it will be no problem to process thirty or fifty catties in an hour. ”

"Can you process corn kernels?"

"No, although this machine says it can process corn, but I have tried it so inefficiently that it can go down a few corn kernels at a time. Moreover, a lot of corn husks will be mixed in the processed corn grits, and they have to be cleaned up. However, it is really no problem to add corn grits to grind corn flour, which is much more delicate than the corn flour bought. ”

"Oh. ”

The speed of the machine is slow, and the processing speed is even slower, so the boss turns off the machine and cleans up the broken rice on the grinding table. After restarting the machine, he took two small sieves, pulled a basin and then added the ground rice noodles to the sieve and sifted them. "This is a 100-mesh sieve, see, the broken rice on the sieve should not have been cleaned before. ”

Xu Yi nodded, pointed to another and asked, "What about this?"

"I want to see how much can be sifted out with this 500-mesh sieve. ”

As he spoke, Kong Wanxiang put all the rice noodles back into the machine and continued to grind them, trying to pass them through the sieve every time.

But after seven or eight times, he stopped the machine. After so many times, there was almost half of the rice noodles left on the sieve, and he took a 400-gauge sieve and sifted it, but there was nothing left on the sieve. "Look at the limit of this machine, maybe it will be better to go to the water mill, 500 mesh should not be too much of a problem, but I don't think anyone who has nothing to do is not necessary to process anything to the level of 500 mesh. ”

Xu Yi nodded, quite satisfied with this stone mill. Although the fineness of the processing has not reached the level of matcha, it seems that it is not necessary to process it to such a fine degree, if it can reach 200 mesh, it is not much thicker than the glutinous rice flour milled by the water mill, which definitely meets your needs.

"What do you think of this?"

"How much does this stone mill cost?"

"This stone grinding thing is good, and the price is definitely not cheap, I want six thousand to the outside world, you have to buy five thousand five for you, if you don't issue an invoice, four thousand nine will do?"

"Can it be cheaper?"

"I really can't, you get what you pay for. If you want to be cheap, I have such a large size other stone mill here, as long as 2,000 yuan, I will invoice you, or?" As he spoke, Kong Wanxiang pointed to a stone mill next to him that looked very ordinary, and asked Xu Yi.

Xu Yi also smiled and said, "Boss Kong, we are all familiar customers, you can let me a little." ”

"It's really not much profit, at most I'll give you these sieves, how about you, if not, you can take a look?" (to be continued......)
