[photo] third-generation star grain hand-pressed espresso machine evaluation can hand-press coffee machine also make coffee with grease

I heard my partner say that there is a small hand thickener on the market, and it is said that it can produce rich grease! Qianjie, which has always been full of the spirit of exploring new things, naturally wants to test this interesting machine.

So, the box prepared for the opening ceremony is very simple and beautiful. When you open the box, there is only a small hand-pressed coffee machine lying inside, and there is a small coffee spoon next to it, which is probably used to hold coffee powder.

Open the top cover and there is an obvious smell of plastic inside. It is recommended to wash it with hot water before drying it for a few days. This hand-pressed coffee machine is the third generation of Stargrain, which has a significant improvement over the previous two generations. for example, on the bracket, the shrink bracket is used to fit the coffee machine, saving space, and unfolding to support the whole coffee machine. and equipped with buckle, the bracket is very strong.

Study on disassembly structure if you want to understand its extraction principle, you must first learn to disassemble! There is also a component breakdown diagram on the official manual, which you can take a look at:

As in the picture above, basically all the parts can be disassembled.

On the top part is a syringe-like water pressure, which has a spring that can automatically reset after it is pressed down. the operation principle is like D special pressure. when the pressure bar goes up, it will pump water, and pressing down will spray the water out of it.

And the big cylindrical shape in the middle is the water tank, which is used to hold hot water.

When it comes to the water injection part, this water diversion network is a bit interesting, because the water injection is sprayed from the middle, and the middle part of the water distribution network happens to have no holes, which is the same as the design of the Italian coffee machine.

There is a pressure regulating valve under the cover, and according to officials, 15-20bar is free to regulate (doubtful). When disassembling, the rotating pressure regulating valve is actually adjusting the internal piston. When the piston is twisted to the tightest, the piston is wide open, and after loosening, the piston is semi-closed. Can it really produce grease? Try it right away. According to the official manual, the powder cup of this product can be filled with 18-22 grams of powder and the amount of water can be poured into 120-180ml. Then the first parameter used in Qianjie is to fill 18 grams of coffee powder and use 120ml for the amount of water. First of all, pour 18 grams of coffee powder into the powder cup, the coffee powder grinding directly use the store Italian coffee machine grinding thickness, like flour thickness.

Use a powder hammer to flatten the coffee powder. There is a MAX mark on the edge of the powder cup. Just don't exceed it.

After compaction, buckle it to the water tank and tighten it.

At this point, you can stand on the bracket and pour 120ml into boiling hot water. There is also a tick mark to look at.

Then install the upper cover, twist it tight, and begin to squeeze the compression bar and press continuously with frequency. Follow the recommendation of 1-2 seconds between every two presses, and the coffee liquid begins to appear at about 20 seconds.

It stops when the amount of liquid reaches 60ml, but it is surprising that such a small machine can press out grease, and it is very rich.

However, when tasting it, it is a little thin and bitter, and the fat indicates that it is white in the middle, which is probably too exquisite. So Qianjie decided to adjust the parameters again, the amount of powder continues to use 18 grams, hot water or put 120ml, the temperature is 95 degrees Celsius. This time, press directly to 40ml coffee liquid and stop.

This time the espresso is not bad in thickness and the oil is relatively more delicate. Then try making a hot latte. Ignore the details of how to hit the milk foam. Generally speaking, the oil is qualified, there is no caking or decomposition, and the atmospheric soaking water on the edge is a bit difficult to eliminate because it is concentrated into the coffee cup. And the pattern is also very comfortable.

This hand-pressed espresso machine is actually quite a surprise, especially at the moment when the golden coffee liquid is pressed out. If compared with the same type / price hand-pressed coffee machine or capsule machine, it is very competitive, its biggest feature is that it can choose a variety of coffee beans, the degree of freedom is better than the capsule machine, and the stability is similar to the semi-automatic coffee machine, mainly depends on the level of operation. On the other hand, the choice of grinding degree of coffee powder is the same as that of semi-automatic coffee machine.
