Super strong! Look at the coffee roaster modified by the popcorn machine.

Coffee is becoming more and more popular among ordinary people. It can not only be used as a drink, but also can effectively play a refreshing role and ensure work efficiency. But it is not so easy to get an authentic cup of coffee. First of all, the roasting of coffee beans is a problem. A netizen used the old popcorn machine at home to transform into a coffee bean dryer, and then used the coffee machine to extract coffee. Let's take a look.

The outer shell of the popcorn machine has been removed, leaving only the main part, that is, the coffee beans are cooked by strong hot air, and a heat-resistant brick is placed at the top, which is a little heavy and pressed down to prevent the beans from running out, and there are small holes to allow some small silver skins to float out.

On top of the heat-resistant brick, lock a thermometer removed from which side, look at it from another angle, and that's what it is as a whole!

Without saying much nonsense, let's get to the topic. Pick up the heat-resistant brick, and the space inside is the place to put corn. This experiment is to bake coffee, that is, to put coffee and raw beans.

Dig 2 to 3 tablespoons of raw beans with a spoon

Can not put too much, beans in the inside tumble not thoroughly, in addition to uneven baking will also crash oh!

The heat-resistant brick is used as a lid, covered, plugged in, and it starts to run.

As time goes by, the Fahrenheit temperature on the thermometer increases.

The temperature continued to increase, heating for about 10 minutes, and the first explosion was also heard.
