A tool for judging the internal quality of coffee.
Red light has a longer wavelength and can penetrate green coffee beans.
When the coffee beans are moldy or moth-eaten inside or inside, and the color is darker, the red light will be blocked, allowing you to quickly judge the internal quality of the coffee beans.
How to use?
1Wear red or yellow goggles.
Although red light has low energy and some people use it to repair cells, users who are photophobic are still advised to wear goggles.
2Shake to smooth the green coffee beans, and then adjust the brightness.
Let the green coffee beans be evenly distributed on the bean picking tray, and adjust the brightness from dark to bright. You can see the beans with external defects first, then the unripe beans, and then the beans with internal defects.
It is recommended that the beans picked out be divided into: 1. Defective beans, 2. Beans with the same brightness, 3. Beans with higher density that cannot transmit light at all.
3Pick out defective beans with tongs.
Use a pair of tongs to remove any defective beans. Don't let the defective beans ruin the flavor of the coffee.
Please spread the green coffee beans flatly on the bean tray, and then slowly increase the brightness.
The stones will be irregular and completely black, and the unripe beans and broken beans will be shiny.
As you turn up the brightness, the defective beans will gradually emerge.
An oval bean has irregular black color.
Although red light is used by manufacturers for photobiomodulation, it is called red light low energy light therapy.
But if you are photophobic, please wear red or yellow goggles.
Or use your tablet or phone's camera to look at the coffee beans for you.
The internal defects of the coffee beans are clearly visible.
