DIY coffee bean grinder: step-by-step instructions on how to make your own coffee bean grinder

Coffee is a must-have drink for many people every morning, and freshly ground coffee beans can bring a more intense and delicious taste. If you are someone who likes to try DIY projects, making a coffee bean grinder for yourself may become an interesting and challenging task. In this article, we will teach you step by step how to make a simple and practical coffee bean grinder at home.

Material preparation

First, we need to prepare the following materials:

• 1 electric whisk
• 1 empty jar (glass is best)
• 1 meat grinder blade (available at kitchenware stores)
• 2 metal mesh screens (available at hardware stores)
• 1 wooden or iron stick (for connecting the whisk and the blade)
• 1 wooden board (for the base)
• Screwdriver and screws

Step 1: Make the base

First, we need to make a stable base to support the coffee bean grinder. Using wooden boards and screws, fix two wooden boards together to form a T-shaped structure. Make sure this structure is strong enough and can withstand the vibration of the egg beater.

Step 2: Connect the whisk and blade

Next, we need to connect the egg beater to the meat grinder blade. First, insert a wooden or iron stick into the end of the egg beater and secure it with tape or a tie. Then, drill a few small holes in the meat grinder blade and use a metal wire to connect it to the stick on the egg beater.

Step 3: Install the metal mesh screen

Now, we need to install two metal mesh screens to filter the coffee grounds. First, cut a circular hole in the top of the empty can that fits the mesh screen. Then, place a metal mesh screen at the bottom of the hole and secure it with a screwdriver. Next, place the second metal mesh screen on top of the first screen and secure it with the screwdriver as well.

Step 4: Assemble the coffee bean grinder

Finally, we need to assemble the parts we made earlier. First, find a suitable position on the base, insert the egg beater into it and fix it with screws. Make sure the egg beater is tightly connected to the base and can rotate freely.

Next, cut a small hole in the top of the empty can and insert the whisk through the hole into the can. Make sure the whisk is aligned with the metal mesh screen.

Finally, close the lid of the empty jar and test the coffee bean grinder to see if it is working properly. Plug in the electric whisk and turn it on to see if the blades and metal mesh screen are operating smoothly.

Precautions for use

When using a homemade coffee bean grinder, it is important to keep in mind the following points:

1. Make sure the connection between the whisk and the blade is secure to avoid accidents.
2. Use the right amount of coffee beans and avoid grinding too many beans at one time to avoid damaging the machine.
3. Clean your coffee bean grinder regularly to keep it functioning properly and hygienic.

By making your own coffee bean grinder by DIY, you can not only enjoy the fresh and delicious taste of coffee, but also satisfy your pursuit of creativity and challenging projects. I hope the steps and precautions provided in this article can help you!
