MULTI-PURPOSE GRINDING - The multi-function electric grain grinder is ideal for daily use, grinding various DRIED/DEHYDRATED materials like beans, peppers, chili, coffee beans, grains, cereals, spices, herbs, and seasonings. Ensure materials are shelled and seedless. Do not grind nuts or materials with high water or oil content to avoid motor damage. PORTABLE SMALL SIZE, 200W MOTOR - Compact and lightweight electric spice grinder, easy to carry and store in cabinets or cupboards. The dry grain grinder may heat up slightly due to high motor speed. A slight burning smell during initial operation is normal. TRANSPARENT PLASTIC COVER - The transparent lid allows you to observe the grinding process. The mill produces coarse or fine powder. The 300ml grinding cup is made of stainless steel, heat resistant and durable. CLEAN & MAINTENANCE - The cover and cup are washable. Do not wash the grinding cup or motor base directly with water. Use a brush or dry cloth for cleaning. This electric grain grinder is not waterproof. Allow a 3-second rest after every 5 seconds of use to enhance motor performance and prevent overheating. Ingredients should cover the blade but not exceed 2/3 of the grinding cup capacity. ONE-BUTTON START, EASY TO USE - Press the ON/OFF button to start grinding, release to stop. Steps: Pour coffee beans into the grinder (up to 2/3 of the cup). Securely close the upper cover (must be tightly closed during use). Press and hold the button to start, pause every 5 seconds for 3 seconds. Turn off the power and pour out the ground material. The fineness depends on grinding time.
