Material: The potato press is made of food grade stainless steel, which meets the food grade hygiene standards available to the US Food and Drug Administration and is environmentally friendly and healthy. Three replacement discs include three interchangeable discs, a set of fine, medium, and coarse calibration discs with mesh sizes of 2.5mm, 5mm, and 12mm respectively. You can choose your favorite disc or combine it to accommodate various foods and achieve more possibilities. Large capacity saves you time and energy! The capacity of its press tank is 420ml, which can accommodate more potatoes than other small presses. You don't need to keep adding potatoes! Due to these two independently designed components, easy to clean cleaning becomes effortless. Just take apart your potato grinder, place it under the tap with a brush, clean up the never washed potato chunks, or throw them into the dishwasher! Widely used, it is the best choice for families, restaurants, and hotels, and also a good helper for making baby food. This is an excellent supplement to kitchen utensils.
