Abstract: A ceramic deep-frying device capable of withstanding high temperatures and releasing far-infrared energy is made by grinding and mixing mullite, spodumene, energy ceramic material, ball clay, and kaolin clay into clay blank; molding the blank into ceramic green body; and sintering the green body at 1250-1320° C. for 18-24 hours. The device is completely immersed in the oil in a deep-frying vessel while leaving a gap between the device and heating pipe in the vessel or the inner bottom wall of the vessel, for enabling the oil to circulate through the through holes in the device due to temperature difference in the oil, causing the energy ceramic material to release anions and far-infrared rays that decrease van der Waals forces between oil molecules, and hence split, the oil molecules, thereby extending the service life of the oil, shortening the deep-frying time required, and lowering the oil content of deep-fried food.

Abstract: A heat-transforming ceramic roasting cylinder and a coffee bean roaster using the same are provided. The ceramic roasting cylinder is made by grinding and mixing ball clay, kaolin clay, mullite, spodumene, and an energy ceramic material into a clay blank; molding the clay blank into ceramic green bodies; and sintering the ceramic green bodies at 1250˜1320° C. for 18˜24 hours. The ceramic roasting cylinder has an internal roasting space where coffee beans are loaded. The ceramic roasting cylinder also has evenly distributed capillary pores through which heat can circulate to induce the energy ceramic material in the roasting cylinder to release negative ions and far-infrared rays. The far-infrared rays can reduce the van der Waals forces between the oil molecules in the coffee beans instantly, splitting large oil molecules into smaller ones, ensuring the oil in the beans are released sufficiently, evenly, and rapidly to the vicinity of the bean surface.
