A polymer-based spherical powder preparation device and preparation process are disclosed. The preparation device comprises a mill milling system and an inductively coupled plasma powder spheroidization system. The mill milling system of the preparation device can achieve ultra-fine grinding of the material at room temperature by applying strong extrusion, shear and circumferential stress to the material; and the inductively coupled plasma powder spheroidization system using high temperature plasma as high temperature heat source, the polymer powder can be heated uniformly, and the melting and cooling rate is fast, so the spheroidization can be completed in a short time. The preparation process of polymer based spherical powder was integrated and continuously produced by the preparation device.

The present disclosure discloses an appliance, suitable for home use, for grinding oil-containing hard produce, in particular oil-containing seeds, to therefore extract an oily substance product. For example, the appliance may grind sesame to obtain Tahini, or peanuts/almonds to obtain butter therefrom. The present disclosure further discloses a capsule to be received in a grinding appliance such as disclosed herein. The appliance incudes two grinding members, configured to grind the hard produce. Each grinding member has a grooved face that is patterned to be configured for grinding. The hard produce is grinded in the interface defined between the two grooved faces, defining a grinding zone. The grinding members typically have a shape of a circle and are aligned one with the other along a common axis. At least one of the grinding members is configured to rotate about the axis to perform the motion carrying out the grinding in the interface between the members. The hard produce is introduced into the grinding zone via one or more openings in at least one of the grinding members. The openings lead directly into the grinding zone, namely the hard produce that is fed through the openings reaches to a part of one of the grooved faces to initiate the grinding process. The grinding zone is constituted by two grinding portions, an inner grinding portion and a peripheral grinding portion, defining inner grinding zone and peripheral grinding zone, respectively. A peripheral collection zone is disposed peripheral to the peripheral grinding zone and is configured to collect the grinded oily substance product that radially flows from the peripheral grinding portions. The oily substance in the collection zone flows towards a substance collector, through which the oily substance flows for being collected.
