Abstract: A modular grinding core includes a housing configured to be operatively installed in a variety of external grinding devices, a rasp support member having a coupling adapter configured to be operatively coupled to an actuation mechanism of a first external grinding device at a first time and to an actuation mechanism of a second external grinding device at a second time after being removed from the first external grinding device. The rasp support member includes a receptacle configured to removably receive any one of a variety of rasps. The rasp support member is configured to reciprocate in response a force exerted by the external grinding device. The modular grinding core further includes a grind block member resisting displacement of the food items or spices away from the rasp support member, and an adjustment mechanism allowing a user to adjust a gap between the grind block and rasp support members.

Abstract: Devices for extracting and filtering juice from fruit of various sizes and shapes are shown and described. In one particular embodiment, the device has an inner juicing cup, an outer juicing head, and a collection vessel. The inner juicing cup has an inner juicing head. The outer juicing head couples with the inner juicing cup. When coupled together, the outer juicing head encloses the inner juicing head. In addition, the collection vessel couples with the inner juicing cup. In another embodiment, the inner and outer juicing heads have teeth and blades, respectively, of varying degrees of sharpness. In another embodiment, the inner juicing cup has a drainage region for allowing juice to flow into the collection vessel, a first filtering region for filtering juice flowing from the heads to an external container, and a second filtering region for filtering juice flowing from the collection vessel to the external container.
