Abstract: A mixing container including an outer vessel, one or more inner vessels, and a lid. The outer vessel has a bottom, an open mouth and a peripheral sidewall between the open mouth and the bottom. The one or more inner vessels each have an end, an open mouth and a peripheral sidewall between the end and the open mouth. The lid is configured to be removably coupled to the open mouth of the outer vessel and the lid is characterized as having an outer surface and an inner surface coupled to the ends of the one or more inner vessels. A seal is formed between the open mouth of each one of the one or more inner vessels and the bottom of the outer vessel when the lid is coupled to the open mouth of the outer vessel.

Abstract: A multi-component mixing device comprising an outer container and an inner vessel. The outer container comprises a closed end, a mouth and a peripheral wall between said closed end and said mouth. The inner vessel is disposed within said outer container and the inner vessel comprises a top portion, a bottom portion and a peripheral side wall between said top portion and bottom portion. The peripheral side wall of the inner vessel is defined by first and second sections, which are slidably engaged to one another between a first position and a second position. In the first position, the inner vessel defines an enclosed cavity and in the second position, the inner vessel comprises a first opening corresponding to the enclosed cavity.

Abstract: The device fits over the outer surface of a beverage container at a first surface, and a structural member extends between the first surface and a second surface which contacts a second container stacked on the first. The structural member serves to support the separation between the inner surface of the second container and the outer surface of the first container. The related process involves the stacking of beverage containers one upon another employing one device between two containers to create stacks of containers.

Abstract: Method of pretreating citrus waste to break cell structure, pasteurize or sterilize citrus waste solids and remove inhibitory peel oil components (e.g., limonene) involving optionally reducing the particle size of the citrus waste prior to preheating, preheating the citrus waste through indirect heating in a preheater reactor to form preheated citrus waste and conveying the preheated citrus waste to a main reactor, heating the citrus waste through a combination of (simultaneous) indirect heating and direct heating to produce treated citrus waste solids that are pasteurized and a vapor containing water and peel oil components, separating the pasteurized citrus waste solids and the vapor containing water and peel oil components, and collecting the separated vapor containing water and peel oil components by condensation. The method optionally includes cooling the pasteurized citrus waste solids followed by saccharifying with enzymes and fermentation to produce ethanol or other products.
