Abstract: In order to provide a treatment apparatus that can efficiently perform microwave irradiation, a treatment apparatus includes: a vessel made of a microwave-reflecting material, and having a first end and an irradiation opening portion, which is an emitting portion of microwaves that are emitted into the vessel; a first filter located so as to partition the vessel, and configured to separate solids that are to be separated, from the contents of the vessel; and a first reflecting member located closer to the first end than the emitting portion is and so as to partition the vessel, and configured to allow at least the contents having passed through the first filter to pass through the first reflecting member, and to reflect microwaves.

Abstract: Provided are roasted cacao beans with high total polyphenol content and reduced bitterness and the like, and a method for roasting raw cacao beans. Roasted cacao beans are obtained by roasting raw cacao beans in a state in which the pressure has been reduced below atmospheric pressure by heating for a prescribed period using microwaves so that the bean surface temperature reaches a temperature in the range of 50-90° C. The microwave heating time is preferably in the range of five to ten minutes.

Abstract: A molding apparatus is provided that can appropriately mold a molding material to which microwaves have been applied using a mold. The molding apparatus includes: a mold including a first mold member and a second mold member that form a molding cavity, the first mold member including communication holes that bring the outside of the mold and the cavity into communication with each other; coaxial cables for transmitting microwaves, first ends of the coaxial cables being attached to the communication holes; and a microwave application unit for applying microwaves into the cavity via the coaxial cables, the microwave application unit being connected to second end portions of the coaxial cables.
