    Abstract: A system is disclosed which includes a chamber, one or more transmitters configured to emit EM radiation, one or more power harvesters, one or more EM stirrer, and a processing system configured to a) receive a measure of dimensional characteristics of the chamber b) control the one or more EM stirrers, c) evaluate statistical properties of the statistical EM environment, d) set a new criterion for acceptable statistical properties of the statistical EM environment, e) measure a lowest usable frequency of the chamber below which the statistical properties are not acceptable according to a predetermined criterion, f) determine an efficiency profile of the one or more power harvesters versus frequency, g) select an operating frequency that maximizes efficiencies of the one or more power harvesters, h) measure a collective efficiency of the chamber, and i) return to step d if the measured collective efficiency is below a predetermined efficiency threshold.

    Abstract: A method for forming a dissolvable freeze dried coffee is disclosed. The method may comprise the steps of freezing a liquid coffee concentrate and freeze drying the frozen liquid coffee concentrate until a hard outer crust is formed which may have a hardness greater than or equal to an interior portion of the freeze dried coffee.

    Abstract: A freeze vacuum drying apparatus includes: a spraying unit; a pipe unit; a heating unit; and a collection unit. The spraying unit sprays a raw material liquid into a vacuum chamber. The pipe unit has a non-linear shape, includes a first opening end and a second opening end, and traps frozen particles via the first opening end, the frozen particles being formed by self-freezing of liquid droplets formed by spraying the raw material liquid into the vacuum chamber. The heating unit heats the frozen particles in the pipe unit for sublimation drying, the frozen particles moving in the pipe unit from the first opening end toward the second opening end by kinetic energy produced during spraying. The collection unit collects dried particles that are formed by sublimation drying of the frozen particles in the pipe unit and released from the second opening end of the pipe unit.
