A dehydrating apparatus suitable for dehydrating food and other biomass products comprises a dehydrating chamber, a vacuum assembly, a magnetron assembly, an infrared heating assembly, a heated air circulation assembly, and a controller. The magnetron assembly is electromagnetically coupled to the dehydrating chamber and is operable to transmit microwave energy into the dehydrating chamber. The vacuum assembly is fluidly coupled to the dehydrating chamber and is operable to reduce the air pressure within the dehydrating chamber. The infrared heating assembly is thermally coupled to the dehydrating chamber and is operable to radiate infrared energy into the dehydrating chamber. The heated air circulation assembly is fluidly coupled to the dehydrating chamber and is operable to circulate heated air within the dehydrating chamber. The controller is communicative with and programmed to operate the magnetron assembly, vacuum assembly, infrared heating assembly and heated air circulation assembly to first reduce pressure within the chamber, then simultaneously transmit microwave energy, radiate infrared energy, and circulate heated air inside the dehydrating chamber upon specific dried product drying procedure.

A waste disposer comprising a primary dehydrating chamber, a grinding device, a secondary dehydrating chamber, and a storage chamber. The primary dehydrating chamber is adapted to allow waste to be heated therein to partly dehydrate the waste. The primary dehydrating chamber has: a first waste inlet for receiving the waste, a first vapor outlet for exhausting vapor from the waste, a drainage outlet for draining free liquid from the waste, and a first waste outlet for outputting the partly dehydrated waste. The grinding device is adapted to receive the waste from the first waste outlet and grind the waste to reduce the size thereof. The secondary dehydrating chamber is adapted to allow the ground waste to be heated therein to further dehydrate the waste. The secondary dehydrating chamber has a second waste inlet for receiving the ground waste, a second vapor outlet for exhausting vapor from the waste, and a second waste outlet for outputting the further dehydrated waste. The storage chamber is adapted to receive the waste from the second waste outlet and store the waste in the storage chamber.

Methods and apparatuses for drying electronic devices are disclosed. Embodiments include methods and apparatuses that heat and decrease pressure within the electronic device. Some embodiments increase and decrease pressure while adding heat energy, such as by using a heated platen in contact with the electronic device or by supplying a gas (e.g., air), which may be heated, into the interior of the electronic device.
