A fluid extraction apparatus includes a first chamber within which waste material is configured to be disposed and a second chamber having a vacuum source interface. The first chamber may be in selective fluid communication with the second chamber. In various embodiments, the fluid extraction apparatus further includes an intermediate valve disposed on a conduit extending between the first chamber and the second chamber, wherein the intermediate valve is selectively actuatable to control the selective fluid communication. In various embodiments, the selective fluid communication between the first chamber and the second chamber is exclusively via the intermediate valve and the conduit.

The present invention discloses a method for freeze-drying drug liposomes powder assisted by a variable-frequency alternating-current electric field, which includes the following steps: (1) preparing a drug-liposome suspension sample; (2) dehydrating the sample under a 1-10 kHz, 3-10 kV high-voltage alternating current; (3) freezing and drying the sample treated in step (2) at 20 C. to 40 C., under a 10-25 kHz, 0.2-1 kV high-voltage alternating current, until completion of the freezing process; and (4) heating and drying the sample in a vacuum until completion of sublimation and desorption, and obtaining the drug liposomes freeze-dried powder. The present invention not only greatly shortens a freezing and drying time, but also controls a size of nuclei and ice crystals, further ensuring a quality of the freeze-dried powder.

A drying apparatus for a water damaged floor structure having an intermediate layer between a surface layer and a subfloor, which drying device comprises a suction blower for, from an outlet opening in the floor structure, drawing humidified process air from the intermediate layer and heating the humidified air, and a sorption dehumidifier to receive the heated process air from the suction blower, convert it to heated dry air and, through an inlet opening in the floor structure, separate from the outlet port, force the heated dry air to the intermediate layer, where the heated dry air accumulates moisture from the floor structure and is converted to new process air which is again sucked up and heated by the suction blower in a closed process. According to the invention, the dryer has a PTC element for a sorbent block in the dehumidifier, a common housing for the suction fan and dehumidifiers, and a sound and heat insulation in the housing.

A shoes care device includes an inner cabinet and a module housing. A blowing part, a heating part, and a dehumidifying part are jointly accommodated in a module chamber inside a module housing, and the module housing is detachably coupled to a lower side of the inner cabinet. A shoes care device having a structure in which condensed water generated while passing through the blowing part, the heating part, and/or the dehumidifying part can be prevented from being leaked, and it is advantageous for leakage management, and the module housing and a component accommodated therein are easily managed and replaced.

A method of drying sticks, a related apparatus, resultant product and its uses where the method involves presenting a plurality of sticks in parallel as a single layer, pressing each stick with a bank of pressing members on and/or into at least one face of the sticks, each with plurality of protuberances, thereby to constrain the sticks against crook, and drying the sticks when so constrained. Preferably each bank of pressing members is an underside of a frame or lattice of a stack of such frames or lattices able to receive such a single layer of sticks between adjacent overlying/underlying frames or lattices, the protuberances preferably being only downwardly directed.

The present invention relates to the field of heat treatment of a product to be dehydrated, such as sludge from a waste water treatment process. The present invention relates more particularly to a method and to a facility for drying such a product, making it possible to implement a hydrothermal carbonization operation on reactor 1 followed by a filtering and drying operation, preferably on a heating filter press 6. In order to dry said product in the heating filter press 6, a heat-transfer fluid from a heat exchanger 2 is made to flow in said heating filter press. The heat exchanger 2 is arranged so as to transfer, to the heat-transfer fluid, at least some of the heat contained in the product to be dehydrated that is output from the reactor 1.

A drying machine includes a clothes holding unit for holding clothes therein, a drying passage including a heater to supply heated air to the clothes holding unit, a dehumidification passage for removing moisture from the air exhausted from the clothes holding unit to supply dehumidified air to the drying passage, a circulation fan provided in the drying passage or the dehumidification passage to circulate air, a moisture absorption unit for absorbing moisture from the air exhausted from the clothes holding unit, a renewable passage for supplying the heat absorbed by the dehumidified passage to the moisture absorption unit to renew the moisture absorption unit, and a controller for controlling the circulation fan to circulate the air exhausted from the clothes holding unit for a preset time period.

The present invention provides methods and systems for processing raw wood fiber to stabilize the shape and dimensions of the wood produced from the raw wood fiber following processing, by heating the raw wood fiber in a substantially oxygen-free atmosphere with combustion gas and super heated steam. The combustion gas is generated by burning a wood fiber-based fuel.
