Abstract: An object is to provide a freeze-drying system and a freeze-drying method which can improve cleanliness and productivity. The present invention relates to a freeze-drying system in which freeze-drying is performed by sublimating moisture frozen by cooling an object. The system includes a cooling device (3) which generates cold with an air cycle in which air is used as a refrigerant, a freeze-drying chamber (2) accommodating a heat exchange unit which causes heat exchange between the refrigerant and the object, and a control unit (11) which controls a cooling capacity of the cooling device. The control unit adjusts the temperature in the freeze-drying chamber to a predetermined target temperature by controlling an amount of the cold generated in the cooling device.

Abstract: Microwave drying of ceramic honeycomb logs using a customizable cover that can take the form of a flexible wrap or a rigid cover is disclosed. The cover can be in the form of a wrap disposed directly in contact with the leading edge of the log surface. The cover can also be a rigid cover disposed adjacent but not in contact with the leading edge of the log surface. At least a portion of the trailing edge of the log can remain uncovered either by having windows in the wrap or by the rigid cover only covering the leading edge of the log surface. The customizable cover can be configured to compensate for log shape deformities as well as or in addition to the adverse effect on log shape cause by the drying differential created by passing a log through a microwave drying station leading-edge first.

Abstract: A complex type dryer includes a rotational cylinder, a drying material, a hot air provider, a hot air chamber and a scraping unit. The drying material provider is disposed over the rotational cylinder and coats a drying material on a surface of the rotational cylinder. The hot air provider is connected to both sides of the rotational cylinder, and includes first and second hot air tubes. The first and second hot air tubes alternately provide a hot air into the rotational cylinder or alternately exhaust the hot air passing through the rotational cylinder. The hot air chamber is disposed along an outer surface of the rotational cylinder outside of the rotational cylinder. The scraping unit is disposed at a side of the rotational cylinder, and removes the drying material from the surface of the rotational cylinder after dried by the rotational cylinder and the hot air chamber.

Abstract: The invention relates to a method for drying salts with a water of crystallisation content in convective apparatuses that can additionally be indirectly heated. The invention is primarily characterised in that the drying process takes place with a moisture content of the drying gas above a determined level. The gas surrounding the salt particles during the drying process therefore has a specific humidity. In this way, the rate of drying is positively influenced.

Abstract: The present invention relates to a control method for a laundry dryer. The laundry dryer is a heat-pump type laundry dryer and a compressor of the laundry dryer is a variable-frequency compressor. The control method includes setting a minimum running frequency of the compressor according to an amount of clothes to be dried, where the more the clothes are, the larger the set minimum running frequency is. Specifically, when laundry drying is started, the amount of the clothes being dried is detected. According to the detected information, a minimum running frequency of the compressor, corresponding to the information, is invoked, and the minimum running frequency of the compressor in the current laundry drying process is set.
