Abstract: The invention relates to extraction apparatus and method for obtaining essential oils and essence and pigments from odorous raw materials by microwave radiation heating under sub-critical conditions, which has advantages of easy operation, higher extracting temperature and efficiency. The microwave chamber has a power level of 100 W to 1,500 W and its microwave radiation has a frequency at 915 MHz or 2,450 MHz.

Abstract: An apparatus such as a hand dryer is configured to expel air in the form of a heated flowstream and an unheated flowstream. The heated flowstream results from active heating, such as would occur when the apparatus exposes the air to a heating element. The heating element heats the air to a temperature that is greater than the air in the unheated flowstream.

The exit plane also defines a second side on which a target can reside. The heated flowstream can mix with the unheated flowstream on the second side, wherein mixing can occur when the heated flowstream and the unheated flowstream impinge on the target.

Abstract: For continuously drying a cloth, the cloth is subjected to a drying process in which high pressure dry hot air is jetted against the cloth in a zigzag pattern from both sides thereof while transporting the cloth continuously through a cloth passage. The cloth passage is a gap formed between a pair of horizontally extending parallel endless net conveyors located one above the other. In accordance with the rotation of the two conveyors the cloth is vigorously beat and vibrated as it passes through the gap in a snaky state under no tension to afford drying of the cloth. When the drying process is effected by stepwise lowering the temperature of the cloth, or is repeated by cooling the heated cloth in the open atmosphere, the drying resembles natural drying, preventing the cloth from becoming fragile, and moreover, in particular heat energy is saved. A cloth in a ropy state can also be dried satisfactorily and effectively by inserting a cloth untwisting process and a cloth expanding process prior to drying.
