Patent number: 8282789Abstract: Extraction apparatus and method for obtaining essential oils, essence, and pigments from odorous raw materials (e.g., plant materials and Chinese medicinal herbs) by microwave radiation heating have 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. The extraction process can be performed without any preheating necessary.

Patent number: 7144473Abstract: The present invention relates to an evaporator for respirators, including a storage tank for a liquid, a gas intake flange and a gas outlet flange as well as an apparatus for heating the liquid, which is formed such that it can heat a small portion of the liquid and inject the formed vapor into the gas to be humidified, with the gas to be enriched with the liquid being passed through the upper part of the storage tank over the surface of the liquid, which may be located in the lower part of the storage tank, so as to provide a simple evaporator for respirators having a low consumption of energy. Moreover, the present invention relates to a method of evaporating liquids.Type: GrantFiled: June 15, 2004Date of Patent: December 5, 2006Inventor: Martin Baecke

Patent number: 7115186Abstract: A liquid material evaporation apparatus including a mixing chamber, a flow control unit, a first flow passage for introducing a liquid material, a second flow passage for introducing a carrier gas connected to the mixing chamber through a first nozzle, the first nozzle inhibiting backflow from the mixing chamber into the second flow passage. A third flow passage for discharging evaporated mixed gas is connected to the mixing chamber through a second nozzle, the mixed liquid material and carrier gas being forced through the second nozzle by the flow control unit, the mixed liquid material and carrier gas depressurizing after passing through the second nozzle to evaporate into a mixed gas in the third flow passage. Heat is applied to the mixing chamber and the second and third flow passages to enhance mixing in the mixing chamber and to avoid condensation in the third flow passage.Type: GrantFiled: March 11, 2003Date of Patent: October 3, 2006Assignee: STEC Inc.Inventors: Hideaki Miyamoto, Wataru Nishida, Tetsuo Shimizu

Publication number: 20040079491Abstract: A low temperature process for the dehydration and reconstitution of aqueous diluted glycol bearing deicing fluids using induced airflow (3a,3b,3c) and low temperature thermal sources (4a,4b,4c, 21a,21b,21c) to reduce the water concentration in aqueous diluted glycol bearing deicing fluids (22a,22b,22c). The invention employs the ability for air to vaporize water at low vapor pressures and temperatures in a direct contacting device (5a,5b,5c). The relative vapor pressure of glycol to water at low temperatures assures the preferential vaporization of water rather than glycol, thereby providing dehydration and effective reconstitution of the dilute fluids. The invention further defines a configuration wherein the degree of reconstitution accrues through a sequential series of contacting stages (5a, 5b, 5c). The effect is a net reduction of the glycol vapor pressure, thereby affording improved energy efficiency and reduced glycol carryover.Type: ApplicationFiled: October 28, 2002Publication date: April 29, 2004Inventors: James Jeffrey Harris, James William Harris

Publication number: 20040069414Abstract: An evaporation apparatus for solvent fuel comprises an evaporation tank containing the solvent fuel. A blower is installed on the top of the tank with its one end connected to an air inlet pipe, which has a blower switch associated with a check valve. The air inlet pipe is deeply extended to the bottom of the tank for introducing the air into the tank so as to evaporate the solvent fuel. The other end of the blower is connected to a pressure switch for controlling operation of the blower by detecting inner pressure of the tank. A constant temperature rod is provided nearby the bottom of the tank with its one end in connection with a temperature control switch to maintain the tank at a constant temperature. Besides, a scale graduation tube is provided for measuring the fuel quantity.Type: ApplicationFiled: October 9, 2002Publication date: April 15, 2004Inventors: Ta-Ming Chuang, Chih-Ping Lee

Patent number: 6716320Abstract: A liquid sample 3 held in an open container 2 and including a volatile solvent, is evaporated by continuously removing inert gas rich in vapor by means of a suction tube 5 whose open end is held close to the top surface of the liquid. Vapor in the gas is then extracted in a refrigerated condensing vessel 6, from where the purified gas is fed by a pump 7 for recirculation back into a sealed chamber 1 in which the container is mounted. In a modification, the inert gas is fed directly through a nozzle 17 into the container 2 wile the gas/vapor mixture is extracted from the chamber 1 for recirculation, after passing through a condenser 6 or the like.Type: GrantFiled: April 17, 2000Date of Patent: April 6, 2004Inventor: Michael Cole

Publication number: 20040060808Abstract: A solar still apparatus is described for the multi-effect distillation of a fluid such as water. A transparent condenser air duct overlies an evaporator air duct having a light-absorbing floor, both sharing a transparent plastic film wall. Air, blown by a fan, flows through the lower duct, where it progressively warms and evaporates a feedstock fluid. At the hot end of the lower duct, the air enters the upper duct where it flows in a reverse direction, progressively cooling and condensing its vapor, a portion of the heat of condensation being transferred through the shared wall to the lower duct. Thermal gradients established within the still facilitate the evaporation and condensation of the fluid with minimal heat loss to the environment and maximal recuperation of the heat of condensation for fluid evaporation. A working fluid may be used to extract useful power from the still's thermal gradients.Type: ApplicationFiled: August 4, 2003Publication date: April 1, 2004Inventor: Paul Alex LaViolette

Patent number: 6699369Abstract: A method for removing dissolved solids, particularly salts, from water. An apparatus for performing the inventive method is disclosed. The aqueous solution to be treated, for example sea water, is atomized using special non-pneumatic nozzles, and sprayed into an evaporation chamber through which air, heated by waste heat, is blown. The micro-droplets undergo rapid evaporation in the chamber, resulting in the separation of the salt solids from the vapor phase of the water. The mixture of suspended solids and water vapor is filtered to remove and collect the salts, and the water vapor is condensed to collect the salt-free water.Type: GrantFiled: August 10, 2001Date of Patent: March 2, 2004Assignee: Aquasonics InternationalInventors: William Francis Hartman, Larry Joe Kepley, Jerry Van Fox
