Abstract: A cooling condenser system adapted especially for processing oily smoke and chemical evaporation includes a motor; a crank shaft to which are connected a number of compression pistons reciprocally operated in corresponding cylinders so as to deliver exhaust air to a cooling condenser; a plurality of exhaust inlet ducts each selectively communicating with a respective cylinder via a first check valve; a plurality of outlet ducts each selectively communicating with a respective cylinder via a second check valve that are led to openings of a cooling condenser and a pressure controlled valve in association with a filter screen disposed at the outlet of the cooling condenser through which the processed exhaust can be discharged to the surroundings. A hot/cold air generator is connected to the cooling condenser and can blow hot or cold air into the condenser and also send hot or cold air to the first and second check valves assembly. A number of collector pans collect the condensed products.

Abstract: A high pressure/vacuum operated apparatus for sewage and mud disposal includes a crossed duct having four terminals; and a movable tubular filter separably engaged with one terminal of the crossed duct with a flexible tube connected thereto; and an instant germicidal unit coupled to the flexible tube at one end and to a reservoir tank at the other which is associated with a vaccum pump and has an ultrasonic oscillator disposed therein for filtering heavy metal substance; and a reciprocally operated push stick which can detach the mud compressed into a solid block from the movable filter; a sewage discharge pipe connected to the upper terminal of the crossed duct via an inlet valve; one other terminal of the crossed duct being attached with a cylinder having a hydraulically operated piston reciprocally moved in the crossed duct, compressing the sewage mud against the movable tubular filter; a cleaning valve secured to the lower terminal; a filter plate made of high desity concrete or ceramics being secured to

Abstract: A reciprocally vacuumized and pressurized multipurpose food processing apparatus provided with a meshy basket in which all kinds of to-be-processed food can be received and that is plunged into the oil or other kinds of special fluid received in a frying pan for soakage or blanching especially applied to green vegetables or fruits; during the process a reciprocally applied pressure and vacuum are exerted thereto so as to make the soakage process faster and better; and in the meanwhile, the meshy basket can be moved in an up and down manner by a pneumatically operated cylinder and can be continually rotated in one direction for stirring purpose via a motor, making the soakage even. The soaked food is then fried with oil with the meshy basket moved up and down and turned continually under a vacuum state; afterward, the fried food is reciprocally subject to a pressure and vacuum state and de-oiled via a centrifuge.
