The present invention pertains in general to an apparatus and method for the drying and activating of infusing material, and the infusing, agitation and dispensation of oils in a controlled manner to produce a desired potency of an infusion while remaining below an identified maximum temperature threshold.

A pressure filter dewatering system and a method, which includes a pressure filter, an extrusion dewatering assembly, and a negative pressure dewatering assembly. The pressure filter includes a plurality of filter plates and filter cloth; a first chamber used for accommodating a solid medium to form a filter cake can be formed between adjacent filter plates; a liquid inlet hole allowing suspension liquid to enter the first chamber and a liquid outlet hole allowing filtrate to flow out of the first chamber are formed in each filter plate; each filter plate includes a core plate and two membranes respectively located on two sides of the core plate; a second chamber is formed between the core plate and each membrane; and a first channel and a second channel which communicate with the second chambers are arranged inside the core plate.

A method for filtering a precipitatable constituent from an extraction solution through a filter apparatus includes pre-cooling at least a portion of the filter apparatus to a reduced temperature that is effective to precipitate the constituent from the extraction solution. At least the cooled portion of the filter apparatus may be thermally conductive to act as a heat sink for the extraction solution being passed through the filter apparatus. The reduced temperature facilitates removal of the precipitatable constituent from the extraction solution.

Apparatuses and methods to rejuvenate spent filtration media are described. The apparatuses include a filtration unit to filter a liquid having solids that need to be removed and a rejuvenation unit to heat the spent filtration media that has reduced filtering capacity. The methods include using the apparatus to rejuvenate spent filtration media by removing solids deposited on the filtration media to allow its repeated reuse rather than being discarded and replaced with new filtration media.

A method of improving fuel efficiency in a diesel fuel internal combustion engine on a vehicle includes providing a combustion system including a fuel tank, an engine, and a fuel line disposed between the fuel tank and the engine. A heat exchanger is positioned on the fuel line between the fuel tank and the engine. Working thermal fluid is passed from a reservoir through the heat exchanger while fuel is passed through the heat exchanger, increasing the temperature of the fuel passing through the heat exchanger. A vibration isolation mount is installed between the heat exchanger and the vehicle, thereby reducing vibration of the heat exchanger during use of the vehicle. Heated fuel from the heat exchanger is delivered to the engine, improving the fuel efficiency of the engine by burning the heated fuel.

A molten metal filtration apparatus is provided. The apparatus includes a filter chamber having a floor, a metal inlet, a metal outlet, and a wall surface adapted to be partitioned by at least one filter element having an open cell structure characterized by a plurality of interconnected voids. The filter element partitions the filter chamber. At least one heater device is provided at an elevation within the filtration chamber that is equal to or below the filter element.
