Kanadevia U.S.A. Ltd. (KVUSA) was established in 1979 in US as a subsidiary company of Kanadevia Corporation (KV), founded in 1881 in Osaka Japan, that is one of Japan`s largest industrial and engineering firm. Today KVUSA has supported the several industries for decades, delivering a wide variety of products, including precision machinery, spent fuel and waste storage/transportation casks and canisters, pressure vessels and shield tunnel boring machine in North America. In addition to these existing products, we will also bring water electrolysis and methanation system to the market near future, contributing to decarbonization and further industrial development in North America.

The video shows a cake discharge function of AUTOPAC-PRO Filter Press. The Plate Delivering Claws move the filter plates one by one, and the scraper peels off the cake on the surface of the filter cloth.

Slurry is supplied to chamber for filtration under 0.2 – 0.7MPa pressure (standard: 0.4MPa).Cake layer is gradually created in the chamber.
This layer can filtrate sub-micron particles which is smaller than filter cloth gap.Outcome filtrate volume becomes less as the pressure
in the chamber increases due to resistance of cake layer accumulated in the chamber. Filtration ends when it comes to set time, pressure or discharge volume of filtrate.

・Squeezing

Cake layer is compressed and squeezed by Diaphragm Sheet expanded with air (0.7MPa) or water (1.5 / 2.0MPa).After squeezing, cake layer is dehydrated and moisture is lesser. Also, remaining filtrate can be separated and collected.

・Cake washing

Washing agent is supplied to chamber to wash cake layer, causing Extract of ingredients and purify cakes

There are two method to wash cake.

1. Washing agent is supplied from slurry feeding inlets (Feed Washing Method).
2. Washing agent is supplied from outlet of filtrate and flow through cake layer to discharge at other bottom corner (Back Washing Method)
