Hebei TianGuan Filter Press Co., Ltd.
An Food And Beverage Filter Press is a tool used in separation processes, specifically to separate solids and liquids. The process uses the principle of pressure drive,[clarification needed] as provided by a slurry pump. Among other uses, filter presses are utilized in marble factories in order to separate water from mud in order to reuse the water during the marble cutting process.
Concept Food And Beverage Filter press Technology
Generally, the slurry that will be separated is injected into the center of the press and each chamber of the press is filled. Optimal filling time will ensure the last chamber of the press is loaded before the mud in the first chamber begins to cake. As the chambers fill, pressure inside the system will increase due to the formation of thick sludge. Then, the liquid is strained through filter cloths by force using pressurized air, but the use of water could be more cost-efficient in certain cases, such as if water was re-used from a previous process.

The first form of filter press was invented in the United Kingdom in 1853, used in obtaining seed oil through the use of pressure cells. However, there were many disadvantages associated with them, such as high labour requirement and discontinuous process. Major developments in filter press technology started in the middle of 20th century. In Japan in 1958, Kenichiro Kurita and Seiichi Suwa succeeded in developing the world's first automatic horizontal-type filter press to improve the cake removal efficiency and moisture absorption. Nine years later, Kurita Company began developing flexible diaphragms to decrease moisture in filter cakes. The device enables optimisation of the automatic filtration cycle, cake compression, cake discharge and filter-cloth washing leading to the increment in opportunities for various industrial applications.
