NYB
Product Overview
The NYB series high-efficiency plate-type enclosed filter is a precision clarifying filtration device that offers high efficiency, energy savings, and fully enclosed operation. It is widely used across industries such as chemical processing, oil & fat, petroleum, coatings, food, and pharmaceuticals. Featuring a uniquely designed structure, this product boasts a compact footprint, exceptional filtration efficiency, superior filtrate clarity, and fine particle retention—all while minimizing material loss. Importantly, it eliminates the need for consumables like filter paper, filter cloth, or filter cartridges, resulting in remarkably low filtration costs. Additionally, the equipment is easy to operate, maintain, and clean.
Main uses
● Oil and Fat Industry: Filtration of crude oil extracted by mechanical pressing, filtration of decolored oils, filtration of hydrogenated oils, and winterization filtration of fats, among others.
● Food industry: Decolorization and filtration of sugar syrups such as granulated sugar and glucose using activated carbon, as well as clarification filtration for beverages like beer, fruit juices, malt extracts, wine, and soft drinks.
● Chemical Industry: Crystalline separation in processes across petrochemicals, inorganic chemistry, and organic chemistry; filtration and separation of various catalysts; decolorization filtration using activated carbon, and more.
Key Features
● Compact structure with a small footprint;
● Good filtration performance, low loss, and excellent economic benefits;
● Mechanical slag removal features low labor intensity, ensures cleanliness and hygiene, provides a pleasant working environment, and minimizes pollution.
● High production efficiency—two units operating in parallel and alternating use enable continuous, closed-loop production.
How it works
During filtration, the pump draws the feed liquid through the inlet pipe into the tank, filling it completely. Driven by the pump, solid impurities are trapped on the filter mesh of the filter plate, forming a filter cake. Meanwhile, the clarified filtrate passes through the filter mesh, flows out via the outlet pipe, and exits the tank, resulting in a clean, clear liquid. As filtration progresses, more and more solid impurities accumulate on the filter mesh, causing the filter cake to thicken continuously. This, in turn, increases filtration resistance. When the pressure reaches a certain threshold, it becomes necessary to discharge the accumulated filter cake. At this point, stop feeding the raw liquid into the tank and instead introduce compressed air into the tank through the overflow pipe, pushing the remaining liquid from the tank into another leaf filter unit. Once the compressed air is turned off, if you're filtering decolorized oil or hydrogenated oil, steam is introduced into the tank to aid in the drying process. For other types of oils—such as crude oil—you can simply blow compressed air into the tank to help dry the filter cake thoroughly. After the cake has been fully dried, shut off the steam or air supply, open the butterfly valve, and activate the vibrator to gently shake the filter plate, dislodging the filter cake from the mesh.
