Liquid Screening Technology

For the continuous separation of solids from liquids, AZO developed the liquid screener FLF 650. It is used to separate cheese fines from whey, butter from buttermilk, fruit remains from fruit juice or for safety screening in the production of latex, preliminary clarification of sewage water or wherever agglomerates may develop when stirring powder into liquids. Further, the liquid screener is utilized for the recovery of solids from liquids, for safety screening in the production of varnish, the separation of solid chemicals from sewage and finally removal of remains in used oil.

The general functional principle of the liquid screener is as following: The liquid with the solids is metered continuously and without bubbles into the screener via the inlet pipe. The rotor with the feeding screw transfers the liquid into the screening chamber where it is gently swirled through the screen fabric by the fluidizing bars. The liquid then flows through the screen fabric into a collecting vessel via the liquids discharge. The solids are conveyed to the solids outlet where they are discharged into a chute and transferred to the production process. The residence time in the screen chamber and thus the residual moisture of the solids can be influenced within certain limits by the adjustable tilt. The throughput capacity especially depends on the mesh size and the driving speed of the frequency converter (optional). The screen fabric can vibrate freely and thus cleans itself automatically. Blows caused by smaller foreign substances can also be get under control so that there is no damage.

The FLF 650 means best value for money with a very short amortization period. It can realize high throughputs even with with very fine mesh sizes. The liquid screeners are design for easy cleaning, dismantling is simple due to quick-release clamps. Further the screen element can be changed without tools.
