4 ton/Day OKADA Continuous Sludge Dryer for Vape Liquid Manufacturer Plant

A Vape Liquid Manufacturing plant have a wastewater treatment system which generates a combination of 4 tons of Biological and Chemical Sludge per day. The sludge is dispose off to the local landfill. Our client was looking into a method to reduce the sludge weight before disposing it off as a cost reduction solution. Before the sludge enter the OKADA Sludge Dryer, it is first de-watered using a screw press. The moisture level after the screw press is recorded to be at approximately ~85%. The sludge is then channeled down into a hopper before entering a Shredder. The challenge of this sludge is that it contains high amount of oil in it due to the wastewater characteristics whereby the oil is remove in the Tilted Plate Interceptor and also via chemical treatment.

The Hot Air Generator function using the refrigerant heat pump produce hot dry air is circulated into the drying chamber. The system is a closed loop system thereby eliminate the needs for scrubber system. With such configuration, it also achieve energy efficient drying.

The Shredder is used to squeeze the sludge into a peanut like form so that more surface area for drying is created. This peanut formed sludge is then channeled through the dryer chamber by means of belt conveyor. The heat generated from the Hot Air Generator is conveyed through the ductings surrounding the Drying Chamber.
