What is a Drum Dryer?

ENCON Drum Evaporators are designed for dewatering concentrated slurries and sludge to a dry landfillable condition. These systems are electrically heated, operate in batch mode, and are controlled on a time and temperature basis.

Features

drum dryer - feature 1

High torque/low speed mixing system

A powerful high torque motor and gear reducer combined with a 316ss agitator provide gentle and consistent agitation even as the solution becomes viscous and solid.
drum dryer - feature 2

Pneumatic Lifting System

Pneumatic lifting system allows easy removal of lid and agitator system at the completion of drying. Mechanical safety latch and microswitch interlock switch provides safe and reliable operation.
drum dryer - feature 3

Simple to operate

First reduce wastewater to a concentrated slurry or sludge in standard drum evaporator mode. Then operate in dryer mode to dewater the concentrated slurry or sludge to a dry condition.
drum dryer - feature 4

Concentrate, dry, & dispose of residue in one drum

Using a 55-gallon steel drum as the process vessel minimizes both handling and time consuming cleaning.

Process Description

drum dryer - step 1

Step 1

Place a 55 gallon open top drum onto the drum dolly. Transfer sludge or slurry into the drum. Do not fill beyond 8 inches from top of drum. With the Dryer clamshell walls in the full open position and lid/mixer assembly in raised position, roll the drum into evaporator.

Wrap the rope gasket around the drum so that a positive seal will be made when the clamshell walls are closed.
drum dryer - step 2

Step 2

Close the clamshell walls and secure with the latching handles. Lower the pneumatically controlled lid and secure lid to clamshell walls with latching handles.
drum dryer - step 3

Step 3

Connect Drum Dryer stack to the flexible section of the permanent exhaust stack with quick connect/disconnect fitting.
drum dryer - step 4

Step 4

Turn the main power selector switch located on control panel to ON position. Turn green selector switch located on dryer panel (Dryer Mode) to ON postion. Set cycle timer on dryer panel to preferred setting. (NOTE: We recommend no more than 8 hours on first cycle)

Your system will begin heating. The lower batch of heating elements will turn on and off according to a factory set control temperature.
drum dryer - step 5

Step 5

A visual inspection of inside of drum should be made periodically through inspection lid to ensure sludge or slurry is not becoming excessively dry.

The heating elements will turn off when the cycle timer counts down to zero indicating completion of the drying cycle. (NOTE: System can be restarted by resetting cycle timer if residue is not adequately dry).
drum dryer - step 6

Step 6

Upon completion of drying cycle, turn Dryer Mode selector switch to off position. Unlatch handles of lid/mixer assembly from clamshell walls. Raise lid/mixer assembly by switching toggle switch on pneumatic actuator. Connect 2 mechanical safety latches (attached to blue frame) to lid/mixer assembly.
drum dryer - step 7

Step 7

Unlatch handles on clamshell wall seam to allow for opening of walls. Roll dolly with dried contents out of Dryer clamshell. Remove dried solids from process drum and into disposal drum.

Return process drum to dolly and fill with sludge or slurry to begin next batch.
