air cooler

1.Use scope & Characteristics

SKLN Series Counterflow Cooler adopts the convection between air

and materials and adopts the counterflow cooling theory to cool the hot and

wet pellets. Cooling air and materials touch with each other, converse and

vertically go through the material layer, gradually changing hot air and hot

materials touch with each other, through hot exchange, pellets will

be gradually cooled, hot air will be abstracted from the Cyclone

of fan which is on the top of cooler. It is able to avoid that cooling

air and hot material directly touch with each other and prevent that pellets will

be cooled so fast that cause the pellets to dehisce. This kind of cooler has the

following advantages of high cooling efficiency, high safety, long cooling time,

hot exchange completely, easy operation, etc. The temperature of pellets after cooling

is less than Room Temperature +3~5°C and the moisture content is less than 12 .5%.

2.Working Theory

The working theory of SKLN Counterflow Cooler is that the hot and wet pellets

which come from the Pellet Press enter into the cooler from the airlock on the

top of cooler and through taper type distributor equipment which can make

pellets to different top, bottom, left, right and middle parts enter in the cooler.

When Cooler starts to work, the pellets will be accumulated gradually. When

the position of pellets arrives to Level Detector, the brake motor will be connected

to start work. Driving by Reducer and eccentric mechanism,the Discharge Frame

move from left to right to discharge the materials. When the relative position between

Movement Discharge Frame and Fixed Frame reaches certain extent., the materials

will fall down and discharge from the gap between Movement Discharge Frame and

Fixed Frame. When the relative position between Movement Discharge Frame and

Fixed Frame are staggered, the materials will not be discharged. The materials will be

intermittent discharged during the process of cycled movement. When the quantity of

discharge is larger than feed-in, the pellets will reduce and leave the position of Level

Sensor, motor will stop work and the discharge will be end. When pellets touch the Level

Sensor, the motor will start to work and start a now discharge process which can

guarantee the continuous cooling production.Fan is always running during the whole

cooling process. The pellets in the cooler flow from top to bottom and the Air flows from

bottom to top. The above two flow positions are opposite which can form counterflow

cooling. Therefore, this Cooler belongs to counterflow type. The pellets will stay in the

cooler for some time, the natural air will enter into the coller from the bottom. It will make

heat exchange through the material’s layer in the body of Cooler. The fan will pump the

Air and take out of the heat and moisture.
