Mobile Industrial Drying Equipment For Drying Compound Fertilizer

Equipment Introduction

Automatic mobile industrial drying equipment is researched and developed on the basis of traditional

dryer to be aim at domestic and foreign customers’ requirement. The complete drying system is

installed on the movable trailer, which can be used immediately after simple commissioning once it gets

to the working site, and it occupies small area with short installation period. It is suitable for the working

condition of small-scale drying project, non-fixed working areas, with strong adaptive ability to the

working sites. PLC automatic control system can be adopted in the entire system, which contains

advanced testing equipment, thermometer, temperature control device, fault alarm and automatic

shutdown protection etc.

Working Princliple:

It is mixed flow dryer. The hot air as the heat medium is to bake food.

Its internal is mainly consisting of layers of staggered angular ventilation box. Outside the box is full of

grain which flows from top to bottom, the hot air enters by inlet box, up and down direction across the

grain layer, and exhaust through the exhaust box.

The hot air and grain flow cocurrent flow and reverse flow, called the mixed flow. When hot air pass

through the grain layer, heat and moisture transfer with food: hot air transfer heat to food grains, the

temperature rising, the moisture evaporates into the air and discharge as exhaust. Drying grains flow

downward to the tempering section, to make food grain of inside and outside layer temperature and

moisture balance, reach homogeneous precipitation. Food into the cooling section, after cooling the

food cooled to storage temperature and discharged.
