Description

Technical Field

[0001] This utility model relates to the field of spray drying technology, specifically a horizontal pressure spray drying device. Background Technology

[0002] Pressure spray drying is a technology that uses a high-pressure pump to atomize liquid materials into tiny droplets, which then come into contact with hot air to achieve rapid drying. Its core principle is to use high pressure (typically 70-200 atmospheres) to propel the material through an atomizer, forming mist-like particles with a diameter of 10-200 micrometers. These particles undergo efficient heat exchange with hot air inside the drying tower, causing rapid evaporation of moisture and ultimately yielding a powdered or granular dried product. However, current pressure spray drying devices suffer from inconvenient cleaning and maintenance of the inlet air filter. Over long-term use, impurities in the air easily accumulate on the filter surface, causing blockages and significantly reducing the ventilation efficiency of the air intake system, making filter cleaning difficult.
