Drum dryer The different types of drum dryers vary in the method used for applying the wet material on the surface of the drum. Drum dryers are classified into two types, namely, single drum and double-drum dryers. Double-drum dryers consist of two drums rotating in opposite directions, with a narrow, adjustable gap between the two.

Some of the typical dry ing methods used for food products are sun d rying, tunnel dryer, spray drying, drum dryer, freeze-drying, microwave drying, and fluidized bed drying.

Drum dryers are used for drying sticky and highly viscous liquids and pastes. Drying temperature-sensitive items is done under vacuum, including proteins, vitamins, yeast, pigments, malt extracts, hormones, and antibiotics.

Rotary drum dryers are versatile industrial machines that play a crucial role in the drying process across various industries1. They are designed to efficiently remove moisture from different types of materials, ensuring optimal dryness levels. In this comprehensive article, we will delve into the basics of rotary drum dryers, explore their features, working mechanisms, …

The heatless desiccant dryer is the most expensive to operate as 15-20% of its rated flow capacity is consumed as purge air. The rotary drum dryer can lead to significant energy savings because of its unique design and controls. Even compared to a blower purge dryer, rotary drum dryers can save up to 50% of the lifecycle cost. Maintenance cost

In many drum dryers, the heat passes through the wall and reaches the mass of the contents, which is a critical step in the drying process. Studying the radial displacement of the material in the rotary drum dryer is important to better understand the phenomenon of heat transfer from the drum to the contents.

This feature dictates somewhat di erent operational characteristics by double-drum dryers than for single drum dryers, i.e., single drum dryers usually use higher drum rotating speeds (Gardner, 1971). Gardner (1971) presented a comprehensive review of a broad range of drum dryer operational characteristics for industrial applications.

Vacuum drum dryer Heat sensitive? Cool-running vacuum drum dryers and double drum dryers. Enables drying at low temperatures, thus avoiding damage to heat-sensitive product components. freedom from atmospheric contamination and independence from climatic conditions, operating results are always uniform. Moreover, these dryers

DOUBLE DRUM DRYER PRINCIPLES OF OPERATION : - GEM Double Drum Dryers convert molten liquid or pasty feeds into solid dried particles. Two identical drums are installed next to each other and the material is fed from the top into the gap between the drums. A thin layer of molten feed forms on the outside surface of the rotating drums.
