Depending on capacity, the dryer can be used as either a single or double rotary bundle dryer. the product trickles through the heated tube bundle, which turns inside of the dryer housing, and is heated up. heating medium and product do not come in direct contact.
Unlike a directheat dryer, in which the material is immersed directly into the heating media usually a hot gas stream and is dried by convection, a vacuum dryer is an indirectheat dryer. that is, the heat is transferred to the material as it contacts the dryers heated surface, drying the material by conduction.

Air dryer instruction manual 5 installation mounting 1. a dry, wellventilated area is the best location for installation of the dryer. it also should be in an area where the ambient temperature will not exceed 100176f 38c or fall below 34176 176f 1176c. 2. a flexible hose should be added between the dryer
Heated dryers heated dryers are similar to heatless dryers, with one big exception. dried air diverted from the system passes through a highefficiency external heater before entering the offline tower to regenerate the desiccant. because heated air holds considerably more moisture, this process reduces the amount of dry compressed air needed for

Based on the method of heat transfer, rotary dryers can be classified into directheated rotary dryer. indirect direct rotary dryer. indirect rotary dryer. special type. a rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids.
Direct heat dryers, where the heat transfer occurs by convection of hot air or gas inside a rotary cylinder, are the most common and used thermal dryers. hot air or gas flows through the cylinder and then transfers to the product, warming it and evaporating the water, therefore temperature of heating media inside the dryer is the mean parameter ...
So, the rotary dryer here mainly refers to singlecylinder and directheat rotary dryer. applied field rotary dryer is mainly used to dry materials of certain moisture or granularity in such areas as ore beneficiation, building materials, metallurgy, and chemical industry. the material granularity is generally not larger than 50 mm.
