Convective rotary drum dryers are used for drying granular, loose and bulk materials. They can be used for drying salt, coffee, various powders, grain, nuts, seeds, fruit/vegetable bagasse, and many other products. When used in other industries, the dryer allows for the drying of salt, sand, expanded clay granules, and other similar non-flammable substances.

Convective rotary drum dryer for grain and spices

The product is introduced into the drying machine through a small hopper, where hot air is injected directly into the drum. The drying machine operates on a simple yet highly efficient principle. As the drum rotates, the product begins to swell inside it. The combined action of the airflow and the drum's rotation gradually dries the material. This dryer, utilizing a convective drying method, is specifically designed for drying bulk materials through the simultaneous effects of hot airflow and the drum's rotational movement.

Dryers are designed to dry bulk materials, they can be used for continuous operation.

When ordering a dryer, you can choose the heat source — it can be equipped with either an electric hot-air heater or a gas (LPG) heater. When selecting a heat source, it is important to note that the gas-heated version is not suitable for drying flammable or combustible products, as well as completely dry substances. In such cases, the materials being dried must have sufficient moisture content to prevent combustion. Additionally, the equipment and operating area for the dryer must be equipped with a fire extinguishing system.
