Process dryers are employed to eliminate liquids or moisture from bulk solids, powders, parts, continuous sheets, gases, or other fluids. The incorporation of water, solvents, and other fluids is crucial to the processing and manufacturing of various industries such as food, pharmaceuticals, paper, construction, and automotive. However, before the final product is shipped, all process water and solvents must be extracted.

For certain products like food, paint, cement, plaster, etc., the water content is reduced to facilitate transportation, storage, and weight management. The water is then reintroduced to make the product consumable. Dryers play a pivotal role in the production of these goods. It is essential to optimise the dryer type and configuration based on the materials and processes involved in order to maximise product throughput and quality.

Different industries have different requirements and standards for drying equipment. Some of the common applications of dryers are:

Mining: Air dryers are essential for the mining industry, where the presence of water can cause corrosion, damage, and inefficiency in the equipment and processes. Air dryers can also improve the quality and safety of the products and materials that are mined or processed.

Aluminium: Air dryers play a crucial role in aluminium smelting. The purpose of air dryers is to remove moisture and other volatile components from the aluminium, ensuring it is ready for further processing. By effectively drying the aluminium, air dryers help maintain the quality and integrity of the metal during subsequent stages of smelting and refining.

Food and Pharma: These industries need dryers that are made of sterilizable materials and designed for hygienic purposes. The dryers must comply with the regulations and certifications of organizations like USDA or FDA. The dryers can handle liquid, solid, or liquid-solid mixtures of food products or pharmaceuticals.

Material Processing: These industries use dryers for processing metals and minerals. The dryers are used for drying ores, extraction products, metal sheets, metal powders, metal castings, slags, or scrap metal. The dryers can also dry binders that form and hold together agglomerates.

Paper and Textiles: These industries use dryers for drying cellulose, cotton, or pulp for making paper or cloth. The dryers use large heated rolls or cylinders to remove water from sheet products. The dryers can also dry woven or non-woven fabrics of various materials.

Construction Materials: These industries use dryers for drying lumber, wood products, wood chips, or wood boards. The dryers are also used for post processing of wood products into engineered wood, particle board, or plywood. The dryers can speed up the curing of paint and joint compound on the job site.

Manufacturing: These industries use dryers for drying adhesives or binders on surfaces or products. The dryers can use radiant heat or forced hot air to dry adhesive layers or coatings. The dryers can also dry plastics, elastomers, rubbers, or other polymers in different forms.

Semiconductor and Aerospace: These industries use dryers for removing any traces of water that may damage the components. The dryers are essential for preventing corrosion in precision bearings or other guidance mechanisms. The dryers are also used for drying wafers after etching and rinsing steps in semiconductor or electronic manufacturing.

Product Versions

There are different types of air dryers that are used in the mining industry, depending on the application and the required level of dryness. Some of the common types are:

Desiccant air dryers:These use a material that absorbs water from the air, such as silica gel, activated alumina, or molecular sieves. The desiccant is regenerated by heating or purging with dry air. Desiccant air dryers can achieve very low dew points, down to -70°C or lower. They are used for drying instrument air, pneumatic controls, and pipeline applications.

Membrane air dryers: These use a semi-permeable membrane that allows water vapor to pass through, while retaining the air or gas molecules. The water vapor is removed by a sweep gas or by the pressure difference across the membrane. Membrane air dryers can achieve dew points of -40°C or lower. They are used for drying oxygen and nitrogen generators, as well as low flow applications.

Refrigerated air dryers: These use a refrigeration system that cools the air to a temperature below its dew point, causing the water to condense and drain out. The air is then reheated to prevent condensation downstream. Refrigerated air dryers can achieve dew points of 2°C to 10°C. They are used for drying general purpose air, such as for tools, motors, and conveyors.
