With our innovative engineering capabilities MAAN ENERGY has been manufacturing and supplying Spray Dryers and granulators for more than 15 years in India.

The liquid food is generally preconcentrated by evaporation to economically reduce the water content. The concentrate is then introduced as a fine spray or mist into a tower or chamber with heated air. As the small droplets make intimate contact with the heated air, they flash off their moisture, become small particles, and drop to the bottom of the tower and are removed. The advantages of spray drying include a low heat and short time combination which leads to a better quality product. MAAN ENERGY is the leading Spray Dryer Manufacturer in India.

Spray dryers are widely used to manufacture homogeneous, free-flowing powders at a controlled particle size from a solution or suspension. Spray dryers are used in numerous gas cooling and liquid waste applications. MAAN ENERGY is a leading spray dryer manufacturer in India. Industries served to include chemicals, ceramics, catalysts, minerals, detergents, pigments, and salts. Product include large and small scale Spray Dryers, Spray Coolers, and high-pressure nozzles for Spray Drying. MAAN ENERGY is known for giving the best value in Spray Dryers with its combination of experience, quality, client service and competitive evaluation.

How does Spray Dryer Work?

Spray drying method employs a single process to convert a liquid solution/slurry into a powder.The liquid/slurry is atomized at high velocity, in a specially designed Drying Chamber, into a stream of hot air to evaporate the solvent. The dry powder is then separated from the air stream. We custom design Spray Dryers to suit the product quality, feed conditions, heating source available and the local environment norms.

Spray drying is a process of dehydrating fluids, solutions and thin slurries, into powder form. Liquid or slurry material to be dehydrated is sprayed in the form of a fine droplet dispersion into hot air stream. Both air and material either travel in parallel or counter flow. Drying in spray dryer occurs at very fast rate so that the contact of material to heat is not for longer time hence its does not damage the heat selectivity materials and becomes ideal for drying such materials.

Methods for Improvement of the Thermal Efficiency during Spray
Drying.

Working Principle of a Spray Dryer

• Material to be dried is sprayed / atomized in to the stream of drying medium (air).
• The water / solvent is evaporated and gets conveyed out by drying medium.
• The dried material is discharged out of spray dryer chamber in form of powder or granules.
• The drying medium is passed through a particulate separation equipment for fine particle separation.

The chamber design, spray pattern and the air flow distribution have a decisive influence on the final product characteristics. Therefore, MAAN ENERGY manufactures Spray Dryers that are highly efficient and produce high-quality dry powders.

Hot air inside the Spray Dryer chamber can be achieved by the means of direct firing of gas or by the means of fuels or uses of heat exchangers. Pressure spray heads, nozzles, and centrifugal atomizers are applied for distribution of the fluid elements. Processed product is separated by using cyclone separators in which the air is applied laterally at the top or settling chamber in which the direction of airflow is reversed to achieve separation of dried products by means of gravity.

Manufacturer & Supplier of Spray Dryers in India

We are the leading Spray Dryer Manufacturers in India. Spray drying Technology, which is mostly used to extract powder from the Liquid or slurry by applying Hot air on the sprayed Droplet of Slurry or Liquid. Due to the hot air, the water gets evaporated to form the feed and converted into powder. This is the preferred method of drying of many thermally-sensitive materials which are used in foods, pharmaceuticals, agro and much more.The spray dryers are co-current and counter current types.
