Fast & Efficient Drying

Continuously Process

    Classification by Spray Method

    Spray dryer is a one-step direct drying method from raw material solution to finished powder.

    Centrifugal Spray Dryer

    Centrifugal spray is a kind of spray drying method after the liquid is atomized by a high-speed centrifugal atomizer.

    Pressure Spray Dryer

    Pressure spray is a spray drying method in which liquid is atomized through a spray gun by a high-pressure pump.

    Closed Loop Spray Dryer

    A closed loop spray dryer is a spray drying method that uses inert gas (usually nitrogen) as a circulating medium.

    Spray Dryers Comparison

    When comparing spray dryers, some of the factors that should be considered include: material characteristics, capacity, energy efficiency and cost.

    • The power consumption of the centrifugal spray dryer is between pressure and closed loop spray dryers. It is suitable for high-viscosity or liquid with solids, the output can be adjusted within +25% of the designed capacity without affecting product viscosity. It occupies a smaller area, has a larger capacity, and is more convenient to maintain. Its disadvantages are high manufacturing costs, thicker droplets, and larger nozzles, so the diameter of the spray dryer tower is correspondingly much larger than that of the other two spray dryers.
    • The power consumption of the pressure spray dryer is the lowest (about 4-10kw/h). It is suitable for the feed liquid of general viscosity. The disadvantage is that it must have a high-pressure pump, the nozzle is small and easy to clog, and the production adjustment range is narrow. In addition, the pressure spray dryer is much higher, so the construction cost will be higher.
    • The power consumption of the airflow spray dryer, is the largest, and about 0.4-0.8 kg of compressed air is needed for each kg of feed liquid. However, its structure is simple and easy to manufacture, and it is suitable for any viscosity or slightly solid feed liquid.

    The Parts of Spray Dryers

    For different materials or requirements, the spray drying machine systems we design are also different, but these following 5 main basic units are indispensable.

    Spray Dryer Main Units
    1. Feeding system - Depending on the form of the atomizer used and the nature of the material, the feeding method is also different. Commonly used feeding pumps include screw pumps, metering pumps, and diaphragm pumps.
    2. Heating system - The most important factor in the selection of the heating system is the characteristics of the liquid material. The heating equipment mainly has two types: direct heat supply and indirect heat exchange.
    3. Atomization system - The atomization system is the core of the entire spray drying system. There are three common types: Centrifugal type - the centrifugal force generated by the high-speed rotation of the machine is the main atomization power; Pressure type - the high pressure generated by the feeding pump is the main atomization power; Air flow type - the kinetic energy generated by the airflow is the main atomization power.
    4. Drying system - The type of the dryer depends to some extent on the atomizer. It is also a major part of the spray drying design.
    5. Gas-solid separation system - After the droplets are dried to remove most of the water, they form powder particles, some of which are separated from the gas at the bottom of the drying tower and discharged, and the other part enters the gas-solid separation system with the tail gas and needs to be further separated. There are mainly two types of gas-solid separation: dry separation and wet separation.

    Atomizer Selection Criteria

    Atomizers are used to break down liquids into small droplets or mist. When selecting an atomizer, there are several criteria to consider.

    Spray Dryer Applications

    Spray Drying in Food Industry
    Spray Drying in Food Industry

    Spray drying is a widely used process in the food industry to produce powders from liquids, including dairy product powder (such as milk and whey), coffee and tea extracts, fruit and vegetable powders, vitamins, starches, carbohydrates, flavors and seasonings.

    Spray Drying In Pharmaceutical Industry
    Spray Drying in Pharmaceutical Industry

    Spray drying is particularly useful in the pharmaceutical industry as it enables the production of consistent powders with controlled particle size and morphology. These powders are ideal for the formulation of inhalation products, oral solid dosage forms, and topical formulations.

    Spray Drying In Ceramic Industry
