Improved spray drying, powder quality and cleaning hygiene with Click&Dry spray dry nozzle

Click & Dry spray nozzle. Unique Features Seal Face Protection-SkirtThe increased production of Milk Powder for Infant Formula is placing ever increasing demand on powder quality and the need for higher levels of cleaning efficiency and hygiene in plants. The spray dry nozzle used, plays a critical role in achieving these gains.

To achieve gains in this process, the Spray Dry nozzles offered by Spray Nozzle Engineering, provide improved performance whilst being easy to clean.

CLICK&DRYTM Nozzles have made cleaning and hygiene easier.

The CLICK&DRYTM Spray Dry Nozzle system is designed with improved cleaning and maintenance in mind.

With its Smooth Cap Chamber Technology, all CLICK&DRYTM Spray Dry Nozzle Caps do not use O-Ring sealing grooves that can harbour contaminants.

Hygiene is improved with a totally smooth and easy to clean cap chamber design. Engineers at Spray Nozzle Engineering have perfected CLICK&DRYTM spray dry series to address all areas of performance including easier cleaning, productivity, powder quality, faster change-outs, reduced nozzle build up, reduced scorched particles along with long-term cost savings. Spray Nozzle Engineering are so confident with the longevity of CLICK&DRYTM products, that when operated within the terms of supply, they are the first in the world to offer a replacement guarantee on key components.

Entry level performance gains:

  • Longer Run Times
  • Reduced Scorched Particles
  • Reduced Build Up Bearding
  • Wider Spray Angles Possible

Bete spray drying nozzles

Spray drying is used by many industries to quickly and inexpensively transform food products, chemicals, and other products into dried powders. Powder is preferable because it has drastically reduced weight and increased storage life.

Spray drying can be accomplished across a range of powder production rates, from a few pounds per hour to over 100 tons per hour.

The basic process is to first concentrate the feed stock in a liquid form, atomise it at high pressure to create small droplets consisting of liquid and particles, then allow a hot gas to evaporate the liquid away leaving only the dry particulate.

The sprayed media feed stock can be a solution, slurry, paste, gel, suspension or a melt, as long as it has a solid component and a liquid component to carry the solids through the piping and then evaporate in the drying chamber. Any liquid that can be pumped can be spray dried, including feed stocks that are abrasive, corrosive, flammable, explosive, or toxic. Since the uses vary so much, a wide array of atomisers must be considered.

The function of a spray nozzle in a spray dry system is to control the feed stock flow rate and uniformly distribute atomised droplets/particles into the heated drying chamber.

Spray dry nozzles typically operate at higher pressures or utilise air-atomising techniques to produce droplets in the 30 – 120 micron range. This maximises the surface area to volume of the particles, allowing them to dry much quicker than other drying methods. In many dryers, evaporation is 95% complete within seconds.

BETE produces a variety of hydraulic and air-atomising nozzle types, features, and materials to fit your spray drying applications requirements.

Consistent performance and quality allow for the production of high quality products through constant particles sizes with even moisture content.

High strength, wear resistant, and high temperature material options allow for long service life and safe operation within the high pressure, high temperature, and abrasive applications found in the spray drying industry.

  • XAER Nozzles

    Design features of the XAER air atomising, pneumatic, pressure fed, external mix, round spray nozzle:
    • External mix: allows spraying of viscous materials
    • Able to spray high viscosity (100+ cP) fluids which require a round spray pattern
    • Liquid flow rate is controlled only by the liquid pressure. Liquid flow rate is not dependent on the air pressure making the nozzle performance easier to control.

    Design Features:

    • Patented locking mechanism for quick and easy change-out and maintenance
  • Dip-Pro Check Valves for Spray Drying

    Reducing scorched particle contamination and post shut drip

    The Drip-Pro is the Spray Nozzle Engineering check valve for the Click&Dry series, also known as non-return valve and reflux valve, this valve works automatically without external control or intervention. The check valve allows fluid (liquid or gas) to flow in only one direction; it will crack (open) at a minimum pressure preventing inconsistent start up flow, and reseal (close) upon shut down to further prevent undesirable drips leading to scorched particles and product contamination.
