Benefits of BETE Spray Drying Nozzle Technology

A spray drying nozzle is a specialized nozzle designed to break down a liquid into a fine mist, which is then dried by hot air and collected as powder. This process, known as spray drying, has many applications in producing different powders, such as food, pharmaceutical, and industrial powders. Various types of spray drying nozzles are available, each having unique advantages and disadvantages. The most commonly used type is the rotary atomizer, which employs a spinning disk with small perforated holes to atomize the liquid under pressure. The resulting mist is then dried using hot air.


In this article, we will delve into the details of spray drying nozzles and the various types of nozzles available, their applications, and the benefits of using BETE’s spray drying nozzles.

Types of Spray Drying Nozzles


Spray drying nozzles come in different types, each with unique features that make them suitable for specific applications. The most commonly used type of spray drying nozzle is the rotary atomizer. The rotary atomizer employs a spinning disk with small perforated holes to atomize the liquid under pressure. The resulting mist is then dried using hot air. Other types of nozzles include pressure, airless, and ultrasonic nozzles.



Spray drying nozzles are used in several applications, including the food, pharmaceutical, and industrial sectors. For example, spray drying technology is employed in the food industry to create a broad range of food powders, including milk, coffee, and soup powders. These powders are easy to use, have a longer shelf life, and offer convenience to consumers. In the pharmaceutical industry, spray drying produces high-purity powders such as antibiotics, vitamins, and hormones, free from contaminants and suitable for drug formulations. The industrial sector uses spray drying to create uniform powders of pigments, catalysts, and detergents ideal for various applications. It’s important to note that the quality of the powder produced depends heavily on the type of spray drying nozzle used.


Benefits of BETE’s Nozzles


Spray drying nozzles are becoming increasingly popular because they can produce fine, consistent powders with high efficiency. They are especially useful for transforming liquid products into powders, which makes them easier to handle, store, and transport. Spray drying nozzles can be used with various liquids, including solutions, suspensions, emulsions, and slurries. This versatility allows for producing multiple products, such as food powders, pharmaceuticals, and industrial materials. Overall, the benefits of spray drying nozzles make them an essential part of many manufacturing processes. They help to improve productivity and efficiency while maintaining high-quality standards.


BETE offers four different premium quality options of spray drying nozzles. The TD/TDK “Twist & Dry” line maximizes durability and minimizes maintenance. The TDL “Twist & Dry” line was designed for low flow while boasting a compact design. The TD-HT “Twist & Dry” option can be utilized in higher-temperature environments or with high-temperature mediums. A common problem in the dry spray industry is post-nozzle drip, which causes scorched particles that compromise product quality. However, the “Drip-Pro” Check Valve spray drying nozzles were manufactured to prevent nozzle drips – perfect for painting or rust prevention. Each of the four aforementioned product lines can be inspected more thoroughly by reviewing the individual pages for the nozzles.


BETE is a fourth-generation family-owned company founded in Greenfield, MA, in 1950. It has grown to have a prominent international presence in many countries because of innovations that improve sustainable operations in various industries–including Food & Beverage Processing, Chemical Processing, Energy, and Pollution Control.
