Spray cooling and spray congealing convert suitable molten waxes, vegetable fats and hydrogenated vegetable fats into solid powders, beads or granules through controlled atomization and cooling. These technologies support industrial applications requiring improved handling, dosing, blending and particle-size control. Successful processing depends on melting behaviour, viscosity, solidification characteristics, cooling conditions and powder recovery. At Delta Formulations, safety is a core value, and relevant material hazards are reviewed before processing. We respect customer confidentiality and request only the information necessary for initial safety and feasibility assessment. Pilot trials help evaluate particle characteristics, processing challenges and the potential for commercial-scale wax and fat powder manufacturing.
Industrial waxes, vegetable fats and hydrogenated vegetable fats are commonly supplied as blocks, flakes, slabs or bulk solid materials. However, many industrial, food, cosmetic and specialty formulation applications require these materials in powder or granular form for improved dosing, blending, handling and downstream processing.
Spray cooling, also known as spray congealing, is a particle-engineering technology that converts suitable molten materials into solid particles through controlled cooling.
During processing, the wax or fat is melted, transferred to an atomization system and converted into droplets. These droplets are cooled and solidified to form powders, beads or granules. The resulting particle characteristics depend on material properties and operating conditions.
Several categories of materials can be considered for feasibility evaluation:
Each material requires individual evaluation because melting temperature, viscosity, crystallization behaviour and thermal stability influence processing feasibility.
Melting temperature and viscosity: The material must remain sufficiently fluid for pumping and atomization while avoiding unnecessary thermal exposure.
Atomization and particle size: Nozzle configuration, melt viscosity, feed rate and atomization conditions influence droplet formation and the final particle-size distribution.
Cooling and solidification: Appropriate cooling conditions are necessary to solidify droplets before collection and minimize sticking, agglomeration and wall deposition.
Powder recovery and stability: Collection efficiency, equipment hold-up, crystallization behaviour and storage temperature can influence powder recovery and final product quality.
Particle-size requirements should be specified using D50, D90 or sieve specifications. Extremely fine powders may require additional micronization technologies.
Wax and fat powders are used in coatings, printing inks, plastics, adhesives, food ingredients, cosmetics and specialty formulations. Depending on the material, they may support lubrication, surface modification, structuring, controlled dosing or improved handling.
Commercial feasibility depends on achieving the required particle-size distribution, powder recovery, flowability and processing consistency. Pilot trials help evaluate these parameters before progressing toward larger production volumes.
At Delta Formulations, safety is one of our core values. We request relevant toxicity, hazard and handling information to protect our operators and everyone involved in processing.
We respect customer confidentiality and do not require unnecessary proprietary component ratios or detailed formulation information for an initial feasibility assessment. Any additional information essential for safe processing can be reviewed through appropriate confidential arrangements.
