Food Grade Stainless Steel Industrial Spray Drying Machine For Milk Powder Egg White Coffee Tea Powder Production

This food grade stainless steel spray dryer machine brings centrifugal spray drying technology to dairy, egg and instant beverage processors who must combine gentle drying with strict hygiene. Milk, egg white liquid, animal blood meal slurry, coffee extract and tea extract are atomized into fine droplets and dried in parallel hot air flow within seconds, which preserves natural color, aroma and nutritional value far better than prolonged heat exposure. The chamber is built from food grade stainless steel with smooth surfaces and continuous powder discharge, so cleaning between product runs is fast and contamination risk stays low.

• Sanitary food grade construction: SUS304 food grade stainless steel chamber, smooth welded surfaces and easy access make wash down cleaning straightforward.
• Gentle seconds long drying: 95%-98% of water evaporates instantly, keeping milk proteins, egg albumen and beverage aromas intact.
• Excellent powder solubility: final powder shows good uniformity, flow ability and solubility, giving instant products fast reconstitution.
• Low temperature protection: the extremely short drying time suits heat sensitive food components such as proteins, enzymes and volatile flavors.
• Hygienic powder collection: cyclone separator and bag filter recover powder continuously inside a closed flow path, meeting food safety expectations.
• Flexible food grade output: particle size, looseness and moisture are adjustable, from fine milk powder to coarser instant beverage granules.

Air is first filtered and heated, then enters the air distributor at the top of the drying tower, where it spirals evenly down into the drying chamber. The liquid feed is pumped to a high-speed centrifugal atomizer mounted at the top of the tower and is atomized into extremely fine droplets, which come into contact with the hot air in a parallel flow. Water on the surface of the droplets evaporates almost instantly, so the material is dried into a finished powder in only a few seconds. The finished product is discharged continuously from the bottom of the drying tower and collected through a cyclone separator and a bag filter, while the exhaust gas is vented by an induced draft fan. Because the whole drying step is so short, the machine is especially suitable for heat sensitive materials.

This machine is widely applied in the food industry for milk powder, egg white powder, animal blood meal and soluble protein, and in the beverage and plant processing sector for instant coffee, instant tea, seasonings, meat extracts, soybean products and hydrolysates. It is a reliable choice for dairies, egg processing plants and instant food factories that need consistent powder quality, high solubility and easy sanitation between batches of different products.
