Lactoferrin Powder Manufacturing Process
Spray Drying Process
Lactoferrin is pasteurized at 63°C for 30 minutes and passed on to the drying chamber through a centrifugal pump. The atomizer at the top of the drying chamber, converts the Lactoferrin liquid into small droplets and sprays at a high speed inside the chamber which contains hot air. As the droplets dry midway, the Lactoferrin powder falls at the bottom of the chamber where it is directly packed aseptically under controlled conditions.
lyophilized Process
As the name suggests, this process involves freezing the product and evaporating the moisture out of the product to get the final powder. This is the best process to dry products which are heat labile in nature so as to preserve the nutritional value. Very few industry players prefer this process due to severe limitations in production capacity and tremendous operating cost which increases the price of the finished product. However, there is no doubt that this is the best process to manufacture premium quality Lactoferrin powder.
