Liquid Milk Processing Plant

Raw/Chilled milk from chilling center is received in a dump tank. It is then chilled in a PHE type chiller upto 4 deg C. The chilled milk is then stored to chilled milk storage tank, from where it is pumped to pasteurizer and through pasteurizer it goes to cream separator. Cream is separated through milk and skim milk is obtained. Milk/ skim milk is standardized with cream, butter oil, SMP to make Full cream milk, standardized milk, toned milk, double toned milk and skim milk. The milk is packed in ½ kg and 1 kg plastic pouches.

The separated cream is processed to manufacture butter, butter oil and ghee. Cream from cream storage tank goes to butter churn, then ghee boiler, ghee settling tank, ghee prestratification tank, ghee clarifier to manufacture ghee. Ghee is packed either in tin or poly pouches.

Dried milk powder is the product obtained by the removal of water from milk by heat or other suitable means, to produce a solid containing 3.5 % or less moisture. Whole milk, skim milk may be used for drying. The dried product obtained from whole milk is called whole milk powder; from skim milk is known skim milk powder.

Salient features of FBE Make Evaporators

• Adjustable and controllable direct contact heat treatment units.
• Shortest possible residence time.
• Special design to prevent bacteriological growth including thermophiles.
• Special design of liquid distribution systems to ensure correct tube coverage.
• Extended tube length.
• Efficient design of separators.
• Low energy consumption (Steam, Power, cooling water).
• Easy operation.
• No scale formation in tubes.

Salient features of FBE Make Dryers

• Good plant performance due to the absence of any air flow obstruction inside the chamber
• Good agglomeration potential.
• Instant quality of powder is formed.
• Higher plant capacity for a given size.
• Low energy consumption.
• Alternate arrangements of Rotary atomization or nozzles in the same dryer
• Used for the whole range of dairy products as the SMP, WMP, DW etc.
• Single stage spray dryer and Spray dryer with IBD and VFD shall be used alternately in the same plant
• Fines-return to atomization device or VF
• Pneumatic cooling and conveying system in stead of VF
• Pneumatic cooling and conveying system in stead of VF
• Air exhaust through centre duct in the chamber.

Advantage of Lecithinization system

• Lecithinization system is integrated with Spray dryer to manufacture Whole milk powder.
• The lecithinization refers to the coating of powder by a wetting agent consist of lecithin dissolved in butter oil. The wetting agent is sprayed to powder under fluidization in VFD, so that good quality of WMP s produced with it.

Condensed milk is the product obtained by evaporating part of the water of whole milk, or fully or partly skimmed milk, with or without addition of sugar.
