For the production of Shortening, Margarine and Table Spread, different raw materials (different oils and water) are taken in different quantities as per a pre-defined recipe, to which emulsifiers, anti- oxidants and other ingredients are added manually to make a homogenous emulsion ready to be fed to the processing section. For batching, two tanks mandatory for all products are the Premix tank and the Buffer tank. The premix tank stands on three live load cells while the batching system automatically transfers different oils from different tanks as required by the recipe selected. Buffer tank continuously supplies the blend to the processing section while the next batch is prepared in the Premix Tank. Shortening can be prepared with the help of only the Premix and the Buffer Tank.

However, for the production of Margarine, it is required to add at least two more tanks of smaller capacities namely the Emulsifier Tank and the Water Phase Tank. Both these tanks also stand on live load cells and are integrated into the batching system to optimize production. Furthermore, for the manufacture of products with SMP or Cocoa optionally an additional would be required with a High Shear Blender will be required to blend SMP and form a homogeneous solution before transferring it to the Premix Tank. Though these is the minimum requirement for the production of Margarine, it is sometimes preferred to have a Water Storage Tank with a dedicated hot water circulation system, twin tanks for Emulsifier and Water Phase and a Fat remelter. A sample Flow chart for Batching Systems for Margarine supplied by SIPEPL is as below, however the Batching system is made as per the requirement of the Customer after evaluating the different products he wishes to produce.
