Question

Identify the equipment in the image: 

• A. Homogeniser
• B. Clarifier
• C. Batch pasteurizer
• D. HTST pasteurizer

Hint:

Look for the key feature: a stack of conical discs inside a spinning bowl. This is the hallmark of a centrifugal separator, used for clarification and cream separation in the dairy industry.

Answer 1

The Correct Option is B

Step 1: Analyze the equipment's visual characteristics.The image depicts a centrifugal separator, recognizable by its large bowl containing a stack of conical discs. This design utilizes high-speed rotation to separate substances based on density.
Step 2: Connect the design to its function and the provided options.This equipment employs centrifugal force to separate liquid components. In the dairy sector, it serves two primary functions: separating cream (fat) from skim milk and eliminating solid impurities (sediment, somatic cells) from raw milk.

Homogeniser: A homogenizer uses high pressure to force milk through small openings, breaking down fat globules. Its appearance differs significantly from the image.
Clarifier: A clarifier, a type of centrifugal separator, is specifically designed for removing solid particles from liquids. The depicted equipment is a typical milk clarifier, also capable of cream separation, making this the correct identification.
Pasteurizers (Batch or HTST): Pasteurizers, either batch or HTST (High-Temperature Short-Time), utilize heat exchangers (large vats or plate systems) to heat milk for pathogen elimination. They lack the centrifugal bowl design shown.\end{itemize}The equipment is a centrifugal separator functioning as a clarifier. Therefore, "Clarifier" is the most accurate description from the given options.
