Question
Which one is a common equipment used for size reduction of food grains ?
The correct answer is
Hammer mill
Food Grain Size Reduction Equipment
Size reduction of food grains involves breaking down larger particles into smaller ones. This is often necessary for improving texture, digestibility, or preparing grains for further processing like baking or brewing.
Evaluating Equipment for Size Reduction
- Centrifuge: This equipment separates components based on density using centrifugal force. It is not used for grinding or reducing the size of food grains.
- Filter press: Used for separating solids from liquids or gases. Its function is filtration, not size reduction of grains.
- Hammer mill: This mill uses rotating hammers to strike and shatter grain particles. It is a very common and effective machine for the size reduction (grinding) of various food grains, turning them into flour or meal.
- Plate heat exchanger: This device is designed for efficient heat transfer between fluids. It is unrelated to size reduction processes.
Correct Equipment Identification
The Hammer mill is specifically designed for the mechanical breakdown and size reduction of materials like food grains through impact.
