Question

Match List I with List II 

 Choose the correct answer from the options given below: 
 

• A. A - I, B - III, C - IV, D - II
• B. A - III, B - I, C - II, D - IV
• C. A - III, B - I, C - IV, D - II
• D. A - I, B - III, C - II, D - IV

Hint:

To remember the size reduction laws:
- Kick's Law \(\rightarrow\) Energy is proportional to the ratio of sizes (Size reduction).
- Rittinger's Law \(\rightarrow\) Energy is proportional to the new surface area created.
- Bond's Law \(\rightarrow\) Energy is proportional to the square root of the product size.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Agricultural process engineering utilizes several physical laws and thermal processes to preserve, sort, and process biological materials.
These include phase-change drying, mass-transfer laws, density-based sorting, and energy laws of comminution.

Step 2: Detailed Explanation:
Let us match each item in List I with its corresponding principle or process in List II:
- A. Freeze dryer: Freeze drying (lyophilization) is a low-temperature dehydration process.
It involves freezing the product and then reducing the surrounding pressure to allow the frozen water in the material to transition directly from the solid phase to the gas phase. This phase change is known as Sublimation (III).
- B. Specific gravity separator: This equipment is used to separate seeds or grains of the same size but with different weights.
It utilizes a deck that moves with fluidizing air blowing through it, causing the material to separate based on differences in its Density (I).
- C. Fick's law: This law describes the physical process of mass transfer.
It states that the flux of a diffusing substance is directly proportional to the concentration gradient. This is the fundamental law governing molecular Diffusion (IV).
- D. Kick's law: This is one of the classical theories used to calculate the energy required for comminution.
It states that the energy needed to crush a given quantity of material is constant for a constant ratio of Size reduction (II).
The correct matching sequence is: A-III, B-I, C-IV, D-II.

Step 3: Final Answer:
The correct option is (C).
