• What is the primary purpose of a plate heat exchanger in dairy

processing?

• Increase milk fat content
• Sterilize equipment
• Reduce milk viscosity
• Rapidly heat and cool milk

Rationale: Plate heat exchangers allow fast temperature changes essential

for pasteurization and product safety.

• Which component is responsible for creating vacuum in a milking

system? 1 / 3

• Pulsator
• Milk pump
• Vacuum pump
• Compressor

Rationale: The vacuum pump generates the vacuum needed to extract milk

from the udder.

3. The typical vacuum level in a dairy milking system is:

• 15–20 kPa
• 40–50 kPa
• 70–80 kPa
• 5–10 kPa

Rationale: Standard milking systems operate around 40–50 kPa to ensure

gentle, effective milking.

• What is the common material for dairy pipelines due to hygiene

requirements?

• Aluminum
• Copper
• Stainless steel
• Brass

Rationale: Stainless steel resists corrosion and is easily sanitized.

• What does CIP stand for in dairy equipment cleaning? 2 / 3

• Clean in Panel
• Clean in Place
• Chemical Internal Purge
• Cold Internal Processing

Rationale: CIP allows cleaning without dismantling equipment.

• Which chemical is commonly used in dairy alkaline cleaning cycles?
• Nitric acid
• Sodium hydroxide
• Hydrochloric acid
• Peroxide

Rationale: Sodium hydroxide removes proteins and organic deposits.

• Which sensor ensures correct temperature during pasteurization?
• Flow sensor
• Temperature probe
• Pressure gauge
• Conductivity sensor

Rationale: Temperature probes measure critical pasteurization

temperatures.

8. A faulty pulsator in a milking machine mainly affects:

• Milk taste
• Milking rhythm
• Cleaning cycle
