Devyani International Technician Interview Questions and Answers

The refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature area and releases it in a high-temperature area.

• The refrigeration cycle starts with the refrigerant entering the compressor as a low-pressure gas.

• The compressor then compresses the refrigerant, raising its temperature and pressure.

• The high-pressure, high-temperature refrigerant gas then flows into the condenser where it rele...read more

A chiller plant typically goes through multiple cycles to cool a building or facility.

• A chiller plant usually has multiple cycles throughout the day to maintain the desired temperature in a building.

• The number of cycles can vary depending on factors such as the size of the building, weather conditions, and cooling load.

• For example, a chiller plant in a large office building may go through several cycles during peak hou...read more

HT line refers to high tension line used for transmitting electricity over long distances.

• HT line is used for transmitting electricity at high voltages to reduce energy losses during transmission.

• These lines are typically supported by tall towers to keep them at a safe distance from the ground.

• Examples of HT lines include overhead power lines used by electric utilities to distribute electricity.

• HT lines are crucial for...read more

LT line refers to Low Tension line, which is a distribution line carrying electricity at a lower voltage.

• LT line carries electricity at a voltage lower than 1000 volts.

• It is used for distributing electricity to residential and small commercial buildings.

• LT lines are typically overhead lines supported by poles or underground cables.

• Examples of LT lines include power lines in residential neighborhoods and small businesse

• The maximum temperature can range from around 200 degrees Celsius to 300 degrees Celsius.

• The specific temperature range will be mentioned in the oven's user manual or specifications.

• For example, the Domino XYZ model has a minimum te...read more

The oven conveyor running speed at Domino's varies depending on the specific oven model and the type of pizza being cooked.

• The oven conveyor speed is typically set to ensure that pizzas are cooked evenly and efficiently.

• Different types of pizzas may require different conveyor speeds to achieve the desired level of doneness.

• The conveyor speed can be adjusted manually or automatically based on the oven's programming.

• Domi...read more

The conveyor running speed is an important parameter that determines the efficiency and productivity of the system.

• The running speed of the conveyor should be optimized to ensure smooth and efficient material handling.

• Higher running speeds can increase throughput but may require additional safety measures.

• Lower running speeds can reduce the risk of accidents but may decrease productivity.

• The conveyor running speed can ...read more

Mecline is kept at a temperature of 25 degrees Celsius in Domino.

• Mecline is stored at a specific temperature in Domino.

• The temperature at which Mecline is kept is 25 degrees Celsius.

• Maintaining the correct temperature is important for the stability and effectiveness of Mecline.

• Temperature control ensures the quality and integrity of Mecline.

• Incorrect storage temperature can affect the potency and shelf life of Mecline.
