Top 10 Questions for Pea Viner Mechanic Interview

1. Describe the key components and functions of a pea viner machine.

• The pea viner machine consists of a hopper at the top of the machine where the raw peas are fed into.
• The rotating cylinder inside the machine is equipped with a series of rasp bars that beat the pea pods, separating the peas from the vines.
• The debris and vines are then discharged through a separate chute, while the peas are collected in a bin or conveyor belt.

2. Explain the principle behind the separation of peas from vines in a pea viner machine.

Mechanical Impact

• The rotating rasp bars strike the pea pods with force, breaking the pods open and releasing the peas.
• The impact also loosens the vines, facilitating their separation from the peas.

Centrifugal Force

• The high rotational speed of the cylinder creates centrifugal force, which helps to eject the debris and vines from the machine.
• The peas, being heavier, remain within the cylinder until they are discharged through the exit chute.

3. How do you adjust the pea viner machine to optimise pea separation efficiency?

• Adjust the speed of the rotating cylinder to control the intensity and frequency of impacts.
• Ensure the spacing between the rasp bars is appropriate for the size and variety of peas being processed.
• Check the alignment of the rasp bars to prevent damage to the peas.

4. Describe the common maintenance tasks required for pea viner machines.

• Regularly inspect and lubricate all moving parts, including the bearings and gears.
• Clean the machine thoroughly after each use to prevent debris buildup.
• Check the rasp bars for wear and replace them if necessary to maintain optimal separation efficiency.

5. How do you troubleshoot a pea viner machine that is not separating peas effectively?

• Check if the cylinder is rotating at the correct speed.
• Inspect the rasp bars for damage or misalignment.
• Ensure that the machine is properly adjusted for the size and variety of peas being processed.

6. Explain how you would determine the capacity of a pea viner machine.

• The capacity of a pea viner machine is typically measured in pounds or tons of peas processed per hour.
• Factors that affect the capacity include the size and condition of the machine, the variety of peas being processed, and the desired separation efficiency.

7. How do you ensure the safety of operators when working with a pea viner machine?

• Provide proper training to operators on the safe operation and maintenance of the machine.
• Install safety guards around all moving parts to prevent injury.
• Instruct operators to wear appropriate protective gear, such as gloves and earplugs.

8. Describe the different types of pea viners and their respective advantages and disadvantages.

• Cylinder pea viners: Efficient and suitable for large-scale operations, but can cause more damage to peas than other types.
• Flail pea viners: More gentle on peas, but may have lower separation efficiency than cylinder viners.
• Podding pea viners: Designed to remove both the peas and the skins, producing a cleaner product.

9. How do you maintain the quality of peas during the vining process?

• Minimise the impact force on the peas by adjusting the speed and spacing of the rasp bars.
• Keep the machine clean to prevent contamination.
• Handle the peas gently during loading and unloading to avoid bruising.

10. What are the key factors to consider when choosing a pea viner machine for a specific application?

• The capacity required to meet the production needs.
• The type of peas being processed (size, variety, condition).
• The desired separation efficiency and pea quality.

Pea Viner Mechanics play a crucial role in ensuring the efficient operation of pea viners, specialized machines used to harvest peas. They are responsible for maintaining, repairing, and troubleshooting these machines to maximize productivity and minimize downtime.

1. Maintenance and Inspection

Pea Viner Mechanics conduct regular maintenance checks to ensure that all components are in good working order. They inspect belts, chains, bearings, and other critical parts for signs of wear or damage, and perform necessary adjustments or replacements.

2. Repairs and Overhauls

When pea viners experience mechanical issues, Pea Viner Mechanics diagnose and repair the problems promptly. They use specialized tools and techniques to address a wide range of issues, from minor repairs to major overhauls.

3. Troubleshooting and Diagnostics

Pea Viner Mechanics are skilled in troubleshooting and identifying the root cause of mechanical problems. They analyze machine behavior, conduct tests, and use their knowledge of pea viner operations to resolve issues and restore functionality.

4. Preventive Maintenance

To prevent costly breakdowns and extend the lifespan of pea viners, Pea Viner Mechanics implement preventive maintenance programs. They perform scheduled inspections, lubrication, and other preventive measures to ensure optimal performance and reliability.
