Nut Conveying with Bucket Elevators: Gentle Handling of Peanuts, Almonds and Cashews
Gentle conveying solutions for peanuts, almonds and cashews. Learn how pendulum (Z-type) bucket elevators help minimize product breakage.
Why Is Gentle Conveying Important in Nut Processing?
Maintaining product quality is an important part of nut processing and packaging operations. Products such as peanuts, almonds and cashews can be sensitive to mechanical impact, which may cause cracking, breakage or product damage during conveying.
Nuts often need to be transferred between cleaning, roasting, cooling, sorting and packaging processes. The design of conveyors and bucket elevators can directly influence product integrity throughout these operations.
For this reason, selecting a conveying system for nuts and snack foods is not only about capacity. How the product is transported and discharged is equally important.
Challenges in Conveying Peanuts, Almonds and Cashews
Different types of nuts have different shapes, sizes and mechanical characteristics.
- Peanuts: Shelled peanuts, particularly kernels without shells, may be susceptible to splitting and breakage.
- Almonds: Mechanical impacts can increase the proportion of cracked or broken kernels.
- Cashews: Their curved shape and physical characteristics make careful handling particularly important.
High conveying speeds, uncontrolled discharge, impacts against hard surfaces and excessive free-fall heights can contribute to product damage.
Therefore, conveying systems that provide a controlled product flow may be preferable for fragile products.
Gentle Handling with Z-Type Bucket Elevators
Pendulum bucket elevators, also known as Z-type bucket elevators, are among the solutions used for gentle horizontal and vertical conveying of sensitive products.
Unlike conventional centrifugal discharge elevators, pendulum bucket elevators use freely suspended buckets.
Instead of throwing the product out at high speed, the buckets are tilted at designated discharge points, allowing controlled product discharge.
This operating principle can provide several advantages:
- Low conveying speeds
- Controlled product discharge
- Reduced risk of product breakage and damage
- Horizontal and vertical conveying within one system
- Multiple discharge points when required
However, actual breakage rates depend on product characteristics, capacity and system design. Product testing is therefore an important part of equipment selection.

Simatek pendulum bucket elevators can be used to handle different types of nuts with varying shapes and sizes.
The following video demonstrates the conveying of peanuts, almonds and cashews.
The video illustrates how different products move through the bucket conveying system and helps demonstrate its operating principle.
Selecting the Right Bucket Elevator for Nut Processing
When designing a nut conveying system, several factors should be considered together, including product type, fragility, required capacity, conveying height and discharge locations.
Cleaning requirements and product changeovers should also be evaluated, particularly in facilities processing different types of nuts on the same production line.
Simatek SBS PenduLift pendulum bucket elevators are among the solutions that can be considered for applications requiring gentle handling and controlled discharge.
Conclusion
When conveying peanuts, almonds and cashews, the objective is to transport the product while preserving its physical integrity as much as possible.
With low conveying speeds and controlled discharge, Z-type bucket elevators can be a suitable solution for nut processing and packaging plants where minimizing product breakage is important.
The appropriate conveying system should always be selected according to product characteristics and process requirements.
