As the name implies, a pecan sheller is an apparatus designed to crack open the pecan shell while protecting the nut from damage. There are various types of pecan shellers, each with distinct features.
Manual pecan sheller
For numerous generations, manual pecan shellers have been ubiquitous throughout the southern USA. Therefore, they are inexpensive, uncomplicated shellers without electrical features. Usually, wood or metal makes up the manual shellers. The main components are the shell-cracking mechanism and the hand lever. The user inserts the pecan into the sheller after cranking the lever, and the sheller manually cracks the pecan's shell. Manual pecan shellers depend on the user's physical effort to crack the pecans, thus controlling the force and handling with ease.
Electric pecan sheller
An electric pecan sheller offers a faster and more efficient alternative to manual effort, making it appropriate for handling large quantities of pecans. Typically made of durable metal components, electric pecan shellers are powered by electricity and have motor-driven mechanisms to crack the shells. Electric pecan shellers are easy to operate; users insert the pecans, and the electric sheller cracks the shells automatically. The working principle relies on rotating blades or hoppers to crack pecans.
Stranded pecan sheller
This kind of sheller has been the most prevalent in pecan shelling plants. Its design is based on the strand, which is analogous to a strand of wire, contacting the pecan to perform the deliverable task, thereby eliminating the necessity of wide openings. An additional benefit is that it results in an increased throughput and recovery, decreasing the number of pecans left in the shells and lowering the number of shell pieces in the output, which is called the product left behind.
The functionality of pecan shellers depends on various specifications. When buying, it is essential to check the specifications to ensure they meet the requirements.
Applicable Kernel Size
Pecan shelling machines are designed to accommodate specific kernel sizes. Select a sheller that is compatible with the size of pecan nuts. Using the machine on nuts that are too small or large can lead to inefficient shelling and excessive damage to the kernels.
Shelling Efficiency
Consider the shelling efficiency of the pecan shelling machine, which is usually expressed as the percentage of shelled nuts to the total nuts input. Choose a machine that offers high shelling efficiency to minimize the time and labor required for shelling.
Suction-based Cleaning Systems
Some pecan shellers are equipped with suction-based cleaning systems, which use powerful vacuums to remove shells and debris from the output stream. This innovative cleaning method minimizes cross-contamination and ensures that only clean, shelled nuts are collected. Consider shellers with suction-based cleaning systems for efficient cleaning and improved product quality.
Adjustable Shelling Plates
Pecan shelling machines utilize adjustable shelling plates for customization. The shelling plates can be reconfigured to adapt to various pecan sizes and achieve desired shelling ratios. This enables precise control over the shelling process, reducing the risk of damage to the nuts and ensuring optimal shelling results.
Capacity
The capacity of a pecan sheller refers to the amount of pecans it can process per hour. Choose a capacity that aligns with the expected volume of pecans to be shelled to meet production demands effectively.
Power Requirements
Consider the power requirements of the pecan sheller. This includes the voltage and wattage needed to operate the machine. Ensure the power supply can support the consumption during operation.
In order to keep the pecan shellers in good conditions, it is necessary to follow the maintenance tips aptly.
Regular Inspection
Conduct routine inspections to the pecan sheller. Take time to check for signs of wear, damage, and loose or malfunctioning parts. Repair or replace any parts that show issues to ensure the machine functions well over the years.
Lubrication
Pay attention to critical components and moving parts of the shelling machine. For example, lubricant can be grease or oil. Lubrication can reduce friction, extend the lifespan of the pecan sheller, and enhance operational efficiency.
Deep Cleaning
Clean up debris and pecan residue after use. Besides, users can perform a thorough cleaning of the entire sheller on a regular basis. Avoid the build-up of shell fragments and dust to reduce the risk of contamination and ensure product quality.
High-volume pecan processing plants
Large-scale pecan processing plants that handle huge quantities of pecans each day are among the core application areas for industrial pecan shellers. These plants frequently require high-capacity shellers in order to efficiently shell hundreds of kilograms or even tons of pecans every day. Because of their ability to process large volumes and their durability in demanding situations, industrial pecan shellers are a popular choice for large-scale processing facilities.
Commercial tartrate recovery operations
Commercial tart pecan recovery enterprises that aim to extract as many edible pecan pieces as possible from shelled pecans are another significant application area for industrial pecan shellers. These operations frequently employ industrial pecan shellers equipped with sophisticated separation and classification systems to effectively separate shelled pecans from fractured pecans. This aids in maximizing pecan recovery rates, minimizing waste, and boosting yield efficiency, all of which are crucial concerns for commercial tart pecan recovery operations.
Food processing companies
Food processing firms that utilize pecans as raw materials to manufacture various food products are another application area for industrial pecan shellers. These products may include snacks that are pecan-based, granola bars, and baked goods, among others. Industrial pecan shellers assist food processing companies swiftly and effectively shelling pecans, providing raw materials for subsequent processing and production.
Export packing facilities
Export packing facilities that prepare shelled pecans for overseas markets are also an application area for industrial pecan shellers. These facilities need to comply with strict export standards and shell pecans ready for packing and export. Industrial pecan shellers assist these facilities in meeting export specifications, facilitating overseas trade.
Agricultural cooperatives
Agricultural cooperatives that are in charge of processing farmer-produced pecans and marketing them are also an application area for industrial pecan shellers. These cooperatives require to shell a variety of pecan products for sale to supermarkets or other end users. Agricultural cooperatives can process pecans produced by farmers thanks to industrial pecan shellers and sell them on the open market, thus helping farmers get a higher income.
Research and educational institutions
Research and educational institutions that conduct research or teach related to pecan processing are also an application area for industrial pecan shellers. These institutions may use industrial pecan shellers for experiment design, technical research, or educational demonstrations. Industrial pecan shellers provide a hands-on teaching and research tool for these institutions, helping to advance technical progress and knowledge popularization in the field of pecan processing.
When ordering industrial pecan shellers, ensure they have important features like good capacity, efficiency, and stability. The ability to process large quantities of nuts is essential for meeting demand. Therefore, check the capacity and adjustability of the shellers before placing the order.
Select pecan shellers with high separation efficiency to minimize losses. Look for models that can separate out the broken shells and empty nuts quickly and accurately. The more efficiently the sheller separates the nuts from the shells, the less time workers will have to spend on manual separation later, thus boosting productivity.
Furthermore, choose pecan shellers built to last and withstand regular use in commercial settings. They should have durable components, such as quality blades and screens, that won't wear out easily. Also, the shellers should be user-friendly, with simple controls and clear instructions so staff can learn to operate them with minimal training.
It is good to select shellers with various settings to accommodate different nut sizes and shell thicknesses. Adjustable feeding speeds, blade positions, and screening methods allow the equipment to process pecans at distinct growth stages efficiently.
Finally, consider the maintenance requirements and availability of spare parts. Selecting shellers with low maintenance needs and easy-to-replace parts will help keep the equipment running smoothly over the years. Conducting research into the proven track record of the sheller supplier will also facilitate long-term support and service.
