Kernel and shell separators are used to separate the good product from the discarded shells after processing certain fruits like walnuts, hazelnuts, etc. Depending on the type of fruit and the processing methods, different kinds of kernel and shell separators are available.
Kinfe separator
A typical separator consists of a moving and a fixed blade. The moving blade moves up and down and creates an opening between the two blades where the kernel goes through while the shell is left behind. This simple separator can be used in manual or electric form, and although it works on the principle of cutting, it is less harmful to the product.
Disc separators
Disc separators usually work on the principles of centrifugation. Discs are stacked on a central spindle, and the mixture is fed from the top. The mixture moves outward within the discs under the influence of centrifugal force. Kernel and shells separate based on size and density when they reach the edge of the disc and fall in different directions. The exact configuration of the discs and their distance apart varies based on what material is being separated.
Suction separators
This type of separator works on the principle of using air to separate the kernel from the shell. It usually consists of a fan and a sieve. The fan blows air on the mixed material, and light particles like the shell are blown away while the heavier ones settle down. Fine-tuning the speed of the fan allows operators to control the separation process. The advantage of this kind of separation is that no mechanical force is used, and the product is preserved.
Electronic separator
Modern-day kernel and shell separators use electronics to improve separation accuracy. These separators have sensors to detect kernels and shells based on size, shape, and other parameters. A programmable logic controller or PLC is used to separate the two based on the different identities created by the sensors. This kind of separator offers high precision and can separate materials that other kinds of separators cannot. The main disadvantage is that these kinds of mechanical separators can be costly to maintain and operate.
Kernel and shell separators have various specifications depending on the design and the intended use. This includes capacity, power consumption, and efficiency.
Some kernel and shell separators work automatically by feeding in nuts and taking out separate nuts and shells. Others may be partly or totally manual. Partly manual models have a conveyor that will require the nut to be put on it, while fully manual models will require the nuts to be manually fed into them. Fully automated ones are more expensive, and partly automated or entirely manual will be more affordable but require more labor to run.
The maintenance of the kernel and shell separator is important, so it separates kernel and shell pieces smoothly and efficiently. The main types of separators are centrifuge separators, sieve separators, along with air blast separators, which basically all require the same type of maintenance.
Before beginning maintenance, it is always important to consult the manuals of the specific models that are being maintained. Use the procedures and guidelines mentioned.
Some general maintenance procedures that are common to all types are listed below.
Efficient separation depends on the accurate alignment of separator core components. Alignment should be checked regularly, and adjustments should be made whenever necessary.
Operators of shell and kernel separators need to be trained properly on how to use, maintain, and clean the machines. This will ensure that they are handled carefully and correctly and improve the lifespan of the unit.
Regular maintenance will make sure the separator functions smoothly and has a long life of use.
Industries involved in processing various nuts predominantly utilize kernel and shell separators for separating the kernels from the broken shells. Below are some typical applications and usage scenarios of kernel and shell separators.
Food processing industry
In the food processing industry, kernel and shell separators are mostly used to extract valuable nut products like almonds, walnuts, pecans, and cashews. Again, the separators are helpful for manufacturers in the dairy industry. They help separate valuable dairy products like milk and cheese from inedible chucks such as dairy equipment plastic.
Pharmaceutical industry
Pharmaceutical manufacturers use kernel and shell separators to extract various seed-based medicinal drugs. These include the sepals of drugs such as the drugs from grape seeds and others. Unwanted shells are separated using the separator, and the valuable medicinal kernels are refined further for use in the medical industry.
Cosmetics industry
Cosmetic companies use shell and kernel separatrs to separate kernels with cosmetic application. For instance, cosmetic companies may utilize apricot kernel and shell separators to separate the apricot seeds. The apricot seeds are useful in formulating exfoliating creams and scrubs.
Research and development
In the research and development labs, kernel and shell separators are used by nut, seed, and fruit research organizations. The aim is to carry qualitative analysis and genetic studies. In such cases, small-scale laboratory models of kernel and shell separators are employed.
Before buying a kernel separator machine, it is essential to check the factors highlighted below.
Productivity
When purchasing a separator, it's crucial first to examine the amount of work required and then select a separator model whose productivity matches the volume of work needed. This can help save costs and ensure efficiency.
Quality of the final product
When choosing a separator, it's essential to consider the quality of the final product it produces. The ultimate goal of using the separator is to have a desirable end product, and investing in a separator that achieves this can significantly impact success.
Durability
Consider the durability of the separator when selecting it. A durable separator can provide long-term service, reducing the need for frequent replacements and repairs.
Maintenance services and cost
When selecting a separator, it's essential to consider the maintenance services required and the cost associated. Some separators may incur high maintenance costs due to specialized servicing needs, while others may be more straightforward and less expensive to maintain.
Technology
It's essential to consider the technology used in the separator when making a choice. Different separators employ various technologies, each with its benefits and limitations.
Size and dimension
When selecting a separator, it's crucial to consider its size and dimensions. The dimensions of the separator must correspond to the space allocated for it in the working environment.
Energy efficiency
When selecting a separator, consider its energy efficiency. Energy-efficient separators can lead to significant energy savings over time, benefiting both the environment and cost-effectiveness.
Q1. How does a kernel and shell separator work?
A1. The separator works by exploiting the differences in size, shape, and density between the kernel and shell fragments. Typically, the process involves feeding the material into the machine, where it will be divided into different grades by vibrating screens or air classifiers. Lastly, the separated materials will be collected in different containers.
Q2. What are the advantages of kernel and shell separators?
A2. Such separators can improve the quality of products by reducing the quantity of undesirable kernel and shell fragments. They can also enhance the yield by ensuring that a maximum number of intact kernels are recovered. Furthermore, the separators can save labor costs by automating the separation process.
Q3. What are the types of kernel and shell separators?
A3. There are air classifiers and vibrating screen separators, which are usually used for separating the nuts' kernels and shells. Also, there are separators specifically designed for processing palm nuts, such as the palm kernel and shell separator. Furthermore, some separators are incorporated into a larger processing line, such as those combined with grinders, extractors and filters.
