Hey there! I'm a supplier of paper shell walnuts, and I'm super excited to take you through the whole process of how these delicious nuts are processed. Paper shell walnuts are a real treat, known for their thin, easy-to-crack shells and rich, nutty flavor. So, let's dive right in!
Harvesting
The journey of paper shell walnuts starts in the orchard. These walnuts usually grow on walnut trees, and the harvesting time is crucial. We typically harvest them in the late summer or early fall when the outer husks turn from green to yellow-brown and start to split open. This indicates that the walnuts inside are fully matured.
We use a variety of methods to harvest the walnuts. Sometimes, we simply shake the trees gently, and the ripe walnuts fall to the ground. Other times, we use mechanical shakers that attach to the tree trunks and vibrate them, causing the walnuts to drop. Once they're on the ground, we gather them up using nets or by hand. It's a labor - intensive process, but it's worth it to get those high - quality walnuts.
Dehulling
After harvesting, the walnuts still have their outer husks on. These husks need to be removed as soon as possible because they can start to decompose and affect the quality of the nuts. We use dehulling machines for this task. The walnuts are fed into the machine, which has rotating drums or rubber rollers that rub against the husks, causing them to separate from the nuts.
The dehulled walnuts are then washed to get rid of any remaining debris or husk fragments. This washing process is really important as it helps to keep the walnuts clean and ready for the next stage of processing.
Drying
Once the walnuts are dehulled and washed, they need to be dried. Drying is essential to reduce the moisture content of the walnuts, which helps in preventing mold growth and extends their shelf life. We usually dry the walnuts in large, well - ventilated drying rooms or using specialized drying equipment.
The drying process takes several days, and we carefully monitor the temperature and humidity levels. The ideal temperature for drying paper shell walnuts is around 90 - 100°F (32 - 38°C). During this time, the walnuts lose a significant amount of moisture, and their flavor and texture become more concentrated. You can check out our Whole Walnuts in Shell which are dried to perfection.
Sorting
After drying, the walnuts go through a sorting process. We use a combination of mechanical sorters and manual inspection to separate the walnuts based on their size, shape, and quality. The mechanical sorters use screens and air jets to separate the walnuts by size. The larger and more uniform walnuts are usually considered to be of higher quality.
During the manual inspection, our workers carefully examine each walnut to check for any signs of damage, mold, or other defects. Only the best - looking walnuts make it through this stage. This ensures that when you buy our walnuts, you're getting the highest quality product.
Cracking
Now, let's talk about cracking the walnuts. Cracking is one of the most interesting parts of the processing. There are different methods for cracking paper shell walnuts. Some people prefer to crack them by hand, using a simple nutcracker. But in our processing facility, we use automated cracking machines.
These machines are designed to apply just the right amount of pressure to crack the thin shells of the paper shell walnuts without damaging the kernels inside. The cracked walnuts are then separated into shells and kernels. If you're interested in learning more about cracking walnuts, check out our guide on Cracking A Walnut.
Kernel Sorting
After cracking, the kernels need to be sorted again. This time, we separate the whole kernels from the broken pieces. Whole kernels are more valuable and are often preferred by consumers. We use another set of mechanical sorters and manual inspection for this process.
The whole kernels are carefully collected and packaged, while the broken pieces can be used for other products like walnut meal or walnut oil. This way, we make the most of every single walnut.
Packaging
Once the kernels are sorted, it's time for packaging. We package our paper shell walnut kernels in a variety of ways, depending on the customer's needs. We have small, consumer - sized packages for retail sales, as well as large bulk packages for food manufacturers and distributors.
The packaging is designed to protect the walnuts from moisture, light, and air, which can all affect their quality. We use high - quality, airtight packaging materials to ensure that the walnuts stay fresh and delicious for as long as possible. You can also check out our in Shell Jumbo Natural Walnuts which come in great packaging options.
Quality Control
Throughout the entire processing process, we have strict quality control measures in place. We test the walnuts at every stage to ensure that they meet our high standards. We check for things like moisture content, flavor, color, and the presence of any contaminants.
Our quality control team uses a variety of testing methods, including sensory evaluation, laboratory analysis, and microbiological testing. This way, we can guarantee that every batch of paper shell walnuts that leaves our facility is of the best quality.
Storage
After packaging, the walnuts are stored in a cool, dry place. Proper storage is essential to maintain their quality. We store our walnuts in temperature - controlled warehouses to prevent them from spoiling. The ideal storage temperature for walnuts is around 32 - 40°F (0 - 4°C).
When stored correctly, paper shell walnuts can last for several months or even up to a year. This allows us to supply our customers with fresh walnuts throughout the year.
