Our walnuts originated from Xinjiang production area, own walnut farm more than 20,000 acres, the main varieties are 185 paper walnut, Xin'er walnut, Xinfeng walnut and 33 walnuts and so on. Xinjiang walnuts at the end of August each year, the natural cracking of the green skin, peeling down the tree. Shelled walnuts are processed on-site in Aksu, Xinjiang for drying, screening and packaging. Subsequently, the shelled walnuts are transported to Shanxi Pengda Zhenglong Food Co., Ltd. where the factory commissions more than 1,000 local household farmers to process the walnuts, all peeling the shells manually. Afterwards, machinery combined with manual labour to complete the subsequent screening, picking, packaging and shipping.
As a professional and experienced walnut supplier, we have always been at the forefront of the industry, constantly introducing advanced technology, and are committed to providing customers with the highest quality walnut products. In the screening process, which is a key part of walnut processing, we have innovatively applied AI technology, which has greatly improved the accuracy and efficiency of screening.
Our AI screening device is able to accurately distinguish between 10 different colours and sizes of walnut kernels. Using a high-resolution camera and advanced image recognition algorithms, the device is able to capture the subtle characteristics of walnuts, whether it's a difference in colour or a hair's breadth in size, and accurately identify them.
In terms of processing efficiency, each colour sorter can process about 1 ton of walnut kernels in one day. This efficient processing capacity not only ensures that we can quickly process a large amount of walnut raw materials, but also ensures that each batch of walnut kernels is strictly screened and the quality is stable and reliable.
Our entire walnut processing process, from the source planting in the Xinjiang production area, to the preliminary processing in Aksu, to the fine processing in the Shanxi plant, each step is carefully controlled.
In order to ensure that each walnut kernel meets our strict quality standards, after being screened by the AI colour sorter, we will arrange professional workers to manually select the kernels again on the conveyor belt. During the manual selection process, workers follow a standardised operating procedure to ensure that overall production efficiency is not compromised and product quality is maximised.
For the removal of impurities, we use advanced X-ray machines and small-hole filters, which scan walnuts in all directions using X-rays that penetrate objects. Using specialised image analysis software, operators are able to accurately identify and mark walnut kernels containing impurities, which are then removed from the production line by an automatic rejection device.
The small-hole filter separates the walnuts from the impurities based on the difference in size. It is equipped with a precisely designed screen with tried-and-tested and optimised pore sizes to ensure that only walnut kernels of the correct size pass through, while broken walnuts and other impurities that do not correspond to the correct size are rejected. This double-guarantee impurity removal method ensures that our walnut kernel products are pure and free of impurities to the greatest extent possible.
In order to further guarantee the quality and supply stability of our walnut products, we have set up large warehouses in Xinjiang and Shanxi, and have constructed a perfect storage system. The warehouse in Xinjiang production area is close to the walnut planting bases and primary processing areas, which enables us to store the walnuts quickly after harvesting and minimise the transportation time and loss. The warehouse in Shanxi facilitates the secondary processing and subsequent distribution of products.
Both warehouses are equipped with advanced cold storage facilities. These warehouses are equipped with an intelligent temperature control system, which can precisely control the temperature in the most suitable zone for walnut kernel preservation, and the humidity is also strictly regulated, which effectively inhibits the oxidation and deterioration of walnut kernels and ensures that the walnuts still maintain their freshness and richness of nutrients in the process of long-time storage as well.
Our shipping process is rigorous and standardised, and each step is carefully designed and strictly executed. In the loading process, we arrange professionally trained workers to load the products manually. They are familiar with all kinds of packaging materials and product characteristics, and are able to avoid product damage caused by improper loading and unloading according to different order requirements.
In terms of packaging, we adopt advanced vacuum packaging technology. The vacuum packaging machine can accurately extract the air inside the package to form a low-oxygen environment, which effectively extends the shelf life of walnut kernels. After packaging, the product passes through the conveyor to the sealing section, where the sealing equipment is strictly calibrated to ensure the safety of the product during transport.
In addition, we understand that different customers have different needs, so we can customise packaging according to customer requirements. We have a professional team to provide full support and services in packaging design, incorporating customer's brand elements, specific patterns or text messages. From creative conception to design and layout, to actual production, we strive to achieve perfection in every step of the process, creating unique packaging solutions for our customers to meet the diversified needs of the market.
