Sweet potato is a food with medicinal value that is many times more nutritious than rice and noodles. It also tastes very good, sweet and soft, and is suitable for all ages. Not only can it be made into a variety of delicacies, but it can also be processed into dried products, powder, biscuits and other products. It can even be used to make sugar and make wine, realizing the great development of the potato industry.

However, sweet potatoes come in different sizes and are covered with soil. How to handle and reprocess them is indeed a problem. After large-scale planting and harvesting or purchasing and centralized processing, the best solution for cleaning and sorting a large number of sweet potatoes is:

Cleaning system: Preliminary cleaning of the muddy sweet potato feed. Due to the rolling and soaking cleaning effects of bubbles in the water, the sweet potatoes roll up and down to clean the soil and pollutants on the potato pieces.

Brush cleaning machine: Deeply remove surface dirt. After preliminary treatment, the sweet potatoes enter the brush cleaning machine. The brush cleaning machine uses the brush to make rolling contact with the material, combined with the spray and scouring effect of the water gun above, to effectively remove dirt such as cortex and recessed mud on the surface of sweet potatoes.

Dryer: A tunnel dryer uses a centrifugal fan to absorb free hot air to form a circulation to dry the skin of sweet potatoes. Facilitate subsequent sorting and packaging work.

Since sweet potatoes come in different sizes, they are unsightly for direct sale and difficult to package and price. Sweet potatoes of different sizes are suitable for different production needs, so the choice of sorting machine is crucial. After sorting, the uniform size packaging is pleasing to the eye, and different specifications can also be selected for processing and production.

There are two main types of Fstsort sweet potato sorting machines. One is based on diameter size, and the other is optical sorting technology.

According to the diameter, there are fixed roller sorter and adjustable roller grader. The main difference between the two is that the fixed roller classifier can only be used to sort one product, while the adjustable roller classifier can sort different vegetables by adjusting different size standards. The capacity of both sorting machines is 6 tons per hour, and the sorting efficiency is high and accurate.

The sweet potato optical sorting line can intelligently identify the weight, size, shape, surface color, surface defects, etc. Compared with the roller classifier, the accuracy is higher and the throughput is larger.

These two different types of graders can be customized according to your output, warehouse area, and budget. If you want to know more, please send us an email.
