How to process white sweet potato starch

To process refined white starch with sweet potato, sweet potato varieties with high starch content must be used. The specific methods are as follows: 1. Select the sweet potato varieties with high starch rate. There are many types of sweet potato, and the starch type should be selected for making starch. According to my local processing practices, it is better to choose "Lu Xuan No. 1", "a nest of red", "Victory No. 100", "Meiying No. 1", "868" and other red-skinned starch-type fine varieties. These varieties are grown on sandy soil, hillsides, hills, and low-lying clays. The extraction rate is generally around 18%-25%. Second, choose advanced processing machinery. There are many different types of potato processing machinery on the market. According to the size of the processing and the amount of processing, the potato refiner, slag separator, which has good mechanical properties, high degree of automation, high starch yield, robustness, strong applicability, simple operation, and convenient use, are selected. Throwing pieces automatically over the machine, the bending roller automatically over the machine and other machinery. Third, the production of starch sedimentation tank. Depending on the size of the processing, the amount, the amount of cement available, it can also be bricked (with plastic sheeting inside). It can be used to make a starch pool with a machine or a pool or a pool, or a starch sedimentation tank for refining starch. Leave the outlet on the pool side. Fourth, timely harvest. The early harvest of sweet potatoes will reduce the rate of starch production, and late harvest of frozen sweet potatoes will also reduce the starch rate. Generally, it is appropriate to harvest in the middle of cold frost and frost, and the harvest should be harvested in different places according to the geographical location and climate conditions. The harvested sweet potatoes should be cleaned and processed in time, and not stored for a long time to prevent saccharification to reduce the starch rate. Do not reprocess the sweet potato stored in the pit. Fifth, clean potato chips. Before cleaning, remove diseased potatoes, rotten potatoes, and sand and gravel to prevent mixing in the potatoes and causing mechanical damage. When cleaning, the potato pieces can be washed on the cement platform with water, and the potato pieces can also be cleaned in the cement pool and the large cylinder. Soil mixing affects starch quality. Six, grinding refining. Use 80-90 mesh nylon screen. The water supply should be sufficient. After the smashed and filtered slag is separated, the slurry flows into the large pool and precipitates. Seven, starch separation. The slurry that has flowed into the large pool, after a natural precipitation of 6-7 hours, is discharged from the water outlet to leave the starch. VIII. Fine sedimentation in a small pond. In the large pool, after several times of processing and depositing the accumulated starch, after the small hair powder eyes were found, the machine was replaced with a 100-120 mesh nylon screen. In the small pond, drowning water within 6-7 hours after being deposited in a large pond, about 1/3 of the volume of the small pond, and then adding the starch from the large pool to the water and re-grinding into the pool, precipitate for 24-36 hours. After the precipitation, the above drowning water and surface yellow viscous material are released. The rest is pure white starch. If there is dirt in the bottom layer of the starch in the tank, use a spatula to scoop it out and re-filter it. Nine, timely drying. Koike's starch can be loaded into a powder pocket made of 120 mesh nylon mesh 1 meter square, and then hung up. After parking, the slurry is filtered out, dried in time and stored in bags.

Pumpkin Seed kernel

Pumpkin seed kernels grow in Northwest and Northeast origin of China and have different types of seeds. Shine Skin Pumpkin Seed kernel, Snow White Pumpkin Seed kernel and GWS (Grown without shell) are three main type of Pumpkin Seed Kernel that commonly see in the market. Pumpkin seed kernel is also known as pepita. It is the edible seed of a pumpkin or certain other cultivars of squash. The seeds are typically rather flat and asymmetrically oval, and green in color and may have a white outer hull. Some cultivars are hulless, and are grown only for their seed. Our company has one production line specially process all kind of pumpkin seed kernel.
