Factory Price Potato Starch Production Line Potato Starch Making Machinery for Sale
The description of potato starch production by potato starch processing equipment : 1. Potato cleaning and washing by potato starch processing equipment The washing conveyor and the special designed washing machine will washing the fresh potato and remove the solid impurity ,such as sand ,small stone during the transportation . 2. Potato wet milling by potato starch processing equipment The fresh potato is milled by the hammer mill with plenty of water to get the potato slurry. The purpose of the milling process is disruption of cell walls and release as much starch as possible for extracting potato starch . 3. Starch extraction by potato starch processing equipment The centrifugal sieves is used to separate the starch milk and the fiber for starch extraction . 4. Starch milk refining by potato starch processing equipment For making high quality potato starch , raw starch milk will be purified in the refining process. This involves the removal of small fibers from the starch milk and then the removal of juice water and starch milk condensation. For this purpose, the hydrocyclones are commonly used. Refining and concentration starch milk by hydro cyclones is the advanced technology in nowadays. 5. Dewatering starch milk by potato starch processing equipment Dewatering starch milk is to remove the excess water by rotary vacuum filter, after dewatering , the wet potato starch with moisture content around 38% . 6. Starch drying by potato starch processing equipment The potato starch drying machine will dry the wet starch with hot air in few seconds. Then, the starch is separated from hot air in cyclones. Due to short time of high temperature drying and intensive water evaporation from the starch granules, its surface is heated only to 40 °C. The potato starch after drying with moisture content around 13% .

Fresh sweet potato tubers will be washed after harvesting from the farm. Concerned it has big tubers, will adopt 2 stages cleaning machine(dry sieve and paddle washer)to get a better cleaning effect.
Then it will be grated, separated fibers, desanding, separated proteins, and removed moisture. The processing process is the key part of the whole process, it can decide the final starch quality and yield. From the grating step, there are cutting machines, rasper machines, hammer mills, and grater can choose to get different grating rates. The rasper machine grating rate is highest can is 96% compared to others. A higher grating rate means can try our best to extract starch as much as possible.
Sweet potato starch extraction machines separating machines
In fiber sieves, protein sieves also have different machines that can be chosen according to the buyer’s requirements. There are fine fiber sieves, centrifuge sieves, and hydrocyclone stations that can choose to get different separating rates. After processing moisture content will be around 40%, then dewatering by vacuum filter and drying by flash dryer, and sieving.
Sweet potato starch extraction machines drying machines
As one of the professional sweet potato starch machine suppliers in China, Henan Jinrui Food Company can provide different capacity sweet potato starch extraction machines from 5-ton tubers input to 40tons input per hour. After the buyer orders the plant, we also can provide factory drawings, and machine layout drawings to guide the factory building.
Recently we delivered a 5tons per hour sweet potato starch extraction machine plant in north China and the engineer installed the machine on site. If you also have an interest in investing potato starch project or cassava project, we are welcome to get your inquiry.
