Extraction of starch from potato procedure

Date:May 21, 2018/ Industry news/ Chat online

The extraction of starch from potato procedure can be mainly divided into three procedures: release the starch form potatoes by rasper; washing starch slurry by centrifuge sieve and fine fibre sieve; cleaning starch liquid concentration and purification by disc seperator and hydrocyclone station. This three procedures constitute the extraction process of starch from potatoes.

Next is the detail description of the extraction of starch from potato procedure:

Procedure One: starch release from potatoes. Rasper machine is the key equipment for potato starch release process, which directly affect the starch extraction rate or you can understand this as the raw material utilization. The machine can crush potatoes into small fine particles, to break potatoes fibers and cells entirely so that the starch can be released as much as possible. The extraction of starch from potato releasing rate can be more than 94%. Better extraction rate than others.

Procedure Two: starch slurry washing for removing impurities. Adopt Doing Company centrifuge sieve firstly to remove fiber and other larger impurities, then starch slurry goes through fine fibre sieve machine to filter fine fiber and smaller impurities out. At last, starch slurry will goes into desander machine to clean out sand and other sundries. This procedure function is to get clean starch slurry in the extraction of starch from potato procedure.

Procedure Three: concentration and purification. The procedure is used to remove protein and fats or others, Which Invisible creatures existed in the starch liquid, and at the same time it can concentrate starch liquid before dewatering process. Here DOING company adopt "Disc separator + Hydrocyclone station" technology, which increase the capacity and assure stable running of the equipment as well. Compared with just use hydrocyclone, this way more energy saciny and high efficiency, final potato starch products with higher quality.

To sum up, main machines used for the extraction of starch from potato procedure contain rasper, centrifuge sieve, fine fiber sieve, desander, disc separator and hydrocyclone station. DOING company can design and manufacturer complete potato starch production line based on actual requirements and budget. Of course, the extraction of starch from potato procedure demands machine is no problem, you also can contact us freely to discuss the extraction of starch from potato procedure.

Extraction of starch from potato procedure is the most important section for whole potato starch production line request high technology level, the starch extraction rate from potato decided the final starch yield and the utilization of raw materials, that's to say the extraction of starch from potato performance better, the raw material cost can saving more. This article is mainly to introduce the extraction of starch from potato procedure for you, also include the main equipments demanded and its function in each section.

After extraction of starch from potato procedure, next potato starch production procedure is starch liquid dewatering and drying, after this, we can complete the whole potato starch production. For another, it's worth to say that the most important machine in the extraction of starch from potato procedure is the rasper. Rasper is widely used in potato starch extraction process for crushing materials. This machine can crush the potatoes into very small particles, with the advantages of modern design, compact structure, high rotation speed, high crushing coefficient.  Rasper adopted to extraction starch from potato guarantee a high extraction rate of bound starch. It is a high-efficiency crushing machine developed by Doing Company in combination with advanced technology at home and abroad. Better than traditional hammer type crusher, this rasper make the starch extraction rate reach to 95%, highest using rate of raw materials, larger saving the raw materila cost.
