Large-Scale Potato Starch Processing Machinery Recommendation

-

For large-scale potato starch processing, wet process technology remains the industry standard for achieving high starch yield, purity, and processing efficiency. This method, which separates starch granules from potato cells in a water-based system, is particularly suited for automated processing lines handling 20 tons or more of raw potatoes daily. Below is an overview of the essential equipment required for a fully integrated, large-scale potato starch processing line.

Essential Equipment for an Automated Potato Starch Wet Process Line

1. Raw Material Handling and Washing Unit

Primary Function: Removal of soil, stones, and organic impurities from raw potatoes.

Key Equipment:

Dry Sieve: Handle large impurities like soil, stones, leaves on raw potatoes.

Rotary Washer: Provide thorough scrubbing and washing potatoes through rotational movement in a water medium.

2. Cutting and Grinding Unit

Primary Function: Disintegration of potato tissue to release starch granules.

Key Equipment:

Cutting Machine: Cut potatoes into small pieces convenient for further grinding

High-Capacity Raspers: Feature specially designed saw blades to create uniform pulp consistency while maximizing potato starch release.

3. Starch Extraction and Separation Unit

Primary Function: Separation of potato starch milk from fibrous pulp.

Key Equipment:

Centrifugal Sieve: Multi-stage screening systems that separate potato starch from fiber through counter-current washing principles.

4. Starch Purification Unit

Primary Function: Further removal of residual impurities like proteins and cell saps and other soluble components.

Key Equipment:

Desanding Cyclones: Specifically designed for removing mineral impurities.

Multi-Stage Hydrocyclone Stations: Provide efficient washing and concentration of starch. Refine starch milk by removing proteins and fine impurities through density-based separation.

5. Dewatering Unit

Primary Function: Reduction of moisture content in purified potato starch slurry.

Key Equipment:

Vacuum Filtration Units: Employ vacuum pressure to extract water from starch slurry, forming a moist cake with reduced moisture content of 40%.

6. Drying System

Primary Function: Final moisture reduction to meet commercial standards.

Key Equipment:

Flash Dryer: Utilize rapid hot air exposure to efficiently dry starch particles without compromising quality. Normally the moisture of dry potato starch is about 12-14%

Cooling Conveyors: Stabilize potato starch temperature post-drying.

7. Finishing and Packaging Unit

Primary Function: Preparation of qualified potato starch for storage and distribution.

Key Equipment:

Milling and Sieving Systems: Ensure uniform particle size distribution.

Automated Packaging Machines: Provide precise weighing and packaging operations.

Technical Advantages of Potato Starch Wet Process Technology

Enhanced Starch Recovery: Achieves superior extraction rates through comprehensive cell rupture and counter-current washing.

Consistent Quality Output: Multi-stage refining ensures high purity and uniform product characteristics.

Processing Efficiency: Continuous operation capability supports high-volume throughput requirements.

Resource Optimization: Closed-water systems minimize fresh water consumption through sophisticated recycling.

The wet process technology, incorporating specialized equipment from initial washing through final drying, represents the optimal solution for large-scale potato starch processing. Tell us your capacity, Henan Jinrui's engineers will design a tailed equipment design!

Cassava Production Guide in the Philippines

-
Image
  Cassava is a vital crop in the Philippines, serving as a primary source of food and income for many farmers. This guide provides essential information on cassava production, include planting, harvesting and processing, to help Filipino farmers enhance their yield and profitability. Cassava tubers Climate and Soil Requirements: Cassava thrives in tropical and subtropical climates. It prefers well-drained, sandy loam to clay loam soils with a pH range of 5.5 to 6.5. Variety Selection: Choose varieties that are high-yielding, disease-resistant, and suitable for the local climate. Recommended varieties in the Philippines include CIAT 30576, TMS 30572, and KM 94. Seed Preparation and Planting: Use healthy, disease-free cuttings for planting. Cuttings should be about 20-30 cm long with at least 5-7 nodes. Plant cuttings vertically or at a 45-degree angle, ensuring that at least two nodes are buried in the soil. Land Preparation: Plow and harrow...
