Cassava Processing Machinery for High-Quality Polvilho in Brazil

Brazil is a leading producer of cassava (mandioca/aipim) and its derivatives, including polvilho (cassava starch, both sweet—polvilho doce—and sour—polvilho azedo). To produce high-quality polvilho, efficient and modern cassava processing machinery is essential. Below are key machinery and steps involved in the process:

1. Cassava Cleaning & Washing Machinery

Purpose: Remove dirt, sand, and leaves.

Machinery:

Dry sieve(for removing soils, mud, and leaves)

Paddle washers (high-capacity water spray systems).

2. Cassava Grating/Rasping Machines

Purpose: Break down cassava roots into pulp for polvilho extraction.

Machinery:

Cassava Cutter ( with durable 4Cr13 rhombus blades for pieces production.)

High-speed raspers (with stainless steel saw blades for fine grating).

3. Polvilho Extraction (Sieving& Refining)

Purpose: Separate cassava starch from fibrous pulp.

Machinery:

Centrifugal sieves (for fine filtration of polvilho milk).

Hydrocyclone systems (a unity of concentration, recycle, and refinery for purifying polvilho slurry).

4. Dewatering & Drying

Purpose: Reduce moisture for shelf-stable polvilho.

Machinery:

Peel centrifuges (for dewatering).

Flash dryers (negative pressure drying for getting qualified starch with 12%-14% moisture).

5. Sieving & Packaging

Purpose: Produce fine, uniform polvilho powder.

Machinery:

Sifter Sieve (for fine polvilho powder).

Automatic packaging machines (for 1kg, 5kg, 25kg bags).
