Cassava chips are in great demand all over the world for the production of ethanol. Global warming has placed a great demand on nations to minimize the emission of carbon dioxide and other toxic gases into the atmosphere. Ethanol is preferred because it does not emit Carbon Dioxide and contains oxygen. Most Premium Motor Spirit (PMS) used these days are either E-10 or E-20; these mean, 10 percent or 20 percent ethanol and 90 percent or 80 percent crude oil.  The essence is to minimize the presence of toxic gases which deplete the ozone layer.




(a)  Peeling:  Production of Cassava chips starts with the peeling of the cassava.  Peeling can be done mechanically or manually. Mechanical peelers peel as much as 2,400 – 2,500Kg per hour with a wastage rate of 30-40 percent while manual peeling does 22Kg per man hour and wastage of 20-25 percent.

Mechanical peelers are problematic because of the non-uniform nature of the cassava roots and the irregularity in size which make smooth peeling difficult. Also, the thickness of the skin, the texture and the strength of adhesion to the flesh of the tuber differ from specie to specie thereby making over-peeling and under-peeling possible. As a result of these problems, processors prefer manual peeling for now till the mechanical is perfected.


(b)  Washing: The peeled tubers are thoroughly washed to remove all dirt and sand that may adhere to them.

Export requirements insist that sand content should not be more than 2 percent.


(c)  Chipping: The washed tubers are carted to the chipping machines where they are chipped into small chips of about 1-2 centimeter thickness and 6-7 cm long. The sizes at times depend on the prescription of the order.


(d)  Drying: The wet chips are taken to the Rotary Dryer where they are dried to 12-14 percent moisture content.


(e)  Bagging: they are then weighed and bagged in 50kg polypropylene bags and stored.

4.         Production Capacity

1 (No) Chipping Machine produces

1.5 mt per hour or 25.5 mt per day

4 (No) Chipping Machines will produce

(25.5 mt x 4) = 102 mt per day


When dried in the Rotary Dryer at the ratio of 4:1, it comes to 25.5 mt/day.


The Plant can process, at least, 500-600 mt of Cassava chips per month.

If they want to increase to 1000 mt/ month, they increase the chippers to 8 and dryers to 2.  The plant capacity 25.5mt/day or 500 – 600mt/month.



The major raw material is cassava tubers. The daily capacity of the Plant is 25.5 mt and the monthly capacity is 663 mt. The daily raw material requirement is therefore (25.5 x 4) 102 mt of cassava tubers and the monthly requirement is (663 x 4) 2,652 mt. Four metric tons of wet chips will produce one MT of dried chips.




70 percent of the price will be paid at commissioning, 20 percent before delivery and installation and 10 percent after installation and test run.

Delivery Period:Delivery of machines shall be 13 weeks from the payment of the 70 percent and the clearing of the cheque.

Installation:Our technicians will install and test-run the plant. The client will provide the central gear switch of about 100 amps, motor starters and gear switches. We will prepare the bases for the machines but the client will provide the materials. It will take a maximum of 1-2 weeks if the electrical connections, water, power etc are in place. The client will take care of the accommodation, transportation, feeding etc of the technicians.


The production space should be about 200 square meters and the Rotary Dryer should be located in a well ventilated location.

Test run:About 5 tons of cassava tubers shall be required for the test run and it will be provided by the client.

Training and Commissioning: Your operators: Technician (1), Welder (1), Electrician (1) and Operators (3) will be trained during the installation. They are therefore supposed to participate in the installation and commissioning.

Warranties: 6 months for any production problem excluding changeable parts affected by aging, misuse and accidents.

Technical Support: Supply of spare parts at short notice, maintenance, quality control to ensure standard and consultancy services when needed.

Validity: This quotation is valid for 90 days from the date of submission after which the price may change.
