MILLTEC, as one of the market leaders, strives for continuous improvement- to serve customers better and to provide good value for their money. Disposal of rice husk is one of the major challenges faced by millers all over India. India produces around 25 million tons of rice husk every year. This rice husk ash when burnt in the boiler as fuel, generates ash known as rice husk ash (RHA). RHA is a great environmental threat but on a positive note, RHA contains 60% to 80% amorphous silica which has application in various industries.
As an expansion and diversification strategy, MILLTEC has introduced a high-efficiency precipitated silica extraction technology from rice husk ash. The equipment for the extraction plants are indigenously designed at MILLTEC. Silica is extracted based on batch processing, and MILLTEC offers millers batch processing plants of 2 tons per day silica extraction capacity. Along with silica, there are other by-products like carbon and sodium carbonate from RHA that are useful in various industries. This product is currently in its pilot phase.
Rice husk can be combusted in a boiler to generate steam for cogeneration and process requirement. The ash generated can be stored for silica extraction. The steam generated is utilised in a steam turbine which generates electricity. Electricity generated is consumed for mill requirements.
