Agitation Systems for 2nd Generation (2G) Bioethanol

Overview

The second generation (2G) bioethanol agitation systems are industrial mechanical assemblies designed to homogenize the lignocellulosic biomass during the critical steps of enzymatic hydrolysis and fermentation. By keeping sugarcane bagasse and other fibers in continuous suspension, this equipment accelerates the breakdown of cellulose molecules and maximizes biofuel production in plants.

The production of second generation ethanol requires strict control of the mixture, as the must has high viscosity and density. To meet this demand on a large scale, Agimix provides the complete agitation system to be installed in vats and large tanks that the customer already has. Our solutions include the Lateral/Horizontal Industrial Agitator, which offers high performance combined with ease of installation and maintenance, ensuring operational efficiency and process reliability.

To optimize mass transfer, the Vertical Agitator is developed with advanced engineering to maximize process efficiency, reducing energy consumption and ensuring high operational performance. When the process requires the disintegration of more difficult particles, we integrate the Bottom Emulsifier (Rotor, Stator), which works as an aid in breaking down lumps and emulsions in tanks and process reactors.

Agimix has been in the industrial agitation and mixing solutions market for 15 years, serving the industry in general with excellence. For pilot plants or smaller-scale processes (up to 10,000 liters), we manufacture the complete set with the Industrial Process Reactor, equipment that guarantees excellent productivity by combining cutting-edge technology for the sugar-energy sector.

Frequently asked questions

Direct answers to the most common questions about this equipment and its application.

What is a second generation bioethanol agitation system?

A 2G bioethanol agitation system is a mechanical assembly that homogenizes the mixture of water, enzymes and biomass, such as sugarcane bagasse. It is essential to ensure the efficiency of enzymatic hydrolysis, keeping the fibers in constant suspension for the action of the enzymes.

Does Agimix supply the large tanks for the fermentation of 2G ethanol in the plants?

No, Agimix only supplies the industrial agitation system to be installed in the vats and large tanks that the plant already has. We manufacture our own reservoirs and the Industrial Process Reactor only for volumes of up to 10,000 liters, ideal for pilot plants.

What is the best agitator for large volume fermentation vats?

The Industrial Lateral/Horizontal Agitator is often the best choice for large volumes in plants. It offers high performance combined with ease of installation on the side of the customer's tank, optimizing the mixing of dense fluids without the need for excessively long shafts.

How does the vertical shaker work in the production of biofuels?

The Vertical Agitator works by promoting an intense axial or radial flow, essential for the mass and heat transfer in the must. It is developed with advanced engineering to maximize efficiency and reduce energy consumption in the production process.

How to dissolve difficult lumps in lignocellulosic biomass?

To break down resistant agglomerations in the process, we use the Bottom Emulsifier (Rotor, Stator). It works as an excellent aid in breaking down lumps and emulsions, ensuring a fine and homogeneous mixture in tanks and reactors.

What materials are used in the manufacture of agitators for ethanol plants?

The equipment is predominantly manufactured in AISI 304 or 316L stainless steel, depending on the chemical aggressiveness and pH of the must. This guarantees high resistance to corrosion during the fermentation and hydrolysis stages.

Does agitation influence the yield of enzymatic hydrolysis?

Yes, adequate agitation is crucial because it increases direct contact between the enzymes and the exposed cellulose. A well-sized industrial mixer prevents fibers from settling at the bottom of the tank and drastically accelerates the conversion of biomass into fermentable sugars.

How are side agitators maintained in full vats?

Many models of side agitators can be equipped with mechanical locking systems, also known as shut-off. This allows the mechanical seal or gasket to be changed without the need to empty the plant tank, ensuring ease of maintenance and avoiding prolonged downtime.
