Paddle Mixer for Biogas Solid Substrates

Overview

The paddle mixer for solid substrates is an industrial equipment designed for the homogenization of agricultural waste and manure before feeding into biodigesters. This preliminary step guarantees a uniform mixture, an essential factor to optimize the anaerobic digestion process and maximize the generation of renewable energy in biogas plants.

Variation in biomass density and moisture can severely compromise the yield of the fermentation system. To solve this challenge, we apply advanced technologies such as Fluidized Zone Double Paddle and Axis Mixers, which promote the three-dimensional crossing of particles. This results in a perfectly integrated organic mass, preventing the formation of crusts or dead zones inside the main reactor.

With 15 years of experience in the industrial agitation and mixing solutions market, Agimix develops complete and tailored projects for the bioenergy sector. Depending on the characteristics of the waste, we can integrate the Arado Type Mixer for breaking agglomerates or the Ribbon Blender Mixers, available in capacities of 50 to 15,000 liters. It is important to highlight that we supply the high-performance mixing and preparation system for the food line, not manufacturing the large biodigestion tanks themselves.

Frequently asked questions

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

What is a biogas paddle mixer?

The biogas paddle mixer is an industrial piece of equipment focused on standardizing organic waste before biodigestion. It uses a rotating shaft with strategically positioned blades to create a continuous flow, transforming manure and agricultural waste into a homogeneous mass ready for the reactor.

Why homogenize the substrate before sending it to the biodigester?

prior homogenization of the substrate is vital to avoid phase separation and the formation of crusts inside the reactor. A well-prepared mixture facilitates the contact of microorganisms with organic matter, accelerating anaerobic fermentation and significantly increasing the volume of gas generated.

What types of waste can be processed in this equipment?

The system is highly versatile and processes agricultural waste, animal manure, straw and food waste. For materials with a high tendency to agglomerate, the Arado Type Mixer may be the most suitable solution due to its high shear and disaggregation capacity.

Does Agimix supply the complete biodigester tank?

No, Agimix is ​​a specialist in the substrate mixing and preparation system. We supply the industrial mixers that feed the process, with mixing chambers of up to 15,000 liters, but the customer must own or purchase large reservoirs and biodigestion ponds separately.

What is the difference between the paddle mixer and the Ribbon Blender?

The paddle mixer is ideal for denser and stickier materials, promoting a lifting and folding movement of the biomass. The Ribbon Blender Mixers use helical ribbons, being excellent for powders and granules, operating in volumes of 50 to 15,000 liters with custom manufacturing.

Does the equipment support the acidity and abrasiveness of organic waste?

Yes, our equipment is manufactured with materials with high mechanical and chemical resistance, such as AISI 304 or 316 stainless steel. This guarantees total protection against the severe corrosion typical of biogas, leachate and industrial effluent processing environments.

How is the paddle mixer activated?

The drive is carried out using a high-torque gearmotor, specifically designed to overcome the inertia of heavy and humid masses. This ensures a constant and controlled rotation, essential for standardizing the solid substrate without overloading the motor.

Does Agimix only sell the screw conveyor to feed the mixer?

We do not sell accessories or peripherals in isolation. Agimix provides complete projects and systems, integrating the main mixer with hoppers, screws and feeding systems, ensuring the perfect functioning of the entire biomass preparation line.
