The vacuum cooker agitator is a mechanical system designed to force the circulation of cooked mass within vertical reactors in the sugar and alcohol sector. The application of Mechanical Circulator Agitators is essential to optimize the sugar cooking process, ensuring efficient thermal exchange and homogeneity of the crystals even with the sudden changes in viscosity that occur during operation.
In the complex environment of power plants, the industrial vertical cooker presents unique challenges due to irregular feeding and dependence on the quality of the raw material. To overcome these barriers, the forced agitation system acts directly to reduce cooking time, avoiding scale in the calender tubes and promoting superior honey exhaustion, which results in a much higher volumetric yield for the plant.
Agimix has been in the industrial agitation and mixing solutions market for 15 years, supplying agitators, tanks, reactors, mixers, dispersers and related equipment for the industry in general. It is important to highlight that, for large plants, we exclusively supply the mechanical circulation system, which is custom-installed in the vacuum cooker that the customer already has, ensuring perfect integration and operational robustness without the need to change the main vessel.
The Mechanical Circulator Agitators were developed to optimize the sugar cooking process, drastically reducing the dough cycle time.
Forced circulation improves the heat transfer coefficient in the tubes, reducing steam consumption and preventing localized overheating.
Designed to withstand sudden changes in viscosity, the equipment prevents excessive vibrations and protects the mechanical integrity of the vertical reactor.
It promotes more efficient depletion of the mother liquor, resulting in greater recovery of sugar crystals and greater financial profitability for the plant.
Each mechanical circulation system is sized specifically for the geometry of the customer's existing tank, ensuring the best possible hydrodynamics.
These specifications are not fixed for every piece of equipment: they represent possibilities available on some of the listed models. Contact our sales team to confirm the information and the ideal configuration for your operation.

Direct answers to the most common questions about this equipment and its application.
The vacuum cooker agitator is a mechanical piece of equipment coupled to the reactor to force the movement of the cooked dough. It serves to homogenize the mixture and improve thermal exchange during sugar crystallization in the sugar and alcohol sector.
The Mechanical Circulator Agitators were developed to optimize the sugar cooking process by eliminating dead zones in the tank. This ensures that the crystals grow evenly, even with the irregular feed typical of plants.
No, Agimix only supplies the agitation and circulation system to be installed in the tank that the plant already has. Our own reservoirs range up to 10,000 liters, which is why, in large-scale sugar and ethanol projects, we work exclusively with mechanical mixing technology.
The main challenge is dealing with sudden changes in viscosity in a short period of time. The equipment needs a robust gear motor and an efficient impeller to keep the mass circulating without overloading the electrical or mechanical system.
Forced circulation increases the velocity of the fluid in the tubes, which significantly increases the heat exchange coefficient. This reduces the mass boiling time and reduces the overall steam consumption of the industrial plant.
Generally, the parts in contact with the product are manufactured in 304 or 316L stainless steel, guaranteeing resistance to corrosion and abrasion. The choice of exact material depends on the project specifications and the chemical aggressiveness of the cooked dough.
Yes, the retrofit project is very common and highly recommended in the sugar and alcohol sector. Our engineering sizes the shaft, impeller and drive to perfectly adapt to the geometry and nozzles of the cooker already operating in your plant.
The quality of the sugarcane alters the rheology of the mass, requiring the mechanical circulator to have an adequate torque reserve to operate in adverse conditions. Correct sizing guarantees continuous operational stability, regardless of crop variations.
