Top entry agitator for the production of glue

“The tank is 20,000 liters, so imagine what the size of the agitator is!” With these words, director Johan Postma introduces the impressive, six-ton ​​weighting agitator that is currently located in the Jongia test center. The top-entry agitator is ordered by an United States based customer, engaged in the production of glue. In the past Jongia delivered smaller agitators at this customer site; the previous ordered agitator was used in a tank with a capacity of 5000 liters. The customer wishes to scale up the production process, so a larger agitator is needed.

A two-piece agitator

The liquid is kept moving continuously. The top entry agitator consists of two parts and both the inner as outer part contains agitator blades. The outer stirring element rotates counterclockwise and the inner, faster rotating stirring element rotates clockwise. In the central part the liquid is pressed down, on the outside it is pushed up, creating an evenly stirring process and an optimal product structure.

Mechanical seal

Sealing the rotating agitator shaft, at the opening of the tank, is an important part of the mixing technology applied by Jongia. Several seals are possible, depending on the temperature, the pressure in the tank and the speed at which the agitator rotates. The application and customer requirements on the production process are also taken into account. A special concentric mechanical seal has been used for this agitator. Both agitators are sealed by a single mechanical seal and the cooling / lubrication by a single locking system. Such a seal for double-acting stirrer(s) is optimal thanks to the special concentric mechanical seal, which guarantees a completely sterile mixing process.

Hygiene is increasingly important for many production processes. Outside air and dirt have no acces to the tank, even over time. In addition, leakage is excluded, nothing can leak out. A process solution with a mechanical seal is also recommended for the food industry, where hygiene is crucial.

Extensive process testing

The top entry agitator is extensively tested in our test center. The mechanical performance of the agitator is put to test and there is an evaluation of the final application in the production process. Thanks to our unique capacity in the test center testing is done vertical instead of horizontal: completely in accordance with the final application in the tank. After a succesful test run, the agitator is assembled for transportation towards the production site.

In-depth knowledge of process engineering was used to design this agitator. Anticipating on future process optimisations at the customer is also taken into account, by adjusting the rotational speed of both parts of the agitator on site. By offering this flexibility, the agitator is not only the best current solution, but also the best solution for the future.

Adding value for our customers

Jongia considers multiple aspects e.g. future investments, energy consumption and maintenance costs when developing an agitator. Jongia offers a longterm and sustainable solution, helping our customers to achieve the best possible process results with the lowest possible TCO.
