Maize flour screening plays an important role in removing unwanted particles at different stages of processing. Each stage is different in its requirement from fine sieving of maize kernels before the de-stoner to checking screening finished flour before packing.
For manufacturers, selecting the right sieving machine depends on the material, the impurities to be removed and the required production output. Galaxy Sivtek evaluates these requirements to recommend suitable screening solutions for the application.
A leading maize flour manufacturer in India needed to improve screening at two stages of its production process.
The first thing the company wanted to do was to eliminate small particles, such as sand, from the maize kernels prior to the de-stoner. It also required check screening of finished maize flour before packing to help remove contaminants and oversized particles.
The conventional sieves in the plant needed high maintenance and were not able to achieve the desired output.
Galaxy Sivtek asked for samples of maize kernels and flour to be sent to the laboratory for testing at their R&D department to understand application. The trials were very useful for the team to review the screening needs and then to suggest appropriate equipment options for each stage.
After conducting the sample tests successfully, Galaxy Sivtek recommended two machines to cater to the needs of the customer.
Linea Sivtek® was recommended as the fine sieving of maize before the de-stoner for the first stage of the process.
The maintenance requirement identified in the case study is an advantage and its enhanced screening area provides a high throughput. This made it suitable for the customer’s requirement to remove smaller impurities before the next processing step.
For the final screening stage, Super Sivtek® Separator was recommended for check screening the finished flour.
The case study describes the installation of a round vibro sifter before packing. The equipment was used to remove unwanted contaminants such as fibre or screws that could have been put in during manufacturing and oversized particles.
These two applications demonstrate why screening equipment should be selected according to the material and the purpose of each processing stage, rather than assuming one machine will meet every requirement.
Yes. The screening solution is a function of the application and the intended result.
Another method of screening is illustrated by Galaxy Sivtek’s centrifugal sifter screening process for maize flour. However, the suitability of a centrifugal sifter for a particular plant depends on factors such as material characteristics, required separation and production needs
Assessing these requirements helps manufacturers identify an appropriate screening configuration for their process.
According to the maize flour screening case study, the installation increased the customer’s plant capacity and resolved the screening problems previously experienced.
Application also brings out the importance of evaluating each screening requirement independently and making a recommendation for equipment based on the requirements of the process.
Each screening application is unique with its own requirements. Equipment selection is affected by the characteristics of the material, unwanted particles, required output and process conditions.
Galaxy Sivtek can provide you with various screening equipment and can evaluate the application requirements, and recommend the most appropriate screening equipment for maize flour processing.
