Advantages of KMA Systems in Different Food Processing Industries

The systems and solutions offered by KMA present many advantages for different food processing applications. Specifically, we will explore their applications for smokehouse use, for frying and cooking applications, for spray drying, food drying, and roasting. Each of these key food processing industries will be discussed objectively and analytically to highlight the distinct benefits of using KMA in these, and other industrial food processing set-ups.

KMA Systems in Smokehouses

Smokehouses in the food processing industry face challenges related to the emission of strong odors and fumes, which can cause problems for nearby residential areas and necessitate environmental protection measures. To address these challenges, filtration systems are essential in smokehouse operations. The following list provides the step-by-step process of how smokehouse filtration works:

  1. Filtration systems capture and remove odorous substances emitted during the smoking process, preventing them from spreading to neighboring areas.
  2. These systems use various filter elements, such as electrostatic particles filters and waste air scrubbers, to effectively separate aerosol particles (liquid droplets) and eliminate odor.
  3. The filtration process ensures that only clean air is released into the environment, reducing pollution and maintaining a pleasant atmosphere.

The KMA Quality Effect on Frying and Cooking

Filtration systems have a significant role in maintaining clean air quality during frying and cooking processes. Industrial air filtration systems are essential for removing particulate matter, odors, and harmful emissions generated during these production processes. These systems ensure that the surrounding environment remains free from pollutants and that workers are not exposed to hazardous substances.

The use of efficient filtration systems in cooking facilities helps control the release of smoke, grease, and other byproducts into the atmosphere. By incorporating advanced technologies such as electrostatic precipitators and activated carbon filters, industrial air filtration systems effectively capture and remove contaminants from the exhaust air. This ensures not only compliance with emission regulations, but also promotes a healthy work environment. Implementing reliable filtration solutions in frying and cooking processes is crucial for achieving optimal air quality control and protecting both human health and the environment.

KMA Filters in Spray Drying

Spray drying is a process used in the food processing industry to convert liquid or semi-liquid materials into dry powders.

  1. KMA filters provide efficient and effective removal of particulate matter and odors generated during spray drying operations. These filters ensure that the exhaust air released from industrial food processing machines is clean and free from contaminants.
  2. Many food processing equipment manufacturers already rely on KMA to maintain high air quality standards in their facilities. The filters effectively capture and separate aerosol particles, preventing them from being released into the environment.
  3. By incorporating KMA into their drying equipment processes, companies can minimize environmental pollution and comply with emission regulations. The use of these filters also contributes to energy conservation and cost savings, as they require less energy compared to conventional afterburning systems.
  4. Another important aspect to consider is hygienic product recovery. KMA has a customer who produces protein powder who saves a sizeable amount of operating costs every week thanks to the product recovery of the KMA system applied to his spray dryer. Another customer opted for KMA systems is their new production sites rather than using the existing systems recovered product.

KMA Filters in Food Drying
