[vc_row][vc_column][vc_column_text]The current situation of rising energy prices is a problem for industries across all sectors. Not only the increase in price itself but also the difficulty in forecasting these prices in the medium term. This directly influences process costs and generally, the additional cost cannot be directly passed on to the final product price. Selecting technologies is key in this process. We share a specific case of energy cost reduction in the dehydration processes of products through spray drying technology.<\/p>\n

When selecting technologies and designing industrial equipment and facilities to manufacture a specific product, estimates about the prices of each type of energy, manufacturing materials, raw materials, and land are considered, and based on these considerations, certain technologies are chosen. As sometimes happens with household appliances or transportation means, there are alternatives, some equipment is more economical, others are more expensive but consume less, or are more autonomous, take up less space, etc.<\/p>\n

From our experience in the stabilization processes of microorganisms, we tell you an example of dehydration technology with lower energy cost for dry powder products intended for animal feed or for agricultural applications.<\/p>\n

Spray drying as an alternative to freeze-drying<\/h2>\n

It is the case of spray drying technology as an alternative to freeze-drying to stabilize microorganisms as a dry powder product. As microorganisms are sensitive, when their viability is intended to be maintained, freeze-drying is traditionally used, since it is a dehydration technology that does not require temperature.<\/p>\n

In the case of probiotic microorganisms for food, nutritional supplements, bacteria, and yeasts, starter cultures for fermentation, it is generally the first option to consider. But there are increasingly more applications where the final product price is very relevant for the viability of the product, such as probiotic microorganisms and microalgae for animal feed or microorganisms for agricultural applications as biocontrol agents, so it is necessary to consider other possible lower energy cost technologies.<\/p>\n

The 5 advantages of spray drying for the dehydration of products<\/h2>\n

The spray drying technology for the stabilization of microorganisms while maintaining their viability and stability over time presents several advantages:<\/p>\n
