Low temperature drying technologies

The objective of the study is to identify solutions for low-temperature drying technologies in the Food, Beverage & Flavor industries and technologies existing commercially today that sit in the space between the technical needs and equipment cost + operating cost of spray drying and freeze drying.

Both spray drying and drum drying employ heat which can be problematic for heat-sensitive materials (e.g. flavor change, flavor loss) and drive other undesirable reactions (e.g. simple sugar Maillard reaction, caramelization, color degradation, etc.). Therefore a solution that exhibits low temperature is ideal for industrial application in foods.

Freeze drying provides some good features-
  • A fine job of minimizing or eliminating thermal damage or further reactions
  • Provide limited encapsulation or protection
  • Higher equipment costs
  • Operating costs
  • Require milling which results in irregular particles and disruption of whatever dried matrix was created
  • Long production cycle

What we did

Our report provides a detailed answer to the following questions and it was divided into two phases:

Phase 1
  • What are the different approaches for low-temperature drying in the Food, Beverage & Flavor industries?
  • What are the different approaches for low-temperature drying in the Food, Beverage & Flavor industries?
  • What are the major approaches used in the market? [Key parameters for comparison include technical performance, operating cost, equipment cost, capacity, etc.]
  • What are the various approaches for the efficient drying of heat-sensitive materials? What technologies provide greater encapsulation efficiency for high-volatile components?
  • What problems and solutions are associated with low-temperature drying? What technologies are the market players using to dry food & flavor at low temperature?
Phase 2
Phase 2 was a business case study that was executed on the top two recommendations from Phase 1 and will answer the following question:
  • Brief Introduction to the business opportunity
  • Profitability earn by business opportunity
  • Opportunity description
  • Technology summary
  • Key advantages of the technology
  • Key benefits of business opportunity
  • Comparative analysis of selected business opportunities, e.g. SWOT analysis
  • Future growth of the company based on business opportunity

Project Timeline: The project was executed and delivered in 10 weeks.
