Enhance your spray drying profitability

Enhance your spray drying profitability

Food, pharmaceutical, and other production processes utilize spray drying to ensure product quality and consistency. These processes need to be reliable and efficient, regardless of climate conditions, where uncontrolled humidity and temperature can cause problems during the drying process.

Munters offers tailored dehumidification and heating solutions, which provide up to 40% increased production capacity, reduced energy consumption, and enhanced product quality. Munters’ spray drying solutions boost throughput and uptime – with a positive impacting on your profitability.

Dehumidification and efficient air heating are key for spray drying

Spray drying is a sensitive process, and it requires precise humidity and temperature control. Airborne moisture and undesirable humidity can have adverse effects on your production output:

  • Seasonal humidity variation can impact process time and quality.
  • Clumping and blockages occur when the air contains large levels of moisture, as powders and granules have a natural tendency to form lumps and clumps – especially prevalent in food and pharmaceutical processing.
  • Mold, fungi, and bacterial growth of all kinds can easily occur where the relative humidity is high. They can cause major damage to products, and could be a health risk to employees.
  • Condensation can result in pooling on surfaces where powders may get stuck and clump inside the machinery and/or drying chambers.
  • Corrosion of the spray drying equipment can reduce its efficiency and shorten its service life – driving up service and maintenance costs.

Indirect air heating is an essential step in the spray drying process. Traditional steam systems have high initial cost, low efficiency, and cannot provide higher supply temperatures. Munters’ VariMax IFRG, indirect recirculating gas heater, provides contaminant-free air – without increasing humidity levels – with supply temperatures up to 1000°F (538° C) and efficiency levels up to 98%.

Case studies

  • Sensus uses the Chicory root to produce Inulin

    Sensus uses the Chicory root to produce Inulin

    Based in Zwolle, the Netherlands, Sensus uses the Chicory root to produce Inulin, a sweetener used in the food industry.

    Sensus uses a spray drying process to convert the concentrated Inulin solution to powder. The product is quite glutinous and can easily foul the system if not carefully monitored. Munters and Sensus agreed on the patented quantum desiccant rotor to enhance Sensus spray drying production. With Munters proven technology, climate is no longer a variable, but a constant factor and production capacity has increased by 40%.

  • Finding the right heating solution for spray drying

    Finding the right heating solution for spray drying

    A creamery located in the Midwest required a replacement heater for one of their spray drying systems that processes powdered milk, and the new equipment needed to be manufactured in accordance with USDA guidelines, with very tight dimensional constraints in the installation site.

    The creamery chose a custom-manufactured Munters VariMax IFRG heater to replace its inefficient and oversized heater.

  • High efficiency heater in dairy spray drying

    High efficiency heater in dairy spray drying

    In the Quebec province of Canada, a local cheese producer required an indirect gas-fired heater for one of their systems that makes powdered cheese.

    This project required 42,000 standard cubic feet per minute (SCFM) of outdoor air to be heated to 400°F, despite an outdoor air temperature of -40°F.

    To provide these conditions, Munters VariMax IFRG natural gas-fired indirect heater with a Thermo-ZTM plate heat exchanger was installed.
