Cylindrical Heating Systems

IMS Cylindrical Heating Systems provide a unique solution which is best utilized for the continuous thermal processing of heat and shear sensitive, high viscosity, and multiphase materials that demand precise temperature control.

Planar Heating Systems

IMS Planar Heating and Drying Systems can offer a better alternative to conventional, re-circulated hot air dryers due to the best-in-class uniformity, efficiency and thermal processing they demonstrate in many industrial processes.

Cylindrical Heating Systems

Although an IMS CHS can be used for many product and process applications, including heating, cooking/gelation, pasteurization and sterilization, its specific benefits and economic advantages are best achieved when applied to heat or shear sensitive, high viscosity and multi-phase fluids.

Planar Heating Systems

An IMS Planar Heating System has advantages over conventional dryers in two areas of their design that are intrinsically inefficient: (1) pre-heating a product to evaporative temperature, and (2) removing water from products with relatively low overall moisture content.

Applications

Although an IMS CHS can be used for many product and process applications, including heating, cooking/gelation, pasteurization and sterilization, its specific benefits and economic advantages are best achieved when applied to heat or shear sensitive, high viscosity and multi-phase fluids as shown in the following examples:

  • An IMS CHS combines cool tube wall surfaces, fast product heating and short residence times to minimize fouling deposits, product degradation and production downtime.  A global petrochemical company replaced a steam heated shell-and-tube exchanger with an IMS unit and was able to reduce production downtime due to frequent blockage of heater tubes.  This resulted from the product experiencing long residence times and high tube wall temperatures requiring excessive downtime to drill the tubes and remove product build up.  The IMS CHS also reduced the company’s product formulation cost as the high viscosity polymeric resin required less catalyst than previously required.
  • Superior product quality with minimal color change and better nutrient retention and organoleptic properties have been achieved by a CHS installed in a vegetable processing facility.  The overall quality of test product from the IMS CHS compared far more favorably to test products obtained from other conventional heating technologies, which determined the decision to use continuous microwave  heating.
  • Product shelf-life of over two years with reduced storage and distribution costs are currently achieved by this food processor with all its shelf-stable pumpable vegetable products. This is possible with the IMS CHS technology as it is an excellent method for the thermal treatment of high and low acid food products, particularly when rapid deactivation of enzymes is important.
  • The center of particulate products may achieve higher temperature than the surrounding carrier fluid, due to volumetric heating enhancing the thermal process. This is particularly important to regulatory authorities when validating either pasteurization or sterilization processes for these products.
  • An IMS heater requires minimal formulation changes to achieve an even temperature distribution during heating. This is rarely the case with other electro-heating technologies, such as ohmic and radio frequency, that do not benefit from the advantages of volumetric heating. As this occurs from the center towards the tube wall, the result is an improvement in overall product quality and consistency of the formulation. This has been recognized by the Quality Assurance Department of a leading US processor of surimi and surimi seafood products who replaced the traditional water bath test for its shear sensitive products with an IMS heating system. The cooking and gelation characteristics of the IMS test products are far closer to those experienced in production than the water bath test.
  • IMS CHS technology can produce new products that conventional heaters cannot.  A New York based company is using an IMS heater for the Microwave Assisted Extraction (MAE) of plant protein cells to maximize yield and product quality of its biopharmaceutical products.  An Alabama based organization also uses MAE with ionic liquids to maximize the extraction of biochemicals from crustacean waste products.  As the pharmaceutical industry changes from batch production to continuous, IMS CHS technology is expected to play an increasing role in the rapid sterilization of high-value, heat sensitive intravenous and other fluids.
  • Combined with other thermal technologies, IMS CHS designs can optimize final heater retrofits or new production lines.  Optimum payback is obtained by utilizing a CHS in a process application that is difficult to control or clean when using traditional hot surface heat exchangers.
  • Operating and maintenance costs can be reduced as the IMS CHS has no moving parts.  The non-intrusive heating process is easy to control, clean-in-place and inspect when required.
