Drying is an important industrial process. Various temperature levels and drying principles are applied in industrial dryers. The most common dryer type is one in which air is heated with steam, gas or hot water and then circulated over the wet product. As the air picks up moisture from the wet product, its humidity increases and the energy contained in this stream may make it a useful heat source. Standard procedure is to exhaust this humid air or dehumidify it. With a heat pump, heat can be extracted from the humid air. The air is cooled down and dehumidified. The extracted heat can be increased in temperature and can be used to heat the dryer.
Thus, the use of a heat pump serves two purposes – heat the dryer and dehumidify and recirculate air. Heat pump assisted drying can give high efficiencies because of this.
Pasteurization For pasteurization a product needs to be heated above 70 °C. Afterwards the product is cooled down. The product temperature thus varies from cold before pasteurization to hot during pasteurization and back to cold again after pasteurization. In most pasteurization processes heat exchange between the cold and hot product flow is already implemented. The cold product before pasteurization is used to pre-cool the product directly after pasteurization, or looking at it the other way around: the hot product is used to pre-heat the cold product. In addition to this extra heating and cooling are needed for pasteurization. This is normally provided by, for example, steam injection and a flow of chilled water. A heat pump might be the ideal solution to extract heat from the product that needs to be cooled and supply this heat at a higher temperature to the product that needs to reach pasteurization temperature.
Cleaning and Sanitization
All milking equipment, lines, and utensil surfaces that come into contact with milk or dirt or manure must be thoroughly cleaned and sanitized before the next milking. Bulk milk tanks also must be cleaned after each milk pickup. and sanitized before the next milking. The purpose of cleaning is to remove milk soils, organic and mineral solids that form on equipment surfaces after the milk is removed. The purpose of sanitizing is to kill residual microorganisms present on these surfaces immediately prior to milking. Inadequate or improper cleaning or sanitizing or both allows bacteria to remain on equipment surfaces and to grow and multiply. Bulk hot water used for this applications.
- Inorganic salt manufacture including sodium salt sulfate, boric acid, sodium carbonate can use heat pumps in concentrating salt solutions.
- Treatment of effluent process by concentrating waste streams to reduce hydraulic load waste treatment facilities.

- Pharmaceuticals manufacture can use in process water heating.
- Pulp manufacturing can use in process like concentration of black liquor.
- Paper manufacturing in process like water heating and flash-steam recovery.
- Lumber manufacturing in product drying.
Food and beverages
- Activity of manufactures of alcohol like beer brewing, in processes like concentrating waste beer.
- Wet corn milling/corn syrup manufactures can use in concentrating steep water and syrup.
- In Dairy products or Juice manufactures in concentrating their liquid products.
- Nuclear power stations, it can be used in concentrating radioactive waste and cooling tower blow down.
- Textiles Industries, processes like wash water heating, space heating and concentration of dilute dope stream.
- Electroplating industries use in heating process solutions and concentrating effluents.
In other activities like solvent recovery, district heating and steam-stripping of process streams and waste water they are highly used.
