Märkäprosessi

Märkäprosessi, often translated as wet process, refers to a manufacturing or chemical processing method that involves the use of a liquid medium, typically water, to facilitate or carry out a particular operation. This contrasts with dry processes, which operate without significant liquid involvement.

In various industries, wet processes are employed for tasks such as dissolution, suspension, extraction, purification, and coating. For example, in the food industry, wet processing might involve washing fruits and vegetables, or extracting oils from seeds using solvents. In the mining industry, wet milling is a common method for grinding ores in the presence of water to create a slurry for further processing. The pharmaceutical sector also utilizes wet granulation as a technique to improve the flowability and compressibility of powders for tablet manufacturing.

The advantages of wet processes can include better temperature control, improved mixing, and the ability to handle fine particles more effectively than some dry methods. However, they also often involve challenges related to liquid handling, waste disposal, and drying the final product, which can add complexity and cost to the overall operation. The choice between a wet and dry process depends heavily on the specific material properties, desired product characteristics, and economic considerations of the application.
