Drying and thickening
Drying and thickening are methods used within practically all industries:
– Food industry
– Fishing industry
– Feed industry
– Oil and Gas industry
– Timber industry
Drying is a process during which water is removed from a solid product.
– The water can be removed mechanically or by applying heat.
Mechanical removal of water is the cheapest method, however, it is only applicable down to a certain minimum water content. The remaining water must be extracted using heat (typically hot air). This is a very energy intensive process.
Inspissation is practically identical to drying, except the end product differs.
If the end product can be pumped, we talk about inspissation.
Drying is typically used in order to increase storage shelf life of organic matter by reducing the water content to below 10%, which prevents decay.
If the end product cannot be pumped, we talk about drying.
Thickening is used for concentrating a product, for instance with the purpose of reducing transportation costs. A product is often thickened, before it is dried.
