The crystallisation of your product means your product will form solid crystals from a liquid. Crystallisation takes place when you’re cooling the product. Every product has its own characteristics and starting temperature where crystallisation starts.
Why using a Ftherm machine Scraped Surface Heat Exchanger?
The Ftherm machine is ideal when, as part of a continuous process, you wish to crystallize your product.
When you use a Ftherm machine Scraped Surface Heat Exchanger, the product will be heated and cooled very efficient and homogeneous way, due to the continuous scraping and mixing principle. The product cannot crystallize onto the surfaces, because of the same scraping principle. Also the cover is scraped, so no product can accumulate there.Spinach crystallisation
The product is pumped through the Ftherm machine at constant pump capacity (your existing pump can be used for this). The Ftherm machine is equipped with a double shell, one wall of which is in direct contact with the product. A cooling medium is pumped through the double shell at a constant volume and temperature, while remaining fully segregated from the product. It is impossible for the cooling medium to come in o contact with the product.
The cold transfer occurs due to the cooling fluid being colder than the product, therefore cooling the product as a result of which it crystallizes. This cold exchange is very effective because the double wall is continuously and completely scraped. The scrapers prevent product from accumulating on the double wall, as a result of which the cold exchange is maximized throughout the entire production process.
