Jellification is defined as the process of turning a substance into a gelatinous form. With this process, liquid substances are converted into solids with the help of a gelling agent. Common gelling agents come from natural sources and include agar-agar, gelatin, Carageenan, gellan gum, pectin and methylcellulose. More often than not, these gelling agents are presented in a dry, solid form which needs to be hydrated.Jellification

 

All of these are hydrocolloids and react when dispersed in liquids. Gels resulting from this process may range from tough and hard to weak and soft. Gels are characterized by having a viscous property when heated and becoming solid or jelly like once cooled. Melting and cooling points for gelling agents may differ according to type.

 

Jellification Applications

The food industry use the jellification process the most, but they are not the only one. Also in feed, pharma and non-food industries it is used.

 

Puddings

Desserts

Dog and cat food in Jelly

Pharmaceutical gels

Hair gel

Why using a Ftherm Scraped Surface Heat Exchanger?

The Ftherm is ideal when, as part of a continuous process, you wish to jellify / stiffen your product.

 

If, for example, we assume that gelatine is the basis of the jelling agent, then this gelatine must be mixed in a fluid. For this reason, it is important that the mixture begins to jellify / stiffen by means of controlled mixing and cooling. The mixture will then be further processed by, for example, using whipped egg whites to make it fluffy.Scraped Surface Heat Exchanger Ftherm

 

The product is pumped through the Ftherm at constant pump capacity (your existing pump can be used for this). The Ftherm 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 into 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 jellifies / stiffens. 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.
