Gelatin evaporation

Quality of gelatin and evaporation process control

Acidification of bone and skin and lime treatment can produce gelatin, it is a selective hydrolysis of collagen protein derivatives.

Through acidification process gelatin, bone will stop in dilute acid solution or skin for a fixed time.Then use cold water washing solution, in order to make the pH drop to around 4.

In the process of lime treatment, bone or skins are put into the lime pit with lime.And then, washing raw materials, to remove residual lime and hydrolysis of organic impurities.

Next, the need to deal with gelatin in order to get the different quality of products.That is, the concentration of about 5% of the gelatin extract filter, ion exchanger in ion, and then concentrated in multi-effect vacuum evaporator.Solution will be sent to you by cellulose filter cake filtration and evaporation concentration.Then concentrated solution for sterilization, it cools and extrusion for gelatin.Finally in the tunnel dryer to dry gelatin product.

Visa K - PATENTS^®In situ online refractometer can be used in the quality of gelatin and important step in the subsequent operation efficiency play a key role.Read the application instructions, details about the use of the refractometer method and gelatin production process.
