The evaporation is obtained under an adequate vacuum degree. With this plant it is possible to realise different process continuous and batch concentration. It is also possible to repeat the concentration step many times until a desired concentration degree is reached. The Thin Layer Evaporator Concentrator evaporator plant was designed in order carry out test of concentration of alimentary product such as fruit juice, milk, sugar solution, tomato sauce or other liquid, under vacuum and thin film productions. The process of concentration of above products is obtained by evaporation of the solvent (water normally) with the result to increase the degree of food conservation.
