Toaster (Desolventizer)
Equipment Description
Desolventizer, or toaster, is used for wet-heat treatment of solvent-containing meal (defatted raw material residue) of oilseeds after the process of oil extraction with a solvent. Thus, solvent residues are removed.
Operating principle
Toaster is a vertical column consisting of several trays that are heated by steam. The number of trays and their diameter depends on the capacity of the extraction line on which the toaster is installed.
In the upper part of the toaster there is a cap with nozzles above the upper tray. It is used to supply meal, as well as to remove solvent vapors. Under the bottoms of the trays there are collectors with nozzles that supply direct steam through the bottom grate, which improves the process of distillation of the solvent and conditioning of the meal. Each trays is also equipped with paddle mixers, which are used to move and mix raw materials. They are rotated with a common shaft.
The toaster is also equipped with control valves – they maintain the required level of meal in the trays during the continuous operation of the toaster. Valves can change the level of meal in each individual tray, without stopping the operation of all equipment.
At the customer’s request, the product temperature at the outlet can be adjusted automatically or manually.
