There is a large cavity where in fact the freezing of the product is performed, in addition to a machine pump that is used to get rid of the water/moisture form the product เครื่องฟรีซดราย. After this is done, then there is the application of heat that serves to accelerate the sublimation process. There's then condensation, wherein the vaporized solvent is taken off the chamber of the vacuum with the conversion of the solvent to a solid state. When this is completed, the separation of the water/moisture from the merchandise has been completed. Since the 1960s there were a lot more than four hundred finds of freeze-dried foods that have produced on a professional level. Some products; such as for example coffee are extremely suitable for this process, but other products such as for example water melons and lettuce due to their high water content are not very good items for the freeze-drying process. Mountain House is a producer of a number of freeze-dried products. They will be in operation for more than fourth years. They've products such as for example eggs, beef stew, and rice pilaf.
