Due to the high viscosity, high sugar content, and poor air permeability of many extract materials. the materials are paste and sticky, and the materials cannot withstand high temperatures; these types of materials cannot be dried by a spray dryer. If it is dried in the ordinary vacuum shelf dryer, the drying time is usually more than 20 hours. Off course, microwave vacuum dryers have become popular in China and Asia in the past few years. The microwave vacuum dryer can complete the drying of such materials in a short time. In the process of use in pharmaceutical and food factories, it was found that microwaves have major damage to some material components. In recent years, vacuum microwave dryers have gradually withdrawn from the market in some fields.
In recent years, a high efficient vacuum dryer (also called a pulse vacuum dryer, a high-efficiency vacuum shelf dryer, intermittent supplemental air vacuum dryer) has been developed on the basis of pulsating sterilization equipment. The low-temperature high efficient vacuum dryer is a jacketed box-type device, which operates under low temperature and vacuum conditions, and the drying time is shortened from more than 20 hours in the traditional vacuum tray dryer to about 2-3 hours. This high-efficiency vacuum tray dryer has achieved a great breakthrough in drying speed, and after the materials are manually loaded, automatic control is set.
