HYBRID TYPE FREEZER DRYER FOR EXTRACTING VALUABLE MATERIAL OF THE DEEP SEAWATER

摘要

The present invention relates to a complex vacuum freeze dryer applying spray nozzles to a conventional vacuum freeze dryer to dry extract a useful material of deep sea water in powder form.;The present invention is provided with a drying device equipped with a shelf having a plurality of trays on the inside and a hydraulic cylinder operated by a hydraulic pump on the upper side, an expansion valve installed at the inlet of the evaporator provided on the inner side and expanding the refrigerant; A steam collecting device having a valve, a refrigerating device comprising a refrigerant compressor, a condensation heat exchanger, and an intermediate heat exchanger; A brine heat exchanger connected to a shelf provided inside the drying apparatus and having a brine pump; A boiler connected to the steam collecting device and a drying device to generate steam; It is configured to include an air compressor for controlling the opening and closing of each valve.;In the present invention, the preliminary dynamics and drying in the form of a powder is made at the same time, the drying efficiency is also increased, a very good dry matter with low inertia followability, high spraying properties, small aerodynamic particle diameter is produced, according to the required drying method Existing vacuum freezing method can also be used, there is an effect that can use the vacuum freeze drying method using a spray nozzle.;Combined vacuum freeze drying, steam collecting device, vacuum device, spray nozzle
