SPRAY FREEZING DRIER FOR UNIFORM DRYING PERFORMANCE

摘要

A spray freezing drier for uniformly drying samples includes a chamber, a tray, a freezing drying target object injection nozzle, a heating unit, and a vacuum pump. The chamber forms an accepting space. The tray is accepted in the accepting space of the chamber and includes a bottom part and sidewall part to form an accepting part, wherein the bottom part has a uniform pattern. The freezing drying target object injection nozzle accumulates freezing drying target objects on the tray by injecting the freezing drying target objects to the accepting part of the tray. The heating unit heats the tray accumulated with the freezing drying target objects. The vacuum pump maintains the inside of the chamber in vacuum.
