Abstract:
A heating and drying means for a spray freeze drying apparatus, comprising an outer cylindrical container for forming a closed space, a rotary dryer, and a temperature controlling circulating system. The rotary dryer that is partially provided inside the outer cylindrical container is used for accommodating and dynamically heating a material; the temperature controlling circulating system is connected to the rotary dryer and is used for controlling the heating temperature of the rotary dryer. The outer cylindrical container comprises an outer cylinder (1), which is provided with a material feeding pipe (2), a pumping port (3), and a material discharging port (4). The rotary dryer comprises a rotating cylinder (11), a motor (13), and a rotating shaft (12). A heating circulating system comprises a rotary joint (21), a heat exchanger (22), an electrical heater (23), and a fluid pump (24) that form a closed loop. The heating and drying method for a spray freeze drying apparatus comprises: adding a material to the rotating cylinder (11) by means of the material feeding pipe (2), wherein the rotating cylinder (11) continuously rotates during the drying process, such that the granular material keeps tumbling, so as to be heated by means of full and even contact with the cylinder wall.
