It uses built-in alternately working water vapor traps, full-liquid circulating cooling systems, heating and water vapor capture systems designed for accelerated sublimation theory, and advanced technologies such as vacuum steam melting.

The quality of freeze-dried fruit is manufactured in the production process, not in the inspection. It not only has requirements for the fruit freeze-drying machine, but also has specific requirements for the hardware of the factory. The author combines his own work experience.

5 The factory building should be able to prevent animals and insects from entering, and its internal surface should be smooth and less cracked, and should not smash or adsorb particulate dust.

6 Plants must be graded according to the production process and quality requirements, general production areas (referring to the production workshops, rooms, etc. required for aseptic drop), control areas (referring to the production workshops and auxiliary rooms with certain requirements for the number of colonies), and should Take appropriate assurance measures.

7 Control area The inner wall, flat top and floor of the workshop should be hard, smooth and smooth, no gaps, no particulate matter falling off, easy to clean, easy to disinfect, room with external window, the window should be sealed, the door requirements are smooth, the shape is simple Closed tightly, the opening direction should be toward a room with a high degree of hygiene. The air entering the control zone shall be filtered by primary effect and medium efficiency. The indoor temperature and humidity shall be in accordance with the process requirements. Generally, the positive pressure of 1~2Pa shall be maintained, and the ultraviolet light shall be installed in a suitable place. light.

8 Operators should be able to enter the production control area through the buffer room after changing clothes. At least the clothing in the production control area must be unbuckled white coat.

9 Materials and tools entering the production control area should be cleaned through the buffer chamber before being disinfected.
