Fruit Flower Herb Seafood Meat Freeze Dryer
Use of freeze dryer
1. Before starting each time, first check whether the pump oil in the vacuum pump is sufficient.
2. Unscrew the drain valve to let the remaining water flow out. Tighten the valve after draining.
3. Check whether the contact part of the freeze-drying chamber and the cold trap is intact, clean and readjust if necessary.
4. Close all valves (valves directly connected to the freeze-dried bottle, the white knob is up to close).
5. Turn on the power switch of the cold trap and turn on the power switch of the vacuum pump.
6. After 15 minutes, open the valve that connects the cold trap to the vacuum pump.
7. After 1 minute, the pre-frozen sample (already in the freeze-drying bottle) can be hung on the holder, and the corresponding valve can be opened to start the freeze-drying process.
8. After the freeze-drying is complete, close the corresponding valve (white knob upwards), and remove the freeze-drying bottle.
9. After all the freeze-dried bottles are removed, turn off the power of the vacuum pump and the cold trap in turn.
10. After the frost in the cold trap has melted, open the drain valve to drain, and then close it.

Characteristics and system introduction of KGJ-20
KGJ-20 can simulate the freeze-drying process in the whole process, can pre-freeze in situ, and can expand the functions of vacuum adjustment, automatic vacuum backfill, automatic drainage, etc.
Main feature:
The transparent door of the drying chamber adopts aerospace acrylic, high strength and no leakage.
The partition pre-freezing function.
Famous brand compressor, high efficiency and stability, low noise.
Famous brand vacuum pump, with high pumping speed and low noise.
It can be filled with nitrogen or inert gas for storage after drying.
Freeze-drying automatic control system: programmable programming, programmable control from freeze-drying to defrosting.
Layer heating control system: independent temperature control for each layer, thermal cycle monitoring and protection, special heating materials, fuzzy PID control algorithm.
Cold trap defrosting system: non-electric heating defrosting method, high safety performance; fast defrosting speed, which solves the inconvenience caused by traditional immersion defrosting (optional).
