Fruit Vegetable Food Vacuum Freeze Dryer Touch Screen PLC Freeze Vacuum Dryer

    GZVF series freeze dryers use double color touch screen and PLC as control center ,control system stable and reliable. it can store 33groups of freeze drying program , and each program can be set up 36 segments. It can display freeze drying curve and automatically records data.Freeze drying data can be output by USB flask disk.

    GZVF series freeze dryers use Bitzer refrigeration unit,condenser temperature can reach < -75℃ , performance stable .This model is suitable for production.

Features of Toption GZVF-12 Vacuum freeze dryer:
1. Vertical cylindrical condenser,compact structure,with good water capture capacity, no dead corner, easy for defrosting and cleaning.
2. Pre-Freezing and drying process are both finished on shelf.
3. Silicon oil as circulation medium, with high accuracy of temperature control.Shelf temperature uniformity ≤ 1℃ , with uniform drying effect.
4. Shelf temperature adjustable , controlled, suitable for pilot and production.
5. Touch screen operation,PLC control, display drying curve.
6. Square tray easy to operate and clean.
7. With charging valve, to fill dry inert gas.
8. Optional eutectic point test functions.
9. Optional PC software to realize the remote control.
10. Ozone disinfection function is optional.

Technical advantages of GZVF series freeze dryers:
1. Vertical cylindrical condenser,compact structure,with good water capture capacity, no dead corner, easy for defrosting and cleaning.
2. Refrigeration system protection control device: adopt international famous brand products, accurate, stable, safe and reliable.
3. High pressure protection system: when the system exhaust pressure more than allowed, refrigeration unit running will be automatically cut off , to prevent accidents.
4. Middle pressure regulation system: in the double-stage refrigeration system, proper middle pressure are very important for operation performance and life of the refrigeration system. When middle pressure below the set value, the system will automatically start to adjust. Create conditions for the realization of the lyophilizer unmanned operation.
5. Oil pressure protection system: when the long time operation of the refrigerator, monitor the hydraulic pressure of the refrigerator, prevent refrigerator damage because of oil lack.
6. The motor temperature protection system: when the refrigerator motor temperature higher than the set value, in order to protect the refrigerator, the system will automatically stop the operation of the refrigerator.
7. Oil return at low temperature regulating system: when refrigerator works under very low evaporation temperature for long time , how to make the refrigeration oil well back to the crankcase is very important (lack of refrigeration oil in the system often causes refrigerator "burned"). When the crankcase lack of refrigeration oil, the system automatically start to establish proper oil level in the crankcase. Create conditions for the realization of the lyophilizer unmanned operation.
8. Exhaust temperature control system: when refrigerator exhaust temperature is too high, the system automatically start cooling system, to prevent the high pressure part of overtemperature operation. Create conditions for the realization of the lyophilizer unmanned operation.
9. Wet stroke prevention control system: when the high load operation of the refrigerator, the system can automatically go in the process of adjustment, prevent the wet stroke even "liquid impact phenomenon". Create conditions for the realization of the lyophilizer unmanned operation.
10. Automatic liquid collection device: when the refrigerator is in standby mode, the device will automatically run , to collect stranded refrigerant in the system to storage tank, in order to start the freeze dryer again.
11. The machine start protection: when equipment has all security conditions , the machine will be able to start running.
12. whole machine structure longitudinal, front and back split type (convenient for transport and placing ).
13. Ozone disinfection function is optional.

The features of goods after vacuum freeze drying:
1.After vacuum freeze drying  goods are easier for long-term preservation. 
2.After freezing-drying processing, goods can be restored to the original state.
3. Maintain goods's chemical and biological characteristics after being watered.
