Vacuum cooling fruits and vegetables machine 
 I. Overview: 
 Vacuum cooling is the world advanced pre-cooling method, and its basic principle is to use a vacuum system to reduce the environmental pressure to be cool things, cool things to be reduced and evaporation in the boiling point of water, which absorbs heat and be cool be cool thing in itself . 
 Vacuum cooling can be removed quickly and evenly to bring the harvest field heat, reduce the respiration of fruits and vegetables to significantly extend the shelf life and improve the preservation quality. Vacuum cooling is a cooling mode volume, the overall cooling rate, cooling even by way of a small packaging and stacking. Especially for vegetables, fruits, flowers, mushrooms and other cold chain preservation of pre-cooling.

 Third, the product features: 
 1, configured with dual-gas town of imported vacuum pumps, vacuum energy can be automatically adjusted, but also with a preparation; 
 2, configure the patented design of large heat capacity of impact energy-efficient water heater stainless steel catch. Overcome the copper coil pipe joints and more difficult to weld with the shell, easy to leakage problem; solve a lot of water vapor, "the flash" on cooling, vacuum system, the impact of water temperature fluctuations in small fishing and catch the water effect is good, equipment failure rate low, long life; 
 3, equipped with a vacuum thin film capacitance sensors and temperature sensors probe metal shielding, precision and accuracy measurement device; 
 4, the allocation of import vacuum valve, actuator is sensitive and reliable; 
 5, specific regulator control system, cooling rate is adjustable and has a function of chilling injury prevention; 
 6, precision CNC machining technology to ensure the equipment vacuum leak rate of less than 1 × 10-2mbar/L/sec; 
 7, with automatic and manual dual operating system; 
 8, configure the advanced PLC, touch screen control system, clear display and easy to operate, the professional design of hierarchical management and password protection, safe and reliable;
