Shanghai Haozhuang Instrument Co., Ltd. has developed the LNB brand freeze dryer, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable.
Principle: The humid and high-temperature compressed air flows into the pre-cooler (for high-temperature type) to dissipate heat, and then flows into the heat exchanger to exchange heat with the cold air discharged from the evaporator, so that the temperature of the compressed air entering the evaporator is reduced. The compressed air after heat exchange flows into the evaporator and exchanges heat with the refrigerant through the heat exchange function of the evaporator. The heat in the compressed air is taken away by the refrigerant, the compressed air is quickly cooled, and the moisture in the humid air reaches the saturation temperature and quickly condenses. The condensed moisture forms water droplets after condensing, and rotates at a high speed through a unique air-water separator. The moisture is separated from the air due to the centrifugal force, and the separated water is discharged from the automatic drain valve. The air pressure dew point after cooling down can be as low as 2 ℃. The cooled cold air flows through the air heat exchange and exchanges heat with the high temperature and humid hot air at the inlet. The cold air after heat exchange raises the temperature due to the absorption of the heat of the inlet air, and the compressed air also passes through the secondary condenser of the refrigeration system (Unique design) The heat exchange with the high-temperature refrigerant reheats the temperature of the outlet to ensure that the outlet air line does not condense. At the same time, the cold source of the outlet air is fully utilized to ensure the condensation effect of the machine refrigeration system and the quality of the machine outlet air.
The main controller â‘ , ON / OFF button switch is installed on the instrument panel of the machine, used to control the operation and stop of the machine. â‘¡ The high and low pressure protection switch of the refrigeration system is installed in the machine to control the pressure of the high and low pressure ends of the refrigeration system to avoid damage to the equipment caused by the pressure of the machine exceeding the use range. â‘¢ The defrosting solenoid valve is installed in the machine to control the condensing pressure of the machine to avoid the low condensing pressure of the machine and causing ice blockage of the evaporator.
Description of the main instrument and main control switch of the machine: the main instrument of the machine is composed of the compressor air pressure gauge, refrigerant high pressure gauge, and refrigerant low pressure gauge; the main controller is composed of the ON / OFF button switch, the high and low protection switch of the refrigeration system, and the antifreeze switch . â‘ The air pressure gauge is installed on the instrument panel to display the pressure of the compressed air of the machine. The table is composed of several scales. Mpa and Kg / CM2 at the bottom of the table represent the unit value of pressure. When reading the pressure value, just observe the scale value corresponding to the pointer on the meter plus its relative unit value. â‘¡ The refrigerant low meter is installed on the instrument panel and is used to display the pressure or temperature of the low pressure end of the refrigeration system. The meter is composed of several scales and the reading method is the same as the high pressure meter.
