  With the pursuit of health, people increasingly value the freshness of food and the nutrition of food. Cold logistics has developed rapidly and freeze-drying equipment is widely used.

  Features of Lyophilization equipment :
  First, energy saving (power saving equipment) has a remarkable effect. Compared with conventional steam drying, the energy saving rate is 40%-70%, among which the energy saving rate of single heat source drying equipment is about 40%, and the energy saving rate of double heat source drying equipment is about 70%. The main difference between drying and conventional steam drying is that the air circulation mode of the former is basically a closed cycle. After the humid air discharged from the drying chamber is dried by the drying evaporator, the dry hot air is sent back to the drying chamber, which is reduced compared with steam drying. The heat loss of the intake and exhaust gases is significantly reduced. The single heat source differs from the dual heat source dryer in that the latter has two evaporators. The drying evaporator takes heat from the humid air discharged from the drying chamber, and the heat pump hair dryer absorbs heat from the atmospheric environment and supplies hot air to the drying chamber to raise the temperature. According to the test, when the ambient temperature is above 14 °C, the compressor consumes 1 kWh. Electricity can get more than 3 times of heat. The drying chamber using a single heat source drying device is currently mainly heated by an electric heater. Therefore, the single heat source has higher energy consumption than the dual heat source drying device.

  Second, the dry quality is good, the color of the dried articles is good, and drying defects such as mold, deformation, cracking and surface hardening are generally not suitable. Therefore, the drying method is particularly suitable for drying difficult-to-dry materials and precious materials which are easily deformed and cracked. Most of the export materials that require high drying quality are currently dried.

  The third is to protect the ecological environment. Because this kind of drying technology does not need boiler equipment, there is no fire hazard, and there is no smoke pollution. Therefore, it is especially suitable for use in areas with high environmental quality requirements. The fourth is to invest in provinces, quick results, and low operating costs. When the dry volume is the same, the total investment in the entire plant is slightly lower than steam drying. Since there is no need to build a boiler room, the drying indoor equipment is simpler than steam drying. Therefore, as long as the funds and equipment are in place, it usually takes about 4 months to start production. At the same time, due to the high degree of automation of the equipment, the operation is simple, only one person per shift, and the drying energy consumption is low, so the running cost is small. The cost of dry items can be reduced by an average of about 20%.
