Features of freeze-drying 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, supplies hot air to the drying chamber, and heats it up. 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%.

Features of the petal drying equipment: The petal drying equipment needs to be installed on a smooth concrete floor. The area is spacious, bright and ventilated. Does it require a 100 square meter site with a length of 8 meters, a width of 4 meters and a 2.5 meter size? High processing plant. Workshop, installed 36 1.7 medium three rows of about 10 cm diameter, heat pump, heat pump double-sided line 9 holes, 6 holes, in each row, even spacing. All safety depends on one side of the wall of the processing room, the heat pump pores are vented, and a row of double-sided vent heat pumps in the middle of the wall. The processing plant is divided into two drying equipment rooms, and the drying equipment is underground in each room on the ground. Exhaust pipes, exhaust ports, and moisture in the drying equipment room have caused electrical discharge and have left the factory next door. The two safety seals of each drying equipment room are intact, the doors are opened and closed, and the car is in and out of the air. An indoor thermometer is installed on the outside iron door, and the temperature of the drying chamber can be observed outdoors to adjust the temperature as needed. Each drying pump can be arranged along the drying chamber with six drying carts; each drying vehicle is 1.4 meters long, one meter wide and 2.2 meters high. It is divided into 12 layers with two rows and can accommodate 24 bags of buds. Adjacent to the processing chamber, equipped with automatic temperature adjustment device, and a plate spiral air dryer and a large 300,000 kW cooling fan wall. The plate type spiral airflow dryer generates a hot air ventilation pipe with a temperature of up to 200 °C formed by a cold mixed phase of the high temperature airflow and the air cooler, and then sends it to the processing plant, and then discharges the temperature of the drying room by heat pump and buds to perform heating and drying. The normal working time of the treatment plant, under normal circumstances, the indoor temperature is 50-95 ° C, the bud, about 8 hours from the drying process of the feed material.
