SSFD-2500 freeze dryer (freeze-dried area: 2500m2) (This model is a split model of rail car and quick freezing warehouse) The largest standard size freeze dry machine is SSFD-2500. The processing capacity of fresh ingredients is 2.5 tons per batch. If a daily processing of 2.5 tons is required, the freeze dry machine has a remote terminal system that can be viewed and operated simultaneously on both PC and mobile devices. You can choose one SSFD-2500 or two SSFD-1200 freeze dry machines. If the daily processing capacity is 5 tons, two sets of SSFD-2500 can be selected. The freeze-drying process of SSFD-2500 is as follows: Freshly prepared materials must first be frozen in a freezer to -30 ℃ or -40 ℃. The refrigeration system provided by SHENSHENG will provide sufficient cooling capacity for the quick freezer. It will take about 3 hours as this is rapid freezing. The advantage of quick freezing is the formation of small ice cubes inside the material, ensuring the quality of freeze-dried products. The second step in the freeze-drying process is to stop the refrigeration of the quick freezer and start the refrigeration of the steam condenser. A steam condenser is also known as a cold trap. Used to collect water vapor from the freeze-drying mechanical chamber. It will cool to -40 ℃ within a few minutes. The third step of the freeze-drying process is to activate the vacuum system to expel air from the freeze-drying mechanical chamber, thereby creating a low-pressure condition in the chamber. This is a necessary condition for sublimation. The fourth step of freeze-drying is to transfer heat into the freeze-drying mechanical chamber through a heater and liquid circulation pump. Heating resources can be electricity, steam, solar energy, or waste heat recovered from other systems. Within approximately 20 hours, the material will be dried. The freeze-drying time varies depending on the material or freeze-drying formula. freeze dryer is an advanced material drying equipment. This device has EU CE certification
