Freeze Dry Machine is a new type of equipment integrating refrigeration system, vacuum system, heat transfer oil heating system and dehumidification system. It can use the material space in the box to dry. It is suitable for drying high-grade raw materials, traditional Chinese medicine, biology, wild vegetables, dehydrated vegetables, foods, fruits, chemicals, pharmaceutical intermediates and other materials.
In the past ten years, freeze-drying industry has made great progress and its application field has been gradually expanded. In the field of life science research, freeze-drying technology can be used in the research of antibodies, proteins, tissues and microorganisms, so it has been widely used in the field of biopharmaceuticals. Freeze drying is widely used in the pharmaceutical industry to prepare vaccines and antibiotics.
In the freeze-drying process, if there is a fault, it is easy to affect the working process. However, users will inevitably encounter some minor faults in the use process. To understand the cause of the fault and the corresponding solutions, in order to timely judge and eliminate the fault.
Frequently Asked Questions 1: Indoor Temperature Above 30℃
Freeze dryers need to be operated in a suitable environment. When the indoor temperature is higher than 30℃, the condenser may not be able to play a condensing role, making the system invalid. The maintenance method at this time is that if the indoor temperature is around 28℃, the user can open the back door of the condenser or the door of the room, thus optimizing the ventilation and cooling conditions.
Frequently Asked Questions 2: Excessive Humidity in Environment
When the humidity in the environment is high, it is easy to cause electrical failure or short circuit. In view of this situation, the maintenance method is to use ventilation equipment or open windows for ventilation, thus reducing humidity.
Frequently Asked Questions 3: Unstable Supply Voltage
It is understood that the normal operating power supply voltage of the freeze dryer is 215-225 volts. After deviating from the allowable voltage range, the compressor cannot operate effectively or even at all.
In view of the unstable power supply voltage, the solution is to replace the qualified power supply when the power supply voltage is unqualified. When the power supply voltage is unstable, AVR(220V) can be used or a voltage stabilizer can be added to the original working power supply.
Frequently Asked Questions 4: Excessive Dust on Vegetable Drying Equipment or in Environment
According to the investigation, if there is too much dust on the condenser and compressor, it is easy to make the condenser unable to achieve the condensation effect, which directly affects the use effect of the compressor.
Therefore, regular dust removal is essential. The industry suggests that if there is too much dust in the environment, users can regularly remove the dust covering the compressor and condenser every month. In order to prevent damage to Vegetable Drying Equipment, soft brushes can be used to remove dust from compressors, condensers and pipelines.
