There are many advantages to the application of vacuum freeze-drying technology, and its application in various related fields is becoming increasingly widespread. The application of freeze-drying technology cannot be separated from freeze-drying machines. In order for the Yetuo freeze-drying machine to smoothly carry out the freeze-drying process, in addition to issues such as equipment performance, freeze-drying process, and parameter settings, application personnel should also pay attention to the operating environment of the Yetuo freeze-drying machine, which is also one of the basic conditions for a smooth freeze-drying process. Let's analyze the common problems that arise in the operating environment of freeze-drying machines and how to solve them.

Problem 1: Unstable power supply voltage for freeze-drying machine

The working power supply voltage of Yetuo freeze-drying machine is 225 volts. If it deviates from the allowable voltage range, the compressor of the freeze-drying machine cannot work normally or even operate, which affects the operation of the equipment.

resolvent:

In the case of unstable voltage, when the power supply voltage is not qualified, replace it with a qualified power supply; When the power supply voltage is unstable, AVR (220V) can be used or a voltage regulator can be added to the original working power supply.

Problem 2: High indoor temperature

The Yetuo freeze dryer needs to operate in a suitable environment. When the indoor temperature is above 30 ℃, the condenser may not be able to condense, causing system failure.

Solution: If the indoor temperature is around 28 ℃, users can open the back door of the condenser or open the room door to optimize ventilation and cooling conditions.

Question 3: Indoor temperature below 0 ℃

The indoor temperature is too low and not suitable for the operation of the freeze dryer. If the indoor temperature is below 9 ℃, the compressor oil of the Yetuo freeze dryer will become viscous, which can easily affect the normal operation of the compressor. Additionally, when the temperature is too low, the electronic components of the freeze dryer may be affected.

Solution: When the ambient temperature is below 0 ℃, other heating devices can be used to raise the ambient temperature and keep it above 5 ℃ and below 30 ℃.

Problem 4: Excessive dust in the environment

If there is too much dust covering the condenser and compressor of the freeze dryer, it is easy for the condenser to fail to achieve the condensing effect, directly affecting the performance of the compressor.

Solution: If there is too much dust in the environment, regularly clean the dust covering the compressor and condenser every month. To ensure that the equipment is not damaged, dust on the compressor, condenser, and pipelines can be removed using a soft bristled brush.

Problem 5: High environmental humidity

When the humidity in the environment is high, it is easy for electrical faults or short circuits to occur.

Solution: Use ventilation equipment or open windows for ventilation to reduce humidity.
