6 Major Problems And Measures Of Vacuum Freeze Dryer Machine

Through this whole article you will learn some basic information about the vacuum freeze dryer machine.

This article mainly introduces 6 major problems and some related measures about vacuum freeze dryer machines.

I believe that by mastering these 6 common problems, you can solve these problems more efficiently if similar problems occur during the operation of the vacuum freeze dryer machine in the future.

The freeze drying process is a heat and mass transfer process involving refrigeration, vacuum, electronics, chemistry, biomedicine and other disciplines. The process has high technical content and complex freeze-drying process.

You should know that, the vacuum freeze dryer machine plays an important role in the pharmaceutical industry.

It not only reduces the possibility of materials’ oxidative deterioration, wiping out the germs in the materials, making sure the material’s original shape has a good reservation, but also can further reduce the risk of pollution.

At present, the vacuum freeze dryer machine is suitable for drying materials such as bulk drugs, Chinese medicine decoction pieces, biological and pharmaceutical intermediates.

In recent years, the pharmaceutical industry has continued to move forward.

The vacuum freeze dryer machine manufacturers constantly strengthen technology innovation and promote the equipment to make a greater breakthrough.

So, the vacuum freeze dryer machine can be better used in the pharmaceutical drying industry.

As you know, if the vacuum freeze dryer machine has some problems in the course of work, it will easily influence the process of work.

However, it is inevitable that you will inevitably encounter some minor faults in the process of using the equipment.

You need to know the causes of the faults and the corresponding solutions, so as to make timely judgments and eliminate the problems.

In terms of this situation, this article lists several common problems of the vacuum freeze dryer during operation, and analyzes the causes and solutions for your reference.

Unstable power supply voltage

It was understood that the normal working power supply voltage of the vacuum freeze dryer machine is 215-225 V.

When the vacuum freeze dryer machine deviates from the allowable voltage range, the compressor can not work effectively or even can not operate.

For the problem of unstable power supply voltage, the relative solution is that when the power supply voltage is unqualified, you need to replace the qualified power supply.

When the power supply voltage is unstable, you can use AVR (220V) or add a voltage regulator to the original working power supply.

Second, the indoor temperature is higher than 30℃

When you operate a vacuum freeze dryer machine, you need to run it in a proper environment. If the indoor temperature is higher than 30℃, the condenser may not be able to condense, causing a series of problems in the vacuum freeze dryer machines’ system.

When encountering this problem, if the indoor temperature is around 28 ℃, you need to open the rear door of the condenser or the room door to optimize the ventilation and cooling conditions.

Third, the indoor temperature is lower than 0℃

As you know, the indoor temperature of the vacuum freeze dryer machine is too high and too low is not suitable.

If the indoor temperature is lower than 9 ℃, the compressor oil will become viscous, which will easily affect the normal operation of the compressor.

In addition, if the temperature is too low, all electronic components may be affected and there will be some errors in operation.

In view of this situation, the maintenance method recommended by the technician is that when the ambient temperature is lower than 0 ℃, other heating equipment can be used to raise the ambient temperature and keep the temperature above 5 ℃ and below 30 ℃.

Fourth, too much dust on the vacuum freeze dryer machine or in the environment

It is understood that if too much dust covers the condenser and compressor, it is easy to make the condenser unable to achieve the condensing effect, which will directly affect the use effect of the compressor.

Therefore, you need to regularly remove the dust on the vacuum freeze dryer machine.

Professionals suggest that if there is too much dust in the environment, you can choose to regularly remove the dust on the compressor and condenser every month.

In order to ensure that the vacuum freeze dryer machine is not damaged, the dust on the compressor, condenser and pipeline shall be cleaned with a soft brush as far as possible.

Fifth, the humidity in the environment is too high

When the humidity in the environment is high, it is easy to cause electrical failure or short circuit.

In this case, the maintenance method is that you can use ventilation equipment or open windows for ventilation to reduce humidity.

Sixth, occurrence of high voltage alarm

The causes of high voltage alarm of the vacuum freeze dryer machine are as follows:

The water in the water condenser is insufficient or the water temperature is too high.

Some scale is formed inside the vacuum freeze dryer machine’s water condenser, which reduces the heat conversion efficiency.

When the vacuum freeze dryer machine’s compressor is working, the low-pressure pipeline breaks, making the air enter the refrigeration pipeline.

The valve of the refrigeration pipe is not fully opened, or the exhaust pipe is blocked, causing poor exhaust.

Too much use of the refrigerator leads to excessive exhaust pressure.

In this case, you need to reduce the water temperature or increase the flow; clean the water condenser.

If this operation cannot be carried out in the working state, you can open the stop valve above the water condenser to release some of the air from the water condenser.

Then you need to open the valve on the compressor pipe to the maximum and discharge part of the refrigerator.

Above all is the introduction of 6 major problems and measures of vacuum freeze dryer machine.

Although you will be confronted with many problems during the production process of the vacuum freeze dryer machine in the future.

When you master the solutions to these six problems and solve new problems on the basis of these six problems, it will become a very easy thing.
