Vacuum glass food containers are a common preservation tool in modern kitchens. They slow down food oxidation and bacterial growth by extracting the air inside the container, thereby extending the shelf life of food. However, sometimes we may encounter situations where the vacuum cannot be successfully extracted, which will undoubtedly affect its use effect. This article will explore in depth the reasons why vacuum glass food containers cannot be vacuumed and provide corresponding solutions.
1. Sealing ring problem
1.1 Aging or damage of the sealing ring
The sealing ring is a vital part of the vacuum glass food container. It is responsible for ensuring that the container does not leak when the vacuum is extracted. Over time, the sealing ring may age due to long-term use and lose its original elasticity and sealing. In addition, if it is frequently exposed to grease, acidic, or alkaline substances during use, it will also accelerate the aging of the sealing ring. Once the sealing ring is cracked or deformed, it cannot form an effective seal, resulting in the inability to extract the vacuum.
Solution: Check the status of the sealing ring regularly, and replace it with a new one if it is found to be aged or damaged. It is recommended that original accessories be purchased to ensure compatibility and quality.
1.2 Improper installation of the sealing ring
Even if there is no problem with the sealing ring itself, improper installation will cause leakage. For example, if the sealing ring is not fully embedded in the groove or the position is offset, the sealing effect will be affected.
Solution: When installing the sealing ring, make sure it is correctly placed and fully embedded in the groove. You can refer to the installation steps in the product manual, or watch the official installation video tutorial.
2. Vacuum pump failure
2.1 Vacuum pump damage
The vacuum pump is the core component to achieve the vacuum state. If the vacuum pump itself fails, it will naturally fail to complete the vacuum task. Common faults include motor damage, valve failure, etc.
Solution: First check whether the power cord is connected properly, and then try to use other electrical appliances to test whether the socket has electricity. If the power supply is confirmed to be correct but the vacuum pump still does not work, it may be that the internal components are damaged. You need to contact the manufacturer for repair or replace a new vacuum pump.
2.2 The vacuum pump does not match the container interface
Vacuum glass food containers of different brands and models may have different interface designs. If the vacuum pump does not match the container interface, it will also cause the vacuum to fail to be pumped normally.
Solution: Before purchasing, you should carefully check the interface specifications of the vacuum pump and the container to ensure that the two are compatible. If you have already purchased an incompatible product, you can consider purchasing an adapter to solve this problem.
3. Improper operation
3.1 Failure to operate according to the instructions
Many people do not read the instructions carefully when using vacuum glass food containers, resulting in operational errors. For example, some containers need to be manually pressed several times before the automatic vacuum function can be activated; some containers cannot open the lid during the vacuum process, otherwise, the vacuum state will be destroyed.
Solution: Be sure to read the product manual carefully before use and follow the correct steps. If you are not sure whether a step is correct, you can consult customer service or check the online tutorial.
3.2 Too much food
When the container is full of food, it is difficult to completely extract the air, especially when there is a lot of solid food. In this case, even if the vacuum pump works normally, it is difficult to achieve the ideal vacuum degree.
Solution: Avoid putting too much food in at one time, and try to leave a certain amount of space so that the air can be discharged smoothly. For solid food, you can cut it into small pieces before putting it in the container.
4. Environmental factors
4.1 Temperature changes
Temperature changes affect the density and fluidity of the air, which in turn affects the vacuum effect. Especially in a cold environment, the air becomes denser, which increases the difficulty of vacuuming.
Solution: Try to use vacuum glass food containers at room temperature and avoid operating under extreme temperature conditions. If it must be used in a low-temperature environment, the container can be preheated to room temperature before vacuuming.
4.2 High humidity
In a high-humidity environment, the water vapor content in the air increases, which not only affects the vacuum speed but also may cause condensation inside the container, further affecting the vacuum degree.
Solution: Use vacuum glass food containers in a dry environment, or use a paper towel to absorb the moisture inside the container before vacuuming. In addition, you can also consider using a dehumidifier to reduce indoor humidity.
5. Problems with the container itself
5.1 The container has cracks or defects
Although high-quality vacuum glass food containers usually do not have such problems, they may still have tiny cracks or defects after being hit during transportation or after long-term use, resulting in air leakage.
Solution: Carefully check whether the container has obvious damage. If found, replace it with a new container in time. Also, pay attention to handling with care during normal use to avoid damage caused by collision.
5.2 Unreasonable container design
Some low-priced or low-quality vacuum glass food containers may have design defects, such as poor sealing and unreasonable position of the vacuum port, which will affect the vacuum effect.
Solution: Choose products from well-known brands with good reputations, and ensure that the design of the container is reasonable and the quality is reliable. You can make a better choice by checking user reviews and professional reviews.
As an efficient preservation tool, vacuum glass food containers have brought great convenience to our daily lives. However, it is inevitable to encounter some problems during use, especially when the vacuum cannot be successfully extracted. From the above analysis, it can be seen that there are many reasons for this problem, including sealing ring problems, vacuum pump failure, improper operation, environmental factors, and problems with the container itself. In response to these reasons, we have proposed corresponding solutions, hoping to help everyone better use and maintain vacuum glass food containers and give full play to their preservation functions. In short, only by correctly understanding and mastering the methods of use can this modern kitchen product really play its due role.
