Yuzu sauce and blueberry sauce vacuum capping machine

In the field of jam production, vacuum capping machine is a key equipment to ensure product quality and extend shelf life. Choosing a suitable vacuum capping machine is particularly important for high-value jam products such as grapefruit sauce and blueberry sauce. This article will provide you with a detailed introduction to the key points for selecting and using a vacuum capping machine.

1、 Working principle of vacuum capping machine
The vacuum capping machine uses a vacuum system to extract air from the bottle before sealing, creating a negative pressure environment. The capping device then tightly tightens the bottle cap to ensure that the vacuum inside the bottle meets the standard. This process can prevent the jam from oxidizing and deteriorating, and extend the shelf life of the product.

2、 Purchase precautions
1. Material requirements: Due to the acidity of grapefruit sauce and blueberry sauce, the equipment contact part is made of 304 food grade stainless steel material to avoid corrosion and contamination.

2. Vacuum control: Jam usually requires a vacuum degree of 0.08-0.095MPa. When making a purchase, it is necessary to confirm the adjustable range of vacuum degree of the equipment to meet different packaging requirements.

3. Applicable bottle types: Suitable for glass bottle specifications, round bottles, hexagonal bottles, square bottles, etc. Including parameters such as bottle mouth diameter and bottle body height.

3、 Key points for use and maintenance
1. Operation specifications: Before starting up, check the status of each component to ensure that the oil level of the vacuum pump is normal. Keep the bottle body vertical during operation to avoid tilting and poor sealing.

2. Daily cleaning: Clean up residual jam in a timely manner after each use, especially the capping head and vacuum chamber area. Regularly disinfect with food grade disinfectants.

3. Regular maintenance: Replace the vacuum pump oil according to the instructions and check the wear of the sealing ring. It is recommended to conduct professional maintenance once every quarter.

4. Common problem handling: If there is insufficient vacuum degree, first check whether the pipeline leaks; When the screw cap is not tight, adjust the torque parameters or replace worn parts.

4、 Recommended mainstream models in the market
1. Economic type: semi-automatic type, with a production capacity of 1200 bottles/hour, basically meeting the needs of small-scale production.

2. Double head type: Fully automatic double head vacuum capping machine, with better stability and adjustment function, suitable for medium-sized enterprises.

3. Fully automatic: Fully automatic four head, six head, integrated automatic cover, detection and other functions, suitable for large-scale production.

5、 Evaluation of Usage Effectiveness
The vacuum capping machine should meet the following standards:
-Sealing qualification rate ≥ 99%
-Stability error of vacuum degree ≤ 0.005MPa
-The ideal range for bottle cap opening torque is 0.6-2.2N · m

Conclusion:
Choosing a suitable vacuum capping machine can not only improve the product quality of grapefruit sauce and blueberry sauce, but also significantly extend the shelf life. It is recommended to conduct on-site inspections of equipment operation before purchasing and request suppliers to provide trial services. Proper use and maintenance will enable the equipment to perform well and safeguard your jam products.
