Vacuum Packaging Machine Precautions

At present, there are many companies in the country that produce vacuum packaging machines. The quality of these companies is uneven, which has brought difficulties to the procurement of food companies. Then, what matters should food companies pay attention to when choosing a vacuum packaging machine?

How to buy vacuum packaging machine

It requires a high-quality vacuum pump inside the machine. The vacuum pumps of well-known brands in Nantong and Shanghai in China are of better quality. The German BUSCH vacuum pump is also a quality pump.

The electrical components must be selected and manufactured by a standard low-voltage appliance company to ensure safety, reliability, and durability, because the electrical control part is the brain of the packaging machine. The composition of the complete machine control line must ensure the convenience of maintenance and the versatility and standardization of spare parts. It is strictly forbidden for vacuum packaging machine manufacturers to use the old series, old model, and old-style electrical switches and their components that have been explicitly eliminated by the national electromechanical management departments. Although these components can save a part of funds for machine manufacturers and enterprises, they will give Users have a lot of troubles, such as high failure rate of the machine, poor vacuum, and short service life.

The steel material from the material to the thickness must be able to meet the frequent use requirements and hygiene standards, especially the structure and material quality of the vacuum chamber body must meet the food-grade health standards and thickness and strength standards. In principle, for a high-quality packaging machine, when a manufacturer or distributor is selling, it is possible to promise a long-term "three guarantees" service to the parts of the vacuum chamber, instead of a six-year or one-year service commitment.

The appearance design of the entire machine should be reasonable and beautiful, and meet the specialization and standardization requirements of mechanical and electrical products, and have basic security. Various warning signs must be complete and marked at key locations. The nameplate must indicate the equipment number, date of manufacture, technical parameters, and implementation standards.

The standard currently being implemented by vacuum packaging machine manufacturers is the GB9177-88 standard. The distinction between machine models is mainly based on the length of the design sealing of the machine (ie, the length of the heating row). For example, a vacuum packaging machine with a heating row length of 400 mm is called a 400-type vacuum packaging machine; a machine with a heating row length of 500 mm is called a 500-type vacuum packaging machine; and so on, the vacuum packaging that appears on the market Machine models usually have 400, 500, 600, 680, 700, 800 type. In addition, there are many non-standard vacuum packaging machines that are custom-made according to customer requirements.

In addition to the length of the heating row, there are other more important technical parameters in the structure of the vacuum packaging machine. These parameters vary with different manufacturers and different brands of vacuum packaging machines. However, the current naming methods for vacuum packer models mask the differences between these technical parameters. For example, a vacuum packaging machine with a double row spacing of 350 mm and a sealing length of 400 mm is called a 400-type machine; and a vacuum packaging machine with a double-row spacing of 450 mm and a sealing length of 400 mm is also called a 400-type machine. . In addition, the single-chamber type machine and the double-chamber type machine also determine the machine type based on the sealing length.

When choosing a vacuum packaging machine, users should not simply choose which machine to use based on the model. Due to the different package sizes of the foods and packaging used by each user, the requirements for the technical level and work efficiency of the vacuum packaging machine are not the same. Users should choose the right vacuum packaging machine according to the characteristics of their products. The main basis for the user to buy a vacuum packaging machine is the sealing length, double-row spacing, the maximum available height of the vacuum chamber, and the overall production efficiency.

When the vacuum packaging machine is of the same model, the products produced by different manufacturers, apart from the above mentioned aspects, are not the same, but the key lies in the level of configuration of the main components and the quality of the products. In general, the key factor determining the manufacturing cost of a vacuum packaging machine is the cost of the internal configuration components, and the quality of the internal configuration components also plays a decisive role in the overall quality of the vacuum packaging machine. The selection of vacuum pumps and electrical components produced by high-quality, high-quality manufacturers is the key to ensure that the machine has good working performance and longevity. At the same time, the selection of a large pumping rate (high pumping rate) vacuum pump is also an important measure to improve the working efficiency of the machine. Of course, the use of high-quality components will also increase the cost of the equipment.

Whether you are ordering equipment at the factory or at the dealership, you must have a detailed understanding of the professional service capabilities and service attitude of the manufacturer or distributor. Try to select the manufacturers or businesses that have good after-sales service conditions and achieve real results. After-sales service agreement.

When the user purchases equipment, technicians with certain electromechanical knowledge can first go to the machine manufacturer to observe the required machines, and do a variety of understanding of the equipment, and must not only purchase machines from the outside.

Non-standard vacuum packaging machine order

Users who order special specification (non-standard) vacuum packaging machines need to provide the following information to the equipment manufacturer in order to let the equipment factory determine the structure of the machine and the quotation of the equipment:

1. What products (characteristics, shapes) are packaged and what the packaging is designed for.

2. The size of the used bag (length, width, height), the size of the bag after filling the material.

3. Packaging speed.

4. The requirements of the production environment for the material and structure of the equipment.
