9. What Are The Differences Between An Automatic Can Sealer And Capping Machine?

Both automatic can sealer machine and capping machines are used to apply the top covering to their packaging materials. But the operation and application of both the machine has greater difference. The differences among both of the machines are

• Working Principle

The operation of an automatic can sealer machine is designed in a way that the cans are sealed in a continuously running process. One after another cans are sealed with high precision and accuracy in automatic manner. Once the can is entered in the sealing system, a lid if fed on its top and the principle of sealing takes place. An automatic can sealer provides airtight sealing and prevents contamination.

On the other hand, a capping machine depends mostly on the efficiency of its operator. The machines are available in both manual and automatic operations but are mostly designed to produce batch processes. The operator is responsible to place the cap on the top and then it is tightens with the help of screw block. After capping process the worker takes out the product of the system.

• Characteristics

It can be count as a demerit of an automatic can sealer machine that it is designed to perform sealing on specific type of cans only. Products like drum, bottle or jar cannot be sealed using an automatic can sealer machine.

Unlike an automatic can sealer machine, a capping machine is compatible with any type of can, jar or bottle and also does not depends on the size and shape of product. Capping can be performed on these packaging materials and that is an important characteristic of the machine.

• Application

An automatic can sealer machines are used for applying lid on the top of cans and then heated to perform airtight sealing. These types of machines are applied food, pharmaceutical and chemical industry.

The design of capping machine is to tight the screws of caps on the top of bottle can or jar and gives a simple opening to it. Any type of product that is manufactured using cap on its top can be applied under a capping machine.

10. What Are The Auxiliary Components That Are Associated With An Automatic Can Sealer Machine?

There are always few auxiliary components that take part to complete the sealing process of an automatic can sealer machine. These parts hold a secondary role and can be adjusted according to their usage. Some of the auxiliary components that are associated with an induction sealing machine are

Material manufacturing and expiry dates are using these barcode writers. These writers are also used to give unique identification to each one of the can produced as a result of batch process.

• Sensors

To detect the presence of can under the filling nozzle and in the sealing system is sensed by highly active sensors. They also detect the flow of cans on the conveyor and signal the programmable system regarding it. Sensors help to avoid wastage of material also.

11. Why Nitrogen Need To Be Filled With Automatic Can Sealer Machine?

Nitrogen need to be filled with automatic can sealer machine due to various reasons. Some of them are

• Product Protection

The food industry has always been focused on providing consumers with fresh and high-quality products. However, food items are susceptible to spoilage due to bacteria and fungus that grows in the presence of oxygen.

In order to extend the shelf life of food items and preserve their freshness, nitrogen gas is used in the packaging process. Nitrogen gas creates an environment that is inhospitable to bacteria and fungi, thereby preventing spoilage.

• Minimizing Risk Of Contamination

These machines offer a number of benefits, including consistent and efficient operation, which is essential for large-scale packaging operations. The use of automatic can sealer machines also minimizes the risk of contamination, as the machines are designed to prevent the introduction of foreign matter into the packaged food.

• Food Preservation

In addition to preserving the freshness of food items, nitrogen gas also provides protection against oxidation, which can result in the loss of flavor, aroma, and nutritional value. This is especially important for items such as coffee and chips, which are highly susceptible to oxidation.

• Maintaining Oxygen Level

When the automatic can sealer machine is used to fill the packages with nitrogen, it first vacuums the air out of the package. The nitrogen gas is then introduced into the package, replacing the air. This creates an environment with a low oxygen level, which is hostile to bacteria and fungi.

• Product Integrity

The use of nitrogen in the packaging process also helps to maintain the integrity of the food product. For example, chips that are packaged with nitrogen are less likely to become crushed or broken, as the nitrogen gas provides a cushion to protect the chips from damage.
