Peanut Packaging Machine Granule Packaging Machine Related Knowledge

Among food packaging machines, peanut packaging machines play an extremely important role. They can effectively improve packaging efficiency, ensure product quality, and meet the diverse needs of the market. The emergence of peanut packaging machines is deeply loved by small entrepreneurs, so many buyers want to know the relevant knowledge of peanut packaging machines. Today, I will give you a comprehensive introduction to this packaging machine.

What is a peanut packaging machine?

Peanut packaging machines belong to granule packaging machines. They are mechanical equipment specially used for packaging peanuts and their products, such as peanuts, biscuits, nuts and other granular materials, and for automatic packaging. According to the different production scales and packaging requirements, it can be divided into many types:

(1) Small packaging machines: suitable for small-scale operations, such as packaging of a small amount of peanut products in family businesses, where the packaging volume is not large and the functional requirements are relatively simple.

(2) Medium-sized semi-automatic packaging machines: have certain automation capabilities, can meet the daily production needs of medium-sized enterprises, and are more common in some small processing plants.

(3) Large-scale fully automatic packaging machine production lines: usually used in large food processing enterprises, which have large production volumes and require high-speed, efficient and fully functional packaging equipment to cooperate with large-scale production.

Its core function is to package scattered peanut products according to the predetermined weight and specifications, making the products more convenient, hygienic and stable in storage, transportation and sales.

How does the peanut packaging machine work?

(1) Material preparation: First, the peanut products to be packaged must be transported to the storage hopper of the packaging machine. There are many ways to transport them. It can be transported by a conveyor belt, which can continuously and smoothly transport the peanuts; it can also be transported by a hoist, which is suitable for lifting peanuts at a low level to the height of the storage hopper; if the quantity is not large, manual loading is also a feasible method. The storage hopper has a certain capacity and can continuously supply materials for subsequent packaging. It is also equipped with a stirring device inside to prevent the peanuts from agglomerating and ensure uniform feeding.

(2) Quantitative packaging: When packaging begins, the metering device located below the storage hopper is activated. There are two common metering forms:

Volumetric metering: Peanuts are scooped using a container of fixed volume. This method is more suitable for products that do not require particularly high weight accuracy. It is relatively low in cost and simple to operate.

Weighing measurement: Relying on high-precision electronic scales, peanuts are accurately weighed according to the pre-set weight value, with extremely small errors, which can meet the strict requirements of high-quality products for weight accuracy.

(3) Bag forming: At the same time, the packaging material appears, usually a plastic film roll, which is slowly unwound from the unwinding mechanism. Through the mechanical action of the former, the originally flat film is rolled into a bag-like structure of a specific shape. Common bag types are:

Three-side sealed bag: three-side sealed, with good sealing, suitable for a variety of peanut product packaging.

Four-side sealed bag: four-side fully sealed, more solid packaging, can better protect the product.

Pillow bag: similar in shape to a pillow, more commonly used in some peanut product packaging that needs to be displayed flat, and convenient for stacking and storage. These bag types can adapt to different market packaging needs and product characteristics.

(4) Material filling: The peanut products that have been quantitatively measured are about to enter the packaging bag. They pass through the feeding channel and fall accurately into the newly formed packaging bag under the action of gravity or airflow. During this process, the filling speed and the moving speed of the packaging bag must be precisely matched to ensure that the peanuts are accurately loaded into the bag and avoid scattering outside the bag to cause waste or pollution.

(5) Sealing: After the peanuts are loaded into the bag, the packaging bag enters the sealing stage. The heat sealing device uses high temperature to tightly fit the bag mouth to form a sealed package, effectively blocking the entry of air and moisture.

Adding nitrogen to the peanut packaging machine

In the peanut packaging process, adding nitrogen is of great significance. Nitrogen is an inert gas with stable chemical properties and basically does not react chemically with peanuts. Before the sealing stage of the packaging machine, a special nitrogen injection device will be used to fill the packaging bag with high purity nitrogen to replace the original air. This brings two benefits:

Extending the shelf life: The nitrogen environment can inhibit the oxidation of the oil in the peanuts, greatly slowing down the speed at which the peanuts become rancid and taste bad, allowing the product to be sold on the shelf for a longer time.

Improving the appearance appeal: After being filled with nitrogen, the packaging bag will appear full and look more beautiful, which can attract consumers' attention on the shelf and promote sales.

How is the price of peanut packaging machine?

(1) The price of peanut packaging machines with different functions will vary, such as production output, special customization requirements, etc. Basically, the price of peanut packaging machines varies from small packaging machines to large packaging machine production lines. Basically, you can choose from a few hundred dollars to a few thousand dollars. Products from well-known brands have relatively high prices due to their reliable quality and perfect after-sales guarantee.

(2) When purchasing equipment, you must also consider the cost of supporting equipment, such as conveyor belts, elevators, etc., as well as additional expenses such as installation, commissioning, and training. Only by comprehensive consideration can you choose the peanut packaging machine that best suits your own business development.

With its efficient workflow and diverse functional characteristics, peanut packaging machines have provided strong impetus for the vigorous development of the peanut industry. Both small businesses and large enterprises can benefit from it according to their own needs, opening a new chapter in peanut product packaging.
