Peanut Air Blanching Machine is a kind of equipment specially used for making Blanched Peanut.

1. Working principle

Peanut Air Blanching Machine mainly uses the power of compressed air to achieve peanut blanching. When the peanuts enter the working area inside the machine, they are impacted by high-speed jet compressed air through a specific airflow channel. Under the impact of this powerful airflow, the peanut shell will fall off the peanut kernel. This method is relatively gentle. Compared with some traditional mechanical friction peeling equipment, it can reduce the damage to the peanut kernel to a certain extent and maintain the integrity of the peanut kernel.

2. Structural composition

Feeding device: used to evenly transport peanuts to the peeling area. Its design usually takes into account factors such as the size and shape of the peanuts to ensure the stability and continuity of the feed. For example, some feed ports will have an inclined channel, and the width and depth of the channel can adapt to the size of the peanuts to prevent the peanuts from being blocked or unevenly stacked during the feeding process.

Air compression system: This is one of the core parts of thePeanut Air Blanching Machine. It includes components such as air compressors, air storage tanks, and air delivery pipelines. The air compressor compresses the air to a certain pressure and stores it in the air tank, and then transports the compressed air to the blanching work area through a pipeline. The pressure of the compressed air can be adjusted according to factors such as the variety of peanuts and the hardness of the red skin, The general pressure range is between 0.4 and 0.8 MPa.

Blanching room: Peanuts are subjected to the impact of compressed air here to complete the blanching process. The internal structure design of the blanching room is also critical. There are usually special airflow guide devices to enable the compressed air to act evenly on the peanuts. For example, there may be spiral guide grooves on the wall of the blanching room to guide the airflow to form a rotating airflow field, so that the peanuts can be impacted by air in all directions, thereby improving the peeling efficiency.

Separation system: used to separate the peeled peanut kernels and peanut shells. Common separation methods are a combination of wind separation and screening separation. In wind separation, due to the different physical properties of peanut kernels and peanut shells such as weight and shape, their flight trajectories and settling speeds are also different under the action of airflow. Lighter peanut shells will be blown to a farther location, while heavier peanut kernels will fall closer. Screening separation is to further separate the peanut kernels and peanut shells through screens with different apertures.

Discharging device: collect and output the blanched peanut kernels. The discharge port generally has an adjustable flow control device that can control the discharge speed of the peanut kernels according to the actual production needs.

3. Advantages

High efficiency: can process a large amount of peanuts in a short time. For example, some large Peanut Air Blanching Machine can process hundreds of kilograms or even tons of peanuts per hour, greatly improving production efficiency.

High peeling quality: less damage to the peanut kernels, can maintain the good appearance and quality of the peanut kernels, and provide high-quality raw materials for subsequent peanut processing, such as peanut butter, peanut candy, etc.

Sanitary and environmental protection: The entire blanching process mainly uses air, which avoids the mixing of impurities such as metal debris generated by friction in the traditional mechanical blanching process into the peanut kernels, and reduces the direct contact between mechanical parts and peanuts, which is more in line with the hygiene standards of food processing. At the same time, compared with some chemical blanching methods, no harmful chemical waste will be generated, which is more environmentally friendly.

4. Scope of application

The Peanut Air Blanching Machine is suitable for various peanut processing enterprises, including peanut food processing plants, oil processing plants, etc. In peanut food processing plants, it is used to produce peanut snack foods, such as salt-baked peanuts, flavored peanuts, etc.; in oil processing plants, it provides blanched peanut kernels for peanut oil extraction to improve the quality of peanut oil.

In conclusion, Peanut Air Blancher is your new choice for your business
