  • The design of the flour packing machine
  • The automation level of the flour packing machine
  • Based on flour packing machine design

Inline flour packing machine

The type of flour packing machine which uses an Inline design will pack products in straight and orderly lines. This means that the starting and finishing points of the operating machine are located at the lines opposite end. This type of packing machine design has only single input and output lanes.

The major drawback of this type of design is that it requires ample floor space for its installation. But some packagers still prefer the Inline packing machine because it is easier to inspect each packaging station in these designs. This type of design enhances visibility and makes it easier to check all packages.

Rotary flour packing machine

This type of machine has circular designs; the operation is performed in a circular motion, giving the operator an ergonomic format. Therefore, the Rotary flour packing machine does not occupy ample space to operate. It can easily be confined to a small area without affecting the outcome of the product. Also, the starting and ending points of the operation in the Rotary machine design are close to each other.

For higher production requirements, Rotary flour packaging machines are vastly used. They feature one to four in-feed lanes, but the one-lane machine design is more common and used mainly by entrepreneurs.

Apart from the lanes, there are permanent stations in the rotary flour packing machine. These permanent stations are embedded circularly. Each station performs a selected procedure within the packaging process. These stations can vary from one machine to another, but there will be eight stations.

Based on automation of flour packing machine

Fully automatic flour packing machine

In this design of flour packing machine, the machine will not need monitoring or operation from a human being throughout the whole procedure. The operator just had to enter the appropriate parameters in the machine, and it will do the rest of the job. Moreover, these machines have sensors that help different coordinate pieces of equipment of the machine during the whole packaging process.

For example, the sensor detects if a predetermined fill level is reached, and then it signals the machine to stop the further filling of the package. With the help of these sensors, the whole process of filling and packaging will run automatically and continuously. It will also reduce the human errors caused by manual packaging.

Semi-automatic flour packing machine

This packing machine needs the operator to manually put the pouch or bag in the machine and initiate the packaging process. As the name suggests, some procedures of Semi-automatic machines will work automatically, but the majority of the processes still rely on the operator.
