Rice Mill Machinery

There are various types of rice mill machines to complete rice milling process

Rice Mill Machine Application

Milling is one of the most important steps in the production of rice. It is generally performed post the production of rice. The paddy produced industrially cannot be consumed in its natural forms.

This is why paddy is processed post its production, by the process of milling. It removed in order to make it fit for human consumption.

Rice Milling employs the usage of rice mill machine that can easily remove the impurities from rice.

Types of Rice Milling Machines

There are a variety of operations that have to be performed during milling in order to make rice fit for the process.
Rice Mills includes following Processes:

  • Mini Rice Mill
  • Rice Polisher
  • Paddy Separator
  • Paddy Cleaner
  • Rice Huller
  • Rice Whitener
  • Rice Grader
  • Paddy Dehusker
  • Rice Destoner
  • Rice Cleaning Machine
  • Rice Length Grader
  • Rice Flour Mill
  • Paddy Dryer Plant
  • Paddy Parboiling Plant
  • Pneumatic Rubber Sheller
  • Husk Aspirator
  • Rice Plansifter
  • Thickness Grader
  • Rice Dehusking Machine
  • Rice Bran Centrifugal Separator
  • Rice Mill Dryer
  • Rice Pulverizer

The Rice mill process starts with the cleaning of the paddy and lasts until the packaging of the rice.

Milling is mainly defined as a material removal process that is used to remove the
unwanted material of rice. The milling process requires rice milling machinery,
workpiece, fixture, and cutter. The workpiece is one of the most important
components of a milling machine and is secured to the fixture. It is then added to the platform inside the milling machine.

The cutter in the milling machine is packed with sharp teeth and rotates at a very
high speed. It is also secured inside the milling machine. The workpiece and the
cutter work simultaneously.

The material is first to feed to the workpiece which is then fed into the rotating cutter. The material is cut with the rotating cutter which then falls off as small chips to create the desired shape. Milling aids in generating three-dimensional rice that might not be axially symmetrical.

Rice Mill Machinery Parts

Rice Mill machines are available in the various sizes and shapes depending on the type of operation and the end product that has to be performed. The two most important things, the workpiece, the cutter practically remain the same in every milling process. The following are the components in the milling operations:

Base and column:-

This is one of the components in the milling machine that sits on the ground and is required to support the machine. It has a large column that is attached to the base and is connected to the other components.

Table:-

When the workpiece is mounted on the platform, that is called a table. It sits in a T form and is attached along its surface. It is secured with the vise and then can be clamped on the three slots directly.

Saddle:-

It is also a part of the table that allows the milling machine to move in the longitudinal motion. It can also move in the horizontal section of the workpiece in the Y direction along with other platform called the knee.

Knee:-

It supports the saddle and the table in all the milling operations. It can also be referred to as the column and aids in the vertical motion of the workpiece. It can move vertically when the cutter is stationary. When the cutter is moving in the vertical direction, then the cutter is stationary. This aids in cutting the workpiece and effective milling operation.

Rice Milling Process

It is very important that you know what milling is all about before you start the process cycle. The total time required to produce rice includes two things, one is the initial setup time and the other is the cycle time for each part.

The setup time of a milling machine includes the time required to make its operation, plan all the tool movements and install the fixtures in the milling machine. The cycle time, however, is depended on four things:

The load and unload time:

This is the time required to load the workpiece into the machine and then secure it with the fixture. It also includes the time to unload the finished part. The load time is different in different milling machines depending on the size, weight, complexity of the workpiece and the type of fixture.

The cut time:-

It is the amount of time taken to make all the necessary cuts with the help of the cutter in the workpiece for each operation. In order to calculate the cut time for any operation, you have to divide the total cut length for the operation with the feed rate. This gives the operation speed of the cutter relative to the workpiece.

The ideal time:-

It is also defined as the non-productive time in a milling operation. This is the time when neither the workpiece nor the cutter is engaged in the milling process. This includes all those processes like the tool approaching and retracting from the workpiece, tool movements between features, the time required for adjustment of the machine settings and the changing tools.

The tool replacement time:-

This is the amount of time required to replace a tool that has exceeded its time of operation and has worn out effectively.

This time isn’t included in all the operation and is taken into consideration when the tool has reached its lifetime. This time has to be adjusted in the entire milling process.

Rice Milling Operation Cost

There are three different types of cost drivers in the rice mill operation.

Material cost:-

This is determined with the help of the quantity of the stock and the unit price of it. This determines the workpiece, size, stock size, method of cutting the stock and the production quantity of it.

Production cost:-

This is a result of the total production time and the hourly rate. This includes the setup time, load time, cut time, idle time and the tool replacement time. The entire production cost is dependent on the skill of the operator.

Tooling cost:-

This is determined by the total number of cutting tools required and the unit price for each tool. There are a number of unique tools that are required for the various operations to be performed. With the daily uses of the tools, the lifetime of a tool is reduced.

Final Thought

Rice milling is one of the important processes & modern rice mill machines are required for the proper dimension of the rice that is prepared.
