Rice milling removes the husk, bran, and germ from brown rice to achieve white rice. It is an energy-consuming and time-consuming process. Rice mill machinery is used to efficiently and effectively complete this process. This machinery includes high speed, heavy-duty roller mills, pneumatic separators, importers, fan blowers, air cleaners, grain dust collectors, adjustable belt conveyors, etc. To extend the life span of the rice mill, regular maintenance is required.

Let us first discuss the upkeep of rice mills. The process of rice milling can be divided into sub-tasks:

  1. Moisture testing at regular intervals

  2. Cleaning the whitening room

  3. Checking machinery parts & supportive parts

Rice Mill Machinery Process

Let's discuss the rice milling process in detail to understand better.

1. Moisture testing at regular intervals

Moisture control is the most critical maintenance task in rice mills. An increase in the water content of rice can increase the amount of broken rice. The rice mill machinery must maintain a certain level of dryness. The water content should not surpass 14 - 15%.

What will happen in case you ignore this process?

• Increase in the amount of broken rice grain

• Affected rice quality

• Increase in power consumption

2. Cleaning the whitening room

The rice milling process tends to contaminate the rice with impurities from the storage facility, machines, or human handling. The rice must be screened to prevent contaminants from entering the rice during the final packaging stage. Rice mill maintenance personnel will vibrate the sieve of the rice to remove impurities smaller than five millimeters.

What will happen in case you ignore this process?

• The rice screen will damage.

• Might cause blockage in the whitening room

3. Checking machinery parts & supportive parts

Before starting the machine, regularly check the rice mill metal components such as the rice sieve, rice knife, and cylinder core.

What will happen in case you ignore this process?

• Accidents may occur if the bolts and nuts are not tightened.

Rice Mill Machinery & Rice Milling Processing Guide

Various types of rice mill machines are available to complete the rice milling process. A rice mill is a food processing arrangement and facility that converts raw paddy into rice. Rice is harvested from paddy fields, milled, and processed using modern machinery.

Application of Rice Mill Machinery

Milling is a critical step in the rice production process. It is usually done after the rice has been harvested. Paddy grown industrially cannot be devoured in its natural state. This is why paddy is milled after it has been harvested.

Rice milling uses a rice mill machine, which can easily remove impurities from rice. Milling is primarily defined as a substance removal process used to remove unwanted rice material. Rice milling equipment, workpiece, fixture, and cutter are required for the milling process.

The workpiece, which is secured to the fixture, is one of the essential aspects of a milling machine. It is then placed on the milling machine's platform. The milling machine's cutter is packed with sharp teeth and spins at high speed. It is also protected within the milling machine. Both the workpiece and the cutter are active at the same time.

The mixture is placed into the rotating cutter after being fed to the workpiece. The rotating cutter cuts the material, dropping off small chips to create the desired shape. Milling aids in producing three-dimensional rice that may or may not be axially symmetrical.

Rice Mill Spare Parts

Rice mill machinery comes in a variety of sizes and shapes, depending on the type of procedure and the end product that must be produced. The two most important things in every milling process, the workpiece and the cutter, virtually remain the same.

The milling operations include the following components:

• Base and column: This is one of the milling machine components that settles on the ground and supports the machine. It has a sizable column that connects to the other components and is attached to the base.

• Table: A table is when the workpiece is assembled on the platform. It has a T-shape and is attached along its ground. It is clamped directly on the three slots after being secured with the vise.

• Saddle: A component of the table that allows the milling machine to move longitudinally. It can also move along with another platform called the knee in the horizontal section of the workpiece in the Y direction.

Rice Milling Method

Before beginning the process cycle, you must understand what milling is all about. The total time needed to produce rice includes two components: initial setup time and cycle time for each part.

A milling machine's setup time includes operating the rice mill machinery, planning all tool movements, and installing the fixtures.

Four factors determine the cycle time:

• The load and unload time: It takes time to load the workpiece into the machine and secure it with the fixture. It also includes the time required to unload the completed part. The load time of a milling machine varies depending on the size, weight, complexity of the workpiece, and type of fixture.

• The cut time: is the amount of time it takes to make all of the necessary cuts in the workpiece with the cutter for each operation. To determine the cut time for any operation, divide the total cut length for the operation by the feed rate. This indicates the cutter's operation speed concerning the workpiece.

• The ideal time: In a milling operation, it is also referred to as non-productive time. This is the point in the milling process when neither the workpiece nor the cutter is active. This includes all processes such as the tool approaching and retracting from the workpiece, tool movements between features, the time required for machine settings adjustment, and tool changing.

• The tool replacement time: This is the time required to replace a tool that has outlived its useful life and has worn out effectively. This time is not included in the entire operation and is only considered when the tool has reached the end of its useful life. This time must be adjusted throughout the milling process.
