Parboiled rice is a type of rice that has undergone a hydrothermal treatment process before milling. This process improves the nutritional value, appearance, and cooking quality of rice. Parboiled rice is popular in many countries, especially in Africa, Asia, and Latin America.To produce parboiled rice, you need a paddy boiling machine, which is a key equipment for the parboiling process. In this article, we will introduce what a paddy boiling machine is, how it works, and what benefits it can bring to your rice business.

What is a Paddy Boiling Machine?

A paddy boiling machine is a machine that uses steam or hot water to cook the soaked paddy. The cooking process gelatinizes the starch in the rice grains, making them harder and more translucent. The cooked paddy is then dried and cooled before milling.

A machine can be divided into two types: batch type and continuous type. A batch type paddy boiling machine cooks a fixed amount of paddy at a time, while a continuous type paddy boiling machine cooks the paddy continuously with a conveyor belt.

A machine usually consists of several parts, such as:

• A soaking tank that immerses the paddy in water for several hours to increase its moisture content.
• A steaming and boiling tank that heats the soaked paddy with steam or hot water to gelatinize the starch.
• A drying and cooling section that reduces the moisture content and temperature of the cooked paddy.
• A control panel that regulates the temperature, pressure, time, and speed of the parboiling process.

How Does a Paddy Boiling Machine Work?

The working principle of a paddy boiling machine is simple and straightforward, the basic steps are as follows:

• A machine cleans and de-stones the raw paddy to remove any impurities and foreign materials.
• The machine soaks the cleaned paddy in water at a certain temperature and time to increase its moisture content to about 30%.
• The machine steams and boils the soaked paddy with steam or hot water at a high temperature and pressure to gelatinize the starch in the grains.
• The machine dries and cools the steamed and boiled paddy with hot air or natural air to reduce its moisture content to about 14%.
• The dried and cooled paddy is ready for milling or storage.

What are the Benefits?

A machine can bring many benefits to your rice business, such as:

• It can improve the quality and value of your rice products. Parboiled rice has higher nutritional value, longer shelf life, better appearance, and easier cooking than ordinary white rice.
• It can increase your rice yield and reduce your production cost. Parboiled rice has less breakage, less wastage, and less energy consumption than ordinary white rice.
• It can save your labor, time, space, and environment. A machine can automate the parboiling process, save your manpower and working hours, occupy less land area, and produce less pollution.
