Tea Powder Business Basics
Before diving into the intricacies of the tea powder manufacturing process, it’s important to understand the basics of tea processing and the machinery involved in tea production.
Understanding Tea Processing
Tea processing involves a series of carefully controlled steps that transform freshly picked tea leaves into the final product. The traditional method of tea processing, known as the orthodox method, consists of four stages: withering, rolling, oxidation, and drying (Twinings).
-
Withering: The first step in tea processing is withering, which reduces the water content of the tea leaves. This is typically done by spreading the leaves out in a controlled environment with proper ventilation. Withering reduces the water content to about 60%-70% and prepares the leaves for the next stage.
-
Rolling: Once the leaves have withered, they undergo rolling. During this stage, the tea leaves are twisted and turned until they become thin and wiry. Rolling helps to shape the leaves, release enzymes, and initiate the oxidation process.
-
Oxidation: Oxidation is a crucial step that changes the color, taste, and strength of the tea. The oxidization process is carefully controlled and involves allowing the tea leaves to react with oxygen in a controlled environment. The degree of oxidation determines the type of tea produced, whether it’s green, oolong, black, or white.
-
Drying: The final stage of tea processing is drying. After oxidation, the tea leaves are dried to reduce the moisture content to about 3%. Drying helps to stop further oxidation and preserve the tea’s flavor and aroma.
It’s important to note that variations of these processing techniques exist, depending on the type of tea being produced. For example, the CTC (Cut, Tear, Curl) method is often used to produce tea powder for tea bags. This method involves withering the leaves, passing them through rollers with sharp teeth that cut, tear, and curl the leaves into tiny granules, and then subjecting them to oxidation and drying similar to the orthodox method (Twinings).
Machinery Used in Tea Production
Tea production relies on a range of specialized machinery that plays a crucial role in each step of the manufacturing process. Some of the key machinery used in tea production includes:
-
Withering Troughs: These are large trays or troughs used for withering the tea leaves. The troughs provide a controlled environment with proper ventilation to facilitate the withering process.
-
Rolling Machines: Rolling machines are used to twist and turn the tea leaves during the rolling stage. These machines help shape the leaves and release enzymes that contribute to the tea’s flavor and aroma.
-
CTC Machines and CTC Rollers: CTC machines, which stands for Cut, Tear, Curl, are specialized equipment used for the CTC method of tea production. CTC rollers with sharp teeth cut, tear, and curl the tea leaves into granules suitable for tea bags.
-
Dryers: Dryers are used to reduce the moisture content of the tea leaves during the drying stage. These machines carefully control the temperature and airflow to ensure proper drying without compromising the quality of the tea.
Different tea production methods may require variations of these machines to suit the specific processing techniques employed. The use of machinery in tea production has evolved over time, allowing for greater efficiency and consistency in the manufacturing process.

Tea Powder Manufacturing Process
The manufacturing process of tea powder involves several essential techniques to ensure the desired flavor, aroma, and quality of the final product. Let’s explore the key steps involved in the tea powder manufacturing process: withering and rolling techniques, oxidation and fermentation methods, and the fixing and drying process.
Withering and Rolling Techniques
The first step in tea powder production is withering. During this stage, freshly plucked tea leaves are spread out in a well-ventilated area to reduce their water content. Withering typically reduces the water content of the tea leaves to about 60%-70% Twinings. This process helps to soften the leaves and prepare them for the subsequent rolling stage.
After withering, the tea leaves undergo the rolling technique. Rolling involves twisting and turning the leaves until they become thin and wiry. This step helps to break down the cell walls of the leaves, which initiates the release of enzymes responsible for the oxidation process. The rolling technique also shapes the tea leaves, giving them their characteristic appearance.
Oxidation and Fermentation Methods
Oxidation is a crucial step in the tea powder manufacturing process, as it plays a significant role in determining the color, taste, and strength of the final tea product. The extent of oxidation can vary depending on the type of tea desired. Oxidation occurs when the enzymes released during rolling react with the oxygen in the air.
The level of oxidation is carefully controlled to achieve the desired characteristics of different tea varieties. For example, black tea undergoes full oxidation, resulting in its dark color and robust flavor. On the other hand, green tea is minimally oxidized, preserving its natural green color and delicate flavor.
In some tea production methods, such as oolong tea, oxidation is followed by a fermentation process. Fermentation helps to further develop the flavor and aroma compounds in the tea leaves. This step is critical in creating the unique characteristics of oolong tea.
Fixing and Drying Process
After the desired level of oxidation and fermentation is reached, the tea leaves go through the fixing process. Fixing involves exposing the leaves to high temperatures to halt the oxidation or fermentation. The heat deactivates the enzymes responsible for oxidation, ensuring that the tea maintains its desired flavor profile.
Following fixing, the tea leaves undergo the drying process. Drying is essential to reduce the water content of the leaves to about 3% Twinings. It helps to preserve the tea’s shelf life by inhibiting the growth of microorganisms and preventing moisture-related issues.
The fixing and drying process can be carried out using various methods, including sun drying, pan firing, or using specialized drying equipment. The choice of method depends on the type of tea being produced and the desired characteristics of the final product.
By understanding the withering and rolling techniques, oxidation and fermentation methods, as well as the fixing and drying process, one can appreciate the intricate steps involved in the tea powder manufacturing process. Each stage contributes to the unique flavors, aromas, and qualities that make tea an enjoyable and diverse beverage.
Types of Tea Powder
Tea powder comes in various types, each with its own unique characteristics and production methods. Understanding the different types of tea powder is essential for those in the beverage business. Let’s explore four popular types: green tea production, oolong tea processing, white tea manufacturing, and the unique method used for purple tea.
Green Tea Production
Green tea is one of the most widely consumed and recognized types of tea powder. Its production involves fixing the leaves early on during the process to preserve the green color and lighter taste, usually right after plucking. This step helps retain high levels of antioxidants and health benefits associated with green tea.
In China, the production of green tea follows the rule of “two leaves and the bud.” After plucking, the leaves are withered on laths covered with jute, wire, or nylon nets. They are then heated in wok-like pans, rolled, and dried in special dryers (Dethlefsen & Balk). Green tea leaves are not oxidized during processing, giving them their light, fresh flavor and delicate color. They are often pan-dried or steamed to prevent oxidation and rolled into various shapes like little bullets or tightly wound spirals (Twinings).
Oolong Tea Processing
Oolong tea is a partially oxidized tea powder that sits between green tea and black tea in terms of oxidation levels. The production process of oolong tea involves withering, tossing or shaking the leaves to bruise the edges, oxidizing the leaves in sunlight or indoors, and finally, firing or roasting the leaves to halt the oxidation process. The degree of oxidation can vary, resulting in a wide range of flavors and aromas, from light and floral to dark and rich (Justea).
Oolong tea production methods can differ depending on the specific type and region. Some oolong tea leaves are bruised to a greater extent, allowing for a higher level of oxidation, while others are lightly bruised to retain more of their green tea characteristics. The firing or roasting step helps to develop the unique flavors associated with oolong tea.
White Tea Manufacturing
White tea is the least processed type of tea powder, known for its delicate flavor and pale color. The production process involves minimal oxidation and handling to preserve the natural characteristics of the tea leaves. The leaves are typically plucked when they are young and covered with fine white hairs, hence the name “white tea.” After plucking, the leaves are withered and dried, often in the sun or under controlled conditions. This minimal processing allows the delicate flavors and subtle aromas of the tea leaves to shine through (Justea).
White tea leaves are not rolled or shaped during processing, making them appear more natural and less uniform compared to other types of tea powder. This natural appearance adds to the charm and appeal of white tea.
Purple Tea Unique Method
Purple tea is a relatively new variety of tea that stands out due to its purple-colored leaves. This unique type of tea powder is primarily cultivated in Kenya. Purple tea leaves undergo a similar processing method as green tea, with slight variations in oxidation levels. The leaves are carefully plucked, withered, fixed, rolled, and dried. The result is a tea powder with a distinct purple hue and a flavor profile that combines the characteristics of green and black tea.
The production of purple tea showcases the versatility and innovation within the tea industry. As purple tea gains popularity, more research and development are being conducted to explore its potential health benefits and flavor profiles.
Understanding the different types of tea powder is essential for those in the beverage business. Each type has its own production methods, flavors, and characteristics, allowing for a diverse range of options for tea enthusiasts.
