CTC (Crush, Tear, Curl) black tea is a type of tea that is manufactured using a machine that crushes, tears, and curls the tea leaves to produce small, hard pellets. Here are the general steps involved in black tea manufacturing (CTC black tea):
1. Plucking: The process starts with the plucking of fresh tea leaves. The quality of the tea depends on the quality of the leaves, so only the young, tender leaves and buds are plucked.
2. Withering : The plucked leaves are spread out on large trays or racks to wither for several hours. During this time, the leaves lose moisture and become limp, making them easier to manufacturing process.
3. Rolling : The withered leaves are then rolled to break their cell walls and release the juices inside. This is typically done using a machine that applies pressure to the leaves.
CTC black tea manufacturing process: The dried leaves are then fed into a CTC machine, which crushes, tears, and curls them into small, hard pellets. This black tea manufacturing process breaks the leaves down into tiny pieces and releases more of their flavor and aroma.
4. Fermentation : The rolled leaves are spread out and allowed to ferment for a few hours. This process involves exposing the leaves to a specific level of humidity and temperature to promote oxidation, which darkens the leaves and gives them their characteristic flavor and aroma.
5. Drying : Once the leaves have been fermented, they are dried to stop the oxidation process. This is typically done using large hot air dryers or ovens.
6. Sorting and Grading: The final step in the black tea manufacturing process involves sorting the pellets by size and quality. The pellets are graded based on factors such as color, flavor, aroma, and texture.
Once the tea has been sorted and graded, it is packed into bags or other containers and shipped to tea wholesalers and retailers.
Plucking:-
Plucking is the process of harvesting fresh tea leaves from the tea plant, usually by hand. The plucking of tea leaves is an important step in the production of tea, as it directly affects the quality of the final product.
In general, the tea leaves are plucked from the top two leaves and the bud of the tea plant. These leaves are the youngest and most tender parts of the tea plant, and they are believed to produce the best quality tea. The plucking process is typically carried out in the early morning, as the leaves are at their freshest and have not yet been exposed to the sun.
The plucking of tea leaves can be done by hand or by machine, depending on the size and location of the tea plantation. Hand plucking is often preferred for high-quality teas, as it allows for greater control over which leaves are harvested. Machine plucking, on the other hand, is faster and more efficient, but it can be more damaging to the tea plant and can result in lower-quality tea.
After the tea leaves are plucked, they are typically transported to a black tea processing facility, where they will undergo a series of steps to be dried, rolled, and oxidized before they are ready to be packaged and sold as tea.
Withering:-
Withering is an important step in the processing of certain crops, particularly tea leaves. During this process, the freshly plucked leaves are spread out on large trays or racks and allowed to wither for several hours.

The purpose of withering is to remove excess moisture from the leaves, which helps to initiate the enzymatic oxidation process that is responsible for developing the unique flavor and aroma of the finished product. The withering process also makes the leaves more pliable and easier to handle during subsequent processing steps.
The length of time required for withering can vary depending on factors such as the type of crop being processed, the ambient temperature and humidity, and the desired end product. Once the leaves have been withered to the appropriate degree, they may be further processed through techniques such as rolling, oxidation, and drying to produce the final product.
Rolling:-
Rolling is a process used in the production of certain types of tea, such as black tea and oolong tea. After the leaves are withered, they are rolled to break their cell walls and release the juices inside. This helps to initiate the oxidation process, which is a key step in the production of black and oolong teas.
Rolling can be done by hand or by machine. Hand-rolling is a traditional method that is still used in some tea-producing regions, particularly for high-quality teas. Machine-rolling is faster and more efficient, but may not produce the same level of quality as hand-rolling.
The degree of rolling can also vary depending on the desired outcome. Lighter rolling may produce a more delicate flavor, while heavier rolling can result in a stronger, more robust flavor.
After rolling, the tea leaves may be allowed to oxidize further before being dried and processed into their final form. The specific black tea manufacturing process can vary depending on the type of tea being produced.
CTC processing:-
CTC processing, short for "Crush, Tear, Curl" processing, is a method used to produce tea that is commonly used in large-scale tea production. The process involves feeding the dried tea leaves into a CTC machine, which mechanically crushes, tears, and curls them into small, hard pellets.
The CTC machine is made up of a series of cylindrical rollers with serrated edges that rotate at high speed. The dried tea leaves are fed into the machine, where they are crushed and torn by the rollers, before being twisted and curled into small, hard pellets. The pellets produced by the CTC process are uniform in size and shape, which makes them ideal for use in tea bags.
CTC processing is a highly efficient method of tea production, as it can process large volumes of tea quickly and consistently. The resulting tea is known for its strong flavor and briskness, and is commonly used in blends for mass-market teas. However, some tea connoisseurs consider CTC tea to be of lower quality than other types of tea, such as whole leaf tea, as the process can strip the tea of some of its delicate flavors and aromas.
Fermentation:-
Fermentation is a process that is commonly used in the production of certain food and beverage products, including tea. In the context of tea production, fermentation refers to the natural chemical changes that occur in the tea leaves as they are allowed to rest and oxidize after being harvested.
After tea leaves are harvested, they are typically rolled or crushed to release their natural juices and enzymes. These rolled leaves are then spread out and allowed to rest in a warm, humid environment for several hours, during which time they undergo a process of natural fermentation.
During fermentation, enzymes within the tea leaves begin to break down the complex chemicals and compounds present in the leaves, causing them to undergo a series of chemical changes. These changes result in the characteristic flavors, aromas, and colors associated with different types of tea.
The length and intensity of the fermentation process can vary depending on the desired final product. For example, black teas are typically fermented for a longer period of time than green teas, which are typically only allowed to rest for a short period before being heated or dried to stop the fermentation process.
Drying:-
It is true that once tea leaves have been fermented, they are dried to stop the oxidation process. Drying the leaves helps to preserve their flavor and aroma by removing any excess moisture.
There are several methods for drying tea leaves, including sun-drying, oven-drying, and machine-drying. Sun-drying is a traditional method that involves spreading the leaves out on bamboo mats and allowing them to dry in the sun. Oven-drying involves using an oven or a dryer to remove moisture from the leaves, while machine-drying uses specialized equipment to dry the leaves quickly and efficiently.
Regardless of the method used, it is important to ensure that the leaves are dried thoroughly to prevent mold and other types of spoilage. Once the leaves have been dried, they are ready to be sorted and packaged for sale.
Sorting:-
Sorting and grading are important steps in the black tea manufacturing process of pellets as they ensure that the final product is consistent in terms of size and quality.
During the sorting process, the pellets are separated according to their size. This is done using a machine called a sieve, which uses a mesh to separate the pellets by their diameter. The pellets that are too small or too large are separated from the batch and sent for reprocessing or disposal.
Grading, on the other hand, involves sorting the pellets according to their quality. The pellets are inspected for defects such as cracks, discoloration, or other imperfections that may affect their performance. The pellets that pass the quality test are graded as premium, while those that have defects are graded as standard or low quality.
The sorting and grading process helps to ensure that the final product meets the required specifications and standards. It also ensures that customers receive a consistent and high-quality product.
Black Tea manufacturing is a complex process that involves several stages, including plucking, withering, rolling, oxidizing, and drying.
