Coffee & Tea Manufacturing Industry Profile

Black tea manufacturing technology essentially involves disruption of the cellular integrity of tea shoots, thereby enabling the mixing up of substrates polyphenols and the enzymes polyphenol oxidases.

This results in the initiation of a series of biochemical and chemical reactions with the uptake of atmospheric oxygen and formation of oxidized polyphenolic compounds that are characteristic of tea along with volatile flavor compounds that impart characteristic aroma to tea.

Tea manufacturing is normally carried out in two ways, i CTC and ii orthodox. Enzymatic action is higher in the CTC type of manufacture. In orthodox type of manufacture, the withered leaves are rolled on specially designed orthodox rollers which twist and crush the leaves thereby rupturing the cells.

The maceration is less as against CTC processing. But this process results in teas with good flavor and aroma. The evaporation of moisture in the green leaf is brought about by blowing or moving air over the leaf in the withering trough.

The current of air performs a two functions viz. Currently in most of the south India tea factories trough withering is practiced. The dimensions of the trough in most of the factories vary considerably. However, nowadays wider troughs with two axial fans are preferred. Reasonably even — wither is achieved in wider troughs. The other fan supplies air just to control any heat developed.

So, in a well designed, balanced factory, an optimum load of 30kg per meter square for a peak crop anticipated in a single day has been the basis for the design of trough capacity. The good essence of withering is well ventilated withering lofts and access of drawing large volumes of air by the trough fans.

The ideal qualities of air required for withering are low dry bulb temperatures and high hygrometric differences with ample supply. The upward passage of air through the bed of leaves usually results in the bottom of the bed being withered first and the upper leaves last.

To achieve a more even wither turning over the leaf carefully once or twice is suggested. However, turning over may be practically difficult in wider open troughs. To achieve a more even wither turning over, reversible air flow systems have been practiced. Many of these difficulties have been overcome by using enclosed troughs.

In this system, the direction of air flow can be changed by a movable baffle plate either below or above the trough. Air space above the trough is totally enclosed. There are two sets of exit doors for the spent air; one set above the level of leaf and the other below. The system makes it possible to maintain fan efficiency and dispenses with the need for reversible fans.

Air heating system is also available to warm the air irrespective of the direction of air flow through the system. The other advantage is that a more uniform wither is achieved without the necessity of turning over and thereby the withered leaf is intact. It is important that pressure inside the plenum chamber should be constant throughout the length to have an uniform air flow rate. However, in the conventional troughs the pressure varies over the length for constant thick spreading.

A tapering cross section decreases the area towards the end and equalizes the pressure inside the plenum chamber. The method commonly employed to heat the air for withering are as follows: 1 direct use of hot air from the drier when it is empty, 2 hot air ducting to each trough with damper control from a separate heater, 3 hot water or steam based insitu radiators in each withering trough and 4 using exhaust air from the drier.

During normal conditions, it is always preferable to use ambient air as long as it has drying properties. If at all hot air is required, it would be ideal to use it during the early part of withering when the leaf is still turgid.

Warm air should not be used to wither during later stages, since the leaf takes a temperature nearing the dry bulb temperature. It would be better and more accurate to express the status of wither in terms of percentage of moisture content in the withered leaf.

If the percentage of moisture content at the end of withering is the same irrespective of moisture content of the green leaf, then by and large the physical condition will remain the same. Withering to constant moisture content every day is impractical even with the greatest care. The following two conditions are essential for good withering: storage of fresh leaf for a minimum period of nine hours is absolutely essential to allow chemical changes to take place whether a physical wither is desired or not, to make a product with required characteristics, this is referred to as chemical wither.

Physical wither is necessary for good fermentation. Green Leaf Sifting Extraneous matter such as stones, sand or metal pieces may find their way in the leaves brought into the factory; if such materials are fed into the fine-tuned, continuous machines, the moving parts will be severely damaged. Similarly if the leaves were not fed evenly into these machines, they could become jammed or would not function efficiently.

Hence green leaf sifting is essential prior to processing. The green leaf sifter is essentially a device for introducing a continuous even flow of withered leaf to the CTC processing section.

It is a vibrating tray, which is perforated with holes or is of a wire mesh. Powerful magnets have been provided in the green leaf sifter to remove any iron pieces present along with the leaf. Reconditioning: In South India, secondary grades and other residues which are obtained while cleaning the primary grades are ground and recycled with the withered leaf. This process is known as reconditioning. The primary objective of this practice is to produce grainy grades as well as tea of high density.

It also helps to minimize or eliminate secondary grade teas. The quantity of recycled material, known as recondition dust, varies from factory to factory, it depends on the quality of green leaf, the moisture content of the withered leaf and the standard of machinery available. The percentage of RC is mostly expressed on the weight of green leaf or made tea basis.

However, there is a wide variation in the moisture content of green leaf and thereby the quantity of made tea produced. So quantifying the amount of RC material for the made tea to be produced depending upon the green leaf conditions is difficult.

The best practice is that the amount of RC should be calculated on the withered leaf weight basis. Leaf Conditioning: The leaf shredder and rotor vane combination has been found to be ideal to pre-condition the leaf for CTC processing.

The output of both these machines should match with the CTC as well as drier capacities. Shredding of withered leaf into fine particles increases the rotorvane capacity and helps efficient mixing of the leaf with reconditioned dust in the rotorvane. To ensure this the shredder blades have to be changed every week. It is important that the weight of each blade should be less than one Kg. Reduction of gap between two blades progressively helps to achieve better results.

Rotorvane is essentially a large mincing machine and is imperative to precondition the leaf suitable to be fed into the CTC machine as well as for better fusion of RC material with withered leaf. There are two sizes, one with cylinder of The leaf is processed in this cylinder in which a rotor provided with vanes rotates between resistors thereby propelling the leaf forward and discharging through an end plate.

The leaf is distorted and shredded as it moves along the cylinder and cut into small pieces by the revolving cutter through which it must pass before it can leave through the apertures of an iris diaphragm. For good results the rotorvane should crush the leaf along with the RC dust at the maximum possible pressure.

In the larger rotorvane, a cone end plate is attached at the discharge end to increase the pressure; the leaf is discharged between the gap of the cone and the cylinder; the inner of the cylinder and cone are provided with battens in order to increase the efficiency of crushing. Rolling After preconditioning, the leaf is passed through four or five CTC machines arranged in tandem. The CTC machine essentially consists of two contra-rotating toothed rollers of equal diameters Depending upon the processing capacity required, rollers with different width are used i.

The two rollers rotate at different speeds. A slow speed roller; high speed roller ratio of with speeds between rpm and rpm have good effect. The slow speed roller acts initially as a conveyor apart from providing a surface for cutting. In order to derive the maximum benefit of a good cut, the drop point should be adjusted behind the crown of the slow speed roller, so that the leaf is conveyed into the cutting area. Otherwise, a portion of the leaf gets thrown over the high speed roller, thereby, losing the benefit of cut.

Even spaced, helical grooves are formed along the circumference by a standard angular milling cutter. The teeth are formed by cutting circumferential grooves on the roller which has the helical grooves. Each tooth has two longitudinal characteristics, the shoulder and the back slope. The ratio of the length of the shoulder to the back slope projection is known as the profile or style ratio which influences quality.

As a general rule, a style ratio of will produce a grainy tea with higher dust percentage. Quality CTC teas cannot be made if roller teeth are worn out or damaged.

It is, therefore, imperative that sharpening of segments is done precisely and on schedule. The speed of the high speed and low speed roller in conventional CTC roller will be to and 70 to 75 RPM, respectively. The linear speed difference between the rollers should be checked periodically to enhance the appearance of made tea and to improve the recovery percentage. Difference in the diameter of rollers leads to different speed in rollers. The pulley size also influences the speed.

To achieve ratio, proper matching of equal diameter rollers is essential. Rotation of the fermentation drum facilitates granulation of the tea particles and increases the bulk density which is desirable for south Indian CTC teas.

In drum fermentation, the whole process is dynamic and the leaves are constantly rotating. Every bit of tea that is being fermented is constantly layered and exposed to the fresh air or conditioned air. Rubbing of leaf against leaf takes place and the juices present in the micro cells of leaf are evenly coated on the exterior of the tea leaf.

Drum fermentation produces blacker teas as compared to floor fermentation. These teas are usually brisker due to better aeration. Since most of the biochemical reactions occurring during fermentation are oxidative in nature, mass transfer of oxygen to the tea particle is a critical parameter in the design of any fermentor.

The fermenting drums are equipped with spiral flights on the interior for lifting and showering the solids through the air stream and to accelerate the forward flow in the drum.

Good ventilation and access to fresh air are paramount to proper fermentation. In most of the factories, the air required for fermentation is drawn from the rolling room. This results in recycling of spent air for fermentation which is not advisable. It is suggested to have a co-current air flow arrangement in the fermenting drum; the blower type is preferable to the suction type of fan.

Manufacturing is the production of products for use or sale using labour and machines , tools , chemical and biological processing, or formulation, and is the essence of secondary industry. The term may refer to a range of human activity, from handicraft to high tech , but is most commonly applied to industrial design, in which raw materials from primary industry are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other more complex products such as aircraft , household appliances , furniture , sports equipment or automobiles , or distributed via the tertiary industry to end users and consumers usually through wholesalers , who in turn sell to retailers , who then sell them to individual customers. Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product. The manufacturing process begins with the product design, and materials specification from which the product is made.

Companies in this industry roast coffee, blend tea, and manufacture coffee and tea concentrates. World coffee production is more than 10 million metric tons per year. Top producers include Brazil, Vietnam, Colombia, and Indonesia. Tea production is about 6 million metric tons.

This is still agreed by most experts to produce the best black tea. Even with the technological improvements introduced over the last thirty or forty years, the orthodox method is relatively slow and labour-intensive; but as the tea planters and traders of Sri Lanka have always maintained, good tea cannot be hurried. Nor, oddly enough, can it be delayed. The time devoted to each of the processes of tea manufacture has to be finely judged if a quality product is to be obtained. Plucking calls for discrimination and dexterity and is carried out mainly by women. Fiddly work, but a skilled tea-plucker can collect up to 20kg.
