The outline below details these steps at each stage of the process. Farm workers pick usable tea leaves from the field. Picked tea leaves are weighed and grouped into 50 kg bags. Bags of weighed tea are moved to a processing area. Processing Bags of tea are reweighed at the processing facility. Tea leaves are spread across pans and troughs. Tea leaves are withered on pans. Tea leaves are cooled. Tea leaves are removed from pans and reweighed. Tea leaves are moved onto special trays and put through a rolling machine. Tea leaves go through their first drying. Tea leaves are cooled. Tea leaves are removed from special rolling trays and put into new trays to go through a second drying machine. Tea leaves are removed from trays and reweighed; poor-quality leaves are thrown away. Tea leaves are visually inspected. Poor-quality leaves are discarded. Tea leaves are moved to an oxidizing area. Tea leaves are oxidized. Tea leaves go through their final drying to complete the oxidation process. Tea leaves are cooled. Tea leaves are sent to packaging and shipping. Packaging and shipping involve weighing tea leaves, sorting through machines to discard misshaped or discolored leaves, sealing into paper tea bags, wrapping, sealing, sorting into packs, and preparing for shipment. Shipping boxes are wrapped and sealed, ready to be shipped.

The production workflow for tea encompasses a series of meticulously coordinated steps designed to ensure the quality, efficiency, and sustainability of tea production. These steps range from initial harvesting of tea leaves to the final packaging and shipping of the finished product, with particular emphasis on quality control and waste minimization. Integrating principles from lean manufacturing and sustainable practices enhances these processes, aligning the production with modern environmental standards and consumer expectations.

Initially, farm workers undertake the harvesting of tea leaves from designated fields. This phase demands careful selection to ensure only the best quality leaves are picked, forming the foundation for high-quality end products. The harvested leaves are weighed and grouped into standard 50 kg bags for ease of handling and process standardization. These bags are transported to the processing area for further treatment. Accurate weighing at this stage is critical for maintaining consistency across batches and for cost tracking.

Within the processing phase, the tea leaves undergo several crucial steps. First, leaves are spread across pans and troughs for withering, which reduces moisture content and prepares the leaves for rolling and oxidation. The withering process, which occurs at controlled temperatures, influences flavor development and leaf integrity. Post-withering, the leaves are cooled to stabilize biochemical processes. Subsequently, they are removed from pans, reweighed, and placed onto specialized trays for rolling, which begins the formation of the characteristic tea leaf curl and influences flavor extraction during brewing.

The rolling process is vital, as it also initiates oxidation—an enzymatic reaction essential for developing the tea’s flavor profile. The leaves are subjected to two drying phases: the first drying occurs immediately after rolling to lock in flavors and prevent excessive oxidation, while the second drying, after oxidation, reduces residual moisture to safe storage levels. During these phases, careful temperature and humidity controls are maintained to ensure consistency and prevent spoilage.

Following drying, the tea leaves are cooled and inspected visually for quality issues, with substandard or broken leaves discarded to uphold product quality. The oxidized leaves are then moved into an oxidizing area where enzymatic reactions continue to develop flavor and aroma. Precise control over oxidation time is necessary, as it greatly influences the final taste and strength of the tea. The final drying stages solidify flavors and reduce moisture content to levels suitable for packaging.

Packaging involves weighing the dried, oxidized leaves before they enter the sorting process—a vital step where small, misshapen, or discolored leaves are discarded by machine inspection, ensuring only premium leaves proceed. The leaves are then packaged into paper tea bags, sealed, and wrapped into paper packets to maintain freshness. These sealed bags are grouped into larger cardboard packs of 20 units, which are sealed and prepared for shipment. The completed packs are then sorted and placed into shipping boxes, which are sealed and wrapped for transport.

This process flow highlights the complexity and precision required in tea production, emphasizing quality control, waste reduction, and sustainability. Incorporating recent innovations such as data-driven process optimization, biodegradable packaging, and energy-efficient drying techniques further aligns this workflow with environmentally sustainable goals while maintaining product excellence. Through continuous evaluation and lean principles, tea producers can reduce waste, conserve resources, and meet both consumer expectations and environmental standards successfully.
