Tea drying equipment
Tea drying equipment is a general term for tea drying equipment and frying equipment. Used for drying and dehydrating tea leaves, fixing their appearance and color, enhancing their aroma and removing green air, meeting the requirements for drinking, packaging, and storage.
The heat transfer media used for drying and frying are different, with the former being flowing air or heat rays, and the latter being metal thermal conductors. The drying equipment mainly consists of a leaf holding device, a heating device, and a ventilation and air permeability device.
The main factors determining the quality and efficiency of tea drying are drying area, media temperature, and ventilation and air permeability. The heating device includes a hot blast stove, a steam heat exchanger, and an electric heating conversion device. Drying equipment includes drying cages, drying ovens, and dryers. The frying equipment includes a hand frying pan and a frying dryer.
tea roasting basket
Drying basket is a tea drying equipment. Used for initial tea processing and drying. Originating from the Tang Dynasty in China. A drying rack and charcoal basin made of bamboo or iron wire.
When baking tea, first lay a layer of white gauze on the drying rack, place the tea leaves that have been killed, kneaded, or stir fried on the gauze, place a charcoal basin under the rack, and use charcoal fire as a heat source for baking. The baking temperature can be controlled by adjusting the amount of charcoal and the thickness of the furnace ash coating. During the baking process, each part of the tea should be swapped several times to achieve simultaneous drying. Due to the small leaf area and low yield of the drying basket, it is only suitable for drying a small amount of famous tea
Drying stove
Tea drying equipment. Used for initial tea processing and drying. Composed of a stove pit and several tea trays shaped like steamers stacked together.
During homework, the tea leaves are evenly spread on the tea tray, and charcoal fire is placed in the stove pit. The drying temperature and water evaporation rate are controlled by controlling the amount and combustion rate of charcoal fire. Low production, high charcoal consumption, and complicated operation have been largely replaced by dryers.
Tea dryer is a general term for fully automatic and semi-automatic tea drying equipment. Used for initial tea processing, drying, refining, and reheating. Composed of a host and a hot air generating device.
According to the structure and working principle, there are types such as hundred page type, chain plate type, mesh belt type, cylindrical type, vibration type, boiling type, etc; Using electricity as the heat source, it can be divided into far-infrared dryers, high-frequency dryers, microwave dryers, etc; According to the flow mode of hot air, there are positive pressure, negative pressure, etc.
During homework, the tea leaves are evenly spread on the mesh plate, and the hot air generating device supplies hot air to the leaf layers on the mesh plate. The tea leaves are continuously moved and flipped by the mesh plate, ensuring that the drying medium and tea leaves maintain uniform and sufficient contact, completing the drying process.
