Problems solved by technology

[0004] At present, the processing methods of this kind of instant tea include the extraction of raw tea and the filtration, concentration and drying of the extract. Among them, the extraction includes organic solvent extraction and water extraction. Organic solvent extraction needs to recover the solvent, and there are solvent residues in the product. However, the composition of the extract is different from that of water infusion, so it is difficult to truly meet the taste requirements of tea drinkers.

Embodiment 1

[0020] Example 1: Select 100kg of Pu'er tea as the raw tea, add water 8 times the weight of the raw tea, complete the extraction and boiling in a dynamic closed dynamic cycle, concentrate under reduced pressure for 5 hours, and reflux at the same time to extract the aged volatile oil of Pu'er tea. When the specific gravity of Pu'er tea concentrate is 1.1g / ml, filter, and the filtrate is transported to the top of the 40m high tower, the liquid pressure is 2MPa, the pressure is released suddenly and the atomization is in contact with the air with an inlet temperature of 130°C and a pressure of 0.5MPa. Heating for 5 seconds, when the temperature of the hot air drops to 98°C and the pressure is 0.4MPa, a hollow Puer tea granule with a diameter of 0.05-0.4mm is obtained, and the content of water and aged volatile oil in the hollow Puer tea granule is 2%-8%. , tea polyphenol content is 14%-25%, total ash content is 10%-16%, caffeine content is 7%-13%, solubility g / 100g≥95, tea polysa...

Embodiment 2

[0022] Embodiment 2 Take 100kg green tea as the raw tea, add water 16 times the weight of the raw tea, complete the lifting and boiling in a dynamic closed tower with dynamic stirring and circulation, and concentrate under reduced pressure for 8 hours. During the reflux process, the aged green tea aroma volatile oil is extracted simultaneously. When the specific gravity of the green tea concentrate is 1.5g / ml, filter, transport the filtrate to the top of a 30m high tower, pressurize the filtrate to 3MPa, let the filtrate suddenly release the pressure from the discharge hole and atomize, and the temperature of the other inlet is 160°C , contact with air with a pressure of 0.3MPa, and heat for 1 second. When the temperature of the hot air drops to 96°C and the pressure is 0.2MPa, hollow green tea particles with a diameter of 0.05-0.4mm are obtained. Hollow green tea granules contain 6% moisture and aged volatile oil, 14% tea polyphenols, 16% total ash, 13% caffeine, 16% tea polys...

Embodiment 3

[0024] Embodiment 3 Take 100kg of black tea and add 10 times of water, in the dynamic closed tower, the dynamic agitation and circulation are completed to extract and boil, and concentrate under reduced pressure for 7 hours. When the specific gravity of the black tea concentrate is 1.3g / ml, filter, the filtrate is transported to the top of the 20m high tower, pressurize the filtrate to 4MPa, let the filtrate discharge from the discharge hole, the filtrate suddenly releases the pressure and atomizes with another inlet temperature Contact with air at 150°C and a pressure of 0.4MPa, and heat for 4 seconds. When the temperature of the hot air drops to 97°C and the pressure is 0.3MPa, hollow black tea particles with a diameter of 0.05-0.4mm are obtained. Hollow black tea granules contain 8% water and aged volatile oil, tea polyphenols 14%, total ash 10%, caffeine 7%, solubility g / 100g ≥ 95, tea polysaccharide 10%, crude protein At 30%, the total amount of free amino acids is 2%, th...

Abstract

The invention discloses a solid-state instant tea granule and a preparation method thereof. The tea granule is a hollow granule with the diameter of 0.05-0.4mm. The instant tea granule comprises green tea, black tea, Oolong tea, Pu'er tea or the mixture thereof. The preparation method comprises the following processing steps: taking raw tea and adding 8-16 times water, completing the extractive boiling via dynamic sealing and dynamic circulation, decompressing and concentrating for 5-8 hours and simultaneously extracting raw tea perfume volatile oil via backflow. When the proportion of raw tea concentrated solution is 1.1-1.5g / ml, the concentrated solution is filtered, filtrate is delivered to the top of a high tower of 20m-40m, the liquid pressure is 2-4MPa, pressure release is suddenly carried out for atomization so as to make the filtrate contacted with air with the temperature of 130-160 DEG C and the pressure of 0.3-0.5MPa, and after 1-5 seconds of heating, when the temperature of hot air is reduced to 96-98 DEG C and the pressure is 0.2-0.4MPa, the instant hollow tea granule or the instant hollow granule with tea flavor is obtained. The method has the characteristics that the water extraction and concentration of tea and the collection of tea perfume volatile oil are completed dynamically and circularly in an enclosed system simultaneously, so energy and water consumption are saved, and the production efficiency is increased by three times.

Description

technical field [0001] The invention relates to a solid instant tea granule and a manufacturing method thereof. It belongs to the technical field of tea beverage processing. Background technique [0002] my country has a history of tea production for thousands of years, and today has formed a variety of teas such as green tea, black tea, oolong tea, scented tea, white tea, yellow tea, dark tea, pressed tea, teabags, beverage tea, instant tea, etc. A variety of products to meet the needs of people's hygiene. Instant tea is a new product developed in the 1950s, which brings great convenience to people's drinking. However, after checking the relevant information, the production of instant tea in the world at present all uses tea powder to extract tea with water for many times, and then concentrates and dries the low-concentration tea. Although there is also freeze-drying after the tea is concentrated, the energy consumption is large and the cost is high. In order to reduce t...
