Problems solved by technology

The process line is long, the scenting time is long, the production cycle is long, the labor intensity is high, the labor cost is high, the aroma of jasmine is lost seriously, and the aroma utilization rate is low
When scenting high-grade tea, because jasmine flowers and high-grade tea are squeezed together during the scenting process, it is easy to deform the high-grade tea, which increases the difficulty of scenting high-grade tea
Due to the cost, the traditional scented tea made with fresh jasmine is almost medium and low-grade scented tea, which leads to the misinterpretation that scented tea is medium and low-grade tea.

Abstract

The invention relates to a method for directly scenting scented tea by using a fragrance adsorbent. The fragrance adsorbent after saturation adsorption is mixed with a desorption solvent so as to be directly added to a scenting device, and basic tea in the scenting device is prepared into scented tea. The method comprises the following manufacturing steps of: firstly, refiring the basic tea to be dried, adjusting the optimum moisture content of the basic tea to be scented, and then putting into a saucer of the scenting device; mixing 5% to 50% fragrance adsorbent by weight percent of the basic tea and 0.5 to 3 times the desorption solvent by weight percent of the fragrance adsorbent so as to be sealed, placing the mixture into a cooler so as to be cooled to -5 DEG C to -30 DEG C, then putting the mixture into the scenting device, and sealing the scenting device; or firstly, cooling 5% to 50% fragrance adsorbent by weight percent of the basic tea at the temperature of -5 DEG C to -30 DEG C, quickly putting the fragrance adsorbent into a sealing tank at the temperature of 50 DEG C to 100 DEG C so as to be desorbed for 5 to 30 minutes, circularly sending the fragrance adsorbent into the sealed scenting device by an exhaust fan through a pipeline, and providing proper scenting conditions such as temperature and humidity so as to scent the basic tea into the scented tea.

Description

technical field [0001] The invention relates to a method for directly scenting scented tea with a floral scent adsorbent, in particular to a method for directly scenting scented tea in a tea scenting device by utilizing the scented scent adsorbent saturated and adsorbed with floral scent and after detachment through special treatment. Background technique [0002] Hengxian County, Nanning City, Guangxi is a famous hometown of jasmine. The planting area and output of jasmine account for about 80% of the country's total, with an annual output of nearly 100,000 tons of fresh jasmine. The jasmine industry in Heng County is mainly based on scenting tea with fresh flowers, and there are a few manufacturers producing jasmine extract and absolute oil. The industrial structure is relatively simple. [0003] The traditional process of scenting tea with fresh jasmine is generally two scentings and one scenting four scentings, while middle and high-grade scented tea needs 5 to 10 scenti...
