Embodiment Construction

[0016] The principles and features of the present invention are described below in conjunction with specific examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0017] The present invention is verified by following experiments:

[0018] 225L oak barrels were used, 216 were used for broken barrel sampling, 18 were used for continuous sampling, plus 10% spare samples, a total of about 260. In the event of abnormalities or data doubts during the detection process, start sample preparation. Aged in the pilot plant, the planned aging time is 36 months.

[0019] During the aging period, the oak barrels were subjected to microwave treatment once a month, and the oak samples and rum samples were taken the day before the microwave treatment. The processing frequency is 50-30000MHz, the processing power intensity is 1-60kW, and the duration of each time is about 1-600 seconds. The final parameters will be o...

Abstract

The invention relates to a method for treating a rum-aging oak barrel in microwaves. The method comprises the following steps: (1), after an oak barrel ages rum for one month, performing a first microwave treatment on the rum-aging oak barrel by using microwave with the frequency of 50-30,000 MHz and the power of 1-12 kW, and during later five months, performing once microwave treatment to the rum-aging oak barrel by using the microwave with the frequency of 50-30,000 MHz and the power of 1-12 kW in every month; (2), during 6-18 months when the oak barrel ages the rum, performing once microwave treatment on the rum-aging oak barrel by using the microwave with the frequency of 50-30,000 MHz and the power of 12-24 kW in every month; (3), after the oak barrel ages the rum for 18 months, performing once microwave treatment to the rum-aging oak barrel by using the microwave with the frequency of 50-30,000 MHz and the power of 24-60 kW in every month. According to the method for treating the rum-aging oak barrel in the microwaves, micropores in the inner wall of the oak barrel are abundant, the blockage during aging is prevented, and the purposes of improving the rum aging quality, accelerating the rum aging and prolonging the service life of the oak barrel are finally achieved.

Description

technical field [0001] The invention relates to the field of microwaves, in particular to a method for treating aged rum oak barrels with microwaves. Background technique [0002] In the process of aging rum in oak barrels, after 6 months of aging, most of the micropores on the inner wall of the oak barrels are blocked, the wood penetration rate is reduced, and the oxidation rate of alcohols, aldehydes, acids and esters is slow, which affects the aging effect. The aging cycle of brewing rum is extended. [0003] The aging period for making rum is generally 2 years (the time is more than 4 times that of wine). After the oak barrel is used for a period, it cannot be aged again for making rum. The price of oak barrels is relatively high, and the market price of a 225L standard barrel is between 4000-6000 yuan, accounting for more than 65% of the production cost of rum brewing. This poses a huge challenge to the supply of oak raw materials, and also increases the production co...
