Nitrogen-filling preservation method of silo-stored tea seeds

Abstract

The invention relates to the technical field of tea seed preservation, and discloses a nitrogen-filling preservation method of silo-stored tea seeds. The method comprises the following steps: S1, treating tea seeds, namely performing air-drying on tea seeds to be warehoused, controlling the moisture of the tea seeds to be 5-7.5 percent, and then screening out impurities of the tea seeds; S2, performing evacuation in the silo, namely extracting air in a preservation silo through a vacuum pump, and keeping the vacuum degree of the preservation silo to be 0.09 Mpa; S3, controlling the environment in the silo, namely starting a nitrogen making unit and a cooling unit; and S4, monitoring the environment in the silo, namely monitoring parameters such as temperature, humidity and nitrogen concentration in the preservation silo every day, and supplementing nitrogen in time when the parameters are lower than the parameters. According to the nitrogen-filling preservation method of silo-stored tea seeds, the tea seeds are subjected to moisture air-drying, impurity removal and other treatments, so that the freshness, dryness and purity of the tea seeds entering the preservation silo are ensured, the tea seeds can be in a dormant state while the influence of impurities on the tea seeds is reduced, the consumption of respiration is reduced, and the quality of the tea seeds cannot be reduced due to long-time storage.

Description

technical field [0001] The invention relates to the technical field of tea seed preservation, in particular to a method for storing tea seeds in a silo and filling them with nitrogen for freshness preservation. Background technique [0002] Tea seeds are the seeds of camellia trees, which can be used to cultivate new camellia trees or to extract oil. Because tea seed oil has antioxidant capacity, can lower blood pressure, blood fat and inhibit arteriosclerosis, the demand for tea seed oil is increasing year by year Big, so that more and more people joined the camellia planting industry. [0003] Since tea seeds are seasonal crops, a large amount of tea seeds need to be purchased in season, so tea seeds that are too late to be processed need to be stored, and these stored tea seeds are prone to mildew, which affects product quality and oil yield. Therefore we propose a kind of silo store tea seed and fill the method for keeping fresh with nitrogen to solve the problem. Con...
