Description

Caproic acid bacterial liquid sampling device Technical Field The utility model relates to the field of caproic acid bacterial liquid sampling, in particular to a caproic acid bacterial liquid sampling device. Background The strong fragrance is taken as one of twelve major fragrance types of Chinese white spirit, and has strong cellar fragrance, sweet and clean fragrance, coordinated fragrance and the sensory characteristics of a fragrance purification plant, so that the Chinese white spirit has the greatest distribution and the greatest audience. The strong aromatic Chinese spirits are divided into Sichuan style strong aromatic Chinese spirits, jianghuai style strong aromatic Chinese spirits and northern strong aromatic Chinese spirits according to regions, and are divided into single grain strong aromatic Chinese spirits and multi grain strong aromatic Chinese spirits according to raw materials, and are divided into original pit method, pit method and Lao Wu Tong according to processes, so that it is known that the strong aromatic Chinese spirits have complicated process, unique charm of the process, but have the advantages that its main aromatic substance is ethyl caproate, and the ethyl caproate is the effective method for judging the quality of the strong aromatic Chinese spirits, so that most of strong aromatic Chinese spirits factories use "increasing the quantity of the raw spirits as the main work of their daily production, and in the work of increasing ethyl caproate, one important link is the preparation of caproic acid bacteria liquid, because caproic acid bacteria are anaerobic bacteria, can better monitor the fermentation process, sampling analysis of caproic acid bacteria liquid is indispensable, At present, caproic acid bacterial liquid is realized through deep stationary culture, and samples are taken in the culture process, and a triangular bottle is uniformly shaken and then taken, so that the purpose of uniform shaking is to be uniform up, down and up, and fermentation conditions can be reflected more truly, but the defect is that the uniform shaking process inevitably contacts with the air of the upper layer, and how to realize the sampling of the bacterial liquid of the upper, middle and lower layers under the condition of no shaking is the problem to be overcome in the patent.
