Description

Fresh-keeping packing plant of high activity fresh yeast Technical Field The utility model relates to the technical field of yeast preservation, in particular to a high-activity fresh yeast preservation packaging device. Background Fresh yeast is used as an active biological agent and has wide application in the fields of food fermentation, brewing and the like. At present, most of common fresh yeast fresh-keeping packaging modes in the market are simple sealed packaging, and although the fresh yeast fresh-keeping packaging modes can isolate external pollution to a certain extent, the control effect on humidity and oxygen is poor. Too high humidity can easily cause the yeast to grow bacteria, while too low humidity can dry and inactivate the yeast, and at the same time, the yeast needs a proper amount of oxygen for respiration in the storage process to maintain the activity, but the oxygen content and impurities in the outside air are difficult to accurately control. In addition, the fresh yeast is easy to precipitate in the storage process, so that the yeast is unevenly distributed, and the use effect of the fresh yeast is affected.
