Description

A spiral permeabilization fermentation device

technical field

The utility model belongs to the field of fermentation equipment, in particular to a spiral permeabilization fermentation device.

Background technique

With the comprehensive and rapid development of the horse industry in Xilinhot, the "horse capital of China", the 2,000-year-old horse milk is facing a transformation and upgrading from tradition to modernity. However, the fermentation of sour milk is different from that of milk. It is an aerobic fermentation, that is, it needs to be continuously filled with oxygen and continuously emit carbon dioxide during the fermentation process.

In the past, yogurt was fermented and filled with oxygen, which was mainly achieved by opening the container to contact with the air, which was not hygienic, and at the same time, the cleanliness of the air could not be guaranteed. The removal of carbon dioxide was mainly achieved by the artificial wooden stirrer moving up and down, and the stirring could not be precisely controlled. It is difficult to ensure the taste, quality and efficacy of kumis milk due to the time, frequency and intensity.

At present, domestic sour milk fermentation mainly relies on traditional wooden stirrers to manually stir yogurt up and down, stirring 2-3 times a day, 800-1000 times each time, opening the cylinder mouth to contact oxygen, in order to meet the needs of fermentation For parameters such as temperature, put the fermentation container 20-30 cm underground. When the temperature rises, cool it with cold water. In winter, add insulation materials around the container to meet the fermentation conditions. This kind of traditional fermentation cannot guarantee the time, frequency and intensity of stirring required for product fermentation, and the temperature and environment required for fermentation cannot meet the process requirements.

In foreign countries, the fermentation of sour kumiss mostly adopts automatic circular motion stirring. Although this stirring method can mix materials, it only moves on the same plane and cannot move up and down. The carbon dioxide produced by fermentation cannot be fully discharged, and the required oxygen cannot be timely. In addition, in terms of strain fermentation, the fermentation conditions of different fermentation strains at different stages cannot be satisfied.
