Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of yogurt production, in particular to a yogurt fermentation device. Background Art
[0002] Yogurt is a dairy product fermented by lactic acid bacteria, usually made from milk or other animal milk, with a sweet and sour taste. Its production process usually includes the following steps:
[0003] Raw material selection and pretreatment: Select milk or animal milk that meets the quality requirements, filter, remove impurities and homogenize it, so that the subsequent fermentation process can proceed smoothly. Ingredients and homogenization: According to production needs, add appropriate amounts of sugar, additives and other ingredients to the raw milk, and homogenize it to make the various ingredients evenly mixed in the milk. Pasteurization: The raw milk is sterilized at high temperature for a short time to kill harmful bacteria and microorganisms in it, while retaining beneficial bacteria such as lactic acid bacteria. Cooling and inoculation: The sterilized raw milk is quickly cooled to a suitable temperature, and an appropriate amount of lactic acid bacteria starter is added to ferment it. Fermentation: Under appropriate temperature and environment, lactic acid bacteria will ferment in the raw milk, produce lactic acid and other metabolites, and gradually sour the emulsion. This process usually takes a certain amount of time to allow the lactic acid bacteria to fully ferment. Post-processing and packaging: After fermentation is completed, the emulsion is post-processed, such as heating, stirring, degassing, adding stabilizers, etc., to improve the taste and texture. Finally, it is packaged for consumers to eat or further processing.
[0004] However, when the prior art is actually used, during the fermentation process of raw milk using a fermentation device, a common fermentation device uses a fixed container to hold the raw milk, and uses a stirring paddle to mix and stir the raw milk inside the fixed container, so as to achieve the purpose of mixed fermentation of the raw milk and the lactic acid bacteria starter. However, when the stirring paddle is used to mix and stir the raw milk inside the fixed container, since the container is fixed, the raw milk is easily adhered to the inner wall of the container under the centrifugal force of the rotation of the stirring paddle, resulting in incomplete mixing of the raw milk and the lactic acid bacteria starter, thereby affecting the fermentation effect of the yogurt.
