Description

Production equipment and method of fermented liquid goat cheese Technical Field The invention relates to the technical field of dairy product processing, in particular to production equipment and method of fermented liquid goat cheese. Background The liquid goat milk is a dairy product which is rich in nutrition and easy to digest and is prepared by taking fresh goat milk as a raw material through sterilization, fermentation, maturation and other processes. The key step of the production process is a fermentation process, namely, the goat milk inoculated with the starter is placed in a fermentation tank, beneficial microorganisms such as lactobacillus and the like are grown and propagated at a constant temperature, and acid and aroma are produced, so that a liquid product with unique flavor is finally formed. However, in the industrial production process of liquid sheep cheese, complex physical and biochemical reactions in a fermentation tank lead to a series of long-term pending technical problems, which seriously affect the quality and production efficiency of the product. In the fermentation process, carbon dioxide gas generated by lactobacillus metabolism continuously escapes, and in addition, the protein (especially whey protein) in the goat milk easily forms a stable bubble layer on the liquid level layer due to fluid disturbance caused by mechanical stirring or circulating pumping. In the prior art, a mode of adding a chemical defoaming agent is adopted for defoaming, but the pure natural quality of the goat cheese is affected by the residual chemical defoaming agent, the problem of bubble formation cannot be fundamentally solved, the goat milk contains rich protein and fat, and during the fermentation process, the casein gradually undergoes colloid coagulation along with the decrease of the pH value, so that fine curd particles are formed. These curd particles are slightly denser than whey and tend to settle to the bottom of the can in a resting state, forming a dense deposit. The fermentation of liquid sheep cheese is a dynamic process, and as curd is formed, the viscosity of the system is gradually increased, and the fluidity of materials is reduced. At this time, it is difficult to achieve uniform mixing over the full tank range with conventional overhead stirring or circulating pumping means. The fermentation process is extremely sensitive to temperature, and particularly for products with high flavor requirements such as goat milk cheese, fermentation abnormality can be caused by temperature fluctuation exceeding a threshold value. However, the conventional fermenter generally has the problems of radial temperature gradient, such as rapid temperature change of materials near the wall of the fermenter due to jacket heating or cooling, delayed temperature response of materials in the middle of the fermenter, formation of a cold center, reduced thermal conductivity after curd formation, and further expansion of temperature difference. This temperature difference has the undesirable consequence of causing it.
