Abstract
The invention provides liquid nitrogen cryogenic granulating equipment. The equipment comprises a sealed cavity; liquid spraying equipment arranged on the top part of the sealed cavity; a liquid nitrogen tank, which comprises a first end part and a second end part, wherein the first end part is arranged below the liquid spraying equipment, and the inclination angle theta of the bottom plate of the liquid nitrogen tank is 1 degree to 30 degree; a big-hole screen, which is arranged below the liquid nitrogen tank and is used to sieve the particles from the second end part of the liquid nitrogen tank; a small-hole screen, which is arranged under the big-hole screen and is used to sieve the particles sieved by the big-hole screen; and a liquid nitrogen storage tank which is arranged under the liquid nitrogen tank. The improved liquid nitrogen cryogenic granulating equipment is used to produce multi-lactobacillus fermenting agent , has the advantages of stable product quality of different batches, convenience in use, and simple preparation technology, and the obtained fermenting agent particle has the advantages of uniform particle size and good appearance.
Description
Technical field [0001] The invention belongs to the field of food industry, and particularly relates to an improved liquid nitrogen cryogenic granulation equipment. Background technique [0002] For the research of yogurt production, from the initial use of natural mixed strains to prepare yogurt and other dairy products, to the selection of excellent fermentation strains to prepare pure strain liquid starters, and then to the high-efficiency freeze-drying that is easy to preserve and transport. The emergence of direct-investment starter marks the three eras of yogurt starter research. Many countries in Europe and the United States have begun to conduct research on starter in the early 20th century, and so far have achieved world-renowned achievements in the field of starter. Concentrated starter has achieved professional and commercial production and has been successfully applied to fermented milk. The production of products and the development of health-care lactic acid bacter...
