Liquid nitrogen cryogenic granulation equipment

Abstract

The invention discloses liquid nitrogen cryogenic granulation equipment which structurally comprises a bottom frame, a magnetic turning plate liquid level meter, granulation equipment, a controller, an air heater and a vacuum pump and has the following beneficial effects that the novel liquid nitrogen cryogenic granulation and efficient freeze-drying equipment scheme is provided, the cost is low, the current requirements of local probiotic enterprises are met, and the application prospect is wide. Not only are the dosage form problem and the equipment problem of local yogurt starter products solved, but also the freeze-drying efficiency of strains is improved, and the activity stability is improved; generally, the equipment scheme of the patent is low in manufacturing cost and simple to operate, and the problem of equipment cost of freeze-drying after local probiotics liquid nitrogen cryogenic granulation is solved; the risk that particles are broken during discharging of the screw is avoided, small particles are discharged, and the problem of continuous discharging is solved; heating is carried out by aeration in the vacuumizing process, preheating is carried out to 30-60 DEG C according to different processes, and the particle temperature and the drying efficiency are effectively improved in cooperation with adjustment of a freeze-drying curve.

Description

technical field [0001] The invention belongs to the technical field of special protective agent scheme and equipment for liquid nitrogen cryogenic granulation, and particularly relates to liquid nitrogen cryogenic granulation equipment. Background technique [0002] In recent years, the local probiotic industry has developed rapidly, but this is mainly due to the rapid development of the local probiotic market, while the industrialization of local probiotic strains has lagged behind. The serious imbalance between the two has led to foreign probiotic strains dominating the domestic market. , especially the local yogurt starter strains have basically not yet achieved large-scale industrialization. [0003] The industrialization of local probiotic strains is basically divided into three aspects, namely strain development, core production technology and process research and development, application and product development. At present, great progress has been made in the two link...

AI Technical Summary

Problems solved by technology

[0011] In order to overcome the shortcomings of the existing technology, a liquid nitrogen cryogenic granulation equipment is proposed to solve the core problem of the large-scale industrial production of the current local yogurt starter strains, which is the instability of fermentation activity, especially the instability between batches; The yogurt starter granulation production equipment currently used abroad is expensive, and the effect is unbearable for domestic enterprises
