Embodiment Construction

[0024] As shown in the figure, a kind of sterilization process for the production of neomycin sulfate utilizes plate heat exchanger 1, preheating tank 2 and spray drying tower 3 to carry out the sterilization work of neomycin sulfate production, comprising the following steps:

[0025] 1) The neomycin sulfate solution is passed into the plate heat exchanger 1 from the feed liquid inlet 4, and at the same time, the steam tail gas generated in the production process is passed into the steam tail gas inlet 5, and the neomycin sulfate solution is heated to 78~90℃;

[0026] 2) Pass the heated neomycin sulfate solution into the preheating tank 2 through the plate heat exchanger 1, and keep warm in the preheating tank 2 for 3min~5min.

[0027] 3) After the specified holding time is reached, the neomycin sulfate solution is passed into the spray drying tower 3 for subsequent production and processing.

[0028] In a preferred scheme, the incubation time of the neomycin sulfate solutio...

Abstract

The invention relates to a sterilization process and device for neomycin sulfate production. A plate heat exchanger, a preheating tank and a spray drying tower are used for sterilization in neomycin sulfate production. The method comprises the following steps of: (1) introducing neomycin sulfate solution to the plate heat exchanger from a feed liquid inlet, also introducing steam tail gas generated in the production process from a steam tail gas inlet, and heating the neomycin sulfate solution to 78-90 DEG C by utilizing the steam tail gas; (2) introducing the heated neomycin sulfate solution to the preheating tank from the plate heat exchanger and heating for 3-5min in the preheating tank; and (3) introducing the neomycin sulfate solution to the spray drying tower for subsequent production processing after the specified insulation time. By adopting the structure, the efficient sterilization of the neomycin sulfate raw powder is realized, the product quality meets the market requirement, and at the same time, the cost investment is greatly lowered, and the enterprise production benefit is improved.

Description

technical field [0001] The invention relates to the field of chemical production equipment, in particular to a sterilization system for the production of neomycin sulfate. Background technique [0002] In order to ensure that the microorganisms of neomycin sulfate products are qualified, the existing sterilization method is that the spray tower first adopts the pasteurization method of preheating in the preheating tank for 30 minutes at 62°C to disinfect the refined solution of neomycin sulfate entering the tower. The volume of the hot tank is nearly 1000L, and it takes 70 minutes for the feed liquid to enter and exit. Due to the long storage time of the feed liquid in the preheating tank, the light transmission of the refined liquid is greatly reduced. In order to ensure that the color of the raw powder meets the quality standard, it is necessary to increase the light transmission of the refined liquid by adding more carbon during the salt conversion process. At the same ti...
