Sustained-release fish and shrimp oxygenating agent and preparation method thereof

Abstract

The invention discloses a sustained-release fish and shrimp oxygenating agent, and solves the problems of non-thorough disintegration, non-uniform gas production speed and non-uniform gas production amount of fish and shrimp oxygenating agents in prior arts. The sustained-release fish and shrimp oxygenating agent is prepared from the components of, by mass, 5-10% of vermiculite powder, 10-15% of microcrystalline cellulose, 2-5% of low-substitution hydroxypropyl cellulose, 2-5% of lactose, and balance of calcium peroxide. The sustained-release fish and shrimp oxygenating agent provided by the invention is scientific and reasonable, and has the advantages of good safety, synergistic components, thorough disintegration, slow gas production speed, uniform gas production amount, and long gas production time. The oxygenating agent has a good application prospect. The invention also discloses a preparation method of the sustained-release fish and shrimp oxygenating agent. According to the invention, the components are weighed according to the ratio, and are directly tableted. The process steps are simple; production cost is low; and investment is low. The method is suitable for large-scale industrialized productions.

Description

technical field [0001] The invention relates to an oxygen enhancer, in particular to a slow-release fish and shrimp oxygen enhancer and a preparation method thereof. Background technique [0002] At present, in the process of transportation or sales of live fish and shrimp, due to the high density of fish and shrimp in fish boxes or fish barrels, it is easy to cause death due to lack of oxygen. Therefore, in order to improve the survival rate of fish and shrimp in the process of transportation or sales, it is necessary to Fish and shrimp are oxygenated. [0003] At present, the most commonly used way of increasing oxygen is to directly increase oxygen into the water body by connecting the sand head of the oxygen increasing pump. Using the oxygen increasing pump to increase oxygen, the energy consumption is high, the bubbles generated will rise and burst rapidly in the water, the oxygen increasing effect is poor, and It will cause the water body to roll from bottom to top,...
