Abstract

The invention relates to the feed additive technology, in particular to a polyethylene glycol coated potassium iodide and a preparation method thereof. In the invention, potassium iodide content is 85-95% by mass ratio and polyethylene glycol content is 5-15%. The preparation method thereof includes: firstly polyethylene glycol is melted in a water bath, then the melted polyethylene glycol is dissolved into absolute ethyl alcohol, then the solution of polyethylene glycol and absolute ethyl alcohol is sprayed into potassium iodide while the potassium iodide is fully stirred, and evaporation is carried out in an alcohol (ethyl alcohol) recovery tower, thus obtaining polyethylene glycol coated potassium iodide. The invention improves the stability of feed product and especially can protect other nutrient components from being influenced by potassium iodide.

Description

technical field [0001] The invention relates to feed additive technology, in particular to polyethylene glycol-coated potassium iodide and a preparation method thereof. technical background [0002] Potassium iodide is colorless or white cubic crystal, odorless, with strong bitter and salty taste. Potassium iodide has photosensitivity, and it is easy to release iodine in the air, which is yellow, unstable, and easily soluble in water. Adding potassium iodide to feed can meet the iodine demand of livestock and poultry, promote growth and development, improve feed utilization, and inhibit iodine deficiency. [0003] At present, the main way of adding in feed is to directly add potassium iodide (KI), which mainly has two shortcomings: [0004] 1. Potassium iodide itself has poor stability. During the feed preparation process, it is easily oxidized by oxygen in the air or other oxides in the feed, resulting in the loss of iodine content. [0005] 2. Affect the stability of vit...
