Description

technical field [0001] The present invention relates to mechanical equipment, more specifically to a kind of preparation device of 2-hydroxyl-4 methylthio-calcium butyrate. Background technique [0002] The trade name of 2-hydroxy-4-methylthio-butyrate calcium is also called hydroxymethionine calcium. As an amino acid feed additive, it is an excellent source of amino acids. It can be effectively converted into methionine in animals for protein synthesis. Improve animal growth rate and poultry egg production rate, and at the same time, it is a high-quality organic calcium, which provides high-quality calcium source for animal growth and development, and has good economic benefits. The preparation method of the 2-hydroxy-4-methylthio-calcium butyrate has the advantages of short process flow, low equipment investment, low production cost, etc., and the finished product is a solid powder, which is easy to use, has a wide range of applications, and does not need a special feeding...

AI Technical Summary

Problems solved by technology

The preparation of calcium 2-hydroxy-4-methylthio-butyrate by the current mixing dryer has the following defects: calcium oxide or calcium hydroxide in solid state and 2-hydroxy-4-methylthio-butyric acid in liquid state It is difficult to mix the solutions at the beginning, and it is also difficult to react, but once the two react, the reaction will be very violent and the reaction speed is very fast. Thereby cause speed of reaction, pressure and temperature to be difficult to control, and after temperature is greater than 130 degrees, product 2-hydroxyl-4-methylthio-calcium butyrate can decompose or coke, on the other hand, a part of material (as calcium oxide or Calcium hydroxide or intermediate products, etc.) are easily wrapped into large groups or large pieces, and cannot fully participate in the reaction, resulting in a relatively insufficient amount of reaction raw materials, insufficient reaction, more intermediate products, and low product purity, thereby affecting product yield. and quality

Moreover, after the material is wrapped into a large ball or block, the moisture inside is difficult to evaporate during drying, which affects the overall drying of the material and greatly prolongs the drying time of the material, resulting in a relatively long production time and affecting the output.
