Problems solved by technology

Among them, the wet process is to add solid raw materials to the phosphoric acid solution prepared by the wet process to generate calcium hydrogen phosphate dissolved in water. After vacuum concentration, cooling and crystallization, calcium hydrogen phosphate crystals are precipitated, and then dried, crushed, and sieved to obtain the product , this method has the disadvantages of long process flow, large phosphorus loss, high energy consumption, large investment, small production capacity, and high cost.

Abstract

The present invention discloses feed-grade calcium hydrogen phosphate. The feed-grade calcium hydrogen phosphate comprises the following raw materials in parts by weight: 30-50 parts of lime milk, 20-30 parts of phosphate ore, 10-20 parts of hydrochloric acid, 40-60 parts of bone meal, 1-3 parts of tea residues, 2-6 parts of fruit residues and 1-5 parts of a nutrient additive. The feed has characteristics of being high in phosphorus content, high in water-soluble content, etc., can accelerate growth and development of livestock and poultry, shortens fattening period, rapidly increases weight,can improve breeding rate and survival rate of the livestock and poultry, at the same time can enhance ability of the livestock and poultry to resist diseases and cold, and has preventive and therapeutic effects on cartilage diseases, white diarrhea, and paralysis diseased of the livestock and poultry.

Description

technical field [0001] The invention relates to feed grade calcium hydrogen phosphate and a preparation method thereof, belonging to the technical field of animal feed preparation. Background technique [0002] Feed grade calcium hydrogen phosphate is an excellent high-efficiency phosphate feed additive with high phosphorus content and high water solubility. It is widely used as a feed additive for aquaculture animals and livestock and poultry animals. Due to the high water-soluble phosphorus content of calcium dihydrogen phosphate, which accounts for more than 90wt% of total phosphorus, it is beneficial to the absorption of calcium and phosphorus by aquatic animals. The digestion and absorption rate is above 90%, and the excretion is small, which is beneficial to environmental protection. It is widely used at home and abroad. [0003] At present, wet process and dry process are commonly used at home and abroad to produce feed grade calcium hydrogen phosphate. Among them, ...
