To solve or reduce the caking problem of ammonium bicarbonate,sulfonates and other substances were added in the production of ammonium bicarbonate to promote nucleation,improve the crystalline form of ammonium bicarbonate,and improve the separation of ammonium bicarbonate crystals and mother liquor.However,these additional additives will affect the subsequent industrial usage,and restrict the applying field.Ammonium bicarbonate that meets food additive requirements was obtained using combined technologies,such as pulping and washing,centrifugal separation,air drying,mother liquor deoiling and additive removal etc..The technology has been successfully applied in industrial production to solve the shortage of high purity ammonium bicarbonate and improve the economic benefit of ammonium bicarbonate production enterprises.
Key words: ammonium bicarbonate; food additives; anti-caking agent; sulfonate
