Abstract

Spray drying process and spray drying installation are of the type in which a powder is produced by injecting a spray of liq. contg. CO2 into the top of a spray drying tower into which a current of ht air is blown. The CO2 is diffused into the liq. as tiny gas bubbles each with dia. of about 0.5 to 1.0mm at a distance of 1 cm. from the diffuser. In order to ensure that all CO2 is completely dissolved before the liq. reaches the spray head, the proportion of CO2 to liw. is restricted and the distance between diffuser and spray head is increased as necessary. The liq. pref. enters the tower via. a centrifugal atomising turbine and the diffuser is located at a low point in a riser piper bringing liq. up to the turbine. This produces a local increase in liq. press. just downstream of the diffuser and assistor in dissolving the gas. Spray-drying liq. to produce edible powders such as milk prods., partic. skimmed milk, as well as concentrate of tomato and other fruit and vegetables, instant coffee and tea powders. Compared with spray drying a liq. produces a powder of increased solubility and which is less hydroscopic. Process heating requirements are reduced and output can be increased by =12%.
