Title: Improvements in or relating to monocalcium phosphate
IPC: C05B1/04
Filed: 1936-02-24
Abstract: Irregularly shaped, round cornered crystalline particles of monocalcium phosphate suitable for incorporation in leavening agents are prepared by reacting calcium oxide or hydroxide with strong phosphoric acid of 45--55 DEG  B<\>ae., agitating the mixture until it forms a damp, friable mass having a water content of say 5--12 per cent and a temperature of about 70--120 DEG  C., mechanically disintegrating the mass, separating the fine particles while maintaining an atmosphere of hot nearly saturated moist air, and drying the fine particles to produce a product having a low free moisture content, say below 0,5 per cent. Substantially all of the particles pass through a 100 mesh screen and by weight are greater than 20 microns in diameter.  The acid and lime are mixed in mixer 1 and the moist hot product is passed into a revolving cage disintegrator 2.  Thence the material is taken via elevator 3 and conveyer 4 to a mechanical air separator 5.  The material falls through pipe 8 onto a rotating distributer 9, Fig. 2, and fine particles are carried upwardly by a current of air circulated by fans 11, 12.  Large particles falling to the bottom of inner housing 13 are returned by line 6 to the cage mill 2.  Water vapour enters the mill 2 and air separator 5 by pipes 21 and 10 respectively to maintain the humidity at 85 per cent or higher.  The fine particles falling in the outer housing of the separator are discharged through line 15 into a rotary drier 7, and are dried by a counter current of air at 200--300 DEG  C. Monocalcium phosphate collecting in dust box 17 and dust collector 18 is returned to the drier.  The cage mill, conveying equipment and air separator are heat insulated. Comparisons are made in respect of the particle size, specific gravity, acidity, hygroscopicity and caking tendency of the present product and monocalcium phosphate obtained by dry-milling and by spray freezing.  <PICT:0472815/III/1> <PICT:0472815/III/2> Reference is made to a baking acid containing 75 per cent sodium acid pyrophosphate and 25 per cent monocalcium phosphate.ALSO:A baking acid comprises a mixture of 75 per cent sodium acid pyrophosphate and 25 per cent monocalcium phosphate, the latter being in the form of irregularly shaped, round-cornered crystalline particles, substantially all of which pass through a 100 mesh screen and by weight are greater than 20 microns in diameter.
