摘要:

Results are presented which show that the water formed during the combustion of hydrocarbon fuel is significant in relation to the evaporation potential of the fuel when used in a direct gas‐fired drier. As a result, the outlet air humidity of direct‐fired driers is higher than that of indirect‐fired plant operating at the same outlet and inlet air temperatures. The powder moisture increases with increasing humidity at constant temperature. To compensate for this increase in moisture content, either the drier must be run at a lower inlet temperature throughout, or the outlet temperature of the drier must be increased. However, with heat sensitive materials such as milk a serious loss in powder solubility can occur if the latter action is chosen. These results suggest that the difference in overall efficiency of direct and indirect forms of heating in spray driers is less than has previously been as

摘要:

The paper describes the work done by the Aberdeen and District Milk Marketing Board on the production of dried‐milk‐based products such as calf milk replacers, to give a higher return than dried skimmed milk. Proposals for alternatives to buttermaking are also gi

摘要:

This investigation has used a Yellow Springs Instrument Co., Inc. (YSI) Model 23A glucose analyser to measure the glucose produced by the hydrolysis of the lactose solution with β‐galactosidase. The analyser was also used to measure initial and final glucose values before and after hydrolysis of a low lactose high glucose/galactose product such as a lactose hydrolysed whey syrup. The accuracy and reproducibility of the glucose analyser is excellent provided that (i) operation and calibration techniques are consistent, (ii) the analyser is injected with samples which have ben suitably diluted to the optimum glucose range of 100–300 mg dl‐1, and (iii) the instrument and its ‘syringepet’ are both maintained. The error in measuring the small increase in glucose from the small quantity of lactose present is thereby great
