Journal of electricity . on the principle of a can which revolves inice, but consist of a stationary cylinder, silver lined,surrounded by an air-tight space in which is coiled,close against the side of the cylinder, rectangular- August 15, 1920] JOURNAL OF ELECTRICITY 175 shaped copper pipes through which the brine is circu-lated sixteen times around the cyhnder at a tempera-ture of 0° F. while the mixture within the cylinderis agitated by two sets of paddles which rotate withtwo different motions similar to the paddles in thecommon home freezer. The flavoring is added to this mixture as it isdrawn into the freezers—a specific amount beingadded to each freezer batch. The cream is not frozen hard in these freezers,but is diawn off at a pasty consistency into the cansor molds, and passed immediately into the hardeningroom where it hardens and ages. This hardeningroom is kept at a required temperature of 10° ormore below zero, F. by means of a current of airblown against ammonia expansion pipes, and in here. One of the ammonia compressors where the ammonia, expanding, extractsheat from the brine used as a refrigerant. the cans and molds are left for four hours beforethey are ready to be sent out for distribution. Ices are prepared in the mixers on the third floorand drawn from there direct into the freezers; alsofrozen puddings. The punches are prepared, as arule, by hand. Special Equipment Containers are thoroughly cleansed and steril-ized of course before being filled, special machinerybeing used for this purpose. Centrifugal brushes,through which streams of boiling hot water aresprayed, scour the cans, after which the cans areplaced in sterilizing machines where they remain inboiling water for one minute; they are then placed ona rack where they dry almost immediately, on theirway to the freezing room. The company operates specially built trucks fordistributing the product in and around Fresno, therebeing twenty of these vehicles in all, part of whichare Walke
