Gain in washing from hot weight 13.48% = 231 lbs.
Weight to chill vat 1,860 lbs.
Chilled twenty hours, weight 2,009 lbs.
Gain from washed weight 8.01% = 149 lbs.
Gain in chilling from hot weight 22.57% = 370 lbs.
Weight chilled to oil house 2,009 lbs.
Handled in the usual way, gives following:
| Yield in oleo stock, | 1,070 lbs. = | { | 65.28% from hot weight |
| 57.53% from washed weight | |||
| 53.45% from chilled weight |
Butcher Fats.
—Kidney fat yields the largest percentage of stock of any fat in the animal. The fat in this particular part seems to be richer in oil and in the general handling of same it rarely goes into the water to absorb additional weight, as it is generally purchased from the retail butcher after the carcass has been cut up. This in itself is a large branch of the business, in many places melters making a practice of collecting from the butchers their bones, tallow and fat. The following test will give an idea of the yield of the different products brought from a butcher’s shop, when used in an oleo factory or tank room. The prices quoted are those that were paid at the time tests were made. The percentages, however, are accurate.
