§ 584. Holding Method.
(a) Where holding method of pasteurization is used and the product heated above 161 degrees F., the holding time may be reduced by one minute for each degree of temperature above 145 degrees F., provided the product so treated will successfully pass the phosphatase test for pasteurization as prescribed in the current edition of Standard Methods for the Examination of Dairy Products.
(b) Each holder vat must be equipped and operated with a satisfactory means of keeping the atmosphere in the vat above the milk or milk products at a temperature of t least 5 degrees F. higher than the required pasteurization temperature of the product during the heating and holding period. If steam is admitted into the vat, the steam line must be provided with a trap properly designed to avoid the discharge of water into the product. An approved sanitary type air temperature indicating thermometer must be installed on each vat. The air temperature thermometer must have a scale range of 130 degrees F. to 210 degrees F. Temperature ranges above or below are permissible. It must be accurate within 1 degree F. plus or minus, through the specified scale range; the smallest scale division must not be more than 2 degrees F. and not more than 16 degrees per inch of scale.
(c) Recording thermometer charts made for products pasteurized by the holding method must show the end point of the holding period by some distinguishing mark which must be made before any of the product is removed from the vat. A notation must be placed on the recording chart showing the temperature of the air space as indicated by the air space thermometer for each vat of product pasteurized.
(d) Flush-type outlet valves are required on pasteurizing vats.
(e) Installations made after the effective date of this provision shall comply with the following: If the interior lining of the vat is flared at the valve opening, then the diameter at the large end of the flare shall be at least equal to the depth of the flare, plus the diameter of the opening. The distance from the small end of the flare to the valve shutoff point or the distance from the interior lining to valve shutoff point if no flare is used shall not exceed the diameter of the opening.
(f) Indicating thermometers shall be accurate within 0.5 degrees F., plus or minus, within the pasteurization temperature range, and shall have a scale range of 130 degrees to 212 degrees F., extension either side permissive, protected against damage at 220 degrees F. The smallest scale division shall not be more than 1 degree F. between 130 degrees and 150 degrees F. The magnification of the mercury column shall be to apparent width of not less than one-sixteenth inch ( 1/16). Spuds of indicating thermometers shall be at the level of the spud of the recording thermometer.
(g) Recording thermometers and charts not exempt by subsection (e) of Section 583 of the Administrative Code must comply with the following specifications:
Temperature Accuracy. Within 1 degree F., plus or minus, between 142 degrees and 145 degrees.
Time Accuracy. The recorded elapsed time as indicated by the chart rotation must not exceed the time elapsed as indicated by a correct timepiece over a period of at last 30 minutes.
The smallest temperature scale division must not be greater than one degree between 140 degrees and 145 degrees F.
The width of the scale division between 142 degrees and 145 degrees F. must not be less than one-sixteenth of an inch.
The radial lines that indicate the time must not be closer than one-fourth inch between 142 degrees and 145 degrees F. and represent not more than 10 minutes.
