Administrative Rules of Montana › Department 32 - LIVESTOCK › Chapter 32.9 - GENERAL LICENSING AND PROVISIONS › Subchapter 32.9.4 - Manufactured Dairy Products Plants - General Requirements › Rule 32.9.417 - SEPARATORS AND PASTEURIZING EQUIPMENT

Current through Register Vol. 13, July 5, 2024
(1) All
				product contact surfaces of separators must be free from rust and pits and
				insofar as practicable be of stainless steel or other equally non-corrosive
				metals.
(2) Coil or dome-type batch
				pasteurizers must be stainless steel lined and if the coil is not stainless
				steel or other equally non-corrosive metal, it must be properly tinned over the
				entire surface. Sanitary seal assemblies at the shaft ends of the coil vats
				must be of the removable type, except that existing equipment not provided with
				this type gland will be acceptable if the packing glands are maintained and
				operated without adverse effects. New or replacement units must be provided
				with removable packing glands. Dome-type pasteurizer agitators must be
				stainless steel except that any non-metallic parts shall meet 3-a sanitary
				standards for plastic or rubber and rubber-like materials, as applicable. Each
				pasteurizer used for heating product at 165° F. or lower for 30 minutes or
				less must be equipped with space-heating equipment and the necessary
				thermometers to insure a temperature at least 5° F. above that required for
				pasteurization of the product. There must be adequate means of controlling the
				temperature of the heating medium. Batch pasteurizers must have temperature
				indicating and recording devices.
(3) When pasteurization is intended or
				required, an approved timing pump or device recorder-controller, automatic flow
				diversion valve and holding tube or its equivalent, if not a part of the
				existing equipment, must be installed on all high temperature short-time (HTST)
				equipment used for pasteurization, to assure complete pasteurization. The
				entire facility must meet the 3-a accepted practices for the sanitary
				construction, installation, testing and operation of HTST pasteurizers. After
				the HTST unit has been tested according to the 3-a accepted practices, the
				timing pump or device and the recorder controller must be sealed at the correct
				setting to assure pasteurization. Sealing of the HTST unit must be performed by
				the control authority having jurisdiction. When direct steam pasteurizers are
				used, the steam, prior to entering the product, must be conducted through a
				steam strainer and a steam purifier equipped with a steam trap and only steam
				meeting the requirements for culinary steam may be used.
(4) Surface coolers must be equipped with
				hinged or removable covers for the protection of the product. The edges of the
				fins must be so designed as to divert condensate on non-product contact
				surfaces away from product contact surfaces. All gaskets or swivel connections
				must be leak-proof.
(5) Plate-type
				heat exchangers must meet the 3-a sanitary standards for construction and
				installation. All gaskets must be tight and kept in good operating order.
				Plates must be opened for inspection by the operator at sufficiently frequent
				intervals to determine if the equipment is clean and in satisfactory condition.
				A cleaning regimen must be posted to insure proper cleaning procedures between
				inspection periods.
(6)
				Internal-return-tubular heat exchangers should meet the 3-a sanitary standards
				for construction and installation.
