Patent GB-2023790-A (GB)
Title: Air slide freezer system
IPC: A23L3/36
Filed: 1978-09-21
Abstract: A method and system for preparing comestibles for frozen storage in which pressurized freezing air is utilized in conjunction with a substantially flat conveyance surface both to air in or contribute to the conveyance of the packages or containers as well as to effectuate the rapid freezing of the comestibles therein during the course of such conveyance through the system. In the preferred embodiment, the elongated conveyance deck (100) is of space saving substantially helical form with successive descending turns underlying one another and with the space surrounded by the turns forming part of a plenum chamber (110) into which pressurized freezing air is blown for admission into a laterally opened plenum duct (120) underlying the deck throughout its length. Such elongated plenum duct is tapered traversely beneath the deck for uniform distribution of pressurized freezing air to the discharge apertures (100a) in the deck by means of a transversely inclined duct-forming panel (114) cooperating with the deck. On its upper side the panel forms the plenum duct and on its lower side the panel cooperates with a surrounding enclosure (104) common to the helical turns to the conveyance deck to form a collecting chamber from which air is withdrawn by the combined freezing (130) and pressurizing (132) means for recirculation continuingly as the containers or packages descend by increments progressively down the helical path of the deck. A partition (116) with variable damper means (150) separates the central plenum chamber and the surrounding collecting chamber and provides a variable bypass to regulate or vary the flow of air through such discharge apertures and maintain constant airflow through refrigerated evaporator coil (130) so as to maintain efficient heat exchange operation thereof. With the comestibles (C) packaged in the usual manner so as to afford air space within the packages for expansion of the comestibles upon freezing, the method of combined conveyance and freezing by use of the pressurized air flow greatly accelerates the freezing process and effects conveyance of the comestibles, appropriately retarded to maintain relative high-velocity flow of air sweeping the packages, without necessity for mechanical conveyance devices. <IMAGE>

Title: Flow fluctuation damper
IPC: F16L55/052
Filed: 1979-09-11
Abstract: In order to reduce pulsations in a pipeline 1, a tube 2 is closed at its top end and filled with air in the space 3 between the liquid level 4 and the top end of the tube. The liquid level 4 is controlled by a probe 5, and when the liquid level reaches the probe an air supply is switched on to supply incoming air via an inlet line 7 which is helically coiled around the outside of the pipe 2 and within a steam jacket 10. The incoming air is thus sterilized before being released at the free open end of the line 7 within the space 3. In this way, a pre-set level of the liquid level 4 can be maintained and the sterility of the air within the space 3 is also maintained. To prevent possible thermal damage to the liquid flowing in the line 1, a considerable space is left between the bottom of the jacket 10 and the level 4. <IMAGE>
