No u veiles de I'in dustrie Purdue University Conferences, July 17-20 1990 Three conferences and two short courses will take place at Purdue University in July 1990. The International Compressor Engineering Conference is the 10th in a series of biennial conferences at Purdue which began in 1972. Papers are solicited related to current research and engineering practice on positive displacement compressors for refrigerants, air and other gases. The USNC/IIR Purdue Refrigeration Conference is the third in a series of refrigeration conferences sponsored by Purdue and the IIR. The Ray W. Herrick Laboratories and the US National Committee for the International Institute of Refrigeration are the principle sponsors for this 1990 'Progress in the Design and Construction of Refrigeration Systems Conference'. Papers are solicited on all aspects of refrigeration machinery technology and applications. The third conferenceis the ASHRAE~ Purdue CFC Conference, which is a follow-up to the ASHRAE CFC NIST Conference (September 27 28 1989). Papers are solicited from all engineering and scientific personnel doing work related to the CFC problem. The two short courses are 'Signal Processing' (Instructors Patricia Davies, Peter Sherman and Stuart Bolton) and 'USNC/IIR Short Course on CFC Alternatives' (Leader Hans O. Spauschus). Further information can be obtained from Phyllis Hurst, Conference Secretary, Ray W. Herrick Laboratories, Purdue University, West Lafayette, IN 47906, USA.
Full range of defrosting systems from AFOS A comprehensive range of bulk tempering and thawing equipment for meat, fish, fruit and vegetable products is now available from AFOS Ltd of Hull.

Six sizes of trolley-loaded systems, a small batch thawing cabinet and a thawing inspection table comprise the range, which is supplemented by purpose designed stainless-steel racks and trolleys and an automatic bactericidal spray system for the air circulation ducts. All the systems operate in similar fashion and are designed to eliminate waste associated with incorrectly thawed products. Each is divided into upper and lower chambers. Fan, heat exchangers and water sprays are housed in the upper chamber while the lower chamber houses the air circulation plenum chambers and the thawing compartments. The frozen product is loaded into these compartments on trolleys and air is circulated over the product in a laminar flow pattern at controlled temperatures and humidities. Maintenance of high humidity levels prevents surface dehydration whilst flow direction is reversed at 30 min intervals to ensure even thawing. If the unit is to be used for tempering purposes refrigeration coils can be provided in the chambers to provide maintained tow temperatures at the end of the cycle. All units are available in tunnel or batch-loaded configurations dependent on the process requirements. Tunnel type arrangements allow the hygienic separation of frozen product and wet process area. Control systems are available ranging from simple semi-automatic units to microprocessor controlled programmable units. Since it is important to control product core and surface temperatures very accurately for process and hygiene reasons, the unit can be provided with temperature probes, indicators and alarms. In addition all units with a standard process alarm system and chart recorders can be fitted as an option to record product and air temperatures and air humidities. Standard units are available in batch capacities from 250 kg for the T250 thawing cabinet up to 9000 kg for the 6/9000 systems (all capacities based on 100 mm frozen block). The
Int. J. Refrig. 1990 Vol 13 March
inspection table has cabinet capacity of 75 kg. Construction throughout the range is in stainless-steel with D section neoprene seals giving a watertight seal between the door and the main frame. Steam, hot water or electrical heating systems can be specified. AFOS Ltd, Manor Estate, Anlaby, Hull, HU10 6RL, UK.
Hygienic unit from Edenaire Edenaire Ltd is now able to supply a specially designed range of hygienic air handling units. These units have been developed, based upon the West German Din 1946 sheet 4 (Ventilation in Hospitals), by Euroclima of ltaly. With air w)lumes from 0.355 to 4.93 m3/s at 2.5 m/s face velocity the main design consideration, in addition to the maintenance of strict climatic conditions, has been the micro-bacteriological impurities in the air. Therefore the hygienic units have large fully opening doors allowing complete removal of internal components leaving a completely smooth interior for washing and disinfecting. An external gutter permits the controlled collection and retrieval of the cleaning fluid. Doors are fitted with special rubber sealing gaskets and joints are sealed with an anti-bacteriological sealant. All units have standard 50 mm insulated skirl panels and are of modular construction using standard panel sizes. This permits considerable flexibility in unit composition, configuration and materials, supported by a choice of optional accessories. Unit sections can be manufactured with stainless-steel aluminium or galvanized interior walls and with stainless-steel aluminium o1" precoated plastic galvanized sheet. Coils similarly are available in a range of materials and are all tested tinder water to 31 bar air pressure~ Edenaire Ltd, Four Elms Road, Edenbridge, Kent TN8 68D, UK.
