Loading bay of cold store, part of slaughtering block and bridge to administration block
jointed in special cement to resist at- tack by blood and fats. The walls throughout the slaughterhouse are finished with glazed tiles so that they can be readily cleaned.
Windows are protected from direct sunlight by projecting vertical and horizontal fins and in the majority of working areas are not normally open- ed. Ventilation is provided by a sys- tem of louvred aluminium air inlet units close to the floor and extract ducts at ceiling level. Specific points such as tripe washers, scalding tanks, chute entries and eviscerating points are provided with specially located hoods.
The ventilation system provides 20 to 60 air changes per hour depending on conditions. It is designed so that the ventilation of each area can be controlled independently.
The roof of the slaughterhouse has lantern windows over the cattle dress- ing and pig slaughter and dressing areas. Storage tanks for a further 80,000 gallons of fresh water form part of the roof structure.
The upper mezzanine accommo- dates the cattle bleeding trough and de- horning point and is on the same level as the stunning pens on the bridge

from the lairage. Two specially de- signed hydraulically adjustable stun- ning pens are installed together with one rotary casting pen for ritual slaugh- ter purposes.
The lower mezzanine contains the dead animal butchery and the cattle stomach handling department. Two small refrigerated rooms are available on this floor for by-product materials and for specimens required for veterin- ary purposes.
An extensive by-products plant is situated on the ground floor, together with the isolation lairage and slaughter- house.
The slaughterhouse is supplied with a salt water downfeed from the lairage tanks, high pressure fresh water, hot tanks, high pressure fresh water, hot water by calorifier and steam, in ad- dition to the usual water services. These services together with the elec- trical services ductwork and drainage are all supported from the ceiling so as not to obstruct the working areas.
Refrigeration block
The refrigeration block is of three principal storeys. Reinforced concrete flat slab construction was selected for the main portion of this block in order to eliminate beams at ceiling level
where possible and also due to the relatively high floor loadings. Again provision is made for all tracking, services, etc. to be supported from above.
The ground floor accommodates the meat despatch bank, the refrigera- tion plant room, a fully equipped engineers workshop, certain toilet faci- lities, offices and the retail shop where edible blood and other materials are sold.
Two cool rooms are provided for beef with space for pigs or offals on the first floor. The remainder of the space on this floor is not cooled but is equipped with hydraulic rail droppers and power saws for quartering beef. The quartered beef can be transferred to a low level rail system and carried to the despatch bank via powered de- scenders.
On the second floor there are two cool rooms for pigs. Above this floor there is a void space immediately under the main roof slab. This is to give a measure of isolation to the cold rooms from sun heat on the roof and is used to accommodate the services to the offices at roof level on this block.
As part of the roof structure there is the insulated refrigeration plant 'A'
