Задание 1. Прочитайте и переведите текст:

The laboratory

The well laid out laboratory is equipped for maintaining quality control standards on samples taken at all stages of process operations. A Multiscan infra-red analyser is used to give rapid readouts of butter fat content, protein, lactose and

solids. The bacteriological testing area has a laminar flow cabinet with automatic planting apparatus and laser beam equipment (Don Whitley Scientific) for colony counting.

In the main laboratory, detergent concentration for CIP circuits is controlled by a Detomat С automatic unit. This is a new system devised by Lever Industrial, and Marshfield has the first installation in the world.

The Detomat С is based on the M range, but combined with the latest microprocessor technology, is said to have greater flexibility, and increased reliability. It automatically controls 9 separate detergent application points which can all require different concentration levels of both caustic and acid cleaning solution.

Channels 1 – 6 are for the soak rinse tanks on bottle and crate washers; channels 7 and 8 are for caustic and acid pasteuriser cleaning solutions, and channel 9 controls the caustic cleaning solution for all tanks, pipelines and bottle fillers.

The VDU monitor displays, on demand:

A. Solution concentration levels on all channels, set concentration levels, high alarm set points, and channel state (high, dosing, normal, low and initial detergent in use).

B. Time delays in seconds for dosing, high and low.

C. Temperature of each detergent solution together with minimum temperature setting for dosing interlock.
