The scale is thus softened, and can then be detached by the scrapers. (2) The juice should enter the first vessel at a high temperature, by avoiding excessive cooling between chemical treatment and evaporation. (3) To maintain a high vacuum in the last vessel the air-pump must be sufficiently powerful, and the condensing- water sufficient in quantity, and at a suitable temperature. In most factories, the hot water escaping from the condenser is pumped to a cooling-tower outside the factory, whe...nce it returns to the condenser. It is desirable to ascertain the temperature of the water entering the condenser from time to time. TYPES OF EVAPORATORS USED 259 (4) Air and incondensable gases (from the steam used, or from the boiling juice) must not be allowed to accumulate in the steam-drum of each vessel, but are drawn off by means of small tubes, and pass to the condenser. These gas- and air-outlets are called " ammonia pipes " because boiling beet- juice evolves a small quantity of ammonia.
