Raw Juice Flow Control, Screening, Heating and Liming
ثبت نشده
چکیده
In preparation for defecation clarification of raw or mixed juice, the juice is screened, heated, limed and flashed, while the flowrate of juice to the clarification process is carefully controlled. Despite the potential for enhancement or optimisation in each.of these pre-treatment areas, the past 50 years of South African Sugar Technologists' Association (SAST~) proceedings offer only six papers dealing specifically with aspects of pre-treatment. This paper reviews some of their findings in the light of current practice, discusses pres~nt installations in the South African sugar industry and considers probable future directions.

The Effects of Chemical Purification on the Color of Thin and Thick Juices in Sugar Beet Factories
Background and Objectives: Recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. Factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...

The use of controlled heating to separate centrif ugally the white and green protein fractions from freshly expressed alfalfa juice has been investi gated. Heating in a batch-type operation, with a slug flow heat exchanger, or by direct steam injec tion has been conducted over a range of tempera tures (30-64°), times (10 sec-20 min), and pH values (5.5-8.6). Results indicate a superiority o...
متن کاملOzonation as an effective way to stabilize new kinds of fermentation media used in biotechnological production of liquid fuel additives
BACKGROUND Intermediates from processing sugar beets are considered an attractive feedstock for ethanol fermentation due to their high fermentable sugar content. In particular, medium prepared from raw sugar beet juice seems to be suitable for use in fermentation processes, but it is microbiologically unstable and requires sterilization. RESULTS This study investigates the effect of ozone tre...
