The sugar beet campaign 2009/10 was, compared to the previous one, characterized by a lower sugar content. The yield significantly increased, and is comparable with values of quality growers of the neighboring states. The amount of sugar prescribed by the quota system was easily fulfilled and, as in other EU states, even a certain amount of surplus sugar was produced: in the Czech Republic, this was 29% of total sugar produced (for bioethanol, chemical use, etc.) The whole EU quota for the 2009/10 campaign was 13,121 kt and the surplus quota 4,347 kt, thus 33.1%. The average sugar content was 16.85% (18.70-15.99%). The average duration of a campaign in the Czech Republic was 93.4 days, and the total production of white sugar from beet was 431.8 kt. Seven sugar factories were operating in the Czech Republic during the past sugar campaign, the total standard capacity was 37,394 tons per day while one of the factories had surpassed 14,296 tons in a single day. The data confirm the fact that the Czech Republic with a 200 year tradition of sugar beet production is among the leading sugar producers in the European Union. The article briefly mentions investment events aimed at the improvement of ecology, technology and energetics that were realized in Czech sugar factories during the 2009/10 campaign. Source

The aim of C sugar operation in a sugar factory is a high quality C sugar for effective follow-up refining, minimizing sugar in molasses together with low energy consumption. On the other hand, biotechnology - ethanol fuel production - can change these targets: either sugar in molasses is increased for fermentation processing (higher sugar content) or C sugar operation is excluded from the sugar technology at all so that the refinery process can be simplified. To optimize the effect of cooling crystallization, a new static model was developed. The model involves balance equations for a horizontal crystallizer or for a part of vertical crystallizer of C-sugar operation and takes in account the balance of the sucrose ratio in liquid and solid phase. An addition of mixing media, such as syrup or water, into the crystallizer has been also considered. Molasses is applied in many food or non-food processes because of high content of nitrogenous compounds, carbohydrates and its sweet taste. Molasses is traditionally used in fermentation technologies to produce ethanol and for production of animal feed. The further potential applications are given. © 2012 Published by Elsevier Ltd.

The 2009/10 campaign was characterized by the good technological quality of the sugarbeets, although the sugar content varied markedly between the various regions because of considerable differences in weather conditions during the growing and processing periods. The regional average sugar contents ranged between 15.99% and 18.70% (overall average, 16.85%), below those of the previous campaign. The campaign lasted, on average, 93.4 days (maximum 114 days). Production came to 431, 800 t white sugar. The beet processing capacity of the seven sugar factories totalled 37, 450 t/d. The key technological performance indicators confirm the position of the Czech Republic as a producer of high-quality sugarbeets and sugar. Bioethanol production from sugar beet continued in the 2009/10 campaign for the second year. Last May saw the opening of a museum in Dobrovice, dedicated to the sugar industry, alcohol distillation, beet agriculture and the town Dobrovice itself. Source

The article describes the issues connected to organic beet processing and production of organic sugar (bio-sugar) and other organic products (organic molasses, organic pulp, organic sludge etc.) used in organic farming. In the Czech Republic, there is only a single sugar factory capable of processing organic farming products for sugar industry – Hrušovany nad Jevišovkou sugar factory that belongs to the group Moravskoslezské cukrovary, a. s., i. e., Agrana Group (Austria). Annual production of organic sugar is about 4,000–6,000 t. Other products necessary for organic farming are also produced (organic sludge – fertilization, organic pulp – fodder etc.). A number of tables show the results of analysis – conventional as well as organic sugar - regarding contaminating substances, granulometry etc. The amount of processed organic sugar beet from 2008 to 2013 can also be found there. © 2015, Listy Cukrovarnicke a Reparske.

Sugar beet campaign 2011/2012 in the Czech Republic was characterized by great quality of sugar beet which was achieved thanks to almost ideal weather conditions not only during the vegetative period of sugar beet but also during the processing campaign. The year 2011 was evaluated as dry (precipitation total was 83 % of long-time average). The average temperature difference on the area of the Czech republic was +0,8 °C which placed this year in the group of the so called "warm years". Total processed amout of sugar beet was 3.576 mil tonnes with the average tuber yield of 71.25 t.ha-1 and polarizing sugar yield of 12.57 t.ha-1. During processing of sugar beet which took 114.1 days, 564,440 tonnes of white sugar were made. As in the last four years, there were seven sugar factories belonging to five different companies. These seven sugar factories had a standard processing capacity of 39,914 t.d-1. Standard processing in one factory reached 15,285 t.d-1. Biosugar production amounted to 7,000 t. The given data prove that the Czech Republic with its 200 year tradition belongs among top sugar beet growers and processors in the EU. Apart from beet for sugar, there was also processed 740,000 t of beet for bioethanol in Tereos TTD company. The article lists the main investments of individual companies before the campaign of 2011.
