This article briefly describes a case of application of monitoring and control of ethanol fermentation installed in the distillery plant of Tereos TTD, a. s., in Dobrovice, Czech Republic. The system developed to a large extent by the company ProjectSoft HK, a. s., was realized for fermentation processes both for raw juice and for various thick sugar juices (e. g. black syrup). Two flow charts briefly illustrate and the text describes the principle of ethanol production and the system of monitoring and control of the fermentation process. For such a big volume of treated raw material there would be no chance to reach the required production parameters without an optimal process control. © 2017, VUC Praha, a.s.. All rights reserved.

The paper is divided into two chapters. The first chapter briefly describes the technology of boiling massecuites with seed. The second chapter is devoted to a detailed description of control of massecuites boiling in a periodic pan, including the pan scheme with circles of measurement and control and a sequential control diagram. © 2016, Listy Cukrovarnicke a Reparske.

While sugar cane still remains the world's no. 1 crop for sugar production, its use for this purpose has been stagnating. Sugar beet, on the other hand, continues to show both qualitative and quantitative growth potential. Last year's world sugar production exceeded 181 million tonnes, and sugar consumption amounted to 175.8 million tonnes, i.e. an increase of 3.5 million tonnes compared to the previous year. Since the Sugar Common Market Organisation reform, the European Union has been showing an annual deficit of 3-4 million tonnes of sugar, handled through importations from third countries. These take place on the basis of reduced-duty tenders, duty-free importations, or industrial (non-food) sugar importations. This situation will change radically as of 30th September, 2017, when the quota regime is scheduled to expire, and the sugar market as a whole will be liberalised. Even though the Czech Republic is highly competitive, it must work hard to get prepared for the new liberal environment. As to bioethanol, 90 % of all production capacity is located in North, Central, and South America. In the Czech Republic, 1.3 million hectolitres of bioethanol were manufactured in 2013, together with 400-450 thousand hectolitres of food-grade alcohol.


The cumulative reduction of the EU sugar quota production was found as an impact of the reform of COM in sugar namely by almost one fourth. The position of the EU as one of the former significant world sugar exporter changed to the position of one of the biggest world importer due to the reform process. A quantity of 505 thousand tons of sugar produced in the Czech Republic prior to its access to the EU was reduced to the current quantity of 373 thousand tons produced in seven factories owned by five sugar companies. It is a matter of fact that the Czech sugar producers came through the reform process and the total sugar production in the Czech Republic achieved in the year 2010/2011 a quantity of 433 thousand tons which is a clear signal of the Czech sugar producers' capability to produce not the sugar quota only but the other quantities either for industrial purposes or for the export under the EU licenses as well. Continuing reduction of the sugar stocks in the EU (from 2,2 mio. tons in the year 2007/08 down to the expected quantity of 0,4 mio. tons at the end of the year 2010/2011) followed by a not sufficient and/or appropriate EC's steps lead in the tight situation on the EU sugar market. Current high sugar price at the world sugar markets is the other significant phenomenon whereas the price of white refined sugar at London's LIFFE exceeded the level of 800 US dollars per metric ton. Within the alcohol industry is the Czech Republic ranked among countries where the alcohol for the food industry is produced traditionally and followed by the dynamically developed sector of bioethanol production. A compromise changes in the Czech legislative laid to the raise of the mandatory blending of the bio-component with the classic fossil fuels for the Czech producers (m-v p from 3,5 % up to 4,1 %), which resulted in the new possibilities for growing an additional quantity of sugar beets for nonfood use. The EU 2020 strategy within the frame of the renewable sources of energy anticipates an achievement of the level 10% of the respective share of biofuels. The Czech sugar as well as the alcohol industry successfully managed to the process of registration of chemical substances within the REACH system under the active support provided by the CMSA and UEP CR.


Three production plants of Tereos TTD Company - sugar refineries in Dobrovice and České Meziříčí and distillery in Chrudim - are commemorating their anniversaries. Dobrovice Sugar refinery is the oldest and biggest running factory in the Czech Republic, the plant in České Meziříčí is the second biggest. Tereos TTD is also the biggest producer of ethanol; in addition to the distillery in Chrudim it operates the industrial distillery in Dobrovice.

The 2014/2015 campaign was mainly characterised by excellent beet growth conditions, extraordinarily long campaigns, and an oversupply of sugar associated with a dramatic downswing in prices. The world sugar inventory amounted to 76.7 million tonnes, thereof 3.5 million in Europe. Both figures are the highest ever. This situation made sugar prices fall by up to 40%. Despite the price drop, sugar beet remains a competitive crop in the Czech Republic, and is grown at a very good European level; over the last 25 years, yields have gone up by100%. Despite this, the post-2017 period will require further cost-reduction and efficiency-improvement efforts from both growers and processors. © 2015, Listy Cukrovarnicke a Reparske.

While sugar cane still remains the world's no. 1 crop for sugar production, its use for this purpose has been stagnating. Sugar beet, on the other hand, continues to show both qualitative and quantitative growth potential. Last year's world sugar production was in excess of 172 million metric tons; its consumption amounted to 169 million metric tons. Sugar consumption is up by about 2 %, i.e., by 3 million metric tons. Since the Sugar Common Market Organization reform, the EU has been showing an annual deficit of 3-4 million mt. The Commission deals with this by importing sugar from third countries. Importation is done on the basis of reduced-duty tenders, duty-free imports, and industrial sugar imports. The last campaign was exceptional in the Czech Republic; 565,000 mt of sugar were produced, thereof 372,000 mt of quota sugar and 193,000 mt of out-of-quota sugar. The quantity of beet processed for sugar production amounted to 3.9 million metric tons, at an average yield of 78.56 mt.ha-1, and 17.32 % average sugar content. As for bioethanol production, 90 % of all production capacities are to be found in North, Central, and South America. In the Czech Republic, 120 million litres of bioethanol were produced in 2010, compared to 90 million litres in consumption.
