Steam drying of beet pulp in Japan and latest development of the technology

In order to reduce the energy use it is useful to divide the different processes in the factory into energy “users” and energy “transformers”. The juice evaporator train is a “transformer”. When designed correctly all ingoing energy will leave the evaporator to be used elsewhere. Drum drying of pulp and the sugar house are “users”, as most energy supplied cannot be recovered. To save energy requires attention to the “users”, and the “transformers” shall be adapted to fit into the system, so they are only transformers. Examples of this are given. In doing so, it is possible to come down to approximately 140–150kWh supplied energy as fuel. This includes making sugar into white sugar, molasses with a purity of around 60%, and drying all the beet pulp. Energy saving offers reduced CO2 emission. Half of all the VOC (volatile organic compounds) leaving a sugar factory comes from the drum drying of pulp. Steam drying, however, produces no VOC and no dust emission to the atmosphere at all.

Steam Drying

Freshly pressed and dried sugar beet pulp was sampled from 2different factories located within a distance of 30km and on 4different dates. One factory was equipped with a steam dryer and the other with a drum dryer. A recognized in vitro technique was used to establish, how the drying process affected rumen fermentability of the pulp, since fibrous feeds (such as sugar beet pulp) rely on microbial fermentation in the rumen to be digestible to the cow. Steam dried pulp had a remarkable >60% higher fermentability compared to drum dried pulp during the first 12(–15)hours of fermentation, but there were no differences in fermentation pattern after 24hours of fermentation. The increased early fermentability must markedly increase the nutritional value for high-yielding dairy cows, which at feed intakes of 25kg dry matter or more, have retention times in the rumen for water soluble compounds (such as pectin) and small particles as low as 6.7–13.3hours. Future feeding trials are needed to establish exactly how much the feeding value is increased in steam dried sugar beet pulp.

Steam Drying

Three sugar beet pulp samples, which were dried by different methods (drum-dried, steam-dried, and shelf-dried), were prepared and hot water extractions (90 °C, 6 h) were performed to compare the pectic polysaccharide yield. The steam-dried pulp yielded 34.1 g of pectic polysaccharides per 100 g of dry matter. This represented about twice the yield of the other techniques, with a recovery of about 60% of the estimated amount contained in the raw material. The pectic polysaccharide obtained from the steam-dried pulp by hot water extraction and dialysis contained larger amount of arabinose (32.4 g/ 100 g solids) as constituent sugars than that of commercial beet pectin. The weight-average molecular mass was 175 kDa, which was lower than that of commercial beet pectin (538 kDa) and most of the extracted feruloyl group were bound to this polysaccharide. These characteristics were similar to those of pectic polysaccharides obtained previously by autoclave extraction from wet beet pulp. It was presumed that the pectic polysaccharides contained in sugar beet pulp were partially hydrolyzed and solubilized under pressurized and high temperature conditions (0.25–0.3 MPa, 150–180 °C) during steam drying, making them easier to extract. Using steam-dried pulp as a raw material, feruloylated arabinan-rich pectic polysaccharides can be efficiently obtained by hot water extraction under non-pressurized conditions without acid addition.

Steam Drying

The drying of pressed sugar beet pulp in a pressurised fluidised bed with superheated steam is widely used in the sugar industry and can be considered to be state of the art for energy-efficient drying concepts in combined plant systems. The process has been used on a large scale in the sugar industry for more than 20 years. In the past campaign, BMA subjected existing drying systems at various locations to a number of refinements. These systematic, process engineering modifications allow the driers to work more efficiently and reliably. Feeding pressed pulp into a fluidised-bed drier is a critical phase in the drying process and can lead to malfunctions. The ability to determine the fluidisation conditions in the first drier cells provides more detailed insights into the process so that critical situations can be detected at an early stage and therefore malfunctions can be avoided. Further investigations have shown that the height of the fluidised bed has a considerable effect on adequate product transport and on the degree to which the heat from the circulated steam is utilised and, consequently, on water evaporation.

Structural changes in the intestines of quais at fodder mycotoxicosis are described. The use of antitoxic feed additives in poultry led to a weakening of the action of xenobiotics, which was confirmed by an increase in the safety of poultry and increase in body weight of quails, a decrease in the clinical manifestations of intoxication, as well as in positive changes in the structure of the intestine of the poultry during histological examination.

And Control

Fluidised-bed steam dryers have been in use for industrial-scale drying of pressed beet pulp for more than 20 years. This highly energy-efficient process can be considered to be state of the art in the industry. Scientific laboratory and pilot-plant testing have provided the basis for a detailed description of the principles of fluidisation and drying in superheated water vapour. Advances in production data acquisition, in particular regarding the options for the real-time presentation and evaluation of high-resolution operating data (Industry 4.0), have opened up new potentials for optimisation of the drying process in fluidised-bed steam dryers. By analysing and interpreting sequences of events, or simultaneous events, it is now possible to analyse process behaviour in great depth. This allows malfunctions to be avoided by improved design or, assisted by suitable measuring and control systems, to be detected at an early stage. Failures can then be prevented altogether by initiating automated countermeasures. On the basis of more recent insights gained from the analysis of faults and disruptions using modern operating data acquisition, BMA’s fluidised-bed steam dryer (WVT) has been subjected to fundamental technological and technical improvements, so it now meets today’s demands for efficiency and reliability. Modifications include the product inlet, the distribution plate and several other parts, in addition to the known and patented PPS (Plug Protection System; EP 2457649 B1), and the patented rotary weir (EP 2146167 B1).
