Metamorphosis of Twin Screw Extruder-Based Granulation Technology: Applications Focusing on Its Impact on Conventional Granulation Technology

In order to be at pace with the market requirements of solid dosage forms and regulatory standards, a transformation towards systematic processing using continuous manufacturing (CM) and automated model-based control is being thought through for its fundamental advantages over conventional batch manufacturing. CM eliminates the key gaps through the integration of various processes while preserving quality attributes via the use of process analytical technology (PAT). The twin screw extruder (TSE) is one such equipment adopted by the pharmaceutical industry as a substitute for the traditional batch granulation process. Various types of granulation techniques using twin screw extrusion technology have been explored in the article. Furthermore, individual components of a TSE and their conjugation with PAT tools and the advancements and applications in the field of nutraceuticals and nanotechnology have also been discussed. Thus, the future of granulation lies on the shoulders of continuous TSE, where it can be coupled with computational mathematical studies to mitigate its complications.

CHEMICAL COMPOSITION AND NUTRITIONAL VALUE OF THE NEW CITRUS POMACE FEED ADDITIVE

The materials of the article present data on research on the chemical, mineral-vitamin composition and nutritional value of a new feed additive from citrus pomace. The article presents the results of research on the technological line of granulation of citrus waste, established the optimal composition for granulation of citrus feed additives: sunflower meal - 20%, molasses - 5% and 75% of citrus fruits.Their chemical composition was studied, the gross content of proteins, fats, assimilated carbohydrates, including simple sugars, was determined, and the efficiency of use in the diets of farm animals was determined. The positive influence of citrus waste granulation technology has been established, which allows to obtain high-quality granules. Chemical analysis of citrus granules showed that 100 g contains: protein - 6.15 g, fat - 0.99 g, carbohydrates - 21.8 g, of which simple sugars 14 g, the energy value of this feed additive - Kcal (kJ) - 120.7 (505.7).The possibility of preparation of feed additives in the form of granules is revealed, which allows to avoid selfsorting of components and overdose of microelements and to improve the consumption of feed ingredients. The ability to prepare feed additives in the form of granules avoids self-sorting of components and overdose of micronutrients and improve the consumption of feed ingredients. The results of zootechnical researches, structure and nutritional value of average daily rations with use of citrus pomace are resulted.It was found that the introduction into the diet of dairy cows feed additives from citrus pomace during stable lactation increases the average daily expectations by 1.8 kg or 15.5%, feed costs for milk production containing 4 fat were 0.97-0, 98 feed units. When using a feed additive from citrus pomace, the nutritional value of the diet is improved due to the ratio of sugar - protein (0.62: 1 vs. 0.8: 1.2).

Rice granules with improved solubility prepared via fluidised-bed granulation

The purpose of this study was to improve the processability of rice powder using fluidised-bed granulation technology. Bukkyungmi-rice granules were prepared by fluidised-bed granulation for 1 and 2 h using water, 5% lactose (w/v) and 5% dextrin (w/v) solutions as dispersants. The particle size of Bukkyungmi-rice granules increased from 574.83 to 728.07 μm. Granules were produced due to pore formation, and the produced particles could be dispersed easily without any entanglement. The water solubility of the produced rice granules is 1.91–6.74%, which reflects the improvement in their quality with increased treatment time. In particular, Bukkyungmi-rice granules processed in 5% dextrin showed excellent settleability. The enthalpy (ΔH) was found to be the highest for Bukkyungmi-rice granules processed in 5% dextrin for 2 h by differential scanning calorimetry. The results indicated that rice granules obtained by fluidised-bed granulation could be used in various types of rice-based foods.

Press granulators, technical features, influence of granulation on qualitative characteristics of feed

An important task for any farming enterprise producing animal products is to provide feed with high nutritional value for the animals. At the same time in addition to growing and preserving feed of their own production, farms purchase, including food processing products: brewing waste, beetroot pulp, brewer’s grains, etc. These wastes are usually delivered in liquid form and have a low nutritional value and shelf life, as well as a high specific cost of transportation. One of the solutions to this problem is the use of granulation technology. The main types of press granulators, their design features and operating principles, as well as the materials of scientific researches aimed at studying the properties of granulated feed have been described in the article. Thus, according to the materials studied, the use of press granulators in the process of processing food waste allows to achieve an increase in their nutritional value and shelf life of feed. Analysis of the use of granulated feed in the diet of animals has shown their better digestibility compared to feed presented in crumbled form, which contributed to an increase in productivity in animals. Thus, we can conclude that the use of press granulators in the process of feed preparation of various designs is a promising direction of production. At the same time, the choice of the granulator should be based on its technical features and performance. So, for a small agricultural enterprise, fl at-matrix granulators with a capacity of up to 1000 kg/h are suitable.

NEW DIRECTIONS FOR CREATING SLAG GRANULATION TECHNOLOGY COPPER PRODUCTION

New technological processes of pyrometallurgical depletion of slag solve issues of either intensification or wastelessness. To solve the problems of intensification, melt mixing is used mechanically or by gas. Top tuyere lances are used, as well as sparging with reducing gas in PV type furnaces. Acceptable results were obtained at pilot plants, but non-waste tasks were not solved.
