Abstract This work aimed to evaluate the effect of carrier agents containing maltodextrin and protein, represented by hydrolyzed collagen on the spray drying process of cocona (Solanum sessiliflorum Dunal), and on the properties of the resulting powders. We used pre-established proportions between the solids of cocona pulp and the carrier agents (P:CA), and among carrier agents themselves, maltodextrin and hydrolyzed collagen, (MD:HC). The process was carried out in a spray dryer at an inlet air temperature of 120 ºC. We prepared twelve feed solutions containing 20% of total solids, with P:CA ratios of 1:3, 1:4, 1:5 and 1:6, and MD:HC ratios of 0:100, 50:50, and 100:0. Solids recovery was obtained for the evaluation of the spray drying process. The cocona pulp powders were analyzed for moisture content, water activity, particle size distribution, mean particle diameter, chemical structure (FTIR) and color. For a P:CA of 1:6, for the sample formulated with hydrolyzed collagen only, solids recovery (96.2%) was much higher than that of the sample with maltodextrin only (39.2%). The chemical structure of cocona powders can be considered a sign of a good encapsulation process. The color of the cocona pulp powder was similar to that of the carrier agents. The formulation with highest content of hydrolyzed collagen improved the recovery of solids, guaranteed the cocona pulp encapsulation, and obtained fruit powders with bioactive properties.

Nowadays, coffee has become one of the most favorable commodities for beverages, flavoring as well as for cosmetic industries. In Indonesia, coffee becomes more popular, especially among youngsters. In this study, the spray drying process was evaluated, giving the potential of how simple spray dryer can help local farmers of Indonesia to produce their coffee powders. One small scale of spray dryer was constructed with the total dimensions of 2.85 x 0.64 for length x width, with a height of 2.32 m. The spray dryer was equipped with a digital thermo regulator, the pneumatic nozzle system, and 4 finned heaters with the power of 2700 watt for each. The spray drying constructed was revealed to be able to produce coffee powders with fine quality. The inlet temperature of the drying chamber, as well as the initial Brix content of feed solution, were proven to affect the physical properties of powder produced such as moisture content, product yield, and solubility. The final moisture content of powders was ranged from 3 - 7% db, with the high product yield of the drying process, which could reach up to 70%.

Hollow Structures

Polyacrylate microspheres with a hollow structure were prepared by a facile spray drying method. The effects of spray drying process parameters, including inlet temperature, atomizer rotational speed, and feed speed, on the particle size, bulk density, and morphology of the resultant polyacrylate hollow microspheres were investigated and discussed. The mechanism for the formation of the polyacrylate hollow microspheres was proposed. This facile and scalable method for preparing hollow polymer microspheres is expected to be valuable to prepare various polymer hollow structures for widespread application.

The purpose of this study was to determine and compare the effect of oven drying and spray drying treatments on the encapsulation of anthocyanin, flavonoid and phenolic extracted from watermelon rind. The analysis done in this work were as follow: total anthocyanin (TA), total flavonoid (TF) and total phenolic (TPC) content in the supernatant, yield of nanocapsule, Particle Size Analysis, and In Vitro test (test for flavonoid and phenolic release) in the supernatant food. The analysis results showed that the total anthocyanin content in watermelon rind with a spray drying treatment was 0.1113 mg/L, total flavonoid was 0.6159 g/mL, and total phenolic was 0.3410 g/mL. While using the oven, the anthocyanin content was 0.0891 mg/L, total flavonoid was 1.4590 g/mL, and total phenolic was 1.1349 g/mL. As noticed, the total content of anthocyanin resulted by using a spray dryer was greater than by using an oven. However, the total flavonoid and total phenolic resulted by using a spray dryer was smaller than by using an oven. During In Vitro analysis, the results of the release of flavonoid and phenolic resulted by using an oven into the distilled water were much larger and unstable than by using a spray dryer. This is likely because chitosan-Na (TPP) bonds are weak. Additionally, the yield of capsule on the use of spray dryer was 0.6, higher than the use of an oven, which was 0.48. While, the average particle size in the use of a spray dryer was 2.296 μm, smaller than the use of an oven, which was 61.998 μm.

The effect of resin particles on copper x-ray fluorescence was studied. For any given resin size the relationship between copper concentration and x-ray intensity was linear. As the particle size decreased, the x-ray intensity increased for any given copper concentration. The general shape of the curves are similar to the ones predicted by Bernstein for a minor constituent in a power sample. This study indicates that the variation in intensity with particle size can be eliminated by using resins with a mean particle diameter of 56 microns or less.

It is generally considered that the smaller the particle size of insecticides applied as solids, the greater is their effectiveness. Smith and Goodhue (1) arrived at his conclusion after a review of the literature. Woodruff and Turner (4) showed that decrease in particle size of DDT wettable powders increased the toxicity of the residues against house flies, and that correspondingly better results were obtained from the residues of smallest particle size in a field test against potato leafhopper and fleabeetles. Steiner et al. (2), who have done much work on the effect of DDT particle size on codling moth control, stated that for this purpose the optimum surface mean particle diameter for DDT lies between 2.5 and 5 microns.

Spouted bed simulations are usually performed using only one granular phase with a mean particle diameter representing the entire particle mixture, instead of a particle size distribution. In this study, the effect of the particle size distribution is accounted through the simulation of a mixture with five granular phases. The results showed that the particle segregation occurs. Larger particles are more concentrated in the upper region, while the smaller particles are preferably positioned in the lower region of the bed. Computational simulation using CFD method reproduced well the segregation experiments with different participle sizes of sand.

Ideal Process

Spray drying is the most widely used industrial process involving particle formation and drying. It is highly suited for the continuous production of dry solids in either powder, granulate or agglomerate form from liquid feed-stocks as solutions, emulsions and pump able suspensions. Therefore, spray drying is an ideal process where the end-product must comply with precise quality standards regarding particle size distribution, residual moisture content, bulk density, and particle shape. In this study, Momordica sp extract product has been successfully spray dried into micro scale of powder particle and will be used as plant-based insulin. The process optimized using Taguchi method with four factors and three levels has given a good quality of the product. The average of particle size was obtained at about 11 microns.ABSTRAK: Kering sembur digunakan secara meluas dalam proses industri yang melibatkan pembentukan zarah dan pengeringan. Ia amat sesuai dalam penghasilan pepejal kering secara beterusan dalam bentuk serbuk, butiran atau gumpalan daripada simpanan suapan bendalir sebagai larutan, emulsi dan ampaian boleh dipam. Maka, kering sembur adalah proses yang ideal apabila hasil akhir harus mematuhi piawaian kualiti yang tepat berkaitan dengan pengagihan saiz zarah, kandungan kelengsaan sisa, ketumpatan pukal dan bentuk zarah. Dalam kajian ini, produk ekstrak Momordica sp (dikenali juga sebagai peria katak) telah berjaya dikering sembur menjadi serbuk zarah berskala mikro dan akan digunakan sebagai insulin berasaskan tumbuhan.

 The present work aims in evaluate the installation of an equipment of spray drying, by psychrometry technique, analyse the power sources consumption and relates with the productivity of the equipment, by energy auditory. This work consists in comparing the evaporation capacity of a 750 kg/h of water spray dryer and the amount of water that comes from atmospheric air, where the equipment consumes 160 kWh and 80 kg of LGP/h. Therefore, this work demonstrates that to project a spray dryer it must be analysed these water mass values in atmospheric air and be contemplated a dehumidifier in order to prevent so significant and different losses in different periods of the same day.
