In this study, we aimed to investigate chemical and technological characteristics of oven-dried Jerusalem artichoke powder (JAP) to be further incorporated into emulsified chicken meatballs (with/without sodium carbonate) as sodium tripolyphosphate (STPP) replacers. The dietary fiber content of JAP was quite high to improve the health profile of the meat system. JAP samples showed equivalent technological quality to industrial inulin in terms of water-holding, oil-binding, emulsification and gelling abilities. Phosphate-free meatballs formulated with JAP and sodium carbonate had better health impacts compared with phosphate containing meatballs while cooking characteristics were similar. The results showed that oven-dried JAP presented a good health profile and high technological quality to be evaluated as inorganic phosphate replacers in formulation of emulsified poultry products. Keywords: Jerusalem artichoke, oven-drying, emulsified chicken meatball, sodium tripolyphosphate, phosphate-free
在这项研究中,我们旨在研究烘干的耶路撒冷洋蓟粉(JAP)的化学和工艺特性,以进一步作为三聚磷酸钠(STPP)的替代品加入乳化鸡肉丸子(含/不含碳酸钠)中。日粮中膳食纤维含量较高,有利于改善肉质系统的健康状况。JAP样品在保水、粘油、乳化和胶凝能力方面与工业菊粉具有相当的技术质量。在烹饪特性相似的情况下,以JAP和碳酸钠配制的无磷酸盐肉丸比含磷酸盐肉丸具有更好的健康影响。结果表明,烘干的日本大豆具有良好的卫生特性和较高的技术质量,可作为乳化禽产品配方中的无机磷酸盐替代品。关键词:菊芋,烤箱烘干,乳化鸡肉丸,三聚磷酸钠,无磷

The aim of the present work is to determine the moisture diffusion coefficient in peas applying, in a first step, a methodology previously published in the literature by Uddin et al.[1] for determining constant diffusion coefficients taking in account the volume reduction associated to the drying process. Then, in a second step, refine it by means of an optimization step. The optimization step is justified because the methodology of Uddin et al. is based in a solution of the diffusion equation that is not mathematically valid for the drying-shrinking problem. Keywords: : moisture diffusivity; drying-shrinking; peas drying 
本研究的目的是确定豌豆中的水分扩散系数,首先采用Uddin等人[1]先前在文献中发表的方法来确定恒定扩散系数,同时考虑到与干燥过程相关的体积减少。然后,在第二步中,通过优化步骤对其进行细化。优化步骤是合理的,因为Uddin等人的方法是基于扩散方程的解,而扩散方程在数学上对干燥收缩问题无效。关键词:水分扩散率;drying-shrinking;豌豆干燥

Algae drying was carried out using Vacuum Tray Dryer and an Innovative Solar Conduction Dryer. Algae was dried in a Vacuum Tray Dryer at 60°C under varied pressure conditions and makes use of specially designed double condenser system. The open sun drying and solar conduction dryer (SCD) was also used for algae drying. Comparison between open sun drying and solar conduction dryer were done and it was found that the solar conduction dryer gives high performance than the open sun drying. It was also found that, the conductive heat transfer mode plays a crucial role in the solar conduction dryer. Keywords: Vaccum Dryer; Solar Conduction Dryer; Algal Drying

The aim of the present study was to develop an alternative method to the traditional curing process using water vapour permeable bags to obtain a dry-cured pork loin product. The dry-cured pork loins obtained by this mew process showed an adequate hygienic quality and good sensory acceptance. The salting-curing process using water permeable bags requires less manipulation, reduces waste generation and allows greater control during processing. This technique could be an interesting alternative to the traditional processes, improving the hygienic quality of the products and minimizing the environmental impact.Keywords: Dry-cured loin; Salting; Water vapour permeable bags; Physicochemical properties; Sensory.

Lignite, a kind of low rank coal, has the characteristics of high moisture, high volatile, high ash and low heat value. The low-temperature pyrolysis technology is potential to improve the utilization efficiency of lignite. Therefore, a lignite-based energy system integrated with pre-drying and low-temperature pyrolysis was proposed in this paper. To assess the influence of pre-drying process, theoretical models were developed based on thermodynamics, and a case analysis was then performed to get the quantitative effect of pre-drying on efficiency of energy utilization. Results show that pre-drying on PPPS theoretical model can significantly improve the utilization of lignite by 1.46%.Keywords: Lignite; Pre-drying; Low-temperature pyrolysis; Energy efficiency; Case analysis.

Pirarucu (Arapaima gigas Schinz) farming has been encouraged and, among meat preservation techniques, the salting process is a relatively simple and low-cost method. The objective of this work was to study the sodium chloride diffusion kinetics in Pirarucu during wet salting. Limited volumes of brine (20% w/w) were employed with wet salting assays carried at 3, 4 and 5 brine/muscle ratios, and brine temperatures of 10, 15 and 20 oC. The analytical solution of Fick's second law considering one-dimensional diffusion through an infinite slab in contact with a well-stirred solution of limited volume was used to calculate the effective salt diffusion coefficients. Salt diffusivities in muscle were found to be in the range of 2.07 and 8.80 ´ 10-10 m2/s. The wet salting of Pirarucu is greatly influenced by temperature and by the brine/muscle ratio by volume.Keywords: Pirarucu; Arapaima gigas Schinz; salt diffusion coefficients; brine.

Abstract   The objective of this work is to contribute to the generation of a significant advance of the coconut agroindustry in Colombia, for which the process of spray drying was optimized to obtain coconut powder added with functionally active components (CP+PAC) (calcium and vitamins C, D3 and E), food that is framed in the context of functional foods. Initially, the behavior of the physicochemical properties of the coconut during storage at a temperature of 25ºC was evaluated. Then the base emulsion was designed, determining the influence of the composition of emulsions based on coconut milk, on its physicochemical stability, the answer surface methodology was used with a central composite design, considering the independent variables: water/coconut ratio; xantan gum; coconut fiber; terbutilhidroquinona. Subsequently, it was experimentally optimized according to the operating characteristics of the dryer and the product, using a response surface design based on five independent variables: Maltodextrin, air inlet temperature, air outlet temperature, atomizer disk speed and vacuum pressure in the drying chamber. Finally, the stability of the PC+PAC properties was evaluated, using a factorial design based on the independent variables: storage temperature, storage time and packaging. Keywords: coconut, colloidal system, deposit formation, yield, vitamins.

Convective drying is a common process for the treatment of particulate solids also operated in continuous mode. Continuous operation is characterised by operation in steady-state with constant product throughput and constant product quality. Due to external influences, i.e. seasonal or local variations in the properties of the initial wet material, deviations in the product quality can result, for example over- or under-drying, or on-set of unwanted reaction. In this contribution a new feedback control concept is developed that is robust with respect to variations and uncertainties in the drying kinetics of the material and can reject and attenuate process disturbances. Keywords: Process control; drying kinetics; robustness; fluidized bed; yeast. 
对流干燥是处理颗粒固体的常见过程,也在连续模式下操作。连续运行的特点是在稳定状态下运行,产品产量恒定,产品质量恒定。由于外部影响,例如,初始湿材料特性的季节性或局部变化,可能导致产品质量的偏差,例如,干燥过度或干燥不足,或不希望发生的反应。在此贡献中,开发了一种新的反馈控制概念,该概念对材料干燥动力学的变化和不确定性具有鲁棒性,并且可以拒绝和衰减过程干扰。关键词:过程控制;干燥动力学;鲁棒性;流化床;酵母。

The aim of present research was to measure and analyze the dynamic changes of internal pressure in shrinking  vs.  non-shrinking materials during convective drying for the use as a possible process control method. Drying experiments were carried out on wet and fired clay at 50°C and 60°C. In addition, the shrinkage curve was investigated. Experimental measurements show the existence of 4 stages of the process. The comparison of the results for wet and fired clay shows differences in pressure trends. During drying the internal pressure changes from underpressure to overpressure at the level of 3÷5kPa, what correlates well with transition from the first to the second drying period. Keywords: ambient pressure drying; clay; shrinkage; pressure evolution  
本研究的目的是测量和分析收缩与非收缩物料在对流干燥过程中内部压力的动态变化,以便作为一种可能的过程控制方法。在50°C和60°C条件下对湿粘土和烧成粘土进行干燥试验。并对其收缩曲线进行了研究。实验测量表明,该过程存在4个阶段。湿粘土和烧制粘土的对比结果显示出压力变化趋势的差异。在干燥过程中,内压在3÷5kPa水平上由欠压变为超压,这与第一次干燥阶段向第二次干燥阶段的过渡密切相关。关键词:常压干燥;粘土;收缩;压力演化
