蓖麻籽螺旋压榨制油影响因素分析及其摩擦系数的计算

蓖麻籽是一种重要的高含油、低含水工业油料。采用螺旋压榨法制油时,其操作温度直接关系到油品质量和制油效果。蓖麻籽经过螺旋压榨后,其主要内含物蓖麻油以液态形式聚集并在压力的作用下从蓖麻籽中分离出来,这个过程主要受内外两方面因素的影响。蓖麻籽组成、入料形态和是否进行升温调质等多种因素直接决定了蓖麻籽螺旋压榨的效果;螺旋榨油机的榨轴转速和出饼口孔径直接制约了油料输送速率和出油效果。通过多工况下的组合试验及均值化处理,得到了单螺旋榨油机的实际输送速率和当量摩擦系数等参数。蓖麻籽直接进料压榨,在榨轴平均转速为50.25 r/min、出饼口孔径5 mm时,平均压缩比为4.28、输送效率为4.41 kg/h、饼残油率14.86%。

Screw press extraction of almond (Prunus dulcis (Miller) D.A. Webb): Oil recovery and oxidative stability

The objectives of this work were to study the combined effects of seed moisture content and pressing temperature on oil recovery and quality parameters of almond oil (AO) and to evaluate the effectiveness of natural (rosemary extract and ascorbyl palmitate) and synthetic antioxidants (TBHQ) on the oxidative stability of AO analyzing chemical changes during an accelerated thermo-oxidation assay. A factorial arrangement was conducted, in pressing experiments, in order to study the combined effects of seed moisture content (4, 6, 8, 10 and 12% (w/w)) and pressing temperature (20, 40 and 60 °C) on oil recovery and quality parameters. Oil recovery increased significantly as moisture content raised. The highest oil recovery (79.3%) was obtained at 8% (w/w) seed moisture content and 40 °C pressing temperature. All extraction conditions employed were compatible with an acceptable chemical oil quality.     

Optimisation of consolidation and whey drainage during the process of Paneer pressing

Test cells of various profiles (circular, square, rectangle) were designed to conduct experiments to evaluate consolidation mechanism and drainage of whey during Paneer pressing. The milk coagulum was subjected to different pressure levels (1.0–3.5 kg/cm²) for different time periods (300, 600, 900 s). The non-dimensional whey expression ratio (WER) during pressing followed an exponential relationship with pressure, and the maximum value for WER ranged from 20.5 to 23.0 for the test cells. The visco-elastic consolidation process was adequately described using Kevin–Voigt models. The void ratio, porosity and consolidation ratio were estimated by the Terzaghi consolidation test.     

Pressing and supercritical carbon dioxide extraction of walnut oil

The objective of this study was to evaluate the oil extraction process from walnut seeds by pressing followed by extraction with supercritical CO₂. In pressing experiments, a factorial arrangement was conducted in order to study the combined effects of seed moisture content (2.5%, 4.5% and 7.5%) and pressing temperature (25, 50 and 70 °C) on oil recovery and quality parameters. For all conditions tested, the oil quality compared well with that of cold-pressed walnut oil. Oil recovery increased significantly as moisture content raised. Highest oil recovery (89.3%) was obtained at 7.5% moisture content and 50 °C temperature. The cake resulting from pressing at these conditions was extracted with CO₂ in a high pressure pilot plant with single stage separation and solvent recycle. The effects of two different pressures (200 and 400 bar) and temperatures (50 and 70 °C) with regard to oil yield and quality, and time required for extraction were analyzed. At each condition, the extraction rate changed with the mass of solvent and extraction time. At first, the mass of oil extracted was determined by the oil solubility in CO₂ and a linear relationship was observed, where the slope results in the solubility of oil in CO₂ at the experiment conditions. After that, the extraction rate was governed by solubility and diffusion, and continuously decreased with time. The colour changed along the extraction from a whitish clear product to a yellow one. Tocopherol and carotenoid contents were significantly higher than those obtained by pressing. Extraction conditions did not affect significantly the fatty acid composition.
