油菜籽脱皮是生产冷榨菜籽油的一道关键工序。传统的齿辊式脱皮机在油菜籽脱皮过程中产生的粉末度较大,半仁和整仁率低,增加了皮仁分离难度,降低了原料利用率。所开发的砂辊式菜籽脱皮机通过一对砂辊,采用差速传动,在挤压、剪切和摩擦力的综合作用下,实现油菜籽快速脱皮。与传统的菜籽脱皮机效果相比,这种新型的菜籽脱皮机的脱皮率可达97%~99%,半仁和整仁率更高,粉末度更低。脱皮后的产物有利于籽仁的分离,减小了原料中籽仁的损失。 相似文献

Dehulling characteristics,sensory and functional properties of flours from selected cowpea varieties
Eric O Amonsou Paul A Houssou Esther Sakyi‐Dawson Firibu K Saalia 《Journal of the science of food and agriculture》2009,89(9):1587-1592
BACKGROUND: The knowledge of dehulling characteristics is very important in the selection of cowpeas for flour production. In this study the sensory and functional properties of cowpea flour as influenced by dehulling method (wet and dry/mechanical dehulling) and cowpea variety (white, maroon and mottled) were investigated. RESULTS: White cowpea showed a significantly different (P < 0.05) and higher dehulling rate (DR > 97%) for all dehulling methods. Maroon and mottled cowpeas were poorly dehulled (DR < 10%) when using the wet method (WD). Dry dehulling (DD) was effective on all three varieties (DR > 94%). The highest yield of flour was observed with white cowpea (80% for DD and 96% for WD). The beany odour intensity of flours was dependent on the method of dehulling used. Flour functionality was more significantly influenced by cowpea variety than by dehulling method. CONCLUSION: Dry dehulling could be recommended for cowpea flour production, as this method was found to be more effective on the selected cowpea varieties. Owing to the observed variation in flour functionality among cowpea varieties, the choice of a particular variety for flour production will depend on the intended use of the flour.

Summary The effect of different pre-treatments, i.e. grain scarification, chemical treatment and hot milling, on the strength and dehulling properties of pigeonpea grain was studied by measurement of the forces required for removal of the seed coat from cotyledons and of cotyledons from each other. The dehulling index, dehulling time, product recovery and amount of intact pearled grain were determined after dehulling the pre-treated grain. The results revealed that a significant ( P < 0.05) reduction in seed coat adhesion could be obtained by urea treated scarified grain when hot milled. This, in turn, increased the dehulling index for both the cultivars studied, with subsequent reduction in dehulling time, resulting in a high product recovery of about 81%, and an increased quantity of intact pearled grain of about 39%. 相似文献

Summary Pigeonpea grain (c.v. C11) was used for optimization of dehulling pretreatments. Treatments applied for dehulling were soaking in urea solution and hot milling. Second order polynomial equations were developed to describe a dehulling index and dehulling time. Response surface methodology was also used. Treatment with urea solution was applied to both nonscarified and scarified grain. Different concentrations, solution-to-grain ratios and duration of treatments were tested in five levels as independent factors in the first set of experiments. In the second set, hot milling, heating time and heating temperature were factors in five levels. Hot milling was followed by optimized treatment with urea solution. The levels of these factors were optimized to give a maximum dehulling index and minimum dehulling time, this would yield the maximum product recovery and reduce grain scouring. The results revealed that hot milling after urea treatment of scarified grain increased the dehulling index by about 11% and, consequently, reduced dehulling time by approximately 65% when compared with the treatment followed in commercial mills. This subsequently increased the product recovery and intact pearled grain by about 19 and 23%, respectively. 相似文献
