“…The moisture were determined using standard air oven method at a temperature of 105±1°C and drying time of 24 h (ISI 1966). Friction angle was measured by slope method i.e., pods, husks and seed are kept on a glass surface and raised slowly upward direction to note down the angle side (Güzela et al 2005;Aydin 2003). All the data was evaluated statistically.…”

A small, continuous power operated machine with a capacity of 132 kg/h was designed, fabricated and evaluated its performance for separation of annatto (Bixa orellana L.) seeds from freshly harvested pods. Physical and engineering parameters of annatto pods and seeds were evaluated to design a machine. The densities of pod, seed, and husk are 134.7 to 186.0 kg/m 3 , 1206 to 1253.9 kg/m 3 , 317 to 381.4 kg/m 3 respectively. The moisture content of seeds were in the range 18.83 -20.1 % (db) and pod 8 to 10 % (db). Bixin content of seed was in the range 1.34 to 1.765 %. The friction angle for pod, seed, and husk lies between angle 30.15°to 35.76°. Breaking force was 98 N at a span of 14.5 mm. The machine consisted of concentric cylinders and beaters with different pitch of 40, 45 and 50 mm and a length of shaft is 800 mm. The actual machine output was observed to be 132.5 kg/h. Maximum bixin content was found to be retained at 300 rpm.

“…Kernels (seeds) contain rich edible oil, proteins, amino acids, and vitamin E, and are consumed worldwide as edible nut, peanut butter, or candy, and peanut oil extracted from the seeds (Bertioli et al 2016 ; Ozudogru et al 2013 ). The shelling of peanut hull is the first step needed to transform the peanut materials into a product (Guzel et al 2005 ). Shelling percentage (weight of kernels/weight of pods) significantly varied among peanut varieties.…”

Key message A total of 204,439 SSR markers were developed in diploid genomes, and 25 QTLs for shelling percentage were identified in a RIL population across 4 years including five consistent QTLs. AbstractCultivated peanut (Arachis hypogaea L.) is an important grain legume providing edible oil and protein for human nutrition. Genome sequences of its diploid ancestors, Arachis duranensis and A. ipaensis, were reported, but their SSRs have not been well exploited and utilized hitherto. Shelling percentage is an important economic trait and its improvement has been one of the major objectives in peanut breeding programs. In this study, the genome sequences of A. duranensis and A. ipaensis were used to develop SSR markers, and a mapping population (Yuanza 9102 × Xuzhou 68-4) with 195 recombinant inbred lines was used to map QTLs controlling shelling percentage. The numbers of newly developed SSR markers were 84,383 and 120,056 in the A. duranensis and A. ipaensis genomes, respectively. Genotyping of the mapping population was conducted with both newly developed and previously reported markers. QTL analysis using the phenotyping data generated in Wuhan across four consecutive years and genotyping data of 830 mapped loci identified 25 QTLs with 4.46–17.01% of phenotypic variance explained in the four environments. Meta-analysis revealed five consistent QTLs that could be detected in at least two environments. Notably, the consistent QTL cqSPA09 was detected in all four environments and explained 10.47–17.01% of the phenotypic variance. The segregation in the progeny of a residual heterozygous line confirmed that the cpSPA09 locus had additive effect in increasing shelling percentage. These consistent and major QTL regions provide opportunity not only for further gene discovery, but also for the development of functional markers for breeding.Electronic supplementary materialThe online version of this article (doi:10.1007/s00122-017-2915-3) contains supplementary material, which is available to authorized users.

“…The statistical results of peanut broken pressure are shown in Fig. 3, which indicates that the mean pressure during manual shelling process is 40.6 N. The ability of a peanut seed to withstand squeeze at the top and bottom ends is relatively weak [6], which suggests that the ends should be protected during shelling (Fig. 4).…”

Peanut is an important economic crop and there are strict requirements for the degree of damage to peanut seed, seed coat and germ, which are difficult to guarantee by an ordinary sheller. Manual operation often cannot satisfy modern agricultural production due to heavy labor intensity, low efficiency and work quality. For the above reasons, a suitable peanut shelling machine is needed to replace manual operation and conventional sheller. A peanut shelling machine has been designed, which imitated manual peanut peeling method. The mechanical structure of the peanut shelling machine consists of a frame, a feeding mechanism, a pneumatic gripper and peanut shelling positioning mechanism. The control system is composed of a MCU, LCD 12864 liquid-crystal display, and keys. Experimental results showed that, the peanut shelling rate is 20/min and the success rate is 92.3%. Furthermore, it provided a new approach to achieve automatic peanut shelling operation and well-satisfied agricultural production.
