Design and development of thresher for onion umbels (Allium Cepa Variety Aggregatum L.)
Freshly harvested sun-dried onions were peeled on a farm-level peeler to increase seed damage and overcome the heavy labor of traditional peeling methods, which affect germination and vitality factors. High quality seeds can be produced through effective peeling and separation processes. The peeling machine basically consists of a pre-peeling machine, a peeling machine and a blower. The PEG toothed pre-peeler separates the florets from the hard onion head and then sends them to the peeler for the separation of seeds from the florets. The raps bar type peeler separated seeds from floret and good seeds from dust and skin material. The performance of the peeler was evaluated for florette peeling efficiency at different feed rates, ambient and wash air rates, good seed rate collected, seed loss rate, and seed loss. It was concluded from the evaluation that a 6 mm concave gap gives good results at a supply rate of 100 ± 5 kg / h, an ambient speed of 7 m / s, and a washing air rate of 4.5 m / s. The peeler recorded maximum peeling efficiency, good seed rate collected, seed damage and cleaning efficiency of 99.85, 97.70, 1.75 and 96.46%, respectively.
Impact of slice size on kinetic behavior and drying time of fresh-cut apple (Malus domestica)
Drying is a common method for preserving apples. The effect of slice size on the drying rate and drying time of apples (Malus Domestica) was observed. Experiments were performed with slice sizes of 2,4,6 cm. The drying characteristics were examined by drying at 50 ° C for 720 minutes using a temperature cabinet dryer. During the critical drying time, total mass, drying rate, moisture content and moisture ratio were monitored. Using SPSS software, the effect of size on drying time was clarified. The results showed that the drying time decreased with slice size.
Yield and economics attributed study of direct seeding and transplanting method on beds for onion (Allium Cepa L.) cropwith pneumatic precision multicrop planter and manual transplanting method along with rotary tiller cum bed former in indian conditions
The existing area of vegetable planting in India is declining and cannot meet demand due to lack of mechanization. Labor costs associated with sowing and transplanting operations in vegetable planting are very high. Therefore, mechanization in sowing is important for increasing the area of vegetable planting. In this regard, a precision multi-variety transplanter for onion cultivation was evaluated for the selected onion crop, the local sowing variety Punjab Naroyawas. The sowing interval was adjusted to 0.02x0.75 m in the laboratory. A 1.25 m wide floor was created by a rotary cultivator and bedformer, and the average fuel consumption was 6.93 and 7.01 lh -1 for cultivated and non-cultivated soils, respectively. Four lines of onions were sown on each bed using a pneumatic transplanter. Average speed 3. 36Km.H -1, average fuel consumption 2.65Lh -1, average RTR spacing, 20.42cm, the average depth of the seed 2 cm, the average PTP spacing 7.86Cm, average field amount 0. 17Ha.H - It was 1. The mean observation index (PI) of the transplanter was 4.52%. Mean bulbs weight and yield of onion seed by pneumatic precision-mix transplantation machine, 57.45G and 9,562kg. acre relative grafting method -1 and 57.86g and 10,515Kg. Acre -1 was. The cost and time savings of the pneumatic precision high-mix transplanter were 55.12% and 98.53% compared to the transplantation method. The profit-cost ratios for onion sowing by the pneumatic precision high-mix transplanter and the manual transplantation method were 5.11: 1 and 2.62: 1, respectively.
Research on a method to measure and calculate tillage resistance of tractor mounted plough
In the conventional electro-hydraulic hitch control system, the method of measuring the tillage resistance could not accurately reflect the tillage resistance of the mounted plow. We analyzed the method of measuring the tillage resistance and proposed a method of measuring the tillage resistance of the mounted plow by the action signal of the hinge points of the upper link and the lower link. The tillage resistance analysis matrix was constructed using the spatial vector mechanics analysis principle. The resistance measurement system prototype was developed on the JINMA 1204 tractor. We analyzed the ill-conditions of the analysis matrix and developed a calculation program for tillage resistance. A field test of the tillage resistance measurement system was carried out, and the test result showed that the correlation coefficient between the measured value of the tillage resistance measurement system and the test value was 0.79, which showed a strong correlation. Resistance is effective. Through the calibration of the resistance measurement system, the maximum reference error between the tillage resistance measurement value and the tillage resistance test value is 5.7%, which meets the measurement requirements for electro-hydraulic hitch control of agricultural tractors.
Designing and testing an innovative soybean seed grader with oval-hole screen type
In order to improve the performance of the existing soybean seed sorter using the commonly used spherical hole screen type, an innovative sorter using the oval hole screen type was designed and tested. The design process was carried out at the Agricultural Mechanization Laboratory, while the performance testing process was carried out at the Muneng Laboratory of the Legume and Tuber Crops Institute (ILETRI) in Indonesia from January to December 2011. For comparison, a sorter designed using an elliptical hole screen type (hole size: 6,5,4 mm) and a spherical hole screen type (hole size: 6,5,4 mm) was used at both ends and the screen with a screen inclination of 10 °. Spring-supported at both the center. The sorter was driven by a 5.5hp gasoline engine and operated at a pulley speed of 432rpm. The performance of the sorter was evaluated by using large seed size varieties of soybean seeds (Grobogan and Argpmulyo) and medium seed size varieties (Wills). The results show that the sorter (ILETRI sorter) with an elliptical hole screen type (hole size: 6,5,4 mm) was used for both types of soybean seeds (large and medium size) compared to the spherical hole screen type. On the other hand, it was shown that the seed quality grade (Gi) can be increased. The capabilities of the ILETRI sorter were higher for all large seed size varieties: Grobogan (656 kg / hr) and Argpmulyo (678 kg / h) compared to medium seed size varieties: Wills (437 kg / h). Furthermore, by using this sorter, the seed grade can be divided into two grades (G1 and G2) with respect to Grobogan, and the ratio of G1 and G2 is 56.6% and 37.8%. The average diameters were 9 mm and 8 mm, respectively. On the other hand, for the other two varieties (Argomulyo and Wills), the seed grades were divided into three grades, namely G1, G2 and G3. On average, the percentage of G1 and seed diameter were 51.9% and 6.6 mm for Argomulyo and 14.6% and 5. for Wills. It was 1 mm. The G2 ratio and seed diameter for Argomulyo were 33.7% and 6.5 mm, while for Wills they were 23.8% and 6.0 mm. However, the ratio of G3 to Argomulyo and Wills was 14.4% and 56.15%, respectively, and the average seed diameters of both varieties were 6.4 mm and 4.8 mm, respectively. The indicators of seed homogeneity were similar for both types of seeds with a coarse: medium: fine ratio of 10: 0: 0, suggesting that the level of homogeneity reached 100%. However, on the other hand, the seed survival rate met the criteria for seed elongation (70%). On average, the seed viability of Grobogan, Argomulyo and Wills was 82.5%, 87.1% and 74.6%, respectively. With a price of Rp16 million / unit and a wage of two drivers with Rp150,000 per day, the cost of the ILETRI sorter is Rp52 / kg, the break-even point is 103t / year, and the rate of return is 6.0. In months, the net present value is Rp73.9 million, the profit-to-cost ratio is 1.67, and the internal rate of return is 199.8%. In conclusion, technically and economically, the ILETRI sorter has a beneficial prospect of being applied in soybean seed producers. The ILETRI soybean seed sorter is patented in Indonesia with patent number: S002012000 65. (Translation author abstract) Meet the criteria for seed elongation (70%).
