Single locking cotton feeder for enhancing ginning efficiency of double roller gin

Paper ID- AMA-05-08-2021-10515

A single locking cotton feeder was designed to maintain a constant feed rate of individual pods at the ginning point of the double roller (DR) cotton gin. It consists of a pair of feed rollers, spike cylinders, grids, feed hoppers and distribution chutes. The spike cylinder has spikes, the tips of which are closer to the supply roller than the fixed thickness of cotton and have a ginning interval. The spike cylinder travels at a linear speed greater than the feed roller, whereby the cotton pods held between the feed rollers are hit by the spikes of the spike cylinder, thus ensuring a single locking of the cotton. The effect of single locking on the ginning efficiency of the DR cotton gin was investigated. The degree of unlocking was determined by measuring the change in cotton bulk density before and after passing through the feeder, which decreases with increasing spike cylinder speed. It was found that the DR cotton gin output was increased by 15 to 20% by adopting a single locking compared to the conventional feeding system consisting of an auto feeder and a micro feeder. Cotton quality was also found to improve in color grade. A single locking feeder has proved to be very useful in the cotton gin industry in India.

Maize ear threshing - An experimental investigation

Paper ID- AMA-05-08-2021-10514

Maize harvest was a bottleneck for maize-scale production in the Huanghai Plain. Factors influencing the harvest of corn grains are: the biomechanical properties of corn and the technical parameters of the harvesting machine. In this study, we described how the threshing system is established in the combination of tangential flow and lateral axial flow. Shell grain damage rate was selected as the goal of this experimental study, and variation in the goal was investigated in relation to the biological properties of maize. Threshing experiments were performed to determine the effect of the main biological factor, the water content of the grains. After that, the main technical parameters were defined for the peripheral velocity of the threshing drum. The feed amount was economically maintained at 2.6 kg · s -1, and in this study, the threshing clearance was maintained at 36 mm for corn ears of average diameter. When the water content was 28% or less, the threshing ability of the tangential flow drum was similar to that of the axial flow drum. When the water content was 28% or more, the threshing ability of the tangential flow drum decreased significantly. When the water content is 24-26% and the peripheral velocity of the axial threshing drum is 17.28 m / s -1, the minimum value of the shell grain damage rate of the threshing system is 1.7%, which is the minimum value. there were.

Design, development and performance evaluation of CIAE-millet mill

Paper ID- AMA-05-08-2021-10513

We designed and developed an environmentally friendly CIAE-Millet mill integrated with a pneumatic suction device. It simultaneously threshs minor millets and separates the shells from the threshed population. It is powered by a spindle speed of 960 rpm (for threshing) and a blower shaft speed of 1920 rpm (for pneumatic suction) (1 HP, single-phase motor). Its capacity is 100 kg / h for minor grains of 10-12 mc (wb). The overall dimensions of the machine are 860mmx842mmx1460mm. The performance of the CIAE-Millet threshing machine was evaluated using various types of minor grains. The results showed that the threshing efficiency was in the range of 70-85%.

Design, fabrication and evaluation of a power operated walnut grader

Paper ID- AMA-05-08-2021-10512

Manual size selection of walnuts is a labor-intensive and tedious task, and is even more irrational and inefficient. Therefore, the purpose of this study was to design, manufacture and evaluate a power walnut sorter. Walnuts cultivated in Jammu and Kashmir, India are classified into four grades, all four grades are evaluated for various dimensional, physical, frictional and mechanical properties, and a mechanical system for walnut sorting. Created a database that plays an important role in the design of. A power walnut sorter was developed and tested. The machine consists of a supply hopper, casing, rotary pipe, delivery chute, sprocket, drive chain and control panel. The results of the performance test showed that the sorting error was greatly affected by the feeding speed, the tilt of the sorting machine, and the opening size from the feeding end to the trailing edge. A maximum average sorting efficiency of 96.3% (minimum sorting error 3.7%) was recorded with a supply rate of 400 kg / h and a sorter slope 80. The effective throughput capacity of the machine was estimated to be 337 kg / h. Adoption of this technology will help walnut growers, processors and other stakeholders to produce quality grade walnuts that are acceptable in the competitive market. In this paper, we described the design and performance evaluation of the walnut sorter and the meaning of the obtained results.

Development of mathematical model for predirecting peel mass of cassava tubers

Paper ID- AMA-05-08-2021-10511

The pericarp content of Cassaba varieties required for evaluation of peeling efficiency and meat loss of mechanized Cassaba peelers was investigated based on their water content. Five improved Cassaba varieties, UMUCAS 36, UMUCAS 37, UMUCAS 38, TME419 and TMS 30572, were compared with actual pericarp mass using the developed mechanical and regression mass models. The results obtained were that TME419 at 63.33% water content had an average mass of 585.6 g, 19.13% flesh percentage mass, and 2.33 mm average pericarp thickness, and TMS30572 at 63.5% had an average skin thickness of 499.24 g, 23%, and 2.3 mm: UMUCA S36 has an average mass of 357.48 g, 21.90% pericarp mass, and an average pericarp thickness of 1.6 mm with a water content of 72.69%; while UMUCA37 has an average water content of 84%. With 16.97% pericarp mass, 2.4 mm average pericarp thickness and 430.24 g average mass; and UMUCA38 contains 73.83% average mass of 497.96 g, 2.44 mm average pericarp thickness and 19.77% pericarp mass. It was shown to have by the amount of water. The ANVOA results show that the mass of the pericarp model can approximate the actual response (fruit cortex mass) of the Cassaba varieties beyond the prediction accuracy of 97% or more. These eliminate the fractured work and rigors associated with determining the actual pericarp mass, and remove ambiguity in assessing pulp loss and peeling efficiency in the Cassaba processing system.
