Abstract:Mechanization in agriculture plays a significant economic role in increasing the value of agriculture produce. Postharvest processing of agricultural materials is highly essential for its storability and consumption by humans. Machines need to be designed and fabricated to achieve this purpose. The level of agricultural products goes on increasing with mechanization of different post-harvest operations, which aims at achieving timeliness of operations, efficient use of inputs, improvement in quality of produce, safety, comfort and reduction in drudgery of labours. Enhancing the productivity can be increased by reducing losses in pre and post harvest systems by adopting modernization/mechanization and also by increasing the productivity of small and marginal farmers through mechanization and efficient use of agricultural inputs.
Animal Feed Mill (AFM) was developed to process 100 kg of byproduct per day. The commercialized technology, PKV mini dal mill gives the recovery of nearly 72 to 75% and 25 to 28% byproduct (brokens+husk+powder). Amongs the byproduct, the brokens are used for human consumption where as remaining 15-16% is husk and powder. This remaining 15-16% byproduct (husk + powder) contains nearly 18-22% of proteins and hence can be used for preparing Animal feed pellets.
Animal Feed Mill is developed having capacity of 100 kg per day operating at a speed of 28 rpm. The machine consist of hopper, mixing chamber, compaction chamber, die/outlet, power transmission system and frame. Optimum proportion of ingredients for making pellet are byproduct 1kg, 500 ml of water (50% of byproduct) and 50 g of jaggery as binder (5% of byproduct) and 20 g of salt (5% of byproduct)). The unit cost of processing animal feed pellet is @ Rs 12/kg.
