Scope and Importance of Material Handling, Crop Process Engineering | Crop Process Engineering Notes - Agricultural Engg - Agricultural Engineering PDF Download

Material handling includes a number of operations that can be executed either by hand (manual) or by mechanical means or devices to convey material and to reduce the human drudgery.


After harvesting, the grains are moved, transported or conveyed from place to place. In earlier periods all these operations were manual. The grains were threshed and bagged by human labour. Mechanical handling delivers aim to lighten the work of human labour. Grains were transported several times through storage and milling plants, and the milled food products were conveyed manually to customers. Thus, grains were handled too much involving increased cost and human drudgery. Now a day, some mechanical devices have replaced human labour, other supplement it or in some case make possible to handle larger quantities of grains per unit human labour. The most common types of mechanical devices for grain handling are;

1 Belt conveyor

2 Bucket elevator

3 Screw Conveyor

4 Pneumatic conveyor

The selection of proper conveying system is important for ease in operation and getting desired capacity for a particular product. The following principles should be taken into account before selecting conveying systems.

  1. The conveying device has to be selected according to the characteristics of the materials being conveyed.

  2. In a conveying system possibility of use of gravity should be taken into consideration.

  3. The stability of the conveyor must be ensured under all normal working and climatic conditions.

  4. The dead load of the conveyor should be low in relation to the weight of transported product.

  5. The capacity of handling/conveying equipment should match with the capacity of processing unit of units.

  6. Spillage of conveyed products should be avoided.

  7. Pollution of the environment due to noise or dust by the conveying system should also be avoided.

FAQs on Scope and Importance of Material Handling, Crop Process Engineering - Crop Process Engineering Notes - Agricultural Engg - Agricultural Engineering

1. What is material handling in the context of agricultural engineering?
Material handling in agricultural engineering refers to the movement, storage, protection, and control of materials and products throughout the agricultural production process. It involves the use of various equipment, techniques, and systems to efficiently handle materials such as crops, seeds, fertilizers, and machinery.
2. Why is material handling important in agricultural engineering?
Material handling is crucial in agricultural engineering as it helps optimize productivity, reduce costs, ensure product quality, and improve overall efficiency. Proper material handling techniques can minimize the risk of damage, loss, and contamination of agricultural products, ensuring that they reach the market in optimal condition.
3. What are the different methods and equipment used for material handling in agricultural engineering?
There are several methods and equipment used for material handling in agricultural engineering, including: - Conveyors: These are used to move materials horizontally or vertically, ensuring a continuous flow of products. - Forklifts: Forklifts are commonly used to lift and transport heavy loads, such as bags of crops or machinery. - Storage systems: These include silos, bins, and warehouses designed to store crops, seeds, and other agricultural products. - Automated systems: Advanced technologies such as robotics and computer-controlled systems are increasingly being used in material handling to automate processes and improve efficiency.
4. How does material handling impact crop process engineering?
Material handling plays a significant role in crop process engineering by facilitating the movement and processing of crops throughout the production cycle. Efficient material handling systems ensure timely and accurate delivery of crops to processing facilities, reducing delays and optimizing the use of resources. It also helps maintain the quality and integrity of crops during processing, leading to higher yields and better end products.
5. What are some challenges faced in material handling in agricultural engineering?
Some challenges faced in material handling in agricultural engineering include: - Seasonal variations: The demand for material handling equipment and techniques fluctuates with the seasons, requiring flexible and adaptable systems. - Weather conditions: Adverse weather conditions such as rain, snow, or extreme temperatures can affect material handling operations, requiring additional precautions and equipment. - Safety concerns: Material handling involves heavy machinery and equipment, posing potential risks to workers. Implementing appropriate safety measures is crucial to prevent accidents and injuries. - Sustainability: There is a growing need for sustainable material handling practices in agricultural engineering, considering factors such as energy efficiency, waste reduction, and environmental impact. Finding innovative solutions to minimize resource consumption and emissions is important.
