Department of Post Harvest Engineering typically focuses on the application of engineering principles and technologies to address challenges related to the post-harvest handling, processing, storage, and preservation of agricultural and horticultural products. The aim is to enhance the quality, safety, and marketability of harvested crops. 

Post Harvest Handling: Techniques for handling crops after harvest to minimize damage and maintain product quality. This may include sorting, grading, and packaging procedures.

Storage Technology: The design and optimization of storage facilities for crops, considering factors such as temperature control, humidity, ventilation, and protection against pests and diseases.

Cold Chain Management: Strategies for maintaining the quality of perishable products through a controlled temperature chain, from harvest to consumption. This is particularly important for fruits, vegetables, and certain food products.

Drying and Dehydration: Methods for removing moisture from crops to prevent spoilage. This may involve the use of drying technologies such as air drying, solar drying, and freeze-drying.
