Introduction :
    The Department of Processing and Food Engineering is mainly engaged in teaching to Under Graduate and Post Graduate courses. It offers various courses related to Post Harvest Technology such as Drying and Dehydration, Heat and Mass Transfer, Seed Technology, Storage Engineering, Environmental Control Engineering, Farm buildings and Animal Housing, Physical Properties of Biological Materials, Electrical Engineering and Food Science etc. to the UG and PG students. The research project based on local and future needs of the farmers and entrepreneurs are given to the final year under graduate and postgraduate students as a part of their academic research work. One ICAR scheme viz., All India Coordinated Research Project on Post Harvest Engineering Technology is also running under this Department and associated with research and extension activities related to post harvest operations of cereals, pulses oilseed fruits & vegetables. Other schemes running in the department are Post Harvest Technology of Important crops of Saurashtra, Enzymatic Pre-treatment in the Processing of Pigeon pea, Mega Seed Project, Canning of fruits and vegetables and also facilities of Low Temperature storage of fruit products.
    Department is having Storage Engineering, Agricultural Processing, Bio-chemical, Size Reduction, Drying, Engineering properties Laboratories, to provide demonstration and training.  Many farmers, women and local artisans often visit the department to gain knowledge.  The working principle and its usefulness of the machines, equipments are demonstrated to the visitors.  They are also familiarized with the new developments like Different Storage Structures, Onion storage structures, Cleaning and Grading machines, and different type of Mills, Dryers and Separators, Fruit and vegetable graders, Sapota Cleaners, etc.
     Agro Processing Centers run by the AICRP on Post Harvest Technology (ICAR) at Villages TadkaPipaliya  (Ta. Bhesan Dist. Junagadh), Virol  (Ta. Mangrol, Dist. Junagadh), Loej (Ta. Mangrol, Dist. Junagadh), Vadala (Ta. Talala, Dist. GirSomnath) and Chotila (Dist. Rajkot) are the ongoing demonstration centre for value addition and income generation to the farmers. It also provides latest know how on post harvest aspects of various crops as well as opportunities to farmers to become producer cum processors at their doorstep.
     The department participates in Agricultural Fares, Exhibitions, and Farmers day organized by Universities or State Governments or other agencies and arranges the demonstration of Processing Technologies etc. to the farmers.
    The Senior and Experienced Professors or Scientists are delivering lectures on the special topics related to the Post Harvest Handling / Management, Value Addition etc in the Short Term Ttraining Programmes arranged by the University /State Government for the benefits of the farmers, technicians and village artisans.

EXTENSION ACTIVITIES
Establishment of Agro Processing Centers
   To create awareness towards importance of post-harvest technology in strengthening the rural economy and improvement in livelihood of the rural masses by creating rural employment, Agro Processing Centers are established to cater the processing facilities at rural level for value addition under AICRP Post Harvest Engineering & Technology. Such Agro Processing Centers are managed by Village Cooperative Society with the technical guidance of the faculty. The location based processing facilities are created by the funding from ICAR. These APCs also provide effective platform for the popularization of new technologies to farmers by conducting various extension programmes. Presently, five such centers i.e. TadkaPipaliya  (Ta. Bhesan Dist. Junagadh), Virol  (Ta. Mangrol, Dist. Junagadh), Loej (Ta. Mangrol, Dist. Junagadh) and Vadala (Ta. Talala, Dist. GirSomnath) and Chotila (Ta. Chotil, Dist. Surendranagar) are running successfully.
Participation in Government sponsored Extension Proramme
Krushi Mahostav
   Faculty and Scientists of the department actively participate in the KrushiMahostavProgramme organized by the state Government every year and also taking part in the exhibition, seminar, krushigosthi etc. arranged during the programme.
Mera Gaon Mera Gaurav
   Scientists of the department regularly visit the adopted villages under MeraGaonMera Gaurav programme to promote the direct interface of scientists with the farmers to provide farmers with required information, knowledge and advisories.
Demonstration of processing machineries
   The demonstration of the processing machineries developed by the department as well as other centres of AICRP on PHET are arranged at villages as per the need of farmers in collaboration of AGAKHAN, ATMA and other such NGOs.
On and off campus extension programmes
   The Senior and experienced Professors or Scientists are delivering lectures on the special topics related to the post harvest handling / management, value addition etc. in the short term training programmes arranged by the university for the benefits of the farmers, technicians and village artisans. The department itself also organize such short term training programme at on and off campus. Many farmers, women and local artisans often visit the department to gain knowledge. The working principle and its usefulness of the machines, equipments are demonstrated to the visitors. The department participates in Agricultural Fares, Exhibitions and Farmers day organized by Universities or other agencies and arranges the demonstration of Processing Technologies to the farmers. 
   Department has organized one day Workshop on Application of Nuclear Energy in Agriculture and Food on September 27, 2019; World Food Day on October 16, 2019 and AFPMMM 2019 (Agricultural and Food Processing Machinery Manufacturer Meet) on November 27, 2019 for the benefit of machinery manufacturers.
ABSTRACT OF PUBLICATION, PARTICIPATION, PRACTICAL MANUAL, AWARD, POPULARIZATION OF TECHNOLOGIES etc. (2009-10 to 2022-23)
Future plans/ thrust areas:
1. Research on Post Harvest Technology of important crop of Saurashtra.
2. Agricultural Polytechnics for Agro Processing.
3. Drying and dehydration of horticultural Agricultural Produced.
4. Farm level pre cooling technique of Horticultural Product.
5. Extraction of essential oil from spices.
6. Development Agricultural crops residue fired dryer for drying spice crops.
7. Women bio resources complex on food and fruit processing.
8. Strengthening of post harvest technology and value addition.
9. Degree programme in Food Process Technology.
