Abstract/ Executive Summary:

A mini oil expeller was designed and fabricated at the workshop of the Farm Machinery & Postharvest Process Engineering Division of Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the period of 2016-2017. The overall dimension of the expeller 1200×570×1280 mm and power required to operate the machine was 12.5 hp diesel engine. Four kilograms of mustard were expelled per batch. The average engine and machine speeds were 1500 and 15 rpm, respectively. The average oil recovery was 35.0%. The expelling capacity of the oil expeller for mustard was 12.0 kg/h. The main problem with the previous mini oil was that it was stacked during operation. The problem was solved in the improvement of the present oil mill. The improved oil mill ran smoothly during operation. The oil mill may be operated by a power tiller and it should be movable. Then the machine needs to be demonstrated in the farmers’ field for its dissemination.

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Farm Mechanization

Commodity: Expeller

Objectives:

a) To design and fabricate of a mini oil expeller for expelling of oil seeds b) To evaluate performance of the oil expeller for expelling of oil seeds

Methodology:

A mini oil expeller was designed and fabricated at the workshop of the Farm Machinery and Postharvest Process Engineering (FMPE) Division of Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during the period of 2016-2017. It was made of locally available materials. The materials used for fabrication of different parts of the machine were MS plate, MS angle bar, MS flat bar, MS rod, MS sheet, cast iron, ball bearing, pulley, flat belt, etc. The functional parts of the machine are the feeding tray, rotor casing, spiral screw, shaft, cone, pulley and flat belt. The oil expeller was operated by a 12.5 hp diesel engine. This oil expeller was set on the floor and power was transmitted from a diesel engine by a flat belt. At least four kilogram of oilseeds is required for its operation. Pictorial views of the operation of mini oil expeller. At first, the engine was started and the speed of the engine was adjusted so that the speed of the expeller was reduced to about 15 rpm. Then 4.0 kg of mustard seeds (Tori Sharisha) were fed into the feeding hopper and delivered to the rotor casing to be crushed. Inside the rotor casing, there was a spiral screw that moved the seed forward for pressing and oil was extracted from the seeds. Oil was collected below the rotor casing. When seeds were transformed into the cake, they came out through the outer surface of the cone. The speed of the expeller was reduced gradually to 12-13 rpm for final extraction of oil. The partially crushed oil was fed three times until all extractable oil was extracted. The starting and ending time was recorded. The weight of mustard, oilcake and oil (after 24 hours of sedimentation) was also measured.

Achievement/Findings:

The average engine and machine (oil expeller) speeds were 1500 and 15 rpm, respectively. About 1.40 kg of oil (crude) was obtained from 4.0 kg of mustard. Oil extraction from mustard was 35.0%. The capacity of the machine was 12.0 kg/h. The machine ran smoothly without stuck during operation. The oil expeller may be operated by a power tiller and it should be movable. Then the machine needs to be demonstrated in the farmers’ field for its dissemination.
