EXTRACTION OF 8000 TONS/YEAR OFAVOCADO OIL FROM AVOCADO PULP RONALD MANYAMA SUPERVISED BY MR E MAHOFA .RESEARCH PROBLEM  The intention of this research is to design a process for the production of 8000 tons/year of avocado oil in Zimbabwe  To identify the best avocado oil extraction process for the Zimbabwean context. 2013)  This prompts the need to design and investigate a viable process for the production of avocado oil in Zimbabwe .BACKGROUND  Currently the estates in Zimbabwe are producing 31000 tons of avocadoes per year which are exported to Europe via the Netherlands with France being the major importer  The government of Zimbabwe identified excess avocado as a potential area of innovation in their economic blueprint “ZimAsset” by realizing the need to plant more avocado trees and establishing a plant for producing 14000 tons/year of avocado oil thereby increasing revenue generated from exports of avocado oil (zim-asset.  Low cost process( less than 5 million dollars initial capital investment)  A ready market in Zimbabwe and the export market .JUSTIFICATION  Zimbabwe presents a perfect viability of the project since there will be continuous supply of the raw material.  To carry out an economic cost analysis of the design plant .OBJECTIVES  To provide an economical and effective method for producing avocado oil from avocado pulp.  To design the selected process for the pharmaceutical avocado oil production. RESEARCH QUESTIONS Is the process economical? What is the quality of the oil produced? How much profit can be made? Which extraction process is the best? . involves minimal processing and requires less capital investment. Israel. solvent extraction and hydraulic pressing. The recently developed cold pressing method appear to be the most suitable and beneficial method to extract the avocado oil.LITERATURE REVIEW Only a few countries are actually involved in the production of oil namely Mexico. USA. . It utilizes low temperatures which help retain the healthful composition of the oil. South Africa and New Zealand Avocado oil is used in the cosmetics and pharmaceutical industry Various methods used in the past for the extraction of avocado oil are tube press. EXPERIMENTAL DESIGN Experiment for the smashing of avocado pulp Experiment for the mixing of avocado pulp and water Experiment for the separation of avocado cake. solids and water using a centrifugal sedimentation tank . virgin oil and water in a decanter Experiment for the separation of avocado oil. CHEMICAL ENGINEERING DESIGN  Cold press method will be used to extract avocado oil from avocado oil  Detailed design of the centrifuge will be carried out. Seeds Skins Water STONE REMOVER SKIN REMOVER DISINTEGRATOR MIXER pulp pulp Solids DECANTER Water virgin oil CENTRIFUGE Water Cake . EXPECTED OUTCOMES  A new process for producing avocado oil  A model for the process  A solution to a practical problem . This will prompt an increase in agricultural output from plantations and pharmaceutical industries will benefit from a local supply of the commodity.  Establishing an avocado processing plant for avocado oil has the potential to increase the country’s export revenue .  Avocado stones or seeds can be further processed into fabric dye and ink. .SIGNIFICANCE OF THE RESEARCH  This research project is aligned with Zim-Asset’s value addition and beneficiation matrix by processing avocado fruits into oil thereby adding value. the waste avocado flesh and skins can be further processed into organic fertilizer. INNOVATION  Recycling of waste water from the decanter and centrifuge to the mixer .
