This document provides information about the industrial process for drying tropical fruits. It discusses the raw materials, specifications for dried fruit products, and trends in the market. It also describes the process of osmotic dehydration where fruit is soaked in a syrup solution so that water leaves the fruit and solute enters. Key factors that affect the dehydration speed are also outlined. Finally, it provides examples of equipment used for drying fruits and results from an experiment drying pineapple slices and dices.

- 4. Summary Sheet Raw Material Products 1. Raw materials specification • Adequate maturity 2. Raw material necessity • Low volumes for pilot plant 3. Problematic • Solve few problems 1. Product specifications • Fruit stability 2. Subproducts • Resulting from osmotic dehydration 3. Trends Ancillary Aspects Inputs: main Syrup or dehydrate osmotic solution • Concentration: 70°BRIX • Aromas and flavors can be reused in other processes of dehydration.

- 7. Summary Sheet Raw Material Products 1. Raw materials specification • Milled to obtain a uniform pulp 2. Raw material necessity • According tray capacity 3. Evolution • Takes place in ovens or in machines 1. Product specifications • Tropical snack type • Less sweet • Crunchy 2. Trends • Import and export Ancillary Aspects • Energetics • Economics • Technicals
- 8. OSMOTIC DEHYDRATION • It is a physiochemical phenomenon. • It makes reference to the passage of solvent but not solute through a semipermeable membrane
- 9. When dipping the fruit in the syrup two effects occur • Water flows out from the fruit to the solution • Solute flows into the fruit Stage in OD: • Dehydration • Impregnation OD is considerated as a pre stage in operations like drying or frezzing.
- 10. Factors that affect the dehydration speed • Permeability and structural features of the celular membrane. • Size of the contact surface with the syrup.
- 11. • Syrup composition and concentration. Syrup concentration affects directly on the speed. • Temperature Increases will make changes in the permeability of the celular membrane and syrup fluency.
- 12. • Stir If the system is stirred, water that has come out is removed from contact with the membrane and will be replaced by concentrated syrup. • Fruta- Syrup ratio When the ratio is 1-1, the speed is lower. • Atmospheric pressure decrease By applying vacuum to the system.
- 13. OPERATION • The osmo-dehydrating agent should be compatible with the fruit. • Immerse the fruit in pieces into the vessel containing the syrup and let stand until it reaches the desired moisture. • The fruit solids ratio increases due to: ▫ Water leaving ▫ Solid income
- 14. • The fruit obtained is often complemented with other preservation techniques.
- 16. Liquid removal by evaporation Agua
- 17. Air in contact with the solid surface transfers enough energy to the water to evaporate. EVAPORATED WATER AIR
- 18. MAIN GOAL Remove water from solid Minimal microbiological growth and spoilage by chemmical reactions.
- 19. FACTORS • Air temperature • Air relative humidity • Air speed • Solid nature
- 20. OPERATION
- 21. The fruit remains inside the drying chamber for a period between 4 and 16 hours depending on the fruit type and the level of dehydration desired. AIR AIR HUMIDIFIED
