Abstract

Aren (Arenga pinata) tree is one type of palm plant that produces fruit, sap and starch or flour in the trunk. Industries aren flour usually in small and medium industries is dried by conventional method with dried under the sun. The main constraint is the low drying speed. Therefore, in this study aren flour with a water content of 40% was dried using a pneumatic dryer to moisture content below 15% (wet base). The aim of this research is to analyze the influence of drying air temperature, drying air flow rate and feeding speed to drying speed and energy analysis. Energy analysis was performed to determine the performance of pneumatic dryers. The energy analysis itself is done in the form of energy utilization and energy efficiency. The results show that the increase of dryer temperature from 60 to 100 will increase the utilization of energy from 0.61 to 1.39 J / s, energy efficiency is 33.4-45.1%. the results of a proximate analysis, an ash content of 0.39 grain fiber 0.18 white degree 92.93% which already fulfill SNI standard of Aren flour.

Highlights

Aren tree is one type of palm plant
Coconut tree trunked clean with old leaves that loose, aren tree trunk is very dirty because the stems are clad in fibers, so that the old leaves bark is difficult to be taken or out of the stem
The results show that all test criteria have met the quality standards of aren flour as a food ingredient, for crude fiber the results showed still higher than required because of the fibers are still included in the flour because the content of aren flour is very high in which aren flour obtained from tree trunks

Summary

Introduction

Aren tree is one type of palm plant. All parts of the tree can be used and have economic value. Starting from the physical parts (roots, trunk, leaves, fibers etc.) as well as the results of its production (nira, flour and fruit). The tree is not spiny, unbranched, the height can reach 25 meters and the diameter of the tree can reach 65 cm [1]. This plant is almost similar to the coconut tree. Aren tree trunks are often overgrown by many types of ferns [1]
