Abstract
A computer driven device has been developed to measure the hardness of fruits easily and accurately. The apparatus can be used for fruits in either destructive or non-destructive conditions. Measurements include external covering layer and internal flesh compressive strength for persimmon and anna-apple fruits and bio-yield point of persimmon fruit. The testing apparatus consists of a step-motor controlled by a computer which drive a probe movement. A step-motor interface 6pin was used for connection to a standard PC from type 486 on. The motor may either be controlled by hand with the computer keyboard or via a program accompanying with the motor. Different types of probes can be used to penetrate or compress the fruit sample. The fruit sample was placed on a load cell under the probe, and the load cell reading was transferred to a digital indicator. Examples of measurements on persimmon and anna-apple were presented to demonstrate the performance of the apparatus.
