DEVICE FOR EVALUATING INTERNAL QUALITY OF VEGETABLE OR FRUIT, METHOD FOR WARM-UP OPERATION OF THE DEVICE, AND METHOD FOR MEASURING INTERNAL QUALITY

摘要

An extremely convenient apparatus for evaluating the inner quality of vegetables and fruits which is small and inexpensive, can be introduced easily even by small-scaled enterprisers, in which an installation place can be changed easily, and safety and promptness of the replacing work of light sources are fully taking into consideration is provided. An apparatus for evaluating the inner quality of vegetables and fruits 1 comprising: a place bed 3 on which vegetables and fruits A are placed; light sources 4, 4 disposed to irradiate vegetables and fruits A; a spectra/detection unit 28 for making spectra in transmission light C having transmitted through vegetables and fruits A to detect the optical strength; an operation processing section 31 for calculating and evaluating the quality evaluation amount of the sugar degree and the ripening degree on the basis of the detection signal; and a display panel 36 for displaying the quality evaluation amount of the sugar degree and the ripening degree, the apparatus capable of being installed on the table, and also being portable. Further, a light source peripheral temperature T1 and an environmental temperature T2 are detected in a manner of a lapse of time, the light source peripheral temperature T1 is compared with a safety setting temperature Tw or the environmental temperature T2, and the fact that the light source temperature is fully lowered is reported.
