One form of evaluation apparatus comprising a plurality of light sources vertically arranged by one side of a carrier line in width direction Y perpendicular to carrying direction X of the carrier line; and a light-receiving section arranged by an opposite side of the carrier line in the width direction Y perpendicular to the carrying direction X of the carrier line. Another form of evaluation apparatus comprising a plurality of light sources capable of irradiating measuring lights of given quantity; means for regulating the quantity of measuring lights from the light sources in accordance with sizes of vegetables and fruits; a light-receiving window of given openness provided in a carrier line, the light-receiving window capable of leading measuring lights having been transmitted through the vegetables and fruits toward a light-receiving section; and means for regulating quantities of transmitted light provided to the light-receiving window, the means for regulating quantities of transmitted light being capable of regulating the openness of the light-receiving window.

Apparatus and method for evaluating the interior quality of fruits and vegetables

Method for evaluation of vegetables and fruits and evaluation apparatus therefor

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 comprising: a place bed on which vegetables and fruits A are placed; light sources disposed to irradiate vegetables and fruits A; a spectra/detection unit for making spectra in transmission light C having transmitted through vegetables and fruits A to detect the optical strength; an operation processing section 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 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 T and an environmental temperature T are detected in a manner of a lapse of time, the light source peripheral temperature T is compared with a safety setting temperature T or the environmental temperature T , and the fact that the light source temperature is fully lowered is reported.
