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.

Device for evaluating internal quality of vegetable or fruit, method for warm-up operation of the device, and method for measuring internal quality

The present invention relates to an internal quality measuring apparatus for measuring an internal quality of an object, and the apparatus has a conveying device, a detecting device, a light projecting device, a light receiving device, an analyzing device and a pseudo-object member interposing device, and the analyzing device compares light received with a pseudo-object member, with reference data preliminarily stored, and correct a result of the analysis, based thereon.

Measurement apparatus for measuring internal quality of object

A measurement device for measuring an internal quality of a fruit or vegetable with light is intended to be able to obtain the internal quality at higher speed and with accuracy. In the measurement device of the internal quality, transmitted light through the fruit or vegetable is split into a plurality of frequency regions and the measurement device is provided with a plurality of processing circuits for carrying out intensity data calculating operations simultaneously and in parallel for the respective frequency regions.
