Problems solved by technology

However, since nematodes such as anisakis have bodies roughly the same size as fish roe, they sometimes pass through the net, making it difficult to reliably remove them by this method.

Embodiment 1

[0118] to use Figure 1 to Figure 5 The caviar manufacturing apparatus 10 and the manufacturing method of the caviar explained, the experiment of removing Anisakis from the caviar of cod roe (roe diameter of about 1 mm) was performed.

[0119] The first irradiation unit 52 and the second irradiation unit 62 irradiate the first inspection window 75 and the second inspection window 76 with ultraviolet rays having a wavelength of 365 nm at 45 degrees. This was performed with the width D of the flow path 70 being 160 mm. The first sensor 54 and the second sensor 64 are line sensor cameras, and images are taken from the vertical direction of the first inspection window 75 and the second inspection window 76 . The flow velocity of the caviar in the flow path 70 is 60 m / min - 70 m / min.

[0120] The portion of the image generated by the image processing unit 42 that is determined to have foreign matter is enlarged and shown in Image 6 middle. In the image, Anisakis can be confirm...

Abstract

A caviar manufacturing apparatus (10) includes: a flow path forming part (72) that forms a flow path (70) for conveying the caviar in a thinly spread state; and at least two imaged areas (56, 58) , which are provided on the upper surface (72a) and the lower surface (72b) of the flow path forming part (72), and are formed of a material that can transmit predetermined visible light or ultraviolet rays; at least two imaging parts (50, 60) are provided at a position where at least two imaged regions (56, 58) can be photographed, image pickup processing is performed; an inspection unit (40) that performs inspection processing; and a removal unit (80) that is provided in the flow channel forming unit On the downstream side of the conveying direction (100) in (72), removal processing is performed.

Description

technical field [0001] The present invention relates to a method for producing fish roe paste from which foreign matter has been removed, and an apparatus for producing caviar from which foreign matter has been removed. Background technique [0002] As processed caviar products, salt-processed products such as cod roe, salmon roe, salmon roe, herring roe, tobiko roe, cod roe, and Pacific cod roe are often eaten. Salted cod roe is a processed food obtained by salting the ovaries of pollock. The freshness, maturity and size of the raw eggs have a great influence on the quality. The freshest raw eggs are opaque pink as a whole. Among the mature eggs (the ovaries before spawning), the ovaries are normally developed and opaque, and those with round and full ovaries are regarded as high-quality products. When there are many differences in size, they are divided into three classes of large, medium and small by weight, but there are slight differences depending on the fishing grou...
