A juice preparation device for a refractometer

Abstract

The invention provides a juice making device for a refractometer. The juice making device comprises a filtering container and a positioning piece, wherein an accommodating cavity for containing pulp is formed in the filtering container; a plurality of filtering holes are densely formed in a wall of the accommodating cavity; a bracket is arranged on the filtering container; the positioning piece comprises a liquid cavity, a drainage groove and a positioning block connected to a lower part of the liquid cavity; the liquid cavity and the drainage groove have communicated communicating parts; thefiltering container is supported in the liquid cavity by the bracket; a bottom surface of the liquid cavity is higher than that of the drainage groove; a groove matched with a side surface of a host machine close to one end of a measuring groove of the host machine of the refractometer is formed in the positioning block; when the groove is positioned and matched with the side surface of the host machine close to one end of the measuring groove in the host machine of the refractometer, an outlet of the drainage groove is located above the measuring groove. The juice making device provided by the invention makes juice conveniently.

Description

technical field [0001] The invention relates to the field of optical instrument measurement, in particular to a fruit juice preparation device for a refractometer Background technique [0002] At present, a type of refractometer appearing on the market needs to drop a few drops of fruit juice into the measuring tank of the refractometer host for detection. This kind of refractometer, which needs to prepare fruit juice before measurement, is used in the laboratories of scientific research institutes or universities. Since there are special juice preparation equipment in the laboratory, there is basically no big problem in using this kind of refractometer. question. However, according to feedback from users such as fruit farmers and melon farmers, the existing refractometers are not suitable for use in fields, exhibitions, and sales sites. When in use, because the entire test device is inconvenient to carry, there is generally no special juice preparation device on site. As ...

Problems solved by technology

However, according to feedback from users such as fruit farmers and melon farmers, the existing refractometers are not suitable for use in fields, exhibitions, and sales sites. When in use, because the entire test device is inconvenient to carry, there is generally no special juice preparation device on site. As a result, the juice test sample cannot be taken, and the measurement work cannot be completed. Therefore, this type of refractometer has great limitations in use scenarios
