Portable type cucumber pesticide residue detecting, sampling and freshness-retaining box

Abstract

The invention relates to a portable type cucumber pesticide residue detecting, sampling and freshness-retaining box, and belongs to the field of vegetable pesticide residue detecting matching equipment. The portable type cucumber pesticide residue detecting, sampling and freshness-retaining box comprises a box body and a box cover, wherein the inner wall of the box body is provided with a thermal insulation layer; an inner cavity of the box body is divided into a regulating chamber and a storage chamber; a nitrogen generating system and an air compressor as well as a power supply system are arranged in the regulating chamber; the air compressor is connected with a nitrogen gas path pipeline and an air path pipeline in parallel; a placing slot is formed inside the storage chamber; a stable tray is arranged in the placing slot; and the bottom of the stable tray is provided with a cold storage chamber with a double-layer cavity structure. The portable type cucumber pesticide residue detecting, sampling and freshness-retaining box is provided with the nitrogen generating system and the stable tray capable of refrigerating and controlling a temperature, so that the activity of a cucumber sample and volatilization of volatile pesticide residues are effectively reduced, and the consistency before and after test material sampling is guaranteed. Freshness-retaining effect of cucumber long-distance sampling detecting and field sampling is improved, and guarantee is provided for accuracy of cucumber pesticide residue detecting. The portable type cucumber pesticide residue detecting, sampling and freshness-retaining box is simple in structure and is convenient to operate, so that cucumber pesticide residue detecting and sampling speed is increased.

Description

technical field [0001] The invention relates to the field of supporting equipment for detecting pesticide residues in vegetables, in particular to a portable fresh-keeping box for detecting and sampling cucumber pesticide residues. Background technique [0002] Cucumber is a year-round herbaceous plant belonging to Cucurbitaceae Cucurbitaceae, which has a cultivation history of more than 2,000 years in my country. Cucumber is easy to eat, rich in vitamins A, C and various beneficial minerals, and is one of the main vegetable crops in my country. In recent years, with the adjustment of my country's agricultural industry structure and the rapid economic development, great changes have taken place in the cultivation of cucumbers in my country. The area has expanded rapidly, the varieties have become more abundant, the division of cultivation crops has become more detailed, and annual production has been achieved. [0003] Due to the high profit of cucumber planting and the rel...
