Vegetable oil sampling device and sampling method

Abstract

The invention discloses a vegetable oil sampling device. The vegetable oil sampling device comprises a control box with a bracket and a sampler, a storage battery, a display screen, an integrated circuit board, a control unit and an electric capstan are arranged in the control box shell, a support is arranged below the electric capstan outside the control box and used for being fixed to the top ofthe oil tank, the control box is connected with the sampler through an oil-proof steel-wire-containing cable, and the sampler is driven by the electric capstan and the control unit in the control boxto descend, ascend and hover in the vegetable oil tank. The invention further discloses a vegetable oil sampling method, through the control unit of the sampling device, automatic measurement of theoil storage height of the vegetable oil tank can be achieved, 1 / 10, 1 / 2 and 9 / 10 height sampling positions are automatically calculated according to national standard requirements, the sampler automatically reaches a designated position, and automatic sampling work is achieved.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a vegetable oil sampling device and a sampling method. Background technique [0002] During the production, storage and processing of vegetable oil, in order to ensure product quality, sanitation and quality inspections are required. As the storage time of vegetable oil prolongs, the quality of vegetable oil at different heights in the oil tank will also vary. Take representative samples from the layers or parts of the vegetable oil tank. The national "Grain and Oil Quality Inspection Sampling Management Measures" stipulates that samples should be taken from the upper, middle and bottom layers of the vegetable oil tank respectively. / 10 were sampled separately, and the mass ratio of the top, middle and bottom three layers of cuttings was 1:3:1". [0003] At present, vegetable oil sampling in my country is usually performed manually, and manual sampling needs to be repe...

AI Technical Summary

Problems solved by technology

[0003] At present, vegetable oil sampling in my country is usually performed manually, and manual sampling needs to be repeated for more than 3 times (i.e. sampling at the top, middle, and bottom respectively). The operation is complex, time-consuming, and labor-intensive, and requires the cooperation of multiple people to complete.

The oil tank is usually high, the position of the sample is not easy to accurately grasp, and the representativeness of the sample is insufficient, which affects the detection effect; the sample rope is easy to be entangled and knotted, and the oil stain attached to the sample rope is difficult to remove, and it is easy to contaminate the sample when the sample is repeated continuously ;Vegetable oil has poor oxidation stability, and is usually stored in low oxygen. If the sampling time is too long, the oxygen in the oil tank will increase, which will affect the storage safety of vegetable oil.

my country produces and imports a large amount of vegetable oil every year. The low efficiency, unfriendly working environment and low degree of automation in the vegetable oil sampling process have affected the quality and storage safety of edible oil in my country.
