Abstract
The invention discloses a method for testing the cleaning rate of a fruit and vegetable cleaning machine. The method comprises the following steps: 1), utilizing a platform scale to weigh 500g of fruit and vegetable samples cleaned by the fruit and vegetable cleaning machine, utilizing a counting cup to obtain 500ml of drinking water, adding the drinking water into the counting cup, washing the fruit and vegetable samples by hands for 2 minutes and fishing out the fruit and vegetable samples; 2), weighing the mass of qualitative filter paper, then utilizing the qualitative filter paper to filtering the water used for cleaning the fruit and vegetable samples, and drying the qualitative filter paper into a 1.5W electrically heated drying cabinet after filtering; and 3), weighting the mass of the dried qualitative filter paper; and 4), calculating the cleaning rate of the fruit and vegetable cleaning machine, wherein the cleaning rate=(the mass of the dried qualitative filter paper-the mass of the qualitative filter paper before being filtered)/500g. The method disclosed by the invention has the following beneficial effects: the mass difference between the dried qualitative filter paper and the qualitative filter paper before being filtered is calculated, and then mass difference is divided by the mass of cleaned fruits and vegetables, so that the cleaning rate of the fruit and vegetable cleaning machine can be obtained, thus the performance of the fruit and vegetable cleaning machine can be quantitatively evaluated.
Description
Technical field
The present invention relates to a kind of fruit-vegetable cleaner, particularly a kind of fruit-vegetable cleaner is cleaned the method for inspection of rate.
Background technology
Fruit-vegetable cleaner is to be used for cleaning melon and fruit, vegetables machinery and equipment specially, though hairiness brush washer, bubble type cleaning machine already on the market never in order to check the method for inspection of this series products, not have the national standard and the company standard of being correlated with yet.
Summary of the invention
The problem that the present invention will solve is: the method for inspection that a kind of clean rate of fruit-vegetable cleaner of quantification is provided.
In order to solve the problems of the technologies described above, fruit-vegetable cleaner of the present invention is cleaned the method for inspection of rate, comprises the steps:
The first step takes by weighing the fruits and vegetables sample 500g after fruit-vegetable cleaner cleans with platform balance, measures the 500ml potable water with measuring cup and adds nappy, and hand washing fruits and vegetables sample 2 minutes is pulled the fruits and vegetables sample out;
Second step; With the quality of photoelectric analysis balance weighing qualitative filter paper, and, filter with this qualitative filter paper then and clean the used water of fruits and vegetables sample this quality record; After filtering completion; Qualitative filter paper is put into the 1.5kW electrically heated drying cabinet, and keeping the temperature of electrically heated drying cabinet is 100 ℃, and be 20 minutes drying time;
The 3rd step, will take out through the qualitative filter paper of drying, the quality of the dried qualitative filter paper of photoelectric analytical balance weighing, and with this quality record;
In the 4th step, the clean rate of calculating fruit-vegetable cleaner is cleaned rate=(quality of qualitative filter paper before the quality-filtration of dry back qualitative filter paper)/500g.
In order to improve the filtration efficiency of qualitative filter paper, fruit-vegetable cleaner of the present invention is cleaned the method for inspection of rate, and said qualitative filter paper is the middling speed qualitative filter paper, and its diameter is 102-105mm.
In order to improve measuring accuracy, fruit-vegetable cleaner of the present invention is cleaned the method for inspection of rate, and the precision that said photoelectric analytical balance is claimed is 0.01mg.
The beneficial effect that the present invention obtains is: filter the back qualitative filter paper and filter the of poor quality of preceding qualitative filter paper through measurement, divided by the quality of the fruits and vegetables that are cleaned, obtain the clean rate of fruit-vegetable cleaner, thereby quantitative evaluation and test goes out the performance of fruit-vegetable cleaner.
