Embodiment 2

[0059] The processing method for detecting the content of methylene methanol in soybean louvers by using the above-mentioned food sample pretreatment instrument includes the following steps:

[0060] Step 1: Add 1 g of soybean louver and 10 g of water into each centrifuge tube 34 .

[0061] The second step: the first lifting motor 1 is controlled by PLC to start, the first lifting motor 1 drives the first screw rod 3 to go down, and the first screw rod 3 drives the upper moving plate 22 through the servo motor cover horizontal plate 5 and support column 6 A guide column 17 moves up and down, makes the servomotor 7, stirring motor 14 and the stirring rod 30 in the multi-stage transmission mechanism installed on the moving plate move downward, until the stirring rod 30 stretches into the centrifuge tube 34 and mixes with water and The jellyfish wire contacts, and then the first lifting motor 1 is controlled by PLC to close.

[0062] The third step: the PLC controls the stirring...

Abstract

The invention relates to a food sample preprocessing instrument for food safety testing and a processing method thereof. The food sample preprocessing instrument comprises lifting motors, guide mechanisms, a multistage drive unit, a servo motor, a stirring motor, stirring rods, a blade and a heating trough. The multistage drive unit, the servo motor, the stirring motor, the stirring rods and the blade effectively and automatically extend into or out of centrifugal tubes by arranging the first lifting motor and the first guide mechanism, automatic ascending and descending of the heating trough are achieved by arranging the second lifting motor and the second guide mechanism, vertical movements of the units are more precise by arranging the first guide mechanism and the second guide mechanism, the stirring rods and the blade rapidly stir and smash the raw material in the centrifugal tubes through the stirring motor and the multistage drive unit, and the centrifugal tubes do not easily disengage from a rotating disc during centrifugation by arranging supporting blocks and centrifugal tube sleeves. The liquid in the centrifugal tubes is not easily splashed during centrifugation by arranging rod sleeves. The food sample preprocessing instrument replaces an existing manual operation method, the human resource cost is saved, and the testing and processing requirements are met.

Description

technical field [0001] The invention relates to the field of food testing, in particular to a food sample pretreatment instrument and a processing method for food safety testing. Background technique [0002] Food safety testing is to detect illegally added harmful substances in food in accordance with national indicators, such as formaldehyde, hangover, pesticides, etc. Existing food testing and processing are all through manual extraction, which is cumbersome and cumbersome. It is time-consuming and labor-intensive, greatly increasing the cost of human resources input, and the penetration rate is low. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has carried out research and improvement, and provides a food sample pretreatment instrument and processing method for food safety testing, which can quickly and effectively extract harmful substances illegally added in food, and has a relatively high degree of automation. Hi...
