(108) output end of internal controller and weighing sensor (214) and the input terminal of AVR central control processor (109) are electrical
Connection, the output end and display screen (105), printer (104), the first stepper motor of the AVR central control processor (109)
(203) it is electrically connected with the input terminal of second stepper motor (210).
7. a kind of food content of beary metal device for fast detecting according to claim 1, which is characterized in that the sampler barrel
(206) outer diameter of internal diameter and pushing block (212) is transition fit.
8. a kind of food content of beary metal device for fast detecting according to claim 1, which is characterized in that the barb
(213) section is that arrow swears shape.
9. a kind of food content of beary metal device for fast detecting according to claim 1, which is characterized in that a food huge sum of money
Belong to the specifically used operating procedure of content device for fast detecting are as follows:
Step 1: then proportion buffer, enzyme powder, color developing agent and substrate will sample disintegrating mechanism (200) from inspection body
(100) it is taken out inside fixed groove (106)；
Step 2: will need the food sampled to be placed on specified work top, central to AVR by operational and controlled key button (108)
Control processor (109) sends instruction, is rotated by AVR central control processor (109) control the first stepper motor (203),
First stepper motor (203) passes through the outer gear ring (2052) of gear (204) and transmission ring (205) outer wall during rotation
Be engaged, so that transmission ring (205) be driven to rotate, the transmission ring (205) of rotation by the internal screw thread (2051) of its inner wall with
The imperfect external screw thread (2061) of sampler barrel (206) outer wall is screwed, so that sampler barrel (206) be driven to carry out movement, is made
The sample quality that can be collected between the top and pushing block (212) of sampler barrel (206) is obtained close to sampling definite quality, is then held
The food that the front end alignment of cut ring (207) is needed to sample by the lower support tube (202) of sample disintegrating mechanism (200) is captured, then
It is pierced into food, food can be split after being pierced by cut ring (207), after entering sampler barrel (206), pass through barb
(213) it prevents food to be detached from out of sampler barrel (206), sampling disintegrating mechanism (200) is then passed through into pedestal (201) and is placed on water
Flat desktop is transferred to AVR central control processor (109) by the weight data that weighing sensor (214) will test later, it
AVR central control processor (109) feeds back weight data by display screen (105) afterwards, later according to Weight gap tune
It saves the first stepper motor (203) and changes difference in height between the top and pushing block (212) of sampler barrel (206), then again by cutting
It cuts ring (207) and carries out cutting sampling, until sampling weight as defined in meeting；
Step 3: pouring into the buffer of prescribed volume inside sample bottle, then will sample the sampler barrel of disintegrating mechanism (200)
(206) it is inserted into inside sample bottle, is then sent and instructed to AVR central control processor (109) by operational and controlled key button (108),
Pass through AVR central control processor (109) control the first stepper motor (203) and second stepper motor (210) rotation, the first step
Into motor (203) during rotation, it is nibbled by gear (204) and the outer gear ring (2052) of transmission ring (205) outer wall
It closes, so that transmission ring (205) be driven to rotate, the transmission ring (205) of rotation passes through the internal screw thread (2051) and sampler barrel of its inner wall
(206) the imperfect external screw thread (2061) of outer wall is screwed, so that sampler barrel (206) be driven to carry out lower movement, is gradually reduced
The distance between top and pushing block (212) of sampler barrel (206), so that the food of sampler barrel (206) inside is made in pushing block (212)
Under, it is discharged from sampler barrel (206) is internal, and second stepper motor (210) passes through inserted link (211) band during rotation
Dynamic barb (213) high speed rotation, such food is during discharging, in the crowded of cutting sheet (2071) and barb (213)
Under pressure effect, realizes and crush, while the liquid in sample bottle is stirred by high-speed rotating barb (213), to solution left standstill
Afterwards, take supernatant liquor as sample liquid；
Step 4: taking two test tubes of A and B, pour into the buffer and sample liquid of prescribed volume to A and B test tube interior respectively, to
A, two test tubes of B are added the enzyme solution of prescribed volumes and color developing agent and stand one end time, are separately added into rule to A, B test tube again later
Determine the substrate of volume, the liquid in A, B test tube is taken to be poured into C, D cuvette respectively later, C cuvette is then put into detection cell
(101) control pond, D cuvette are put into detection cell (101) sample cell, by key (108) to AVR central control processor
(109) it sends instruction to be detected, wait for a period of time later, testing result can be shown on display screen (105), then be controlled
Printer (104) prints testing result.
