GMO bio-safety detection technique standard of set etc. is put into effect in succession.Inspection mechanism professional and technical personnel is carried out to sample
During detection, solid sample such as wheat, corn, paddy rice etc. are ground firstly the need of to it, the standard grinds quantity to sample
(during detection limit 0.5%, sample size is 600；When detection limit 0.01%, sample size is 30 000；And each sample will
Meet the Single seed weight requirement that standard specifies), particle diameter (<2mm) etc. clearly require.This is accomplished by detecting that what is used grinds
Grinder should meet the volume requirement of sample, also meet the requirement for grinding sample particle diameter.
The species such as the existing mill of in the market, broken instrument are various, such as the high-flux tissue being commonly used in testing grinds
Grinder and the broken instrument of middle flux tissue grinder etc. can be ground to multiple samples simultaneously in a short time, substantially solve
The requirement of plant, animal tissue, food, medicine, ecological environment material nd to sample, but this mill detection sample used
Some problems are there is also in journey：(1) single container storing samples quantity can not meet detection sample size to container sometimes
Demand, if being ground the probability that will certainly increase sample contamination using different containers by several times, while to follow-up sampling
Weigh etc. and to cause trouble.(2) this mill generally uses steel ball etc. and is shaken and sample by the way that mill is reciprocal at a high speed as medium
Product produce friction so as to reach the purpose of attrition grinding sample, and cryogrinding under liquid nitrogen is needed in many cases, and sample is at a high speed
When container after concussion grinding together with grind away is removed, if because container inner pressure is opened higher than the pressure in container external environment
The too quickly or container cover of lid does not cover tightly fully and is easy for causing sample to spray in fact, makes the substandard requirement of sample size, from
And cause the detection operation termination of sample, cause economic loss to client and testing agency.
In addition, family expenses and medical small-sized plainly-packed mill in the market, although disclosure satisfy that solid detects sample
The need for grinding, but weak point is still present：This mill typically using vertical movement by the way of, so fuselage is generally
Vertical structure, crank is easily caused, it is necessary to external force assists to ensure that its normal safe runs in process of lapping；At present,
Also there is the appearance of horizontal movement mill, though this mill solves the problems, such as crank, this mill is once only
Single sample can be ground, when detecting that the disposable quantity of sample is more, just be lost time very much using this mill,
Also waste of manpower and material resources simultaneously.The service quality of testing agency in order to better improve, efficiently, it is accurate, quick, guarantee both quality and quantity
The sample detection task that is provided of completion client it is extremely important for testing agency.Therefore, in order to better meet detection
The demand ground with solid sample, is badly in need of a kind of new mill to solve the problems, such as to be run into grinding.
