Description
Technical field:
The utility model relates to a kind of extraction and cleaning device more particularly to a kind of devices for vitamin extraction and cleaning.
Background technique:
Vitamin is one kind active material essential to maintaining human body and animal body normal physiological function, is sent out in body growth
Educate, metabolism etc. plays an important role, body itself can not synthesize, and can only be absorbed by food chain, most
Agricultural product and forage grass in rich in there is vitamin, water soluble vitamin can be divided into according to its dissolution characteristics and fat-soluble dimension is given birth to
Element.
Water soluble vitamin mentions that method is relatively inefficient, and extraction process is more many and diverse at present, and big multi-method is a kind of
Method can only extract a kind of parameter or the similar parameter of certain several special properties, the method for rarely having many kinds of parameters while extracting, and
And chromatographic technique is qualitatively and quantitatively leaned on when detecting mostly, extractant mainly has 1%H3PO3, 0.1mol/L acetic acid etc.；For example, GB
5413.14-2010 in vitamin B12It is extracted when extraction using microbial method, GB5009.84-2016 is mentioned in vitamin B1
When taking, first with 0.1mol/L hydrochloric acid in 120 DEG C of hydrolysis 30min, be cooled to room temperature after hydrolysis, hydrolyzate need to through enzymatic hydrolysis 16h,
Finally need to purify, aoxidize etc. the extraction that processes are just able to achieve vitamin B1 in sample；The effective national standard of present or document
Extracting mode in report about liposoluble vitamin is equally comparatively laborious, most extractive technique use saponification means, such as
When extracting vitamin A and E, extraction process is that the mixing of addition sample and dehydrated alcohol and potassium hydroxide in conical flask is molten
Liquid is protected from light concussion 30min in 80 DEG C of water-bath and is saponified, then that solution is cooling and be transferred in separatory funnel, connects
The Extraction solvents such as addition petroleum ether, ether extracted, finally wash ether layer repeatedly with water to neutrality, ether layer is through drying, dense
Contracting and etc. be finally completed extractions, Extraction solvent is inflammable, the high toxicity organic reagents such as petroleum ether, ether, is harmful to the human body；Together
When lack purification techniques during the extraction process, easily cause detection device pollution, reduce sensitivity the problems such as.
Utility model content:
The purpose of this utility model is to provide a kind of structure is simple, extraction process is simple, and one with clean-up effect
Kind is used for the device of vitamin extraction and cleaning.
The utility model is implemented by following technical solution: a kind of device for vitamin extraction and cleaning comprising one end
Closing, cylinder, short tube, piston head, piston rod, piston handle and the handle of setting open at one end；Connect in the closed end of the cylinder
It is logical to be fixed with the short tube, filter membrane is provided in the short tube；The handle is fixed in the open end of the cylinder；?
The inner cavity of the cylinder is disposed with packing layer and the piston head from closed end to open end；One end of the piston rod from
The cartridge openings end is inserted into and is fixedly connected with the piston head, the other end of the piston rod and the fixed company of the piston handle
It connects；The center line of the cylinder, the short tube and the piston rod is straight line.
Further, inlet tube is provided on the side wall of the cylinder, one end connection of the inlet tube is fixed on institute
It states on cylinder；The other end of the inlet tube is covered with lid.
Further, described filler layer is made of silica gel and neutral alumina.
Further, the filter membrane is made of polyvinyl chloride, and aperture is 0.22 μm.
Further, it is 5cm, internal diameter 4.5cm, the cylindrical shape of a length of 15cm that the cylinder, which is outer diameter,.
Further, the internal diameter of the short tube is 3cm.
The advantages of the utility model: the utility model structure is simple, Yi Shixian；When detecting, it is only necessary to by sample and mention
It takes solvent to be added in cylinder, then will extract sample again and be injected into sample bottle, extraction process is simple and convenient, time saving and energy saving；Together
When the closed end of cylinder is provided with packing layer, effectively realize the purification during the extraction process to sample is extracted；It ensure that
The detection device in later period will not be polluted, in turn result in the reduction of detection sensitivity, testing result is effectively guaranteed
Accuracy；Using the utility model to sample carry out vitamin extraction, the Extraction solvent used be changed to water, isopropanol and just oneself
Alkane avoids appearance danger, guarantee it is not necessary that petroleum ether, ether etc. be inflammable, high toxicity organic reagent is as Extraction solvent use
Human health.
Detailed description of the invention:
Fig. 1 is the overall structure diagram of the utility model embodiment.
Cylinder 1, short tube 2, piston head 3, piston rod 4, piston handle 5, handle 6, filter membrane 7, packing layer 8, inlet tube 9, lid
Body 10.
Specific embodiment:
Below in conjunction with attached drawing, by embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of device for vitamin extraction and cleaning comprising it is closed at one end, setting open at one end
