Abstract
The utility model relates to a digestive system for a crude protein determining method, which belongs to the technical field of grain and oil, products of the grain and oil and the feed industries and overcomes defects of unreasonable fixing of a Kjeldahl flask during the digestive process in the prior art. The digestive system mainly comprises three stacked fireproof bricks, an electric stove and the Kjeldahl flask, wherein through holes are arranged in the middle of the fireproof bricks. The stacked fireproof bricks are arranged on the electric stove, the Kjeldahl flask is slantingly arranged in the through holes of the fireproof bricks, and a small funnel is arranged at the position of a bottle opening of the Kjeldahl flask A.
Description
Technical field
The utility model relates to a kind of digestive system of crude protein assay method, and it belongs to grain and oil and goods and feed industry technical field.
Background technology
The mensuration of national standard crude protein comprises digestion process and still-process.In digestion process, often adopt extension clamp to clamp kjeldahl flask and heat, four pawls of this extension clamp have plenty of with gum cover and entangle, and when heating, the phenomenon that gum cover burns can occur in this case; Have also that gum cover is embedded in four pawls is inboard, need remove during digestion, install again after in this case will occur gum cover loosening, can't reusable phenomenon.
The utility model content
The utility model is to deficiency of the prior art, and a kind of digestive system of rational in infrastructure, easy to operate crude protein assay method is provided.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of digestive system of crude protein assay method; Comprise that the centre that stacks has the refractory brick of through hole, electric furnace and kjeldahl flask; The said refractory brick that stacks is positioned on the electric furnace, and said kjeldahl flask tilts to be positioned in the through hole of refractory brick, and the bottle mouth position of said kjeldahl flask is placed with little funnel.
Compared with prior art; The beneficial effect of the utility model is: replace extension clamp with the refractory brick that stacks; Avoided extension clamp to cross cause thermal damage, got off to cause the concentrated sulphuric acid and hydrogen peroxide to spill the injury that causes human body thereby avoid kjeldahl flask to tumble with loosening; Make and place reliable, safety, make heat concentrate simultaneously and be difficult for diffusion; The bottleneck of kjeldahl flask leans against on the refractory brick; Added heat also for simultaneously the position near bottleneck, make that steam quickens to evaporate into top bottle wall, condensation has flow to bottle wall place, bottom then; Be flushed to the bottom of kjeldahl flask to the digestive juice of being stained with this position, be beneficial to concentrate digestion; When digestive juice is stained with on the bottleneck,, just can arbitrarily rotate kjeldahl flask, and nimbly and freely, danger drops to minimum as long as use crucible tongs.。
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said refractory brick is three and stacks.
Adopt the beneficial effect of above-mentioned further scheme to be: three blocks of refractory brick stack, and can guarantee that kjeldahl flask is placed with the angle of surface level to be a bit larger tham 45 degree, make in the bottleneck that is placed in kjeldahl flask that little funnel can be reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Electric furnace in the drawings, 1; 2, refractory brick; 3, kjeldahl flask; 4, little funnel.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of digestive system of crude protein assay method; Comprise that three centres that stack have the refractory brick 2 of through hole, electric furnace 1 and kjeldahl flask 3; The said refractory brick that stacks 2 is positioned on the electric furnace 1; Said kjeldahl flask 3 tilts to be positioned in the through hole of refractory brick 2, and the bottle mouth position of said kjeldahl flask 3 is placed with little funnel 4.
During work, at first the soybean seed is digested, be about to an amount of soybean seed and be positioned in the kjeldahl flask first 3, add suitable digestion solvent then, kjeldahl flask first 3 is placed on refractory brick 2 inside that are positioned on the electric furnace first 1 heats, obtain digestive juice at last, cooling; The digestive juice dilution that cooling is good is also transferred in the volumetric flask of regulation.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (2)
