Description

Vynález sa týká přenosného škrobomeru na meranie škrobnatosti zemiakov.The present invention relates to a portable starch meter for measuring starch potato.

Na velkosti mernej hmotnosti zemiakov sa v rozhodujúcej miere podiela obsah škrobu. Doteraz používané přístroje na meranie škrobnatosti zemiakov pracuj úce fyzikálnou metodou sú naložené na principe zisťovania objemu a mernej hmotnosti vzorky na základe Archimedovho zákona. Sú to napr. Reimannova váha, Parowa váha a Nýdrlová váha, ďalej Sajfertova váha na zisťovanie škrobnatosti jednej hl’uzy. Přepočet mernej hmotnosti na škrobnatosť sa uskutočnil pomocou tabuliek, a to tabulky Fothove, Maerckerove, Nýdrlove atď. V súčasnej praxi sa používajú obměny Hošpes—Pecoldovej váhy, s ktorou sa pracuje bez potřeby tabuliek.The starch content is a major contributor to the specific gravity of potatoes. So far, the instruments used to measure starch potency using the physical method are loaded on the principle of determining the volume and specific gravity of the sample according to Archimedes law. They are eg. Reimann's weight, Parowa's weight, and Ndrdrick's weight, and Sajfert's weight to detect starch starch. The conversion of the specific gravity to starch was carried out by means of tables, namely the Foth, Maercker, Ndrdr, etc. tables. In the current practice, variations of the Höpes-Pecold scale are used, which are handled without the need for tables.

Vyššie uvedené nedostatky odstraňuje přenosný škrobomer na meranie škrobnatosti zemiakov meraním objemu kvapaliný, například vody, vytlačenej zemiakmi, pozostávajúci zo zhora otvorenej nádoby, napr. válcovitého tvaru!, ktorá je vo vnútri predelená horným dnom na hornú plniacu časť a spodnú odmernú komárku, ktorého podstata vynálezu spočívá v tom, že v hornom dne je vsadená zvislá přepadová rúrka, siahajúca pod vrchný otvor nádoby a spájajúca plniacu časť s odmernou komórkou, opatřenou v spodnej éasli áolnym šikmým dnom. V najnižšéj Časti odmernej komórky je vsadený vypúšťací kohútik a v najvyššej časti je upevněná odmerná rúrka. Odmerná rúrka je vyvedená mimo nádobu a je vo svojej časti, siahajúcej na odmernú komórku, transparentná pre umožnenie sledovania výšky hladiny kvapaliný vytlačenej zemiakmi z plniacej časti. Přepadová rúrka je opatřená ostrým alebo zúženým okraj om pre zvýšenie citlivosti přístroj a. Transparentná časť odmernej rúrky móže byť zvislá alebo šikmá s konštantným kalibrovaným prierezom po celej dlžke alebo vo viacerých zúžených častiach a opatřená stupnicou pre priame odčítanie hodnoty škrobnatosti, ktorá je úměrná výške hladiny kvapaliny vytlačenej zemiakmi.The abovementioned drawbacks are overcome by a portable starch for measuring the starch potency of potatoes by measuring the volume of liquid, e.g. cylindrical shape, which is internally divided by an upper bottom into an upper filling part and a lower measuring cup, the essence of the invention is that a vertical overflow pipe extending below the upper opening of the container and connecting the filling part to the measuring chamber is inserted in the upper bottom; provided with an inclined bottom in the lower part. In the lowest part of the measuring chamber a drain cock is inserted and in the upper part a measuring tube is fixed. The metering tube is led out of the container and is transparent in its portion extending onto the metering chamber to allow monitoring of the level of liquid displaced by the potatoes from the filling portion. The overflow pipe is provided with a sharp or tapered edge to increase the sensitivity of the apparatus. The transparent portion of the measuring tube may be vertical or oblique, with a constant calibrated cross-section over the entire length or in several narrowed portions and provided with a scale for direct reading of the starch value, which is proportional to the level of liquid displaced by the potatoes.
