Izmeritel poristosti hleba

designed to determine the porosity of bread by the Zavyalov method

The device for measuring the porosity of bread crumbs BPM is designed to determine the porosity of bread by the method of Zavyalov (analog of the Zhuravlev device).

Scope: in the laboratories of flour mills, bakeries and other organizations, research institutions engaged in the evaluation of bread quality.

The device consists of a calibration cylinder, ejector, detachable glass and a knife. Allows a loaf of bread to be cut from a loaf of bread or loaf, and a porosity can be calculated by weighing the cut out. The device allows to carry out measurements with high enough accuracy, simple and convenient in operation, has sufficient reliability, does not require special training of the operator.

From the middle of the product cut a piece of crumb with a width of not less than 6.0 cm. the crumb. The cylinder-filled cylinder is placed on the glass guides. The bread crumb is then pushed out of the cylinder by an ejector into a cutting beaker. The crumb should come out of the cutting glass not less than 1 cm. Cut the crumb with a cutting knife reciprocating with a light pressure. The remaining crumb in the detachable glass is ejected by the ejector.

To determine the porosity of wheat bread, make three cylindrical notches, for rye bread and bread from a mixture of flour - four notches. In artificial products, where the slices are small, the clippings are made of two products.

Further, in accordance with the methodology and formulas described in the operating instructions to calculate the porosity.

The porosity is calculated to within 1%. Shares up to 0.5% inclusive are discarded and more are equated to 1.
