An algorithm for determination of threshold value in extruded products by the method of maximum increments: modi􀂿 cation of Otsu method. There are presented the results of comparative analysis of threshold value determination in the extruded products with the use of developed new algorithm. The original and modi􀂿 ed Otsu algorithms were compared. In calculations of porosity indices of the extrudate cross section, the threshold values determined automatically with the use of investigated algorithms were compared with indications of an experts’ panel. The results of threshold value calculated with the use of the proposed algorithm were closer to values indicated by the expert panel, than that obtained with the use of comparative algorithms. However, the proposed method tends to overstate the threshold value; in some cases it can cause losing the pores of small lacunarity on the bit map calculated by this method.

W pracy podjęto badania oporów przepływu powietrza przez warstwę nasion buraka. Opory przepływu powietrza przez porowatą warstwę nasion, dla szerokiego zakresu wartości liczby Reynoldsa, opisuje zmodyfikowane równanie Leva. Wyznaczenie współczynnika oporów w zależności od liczby Reynoldsa pozwoli na zaprojektowanie wysokości warstwy w suszarce dla danego wentylatora lub dobrania wentylatora dla założonej wysokości złoża zapewniającego optymalny czas suszenia. Wyznaczono właściwości fizyczne nasion buraka ćwikłowego. Ustalono spadki ciśnienia na poszczególnych wysokościach złoża, co posłużyło do wyznaczana jednostkowego spadku ciśnienia. Zależność jednostkowego spadku ciśnienia i prędkości przepływu powietrza przedstawiono równaniem Erguna. Do opisu zależności między współczynnikiem oporów a liczbą Reynoldsa obliczono stałą K2= 15,03, charakteryzującą nasiona buraka.

The helium, apparent, and bulk densities were determined for ten types of starch. On the hasis of the results obtained, the porosity and volume of opened pores in starch granules and starch beds were calculated. The highest values for porosity and total volume of opened pores were characteristic of oat and tapioca starches, whereas triticale, rye and potato starches had these values the lowest. In the case of wheat and potato starches, the porosity of the closed type was shown.

The aim of this research was to analyze mechanical and acoustic properties of apples which were dried using different methods. Apple slices were dried using the following methods: convective, fluidal, microwave-convective and the sublimation. The obtained dried apple material was compressed in a Zwick machine with a velocity of 20 mm/min and with a simultaneous recording of the acoustic emission (AE) generated during sample destruction. Bruel&Kjsr accelerometer type 4381 was used for sound recording. Dried fruit porosity was also determined. Analyses conducted proved that drying methods significantly influence mechanical and acoustic properties of dried apples. Mechanical parameters: apparent Young's modulus, work and compression force were the highest for the fluidal dried apples, and the lowest for apples dried by the sublimation method. The latter group of dried apples was also most porous in structure. The obtained dried apple material differed in the number of events, the acoustic energy and in the range of emitted frequencies. There were negative correlations between mechanical and acoustic parameters of dried apples. The porosity of material correlated with the compression force, as well as the acoustic energy and the number of events.
