Influence of the design parameters of the peeling machine on the criteria of the peeling process effectiveness

Abstract

Technological efficiency of the peeling process, from the point of view of the number of detachable shells and unit costs for the process, is analyzed in the article. To assess the technological efficiency of wheat grain peeling, a generalized criterion of efficiency is proposed, which includes local criteria.Their dependence on the intensity of the grain processing in the machine is experimentally clarified. The experiments showed that the technological feasibility of the peeling process is ensured with the percentage of damper opening at the machine exit of δ3 = 60-70%, while the value of Cp.w. is 3.2-2.8%, ΔAc = 0.32-0.2%, and ΔB does not exceed 0.85%.

Physicochemical and Technological Evaluation of some Egyptian Hull-less and Hulled Barley Varieties for Biscuit Preparation

“…The moisten grains were immediately milled using an electric laboratory hammer mill (Perten laboratory mill 3100) having a sieve passage of 0.80 mm, then sifted through 60 mesh screens to obtain fine whole barley flour. The hulled barley grains (Giza 132,133,134,137,138) were firstly subjected to dehulling (peeling) using a peeling machine (Peeling machine-ЗШН) as reported by Anisimov et al (2022). The technique is based on the exposure of the grains to a highfrequency field while increasing the strength of this field during the peeling process to a certain maximum value, which leads to the separation of husks from the kernels while maintaining their quality.…”
