The Study of Influence of the Process of Mechanical Additional Cleaning on the Surface Onion Layer at Combined Process of Cleaning

Abstract

The one of the ways of solving question of high-quality cleaning of vegetables is the use of combined methods of cleaning, their study and creation of equipment. The improvement of process for its realization and equipment support at trade enterprises, restaurant economy and mini-factories is a topical task. The expedience of elaboration and introduction of combined processes and equipment for their realization at institutions of the restaurant economy and vegetable-processing enterprises give a possibility to exclude the additional equipment for calibration, sorting, washing, additional cleaning. It, in its turn, will provide the safety at production, favoring the more rational use of resources. The one of most prospective directions of intensification of process of cleaning of the vegetable raw material is an elaboration of combined methods and new specialized apparatuses, which work principle is based on combination of the processes of cleaning of product. The experimental setting was elaborated with correspondent methodology that allows carry out the study of process of cleaning of onion with possible determination of influence of all its parameters on the percent of the raw material losses and effectiveness of product cleaning. It is provided due to the presence of work drum in experimental setting that rotates around its axis. The rotation frequency can be changed within the necessary diapason. The work drum has on its surface the special orifices for cutting off the inedible part of onion. The experimental setting also includes tensometric module that allows determine the effort of separation of peel from onion. The use of apparatus for cleaning of onion will give a possibility to intensify process, to improve the quality of cleaning, to decrease the percent of raw material losses.

Modeling of mechanical treatment of napiform onion to determine the rational parameters of its cleaning

“…Based on the above selected factors, which need to be explored, we devised a technique to examine the process. This technique of examining the process of vegetable raw materials mechanical treatment is presented in detail in paper [19]. For theoretical modeling of the process of mechanical cleaning of onion in the proposed drum-type device, we shall use general theory of drum mills.…”

Analysis and Modeling of the Onion Peeling Process in the Blowing Compressed Air Method

“…In their works, the authors mainly define the relationship between quality, effectiveness, process efficiency and raw material factors, such as the drum rotational speed, inclination angle, degree of filling, air pressure or the presence of water (including water at different temperatures), the size and shape of the onions, onion feed rate, etc. [33][34][35]. The latest solutions suggest cutting the onion peel and blowing it off with compressed air or water.…”
