Abstract
The article reflects the process of dehydration of brewer pellets, as one of the ways to solve the problem of their utilization in order to obtain a highly concentrated feed for farm animals, which is an urgent task. The purpose of the study is to substantiate the interrelation between the technological and physical properties of the brewer pellets during the separation of brewer pellets into dense and liquid fractions in a continuous vibratory-centrifugal centrifuge and its main design and operating parameters. As a result of the research with the analytical method, process and physical properties of brewer pellets are determined when they are interacting with the perforated rotor blades of a vibratory-centrifugal centrifuge. The equations for the yield of the liquid fraction of brewer pellets through the rectilinear and curvilinear rotor blades are obtained, indicating the interrelation between process and physical properties of brewer pellets, which are necessary for determining the rational basic parameters of the proposed vibratory-centrifugal centrifuge.
Highlights
Increasing the productivity of animals and poultry is one of the main tasks of animal husbandry, which is implemented through the use of new types of feed and introduction of advanced resource-saving machines and technologies for their high-quality production
As can be seen in the scheme, the initial mass is first supplied to a straight blade with rectangular openings up to 2 mm high, on which the remaining particles of the most part of the dense fraction are retained and move to their ejection from the centrifuge in the direction towards the periphery of the rotor due to centrifugal forces, and the liquid fraction with the particles enter the surface of the curved blade and there is a final dehydration of brewer pellets
As a result of the research using the analytical method, the technological and physical properties of brewer pellets are determined when interacting with the perforated rotor blades of a vibratory-centrifugal centrifuge
Summary
Increasing the productivity of animals and poultry is one of the main tasks of animal husbandry, which is implemented through the use of new types of feed and introduction of advanced resource-saving machines and technologies for their high-quality production. This topic is relevant and is considered in many works [1, 2]. The problem of selling beer waste is very acute because of insufficient financial resources in agricultural enterprises. The topic of beer granules and everything connected with them is analysed in several works [6,7,8,9,10]
