In this article we consider methods of inactivation of anti-nutrient substances of leguminous crops by means of preliminary treatment: melting and extrusion of grain. It has been found that the main anti-nutrient of legumes is a trypsin inhibitor. It is concluded that it is impossible to use leguminous crops as animal feed without preliminary treatment. We have considered issues of use of leguminous crops in feeding farm animals in the form of flour, cake, extraction cake, protein concentrates, milk, green mass, hay, senage, herbal flour and silage, and it has been established that the most promising direction of preparation of leguminous animals for feeding by agricultural animals is preparation of liquid protein suspension
The authors have developed classification tools for
grinding feeds and the most promising directions in the
development of tools for the grinding of forages in reducing
energy and metal consumption. We have described
chopper stem of feed, which provides high performance
and good quality of product. In the article,
there is an analysis of existing methods of grinding
coarse fodder and their classification. The work presents
examples of application of stationary and mobile
crushers for crushing of grain and roughage, the technical
parameters of the equipment for preparation of
feed for feeding
The article examines the existing technologies and facilities for the preparation of soybeans for feeding animals, and de-veloped a technological line of preparation of high-protein feed based on soybean. The design of a chopper for soaked soybeans, working on the proposed technology has been pre-sented
To increase the productivity of the cattle it is demanded
simultaneous distribution of all types of
animal feed in the form of balanced feed mixture
with a given nutritional value. Balanced feeding of
animals can improve their productivity, reduce feed
wastage, and include alternative components of
feed mixtures in their diets, which have nourishing
properties and high digestibility; make and adjust
feeding rations. Researches conducted by Russian
and foreign scientists, proved the prospects of full
feeding of complete feed mixtures, which allow to
increase the productivity of animals to 9-30 % and
reduce the feed consumption in the calculation of 1
с of milk by 7-8 %. The composition of complete
feed mixtures includes sunflower cake, silage, root
crops and forage. The process of preparation and
distribution of feeds for large horned livestock is
the issue of all the necessary components of the
feed mixture with a given nutritional value. Saturation
of the feed product with extra energy goes during
its interaction with the working bodies of technical
means for preparation and distribution
(TMPD) of different types of food. For preparation
and distribution of components of the feed mixture
it is necessary to have following facilities, provided
with reducing energy intensity and improving the
qualitative indicators of processes: for grinding beet
fodder and sunflower cake we need disk shredders;
for shredding silage and roughage – bearnie and
rotor shredders, respectively; for dispensing of beet
fodder and sunflower cake – belt conveyor, for dispensing
silage and roughage we use disc and drum
dispensers, respectively; for mixing sunflower cake
- rotary mixers, and for silage, beet fodder and for-age we may use paddle mixers; for distribution of
sunflower cake we use rotary feeders, for silage and
beet fodder – bin distributors, and for coarse feed
we should use conveyor dispensers
We have offered a constructive flow sheet of a root cleaner. Theoretical and experimental studies of roots purification process have been performed. We have also substantiated the main structural and regime pa-rameters of the proposed cleaner
Developed a technological line of preparation of high-protein feed based on soybean. The design chopper soaked soybeans, working on the proposed technology
In this article we consider the analysis of structures of technical means used for the preparation and distribution of animal feed and develop a distributor-chopper, which allows distributing it while milling. The classification is designed for feeders; we also give economic and mathematical model and a constructively technical scheme of a distributor-chopper on its basis
The authors have developed and manufactured a large
number of different designs of relative helical drums
for mixing animal feed. We have conducted 749 field
experiments with the drums of the 10 different designs
with different parameters modes of operation. In all
experiments, we measured the quality of the feed mixture.
However, directly based on empirical data, rational
choice of design features and parameters of the
operation modes of the reels is not possible. For this,
you must first develop a model reflecting these empirical
data. The construction of meaningful analytical
models of different types of drums is a difficult and
demanding scientific task, the complexity of which is
due to the large variety and complexity of forms of
drums and their mode of usage, a large number of diverse
physical factors affecting the processes in the
drum. As a consequence, the development of analytical
models associated with a large number of simplifying
assumptions that reduce their versatility and reliability.
Therefore, it is important to search of a mathematical
method and software tools provide a quick and simple
for the user to identify and influence the design of the
drum and the parameters of the operating modes on the
quality of the feed mixture directly on the basis of empirical
(experimental) data. The work proposes a solution
to this problem with the use of a new universal
innovative method of artificial intelligence: automated
system-cognitive analysis (ASC-analysis) and its programmatic
Toolkit – universal cognitive analytical
system called "Eidos". In the system of "Eidos" we have implemented a software interface that provides
direct input into the system large amounts of empirical
data from Excel file. Created on their basis in the system
of "Eidos" system-cognitive model allows the visual
form to reflect the effect of the structure of the
drum and the parameters of the operating modes on the
quality of the resulting feed mixture and to develop on
this basis the science-based and appropriate recommendations
for the rational choice of design features
and parameters of the modes relative to the screw
drums. We have also given a numerical example
We have presented an analysis of hardware designs for preparation and distribution of animal foods and also developed the economical and the mathematical model of the process of preparation and distribution of food. We have developed a constructive-technological scheme of distribution chopper and a theoretical justification of the parameters of the distribution chopper
An original design of a piston press, performing material pressing, due to case design tapered piston and the matrix, has been proposed for the first time
