AB  - Ultrasonics is new science that is being intensively developed in recent 
years. Sound velocity is a valuable engineering tool and non-destructive, non-invasive, 
non-intrusive technique of measurement. The various effects of ultrasound were 
discussed and outlined in a context of different uses to accelerate or support 
agricultural production processes like: vibrational and heating effects, cavitational 
effects, speeding up biochemical processes, mutagenic effects, etc. Special attention 
was paid on crystallization and separation processes in operational engineering. This 
paper presents a review of ultrasonic wave application in agricultural production and 
modern agricultural systems.

AB  - This study deals with the manufacturing process of compost production, followed by the release of large amounts of heat. The wheat straw and manure of broilers were the basic components of the raw mixture, monitored during the 80 h period. The simplified assessment method was developed along with suitable mathematical model. The potential for recovery of the heat released to the surroundings was evaluated indirectly based on compost temperature measurements during the one full production cycle. Temperature- time mathematical model was developed and used as time indicator for the analysis of distribution of energy that was generated in exothermic processes. The emissions of N ( lt  1% dry basis) and C through CO2 (similar to 3% dry basis) was neglected in mass balances. During composting treatment material temperatures were in range 80 +/- 2 degrees C, making it a reliable heat source of constant temperature. The amount of total generated heat during the 80 h time period was calculated to be 1325 kJ center dot 10(6), of which 76.4% was released to surroundings. The specific value of generated heat was 1.32 kJ g(-1) of raw mixture, of which 1.01 kJ g(-1) was available for recovery. The results pointed to the existence of significant amounts of released energy available for recovering.

AB  - Natural liquid manure as a suspension of overall cow and related categories excreta, 
with out of admixtures of bedding matherials and residues of anused feed, is diversified 
energetic source, because it can produce gas, heat, electric power, fuel, etc. Teh introduc tion of natural liquid manure in treatment towards energy production, contribute not only 
to energy efficency of farm, but also to better envirnoment protection because of increased 
emission of sulfur dioxide, carbon dioxide and nitrogen dioxide, compared to combusti on of fossil fuels. In addition, a significant ammount of pathogens are destroyed and 
weeds seeds that can be found in manure germination energy is significantly lower.
This paper presents optimal technology and technical solutions of liquid manure 
usage for improving energy efficiency of small farms, and also the folloving total usa ge of liquid manure as organic fertilizer. In this paper, a mini farm of 50 dairy cows, 
which are now common i Serbia has been considered. Methods of collecting, proce ssing, preparation, and use of liquid manure, in our conditions are not met at a wider 
application, due to the extensive production. 
Huge ammounts of this organic fertilizer with graet nutritive potential in forms that 
are easily accessible to plants are not used in any way, and are uncontrollably released 
to envirnoment cousing pollution to envirnoment in any possible way. That practise 
must be stopped.
Economic effects in countries with less developed livestock production, such as 
ours, suggest that this issue must be given adequate attention and redirected the way of 
production, which, with secondary products can significantly improve the outcome. 
This paper gives direction to it.

AB  - Contemporary, farm oriented, milk production involves obtaining of highly valuable, hygienically safe 
product. At the same time, farmers are under constant pressure to find new ways to reduce production 
costs. One of the most important factor in the total structure of costs are costs of energy. This paper 
presents the analysis of possibilities and effectiveness of usage of the system for recovering heat 
obtained by milk cooling process. The system consists of a heat pump " milk - water ", plate type pre -
cooler with counter flow of water and milk and storage vessel. The heat obtained from milk cooling 
process, is used to heat water instead of being wasted to the environment. Warm water is required on 
the farm for many reasons. Significant energy savings can be made by using this system. Experimental 
investigation was carried out on the family farm, where the milking was performed twice a day. After 
each milking, milking equipment is washed with warm water. The results showed that the application 
of this system can realize significant cost savings, as well as the potential of improving the efficiency 
of individual components of the system.

AB  - The analysis of producing of heat from the compost production process, with goal 
to determine a rough sketch of the potential use of heat that develops in the process of 
composting is presented in this paper. Production of compost from solid cattle manure 
in bright plateau, using appropriate equipment is considered. Conductet temperature 
measurments revealed the temperature increase in the mass of up to 75 ° C,with a fairly stable temperature regime. A model for the analysis, elemental prism was adopted. In 
the conducted analysis, certain approximations and simplifications were adopted. This 
is done because of that in this step only a rough estimate of the potential of heat pro duction is expected. Results from the analysis show that the observed process deserves 
a more detailed approach, both in experimental work and in completing the analysis of 
the factors that influence this process.

AB  - Contemporary livestock production implies production of highly valuable, biologically and chemically safe products. Dairy pro duction has no exception too. On the contrary, the quality standards for raw milk are highly increased. The quality of raw milk is de fined by its chemical composition and the total count of microorganisms in control volume. In this paper we discussed the perform ance of advanced system for heat recovery from raw milk and its application in the process of preheating and preparation of process 
water. The energy and exergy efficiency of one of such systems were analyzed. It was determined that the implementation of the sys tem for milk cooling with precooling and using the waste heat for preheating process water could achieve significant savings. The 
system consists of "milk to water" heat pump, pre-cooler for milk cooling and storage tank for process water with heating possibility.
Values of exergy efficiency of each component of system and potential improving of components performances were determined. Also, 
the exergy efficiency and potential improvement of complete system were determined

AB  - The paper presents results of an energy and exergy analysis of a diary refrigeration heat recovery system performance. The heat recovery process involves the transfer of “waste” heat from the refrigerant of the milk cooling system into water. The input data for this analysis (refrigerant, milk and water parameters: mass flow, pressure and temperature at relevant system points) was collected on similar dairy farm heat recovery system. This information was used to describe the initial and boundary conditions in a study on the evaluation of energy utilization efficiency. Exergy analysis has provided different indicators of energy quality. Also, exergy analysis has helped detecting loss and destruction of incoming exergy for the productive process. It was concluded that integration of heat recovery unit in a complex diary process, in combination with other specific devices, must be conducted carefully, in order to obtain its maximum capacity and performance.
