STUDY OF THE PROCESS OF CHANGING WORKING FLUID TEMPERATURE IN A DIPPING VAT FOR SHEEP
The study results for dipping sheep in a dipping vat show that they do not provide sufficient quality treatment due to the incomplete penetration of the emulsion to the skin, as the animals are in the vat without movement. It was found that for complete saturation of the wool-skin cover of sheep submerged in the working emulsion, 60 seconds would be required when dipping. This is due to the fact that in the process of movement of the sheep in the liquid, the folds of the fur and skin cover occasionally move apart allowing the liquid to flow to the fatty layer. It has been found that the preventive effectiveness of dipping sheep is achieved with a stable concentration of acaricidal substances in the working emulsion, as well as full and uniform saturation of the sheep wool-skin cover with an emulsion. Dipping sheep in dipping vats provides reliable prevention of the disease while observing the necessary concentration of acaricidal substances in the working emulsion. The dipping exposure should be within 30-60 seconds, and the temperature of the working emulsion should be 18-20°C. However, stable maintenance of the temperature of the working fluid of the dipping vat is a very labor-intensive work. Therefore, the study of changes in the temperature of the working fluid in a dipping vat for dipping sheep is an important task. As a result of the study, mathematical dependences were obtained to determine the change in the temperature of the working fluid in the dipping vat depending on the number of sheep. In addition, a time range was determined in which the permissible value of the temperature of the working fluid in the dipping vat is reached. The results of the study showed that with an increase in the volume of liquid in the dipping vat the temperature increase slows down. The increase in the temperature of the working fluid is affected by the number of sheep in the dipping vat.
