MILK COOLING UNIT BASED ON THERMOELECTRIC MODULES

Abstract

The tendency to increase the consumption of personalized nutrition opens up new prospects for the industrial production of milk from an individual cow with preserved useful components inherent in a specific animal species, the composition of fat, protein, lactose, and taste. A milking installation is composed of robots for individual milking of cows with automatic control of milk quality indicators. At the same time, milk corresponding to the parameters of high quality enters the thermoelectric plate-type cooler - heater, then into the packing machine, where it is bottled into containers to further proceed to the refrigerator. Thermal modules as a cooling element are chosen due to their high speed and the ability to accurately control the set temperature. At the same time, water is heated through the hot heating system of the thermal module, which is used for the technological needs of the farm. The work aims at developing and justifying the parameters of an energy-saving thermoelectric system for cooling native individual milk from a cow and heating water in milking robots for the production of personalized food products. The authors present a technological line scheme with milk cooling directly during the milking process. Analytical relationships are given for calculating the parameters of a thermoelectric cooling system according to two options - the milk flow rate and the parameters of the cyclic supply of one-time equal portions of milk. The proposed technology and method for milk cooling in the flow using thermoelectric modules as part of milking robots makes it possible to develop a new technology for the production of high-quality dairy products according to individual orders of consumers.
