Milking and milk-storing system with waste-heat recovery and washing water sorted-collection functions

Abstract

The invention discloses a milking and milk-storing system with waste-heat recovery and washing water sorted-collection functions. The system comprises a milking machine end, a primary cooling heat exchanger, a milk storage tank, a cooling water tank, a cooling system with a waste-heat recovery function, a hot-water supply tank, an acid-liquid supply tank, an alkali-liquid supply tank, an acid-liquid collection tank, an alkali-liquid collection tank and a hot-water collection tank; a milk outlet pipeline of the milking machine end passes through the primary cooling heat exchanger to the milk storage tank; and the hot-water supply tank, the acid-liquid supply tank and the alkali-liquid supply tank are connected to the milking machine end and the milk storage tank through a washing pipeline,a washing liquid outlet of the milk storage tank is connected with the acid-liquid collection tank, the alkali-liquid collection tank and the hot-water collection tank through a pipeline, and the acid-liquid collection tank and the alkali-liquid collection tank are connected to the washing pipeline through a pipeline. The system disclosed by the invention can realize recycling of acid and the alkali liquids; and the cooling system with the waste-heat recovery function is adopted, heat in milk can be finally moved to effluent of a condenser, and the heat is stored into a waste-heat recovery storage tank, so that thermal resources are saved.

Description

technical field [0001] The invention belongs to the technical field of milking facilities, and in particular relates to a milking and storage system with functions of recovering waste heat and sorting and collecting flushing water. Background technique [0002] Milk storage systems typically include milking and milk storage facilities, as well as cooling and flushing systems. [0003] The function of the cooling system is to cool down the milk, so that the milk is stored in a low-temperature environment, thereby ensuring the preservation effect of the milk. The temperature of the freshly squeezed milk is generally about 37 degrees, and the milk is finally stored at about 4 degrees through the cooling system. The cooling system consumes a lot of energy and generates a lot of heat exchange. However, traditional milk storage facilities The advanced cooling system does not effectively collect and utilize the heat, thus greatly wasting thermal resources. [0004] The flushing s...

Problems solved by technology

The temperature of the freshly squeezed milk is generally about 37 degrees, and the milk is finally stored at about 4 degrees through the cooling system. The cooling system consumes a lot of energy and generates a lot of heat exchange. However, traditional milk storage facilities The cooling system does not effectively collect and utilize the heat, thus greatly wasting thermal resources

[0004] The flushing system is to flush the entire milking and milk storage facilities. The traditional way to dispose of the flushing water in the milking storage facilities is usually to discharge the environment directly without collecting, but after each round of milking, different temperatures are used. Clean water, acid / lye, clean water, and the necessary cleaning steps of rinsing with clean water before the next milking, resulting in a huge amount of rinsing water and complex components. In addition to the residual milk protein and milk fat in the milk, it also contains Acidic solution for removing residual protein and milk fat in milk

If reasonable and scientific collection and harmless treatment are not carried out, groundwater and soil will be polluted, and energy consumption (flush water temperature usually ≥ 45°C) will be wasted

[0005] In addition, the acid and lye after washing also have a certain pH value, which has a certain recycling value, and they are directly discharged as waste liquid, which will not only cause pollution but also cause waste
