Problems solved by technology

The existing ultra-high temperature sterilization device adopts the electric direct drive method. The problem of this kind of product is that it does not save energy, which is contrary to the idea of ​​energy saving and emission reduction in my country.
However, the existing room temperature milk sterilization equipment uses electric direct drive heating, which consumes a lot of energy. If the air source heat pump is applied to room temperature milk sterilization equipment, energy consumption can be greatly reduced

Abstract

The invention discloses a cascade air source ultrahigh-temperature instantaneous sterilization device and method, and belongs to the technical field of electric appliances. A feeding butterfly valve is connected with a material pump, the material pump is connected with a double-sleeve coil through a pipeline, a high-temperature coil in the tank is located on the side face of the double-sleeve coil, the other end of the double-sleeve coil is connected with a high-pressure barrel, a throttling valve is connected with the high-pressure barrel and the discharging butterfly valve respectively, andthe throttling valve is connected with the high-pressure barrel and the discharging butterfly valve respectively and a circulating storage tank is connected with the discharging butterfly valve. The tank body is connected with the liquid outlet, the evaporator is connected with the refrigerant steam inlet end of the low-temperature compressor, the refrigerant steam outlet end of the low-temperature compressor is connected with the condenser, the outlet end of the condenser is connected with a first throttling valve, and the other end of the first throttling valve is connected with a refrigerant steam inlet side of the evaporator. Carbon dioxide is used as a refrigerant, heat in air is extracted by utilizing an electric heat pump in the sterilization process of the sterilization device andthe acid washing and alkali washing processes to heat water vapor in the sterilization device, so that the water vapor reaches the temperature in the sterilization and cleaning processes, and the milkis sterilized.

Description

technical field [0001] The invention relates to a cascading air source ultra-high temperature instantaneous sterilization device and method, and belongs to the technical field of electric appliances. Background technique [0002] According to statistics, about 300 million people insist on drinking milk every day. Agricultural milk is a popular daily product. In order to ensure its safety, sterilization equipment is essential. Among them, ultra-high temperature instantaneous sterilization (UHT) is commonly used to sterilize room temperature milk. The existing ultra-high temperature sterilization device adopts the method of electric direct drive. The problem of this kind of product is that it does not save energy, which deviates from the idea of ​​energy saving and emission reduction in my country. At present, most of the refrigerants used in heat pumps are freon, and the chemically synthesized freon has a high ODP value and a high GWP value, which is not environmentally frie...
