Ultrasonic duel sleeve coil pipe type milk liquid sterilizing system

Abstract

The invention relates to an ultrasonic duel sleeve coil pipe type milk liquid sterilizing system. The system is characterized in that a feeding tank is connected to a balancing groove through a feeding pump, and the balancing groove is connected to a duel sleeve coil pipe through a sterile pump; a coil pipe is annularly arranged in a heating chamber, and two ends of the coil pipe stretch out of the heating chamber; the duel sleeve coil pipe is connected with one end of the coil pipe, the other end of the coil pipe is connected to a maintaining pipe, a reversing valve is arranged at the top endof the maintaining pipe, a separation cooler is connected to one end of the reversing valve through a pipeline and is connected to the balancing groove, and the other end of the reversing valve is connected with a feeding hole of the duel sleeve coil pipe; a heat exchanger is connected to a discharging hole of the duel sleeve coil pipe; and a water inlet, a water outlet and a draining hole are formed in the heating chamber, and the water inlet and the water outlet are connected to a heat source unit. The ultrasonic duel sleeve coil pipe type milk liquid sterilizing system is scientific and reasonable in structural design and convenient to operate, the energy is saved, constant-temperature effective sterilization of milk liquid can be guaranteed, nutrients and taste of the milk liquid arenot damaged, and meanwhile, phenomena including scaling and coking can be eliminated, so that cleaning of equipment is reduced.

Description

technical field [0001] The invention belongs to the field of milk sterilization processing, and relates to milk sterilization equipment, in particular to an ultrasonic double-coil milk sterilization system. Background technique [0002] Dairy products are essential nutrients in our daily life, but they have a short shelf life and are easy to deteriorate. Therefore, proper sterilization must be done to improve the quality of milk and ensure the nutritional needs of life. [0003] At present, the sterilization methods used in my country are mainly pasteurization and ultra-high temperature instantaneous sterilization. The long-term and slow heat treatment of pasteurization leads to serious damage to nutrients and flavors; The consumption is large, and the cooling capacity consumption is also large. Moreover, this type of indirect sterilization is prone to fouling and coking, which affects the sterilization temperature, and the cleaning interval is short. [0004] Based on this...

Problems solved by technology

[0002] Milk products are essential nutrients in our daily life, but the shelf life of milk products is short and they are easy to deteriorate. Therefore, proper sterilization must be done to improve the quality of milk and ensure the nutritional needs of life

[0003] At present, the sterilization methods used in my country are mainly pasteurization and ultra-high temperature instantaneous sterilization. The long-term and slow heat treatment of pasteurization leads to serious damage to nutrients and flavors; ultra-high temperature instantaneous sterilization operation is more troublesome, steam High energy consumption and high cooling capacity

Moreover, this type of indirect sterilization is prone to fouling and coking, which affects the sterilization temperature and the cleaning interval is short
