Problems solved by technology

Product fouling leads to carbonization of substances in the tube, which affects the flavor of the product; leads to poor heat transfer, and the central temperature cannot meet the sterilization requirements, resulting in secondary sterilization, resulting in increased energy consumption, increased product loss, increased maintenance costs, and ultimately resulting in high production costs. , affecting the economic benefits of the product

Embodiment 1

[0025] Example 1: Enter the prepared corn compound nutrient thick slurry from the material inlet, enter the preheating cooler through the pump, preheat to 70°C, put it into the degassing equipment for degassing, the degassing pressure is -30kPa, and then enter the homogenization The homogenizer is used for homogenization, and the homogeneous pressure is 20MPa. Then enter the ultra-high temperature sterilizer, the heater is heated to 95°C for the first time, then heated to 120°C for the second time, and heated to 140°C for the third time, enters the heat preservation tube for 20 seconds, and enters the pre-heating stage of the sterilizer after being cooled by the cooler. Cool in a thermal cooler, then cool with ice water. Cool to a temperature of 20°C, transfer to aseptic tanks, and then fill. After 44 hours, the sterilizer is cleaned in place, and the sterilized thick slurry temporarily stored in the aseptic tank can be continuously transported to the filling section for fill...

Embodiment 2

[0026] Embodiment 2: Enter the red bean compound nutrient thick slurry prepared from the material inlet, enter the preheating cooler through the pump, preheat to 70°C, put it into the degassing equipment for degassing, the degassing pressure is -50kPa, and then enter the homogenization The homogenizer is homogeneous, and the homogeneous pressure is 25MPa. Then enter the ultra-high temperature sterilizer and heat the heater to 90°C for the first time, then heat it to 115°C for the second time, and heat it to 138°C for the third time. Preheat cooler to cool, then cool with ice water. Cool to a temperature of 20°C, transfer to aseptic tanks, and then fill. After 44 hours, the sterilizer is cleaned in place, and the sterilized thick slurry temporarily stored in the aseptic tank can continue to be transported to the filling section for filling, and the filling cycle is extended to 72 hours.

Embodiment 3

[0027] Example 3: Enter the oat compound nutrient thick slurry prepared from the material inlet, enter the preheating cooling section through the pump, preheat to 70°C, put it into the degassing equipment for degassing, the degassing pressure is -60kPa, and then enter the homogenization The homogenizer is homogeneous, and the homogeneous pressure is 25MPa. Then enter the ultra-high temperature sterilizer and heat the heater to 90°C for the first time, then heat it to 115°C for the second time, and heat it to 138°C for the third time, enter the heat preservation tube for 30 seconds, and enter the sterilizer after being cooled by the cooler. Preheat cooler to cool, then cool with ice water. Cool to a temperature of 25°C, transfer to aseptic tanks, and then fill. After 46 hours, the sterilizer is cleaned in place, and the sterilized thick slurry temporarily stored in the aseptic tank can continue to be transported to the filling section for filling, and the filling cycle is exte...

Abstract

A method for sterilizing and filling a liquid cereal product relates to a liquid cereal product. The invention provides the method for sterilizing and filling the liquid cereal product, which comprises the following steps: feeding liquid cereals from a material inlet, pumping the liquid cereals with a product pump into a preheating cooler for preheating; degassing the preheated liquid cereals, homogenizing the liquid cereals, and feeding the liquid cereals into a heater of an ultra-high-temperature sterilizer for primary heating; heating the homogenized and heated liquid cereals for the second time; heating the liquid cereals which is heated for the second time for the third time and keeping temperature; and after cooling the liquid cereals of which the temperature is kept with the cooler, cooling the liquid cereals in a preheating cooler of a sterilizer, reducing temperature with ice water, conveying the liquid cereals to an aseptic can, connecting the aseptic can to a filling machine, and performing aseptic filling on the liquid cereals. Because a sterilization temperature rise mode is changed to a four-section mode, namely preheating, primary heating, secondary heating and tertiary heating, the temperature difference between a medium and the material is kept constant and a scaling time can be effectively delayed to 4.6h.

Description

technical field [0001] The invention relates to a liquid cereal product, in particular to a method for sterilizing and filling the liquid cereal product. Background technique [0002] With the improvement of people's living standards, people have a new understanding of dietary structure. It is no longer the more nutritious the better, but the emphasis on balance, variety and appropriate amount. Cereals, as the main body of traditional Chinese diet, are not only rich in complex carbohydrates, which can provide "vegetable energy", which is conducive to nutritional balance; but also rich in cellulose, which is beneficial to improve intestinal function and reduce blood cholesterol levels. It has a preventive effect on cardiovascular disease and diabetes. In addition, grains also provide plant protein, magnesium, potassium, phosphorus, iron and other elements and vitamin B group. Now more and more people are beginning to realize the benefits of cereals, and cereals are also eme...
