Cleaning and disinfecting method for condensed milk glass bottle

Abstract

The invention discloses a cleaning and disinfecting method for a condensed milk glass bottle. The cleaning and disinfecting method comprises the following steps of 1) carrying out pre-cleaning, specifically, pouring clean water into the condensed milk glass bottle for soaking, and then pouring out the water so as to remove pollutants in the glass bottle; 2) draining off the glass bottle, specifically, placing the pre-cleaned glass bottle upside down, and draining off the glass bottle at normal temperature; 3) carrying out preheating, specifically, gradually heating the drained glass bottle to130 DEG C; 4) carrying out sterilizing, specifically, sterilizing the preheated glass bottle at the temperature of 130-150 DEG C; and 5) carrying out cooling, specifically, cooling the sterilized glass bottle at normal temperature. The cleaning and disinfecting method has the advantages of being green, safe, environmentally friendly, efficient and good in economic benefit, the cleaned and disinfected condensed milk glass bottle meets the standard requirements, the storage period is long, and the condensed milk glass bottle is suitable for production requirements.

Description

technical field [0001] The invention relates to a method for cleaning and disinfecting condensed milk glass bottles. Background technique [0002] Condensed milk is a milk product obtained by condensing raw milk after sterilizing and evaporating most of the water. Condensed milk is easy to store and has high nutritional value. Processing fresh milk into condensed milk can extend the storage period of the product on the one hand, and on the other hand, can also impart a unique flavor and become an auxiliary raw material for other foods, adding value and improving economic benefits. Refining in glass bottles is green, safe and healthy, and is very popular among consumers in Guangdong. Since the shelf life is stored at room temperature, and the shelf life is generally more than 3 months, the cleaning and disinfection process requirements for condensed milk glass bottles will be higher than those for refrigerated or post-sterilized products. [0003] At present, there is very...

AI Technical Summary

Problems solved by technology

At present, for the packaging materials of ready-to-eat glass bottles without post-sterilization, thermal cleaning, disinfection and drying are generally used. Due to the characteristics of glass bottles, glass bottles are prone to bursting when the temperature difference between hot water is large.

Existing industry technology generally uses 80-90°C hot water or hydrogen peroxide for a few seconds to sterilize. Due to the short sterilization time and low temperature, the disinfection of glass bottles is unqualified (there are microbial residues on the glass bottles), which affects the hygiene of the product shelf life. risk; at the same time, it causes waste of cleaning water, and the use of hydrogen peroxide is easy to cause residue

At present, there are few reports on this process at home and abroad, and it is urgent to develop a cleaning and disinfection technology solution suitable for this production process glass bottle
