Problems solved by technology

[0007] The temperature of CIP cleaning is mostly around 85°C, or even higher. Therefore, after using the existing artificial dirt to verify the laboratory effect of CIP cleaners, there will be decontamination effects of detergents suitable for artificial dirt in actual CIP operations. Poor, cannot achieve good cleaning results, it is difficult to obtain a cleaning agent suitable for CIP cleaning

preparation example Construction

[0026] The present invention also provides a preparation method for artificially simulating UHT dirt, comprising the following steps:

[0027] Mix 60-80ml of pure milk, 2-3g of tea polyphenols, 0.1-1.5g of carbon black, 0.1-0.5g of sodium percarbonate, 0.1-1.5g of sugar and add water to 100g to form a dirt solution, and mix 0.2-0.5ml of the dirt solution Applied on the stainless steel hanging piece; placed in an environment with a temperature of 20-40°C and a humidity of 75-80% for aging for 36-48 hours, then placed in an autoclave with a temperature of 120-140°C for 30-60 minutes, and finally put Aging for at least 24 hours in an environment with a temperature of 20-40°C and a humidity of 75-80%.

[0028] Wherein, the aging time and specific temperature and humidity can be adjusted according to actual needs. In this embodiment, the temperature for the first aging is 35°C, the humidity is 75%, and the aging time is 40h; the pressure in the autoclave is greater than 0.2MPa , t...

Embodiment 1

[0032] Mix 60ml of pure milk, 2g of tea polyphenols, 0.1g of carbon black, 0.1g of sodium percarbonate, 0.1g of sugar, and add water to 100g to form a dirt solution. Apply 0.2ml of the dirt solution to the stainless steel hanging piece; place it at a temperature of 40°C After aging for 48 hours in an environment with a humidity of 75%, put it into an autoclave at a temperature of 140°C and heat it for 30 minutes, and finally put it into an environment with a temperature of 20°C and a humidity of 75% for 30 hours.

Embodiment 2

[0034] Mix 80ml of pure milk, 3g of tea polyphenols, 1.5g of carbon black, 0.5g of sodium percarbonate, 1.5g of sugar and water to 100g to form a dirt solution, and apply 0.5ml of the dirt solution on the stainless steel hanging piece; place it at a temperature of 40°C After aging for 48 hours in an environment with a humidity of 80%, put it into an autoclave at a temperature of 120°C and heat it for 30 minutes, and finally put it into an environment with a temperature of 40°C and a humidity of 80% for 35 hours.

Abstract

The invention discloses a UHT dirt in artificially simulating the production of dairy products and milk tea beverages and a preparation method thereof, and relates to the field of dirt cleaning. Every 100g of dirt includes: 60-80ml of pure milk, 2-3g of tea polyphenols, 0.1- 1.5g carbon black, 0.1-0.5g sodium percarbonate, 0.1-1.5g sugar, the balance is water; the preparation method is: 60-80ml pure milk, 2-3g tea polyphenols, 0.1-1.5g carbon black, 0.1 ~0.5g of sodium percarbonate, 0.1~1.5g of sugar, add water to 100g and mix evenly to form a dirt solution, apply 0.2~0.5ml of the dirt solution on the stainless steel coupon; place it in a room with a temperature of 20~40°C and a humidity of 75~80%. After aging in the environment for 36-48 hours, put it into an autoclave at a temperature of 120-140°C and heat it for 30-60 minutes, and finally put it into an environment with a temperature of 20-40°C and a humidity of 75-80% for at least 24 hours. The invention can obtain the dirt with high similarity to the actual dirt, and is convenient for verifying the effect of the cleaning agent formula.

Description

technical field [0001] The invention relates to the field of dirt cleaning, in particular to an artificially simulated UHT dirt in the production of dairy products and milk tea drinks and a preparation method thereof. Background technique [0002] UHT (English full name: Ultra High Temperature Treated, ultra-high temperature disinfection method) is a method of sterilizing food by heating (130-150°C) in a very short time (2-3 seconds), which can quickly kill The spores left in milk and beverages are widely used in the production of milk, fruit juice, cream, soy milk, yogurt, wine, soup, honey and thick soup. [0003] In the production of food and beverage, after a certain period of production, the production equipment needs to be cleaned in place. The industry is called CIP. The residue left on the surface of the equipment can promote the growth of microorganisms. In order to protect consumers from pathogens or poisons Associated potential health hazard effects, maintaining ...
