example 1

[0067] Example 1 : Conduct laboratory studies to generate cleaning efficiency data for different CIP compositions and protocol phases. A basic CIP protocol has five stages: a) rinse with water, b) first chemical effect, c) rinse with water, d) second chemical effect and e) rinse with water; in addition there is a final disinfection step.

[0068] Preparation of test models: Soiled food panels were obtained by the following method.

[0069] A. Clean the stainless steel panels with ethanol and dry in a hot air oven at 105°C for 1 hour. Weigh it to 4 digits. It was then placed in an oven preheated to 220°C. A 2 ml liquid food sample (eg Lipton iced tea / tomato soup) is applied to an area of ​​approximately 20 cm2. It was baked at 220°C for 1 hour. The panels were then cooled and weighed again to 4 digits.

[0070] B. Piping pieces containing tea soil and milk tea soil were collected from the actual tea and coffee beverage manufacturing site and cut into small boards / panels....

example 2

[0071] Example 2 : demonstrates the in-situ cleaning of panels with black and milk tea soils obtained according to the method described in Example 1B). After the pre-rinse step, the test panel is placed in the beaker containing the first chemical solution at the desired temperature. It should be noted that the temperatures described herein are the temperatures of the reagents for a given time by CIP. It was further rinsed with water and placed in a second chemical solution. Finally, rinse again with water and dry in an oven at 100° C. for 1 hour. Record the weight of each cleaned panel to calculate weight loss. Details of the cleaning compositions are reported in Table 1 below.

[0072] In this cleaning evaluation, each test panel was evaluated for visual observation and weight loss after cleaning.

[0073] It can be seen from Tables 2 and 3 that the combination of oxidizing agent and acid has a significant cleaning synergistic effect, while caustic is completely incapab...

example 3

[0083] Example 3: Additionally, two specific protocols were performed to examine the cleaning efficiency of potassium permanganate as given below.

[0084] Scheme 1: Place the dirt panel in a solution containing 5% sodium hydroxide and 0.5% potassium permanganate at a solution temperature of 80° C. for 30 minutes. Rinse with water at room temperature. The panels were then removed and placed in a solution comprising 0.77% nitric acid, 0.14% phosphoric acid and 1% ferrous sulfate at a temperature of 80° C. for 10 minutes. The panels were dried in an oven at 100°C for 1 hour.

[0085] Protocol 2: The soiled panel was placed in a solution containing 1.9% nitric acid and 0.35% phosphoric acid and 0.5% potassium permanganate at a temperature of 50 to 80° C. for 30 minutes. Rinse with water with 0.005% w / w peracetic acid and 0.02% w / w hydrogen peroxide at room temperature. The panels were dried in an oven at 100°C for 1 hour.

Abstract

The invention relates to a cleaning-in-place process and a cleaning composition thereof. More specifically, the invention relates to a cleaning process for removing burning food dirts attached to internal metal surfaces or connections of a food processing device and a prepared production line. The CIP method includes: enabing the dirts to make contact with an oxidation composition to oxidize the dirts and make the dirts be dissolved at a high temperature so that the removal of the dirts from the metal surfaces can be facilitated. Besides, the method comprises making decontaminating and disinfecting solutions to pass.

Description

technical field [0001] The present invention relates to cleaning-in-place processes and cleaning compositions thereof. More particularly, the present invention relates to a cleaning process for removing food-based soils adhering to internal metal surfaces or joints of food processing equipment and post-preparation production lines. Background technique [0002] In recent years, types of ready-to-drink / ready-to-eat beverages such as tea or coffee have experienced rapid growth due to the combination of the advantages of tea as a healthy beverage and the portability of ready-to-use prepared beverages. In making this type of drink, the leaves or beans are heated, causing them to release volatile compounds. Additionally, many food and beverage products are concentrated or formed by evaporation. Industrially processed ready-to-drink beverages may contain a variety of additives including flavors, sweeteners, carbohydrates, vegetable oils, mineral salts, food additives, proteins o...
