Food Residue Cleaning from Packages

Cleaning compositions for removing chewing gum and other sticky substances from surfaces. The compositions contain a diluent like water, a polyol like propylene glycol, an alkyl ester like polysorbate 80, and optionally other ingredients like surfactants, fragrances, and pH adjusters. The compositions can be sprayed onto surfaces to easily clean and rinse off the sticky residue without leaving a residue themselves. The polyol and alkyl ester help disperse the sticky substance in the cleaning solution. The compositions can have a wide range of diluent content from 1% to 50%.

Cleaning device for removing oil stains from packaged food using a rotating drum with water spray and scraping blades. The device has a cleaning tank with a conveyor belt to feed packaged food in. Inside the tank is a horizontally mounted drum with a roller that can rotate. The drum has water spray holes, leakage holes, and a spiral blade on the inside wall. Water sprays onto the food as it rotates in the drum. The spiral blade scrapes the food. This combined cleaning action removes oil better than just vibration. The drum rotates using a gear system.

Cleaning compositions for removing chewing gum and sticky substances from surfaces using environmentally desirable solvents like polyols, alkyl esters, and diluents. The compositions provide superior cleaning compared to d-limonene and other solvents. They contain diluents like propylene glycol, polyols like glycerin, and alkyl esters like ethyl lactate. These solvents are mixed in specific ranges to create compositions that can clean sticky residues without rinsing. The compositions can be applied via spraying or scraping and can remove chewing gum without rinsing.

A bagged food cleaning device that effectively cleans packaged foods like instant meals. The device has a tank with a brush roller inside the funnel-shaped inlet. The tank also has a stirring rod and a door to discharge the cleaned food. The brush rollers rotate to agitate the food as it enters the tank. A lever stirs the contents. This ensures thorough cleaning of the bags as they are submerged and agitated in the tank.

Cleaning method for food processing equipment that reduces water usage and eliminates the need for a pre-rinse step in clean-in-place (CIP) systems. The method involves circulating a single cleaning solution containing an acidic detergent through the equipment without prior rinsing. The cleaning solution contacts the soiled surfaces and removes the contaminants. This is followed by post-rinsing to remove residual detergent. The reduced water usage comes from eliminating the pre-rinse step and using less water for the cleaning solution compared to traditional CIP cycles. The acidic detergent allows effective cleaning without chlorine or chlorinated alkaline detergents.

Packaging material cleaning machine that can effectively clean and wash bag-shaped packaging made of materials like vinyl, paper, aluminum, or composite laminates. The machine uses rotating blades and a processing tank with recesses to cut and wash the inside of the bags. The blades and recesses allow the bags to be forcibly cut into pieces as they rotate. Washing water injected into the tank cleans the bag pieces. This allows thorough cleaning of food residue inside bagged products made of materials that can't be crushed like soft vinyl or composite materials. The machine design with detachable skewers, upright cutting blades, and multiple blades prevents cutting hazards and allows easy maintenance.

Cleaning method for dishwashers that improves cleaning performance by using a pre-washing step with a concentrated detergent mist. In the pre-washing step, a mist of highly concentrated cleaning fluid is sprayed onto the items to be washed. This allows the detergent to coat and penetrate the stuck-on food debris. After a short time, the main washing step removes the loosened debris using the regular cleaning fluid. This two-step process provides significantly better cleaning compared to just using tap water for pre-washing.

Efficiently removing foreign substances like lubricants and chips adhering to food packaging containers made from aluminum foil. The method involves heating the containers and blowing hot air on them to remove the adhered foreign matter. This reduces the amount of lubricant needed for cold press molding and allows efficient removal without using cleaning liquids or drying steps. It simplifies the cleaning process and enables sterilization in one step.
