The so-called peculiar smell, that is, under the influence of external factors, the cooking materials and food of the water-cooled chiller will produce an abnormal smell through physical and chemical changes. Over time, this smell will adhere to the wall and ceiling of the screw chiller. and on equipment and tools. The peculiar smell in the screw chiller is generally caused by the following factors: The screw chiller has a peculiar smell before food is fed. Before entering the screw chiller, the food will be eroded and transformed, such as transformed eggs and fish. The screw chiller that has stored fish has stored meat, eggs, fruits and vegetables and other foods without cleaning, resulting in odor infection and deterioration. The screw chiller is poorly ventilated and the temperature and humidity are too high, which causes a large number of molds to multiply and a moldy smell occurs. The leakage of the refrigeration pipeline of the screw chiller, the refrigerant (ammonia) is eroded into the food, and the odor occurs. The temperature in the screw chiller does not decrease, resulting in the deterioration of the meat and the rotten taste. This situation mostly occurs when the fresh meat is transferred to the warehouse before it is completely frozen. Foods with different smells are stored in a screw chiller warehouse, causing the food to be infected with each other.
The way to avoid the odor of the water-cooled chiller The food that is refrigerated by the water-cooled chiller must pass the inspection, and the food that has not changed can be stored in the warehouse. The screw chiller warehouse must not have peculiar smell before purchasing. If there is peculiar smell, it must be dealt with technically and can be used after removing the peculiar smell. Usually, it is necessary to strengthen the protection of refrigeration equipment, and prohibit dumping and unloading, so as to avoid smashing the pipeline and causing refrigerant leakage. During the cold processing of food, it is necessary to keep the screw chiller warehouse at a certain temperature, and it is not allowed to transfer or store frozen food. If the temperature of the screw chiller warehouse cannot be lowered, the factors should be found, and food processing should be carried out after cleaning. Mutual infected food shall not be mixed and stored in the screw chiller.
