What causes odor in screw chillers?

1. The so-called odor refers to the abnormal odor produced by the cooking ingredients and food in the screw chiller through physical and chemical changes under the influence of external factors. Over time, this odor adheres to the walls, ceilings, equipment and tools of the screw chiller. Generally speaking, there are several reasons for the odor in the screw chiller: There is an odor before the food enters the screw chiller. The food has been spoiled before entering the screw chiller, such as spoiled eggs, meat, fish, etc. The screw chiller that has stored fish, and the meat, eggs, or fruits and vegetables that have not been cleaned, cause the odor to infect and deteriorate. The screw chiller is poorly ventilated, and the temperature and humidity are too high, causing mold to multiply in large numbers and produce a musty odor. The leakage of the refrigeration pipe of the screw chiller and the erosion of the refrigerant (ammonia) into the food cause the odor to be generated. The temperature in the screw chiller does not drop, causing the meat to deteriorate and produce a corrupt smell. This situation often occurs when fresh meat is not frozen or frozen thoroughly before being transferred to the warehouse for storage. Foods with different smells are stored in a screw chiller warehouse, causing the food to odor each other.

2. Methods to prevent the generation of odor in the screw chiller Foods refrigerated in the screw chiller must be inspected and can only be stored in the warehouse if they are not deteriorated. There must be no odor in the screw chiller warehouse before receiving the goods. If there is any odor, it must be technically processed and can only be used after the odor is eliminated. Usually, the maintenance of refrigeration equipment should be strengthened, and it is strictly forbidden to unload goods by stacking to prevent the pipeline from being damaged and causing refrigerant leakage. During the cold processing of food, the screw chiller warehouse must maintain a certain temperature, and frozen food must not be transferred or stored. If the temperature in the screw chiller warehouse cannot be lowered, the cause should be found and the food can be processed after it is eliminated. Foods that may infect each other must not be mixed and stored in the screw chiller.
