The pre-treatment of prepared food for freezing requires steaming, frying, etc. The food processed by the pre-processing equipment passes through the conveying line to the quick-freezing equipment for cooling and freezing.
According to different pretreatment methods, the temperature of processed food entering the quick-freezing equipment will be different. High-temperature products are cooled first, and then enter the quick-freezing equipment, saving costs.
According to the different freezing capacity, the IQF spiral freezer is recommended for 200kg/h-4000kg/h, and the IQF tunnel freezer for 2000kg/h and below, impingement tunnel freezer can be selected for higher efficiency. According to the actual area of ​​the plant, combined with the characteristics of the tunnel freezer and the spiral freezer, select the appropriate iqf freezer. The tunnel freezer is relatively long and spiral freezer is relatively high. If it is a new factory, you can contact us before construction. We have a wealth of practical experience in food factories and can provide free technical support to prevent you from ignoring the processing process and wasting energy.
The prepared food can also be packaged in trays or other packaging methods, placed in a plate freezer, and frozen by the plate freezer. It is suitable for customers with small output and small budget. According to the size and water content of the product, the general freezing capacity is 300kg/batch-1500kg/batch, about 3 hours each batch. The plate freezer can also be made into multiple production lines to freeze at the same time, and is widely used in some European countries.
After the freezing is completed, the packaging is completed through the automatic packaging production line, and finally sent to the cold storage.
