Processing Line & Brief Description

The pre-processing equipment for aquatic products freezing includes: shrimp grading machine, shrimp boiling machine, shelling machine, shrimp back-opening machine, fish granding machine, fish-opening machine, peeling machine, etc. The quick-freezing equipment cools and freezes the products through the conveyor line.
According to different pretreatment methods, the temperature at which aquatic products enter the quick-freezing equipment will be different. The cooked shrimp is cooled with ice water before freezing, and then enters the quick-freezing equipment after cooling, which can save costs.
According to the different freezing capacity, IQF spiral freezer is recommended for 500kg/h-4000kg/h, and IQF tunnel freezers can be used for 2000kg/h and below, impingement tunnel freezer is more efficient. If product is shrimp meat, use a stainless steel belt tunnel freezer. The frozen shrimp meat are very beautiful and there is no trace of the mesh belt. The current advanced technology can complete the freezing within 3 minutes. 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 the spiral freezer is relatively high. If it is a new factory, you can contact us before construction. We have rich practical experience in food factories and can provide free technical support, so that you can avoid wasting energy due to ignorance of the processing process.
If the finished aquatic product needs to be frozen in block, for example, the finished product can be made into rectangular fish bricks, surimi, etc., the plate freezer can be used. 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.
