Coating Locked & Anti-shrinking, Crisp & Tender Texture｜TONLE Machinery Automatic Squid Rings Frying Line

Fried squid rings are widely popular seafood snacks, western side dishes, hot pot ingredients and prefabricated delicacies. Thanks to their crispy crust, tender chewy meat and fresh delicious taste, they enjoy high repurchase rates and become major profitable products for seafood deep processing factories. Squid rings feature high water content and delicate texture, which makes frying processing extremely difficult. Traditional frying equipment adopts rough processing modes with inaccurate temperature control. Large-scale feeding easily brings various quality defects. Low oil temperature leads to excessive oil absorption, limp crust and greasy taste. Excessively high temperature will scorch the surface while the inside remains undercooked. Moreover, squid tends to shrink and shed batter or bread crumbs when heated, resulting in irregular shapes and poor appearance of finished products. Residues of batter and seafood scraps will carbonize after repeated heating, accelerating oil deterioration and increasing oil replacement costs. Residual fishy odor also causes unstable taste among batches, failing to meet unified supply standards for chain brands and supermarkets.

In view of squid rings’ characteristics such as high moisture, easy shrinkage, coating shedding and stiff texture after prolonged frying, Tonle Machinery independently develops the automatic squid ring frying line, which is applicable for mass production of plain, batter-coated and breaded squid rings, solving many drawbacks of traditional equipment. The integrated production line includes automatic feeding, zoned constant-temperature shaping, anti-shrinking frying, negative-pressure deoiling, closed-loop oil filtration, air cooling crisp retention and automatic discharging. Manual stirring, sorting and temperature adjustment are no longer needed. Reliance on empirical manual operation is eliminated, so appearance, crispness and tenderness of finished products stay consistent in each batch, greatly raising yield and productivity.

Equipped with exclusive intelligent zoned temperature control system for seafood, the equipment locks the optimal frying temperature range for squid rings and provides real-time dynamic heat compensation to eliminate temperature drops caused by concentrated feeding and maintain balanced heating. Segmented heating technology is applied: the early constant-temperature stage quickly shapes products, solidifies outer coating to prevent shedding and restrain thermal shrinkage to regularize shapes; the later uniform heating stage delivers mild heat penetration to remove excess moisture and fishy odor, avoiding stiff and dry meat after long frying. Finished squid rings own thin crispy crust without scorched spots, juicy tender squid meat and pure fresh flavor with low oil content, guaranteeing stable batch quality.

Considering the ring-shaped structure which is easy to pile up and rub off coatings, customized low-vibration smooth conveyor belts are equipped to separate materials orderly, preventing extrusion, friction and damage, thus reducing coating loss and breakage rate effectively. Variable frequency stepless speed regulation allows flexible adjustment of frying time and conveying speed according to ring size, coating thickness and taste requirements, supporting rapid process switching and diversified customized production. The circulating filtration system continuously cleans crumbs, seafood residues and carbonized impurities, purifies frying oil, slows oil oxidation and extends oil service life, cutting long-term production costs and material loss greatly.

The whole machine is made of 304 food-grade stainless steel. Seamless structure eliminates sanitary dead corners, with outstanding high-temperature resistance, oil resistance and corrosion resistance. Detachable components support comprehensive cleaning and disinfection without residual scraps and odors, fully complying with food safety standards and all health inspections. Featuring stable operation, low failure rate and simple maintenance, the equipment supports 24-hour non-stop production to match high-intensity standardized production demands of seafood manufacturers.

The prefabricated seafood snack market is increasingly refined. Neat appearance, stable crisp tender taste and low greasiness become core competitive strengths. With mature seafood frying technology, reliable equipment quality and full-cycle after-sales service, Tonle Machinery helps manufacturers solve common problems of squid ring production including shrinkage deformation, coating falling off, color difference, stiff texture and high oil consumption, realizing quality improvement, cost reduction and efficient stable production to strengthen market competitiveness continuously.
