Crisp & Low Breakage Rate｜TONLE Machinery Puffed Shrimp Sticks Frying Line

Puffed shrimp sticks have long been a hit in the snack industry. Boasting rich shrimp flavor and crispy texture, they enjoy steady bulk orders from supermarkets, snack chains and e-commerce platforms. As porous puffed blanks, shrimp stick preforms are thin and fragile. They expand rapidly once immersed in oil, making the frying process highly demanding. Minor errors easily lead to broken sticks, excessive oil absorption and uneven coloring, which are major headaches for scaled production in snack manufacturers.

Many snack factories adopt old frying machines and simple frying equipment to produce shrimp sticks, resulting in numerous production problems. Ordinary frying machines suffer from slow temperature response and large temperature differences inside the oil tank, so puffed shrimp sticks get heated unevenly. If the oil temperature is too high, the surface of shrimp sticks burns quickly with bitter taste, and broken fragments surge. If the temperature is insufficient, puffing becomes inadequate. The shrimp sticks turn hard instead of fluffy, absorbing excessive oil, leading to greasy finished goods and a greatly shortened shelf life. Slender shrimp stick blanks tend to float and tangle after entering the frying machine, producing lots of broken strips after discharge and dragging down the yield rate. Fine residues generated during frying sink continuously to the bottom of the oil tank, carbonizing and darkening rapidly, accelerating oil oxidation. Factories have to replace cooking oil frequently. Burnt residues also bring bitter odor to shrimp sticks and raise costs of raw materials and oil.

Tonle Machinery puffed shrimp stick frying line is custom-developed for puffed snacks. The complete frying unit is equipped with an intelligent temperature control system. The frying machine monitors oil temperature in real time and compensates automatically to maintain stable and uniform temperature across the whole oil tank. The adjustable-speed conveyor mesh belt with limiting baffles transports shrimp stick blanks steadily. It effectively prevents floating accumulation and collision between materials, greatly reducing broken strips and scraps. Finished shrimp sticks feature uniform shape, consistent puffing degree and stable golden color.

This frying line is fitted with a continuous residue filtering device. Tiny frying scraps are separated and discharged timely to avoid carbonization inside oil, slowing oil aging and cutting oil consumption. The whole machine is built with food-grade stainless steel. Modules including the frying machine, conveying section and oil draining machine can be disassembled for dead-angle-free cleaning, complying with food safety standards. The full production line runs automatically and continuously. Feeding, frying and oil draining are completed in one go, cutting manual intervention and labor costs. Production capacity can be adjusted flexibly to fit small, medium and large puffed food factories.
