Donut Frying Line, Solve Baking Frying Production Challenges

When bakeries mass-produce donuts, they often encounter various troubles in the frying process. Traditional batch fryers require high labor costs for manual monitoring. Once dough enters the oil tank, the oil temperature drops sharply, resulting in uneven coloring of donuts, with some burnt and some undercooked. Dough crumbs generated during frying keep carbonizing, contaminating cooking oil, causing heavy oil loss and unstable oil absorption rate of finished products, leading to inconsistent texture. Meanwhile, old fryers struggle to unify frying duration. Manual flipping easily deforms donuts and causes big quality differences between batches, restricting large-scale brand development. TONLE Machinery devotes itself to R&D of frying equipment and launches the automatic donut frying line. Our professional fryers solve pain points in continuous donut production and help food factories achieve stable mass production.

This donut frying line is specially designed for floating flour products. The core fryer adopts a double-layer pressing mesh belt structure. After donuts go into oil, they are restrained by the mesh belt and automatically fried on both sides, avoiding uneven flipping, product deviation and deformation. The whole frying line is equipped with an intelligent temperature control system to compensate heat in real time with slight oil temperature fluctuation. It precisely matches the frying temperature required for donuts and ensures uniform golden and fluffy crust for every batch of donuts. The fryer is equipped with an on-line filtering and slag removal device to continuously filter dough scraps during production, reduce oil carbonization, extend oil service life and cut raw material operating costs.

TONLE frying line is entirely made of 304 stainless steel. The food-grade material meets food safety production standards. The frying line is fitted with variable frequency speed regulation device. Conveyor speed can be flexibly adjusted to freely control the residence time of donuts inside the fryer, adapting to various product processes including original donuts, filled donuts and mini donuts. The complete frying line realizes continuous feeding, continuous frying and automatic discharging. A large number of workers for flipping and fishing materials are no longer needed, greatly cutting labor costs. The modular design of the fryer enables easy disassembly, assembly and cleaning, saving cleaning time and meeting multi-shift continuous production requirements of food factories.

Different from ordinary simple fryers, TONLE donut frying line can connect with front forming equipment and rear cooling, sugar coating and packaging processes to build an integrated production line. With nearly 20 years of equipment manufacturing experience, our equipment is certified by ISO9001 and CE. Customized size and supporting solutions of frying lines are available according to workshop space and capacity demands. We provide one-stop service covering equipment design, manufacturing, on-site installation & commissioning and after-sales maintenance.

Choose professional fryers to stabilize finished donut quality and boost workshop output. TONLE frying line is the preferred equipment for baking enterprises to expand donut production and control production costs. It helps factories get rid of unstable frying quality and realize standardized, automatic continuous production.
