TONLE Machinery Automatic Fish Tofu Frying Production Line

2026-07-30 13:43

Frozen fish tofu, fresh-style fish tofu and various surimi products are core circulating products in the supply chains of hot pot ingredients, oden, mala tang and prepared dishes. They boast a huge market volume, stable annual demand and strong repeat purchase rates. Made from surimi, starch and food auxiliary materials through molding and steaming, high-quality fish tofu features uniform golden color, smooth and dry surface, evenly distributed internal pores, tender and firm texture, regular shape and non-loose cuts. The traditional intermittent manual frying mode has many drawbacks in mass production. Disordered manual stacking leads to uneven heating and obvious color difference. Manual temperature control has large errors and frequent fluctuations, causing excessive oil absorption and greasy taste at low temperatures, and burnt surface with undercooked interior at high temperatures, making quality control difficult. Surimi and starch residues fall into the oil continuously and carbonize at high temperature, resulting in turbid and odorous oil that requires frequent replacement and increases production costs. Without unified manual operation standards, batches differ greatly in color, tenderness and moisture content, failing to meet the standardized continuous mass production and stable supply needs of large food enterprises.

As a professional frying equipment manufacturer, Taile Machinery specializes in the R&D and production of surimi processing equipment. Targeting the production characteristics of fish tofu such as high tenderness requirements, easy coloring, large residue output and difficult batch quality control, we have developed a dedicated automatic continuous frying line. It is suitable for mass continuous processing of frozen, fresh and hot-pot-specific fish tofu and other surimi products. The integrated production process includes automatic regular feeding, segmented constant-temperature frying, online residue scraping and oil filtering, continuous oil draining and cooling, and automatic discharging. It solves common industry problems including uneven coloring, local scorching, insufficient elasticity, high oil absorption, rapid oil aging and unstable batch quality, serving as core equipment for standardized, energy-saving and large-scale production of frozen fish tofu.

1. Widened Low-disturbance Conveyor Belt, Ensuring Complete Product Shape

Fish tofu is tender and soft, prone to softening and adhesion after heating. Ordinary conveyor belts with severe vibration and friction easily cause product displacement, stacking and deformation. Taile Machinery’s dedicated fish tofu frying line is equipped with a widened, encrypted and low-disturbance flexible conveyor belt with mesh sizes adapted to block-shaped fish tofu, effectively reducing jamming, leakage and friction damage. Optional flexible limit baffles enable uniform material arrangement and avoid extrusion and adhesion. Equipped with a variable-frequency stepless speed regulation system, the equipment can adjust frying duration flexibly according to product thickness, cooking state and processing technology, ensuring regular shape, uniform color and tender texture of each fish tofu and greatly improving the qualified rate and commodity value of finished products.

2. PLC Segmented Constant Temperature Control, Unified Batch Color and Tenderness

Fish tofu has a fine internal structure with different heating rhythms for the surface and interior. A single oil temperature cannot balance surface coloring and internal cooking quality. Low temperature leads to excessive oil absorption and greasy taste, while high temperature causes hard surface, disordered internal pores and reduced elasticity. The equipment adopts a high-precision PLC intelligent zoned temperature control system with stable accuracy and exclusive two-stage frying technology. The high-temperature shaping zone quickly tightens the surface for uniform golden coloring and reduces oil adsorption. The constant-temperature curing zone enables even heat penetration to ensure fully cooked products with uniform internal pores and consistent tenderness. The system supports real-time oil temperature monitoring, automatic heat compensation and over-temperature acousto-optic alarm, enabling 24-hour non-stop continuous production. All batches maintain consistent color, taste, moisture content and elasticity, seamlessly connecting with subsequent air cooling, quick freezing and packaging processes.

3. Online Continuous Residue Scraping & Multi-stage Oil Filtration, Reducing Oil Consumption

Surimi debris, starch particles and auxiliary residues continuously fall off during frying. Long-term high-temperature carbonization of fine impurities causes oil darkening and peculiar smells, and residual impurities affect product appearance and flavor. The equipment is equipped with a bottom longitudinal automatic continuous residue scraping mechanism to clean settled residues uninterruptedly and avoid persistent oil pollution. The external multi-stage hot oil circulating filtration system intercepts suspended fine particles precisely to keep the frying oil clean and transparent. It effectively delays oil acidification and deterioration, extends oil service life, reduces replacement frequency and cuts long-term production consumable costs, stably producing high-quality fish tofu with consistent appearance and flavor.

4. Thickened 304 Food-grade Stainless Steel Body, Sanitary and Dead-corner-free Cleaning

Surimi processing workshops feature high humidity, heavy oil pollution and abundant residues, which easily cause stain accumulation and bacterial growth, requiring strict sanitary standards. The entire fish tofu frying line is made of thickened 304 food-grade stainless steel, which is high-temperature resistant, oil resistant, corrosion resistant and rust-proof, fully complying with HACCP food safety specifications. The modular detachable structure allows quick disassembly of the conveyor belt, oil tank, residue scraping components, filter box and oil draining structure for high-pressure water cleaning without sanitary dead corners, saving time and effort in daily maintenance. Core electrical, temperature control, conveying and oil pump components adopt industrial durable configurations, supporting long-term full-load continuous operation in peak seasons and reducing downtime losses.

5. Multi-energy Energy-saving Heating & Fume Purification, Adaptable to Green Large-scale Production

The equipment supports electric, natural gas and thermal oil heating modes to adapt to different factory energy configurations. The inner tank with high-density thermal insulation layer achieves excellent heat preservation, less heat loss, fast temperature rise and high thermal efficiency, reducing energy consumption compared with traditional frying equipment and saving long-term electricity and gas costs. An optional integrated closed fume purification device collects frying fumes in all directions and discharges up-to-standard waste gas after multi-stage purification, improving the workshop environment and easily passing environmental inspections, suitable for small and medium-sized food factories and large prepared food industrial parks.

6. Customizable & Multi-functional, Adaptable to Multiple Specifications and Categories

Equipment length, belt width, heating power and supporting modules can be customized according to factory area, hourly output and product specifications to match exclusive production solutions for factories of all sizes. With strong universality, the equipment is applicable to various surimi products such as fish cakes, fish balls, shrimp cakes and cuttlefish balls, requiring only fine adjustment of oil temperature and belt speed for product switching. It can connect with front-end molding and steaming equipment and back-end air cooling, quick freezing and packaging lines to build a fully automatic deep processing production line for diversified production.

7. One-stop Factory Direct Service, Ensuring Stable Production

Taile Machinery has standardized production workshops and professional R&D teams, providing direct factory supply without middleman markups. We offer free pre-project services including factory layout planning, production line design, output calculation and equipment selection. Professional technicians provide on-site installation, commissioning and operational training after equipment arrival, and deliver standardized fish tofu frying parameters to help enterprises reach production quickly.
