Tempura prawns, tempura squid, vegetable tempura and batter-coated prepared tempura are mainstream best-selling products for aquatic processing factories, prefabricated food manufacturers, central kitchens of chain catering brands and frozen prepared food sections in supermarkets.
Tempura features a thin batter crust for crispy texture. Conventional manual batch frying brings many pain points: ingredients float and pile randomly, causing batter coating to peel off and crust breakage, ruining product appearance. Unstable oil temperature leads to heavy oil absorption and greasy texture at low temperature, or burnt crust and undercooked fillings at high temperature. Plenty of batter crumbs fall off during frying, contaminating and oxidizing cooking oil rapidly. Frequent oil replacement raises production costs. Relying on manual timing makes crispness and color inconsistent between batches, failing standardized supply requirements of catering chains.
As a professional frying equipment manufacturer, TONLE Machinery has specially developed the dedicated automatic tempura frying line targeting the easy-peeling thin batter coating, diversified raw materials and strict temperature requirements of tempura production. It supports continuous processing of tempura prawns, tempura squid, vegetable tempura and batter-coated prepared ingredients.
The complete line realizes integrated operations including automatic feeding, zoned constant-temperature frying, on-line residue scraping & oil filtering and continuous de-oiling discharging. Verified by many frozen prepared food factories, it provides one-stop solutions for industrial challenges such as batter shedding, uneven crust color, high oil consumption and unstable crispness during mass production of tempura.
1. Low-disturbance Flexible Conveyor Belt — Minimize Batter Loss & Guarantee Intact Shape
Tempura batter is thin and fragile. Violent shaking during transportation easily causes crust fragmentation and batter peeling.
TONLE tempura frying line adopts widened low-disturbance mesh belt, with optional gentle pressing limit structure to steadily hold ingredients and reduce rolling and collision. It is equipped with variable-frequency stepless speed regulation system; frying duration can be adjusted freely according to ingredient size and batter thickness.
Seafood tempura gets quick shaping and moisture locking; vegetable tempura achieves even cooking. The crust stays intact and plump with firmly attached batter, golden and fluffy. It effectively reduces coating loss and strengthens market competitiveness of frozen prepared food.
2. PLC Intelligent Zoned Temperature Control — Fluffy Crispy Crust & Tender Juicy Fillings
To achieve crispy outside and tender inside, tempura requires strict oil temperature control. Single temperature cannot balance batter expansion and ingredient cooking.
The equipment adopts PLC intelligent zoned temperature control system with temperature accuracy of ±1℃, applying exclusive two-stage frying technology for tempura:
High-temperature puffing zone at the front quickly expands batter bubbles to form a fluffy crispy crust and reduce oil absorption; constant-temperature cooking zone evenly heats inner ingredients to avoid burnt crust and lock natural juice.
The system monitors oil temperature in real time with automatic temperature compensation and over-temperature audible & visual alarm. It supports 24-hour non-stop continuous production. Color and crispness remain consistent across batches, perfectly matching follow-up air cooling, freezing and packaging processes.
3. Continuous On-line Residue Scraping & Multi-stage Oil Filtration — Extend Oil Service Life
Frying generates constant batter crumbs. Fine residues carbonize under sustained high heat, blackening oil and leaving dark spots on finished tempura and damaging visual quality.
The line is fitted with longitudinal automatic bottom scraper to discharge solid residues during operation, together with external hot oil multi-stage circulating filter to remove fine batter debris and maintain clear oil.
Practically verified service life of edible oil is extended by over 40%, cutting oil replacement frequency and long-term consumable expenses. Fried tempura features clean golden crust.
4. Thickened 304 Food-grade Stainless Steel — Moisture & Oil Resistant, Dead-space-free Cleaning
Frozen prepared food workshops have abundant steam, and batter residues easily cause dirt accumulation.
The whole tempura frying line is constructed with thickened 304 stainless steel, heat-resistant and oil-proof, complying with HACCP food safety specifications.
Modular detachable design enables quick disassembly and washing of mesh belt, oil tank, scraper assemblies and filter units. No hidden corners trap batter debris for easy daily maintenance.
Core components including motors, temperature controllers and oil transfer pumps adopt reliable industrial brands, supporting non-stop operation in peak seasons and minimizing production loss caused by breakdowns.
5. Multi-energy Energy-saving Heating + Fume Purification — Environmentally Compliant Mass Production
The equipment supports electric heating, natural gas and thermal oil heating to fit different factory energy sources.
High-density thermal insulation liner reduces heat loss and accelerates temperature rise. Thermal efficiency is significantly improved, cutting energy consumption by 20%-30% compared with traditional batch fryers and saving long-term energy costs.
Optional integrated closed fume purification unit collects all frying fumes and meets emission standards after multi-stage purification, improving workshop air quality and facilitating environmental inspection. Suitable for small & medium prepared food factories and large prefabricated food industrial parks.
6. Customizable Complete Line & Multi-purpose Function — Expand Categories of Prepared Ingredients
Line length, mesh width and configurations can be customized based on workshop area and hourly output, offering tailored solutions for manufacturers of all scales.
Beyond various tempura products, the line can process battered shrimp, fish fillets, meat patties, vegetable cakes and other prepared ingredients. Only mesh speed and oil temperature need adjusting for product switching.
It can connect front-end battering & coating equipment and back-end air cooling, freezing and packaging units to build a full automatic deep-processing line for tempura.
