Automatic Commercial 304 Stainless Steel Electric/Gas Donut Making Machine - Core Technical Specifications and Operation Manual

Automatic Commercial Doughnut Making Machine (Note: The display picture is for reference only, please refer to the actual product on the official website)

I. Product Overview

1. Basic Equipment Information

Equipment Name: Automatic Commercial Electric / Gas Optional 304 Stainless Steel Doughnut Making Machine
Product Type: Automatic Commercial Electric / Gas Optional 304 Stainless Steel Doughnut Making Machine
Equipment Positioning: Specially developed for coffee and bakery chain kitchens and enterprises with medium-to-large-volume Western pastry production needs. It is a commercial automated assembly line equipment integrating continuous blanking, intelligent temperature-controlled frying, and mechanical flipping.

Appearance Example and Craftsmanship & Technology Description:

Premium Materials and Hygiene Standards: The machine body, batter hopper, and high-temperature oil tank are all made of high-quality food-grade 304 stainless steel, which is rust-proof and high-temperature resistant, ensuring absolute safety and hygiene in a high-temperature frying environment, greatly extending the service life of the equipment.
Precise Quantitative and Extrusion Technology: Utilizing the precise mechanical piston dropping principle to ensure that the weight and size of each extruded donut batter are highly consistent, perfectly solving the pain points of uneven size and irregular shape caused by manual piping.
Multi-energy Compatibility (Optional Models): Offers TD-2 (Pure Electric Version), TD-2A (Integrated Electric Control Version), and TD-2B (Gas Version) to fully adapt to the energy interfaces and electricity/gas conditions of different countries and commercial kitchens.

2. Core Process and Working Principle

The system breaks through the tedious process of traditional manual batter squeezing and long-term manual guarding in front of the frying pan for flipping, adopting industry-leading automated frying assembly line technology.

Smooth Feeding and Quantitative Cutting: Pour the prepared liquid batter into the upper hopper, and the cutter at the bottom of the machine will continuously and accurately cut the batter rings according to the set frequency, allowing them to fall smoothly into the high-temperature oil tank below.
Automatic Frying and Intelligent Flipping: After the batter falls into the constant-temperature oil tank, it will slowly float forward driven by the internal mechanical paddles. When one side is fried to a golden set shape, the paddle device will automatically flip it to ensure even heating on both sides. Finally, it is automatically pushed out at the end and enters the oil drain tray.

3. Core Positioning: Why Choose Fully Automated Equipment?

For Western restaurants or bakeries with large daily donut sales, fully automated equipment is the only way to achieve a leap in meal output and ultimate standardization:
Disruptive Labor Replacement: Only 1 employee is needed to replenish the batter into the hopper and collect the finished products at the end, completely eliminating the scalding risks and high labor costs associated with manually guarding the frying pan and flipping by hand.
Excellent Capacity and Efficiency: With continuous cycle dropping and frying, a single machine can easily cope with the massive passenger flow consumption during weekends or morning peaks.
End-to-End High Standardization: Precise mechanical quantification and constant temperature control (fixed temperature, fixed speed) ensure that every donut out of the pan is uniformly cooked and not burnt, maintaining extremely high-quality control.

Pure Manual Production vs. Fully Automatic Forming & Frying Machine

Features	Pure Manual Piping/Frying	Fully Automatic Commercial Donut Machine
Capacity Efficiency	Lower (depends on manpower and pan capacity)	High (uninterrupted assembly line operation)
Labor Requirement	Dedicated person needed to monitor throughout to prevent burning	1 operator (just adding batter and collecting)
Product Consistency	Lower (greatly affected by oil temp and manual feel)	Extremely High (smart temp control and timed flipping)
Safety Factor	Prone to hot oil splashing and burns	Automatic operation, operator stays away from the oil tank
Target Users	Small private bakeries, home use	Chain cafes, fast food restaurants, food factories

4. Core Equipment Structure and Hygiene Maintenance Details

In order to better meet the strict requirements of modern high-standard catering for hygiene, cleanliness, and durability, the body design of this equipment has been professionally optimized:

Compact and Sturdy Design: The machine features a scientific structure, stable center of gravity, and moderate volume, making it very suitable for placement on commercial kitchen countertops.
Full 304 Stainless Steel Coverage: The entire casing, hopper, and oil tank are made of 304 stainless steel, which is resistant to high-temperature oil stains and corrosion, making oil draining and cleaning extremely convenient after daily shutdown.
Stable Power and Temperature Control System: Supports precise digital temperature control adjustment. Whether electric or gas heating is selected, it guarantees a robust and stable oil temperature, avoiding excessive oil absorption caused by sudden drops in oil temperature.

II. Production Process and Standard Operating Procedure (SOP)

Below is a guide to core operations and parameter settings based on actual machine debugging:

1. Pre-startup Preparation

Check whether the oil drain valve at the bottom of the machine's oil tank is completely closed.
Pour in an appropriate amount of special shortening or soybean oil, noting that the oil level must reach between the minimum and maximum level marks on the equipment.
Set the required frying temperature and turn on the heating switch to preheat (usually preheated to 170°C - 190°C).

2. Feeding and Operation

Batter Pre-treatment: Pour the prepared batter (neither too thin nor too thick, requiring good fluidity) into the conical stainless steel hopper at the top.
Start Dropping: Once the oil temperature reaches the set value and the indicator light is on, turn on the automatic dropping switch. The forming valve will begin regular operation, cutting off the batter rings and dropping them into the fryer.

3. Forming and Collection

Automatic Flipping Observation: Observe the first few fried donuts and check if their color is uniform. If the color is too dark, slightly lower the temperature or speed up the conveyor chain.
The machine will automatically complete the process of bottom heating, mid-stage flipping, and thorough frying on both sides of the batter rings.
The finished products will automatically fall along the end slide into the receiving tray. Employees can sprinkle powdered sugar while hot or proceed to the chocolate glazing process.

4. Shutdown Cleaning and Maintenance

After work, be sure to turn off the heating switch and cut off the main power/close the gas valve.
Wait for the hot oil to naturally cool down completely to a safe temperature, then open the bottom oil drain valve to discharge and recycle the filtered waste oil.
Disassemble the hopper and internal paddles, wash with neutral detergent and warm water, dry them, and then reassemble.
WARNING: It is strictly forbidden to perform washing operations without draining the hot oil or powering off the machine!

IV. Frequently Asked Questions (FAQ)

Q: Can this machine make donuts of different sizes?
A: Yes. The equipment usually comes with multiple sets of extrusion mold heads of different sizes (e.g., for small, medium, or large donuts). You simply need to replace the discharging mold at the bottom before production to adjust the diameter of the batter rings.
Q: For the gas version (TD-2B), how is temperature control achieved?
A: The gas version also possesses efficient temperature control capabilities. Through micro-electronic control or mechanical temperature control valves, combined with a high-thermal-efficiency burner, it can sensitively maintain the preset temperature in the oil tank, ensuring that the quality of the finished products is highly consistent whether heated by electricity or gas.
Q: Is the machine troublesome to clean? How to deal with residual oil?
A: Extremely convenient. The bottom of the oil tank is designed with a dedicated oil drain valve system. Once cooled, just open the valve to quickly drain it completely. The hopper and conveyor track of the machine have an easy-to-disassemble structure and are all made of 304 stainless steel, which is not prone to dirt accumulation; simply rinse with water and dry it.
