Lonkia CE Certification Food Processor Industrial French Fries Machine Frozen French Fries Production Line

Product Description

Product Description

The fully automatic frozen French fry production line adopts a complete assembly line operation, and the standard process includes: potato → cleaning and peeling → cutting → cleaning → impurity removal → rinsing → blanching → cooling → air drying → deep frying → degreasing → air drying → quick freezing → packaging → finished product. The blanching process uses hot water at 60-95 ℃ for 4-6 minutes, while the quick freezing process requires a center temperature of ≤ -18 ℃ and a quick freezing time of 30-35 minutes. The entire process is automated to ensure stable product quality
 
The main equipment of the fully automatic frozen french fry production line includes: brush cleaning and peeling machine, hydraulic cutting machine/french fry machine, bubble cleaning machine (at least 2 units), blanching machine, air knife air drying machine (at least 2 units), continuous frying machine, vibration degreaser, quick freezing machine, and automatic packaging machine. The frying machine adopts precise temperature control technology, the degreaser can improve the taste of French fries, and the quick freezing machine ensures that the product quickly passes through the maximum ice crystal formation zone, maintaining the integrity of the cell structure. The equipment material is food grade 304 stainless steel, which meets hygiene standards.

Core equipment composition and characteristics of large-scale French fries production line

The large-scale French fry production line needs to complete the entire process from potato pretreatment to finished product packaging. The technical characteristics of each equipment link directly determine product quality and production efficiency. The Lonkia Group's large-scale French fry production line mainly includes the following systems:

Potato washing machine

Steam Peeling Machine

Hydraulic Cutting Machine

Features: Using a brush roller to remove sediment and impurities, with a built-in spray device to synchronously rinse off the peeled skin and impurities during the peeling process
Key indicators: Processing 3-10 tons of potatoes per hour, equipped with automatic feeding devices to achieve continuous operation.

Efficient peeling: High temperature and high pressure steam (usually 120-140 ℃) is used to instantly penetrate the material skin, combined with rapid pressure relief to cause the skin to burst and fall off. The production capacity of a single device can reach 1000-60000kg/h, with a peeling loss rate of only 4-7%. Compared with traditional mechanical peeling (loss exceeding 30%), it can reduce about 80% of raw material waste

Features: Water jet cutting technology reduces starch loss through high-pressure water flow cutting, with a yield rate of over 95%. The cutting size is adjustable (commonly 3/8 inch, 1/2 inch French fry specifications), and the hourly production can reach 7-8 tons
Advantages: The incision is smooth and free of burrs, avoiding the problem of French fries breaking caused by traditional mechanical cutting.

Spiral Blanching Machine

Steam Frying Machine

Quick-freezing Machine

The temperature control accuracy can reach ± 1 ℃, meeting the requirements of different material blanching processes (such as 60-95 ℃ for vegetables and 80-98 ℃ for meat). Uniform heating without dead corners, spiral blades, materials constantly flip in hot water to avoid local overheating or entrapment. Double layer insulation cylinder combined with heat exchange system reduces heat loss by 30%

1. High pressure steam penetrates the surface of food to form a steam film, reducing the channels for oil penetration. The oil content of the finished product is as low as 12-18% (traditional frying usually 25-35%), and the fat content of French fries can be reduced from 15g to below 8g per 100g.
2. Steam quickly vaporizes the moisture inside the ingredients into a porous structure, which, when combined with hot oil, forms a crispy outer shell

Ultra fast freezing: Using low-temperature strong winds (wind speed 8-15m/s) ranging from -30 ℃ to -45 ℃, the temperature of the food center is reduced from room temperature to below -18 ℃ within 30 minutes through fluidization or belt conveyor. The entire process is automated, and the production capacity of a single tunnel can reach 100-10000 kg/h
Partition temperature control technology: The tunnel can be divided into pre cooling zone (-10 ℃), freezing zone (-35 ℃), and uniform temperature zone (-25 ℃) to avoid surface cracking of food due to excessive cooling

Success Cases

African frozen french fries production line

Customer background: A well-known food group in Africa
Customer pain points:
1. Capacity bottleneck: The daily production of French fries is only 3 tons, which cannot meet the 15% annual growth market demand in the Middle East region;   
2. High raw material loss: Manual peeling and sorting result in a potato loss rate of 28%, far higher than the industry average of 15%;   
3. Unstable quality: The frying temperature fluctuates by ± 5 ℃, and there is a significant difference in product crispness. The customer complaint rate is as high as 8%. 

Solution: 12 ton/day fully automated french fries production line

Comparison of 12-month operational data

Customer evaluation and project impact

Steam peeling machine:1.5T/H ,loss rate ≤ 4%,130 ℃ steam instantaneous bursting skin

Spiral blanching machine:Water temperature 95 ± 1 ℃

Continuous fryer:Oil temperature 170 ℃± 1 ℃, built-in scraper system 

Tunnel freezer:-35 ℃ strong wind freezing, production capacity of 1.5 tons/hour ,Center temperature reaches -18 ℃ within 30 minutes

After the upgrade, the daily production capacity increased from 3T/D to 12T/D, with a 300% increase in production capacity. The use of steam peelers reduced the raw material loss rate from 28% to 7%!

Reduce labor costs by 60% (from 35 people/shift to 14 people/shift), saving approximately $420000 in annual labor expenses;   

"Lonkia Group's fully automatic frozen french fry production line equipment has helped us achieve our goal of 'frying desert potatoes to global quality'. Now our french fries are not only supplied to the local market, but also transported to North Africa and Southern Europe through the Suez Canal, which was unimaginable two years ago. "
