Azerbaijani Agriculture and Food Giant: Deploys a 300kg Industrial-Grade Vacuum Low-Temperature Frying System, Breaking the Bottleneck of Charring and Blackening in High-Sugar Fruits and High-Fiber Vegetables
1. Customer Background and Challenges (Background & Challenge)
Customer background: A well-known Azerbaijani leader in deep agricultural processing and export, leveraging high-quality temperate fruit (such as pomegranate, apple, and persimmon) and root vegetable (carrot, beetroot) cultivation bases in the Caucasus region, specializing in the industrial production of high-value-added healthy fruit and vegetable crisps.
Pain points of the Caucasus fruit and vegetable processing industry:
High-sugar fruits are highly prone to the Maillard reaction: Local persimmons, apples, pomegranates, and other fruits contain extremely high levels of fructose and reducing sugars. Traditional hot-air drying or high-temperature frying easily triggers intense Maillard reactions, causing the finished product to darken rapidly, char, and blacken within minutes, and develop a bitter taste.
High-fiber root vegetables absorb oil heavily: Carrots and beetroots have dense tissue, and their oil content remains high after traditional processing, resulting not only in a greasy mouthfeel but also in easy oxidative rancidity during cross-border transportation and storage.
High barriers to cross-border export and supermarket entry: The products are mainly targeted at high-end supermarkets in Central Asia, the Middle East, and the CIS, which impose extremely strict standards on the natural color, dietary fiber retention rate, and oil content of fruit and vegetable crisps.
2. Xinlianxing's Customized Solution (The Solution)
Xinlianxing deployed one LXZK-1300 (300kg-class/Model 1300) industrial-grade vacuum low-temperature frying system for them.
Gentle negative-pressure dehydration process for high-sugar fruits and vegetables: Utilizing vacuum negative pressure to lower the boiling point of water, it rapidly extracts internal moisture from fruits and vegetables in a gentle negative-pressure environment far below the charring point, effectively inhibiting sugar carbonization and perfectly locking in the deep red of beetroot, the vibrant orange of carrots, and the natural original colors of fruits.
Variable-frequency centrifugal de-oiling and continuous bypass fine filtration: Equipped with a variable-frequency centrifugal de-oiling module and a fully automatic continuous fine-filtration oil storage system, it instantly spins off residual oil from the surface of fruits and vegetables and within fiber gaps upon discharge from the tank, filters out shed sugars and particles in real time, and delays the rise in oil acid value and peroxide value.
Thickened anti-corrosion construction and multi-category recipe control: The entire machine is made of thickened SUS304 food-grade stainless steel and paired with a PLC intelligent control system, which can precisely save the dehydration and de-oiling parameters for different fruit and vegetable categories, achieving flexible switching among multiple categories and batch consistency.
3. Quantified ROI & Impact
⚡ 300kg mass-production-level high-efficiency throughput:
Large-capacity continuous delivery: A 300kg-class single-batch processing capacity meets the customer's need for large-volume centralized deep processing during peak fruit harvest seasons.
High utilization rate and one-touch switching: Intelligent control reduces manual operation errors, allowing the factory to complete full-process control with only a few operators, greatly shortening downtime during multi-category switching.
Perfect retention of natural colors and high crispness:
Zero defects in color and quality: Completely eliminating the blackening and bitterness of traditional frying, the finished products present naturally vibrant colors and a refreshing texture of “high crispness, low residual oil.”
Successfully entering high-end international markets: Extremely low oil content and additive-free attributes help the customer smoothly enter high-end supermarket chains in the CIS and the Middle East, achieving doubled agricultural product premiums.
Reduced consumable and oil costs:
Greatly extended frying oil replacement cycle: The bypass continuous fine-filtration system effectively removes charred particles shed from high-sugar fruits and vegetables, significantly reducing the factory's waste oil discharge and consumable expenses.
4. Client Endorsement
**“High-sugar fruits and root vegetables are extremely prone to blackening and bitterness in traditional processing, and their oil content is also difficult to control. The 300kg industrial-grade vacuum low-temperature frying equipment provided by Xinlianxing demonstrated temperature control and de-oiling performance that satisfied us.
Its negative-pressure temperature control and variable-frequency spin-drying system performed exceptionally well. The beetroot, carrot, and fruit crisps fried with it not only perfectly locked in their vibrant natural colors, but their oil content was also reduced to extremely low levels. This equipment has helped us successfully upgrade our locally premium agricultural products into high-premium export-grade healthy snacks; it is our most successful investment in expanding the Caucasus and overseas markets.”**
