Vacuum frying machine, as an advanced low-temperature frying method, can complete the frying and dehydration process at lower temperatures and in a low-oxygen environment, effectively preserving the natural color, flavor, and nutritional components of food. It is widely used in the processing of fruit and vegetable chips.

Automatic Vacuum Frying Machine Structure and Components:

The vacuum frying machine for fruit and vegetable chips features a compact overall structure and high degree of functional integration, and is mainly composed of the following core components:

Frying chamber: The frying chamber is the core component of the vacuum frying machine, used to complete the frying and dehydration process of materials in a vacuum environment. The frying chamber is usually made of stainless steel, which is corrosion-resistant and easy to clean.
Oil storage tank: The oil storage tank is used to store and circulate edible oil, working in conjunction with the frying chamber. After frying, the oil can quickly flow back to the oil storage tank, reducing the contact time between the material and the oil, thus effectively lowering the oil content of the product.
Vacuum system: The vacuum system consists of a vacuum pump, vacuum valves, and related pipelines, and is crucial for achieving a low-pressure frying environment.

Working Principle of Vacuum Frying Machine for Fruit and Vegetable Chips:

The automatic vacuum frying machine utilizes advanced vacuum low-temperature frying technology, organically combining the frying and dehydration processes. During operation, the materials are placed in a sealed frying chamber, and the pressure inside the chamber is reduced to a negative pressure state below atmospheric pressure through a vacuum system. In a vacuum environment, the boiling point of water is significantly lowered, allowing the water in fruits and vegetables to vaporize rapidly at a lower temperature, thus achieving a dehydration effect. Simultaneously, the frying temperature is typically controlled between 80–120℃, which is far lower than the temperature range of traditional frying.

Vacuum Frying Machine Features:

Automatic control, safe and stable: The frying machine is equipped with an advanced automatic control system that can monitor and precisely adjust oil temperature, vacuum degree, and operating time in real time. The system has multiple safety protection functions, eliminating the risk of overheating and overpressure, ensuring not only the consistency of product quality but also the safety and reliability of the production process.

The oil removal method is flexible and has a wide range of applications: The oil removal system adopts a variable frequency speed control design, allowing for flexible adjustment of the rotation speed according to the characteristics of different types of fruits and vegetables. Whether it’s fruits with a low oil content or root vegetables with a higher oil content, ideal oil removal results can be achieved.
